As leaders, it is our job to get the very best out of our workforce. We focus on how best to motivate, inspire and create an environment in which employees are satisfied, engaged and productive. This leads us to deliver an excellent customer/client experience.

But all in all, the effort we put into growing our workforce, we often forget the one person who is in constant need of development: ourselves. In particular, we neglect the soft skills that are vital to becoming the best professional possible — one of them being critical thinking.

When you're able to critically think, it opens the door for employee engagement, as you become the go-to person for assistance with issues, challenges and problems. In turn, you teach your workforce how to critically think and problem solve.

Let’s take a look at the key steps in developing critical thinking skills.

What Is Critical Thinking?

One of my favorite definitions of critical thinking comes from Edward Glaser. He said , “The ability to think critically, as conceived in this volume, involves three things:

1. An attitude of being disposed to consider in a thoughtful way the problems and subjects that come within the range of one’s experiences

2. Knowledge of the methods of logical inquiry and reasoning

3. Some skill in applying those methods."

In short, the ability to think critically is the art of analyzing and evaluating data for a practical approach to understanding the data, then determining what to believe and how to act.

The three characteristics of critical thinking include:

•  Being quick and decisive:  One of the most admirable leadership qualities the ability to be quick and decisive with decisions. There are times where an answer just needs to be given and given right now. But that doesn't mean you should make a decision just to make one. Sometimes, quick decisions can fall flat. I know some of mine have.

• Being resourceful and creative:  Over the years, members of my workforce have come to me with challenges and have needed some creativity and resourcefulness. As they spell out the situation, you listen to the issue, analyze their dilemma and guide them the best way possible. Thinking outside the box and sharing how to get there is a hallmark of a great leader.

• Being systematic and organized:  Martin Gabel is quoted as saying , “Don’t just do something, stand there.” Sometimes, taking a minute to be systematic and follow an organized approach makes all the difference. This is where critical thinking meets problem solving. Define the problem, come up with a list of solutions, then select the best answer, implement it, create an evaluation tool and fine-tune as needed.

Components Of Critical Thinking

Now that you know the what and why of becoming a critical thinker, let’s focus on the how best to develop this skill.

1. Identify the problem or situation, then define what influenced this to occur in the first place.

2. Investigate the opinions and arguments of the individuals involved in this process. Any time you have differences of opinions, it is vital that you research independently, so as not to be influenced by a specific bias.

3. Evaluate information factually. Recognizing predispositions of those involved is a challenging task at times. It is your responsibility to weigh the information from all sources and come to your own conclusions.

4. Establish significance. Figure out what information is most important for you to consider in the current situation. Sometimes, you just have to remove data points that have no relevance.

5. Be open-minded and consider all points of view. This is a good time to pull the team into finding the best solution. This point will allow you to develop the critical-thinking skills of those you lead.

6. Take time to reflect once you have gathered all the information. In order to be decisive and make decisions quickly, you need to take time to unwrap all the information and set a plan of attack. If you are taking time to think about the best solution, keep your workforce and leaders apprised of your process and timeline.

7. Communicate your findings and results. This is a crucial yet often overlooked component. Failing to do so can cause much confusion in the organization.

Developing your critical-thinking skills is fundamental to your leadership success. As you set off to develop these abilities, it will require a clear, sometimes difficult evaluation of your current level of critical thinking. From there you can determine the best way to polish and strengthen your current skill set and establish a plan for your future growth.

How to think effectively: Six stages of critical thinking

Credit: Elder / Paul

• Researchers propose six levels of critical thinkers: Unreflective thinkers, Challenged thinkers, Beginning thinkers, Practicing thinkers, Advanced thinkers, and Master thinkers.
• The framework comes from educational psychologists Linda Elder and Richard Paul.
• Teaching critical thinking skills is a crucial challenge in our times.

The coronavirus has not only decimated our populations, its spread has also attacked the very nature of truth and stoked inherent tensions between many different groups of people, both at local and international levels. Spawning widespread conspiracy theories and obfuscation by governments, the virus has also been a vivid demonstration of the need for teaching critical thinking skills necessary to survive in the 21st century. The stage theory of critical thinking development, devised by psychologists Linda Elder and Richard Paul , can help us gauge the sophistication of our current mental approaches and provides a roadmap to the thinking of others.

The researchers identified six predictable levels of critical thinkers, from ones lower in depth and effort to the advanced mind-masters, who are always steps ahead.

As the scientists write , moving up on this pyramid of thinking “is dependent upon a necessary level of commitment on the part of an individual to develop as a critical thinker.” Using your mind more effectively is not automatic and “is unlikely to take place “subconsciously.” In other words – you have to put in the work and keep doing it, or you’ll lose the faculty.

Here’s how the stages of intellectual development break down:

Unreflective thinker

These are people who don’t reflect about thinking and the effect it has on their lives. As such, they form opinions and make decisions based on prejudices and misconceptions while their thinking doesn’t improve.

Unreflective thinkers lack crucial skills that would allow them to parse their thought processes. They also do not apply standards like accuracy, relevance, precision, and logic in a consistent fashion.

How many such people are out there? You probably can guess based on social media comments. As Elder and Paul write , “it is perfectly possible for students to graduate from high school, or even college, and still be largely unreflective thinkers.”

Challenged thinker

This next level up thinker has awareness of the importance of thinking on their existence and knows that deficiencies in thinking can bring about major issues. As the psychologists explain, to solve a problem, you must first admit you have one.

People at this intellectual stage begin to understand that “high quality thinking requires deliberate reflective thinking about thinking”, and can acknowledge that their own mental processes might have many flaws. They might not be able to identify all the flaws, however.

A challenged thinker may have a sense that solid thinking involves navigating assumptions, inferences, and points of view, but only on an initial level. They may also be able to spot some instances of their own self-deception. The true difficulty for thinkers of this category is in not “believing that their thinking is better than it actually is, making it more difficult to recognize the problems inherent in poor thinking,” explain the researchers.

Thinkers at this level can go beyond the nascent intellectual humility and actively look to take control of their thinking across areas of their lives. They know that their own thinking can have blind spots and other problems and take steps to address those, but in a limited capacity.

Beginning thinker

Beginning thinkers place more value in reason, becoming self-aware in their thoughts. They may also be able to start looking at the concepts and biases underlying their ideas. Additionally, such thinkers develop higher internal standards of clarity, accuracy and logic, realizing that their ego plays a key role in their decisions.

Another big aspect that differentiates this stronger thinker – some ability to take criticism of their mental approach, even though they still have work to do and might lack clear enough solutions to the issues they spot.

Practicing thinker

This more experienced kind of thinker not only appreciates their own deficiencies, but has skills to deal with them. A thinker of this level will practice better thinking habits and will analyze their mental processes with regularity.

While they might be able to express their mind’s strengths and weaknesses, as a negative, practicing thinkers might still not have a systematic way of gaining insight into their thoughts and can fall prey to egocentric and self-deceptive reasoning.

How do you get to this stage? An important trait to gain, say the psychologists, is “intellectual perseverance.” This quality can provide “the impetus for developing a realistic plan for systematic practice (with a view to taking greater command of one’s thinking).”

“We must teach in such a way that students come to understand the power in knowing that whenever humans reason, they have no choice but to use certain predictable structures of thought: that thinking is inevitably driven by the questions, that we seek answers to questions for some purpose, that to answer questions, we need information, that to use information we must interpret it (i.e., by making inferences), and that our inferences, in turn, are based on assumptions, and have implications, all of which involves ideas or concepts within some point of view,” explain Elder and Paul.

One doesn’t typically get to this stage until college and beyond, estimate the scientists. This higher-level thinker would have strong habits that would allow them to analyze their thinking with insight about different areas of life. They would be fair-minded and able to spot the prejudicial aspects in the points of view of others and their own understanding.

While they’d have a good handle on the role of their ego in the idea flow, such thinkers might still not be able to grasp all the influences that affect their mentality.

Advanced thinker

The advanced thinker is at ease with self-critique and does so systematically, looking to improve. Among key traits required for this level are “intellectual insight” to develop new thought habits, “ intellectual integrity” to “recognize areas of inconsistency and contradiction in one’s life,” intellectual empathy ” to put oneself in the place of others in order to genuinely understand them, and the “ intellectual courage” to confront ideas and beliefs they don’t necessarily believe in and have negative emotions towards.

Master thinker

This is the super-thinker, the one who is totally in control of how they process information and make decisions. Such people constantly seek to improve their thought skills, and through experience “regularly raise their thinking to the level of conscious realization.”

A master thinker achieves great insights into deep mental levels, strongly committed to being fair and gaining control over their own egocentrism.

Such a high-level thinker also exhibits superior practical knowledge and insight, always re-examining their assumptions for weaknesses, logic, and biases.

And, of course, a master thinker wouldn’t get upset with being intellectually confronted and spends a considerable amount of time analyzing their own responses.

“Why is this so important? Precisely because the human mind, left to its own, pursues that which is immediately easy, that which is comfortable, and that which serves its selfish interests. At the same time, it naturally resists that which is difficult to understand, that which involves complexity, that which requires entering the thinking and predicaments of others,” write the researchers.

So how do you become a master thinker? The psychologists think most students will never get there. But a lifetime of practicing the best intellectual traits can get you to that point when “people of good sense seek out master thinkers, for they recognize and value the ability of master thinkers to think through complex issues with judgment and insight.”

The significance of critical thinking in our daily lives, especially in these confusing times, so rife with quick and often-misleading information, cannot be overstated. The decisions we make today can truly be life and death.

Published on May 30, 2022 by Eoghan Ryan . Revised on May 31, 2023.

Critical thinking is the ability to effectively analyze information and form a judgment .

To think critically, you must be aware of your own biases and assumptions when encountering information, and apply consistent standards when evaluating sources .

Critical thinking skills help you to:

• Identify credible sources
• Evaluate and respond to arguments
• Assess alternative viewpoints
• Test hypotheses against relevant criteria

Table of contents

Why is critical thinking important, critical thinking examples, how to think critically, other interesting articles, frequently asked questions about critical thinking.

Critical thinking is important for making judgments about sources of information and forming your own arguments. It emphasizes a rational, objective, and self-aware approach that can help you to identify credible sources and strengthen your conclusions.

Critical thinking is important in all disciplines and throughout all stages of the research process . The types of evidence used in the sciences and in the humanities may differ, but critical thinking skills are relevant to both.

In academic writing , critical thinking can help you to determine whether a source:

• Is free from research bias
• Provides evidence to support its research findings
• Considers alternative viewpoints

Outside of academia, critical thinking goes hand in hand with information literacy to help you form opinions rationally and engage independently and critically with popular media.

Critical thinking can help you to identify reliable sources of information that you can cite in your research paper . It can also guide your own research methods and inform your own arguments.

Outside of academia, critical thinking can help you to be aware of both your own and others’ biases and assumptions.

Academic examples

However, when you compare the findings of the study with other current research, you determine that the results seem improbable. You analyze the paper again, consulting the sources it cites.

You notice that the research was funded by the pharmaceutical company that created the treatment. Because of this, you view its results skeptically and determine that more independent research is necessary to confirm or refute them. Example: Poor critical thinking in an academic context You’re researching a paper on the impact wireless technology has had on developing countries that previously did not have large-scale communications infrastructure. You read an article that seems to confirm your hypothesis: the impact is mainly positive. Rather than evaluating the research methodology, you accept the findings uncritically.

Nonacademic examples

However, you decide to compare this review article with consumer reviews on a different site. You find that these reviews are not as positive. Some customers have had problems installing the alarm, and some have noted that it activates for no apparent reason.

You revisit the original review article. You notice that the words “sponsored content” appear in small print under the article title. Based on this, you conclude that the review is advertising and is therefore not an unbiased source. Example: Poor critical thinking in a nonacademic context You support a candidate in an upcoming election. You visit an online news site affiliated with their political party and read an article that criticizes their opponent. The article claims that the opponent is inexperienced in politics. You accept this without evidence, because it fits your preconceptions about the opponent.

There is no single way to think critically. How you engage with information will depend on the type of source you’re using and the information you need.

However, you can engage with sources in a systematic and critical way by asking certain questions when you encounter information. Like the CRAAP test , these questions focus on the currency , relevance , authority , accuracy , and purpose of a source of information.

When encountering information, ask:

• Who is the author? Are they an expert in their field?
• What do they say? Is their argument clear? Can you summarize it?
• When did they say this? Is the source current?
• Where is the information published? Is it an academic article? Is it peer-reviewed ?
• Why did the author publish it? What is their motivation?
• How do they make their argument? Is it backed up by evidence? Does it rely on opinion, speculation, or appeals to emotion ? Do they address alternative arguments?

Critical thinking also involves being aware of your own biases, not only those of others. When you make an argument or draw your own conclusions, you can ask similar questions about your own writing:

• Am I only considering evidence that supports my preconceptions?
• Is my argument expressed clearly and backed up with credible sources?
• Would I be convinced by this argument coming from someone else?

Critical thinking refers to the ability to evaluate information and to be aware of biases or assumptions, including your own.

Like information literacy , it involves evaluating arguments, identifying and solving problems in an objective and systematic way, and clearly communicating your ideas.

Critical thinking skills include the ability to:

You can assess information and arguments critically by asking certain questions about the source. You can use the CRAAP test , focusing on the currency , relevance , authority , accuracy , and purpose of a source of information.

Ask questions such as:

• Who is the author? Are they an expert?
• How do they make their argument? Is it backed up by evidence?

A credible source should pass the CRAAP test  and follow these guidelines:

• The information should be up to date and current.
• The author and publication should be a trusted authority on the subject you are researching.
• The sources the author cited should be easy to find, clear, and unbiased.
• For a web source, the URL and layout should signify that it is trustworthy.

Information literacy refers to a broad range of skills, including the ability to find, evaluate, and use sources of information effectively.

Being information literate means that you:

• Know how to find credible sources
• Use relevant sources to inform your research
• Understand what constitutes plagiarism
• Know how to cite your sources correctly

Confirmation bias is the tendency to search, interpret, and recall information in a way that aligns with our pre-existing values, opinions, or beliefs. It refers to the ability to recollect information best when it amplifies what we already believe. Relatedly, we tend to forget information that contradicts our opinions.

Although selective recall is a component of confirmation bias, it should not be confused with recall bias.

On the other hand, recall bias refers to the differences in the ability between study participants to recall past events when self-reporting is used. This difference in accuracy or completeness of recollection is not related to beliefs or opinions. Rather, recall bias relates to other factors, such as the length of the recall period, age, and the characteristics of the disease under investigation.

Identifying the topic

Identifying the topic is the first step in critical analysis of a text.

Topic refers to the word or sentence, which states the main subject of the work, i.e. the issue or idea with which the entire work is related. The work is the author's explanation of the topic. The topic is explicit, and often identified in the main title and should be evident in the abstract or opening paragraph. It answers the pivotal questions of who, what and why through data and facts.

Critical thinking processes:

The critical thinking process has three key elements.

• evaluate and 
• synthesise.
• Identify the parts of an argument.
• deconstruct, divide, determine, resolve, anatomise, cut up, break up, disintegrate, separate, lay bare, dissect, part

When you analyse you:

• identify the main elements of a text, particularly the key ideas, the argument and the evidence
• draw out inferences 
• draw out implications 
• identify persuasive tactics if used.

Examples of language that analyses

The first suggests that........... . The implication is that.......... although.......... .

The second component of the evidence provided is derived from...........and indicates a high level of....... .This could be seen as implying....... .

The third element is comprised of.......... . It supports Wright’s claim in that it........... .

Overall, the research demonstrates........... and.......... .However, it also suggests that........... .

• gauge, appraise, assess, calculate, allocate value, decide, criticise, grade, size up, take measure

When you evaluate you:

• identify the strengths and weaknesses in an argument (credibility)
• weigh up the value of evidence (validity)
• identify and evaluate the assumptions underlying the argument (integrity).

Examples of language that evaluates

The latter, a survey of.........strongly suggests that......... . This evidence is relevant in that it.........and credible in that it.......... .

However, the analysis of the narrative component of the research does not support her assertion that....... .

It suggests rather that........ which undermines her claim that.......... .

Furthermore, it is based on the assumption that.........which is not .........given the ........... .

• to combine; to make whole.
• amalgamate, incorporate, harmonise, blend, integrate, orchestrate, symphonise, unify, arrange, manufacture

When you synthesise you:

• put information together in a new pattern
• provide a new point of view
• show how the relationship between the parts, and between the parts and the whole produce a unique communication.

Examples of language that synthesises

In contrast, Jones (2012), in highlighting...........provides insight into..........and demonstrates a high level of correlation between........and........ .

Jones’s (2012) analytic focus on..........facilitates a further contribution to.......by....... .

Overall, the research demonstrates that..........and.......... .

Ideas to Action (i2a)

• What is Critical Thinking?

The ability to think critically calls for a higher-order thinking than simply the ability to recall information.

Definitions of critical thinking, its elements, and its associated activities fill the educational literature of the past forty years. Critical thinking has been described as an ability to question; to acknowledge and test previously held assumptions; to recognize ambiguity; to examine, interpret, evaluate, reason, and reflect; to make informed judgments and decisions; and to clarify, articulate, and justify positions (Hullfish & Smith, 1961; Ennis, 1962; Ruggiero, 1975; Scriven, 1976; Hallet, 1984; Kitchener, 1986; Pascarella & Terenzini, 1991; Mines et al., 1990; Halpern, 1996; Paul & Elder, 2001; Petress, 2004; Holyoak & Morrison, 2005; among others).

After a careful review of the mountainous body of literature defining critical thinking and its elements, UofL has chosen to adopt the language of Michael Scriven and Richard Paul (2003) as a comprehensive, concise operating definition:

Critical thinking is the intellectually disciplined process of actively and skillfully conceptualizing, applying, analyzing, synthesizing, and/or evaluating information gathered from, or generated by, observation, experience, reflection, reasoning, or communication, as a guide to belief and action.

Paul and Scriven go on to suggest that critical thinking is based on: "universal intellectual values that transcend subject matter divisions: clarity, accuracy, precision, consistency, relevance, sound evidence, good reasons, depth, breadth, and fairness. It entails the examination of those structures or elements of thought implicit in all reasoning: purpose, problem, or question-at-issue, assumptions, concepts, empirical grounding; reasoning leading to conclusions, implication and consequences, objections from alternative viewpoints, and frame of reference. Critical thinking - in being responsive to variable subject matter, issues, and purposes - is incorporated in a family of interwoven modes of thinking, among them: scientific thinking, mathematical thinking, historical thinking, anthropological thinking, economic thinking, moral thinking, and philosophical thinking."

This conceptualization of critical thinking has been refined and developed further by Richard Paul and Linder Elder into the Paul-Elder framework of critical thinking. Currently, this approach is one of the most widely published and cited frameworks in the critical thinking literature. According to the Paul-Elder framework, critical thinking is the:

• Analysis of thinking by focusing on the parts or structures of thinking ("the Elements of Thought")
• Evaluation of thinking by focusing on the quality ("the Universal Intellectual Standards")
• Improvement of thinking by using what you have learned ("the Intellectual Traits")

Selection of a Critical Thinking Framework

The University of Louisville chose the Paul-Elder model of Critical Thinking as the approach to guide our efforts in developing and enhancing our critical thinking curriculum. The Paul-Elder framework was selected based on criteria adapted from the characteristics of a good model of critical thinking developed at Surry Community College. The Paul-Elder critical thinking framework is comprehensive, uses discipline-neutral terminology, is applicable to all disciplines, defines specific cognitive skills including metacognition, and offers high quality resources.

Why the selection of a single critical thinking framework?

The use of a single critical thinking framework is an important aspect of institution-wide critical thinking initiatives (Paul and Nosich, 1993; Paul, 2004). According to this view, critical thinking instruction should not be relegated to one or two disciplines or departments with discipline specific language and conceptualizations. Rather, critical thinking instruction should be explicitly infused in all courses so that critical thinking skills can be developed and reinforced in student learning across the curriculum. The use of a common approach with a common language allows for a central organizer and for the development of critical thinking skill sets in all courses.

The 8 Elements of Critical Thinking

By Med Kharbach, PhD | Last Update: August 12, 2024

Elements of critical thinking are the topic of our blog post today!

Navigating our digitally saturated world feels like wading through an ocean of information. We’ve reached an unprecedented point in history where we’re drowning in data—accessible with just a tap or a click. The very tool that’s revolutionizing our access to knowledge is also becoming a double-edged sword.

On one hand, the democratization of knowledge is an incredible leap forward, comparable to groundbreaking inventions like fire, electricity, and the internet. But, there’s also a downside: the phenomenon of “infobesity,” or information overload. How do we navigate this ocean without drowning? The answer lies in harnessing the power of critical thinking, a multifaceted skill that’s more crucial now than ever.

In this post, we’re going to dig deep into the anatomy of critical thinking—what it is, why it matters, and how to hone this indispensable skill. Along the way, I’ll draw from established thinking taxonomies, scientific studies, and my own experiences as an educational researcher to guide us through. Let’s jump right in!

What is Critical Thinking?

I like to think of critical thinking as an analytic framework, a conceptual structure that weaves together a set of interconnected thinking skills and reasoning abilities. Critical thinking is therefore not a monolithic skill and certainly not a single cognitive ability. 

It is the ensemble of reasoning mechanisms that enable us to synthesize, analyze, process, and evaluate information. It is, as Stanford Encyclopedia of Philosophy defines it, a ‘careful goal-directed thinking’. 

The purpose of critical thinking is to inform our behaviours, actions, decisions and to “improve our ability to reason and generate strong arguments” (Hanscomb, 2016, p. 3). 

The word critical in critical thinking implies two things: First, it implies the existence of a non-critical state of thinking which is the default state underlying the human mind. In this non-critical state, the mind becomes a warehouse of facts, a receptacle of unfiltered ideas and arguments. 

The taken for granted becomes the norm. Conversely,  in the critical state the mind makes use of complex cognitive processes to filter out information and evaluate judgements. The taken for granted is problematised and put to the question. This dichotomy of critical versus uncritical is grounded within a general discussion of thinking skills taxonomies. 

Bloom’s taxonomy, first originated in 1956, is probably one of the most popular taxonomies that attempt to categorize educational objectives into several thinking skills organized along a continuum of cognitive complexity with higher order thinking skills at one end and lower order thinking skills at the other. 

In 2001, Anderson and Krathwohl revised Bloom’s taxonomy and introduced the following six verbs: remember, understand, apply, analyze, evaluate, and create. As Howard et al (2015) argued, “most students focus on the first three parts of this cognitive complexity. 

Critical thinking and creativity depend on the three more advanced parts of cognitive complexity: analyzing, evaluating, and creating” (p. 134)

Indeed, we are thinking animals but only when we become aware of our thinking, that is, when we engage in meta-thinking (thinking about thinking), that we take the first step towards becoming critical thinkers. 

The second implication of the word critical refers to the existence of implicitly biased or distorted norms and that it is the job of critical thinkers  to uncover and expose these distortions. 

One pertinent example in this regard is the phenomenon of fake news . The ability to recognize misinformation is a pure function of critical thinking. Being able to critically appraise and filter information allows one to develop clearer processes of thinking which is why critical thinking is seldom defined as ‘the ability to think clearly and rationally’ .

5 Important Critical Thinking Skills

Critical thinking, as stated earlier, is an analytic framework that consists of several thinking skills some of which include: 

1- Asking questions

The ability to think critically starts with posing serious and deep questions regarding what is normatively considered valid and true knowledge. Critical questions are precursors of deep learning. 

They drive one’s quest to uncover different perspectives, opinions, and dispositions. Critical thinkers do not ask questions for the sake of questions but to spark learning and discovery. They are motivated by a restless need to learn.

2- Problem solving

Critical thinkers are goal oriented. Their objective is to find solutions to emerging problems. These solutions can come in different forms and formats.  Whether it is to find the valid version of a piece of news, uncover the hidden motives behind an author’s statement, understand why things are the way they are, or to simply disambiguate a faulty line of reasoning and refute what appears to be solid arguments, critical thinkers are constantly propelled by an ethical and intellectual obligation to seek alternative perspectives, solutions, and ways of knowing. 

3- Analysing

Analytical practice is at the core of critical thinking. The abilities to ask questions and problem-solve are only effective when coupled with rigorous analytic practice. Analysis is where sifting chaff from grain takes place.  It entails looking at hints, hidden markers, implicit associations and implications and making informed decisions. Critical analysts are sharp observers. They do not simply look but they  see  and  envision  what the laymen can not readily see.  

4- Evaluating

Critical thinkers assess information against multiple criteria and never take propositions for granted. They consider knowledge as socially constructed and relative and is therefore always prone to contention, fallacies, and falsifications. Evaluation involves scrutinizing various sources and perspectives, taking into account excluded voices, and silent viewpoints.

5- Inferring

Inferring is another key critical thinking skill. It allows one to draw conclusions from analyzed data before making any educated guess. 

6- Active Listening

Active listening entails full engagement with the speaker, involving understanding, responding, and retaining the information shared. It enhances learning and problem-solving by ensuring clear communication.

7. Decision Making

Decision making involves evaluating alternatives, assessing evidence, and considering outcomes to choose the best course of action. It relies on critical thinking to make informed, logical judgments.

8. Prioritizing

Prioritizing requires sorting tasks by importance to efficiently manage time and resources. It is crucial for effective problem-solving and project management, ensuring focus on the most critical issues first.

Elements of Critical Thinking

Critical thinking is a process that is composed of a number of elements. Stanford Encyclopedia of Philosophy outlined 11 components of the critical thinking process: observing, feeling, wondering, imagining, inferring, knowledge, consulting, identifying, judging, and deciding. I adapted Stanford’s categorisation of the elements of critical thinking and synthesized them into 8 key elements:

1- Observing

At the observation phase, one notices inconsistencies, irregularities, and abnormalities in their immediate environment. Observing is all about acknowledging the presence of an issue or a problematic that requires further investigation and scrutiny. 

After observing data, one wonders about possible scenarios, plans, actions, behaviours, etc that could have been applied but were not. Wondering is about posing questions and imagining possible answers.

3- Gather information

To seek answers to their questions, critical thinkers gather information from different sources. Their goal is to cover the issue from different angles and explore as many perspectives as possible. All possible sources of data are vetted with an eye on inconsistencies, differences, divergences and contradictions.

Analysis is an important element of the critical thinking process. It is through analysis that critical thinkers deconstruct arguments, reveal implicit biases, and explore alternative viewpoints. Analysis is a methodical process that entails examining and re-examining data searching for patterns of thought and identifying structural discrepancies

5- Synthesize

The next step after collecting data from multiple sources and analyzing it is to synthesize it. Critical thinkers put disparate ideas, assumptions, facts, and propositions together and combine them into an overarching argument. 

Effective synthesis requires deeper levels of understanding because one can only deconstruct and combine ideas after they have fully internalized them. 

Reflection is another central element of the critical thinking process. Reflection is an iterative process in which one re-assesses their analytical and argumentative logic searching for possible influences, biases, and prejudices that might have impacted their reasoning.

7- Identify

After gathering information, analyzing it and reflecting on it, the critical thinker is now in a position to identify problematic areas and isolate inconsistencies.  The key is to narrow the broad scope of an argument and deconstruct its structure in such a way that it becomes easier to tackle, one problem at a time.

The last element of the critical thinking process is taking decisions. As I stated earlier, the purpose behind critical thinking is for us to be able to make informed decisions, that is, decisions based on solid facts and arguments. 

Characteristics of Critical Thinkers

Critical thinkers are normal individuals like everybody else except that they have developed strong cognitive filters that help them navigate the world in  more nuanced ways. Given their preoccupation with deeper forms of understanding , critical thinkers have developed unique characteristics including

➥  Empathetic : Critical thinkers are empathetic individuals. They acknowledge and understand the feelings of others, build affinities and sympathise with them.

➥  Flexible : critical thinkers are guided by logical and reasoned argumentation and therefore have no problem changing their positions and beliefs whenever a new convincing evidence emerges.  

➥  Hard working : Critical thinkers do not take shortcuts. They compare and contrast different sources, vet resources, debate arguments, uncover hidden relations and interconnections, and put the work necessary to reach what they believe are valid conclusions. 

➥  Independent : Critical thinkers do not swear allegiance to any creed, dogma, tribe, or ideology. Their creed is logic and reason. They thrive in intellectual freedom and have a deeper sense of responsibility and respect for others. Critical thinkers are self-directed and independent life-long learners.

➥  Reflective:  Critical thinkers are reflective individuals. They constantly reflect on their actions, thinking processes, emotions, and feelings. They always seek to uncover new shades of meanings, discover hidden feelings and reactions, and optimize their reflective practice.

➥  Objective:  Critical thinkers recognize their biases and personal assumptions and are explicit about their influences. Their methodology is evidence-based.

➥  Observant:  Critical analysts have an acute sense of observation and a sharp eye for detail. They view the minutiae of everyday life as possible sources of insightful data and the path towards enlightening hunches. 

Examples of What Critical Thinkers Can Do

Critical thinkers are able to :

• Identify fallacious arguments and provide counter-arguments.
• Conceptualize and analyze ideas effectively.
• Synthesize information from various sources into solid arguments.
• Evaluate information, compare and contrast it, and identify argumentative strengths and weaknesses.
• Structure arguments along a clear and logical order breaking down complex concepts into digestible ideas.
• Use different forms of data collection methods to gather information including observation, experience, reading, reflection, etc.
• Read between and beneath lines , access hidden meanings, and expose implications.

Final Thoughts

In this digital age where information overload is the norm rather than the exception, the call to arms is clear: Equip yourself with critical thinking skills. Far from a monolithic concept, critical thinking is an intricate tapestry of cognitive abilities that empower us to analyze, evaluate, and synthesize the world around us. From grappling with the constant bombardment of facts and fallacies in the media to dissecting the implicit biases that often go unnoticed, the value of critical thinking is incalculable.

What is Critical thinking? 

There are many definitions of Critical thinking. Some of them very long and comprehensive in coverage of everything critical thinking includes, while others are short definitions but  very succintly summarize what Critical thinking is and what leads to becoming a critical thinker. Here are three of them.

1. "Critical thinking is the process of making clear reasoned judgments" ...Beyer, 1995

2. “Critical thinking is the ability to look at a situation and clearly understand it from multiple perspectives while separating facts from opinions, myths, prejudices, hunches (intuition) and assumptions”….. Pearsons

3. "It involves the ability to questions assumptions etc. in order to make logical decisions based on consideration of the options and evaluation of all facts". … Pearsons

What do you need to learn to become a critical thinker? 

All of us know critical thinking by its absence or critical thinking traits that we see in a person. When someone makes a foolish decision or applies the first solution that comes to their mind in problem-solving, we know that critical thinking has not been exercised. But critical thinking itself has not been defined for  most of us -either in our education or later in the workplace.

Maybe we see Critical thinking as applied common sense. Critical thinking may also be defined as the process of making clear reasoned judgments about any claim, issue, or solution to a problem. Some also define it as the process of determining whether a claim is true or false. There are more complex definitions such as Critical thinking is skilled and active participation and evaluation of observations and communications, information, and argumentation (Fisher and Scriven). 

None of the academic definitions manage to communicate what Critical thinking is, its elements, and how it could be useful in the workplace, education, or life. To better understand what Critical thinking is, it is useful to look at the actual elements that go into Critical thinking, and see how they apply in various situations at work and in life.

Critical thinking is the process of making clear reasoned judgements. 

Elements of critical thinking

There are three elements that aid in critical thinking, and another three that obstruct critical thinking.

Logical reasoning: You would not expect an accountant to draw up a balance sheet without the knowledge of the debit/credit system. However, we are expected to be absolutely logical in our reasoning about problems and decision making. The absence of a formal introduction to logical reasoning results in even the most intelligent people miss a few steps in their reasoning. There are three main types of reasoning: Deductive reasoning, Inductive reasoning, and Causal reasoning. Of these, Inductive reasoning and Causal reasoning as the most commonly applied systems of logic in the workplace, education, and our daily life.

Clear thinking and communication: Discussions often end up at cross-purposes and pointless due to a lack of clear communication, and this lack of clarity is often due to a lack of definition of terms, ambiguity, and deliberated or unintended use of vague language.

Credibility: We are often required to evaluate suppliers and people to decide whether to work with them or not. We also rely on the opinions of others to make a varying range of decisions for the business, in education and life. How do we know how much credibility we should attach to the advice we get from these people, or how do we determine whether a supplier will be dependable or not? There are some simple principles that we can use to help us in our process of making judgments about credibility.

Elements that obstruct 

  Rhetoric: In the context of Critical thinking, rhetoric is the use of language to evoke emotions in us and persuade us into belief or action. Words have the power to express, elicit images, and evoke emotions in us. They have tremendous persuasive power or what can be called rhetoric force or emotive force. When a leader calls on soldiers to sacrifice lives for the sake of their country, or when citizens are passionately asked to join a protest to protect freedom, these are appeals to our emotions and not our logical reasoning. Rhetorical language and devices can cloud our ability to reason logically.  

Cognitive biases: A cognitive bias is a systematic error in our thinking and judgment and can be due to a number of different reasons such as faulty memory or perception and processing errors of our brains. There could be a number of other reasons, and scientists are still researching the causes of these cognitive biases. A cognitive bias is different from Fallacies in the sense that these errors are based on our incorrect perception and processing of information by our brains, whereas fallacies are simple errors in reasoning. Knowledge of fallacies can help us avoid reasoning errors, but cognitive biases may arise even if we have knowledge of these biases. Often the only way to mitigate errors due to cognitive biases is to rely on data or seek third party opinions.

The Peak Performance Center

The pursuit of performance excellence, critical thinking.

Critical thinking refers to the process of actively analyzing, assessing, synthesizing, evaluating and reflecting on information gathered from observation, experience, or communication. It is thinking in a clear, logical, reasoned, and reflective manner to solve problems or make decisions. Basically, critical thinking is taking a hard look at something to understand what it really means.

Critical Thinkers

Critical thinkers do not simply accept all ideas, theories, and conclusions as facts. They have a mindset of questioning ideas and conclusions. They make reasoned judgments that are logical and well thought out by assessing the evidence that supports a specific theory or conclusion.

When presented with a new piece of new information, critical thinkers may ask questions such as;

“What information supports that?”

“How was this information obtained?”

“Who obtained the information?”

“How do we know the information is valid?”

“Why is it that way?”

“What makes it do that?”

“How do we know that?”

“Are there other possibilities?”

Combination of Analytical and Creative Thinking

Many people perceive critical thinking just as analytical thinking. However, critical thinking incorporates both analytical thinking and creative thinking. Critical thinking does involve breaking down information into parts and analyzing the parts in a logical, step-by-step manner. However, it also involves challenging consensus to formulate new creative ideas and generate innovative solutions. It is critical thinking that helps to evaluate and improve your creative ideas.

Elements of Critical Thinking

Critical thinking involves:

• Gathering relevant information
• Evaluating information
• Asking questions
• Assessing bias or unsubstantiated assumptions
• Making inferences from the information and filling in gaps
• Using abstract ideas to interpret information
• Formulating ideas
• Weighing opinions
• Reaching well-reasoned conclusions
• Considering alternative possibilities
• Testing conclusions
• Verifying if evidence/argument support the conclusions

Developing Critical Thinking Skills

Critical thinking is considered a higher order thinking skills, such as analysis, synthesis, deduction, inference, reason, and evaluation. In order to demonstrate critical thinking, you would need to develop skills in;

Interpreting : understanding the significance or meaning of information

Analyzing : breaking information down into its parts

Connecting : making connections between related items or pieces of information.

Integrating : connecting and combining information to better understand the relationship between the information.

Evaluating : judging the value, credibility, or strength of something

Reasoning : creating an argument through logical steps

Deducing : forming a logical opinion about something based on the information or evidence that is available

Inferring : figuring something out through reasoning based on assumptions and ideas

Generating : producing new information, ideas, products, or ways of viewing things.

Critical Thinking, Its Components and Assessment

In higher education and advanced education exemplified by graduate school education, demonstrating critical thinking skills is crucial to good scholarship. But what really is critical thinking? How is it demonstrated and how can professors measure such level of thinking?

In general, how can we employ critical thinking to discern fact from fiction? How can we avoid being misled? Again, I highlight the important points in this discussion.

Table of Contents

Introduction.

In a fast-paced world where information and data flood our daily lives, it is increasingly essential to navigate with discernment, clarity, and analytical acumen in both personal and professional spheres. This necessity is where the profound relevance of critical thinking becomes clear.

Encompassing components like analysis, interpretation, and self-regulation, critical thinking is a cognitive process that enriches decision-making, problem-solving, and quality management across varied sectors.

This discussion will delve into what critical thinking entails, why it holds utmost significance in today’s world, the integral skills and dispositions it comprises, and how it can be effectively developed and measured.

Defining Critical Thinking

Critical thinking defined.

Critical thinking refers to the ability to analyze information objectively and make a reasoned judgment. It involves the evaluation of sources, such as data, facts, observable phenomenon, and research findings.

Critical thinkers can separate facts from opinions, evaluate credibility, identify prejudice or bias , distinguish between relevant and irrelevant information, and ascertain the validity of the information. This involves clear, rational, open-minded, and informed thinking.

So, what is critical thinking exactly? It’s the capability to think in a clear and rational manner about what actions to take or beliefs to hold. It includes the ability to independently engage in reflective thinking .

The Critical Thinking Mindset

Beyond the very technical aspects, critical thinking fundamentally involves a mental discipline that calls for reflective mindfulness, a sense of skepticism, and intellectual humility . Balancing these qualities with curiosity, creativity, and an appreciation for complexity, this mindset becomes pivotal within the decision-making process.

Essentially, the adoption of a critical thinking mindset allows for a robust evaluation of different possibilities. This process is based on established criteria and standards that enable clear, rationale thought, thus unlocking more informed, evidence-based decision making.

The Importance of Critical Thinking

Critical thinking plays a crucial role in professional environments. It is integral in problem-solving and decision-making processes, enabling professionals to analyze issue-related data, consider alternate perspectives, and make informed decisions based on sound reasoning and evidence.

Critical thinking is often assessed through various assignments, presentations, class discussions, and project-based activities. The purpose of these tasks is not only to measure a student’s ability to process and synthesize information but also their ability to draw connections between different concepts and build up well-reasoned arguments.

In science, for example, critical thinking helps researchers design experiments, interpret data, and derive conclusions. In business, critical thinking assists organizations in strategic planning, problem-solving, decision-making, and innovation. In education, critical thinking is crucial in developing skills in reading, writing, and learning.

Furthermore, critical thinking can foster creativity by necessitating the exploration of multiple viewpoints and solutions, it can enhance communication by promoting clarity, accuracy, and relevance in the exchange of ideas, and promote social harmony by encouraging open and objective discussions.

6 Components of Critical Thinking

1. analysis.

This involves examining information in detail in order to understand it better and to draw conclusions. It could be data , a concept , or a process .

2. Interpretation

This is the act of explaining the meaning of information . Critical thinkers deeply focus on a topic or issue, questioning and analyzing it from multiple perspectives.

Interpretation refers to the ability to understand and express the meaning or significance of a wide variety of experiences, situations, data, events, judgments, conventions, and criteria. It also involves making inferences — drawing out unseen implications from the information given.

3. Inference

It is the act of deriving logical conclusions from premises known or assumed to be true. Inferences can be accurate or inaccurate, logical or illogical, justified or unjustified.

4. Explanation

5. evaluation.

Evaluation in critical thinking refers to the process of determining the credibility and relevance of the information. This involves assessing the evidence supporting a claim, determining its source’s reliability, and judging the logical consistency of arguments.

Returning to the political debate example, evaluating might involve checking the sources of factual claims or judging whether the proposed solutions are feasible given the present socio-political conditions.

6. Self-Regulation

Dispositional elements of critical thinking, open-mindedness.

Open-mindedness involves being receptive to new ideas or conflicting perspectives. It implies the willingness to revise pre-existing beliefs based on new evidence or understandings. This characteristic helps critical thinkers avoid biases, consider all available evidence, and make fair judgments.

Intellectual Humility

Intellectual courage.

Intellectual courage refers to the willingness to evaluate all ideas and beliefs, even those that conflict with one’s own. Challenging comfortable assumptions in pursuit of truth is essential for critical thinking.

How to Develop Critical Thinking Skills

1. pursue continuous learning.

To hone your critical thinking skills, continuous learning is of paramount importance. This includes opening oneself up to an array of experiences and environments, entertaining diverse viewpoints and actively seeking opportunities to challenge your pre-existing beliefs.

Anyone who stops learning is old, whether at twenty or eighty. Anyone who keeps learning stays young.

2. Challenge the Status Quo

Being a critical thinker also involves questioning the accepted norms and challenging the traditional wisdom. Instead of simply accepting things as they are, delve deeper to understand the reasons behind their existence.

3. Understand Diverse Perspectives

4. embrace calculated risks.

Developing your critical thinking skills may entail taking calculated risks. This includes stepping out of your comfort zone to experience new things and ideas that might challenge your previous assumptions. This involves a careful analysis of the pros and cons before making an informed decision based on your findings.

5. Promote Open-Mindedness

6. keep a reflective journal, measuring critical thinking.

Critical thinking can fundamentally be described as one’s aptitude to assess, conceptualize, apply, and critically examine information gathered or produced through various means, such as observation, dialogue, reflection, or reasoning. This intellectual process encourages making well-reasoned judgments based on solid evidence and logic rather than accepting arguments and conclusions at face value.

How we measure critical thinking, however, can vary. While these capabilities may sound subjective, there are objective ways on how to measure critical thinking. I enumerate some of them in the next section.

1. Standardized Tests to Measure Critical Thinking

The Ennis-Weir Critical Thinking Essay Test measures the ability of students to reason through a problem and to express their reasoning in writing. This type of measurement tool is used mainly in educational settings, but it offers valuable insight into individual critical thinking skills.

2. Performance Assessments

Specific critical thinking aspects might be identified and evaluated using rubrics – criteria set to ascertain a person’s ability to identify, summarize, and offer solutions to problems while also taking various perspectives into account.

3. Self and Peer Evaluations

In addition to the aforementioned, self and peer evaluations provide another measure of critical thinking. These require individuals to introspect on their cognitive processes or inspect the same in their peers.

Interpreting The Results

Key takeaways.

As we stand in an era of information overload, the value of critical thinking in deciphering truth from noise cannot be overstated. It enhances our ability to analyze, interpret, evaluate, and take calculated risks in various facets of life, ensuring we make informed, intelligent decisions.

As effortlessly as it might seem to come for some, critical thinking, like any other skill, can be cultivated and honed over time with dedication and the right strategies. These skills can be measured with tools like the Watson-Glaser Critical Thinking Appraisal, leading to a more informed understanding of an individual’s critical thinking capabilities.

Therefore, investing in the development and assessment of critical thinking skills is an investment in a more discerning, informed, and intellectual society.

In conclusion, critical thinking is not only a valuable but a crucial life skill. In today’s information-rich world, the ability to analyze data and make swift, efficient decisions is vital. Thus, understanding critical thinking and its significance, and knowing how it is measured and can be improved, is key to personal and professional growth.

3 Ways to Build Critical-Thinking Skills

When was the last time you practiced your critical thinking skills?

• Apple Podcasts

When was the last time you practiced your critical thinking skills? Helen Lee Bouygues , an expert in business transformation, says many business problems are really about simple errors in critical thinking.

“People believe that critical thinking is something that we do every day and it comes very natural,” she tells IdeaCast host Curt Nickisch . “But in reality, critical thinking is not only extremely important for success in life, but it’s also something that needs to be learned and practiced.”

In this episode you’ll learn how to practice your critical thinking skills. Bouygues outlines three key components of critical thinking: questioning your assumptions, reasoning through logic, and diversifying your thought process.

Key episode topics include: strategy, strategy formulation, decision making and problem solving, managing yourself, critical thinking, managing emotions, strategic decisions.

HANNAH BATES: Welcome to HBR On Strategy , case studies and conversations with the world’s top business and management experts, hand-selected to help you unlock new ways of doing business. When was the last time you practiced your critical thinking skills in your business? Helen Lee Bouygues says many business problems are really about simple errors in critical thinking. Bouygues is an expert in business transformation and she’s been an interim CEO, CFO, or COO at more than a dozen companies. In this episode you’ll learn how to improve your critical thinking skills for business – through (you guessed it) practice. Bouygues outlines 3 key components of critical thinking: questioning your assumptions, reasoning through logic, and diversifying your thought process to avoid selective thinking. You’ll learn how to practice each and why building in time to think without distractions can also help you make better decisions.  This episode originally aired on HBR IdeaCast in July 2019. Here it is.

CURT NICKISCH: Welcome to the HBR IdeaCast from Harvard Business Review. I’m Curt Nickisch. You know the story. Maybe it’s even a nightmare of yours. One day, the company is flying high. No reason to change anything. Customers and contracts will always be there. And then one day – the money stops flowing in, and the business is suddenly in real trouble. Our guest today knows this all too well. She has been an interim CEO, CFO, or COO at more than one dozen companies. Sometimes they needed her because they were mismanaged. Some failed to stay in front of changing technologies. In a few cases, members of the senior team were simply negligent. But in her experience, all these organizational problems shared one root cause: A lack of critical thinking. Our guest is Helen Lee Bouygues. She’s the founder of the Reboot Foundation. Based in Paris, the nonprofit helps parents, teachers and employers think more critically about their problems. She’s also the author of the HBR.org article “3 Simple Habits to Improve Your Critical Thinking.” Helen, thanks for being here.

HELEN LEE BOUYGUES: Thank you for having me, Curt.

CURT NICKISCH: Helen, you worked in transitional periods for a bunch of big companies. And, you say that many people’s business problems really come down to simple errors in critical thinking. That just sounds a little surprising to me and I wanted to hear why you say that.

HELEN LEE BOUYGUES: Yeah, I think at first glance people believe that critical thinking is something that we do every day and it comes very natural. But in reality, critical thinking is not only extremely important for success in life, but it’s also something that needs to be learned and practiced. Critical thinking skills are very much predictive of making positive financial decisions, even more so than raw intelligence, but people kind of forget what that actually means in terms of tools and practices that they need to exercise in order to make the right decisions, or at least the better decisions. Based on my 20 years of different turnaround and transformation experience, I have noticed that very often when things go sideways or create problems and companies find themselves in a situation of a need for turnaround, it’s typically been because I would argue that the leadership perhaps lacked some elements of critical thinking.

CURT NICKISCH: Why do you think we lack critical thinking skills, or why do you think we think we’re better at it than we actually are?

HELEN LEE BOUYGUES: That’s a great question Curt and actually we did a survey at the Reboot Foundation about a year ago, where we asked people questions of everything from ranging from how often do they practice critical thinking to how important they think critical thinking is, and how often they teach their children critical thinking? I think one of the reasons why it’s more difficult in today’s day and age is that we live in a world of incessant distraction and technology is often to blame as well. We live in a period when we have a question, we want that instant gratification getting the information, just typing the question on Google, having the answer quickly and so, we don’t actually have as much time to stop and think. And part of the necessity of critical thinking is having that ability to take a step back and actually think about your own thinking. And yet, it’s actually becoming more and more critical because as businesses evolve and there’s more urgency to make decisions, that’s exactly when we need to do more critical thinking than perhaps we used to, because of evolving technology and rapidly changing competitive environments in business.

CURT NICKISCH: You say that getting better at critical thinking is something we can learn and cultivate?

HELEN LEE BOUYGUES: Yes. The opposite of critical thinking could be selective thinking. And naturally selective thinking is something that you can actually do relatively quickly because it’s just a reinforcement of your own opinion. People in business can get better at critical thinking if they just do three things. One, question assumptions. Two, reason through logic. And three, diversify thought.

CURT NICKISCH: How do you actually do that?

HELEN LEE BOUYGUES: So, the taking a break, and that doesn’t mean doing meditation or yoga, but actually taking the time. It could be going for a run, or a walk around the block. That alone creates that opportunity for an individual to take the time to stop and think. So, that’s one dimension I think that people need to put in their normal practice. The second element that you wouldn’t necessarily think about in terms of an attribute necessary for critical thinking is management of emotions. So, the number of times that you can imagine, especially in a boardroom for a company that’s going through a difficulty, heated discussions, insults across the room. In that type of environment, it’s very difficult to engage in rational thinking. As much emotions are important, when it comes to true important decisions, we need to put aside the feelings and emotions that go awry in a meeting setting. In addition to that, I think the other element of what we need to make sure that we conduct is making sure that we have other points of views.

CURT NICKISCH: When you talk about looking at things from opposing viewpoints, sometimes that’s helpful when you have somebody who plays that role, or when you have a diverse team that you can share ideas with and explore. I don’t know that all of us are as good of just thinking from other perspectives when we’re kind of just in our own thoughts.

HELEN LEE BOUYGUES: Yeah, but it’s again, that’s why I think I started off this conversation Curt, in saying that critical thinking is something that you actually need to practice and you need to learn. Because indeed, it’s natural and it’s very human to stay in your own personal bubble because it’s comfortable. But you can actually do this from a small scale to a larger scale, and what I mean by that specifically is if you’re starting small, if you work in for example, in accounting. Go have lunch with people in marketing in your organization. I have a good friend, Mathilde Thomas, she’s actually the founder of Caudalie which is a very successful line of skincare products made from grapes. Mathilde grew up spending her time in her family vineyards, so her family originally was in the wine business. And the idea of the skincare product came about because one day a friend of the family, this physician, came to visit the vineyard and he was looking at the vat of grape skins that were about to be discarded and he said, well that’s a pot of treasure, so why are you just discarding that away? And that’s effectively how the business of Caudalie actually began. So, that’s a positive story where people who are not necessarily in the same field can get together and actually come up with innovation or here it wasn’t even intended to be an innovation. It just was an idea that sprung from two people from different walks of life getting together and coming up with the business idea. So, that’s a positive example in terms of diversity.

CURT NICKISCH: Where have you seen this failure in some of the companies that you worked with? Where have you seen the inability to diversify thought and opinions and host costly that can be?

HELEN LEE BOUYGUES: I think in terms of negative, I’ve seen a specific example for a pharmaceutical company where the founder brought in a CFO who actually had very little experience in accounting. He had experience in mergers and acquisitions, in elements of financing, but not pure accounting. But his true qualification of becoming the CFO was the fact that he was a very, very good friend of the CEO’s and you see that example over and over again, including in boards. The number of times you see the board of a company being surrounded, the CEO being surrounded by his or her friends, which is why often I think from time to time, you have companies, publicly listed companies where sometimes the board may not see certain indications. Be it the case of a Steinhoff or an Enron, which is an extreme case of fraud, but even in terms of general decisions, strategic decisions, that if you have a board composed of just a group of friends of the CEO’s, you don’t have diversity of thought in that type of environment.

CURT NICKISCH: So, we’ve talked some about questioning assumptions and the power of diversifying thought. But another point you make is that people need to get better about reasoning through logic. And I think this is going to surprise people too because logical is just such a household word. We think that we think logically, so why is logic a deficit and kind of a prerequisite for the critical thinking you think we need to see more of in management?

HELEN LEE BOUYGUES: So, one of the stories that I like to bring up is a specific company that I encountered a couple of years ago. It’s one of the world’s largest producers of aluminum tubes and they have clients ranging from L’Oréal to Proctor and Gamble, all over the world.

And the CEO of this company was blindsided by his own fervor and probably unreasonable optimism about the outlook for the revenue profile of this company. In reality, the company was in relatively dire financial straits, but again he was blinded with his hope that his clients would never leave because the switching costs of his clients would be too high, or that at least was his hypothesis. And for some business leaders I think some optimism is obviously a good thing. There wouldn’t be Ubers or EBays if we didn’t have entrepreneurs who have that charisma and exuberance. But what I often find in companies is CEOss with something I call simply WTF. Now Curt, that’s not what you think that we commonly use in text messages, but it’s for me it’s “wishful thinking forever’. And I think that blinded optimism can often mask the capability and the ability to reason through logic and actually re-question your approach and saying, “well, can my customers decide to change vendors? Is the competitive environment actually shifting? Are there low-cost companies that could actually take over my business even if that hurdle rate is high?” So, it’s again coming back to being able to ask the right questions and looking at your business and saying, “is there a different way of doing things?” And that’s when you avoid the pitfalls of actually reasoning through logic. And it comes back to the argument of having different views from your original views and your original sentiments. And obviously in order to do that, we need to really pay close attention to our own chain of logic.

CURT NICKISCH: Which I like by the way, wishful thinking forever. I’m going to read text messages that way now. Probably make them a little more optimistic. Yeah. A lot of companies pay consultants to do this kind of critical thinking for them and they come in with tools and concept mapping, and all of the sorts of things that maybe they’re a little more deliberate about and also, removed from the emotion of working in the culture of a company. Do you see consultants as essentially paid critical thinkers?

HELEN LEE BOUYGUES: I think many consultants are good at critical thinking. I don’t believe that the industry of management consulting is a sector that is there to enforce critical thinking for companies. And let me explain why I believe that. A lot of, in a lot of situations CEOs seek validation and look for evidence that supports their preconceived notions. And consultants are often trained to agree with their client’s theories. So, I would almost counter argue and say, for CEOs to effectively use consultants, they almost need to be very precise and be very upfront in their scope of work with the consultants, demand and ask that the consulting firm give a different point of view, or an opposing point of view than the original thesis of a leader. Now that is sometimes hard to do. It goes back to the original part of our discussion. It’s less comfortable for leaders and in a lot of situations why CEO’s are hiring consultants are to justify and explain with more detail to their boards of why they’re doing certain strategic activities. So, that’s where we have to be careful about relying on consultants as quote, “a mechanism to do better critical thinking in business”.

CURT NICKISCH: Have you actually seen companies turn around when they change the way they approach problems and instituted critical thinking across the organization in a more deliberate way?

HELEN LEE BOUYGUES: Yes. I worked with a telecom company in Africa, not so long ago. And they had probably the lowest customer satisfaction rate across the board, amongst the different countries in Africa. And the CEO was somebody who was a very open minded, wanted to challenge – now you could argue Curt, they were on the low, they couldn’t get lower in terms of customer satisfaction, so they only had room to go up. But if you put that aside, what he instituted was to have a sub group of his team to go visit another South African country that had very high customer satisfaction rates. So, it was, I would call creating an environment for its employees to have a bit of a diversity of thought, but also to actually be exposed to give the capacity for its employees to question the assumptions about what they were doing wrong. So, very good CEOs not only are capable of trying to conduct metacognition for him or herself, meaning questioning his or her own way of thinking, but he’ll challenge his team and help them to challenge their own way of thinking by showing different examples of for example, success stories in the same type of work where in a case of this telecom company in Africa, where they could see and visit customer services centers in other African countries where they had high customer satisfaction rate. So, it’s giving the exposure to its team to seek out diversity of thought, but also promoting that, and encouraging that its employees think differently than being focused on their own silos of work and being, trying to be efficient in their own capacity, in their existing dimension.

CURT NICKISCH: Yeah. So, if that was a good critical thinker, as a CEO, what do most leaders do in that situation? What does the “uncritical thinker” do?

HELEN LEE BOUYGUES: The uncritical thinker would be to try to gain more efficiency out of its existing employees and continue to do more of the same thing. But probably putting in more KPI’s. That’s a popular thing that leaders do. And try to put more pressure in the system so that companies are more productive. Rather than thinking out of the box and trying to say, should we be doing something differently than the way we’re doing it today?

CURT NICKISCH: And for individuals? Because whether or not you have a CEO who’s good at this, you can still affect your own team and you can still affect your own work with your own critical thinking. What should they do to get better at critical thinking?

HELEN LEE BOUYGUES: Be curious. Ask the questions. “ What if” questions are great. It’s important to constantly challenge yourself saying, what if I did something differently than the way I’m doing it now? What if I approached my client differently than the way I’m doing it now? What if I changed the processes? Would there be improvement? That’s the type of individual who can improve by actually questioning the assumptions of what he or she is doing on a daily basis. And then the second element again, is trying to be very factual and be rigid about gathering facts and proof and accumulating data in order to truly justify why you’re doing what you’re doing. It’s going back to paying close attention to the chain of your own logic. And then the third is expanding your horizon by interacting with people that are not in your existing silo. So, I go back to the example, very simple example, go have lunch, go have a drink with somebody that’s not in your same department, but go reach out to somebody who’s in a totally different building, or even different division within your group.

CURT NICKISCH: Helen, thanks for coming on the show and talking about thinking through how to be a better critical thinker.

HELEN LEE BOUYGUES: Thank you so much. It was a real pleasure to be on your show.

How to build your critical thinking skills in 7 steps (with examples)

Critical thinking is, well, critical. By developing critical thinking skills, you improve your ability to analyze information and come to the best decision possible. In this article, we cover the basics of critical thinking, as well as the seven steps you can use to implement the full critical thinking process.

Critical thinking comes from asking the right questions to come to the best conclusion possible. Strong critical thinkers analyze information from a variety of viewpoints in order to identify the best course of action.

Don’t worry if you don’t think you have strong critical thinking skills. In this article, we’ll help you build a foundation for critical thinking so you can absorb, analyze, and make informed decisions. 

What is critical thinking? 

Critical thinking is the ability to collect and analyze information to come to a conclusion. Being able to think critically is important in virtually every industry and applicable across a wide range of positions. That’s because critical thinking isn’t subject-specific—rather, it’s your ability to parse through information, data, statistics, and other details in order to identify a satisfactory solution. 

Definitions of critical thinking

Various scholars have provided definitions of critical thinking, each emphasizing different aspects of this complex cognitive process:

Michael Scriven , an American philosopher, defines critical thinking as "the intellectually disciplined process of actively and skillfully conceptualizing, applying, analyzing, synthesizing, and/or evaluating information gathered from, or generated by, observation, experience, reflection, reasoning, or communication as a guide to belief and action."

Robert Ennis , professor emeritus at the University of Illinois, describes critical thinking as "reasonable, reflective thinking focused on deciding what to believe or do."

Diane Halpern , a cognitive psychologist and former president of the American Psychological Association, defines it as "the use of cognitive skills or strategies that increase the probability of a desirable outcome."

8 essential critical thinking skills to develop

Critical thinking is essential for success in everyday life, higher education, and professional settings. The handbook "Foundation for Critical Thinking" defines it as a process of conceptualization, analysis, synthesis, and evaluation of information.

In no particular order, here are eight key critical thinking abilities that can help you excel in any situation:

1. Analytical thinking

Analytical thinking involves evaluating data from multiple sources in order to come to the best conclusions. Analytical thinking allows people to reject cognitive biases and strive to gather and analyze intricate subject matter while solving complex problems. Analytical thinkers who thrive at critical thinking can:

Identify patterns and trends in the data

Break down complex issues into manageable components

Recognize cause-and-effect relationships

Evaluate the strength of arguments and evidence

Example: A data analyst breaks down complex sales figures to identify trends and patterns that inform the company's marketing strategy.

2. Open-mindedness

Open-mindedness is the willingness to consider new ideas, arguments, and information without prejudice. This critical thinking skill helps you analyze and process information to come to an unbiased conclusion. Part of the critical thinking process is letting your personal biases go, taking information at face value and coming to a conclusion based on multiple points of view .

Open-minded critical thinkers demonstrate:

Willingness to consider alternative viewpoints

Ability to suspend judgment until sufficient evidence is gathered

Receptiveness to constructive criticism and feedback

Flexibility in updating beliefs based on new information

Example: During a product development meeting, a team leader actively considers unconventional ideas from junior members, leading to an innovative solution.

3. Problem-solving

Effective problem solving is a cornerstone of critical thinking. It requires the ability to identify issues, generate possible solutions, evaluate alternatives, and implement the best course of action. This critical thinking skill is particularly valuable in fields like project management and entrepreneurship.

Key aspects of problem-solving include:

Clearly defining the problem

Gathering relevant information

Brainstorming potential solutions

Evaluating the pros and cons of each option

Implementing and monitoring the chosen solution

Reflecting on the outcome and adjusting as necessary

Example: A high school principal uses problem-solving skills to address declining student engagement by surveying learners, consulting with higher education experts, and implementing a new curriculum that balances academic rigor with practical, real-world applications.

4. Reasoned judgment

Reasoned judgment is a key component of higher order thinking that involves making thoughtful decisions based on logical analysis of evidence and thorough consideration of alternatives. This critical thinking skill is important in both academic and professional settings. Key aspects reasoned judgment include:

Objectively gathering and analyzing information

Evaluating the credibility and relevance of evidence

Considering multiple perspectives before drawing conclusions

Making decisions based on logical inference and sound reasoning

Example: A high school science teacher uses reasoned judgment to design an experiment, carefully observing and analyzing results before drawing conclusions about the hypothesis.

5. Reflective thinking

Reflective thinking is the process of analyzing one's own thought processes, actions, and outcomes to gain deeper understanding and improve future performance. Good critical thinking requires analyzing and synthesizing information to form a coherent understanding of a problem. It's an essential critical thinking skill for continuous learning and improvement.

Key aspects of reflective thinking include:

Critically examining one's own assumptions and cognitive biases

Considering diverse viewpoints and perspectives

Synthesizing information from various experiences and sources

Applying insights to improve future decision-making and actions

Continuously evaluating and adjusting one's thinking processes

Example: A community organizer reflects on the outcomes of a recent public event, considering what worked well and what could be improved for future initiatives.

6. Communication

Strong communication skills help critical thinkers articulate ideas clearly and persuasively. Communication in the workplace is crucial for effective teamwork, leadership, and knowledge dissemination. Key aspects of communication in critical thinking include:

Clearly expressing complex ideas

Active listening and comprehension

Adapting communication styles to different audiences

Constructing and delivering persuasive arguments

Example: A manager effectively explains a new company policy to her team, addressing their concerns and ensuring everyone understands its implications.

7. Research

Critical thinkers with strong research skills gather, evaluate, and synthesize information from various sources of information. This is particularly important in academic settings and in professional fields that require continuous learning. Effective research involves:

Identifying reliable and relevant sources of information

Evaluating the credibility and bias of sources

Synthesizing information from multiple sources

Recognizing gaps in existing knowledge

Example: A journalist verifies information from multiple credible sources before publishing an article on a controversial topic.

8. Decision-making

Effective decision making is the culmination of various critical thinking skills that allow an individual to draw logical conclusions and generalizations. It involves weighing options, considering consequences, and choosing the best course of action. Key aspects of decision-making include:

Defining clear criteria for evaluation

Gathering and analyzing relevant information

Considering short-term and long-term consequences

Managing uncertainty and risk

Balancing logic and intuition

Example: A homeowner weighs the costs, benefits, and long-term implications before deciding to invest in solar panels for their house.

How to develop critical thinking skills in 7 steps

Critical thinking is a skill that you can build by following these seven steps. The seven steps to critical thinking help you ensure you’re approaching a problem from the right angle, considering every alternative, and coming to an unbiased conclusion.

First things first: When to use the 7 step critical thinking process

There’s a lot that goes into the full critical thinking process, and not every decision needs to be this thought out. Sometimes, it’s enough to put aside bias and approach a process logically. In other, more complex cases, the best way to identify the ideal outcome is to go through the entire critical thinking process. 

The seven-step critical thinking process is useful for complex decisions in areas you are less familiar with. Alternatively, the seven critical thinking steps can help you look at a problem you’re familiar with from a different angle, without any bias. 

If you need to make a less complex decision, consider another problem solving strategy instead. Decision matrices are a great way to identify the best option between different choices. Check out our article on 7 steps to creating a decision matrix .

1. Identify the problem or question

Before you put those critical thinking skills to work, you first need to identify the problem you’re solving. This step includes taking a look at the problem from a few different perspectives and asking questions like: 

What’s happening? 

Why is this happening? 

What assumptions am I making? 

At first glance, how do I think we can solve this problem? 

A big part of developing your critical thinking skills is learning how to come to unbiased conclusions. In order to do that, you first need to acknowledge the biases that you currently have. Does someone on your team think they know the answer? Are you making assumptions that aren’t necessarily true? Identifying these details helps you later on in the process. 

2. Gather relevant information

At this point, you likely have a general idea of the problem—but in order to come up with the best solution, you need to dig deeper. 

During the research process, collect information relating to the problem, including data, statistics, historical project information, team input, and more. Make sure you gather information from a variety of sources, especially if those sources go against your personal ideas about what the problem is or how to solve it.

Gathering varied information is essential for your ability to apply the critical thinking process. If you don’t get enough information, your ability to make a final decision will be skewed. Remember that critical thinking is about helping you identify the objective best conclusion. You aren’t going with your gut—you’re doing research to find the best option

3. Analyze and evaluate data

Just as it’s important to gather a variety of information, it is also important to determine how relevant the different information sources are. After all, just because there is data doesn’t mean it’s relevant. 

Once you’ve gathered all of the information, sift through the noise and identify what information is relevant and what information isn’t. Synthesizing all of this information and establishing significance helps you weigh different data sources and come to the best conclusion later on in the critical thinking process. 

To determine data relevance, ask yourself:

How reliable is this information? 

How significant is this information? 

Is this information outdated? Is it specialized in a specific field? 

4. Consider alternative points of view

One of the most useful parts of the critical thinking process is coming to a decision without bias. In order to do so, you need to take a step back from the process and challenge the assumptions you’re making. 

We all have bias—and that isn’t necessarily a bad thing. Unconscious biases (also known as cognitive biases) often serve as mental shortcuts to simplify problem solving and aid decision making. But even when biases aren’t inherently bad, you must be aware of your biases in order to put them aside when necessary. 

Before coming to a solution, ask yourself:

Am I making any assumptions about this information? 

Are there additional variables I haven’t considered? 

Have I evaluated the information from every perspective? 

Are there any viewpoints I missed?

5. Draw logical conclusions

Finally, you’re ready to come to a conclusion. To identify the best solution, draw connections between causes and effects. Use the facts you’ve gathered to evaluate the most objective conclusion. 

Keep in mind that there may be more than one solution. Often, the problems you’re facing are complex and intricate. The critical thinking process doesn’t necessarily lead to a cut-and-dry solution—instead, the process helps you understand the different variables at play so you can make an informed decision. 

6. Develop and communication solutions

Communication is a key skill for critical thinkers. It isn’t enough to think for yourself—you also need to share your conclusion with other project stakeholders. If there are multiple solutions, present them all. There may be a case where you implement one solution, then test to see if it works before implementing another solution. 

This process of communicating and sharing ideas is key in promoting critical thinking abilities within a team or organization. By encouraging open dialogue and collaborative problem-solving, you create an environment that fosters the development of critical thinking skills in others.

7. Reflect and learn from the process

The seven-step critical thinking process yields a result—and you then need to put that solution into place. After you’ve implemented your decision, evaluate whether or not it was effective. Did it solve the initial problem? What lessons—whether positive or negative—can you learn from this experience to improve your critical thinking for next time? 

By engaging in this metacognitive reflective thinking process, you're essentially teaching critical thinking skills to yourself, refining your methodology with each iteration. This reflective practice is fundamental in developing a more robust and adaptable approach to problem-solving.

Depending on how your team shares information, consider documenting lessons learned in a central source of truth. That way, team members that are making similar or related decisions in the future can understand why you made the decision you made and what the outcome was.

Critical thinking examples in the workplace

Imagine you work in user experience design (UX). Your team is focused on pricing and packaging and ensuring customers have a clear understanding of the different services your company offers. Here’s how to apply the critical thinking process in the workplace in seven steps: 

Step 1: Start by identifying the problem

Your current pricing page isn’t performing as well as you want. You’ve heard from customers that your services aren’t clear, and that the page doesn’t answer the questions they have. This page is really important for your company, since it’s where your customers sign up for your service. You and your team have a few theories about why your current page isn’t performing well, but you decide to apply the critical thinking process to ensure you come to the best decision for the page. 

Gather information about how the problem started

Part of identifying the problem includes understanding how the problem started. The pricing and packaging page is important—so when your team initially designed the page, they certainly put a lot of thought into it. Before you begin researching how to improve the page, ask yourself: 

Why did you design the pricing page the way you did? 

Which stakeholders need to be involved in the decision making process? 

Where are users getting stuck on the page?

Are any features currently working?

Step 2: Then gather information and research

In addition to understanding the history of the pricing and packaging page, it’s important to understand what works well. Part of this research means taking a look at what your competitor’s pricing pages look like. 

Ask yourself: 

How have our competitors set up their pricing pages?

Are there any pricing page best practices? 

How does color, positioning, and animation impact navigation? 

Are there any standard page layouts customers expect to see? 

Step 3: Organize and analyze information

You’ve gathered all of the information you need—now you need to organize and analyze it. What trends, if any, are you noticing? Is there any particularly relevant or important information that you have to consider? 

Step 4: Consider alternative viewpoints to reduce bias

In the case of critical thinking, it’s important to address and set bias aside as much as possible. Ask yourself: 

Is there anything I’m missing? 

Have I connected with the right stakeholders? 

Are there any other viewpoints I should consider? 

Step 5: Determine the most logical solution for your team

You now have all of the information you need to design the best pricing page. Depending on the complexity of the design, you may want to design a few options to present to a small group of customers or A/B test on the live website.

Step 6: Communicate your solution to stakeholders

Critical thinking skills can help you in every element of your life, but in the workplace, you must also involve key project stakeholders . Stakeholders help you determine next steps, like whether you’ll A/B test the page first. Depending on the complexity of the issue, consider hosting a meeting or sharing a status report to get everyone on the same page. 

Step 7: Reflect on the results

No process is complete without evaluating the results. Once the new page has been live for some time, evaluate whether it did better than the previous page. What worked? What didn’t? This also helps you make better critical decisions later on.

Tools and techniques to improve critical thinking skills

Understanding how to improve critical thinking skills has become a cornerstone of personal and professional growth in the 21st century. Recognizing the importance of critical thinking, experts across various disciplines have contributed valuable insights and methodologies. Here are some notable contributions from experts and institutions in the field:

Mind mapping: A visual approach to critical thinking skills

Mind mapping is a visual technique that helps organize and structure information. It's particularly useful for synthesizing complex ideas and identifying connections between different concepts. The benefits of mind mapping include:

Enhancing creativity by encouraging non-linear thinking

Improving memory and retention of information

Facilitating brainstorming and idea generation

Providing a clear overview of complex topics

To create a mind map:

Start with a central idea or concept.

Branch out with related sub topics or ideas.

Use colors, symbols, and images to enhance visual appeal and memorability.

Draw connections between related ideas across different branches.

Mind mapping can be particularly effective in project planning , content creation, and studying complex subjects.

The Socratic Method: Deepening critical thinking skills

The Socratic Method, named after the ancient Greek philosopher Socrates, involves asking probing questions to stimulate critical thinking and illuminate ideas. This technique is widely used in higher education to teach critical thinking. Key aspects of the Socratic Method include:

Asking open-ended questions that encourage deeper reflection

Challenging assumptions and preconceived notions

Exploring the implications and consequences of ideas

Fostering intellectual curiosity and continuous inquiry

The Socratic Method can be applied in various settings:

In education, to encourage students to think deeply about subject matter

In business, it is important to challenge team members to consider multiple points of view.

In personal development, to examine one's own beliefs and decisions

Example: A high school teacher might use the Socratic Method to guide students through a complex ethical dilemma, asking questions like "What principles are at stake here?" and "How might this decision affect different stakeholders?"

SWOT analysis: Comprehensive critical thinking skills

SWOT (Strengths, Weaknesses, Opportunities, Threats) analysis is a strategic planning tool that can be applied to critical thinking. It helps in evaluating situations from multiple angles, promoting a more thorough understanding of complex issues. The components of SWOT analysis are:

Strengths: internal positive attributes or assets

Weaknesses: internal negative attributes or limitations

Opportunities: External factors that could be beneficial

Threats: External factors that could be harmful

To conduct a SWOT analysis:

Clearly define the subject of analysis (e.g., a project, organization, or decision).

Brainstorm and list items for each category.

Analyze the interactions between different factors.

Use the analysis to inform strategy or decision-making.

Example: A startup might use SWOT analysis to evaluate its position before seeking investment, identifying its innovative technology as a strength, limited capital as a weakness, growing market demand as an opportunity, and established competitors as a threat.

Clarity: Expressing thoughts and ideas clearly and precisely

Consistency: Maintaining logical coherence in arguments and reasoning

Commitment: Dedicating oneself to ongoing learning and improvement

These skills directly improve critical thinking and strengthen overall cognitive abilities. Understanding and practicing these 5 C's is a fundamental aspect of how to develop critical thinking skills effectively.

How do you demonstrate critical thinking?

Demonstrating critical thinking involves applying your skill set in various situations. This includes analyzing problems, evaluating information sources, considering multiple perspectives, and using evidence-based reasoning. Many employers highlight these qualities in job descriptions, as they value employees who can apply critical thought to workplace challenges.

What is a real-life example of critical thinking?

A real-life critical thinking example could be making a major purchase decision, such as buying a car. Here's how you might apply critical thinking skills:

Research: Gather information about different car models, prices, and features

Analysis: Compare and contrast options based on your needs and budget

Evaluation: Assess the reliability of information sources (e.g., consumer reports, user reviews)

Questioning: Ask car dealers probing questions about warranties, maintenance costs, and resale value

Consideration of alternatives: Explore options like leasing or public transportation

Decision-making: Weigh pros and cons to make an informed choice

Reflection: After the purchase, evaluate your decision-making process for future improvement

This critical thinking example demonstrates how critical thought can be applied to everyday situations.

Critical thinking skills are incredibly valuable–among the most in-demand skills in nearly every labor market sector. They are so valuable and in demand because they are considered to be in relatively short supply. That’s because critical thinking is a whole lot harder than it looks.

Critical thinkers do not leap to conclusions. Instead, they take the time to consider various possibilities and do not become too attached to one point of view. They do not latch on to one solution. Rather, they know that most solutions are temporary and improve over time with new data. Critical thinkers are in the habit of distinguishing between reliable and unreliable sources. They carefully weigh the strengths of conflicting views and apply logical reasoning. Critical thinkers are, at once, open to the views of others and supremely independent in their judgments.

If you want to set yourself apart at your job or in the hiring process, these are the three elements of critical thinking to master.

1. Proactive Learning

Here’s why you should care about proactive learning: Of course, the more you learn, the more you will know. But there is more to it than that: All the leading research shows that the very act of learning also strengthens your mind. If you are not actively learning, your mind is weakening—just like any muscle. No matter how smart you are, if you are not actively learning, you steadily lose those smarts over time.

The best way to build strong mental muscles is the same as physical ones: exercise them regularly. That means studying information, practicing technique, and contemplating multiple competing perspectives:

• Stored knowledge is the result of studying good information.
• Stored skills are the result of practicing good technique.
• Stored wisdom is the result of contemplating multiple competing good perspectives.

“Good technique,” in the case of non-physical skills, means keeping an open mind. That means suspending judgment, questioning assumptions, and continually seeking the best new information, technique, and perspective.

2. Problem-Solving

In today’s information environment, so many answers to so many questions are available at the tip of their fingers. Many people today are simply not in the habit of truly thinking on their feet. Without a lot of experience puzzling through problems, it should be no surprise that many people are often puzzled when encountering unanticipated problems.

Here’s the thing: Usually, you don’t need to make important decisions based on your current judgment. You are much better off if you can rely on the accumulated experience of the organization in which you are working.

Ready-made solutions are just best practices captured, turned into standard operating procedures, and deployed throughout the organization to employees for use as job aids. The most common is a simple checklist:

• If A happens, do B
• If C happens, do D
• If E happens, do F

What kind of job aids do you have at your disposal to deal with recurring problems? If you already have such job aids at your disposal, how can you better use them as learning tools?

And here’s the good news: By mastering these best practices, you will get better not only at solving the specific problems anticipated but also much better at solving unanticipated problems. By implementing specific step-by-step solutions to recurring problems, you will learn a lot about good problem-solving.

3. Decision-Making

Decision-making is not the same as sheer brain power, mental capacity, or natural intelligence . It’s not a matter of accumulated knowledge or memorized information. It is more than the mastery of techniques and tools.

Good decision-making is about predicting likely outcomes–the ability to see the connections between cause and effect–to project out the consequences of one set of events and actions instead of another. The irony is that learning from the past is the only way to develop that “go forward” ability to predict the future.

But experience alone does not teach good decision-making. The key to learning from experience is paying close attention and aggressively drawing lessons from one’s experiences. If you can begin to see the patterns in causes and their effects, you can start thinking ahead with insight. Ultimately, that’s the key to better decision-making.

Critical Thinking

Critical thinking is a widely accepted educational goal. Its definition is contested, but the competing definitions can be understood as differing conceptions of the same basic concept: careful thinking directed to a goal. Conceptions differ with respect to the scope of such thinking, the type of goal, the criteria and norms for thinking carefully, and the thinking components on which they focus. Its adoption as an educational goal has been recommended on the basis of respect for students’ autonomy and preparing students for success in life and for democratic citizenship. “Critical thinkers” have the dispositions and abilities that lead them to think critically when appropriate. The abilities can be identified directly; the dispositions indirectly, by considering what factors contribute to or impede exercise of the abilities. Standardized tests have been developed to assess the degree to which a person possesses such dispositions and abilities. Educational intervention has been shown experimentally to improve them, particularly when it includes dialogue, anchored instruction, and mentoring. Controversies have arisen over the generalizability of critical thinking across domains, over alleged bias in critical thinking theories and instruction, and over the relationship of critical thinking to other types of thinking.

Use of the term ‘critical thinking’ to describe an educational goal goes back to the American philosopher John Dewey (1910), who more commonly called it ‘reflective thinking’. He defined it as

active, persistent and careful consideration of any belief or supposed form of knowledge in the light of the grounds that support it, and the further conclusions to which it tends. (Dewey 1910: 6; 1933: 9)

and identified a habit of such consideration with a scientific attitude of mind. His lengthy quotations of Francis Bacon, John Locke, and John Stuart Mill indicate that he was not the first person to propose development of a scientific attitude of mind as an educational goal.

In the 1930s, many of the schools that participated in the Eight-Year Study of the Progressive Education Association (Aikin 1942) adopted critical thinking as an educational goal, for whose achievement the study’s Evaluation Staff developed tests (Smith, Tyler, & Evaluation Staff 1942). Glaser (1941) showed experimentally that it was possible to improve the critical thinking of high school students. Bloom’s influential taxonomy of cognitive educational objectives (Bloom et al. 1956) incorporated critical thinking abilities. Ennis (1962) proposed 12 aspects of critical thinking as a basis for research on the teaching and evaluation of critical thinking ability.

Since 1980, an annual international conference in California on critical thinking and educational reform has attracted tens of thousands of educators from all levels of education and from many parts of the world. Also since 1980, the state university system in California has required all undergraduate students to take a critical thinking course. Since 1983, the Association for Informal Logic and Critical Thinking has sponsored sessions in conjunction with the divisional meetings of the American Philosophical Association (APA). In 1987, the APA’s Committee on Pre-College Philosophy commissioned a consensus statement on critical thinking for purposes of educational assessment and instruction (Facione 1990a). Researchers have developed standardized tests of critical thinking abilities and dispositions; for details, see the Supplement on Assessment . Educational jurisdictions around the world now include critical thinking in guidelines for curriculum and assessment. Political and business leaders endorse its importance.

2. Examples and Non-Examples

Before considering the definition of critical thinking, it will be helpful to have in mind some examples of critical thinking, as well as some examples of kinds of thinking that would apparently not count as critical thinking.

Dewey (1910: 68–71; 1933: 91–94) takes as paradigms of reflective thinking three class papers of students in which they describe their thinking. The examples range from the everyday to the scientific.

Transit : “The other day, when I was down town on 16th Street, a clock caught my eye. I saw that the hands pointed to 12:20. This suggested that I had an engagement at 124th Street, at one o'clock. I reasoned that as it had taken me an hour to come down on a surface car, I should probably be twenty minutes late if I returned the same way. I might save twenty minutes by a subway express. But was there a station near? If not, I might lose more than twenty minutes in looking for one. Then I thought of the elevated, and I saw there was such a line within two blocks. But where was the station? If it were several blocks above or below the street I was on, I should lose time instead of gaining it. My mind went back to the subway express as quicker than the elevated; furthermore, I remembered that it went nearer than the elevated to the part of 124th Street I wished to reach, so that time would be saved at the end of the journey. I concluded in favor of the subway, and reached my destination by one o’clock.” (Dewey 1910: 68-69; 1933: 91-92)

Ferryboat : “Projecting nearly horizontally from the upper deck of the ferryboat on which I daily cross the river is a long white pole, having a gilded ball at its tip. It suggested a flagpole when I first saw it; its color, shape, and gilded ball agreed with this idea, and these reasons seemed to justify me in this belief. But soon difficulties presented themselves. The pole was nearly horizontal, an unusual position for a flagpole; in the next place, there was no pulley, ring, or cord by which to attach a flag; finally, there were elsewhere on the boat two vertical staffs from which flags were occasionally flown. It seemed probable that the pole was not there for flag-flying.

“I then tried to imagine all possible purposes of the pole, and to consider for which of these it was best suited: (a) Possibly it was an ornament. But as all the ferryboats and even the tugboats carried poles, this hypothesis was rejected. (b) Possibly it was the terminal of a wireless telegraph. But the same considerations made this improbable. Besides, the more natural place for such a terminal would be the highest part of the boat, on top of the pilot house. (c) Its purpose might be to point out the direction in which the boat is moving.

“In support of this conclusion, I discovered that the pole was lower than the pilot house, so that the steersman could easily see it. Moreover, the tip was enough higher than the base, so that, from the pilot's position, it must appear to project far out in front of the boat. Morevoer, the pilot being near the front of the boat, he would need some such guide as to its direction. Tugboats would also need poles for such a purpose. This hypothesis was so much more probable than the others that I accepted it. I formed the conclusion that the pole was set up for the purpose of showing the pilot the direction in which the boat pointed, to enable him to steer correctly.” (Dewey 1910: 69-70; 1933: 92-93)

Bubbles : “In washing tumblers in hot soapsuds and placing them mouth downward on a plate, bubbles appeared on the outside of the mouth of the tumblers and then went inside. Why? The presence of bubbles suggests air, which I note must come from inside the tumbler. I see that the soapy water on the plate prevents escape of the air save as it may be caught in bubbles. But why should air leave the tumbler? There was no substance entering to force it out. It must have expanded. It expands by increase of heat, or by decrease of pressure, or both. Could the air have become heated after the tumbler was taken from the hot suds? Clearly not the air that was already entangled in the water. If heated air was the cause, cold air must have entered in transferring the tumblers from the suds to the plate. I test to see if this supposition is true by taking several more tumblers out. Some I shake so as to make sure of entrapping cold air in them. Some I take out holding mouth downward in order to prevent cold air from entering. Bubbles appear on the outside of every one of the former and on none of the latter. I must be right in my inference. Air from the outside must have been expanded by the heat of the tumbler, which explains the appearance of the bubbles on the outside. But why do they then go inside? Cold contracts. The tumbler cooled and also the air inside it. Tension was removed, and hence bubbles appeared inside. To be sure of this, I test by placing a cup of ice on the tumbler while the bubbles are still forming outside. They soon reverse” (Dewey 1910: 70–71; 1933: 93–94).

Dewey (1910, 1933) sprinkles his book with other examples of critical thinking. We will refer to the following.

Weather : A man on a walk notices that it has suddenly become cool, thinks that it is probably going to rain, looks up and sees a dark cloud obscuring the sun, and quickens his steps (1910: 6–10; 1933: 9–13).

Disorder : A man finds his rooms on his return to them in disorder with his belongings thrown about, thinks at first of burglary as an explanation, then thinks of mischievous children as being an alternative explanation, then looks to see whether valuables are missing, and discovers that they are (1910: 82–83; 1933: 166–168).

Typhoid : A physician diagnosing a patient whose conspicuous symptoms suggest typhoid avoids drawing a conclusion until more data are gathered by questioning the patient and by making tests (1910: 85–86; 1933: 170).

Blur : A moving blur catches our eye in the distance, we ask ourselves whether it is a cloud of whirling dust or a tree moving its branches or a man signaling to us, we think of other traits that should be found on each of those possibilities, and we look and see if those traits are found (1910: 102, 108; 1933: 121, 133).

Suction pump : In thinking about the suction pump, the scientist first notes that it will draw water only to a maximum height of 33 feet at sea level and to a lesser maximum height at higher elevations, selects for attention the differing atmospheric pressure at these elevations, sets up experiments in which the air is removed from a vessel containing water (when suction no longer works) and in which the weight of air at various levels is calculated, compares the results of reasoning about the height to which a given weight of air will allow a suction pump to raise water with the observed maximum height at different elevations, and finally assimilates the suction pump to such apparently different phenomena as the siphon and the rising of a balloon (1910: 150–153; 1933: 195–198).

Diamond : A passenger in a car driving in a diamond lane reserved for vehicles with at least one passenger notices that the diamond marks on the pavement are far apart in some places and close together in others. Why? The driver suggests that the reason may be that the diamond marks are not needed where there is a solid double line separating the diamond line from the adjoining lane, but are needed when there is a dotted single line permitting crossing into the diamond lane. Further observation confirms that the diamonds are close together when a dotted line separates the diamond lane from its neighbour, but otherwise far apart.

Rash : A woman suddenly develops a very itchy red rash on her throat and upper chest. She recently noticed a mark on the back of her right hand, but was not sure whether the mark was a rash or a scrape. She lies down in bed and thinks about what might be causing the rash and what to do about it. About two weeks before, she began taking blood pressure medication that contained a sulfa drug, and the pharmacist had warned her, in view of a previous allergic reaction to a medication containing a sulfa drug, to be on the alert for an allergic reaction; however, she had been taking the medication for two weeks with no such effect. The day before, she began using a new cream on her neck and upper chest; against the new cream as the cause was mark on the back of her hand, which had not been exposed to the cream. She began taking probiotics about a month before. She also recently started new eye drops, but she supposed that manufacturers of eye drops would be careful not to include allergy-causing components in the medication. The rash might be a heat rash, since she recently was sweating profusely from her upper body. Since she is about to go away on a short vacation, where she would not have access to her usual physician, she decides to keep taking the probiotics and using the new eye drops but to discontinue the blood pressure medication and to switch back to the old cream for her neck and upper chest. She forms a plan to consult her regular physician on her return about the blood pressure medication.

Candidate : Although Dewey included no examples of thinking directed at appraising the arguments of others, such thinking has come to be considered a kind of critical thinking. We find an example of such thinking in the performance task on the Collegiate Learning Assessment (CLA+), which its sponsoring organization describes as

a performance-based assessment that provides a measure of an institution’s contribution to the development of critical-thinking and written communication skills of its students. (Council for Aid to Education 2017)

A sample task posted on its website requires the test-taker to write a report for public distribution evaluating a fictional candidate’s policy proposals and their supporting arguments, using supplied background documents, with a recommendation on whether to endorse the candidate.

Immediate acceptance of an idea that suggests itself as a solution to a problem (e.g., a possible explanation of an event or phenomenon, an action that seems likely to produce a desired result) is “uncritical thinking, the minimum of reflection” (Dewey 1910: 13). On-going suspension of judgment in the light of doubt about a possible solution is not critical thinking (Dewey 1910: 108). Critique driven by a dogmatically held political or religious ideology is not critical thinking; thus Paulo Freire (1968 [1970]) is using the term (e.g., at 1970: 71, 81, 100, 146) in a more politically freighted sense that includes not only reflection but also revolutionary action against oppression. Derivation of a conclusion from given data using an algorithm is not critical thinking.

What is critical thinking? There are many definitions. Ennis (2016) lists 14 philosophically oriented scholarly definitions and three dictionary definitions. Following Rawls (1971), who distinguished his conception of justice from a utilitarian conception but regarded them as rival conceptions of the same concept, Ennis maintains that the 17 definitions are different conceptions of the same concept. Rawls articulated the shared concept of justice as

a characteristic set of principles for assigning basic rights and duties and for determining… the proper distribution of the benefits and burdens of social cooperation. (Rawls 1971: 5)

Bailin et al. (1999b) claim that, if one considers what sorts of thinking an educator would take not to be critical thinking and what sorts to be critical thinking, one can conclude that educators typically understand critical thinking to have at least three features.

• It is done for the purpose of making up one’s mind about what to believe or do.
• The person engaging in the thinking is trying to fulfill standards of adequacy and accuracy appropriate to the thinking.
• The thinking fulfills the relevant standards to some threshold level.

One could sum up the core concept that involves these three features by saying that critical thinking is careful goal-directed thinking. This core concept seems to apply to all the examples of critical thinking described in the previous section. As for the non-examples, their exclusion depends on construing careful thinking as excluding jumping immediately to conclusions, suspending judgment no matter how strong the evidence, reasoning from an unquestioned ideological or religious perspective, and routinely using an algorithm to answer a question.

If the core of critical thinking is careful goal-directed thinking, conceptions of it can vary according to its presumed scope, its presumed goal, one’s criteria and threshold for being careful, and the thinking component on which one focuses As to its scope, some conceptions (e.g., Dewey 1910, 1933) restrict it to constructive thinking on the basis of one’s own observations and experiments, others (e.g., Ennis 1962; Fisher & Scriven 1997; Johnson 1992) to appraisal of the products of such thinking. Ennis (1991) and Bailin et al. (1999b) take it to cover both construction and appraisal. As to its goal, some conceptions restrict it to forming a judgment (Dewey 1910, 1933; Lipman 1987; Facione 1990a). Others allow for actions as well as beliefs as the end point of a process of critical thinking (Ennis 1991; Bailin et al. 1999b). As to the criteria and threshold for being careful, definitions vary in the term used to indicate that critical thinking satisfies certain norms: “intellectually disciplined” (Scriven & Paul 1987), “reasonable” (Ennis 1991), “skillful” (Lipman 1987), “skilled” (Fisher & Scriven 1997), “careful” (Bailin & Battersby 2009). Some definitions specify these norms, referring variously to “consideration of any belief or supposed form of knowledge in the light of the grounds that support it and the further conclusions to which it tends” (Dewey 1910, 1933); “the methods of logical inquiry and reasoning” (Glaser 1941); “conceptualizing, applying, analyzing, synthesizing, and/or evaluating information gathered from, or generated by, observation, experience, reflection, reasoning, or communication” (Scriven & Paul 1987); the requirement that “it is sensitive to context, relies on criteria, and is self-correcting” (Lipman 1987); “evidential, conceptual, methodological, criteriological, or contextual considerations” (Facione 1990a); and “plus-minus considerations of the product in terms of appropriate standards (or criteria)” (Johnson 1992). Stanovich and Stanovich (2010) propose to ground the concept of critical thinking in the concept of rationality, which they understand as combining epistemic rationality (fitting one’s beliefs to the world) and instrumental rationality (optimizing goal fulfillment); a critical thinker, in their view, is someone with “a propensity to override suboptimal responses from the autonomous mind” (2010: 227). These variant specifications of norms for critical thinking are not necessarily incompatible with one another, and in any case presuppose the core notion of thinking carefully. As to the thinking component singled out, some definitions focus on suspension of judgment during the thinking (Dewey 1910; McPeck 1981), others on inquiry while judgment is suspended (Bailin & Battersby 2009), others on the resulting judgment (Facione 1990a), and still others on the subsequent emotive response (Siegel 1988).

In educational contexts, a definition of critical thinking is a “programmatic definition” (Scheffler 1960: 19). It expresses a practical program for achieving an educational goal. For this purpose, a one-sentence formulaic definition is much less useful than articulation of a critical thinking process, with criteria and standards for the kinds of thinking that the process may involve. The real educational goal is recognition, adoption and implementation by students of those criteria and standards. That adoption and implementation in turn consists in acquiring the knowledge, abilities and dispositions of a critical thinker.

Conceptions of critical thinking generally do not include moral integrity as part of the concept. Dewey, for example, took critical thinking to be the ultimate intellectual goal of education, but distinguished it from the development of social cooperation among school children, which he took to be the central moral goal. Ennis (1996, 2011) added to his previous list of critical thinking dispositions a group of dispositions to care about the dignity and worth of every person, which he described as a “correlative” (1996) disposition without which critical thinking would be less valuable and perhaps harmful. An educational program that aimed at developing critical thinking but not the correlative disposition to care about the dignity and worth of every person, he asserted, “would be deficient and perhaps dangerous” (Ennis 1996: 172).

Dewey thought that education for reflective thinking would be of value to both the individual and society; recognition in educational practice of the kinship to the scientific attitude of children’s native curiosity, fertile imagination and love of experimental inquiry “would make for individual happiness and the reduction of social waste” (Dewey 1910: iii). Schools participating in the Eight-Year Study took development of the habit of reflective thinking and skill in solving problems as a means to leading young people to understand, appreciate and live the democratic way of life characteristic of the United States (Aikin 1942: 17–18, 81). Harvey Siegel (1988: 55–61) has offered four considerations in support of adopting critical thinking as an educational ideal. (1) Respect for persons requires that schools and teachers honour students’ demands for reasons and explanations, deal with students honestly, and recognize the need to confront students’ independent judgment; these requirements concern the manner in which teachers treat students. (2) Education has the task of preparing children to be successful adults, a task that requires development of their self-sufficiency. (3) Education should initiate children into the rational traditions in such fields as history, science and mathematics. (4) Education should prepare children to become democratic citizens, which requires reasoned procedures and critical talents and attitudes. To supplement these considerations, Siegel (1988: 62–90) responds to two objections: the ideology objection that adoption of any educational ideal requires a prior ideological commitment and the indoctrination objection that cultivation of critical thinking cannot escape being a form of indoctrination.

Despite the diversity of our 11 examples, one can recognize a common pattern. Dewey analyzed it as consisting of five phases:

• suggestions , in which the mind leaps forward to a possible solution;
• an intellectualization of the difficulty or perplexity into a problem to be solved, a question for which the answer must be sought;
• the use of one suggestion after another as a leading idea, or hypothesis , to initiate and guide observation and other operations in collection of factual material;
• the mental elaboration of the idea or supposition as an idea or supposition ( reasoning , in the sense on which reasoning is a part, not the whole, of inference); and
• testing the hypothesis by overt or imaginative action. (Dewey 1933: 106–107; italics in original)

The process of reflective thinking consisting of these phases would be preceded by a perplexed, troubled or confused situation and followed by a cleared-up, unified, resolved situation (Dewey 1933: 106). The term ‘phases’ replaced the term ‘steps’ (Dewey 1910: 72), thus removing the earlier suggestion of an invariant sequence. Variants of the above analysis appeared in (Dewey 1916: 177) and (Dewey 1938: 101–119).

The variant formulations indicate the difficulty of giving a single logical analysis of such a varied process. The process of critical thinking may have a spiral pattern, with the problem being redefined in the light of obstacles to solving it as originally formulated. For example, the person in Transit might have concluded that getting to the appointment at the scheduled time was impossible and have reformulated the problem as that of rescheduling the appointment for a mutually convenient time. Further, defining a problem does not always follow after or lead immediately to an idea of a suggested solution. Nor should it do so, as Dewey himself recognized in describing the physician in Typhoid as avoiding any strong preference for this or that conclusion before getting further information (Dewey 1910: 85; 1933: 170). People with a hypothesis in mind, even one to which they have a very weak commitment, have a so-called “confirmation bias” (Nickerson 1998): they are likely to pay attention to evidence that confirms the hypothesis and to ignore evidence that counts against it or for some competing hypothesis. Detectives, intelligence agencies, and investigators of airplane accidents are well advised to gather relevant evidence systematically and to postpone even tentative adoption of an explanatory hypothesis until the collected evidence rules out with the appropriate degree of certainty all but one explanation. Dewey’s analysis of the critical thinking process can be faulted as well for requiring acceptance or rejection of a possible solution to a defined problem, with no allowance for deciding in the light of the available evidence to suspend judgment. Further, given the great variety of kinds of problems for which reflection is appropriate, there is likely to be variation in its component events. Perhaps the best way to conceptualize the critical thinking process is as a checklist whose component events can occur in a variety of orders, selectively, and more than once. These component events might include (1) noticing a difficulty, (2) defining the problem, (3) dividing the problem into manageable sub-problems, (4) formulating a variety of possible solutions to the problem or sub-problem, (5) determining what evidence is relevant to deciding among possible solutions to the problem or sub-problem, (6) devising a plan of systematic observation or experiment that will uncover the relevant evidence, (7) carrying out the plan of systematic observation or experimentation, (8) noting the results of the systematic observation or experiment, (9) gathering relevant testimony and information from others, (10) judging the credibility of testimony and information gathered from others, (11) drawing conclusions from gathered evidence and accepted testimony, and (12) accepting a solution that the evidence adequately supports (cf. Hitchcock 2017: 485).

Checklist conceptions of the process of critical thinking are open to the objection that they are too mechanical and procedural to fit the multi-dimensional and emotionally charged issues for which critical thinking is urgently needed (Paul 1984). For such issues, a more dialectical process is advocated, in which competing relevant world views are identified, their implications explored, and some sort of creative synthesis attempted.

If one considers the critical thinking process illustrated by the 11 examples, one can identify distinct kinds of mental acts and mental states that form part of it. To distinguish, label and briefly characterize these components is a useful preliminary to identifying abilities, skills, dispositions, attitudes, habits and the like that contribute causally to thinking critically. Identifying such abilities and habits is in turn a useful preliminary to setting educational goals. Setting the goals is in its turn a useful preliminary to designing strategies for helping learners to achieve the goals and to designing ways of measuring the extent to which learners have done so. Such measures provide both feedback to learners on their achievement and a basis for experimental research on the effectiveness of various strategies for educating people to think critically. Let us begin, then, by distinguishing the kinds of mental acts and mental events that can occur in a critical thinking process.

• Observing : One notices something in one’s immediate environment (sudden cooling of temperature in Weather , bubbles forming outside a glass and then going inside in Bubbles , a moving blur in the distance in Blur , a rash in Rash ). Or one notes the results of an experiment or systematic observation (valuables missing in Disorder , no suction without air pressure in Suction pump )
• Feeling : One feels puzzled or uncertain about something (how to get to an appointment on time in Transit , why the diamonds vary in frequency in Diamond ). One wants to resolve this perplexity. One feels satisfaction once one has worked out an answer (to take the subway express in Transit , diamonds closer when needed as a warning in Diamond ).
• Wondering : One formulates a question to be addressed (why bubbles form outside a tumbler taken from hot water in Bubbles , how suction pumps work in Suction pump , what caused the rash in Rash ).
• Imagining : One thinks of possible answers (bus or subway or elevated in Transit , flagpole or ornament or wireless communication aid or direction indicator in Ferryboat , allergic reaction or heat rash in Rash ).
• Inferring : One works out what would be the case if a possible answer were assumed (valuables missing if there has been a burglary in Disorder , earlier start to the rash if it is an allergic reaction to a sulfa drug in Rash ). Or one draws a conclusion once sufficient relevant evidence is gathered (take the subway in Transit , burglary in Disorder , discontinue blood pressure medication and new cream in Rash ).
• Knowledge : One uses stored knowledge of the subject-matter to generate possible answers or to infer what would be expected on the assumption of a particular answer (knowledge of a city’s public transit system in Transit , of the requirements for a flagpole in Ferryboat , of Boyle’s law in Bubbles , of allergic reactions in Rash ).
• Experimenting : One designs and carries out an experiment or a systematic observation to find out whether the results deduced from a possible answer will occur (looking at the location of the flagpole in relation to the pilot’s position in Ferryboat , putting an ice cube on top of a tumbler taken from hot water in Bubbles , measuring the height to which a suction pump will draw water at different elevations in Suction pump , noticing the frequency of diamonds when movement to or from a diamond lane is allowed in Diamond ).
• Consulting : One finds a source of information, gets the information from the source, and makes a judgment on whether to accept it. None of our 11 examples include searching for sources of information. In this respect they are unrepresentative, since most people nowadays have almost instant access to information relevant to answering any question, including many of those illustrated by the examples. However, Candidate includes the activities of extracting information from sources and evaluating its credibility.
• Identifying and analyzing arguments : One notices an argument and works out its structure and content as a preliminary to evaluating its strength. This activity is central to Candidate . It is an important part of a critical thinking process in which one surveys arguments for various positions on an issue.
• Judging : One makes a judgment on the basis of accumulated evidence and reasoning, such as the judgment in Ferryboat that the purpose of the pole is to provide direction to the pilot.
• Deciding : One makes a decision on what to do or on what policy to adopt, as in the decision in Transit to take the subway.

By definition, a person who does something voluntarily is both willing and able to do that thing at that time. Both the willingness and the ability contribute causally to the person’s action, in the sense that the voluntary action would not occur if either (or both) of these were lacking. For example, suppose that one is standing with one’s arms at one’s sides and one voluntarily lifts one’s right arm to an extended horizontal position. One would not do so if one were unable to lift one’s arm, if for example one’s right side was paralyzed as the result of a stroke. Nor would one do so if one were unwilling to lift one’s arm, if for example one were participating in a street demonstration at which a white supremacist was urging the crowd to lift their right arm in a Nazi salute and one were unwilling to express support in this way for the racist Nazi ideology. The same analysis applies to a voluntary mental process of thinking critically. It requires both willingness and ability to think critically, including willingness and ability to perform each of the mental acts that compose the process and to coordinate those acts in a sequence that is directed at resolving the initiating perplexity.

Consider willingness first. We can identify causal contributors to willingness to think critically by considering factors that would cause a person who was able to think critically about an issue nevertheless not to do so (Hamby 2014). For each factor, the opposite condition thus contributes causally to willingness to think critically on a particular occasion. For example, people who habitually jump to conclusions without considering alternatives will not think critically about issues that arise, even if they have the required abilities. The contrary condition of willingness to suspend judgment is thus a causal contributor to thinking critically.

Now consider ability. In contrast to the ability to move one’s arm, which can be completely absent because a stroke has left the arm paralyzed, the ability to think critically is a developed ability, whose absence is not a complete absence of ability to think but absence of ability to think well. We can identify the ability to think well directly, in terms of the norms and standards for good thinking. In general, to be able do well the thinking activities that can be components of a critical thinking process, one needs to know the concepts and principles that characterize their good performance, to recognize in particular cases that the concepts and principles apply, and to apply them. The knowledge, recognition and application may be procedural rather than declarative. It may be domain-specific rather than widely applicable, and in either case may need subject-matter knowledge, sometimes of a deep kind.

Reflections of the sort illustrated by the previous two paragraphs have led scholars to identify the knowledge, abilities and dispositions of a “critical thinker”, i.e., someone who thinks critically whenever it is appropriate to do so. We turn now to these three types of causal contributors to thinking critically. We start with dispositions, since arguably these are the most powerful contributors to being a critical thinker, can be fostered at an early stage of a child’s development, and are susceptible to general improvement (Glaser 1941: 175)

8. Critical Thinking Dispositions

Educational researchers use the term ‘dispositions’ broadly for the habits of mind and attitudes that contribute causally to being a critical thinker. Some writers (e.g., Paul & Elder 2006; Hamby 2014; Bailin & Battersby 2016) propose to use the term ‘virtues’ for this dimension of a critical thinker. The virtues in question, although they are virtues of character, concern the person’s ways of thinking rather than the person’s ways of behaving towards others. They are not moral virtues but intellectual virtues, of the sort articulated by Zagzebski (1996) and discussed by Turri, Alfano, and Greco (2017).

On a realistic conception, thinking dispositions or intellectual virtues are real properties of thinkers. They are general tendencies, propensities, or inclinations to think in particular ways in particular circumstances, and can be genuinely explanatory (Siegel 1999). Sceptics argue that there is no evidence for a specific mental basis for the habits of mind that contribute to thinking critically, and that it is pedagogically misleading to posit such a basis (Bailin et al. 1999a). Whatever their status, critical thinking dispositions need motivation for their initial formation in a child—motivation that may be external or internal. As children develop, the force of habit will gradually become important in sustaining the disposition (Nieto & Valenzuela 2012). Mere force of habit, however, is unlikely to sustain critical thinking dispositions. Critical thinkers must value and enjoy using their knowledge and abilities to think things through for themselves. They must be committed to, and lovers of, inquiry.

A person may have a critical thinking disposition with respect to only some kinds of issues. For example, one could be open-minded about scientific issues but not about religious issues. Similarly, one could be confident in one’s ability to reason about the theological implications of the existence of evil in the world but not in one’s ability to reason about the best design for a guided ballistic missile.

Critical thinking dispositions can usefully be divided into initiating dispositions (those that contribute causally to starting to think critically about an issue) and internal dispositions (those that contribute causally to doing a good job of thinking critically once one has started) (Facione 1990a: 25). The two categories are not mutually exclusive. For example, open-mindedness, in the sense of willingness to consider alternative points of view to one’s own, is both an initiating and an internal disposition.

Using the strategy of considering factors that would block people with the ability to think critically from doing so, we can identify as initiating dispositions for thinking critically attentiveness, a habit of inquiry, self-confidence, courage, open-mindedness, willingness to suspend judgment, trust in reason, wanting evidence for one’s beliefs, and seeking the truth. We consider briefly what each of these dispositions amounts to, in each case citing sources that acknowledge them.

• Attentiveness : One will not think critically if one fails to recognize an issue that needs to be thought through. For example, the pedestrian in Weather would not have looked up if he had not noticed that the air was suddenly cooler. To be a critical thinker, then, one needs to be habitually attentive to one’s surroundings, noticing not only what one senses but also sources of perplexity in messages received and in one’s own beliefs and attitudes (Facione 1990a: 25; Facione, Facione, & Giancarlo 2001).
• Habit of inquiry : Inquiry is effortful, and one needs an internal push to engage in it. For example, the student in Bubbles could easily have stopped at idle wondering about the cause of the bubbles rather than reasoning to a hypothesis, then designing and executing an experiment to test it. Thus willingness to think critically needs mental energy and initiative. What can supply that energy? Love of inquiry, or perhaps just a habit of inquiry. Hamby (2015) has argued that willingness to inquire is the central critical thinking virtue, one that encompasses all the others. It is recognized as a critical thinking disposition by Dewey (1910: 29; 1933: 35), Glaser (1941: 5), Ennis (1987: 12; 1991: 8), Facione (1990a: 25), Bailin et al. (1999b: 294), Halpern (1998: 452), and Facione, Facione, & Giancarlo (2001).
• Self-confidence : Lack of confidence in one’s abilities can block critical thinking. For example, if the woman in Rash lacked confidence in her ability to figure things out for herself, she might just have assumed that the rash on her chest was the allergic reaction to her medication against which the pharmacist had warned her. Thus willingness to think critically requires confidence in one’s ability to inquire (Facione 1990a: 25; Facione, Facione, & Giancarlo 2001).
• Courage : Fear of thinking for oneself can stop one from doing it. Thus willingness to think critically requires intellectual courage (Paul & Elder 2006: 16).
• Open-mindedness : A dogmatic attitude will impede thinking critically. For example, a person who adheres rigidly to a “pro-choice” position on the issue of the legal status of induced abortion is likely to be unwilling to consider seriously the issue of when in its development an unborn child acquires a moral right to life. Thus willingness to think critically requires open-mindedness, in the sense of a willingness to examine questions to which one already accepts an answer but which further evidence or reasoning might cause one to answer differently (Dewey 1933; Facione 1990a; Ennis 1991; Bailin et al. 1999b; Halpern 1998, Facione, Facione, & Giancarlo 2001). Paul (1981) emphasizes open-mindedness about alternative world-views, and recommends a dialectical approach to integrating such views as central to what he calls “strong sense” critical thinking.
• Willingness to suspend judgment : Premature closure on an initial solution will block critical thinking. Thus willingness to think critically requires a willingness to suspend judgment while alternatives are explored (Facione 1990a; Ennis 1991; Halpern 1998).
• Trust in reason : Since distrust in the processes of reasoned inquiry will dissuade one from engaging in it, trust in them is an initiating critical thinking disposition (Facione 1990a, 25; Bailin et al. 1999b: 294; Facione, Facione, & Giancarlo 2001; Paul & Elder 2006). In reaction to an allegedly exclusive emphasis on reason in critical thinking theory and pedagogy, Thayer-Bacon (2000) argues that intuition, imagination, and emotion have important roles to play in an adequate conception of critical thinking that she calls “constructive thinking”. From her point of view, critical thinking requires trust not only in reason but also in intuition, imagination, and emotion.
• Seeking the truth : If one does not care about the truth but is content to stick with one’s initial bias on an issue, then one will not think critically about it. Seeking the truth is thus an initiating critical thinking disposition (Bailin et al. 1999b: 294; Facione, Facione, & Giancarlo 2001). A disposition to seek the truth is implicit in more specific critical thinking dispositions, such as trying to be well-informed, considering seriously points of view other than one’s own, looking for alternatives, suspending judgment when the evidence is insufficient, and adopting a position when the evidence supporting it is sufficient.

Some of the initiating dispositions, such as open-mindedness and willingness to suspend judgment, are also internal critical thinking dispositions, in the sense of mental habits or attitudes that contribute causally to doing a good job of critical thinking once one starts the process. But there are many other internal critical thinking dispositions. Some of them are parasitic on one’s conception of good thinking. For example, it is constitutive of good thinking about an issue to formulate the issue clearly and to maintain focus on it. For this purpose, one needs not only the corresponding ability but also the corresponding disposition. Ennis (1991: 8) describes it as the disposition “to determine and maintain focus on the conclusion or question”, Facione (1990a: 25) as “clarity in stating the question or concern”. Other internal dispositions are motivators to continue or adjust the critical thinking process, such as willingness to persist in a complex task and willingness to abandon nonproductive strategies in an attempt to self-correct (Halpern 1998: 452). For a list of identified internal critical thinking dispositions, see the Supplement on Internal Critical Thinking Dispositions .

Some theorists postulate skills, i.e., acquired abilities, as operative in critical thinking. It is not obvious, however, that a good mental act is the exercise of a generic acquired skill. Inferring an expected time of arrival, as in Transit , has some generic components but also uses non-generic subject-matter knowledge. Bailin et al. (1999a) argue against viewing critical thinking skills as generic and discrete, on the ground that skilled performance at a critical thinking task cannot be separated from knowledge of concepts and from domain-specific principles of good thinking. Talk of skills, they concede, is unproblematic if it means merely that a person with critical thinking skills is capable of intelligent performance.

Despite such scepticism, theorists of critical thinking have listed as general contributors to critical thinking what they variously call abilities (Glaser 1941; Ennis 1962, 1991), skills (Facione 1990a; Halpern 1998) or competencies (Fisher & Scriven 1997). Amalgamating these lists would produce a confusing and chaotic cornucopia of more than 50 possible educational objectives, with only partial overlap among them. It makes sense instead to try to understand the reasons for the multiplicity and diversity, and to make a selection according to one’s own reasons for singling out abilities to be developed in a critical thinking curriculum. Two reasons for diversity among lists of critical thinking abilities are the underlying conception of critical thinking and the envisaged educational level. Appraisal-only conceptions, for example, involve a different suite of abilities than constructive-only conceptions. Some lists, such as those in (Glaser 1941), are put forward as educational objectives for secondary school students, whereas others are proposed as objectives for college students (e.g., Facione 1990a).

The abilities described in the remaining paragraphs of this section emerge from reflection on the general abilities needed to do well the thinking activities identified in section 6 as components of the critical thinking process described in section 5 . The derivation of each collection of abilities is accompanied by citation of sources that list such abilities and of standardized tests that claim to test them.

Observational abilities : Careful and accurate observation sometimes requires specialist expertise and practice, as in the case of observing birds and observing accident scenes. However, there are general abilities of noticing what one’s senses are picking up from one’s environment and of being able to articulate clearly and accurately to oneself and others what one has observed. It helps in exercising them to be able to recognize and take into account factors that make one’s observation less trustworthy, such as prior framing of the situation, inadequate time, deficient senses, poor observation conditions, and the like. It helps as well to be skilled at taking steps to make one’s observation more trustworthy, such as moving closer to get a better look, measuring something three times and taking the average, and checking what one thinks one is observing with someone else who is in a good position to observe it. It also helps to be skilled at recognizing respects in which one’s report of one’s observation involves inference rather than direct observation, so that one can then consider whether the inference is justified. These abilities come into play as well when one thinks about whether and with what degree of confidence to accept an observation report, for example in the study of history or in a criminal investigation or in assessing news reports. Observational abilities show up in some lists of critical thinking abilities (Ennis 1962: 90; Facione 1990a: 16; Ennis 1991: 9). There are items testing a person’s ability to judge the credibility of observation reports in the Cornell Critical Thinking Tests, Levels X and Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005). Norris and King (1983, 1985, 1990a, 1990b) is a test of ability to appraise observation reports.

Emotional abilities : The emotions that drive a critical thinking process are perplexity or puzzlement, a wish to resolve it, and satisfaction at achieving the desired resolution. Children experience these emotions at an early age, without being trained to do so. Education that takes critical thinking as a goal needs only to channel these emotions and to make sure not to stifle them. Collaborative critical thinking benefits from ability to recognize one’s own and others’ emotional commitments and reactions.

Questioning abilities : A critical thinking process needs transformation of an inchoate sense of perplexity into a clear question. Formulating a question well requires not building in questionable assumptions, not prejudging the issue, and using language that in context is unambiguous and precise enough (Ennis 1962: 97; 1991: 9).

Imaginative abilities : Thinking directed at finding the correct causal explanation of a general phenomenon or particular event requires an ability to imagine possible explanations. Thinking about what policy or plan of action to adopt requires generation of options and consideration of possible consequences of each option. Domain knowledge is required for such creative activity, but a general ability to imagine alternatives is helpful and can be nurtured so as to become easier, quicker, more extensive, and deeper (Dewey 1910: 34–39; 1933: 40–47). Facione (1990a) and Halpern (1998) include the ability to imagine alternatives as a critical thinking ability.

Inferential abilities : The ability to draw conclusions from given information, and to recognize with what degree of certainty one’s own or others’ conclusions follow, is universally recognized as a general critical thinking ability. All 11 examples in section 2 of this article include inferences, some from hypotheses or options (as in Transit , Ferryboat and Disorder ), others from something observed (as in Weather and Rash ). None of these inferences is formally valid. Rather, they are licensed by general, sometimes qualified substantive rules of inference (Toulmin 1958) that rest on domain knowledge—that a bus trip takes about the same time in each direction, that the terminal of a wireless telegraph would be located on the highest possible place, that sudden cooling is often followed by rain, that an allergic reaction to a sulfa drug generally shows up soon after one starts taking it. It is a matter of controversy to what extent the specialized ability to deduce conclusions from premisses using formal rules of inference is needed for critical thinking. Dewey (1933) locates logical forms in setting out the products of reflection rather than in the process of reflection. Ennis (1981a), on the other hand, maintains that a liberally-educated person should have the following abilities: to translate natural-language statements into statements using the standard logical operators, to use appropriately the language of necessary and sufficient conditions, to deal with argument forms and arguments containing symbols, to determine whether in virtue of an argument’s form its conclusion follows necessarily from its premisses, to reason with logically complex propositions, and to apply the rules and procedures of deductive logic. Inferential abilities are recognized as critical thinking abilities by Glaser (1941: 6), Facione (1990a: 9), Ennis (1991: 9), Fisher & Scriven (1997: 99, 111), and Halpern (1998: 452). Items testing inferential abilities constitute two of the five subtests of the Watson Glaser Critical Thinking Appraisal (Watson & Glaser 1980a, 1980b, 1994), two of the four sections in the Cornell Critical Thinking Test Level X (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005), three of the seven sections in the Cornell Critical Thinking Test Level Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005), 11 of the 34 items on Forms A and B of the California Critical Thinking Skills Test (Facione 1990b, 1992), and a high but variable proportion of the 25 selected-response questions in the Collegiate Learning Assessment (Council for Aid to Education 2017).

Experimenting abilities : Knowing how to design and execute an experiment is important not just in scientific research but also in everyday life, as in Rash . Dewey devoted a whole chapter of his How We Think (1910: 145–156; 1933: 190–202) to the superiority of experimentation over observation in advancing knowledge. Experimenting abilities come into play at one remove in appraising reports of scientific studies. Skill in designing and executing experiments includes the acknowledged abilities to appraise evidence (Glaser 1941: 6), to carry out experiments and to apply appropriate statistical inference techniques (Facione 1990a: 9), to judge inductions to an explanatory hypothesis (Ennis 1991: 9), and to recognize the need for an adequately large sample size (Halpern 1998). The Cornell Critical Thinking Test Level Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005) includes four items (out of 52) on experimental design. The Collegiate Learning Assessment (Council for Aid to Education 2017) makes room for appraisal of study design in both its performance task and its selected-response questions.

Consulting abilities : Skill at consulting sources of information comes into play when one seeks information to help resolve a problem, as in Candidate . Ability to find and appraise information includes ability to gather and marshal pertinent information (Glaser 1941: 6), to judge whether a statement made by an alleged authority is acceptable (Ennis 1962: 84), to plan a search for desired information (Facione 1990a: 9), and to judge the credibility of a source (Ennis 1991: 9). Ability to judge the credibility of statements is tested by 24 items (out of 76) in the Cornell Critical Thinking Test Level X (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005) and by four items (out of 52) in the Cornell Critical Thinking Test Level Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005). The College Learning Assessment’s performance task requires evaluation of whether information in documents is credible or unreliable (Council for Aid to Education 2017).

Argument analysis abilities : The ability to identify and analyze arguments contributes to the process of surveying arguments on an issue in order to form one’s own reasoned judgment, as in Candidate . The ability to detect and analyze arguments is recognized as a critical thinking skill by Facione (1990a: 7–8), Ennis (1991: 9) and Halpern (1998). Five items (out of 34) on the California Critical Thinking Skills Test (Facione 1990b, 1992) test skill at argument analysis. The College Learning Assessment (Council for Aid to Education 2017) incorporates argument analysis in its selected-response tests of critical reading and evaluation and of critiquing an argument.

Judging skills and deciding skills : Skill at judging and deciding is skill at recognizing what judgment or decision the available evidence and argument supports, and with what degree of confidence. It is thus a component of the inferential skills already discussed.

Lists and tests of critical thinking abilities often include two more abilities: identifying assumptions and constructing and evaluating definitions.

In addition to dispositions and abilities, critical thinking needs knowledge: of critical thinking concepts, of critical thinking principles, and of the subject-matter of the thinking.

We can derive a short list of concepts whose understanding contributes to critical thinking from the critical thinking abilities described in the preceding section. Observational abilities require an understanding of the difference between observation and inference. Questioning abilities require an understanding of the concepts of ambiguity and vagueness. Inferential abilities require an understanding of the difference between conclusive and defeasible inference (traditionally, between deduction and induction), as well as of the difference between necessary and sufficient conditions. Experimenting abilities require an understanding of the concepts of hypothesis, null hypothesis, assumption and prediction, as well as of the concept of statistical significance and of its difference from importance. They also require an understanding of the difference between an experiment and an observational study, and in particular of the difference between a randomized controlled trial, a prospective correlational study and a retrospective (case-control) study. Argument analysis abilities require an understanding of the concepts of argument, premiss, assumption, conclusion and counter-consideration. Additional critical thinking concepts are proposed by Bailin et al. (1999b: 293), Fisher & Scriven (1997: 105–106), and Black (2012).

According to Glaser (1941: 25), ability to think critically requires knowledge of the methods of logical inquiry and reasoning. If we review the list of abilities in the preceding section, however, we can see that some of them can be acquired and exercised merely through practice, possibly guided in an educational setting, followed by feedback. Searching intelligently for a causal explanation of some phenomenon or event requires that one consider a full range of possible causal contributors, but it seems more important that one implements this principle in one’s practice than that one is able to articulate it. What is important is “operational knowledge” of the standards and principles of good thinking (Bailin et al. 1999b: 291–293). But the development of such critical thinking abilities as designing an experiment or constructing an operational definition can benefit from learning their underlying theory. Further, explicit knowledge of quirks of human thinking seems useful as a cautionary guide. Human memory is not just fallible about details, as people learn from their own experiences of misremembering, but is so malleable that a detailed, clear and vivid recollection of an event can be a total fabrication (Loftus 2017). People seek or interpret evidence in ways that are partial to their existing beliefs and expectations, often unconscious of their “confirmation bias” (Nickerson 1998). Not only are people subject to this and other cognitive biases (Kahneman 2011), of which they are typically unaware, but it may be counter-productive for one to make oneself aware of them and try consciously to counteract them or to counteract social biases such as racial or sexual stereotypes (Kenyon & Beaulac 2014). It is helpful to be aware of these facts and of the superior effectiveness of blocking the operation of biases—for example, by making an immediate record of one’s observations, refraining from forming a preliminary explanatory hypothesis, blind refereeing, double-blind randomized trials, and blind grading of students’ work.

Critical thinking about an issue requires substantive knowledge of the domain to which the issue belongs. Critical thinking abilities are not a magic elixir that can be applied to any issue whatever by somebody who has no knowledge of the facts relevant to exploring that issue. For example, the student in Bubbles needed to know that gases do not penetrate solid objects like a glass, that air expands when heated, that the volume of an enclosed gas varies directly with its temperature and inversely with its pressure, and that hot objects will spontaneously cool down to the ambient temperature of their surroundings unless kept hot by insulation or a source of heat. Critical thinkers thus need a rich fund of subject-matter knowledge relevant to the variety of situations they encounter. This fact is recognized in the inclusion among critical thinking dispositions of a concern to become and remain generally well informed.

Experimental educational interventions, with control groups, have shown that education can improve critical thinking skills and dispositions, as measured by standardized tests. For information about these tests, see the Supplement on Assessment .

What educational methods are most effective at developing the dispositions, abilities and knowledge of a critical thinker? Abrami et al. (2015) found that in the experimental and quasi-experimental studies that they analyzed dialogue, anchored instruction, and mentoring each increased the effectiveness of the educational intervention, and that they were most effective when combined. They also found that in these studies a combination of separate instruction in critical thinking with subject-matter instruction in which students are encouraged to think critically was more effective than either by itself. However, the difference was not statistically significant; that is, it might have arisen by chance.

Most of these studies lack the longitudinal follow-up required to determine whether the observed differential improvements in critical thinking abilities or dispositions continue over time, for example until high school or college graduation. For details on studies of methods of developing critical thinking skills and dispositions, see the Supplement on Educational Methods .

12. Controversies

Scholars have denied the generalizability of critical thinking abilities across subject domains, have alleged bias in critical thinking theory and pedagogy, and have investigated the relationship of critical thinking to other kinds of thinking.

McPeck (1981) attacked the thinking skills movement of the 1970s, including the critical thinking movement. He argued that there are no general thinking skills, since thinking is always thinking about some subject-matter. It is futile, he claimed, for schools and colleges to teach thinking as if it were a separate subject. Rather, teachers should lead their pupils to become autonomous thinkers by teaching school subjects in a way that brings out their cognitive structure and that encourages and rewards discussion and argument. As some of his critics (e.g., Paul 1985; Siegel 1985) pointed out, McPeck’s central argument needs elaboration, since it has obvious counter-examples in writing and speaking, for which (up to a certain level of complexity) there are teachable general abilities even though they are always about some subject-matter. To make his argument convincing, McPeck needs to explain how thinking differs from writing and speaking in a way that does not permit useful abstraction of its components from the subject-matters with which it deals. He has not done so. Nevertheless, his position that the dispositions and abilities of a critical thinker are best developed in the context of subject-matter instruction is shared by many theorists of critical thinking, including Dewey (1910, 1933), Glaser (1941), Passmore (1980), Weinstein (1990), and Bailin et al. (1999b).

McPeck’s challenge prompted reflection on the extent to which critical thinking is subject-specific. McPeck argued for a strong subject-specificity thesis, according to which it is a conceptual truth that all critical thinking abilities are specific to a subject. (He did not however extend his subject-specificity thesis to critical thinking dispositions. In particular, he took the disposition to suspend judgment in situations of cognitive dissonance to be a general disposition.) Conceptual subject-specificity is subject to obvious counter-examples, such as the general ability to recognize confusion of necessary and sufficient conditions. A more modest thesis, also endorsed by McPeck, is epistemological subject-specificity, according to which the norms of good thinking vary from one field to another. Epistemological subject-specificity clearly holds to a certain extent; for example, the principles in accordance with which one solves a differential equation are quite different from the principles in accordance with which one determines whether a painting is a genuine Picasso. But the thesis suffers, as Ennis (1989) points out, from vagueness of the concept of a field or subject and from the obvious existence of inter-field principles, however broadly the concept of a field is construed. For example, the principles of hypothetico-deductive reasoning hold for all the varied fields in which such reasoning occurs. A third kind of subject-specificity is empirical subject-specificity, according to which as a matter of empirically observable fact a person with the abilities and dispositions of a critical thinker in one area of investigation will not necessarily have them in another area of investigation.

The thesis of empirical subject-specificity raises the general problem of transfer. If critical thinking abilities and dispositions have to be developed independently in each school subject, how are they of any use in dealing with the problems of everyday life and the political and social issues of contemporary society, most of which do not fit into the framework of a traditional school subject? Proponents of empirical subject-specificity tend to argue that transfer is more likely to occur if there is critical thinking instruction in a variety of domains, with explicit attention to dispositions and abilities that cut across domains. But evidence for this claim is scanty. There is a need for well-designed empirical studies that investigate the conditions that make transfer more likely.

It is common ground in debates about the generality or subject-specificity of critical thinking dispositions and abilities that critical thinking about any topic requires background knowledge about the topic. For example, the most sophisticated understanding of the principles of hypothetico-deductive reasoning is of no help unless accompanied by some knowledge of what might be plausible explanations of some phenomenon under investigation.

Critics have objected to bias in the theory, pedagogy and practice of critical thinking. Commentators (e.g., Alston 1995; Ennis 1998) have noted that anyone who takes a position has a bias in the neutral sense of being inclined in one direction rather than others. The critics, however, are objecting to bias in the pejorative sense of an unjustified favoring of certain ways of knowing over others, frequently alleging that the unjustly favoured ways are those of a dominant sex or culture (Bailin 1995). These ways favour:

• reinforcement of egocentric and sociocentric biases over dialectical engagement with opposing world-views (Paul 1981, 1984; Warren 1998)
• distancing from the object of inquiry over closeness to it (Martin 1992; Thayer-Bacon 1992)
• indifference to the situation of others over care for them (Martin 1992)
• orientation to thought over orientation to action (Martin 1992)
• being reasonable over caring to understand people’s ideas (Thayer-Bacon 1993)
• being neutral and objective over being embodied and situated (Thayer-Bacon 1995a)
• doubting over believing (Thayer-Bacon 1995b)
• reason over emotion, imagination and intuition (Thayer-Bacon 2000)
• solitary thinking over collaborative thinking (Thayer-Bacon 2000)
• written and spoken assignments over other forms of expression (Alston 2001)
• attention to written and spoken communications over attention to human problems (Alston 2001)
• winning debates in the public sphere over making and understanding meaning (Alston 2001)

A common thread in this smorgasbord of accusations is dissatisfaction with focusing on the logical analysis and evaluation of reasoning and arguments. While these authors acknowledge that such analysis and evaluation is part of critical thinking and should be part of its conceptualization and pedagogy, they insist that it is only a part. Paul (1981), for example, bemoans the tendency of atomistic teaching of methods of analyzing and evaluating arguments to turn students into more able sophists, adept at finding fault with positions and arguments with which they disagree but even more entrenched in the egocentric and sociocentric biases with which they began. Martin (1992) and Thayer-Bacon (1992) cite with approval the self-reported intimacy with their subject-matter of leading researchers in biology and medicine, an intimacy that conflicts with the distancing allegedly recommended in standard conceptions and pedagogy of critical thinking. Thayer-Bacon (2000) contrasts the embodied and socially embedded learning of her elementary school students in a Montessori school, who used their imagination, intuition and emotions as well as their reason, with conceptions of critical thinking as

thinking that is used to critique arguments, offer justifications, and make judgments about what are the good reasons, or the right answers. (Thayer-Bacon 2000: 127–128)

Alston (2001) reports that her students in a women’s studies class were able to see the flaws in the Cinderella myth that pervades much romantic fiction but in their own romantic relationships still acted as if all failures were the woman’s fault and still accepted the notions of love at first sight and living happily ever after. Students, she writes, should

be able to connect their intellectual critique to a more affective, somatic, and ethical account of making risky choices that have sexist, racist, classist, familial, sexual, or other consequences for themselves and those both near and far… critical thinking that reads arguments, texts, or practices merely on the surface without connections to feeling/desiring/doing or action lacks an ethical depth that should infuse the difference between mere cognitive activity and something we want to call critical thinking. (Alston 2001: 34)

Some critics portray such biases as unfair to women. Thayer-Bacon (1992), for example, has charged modern critical thinking theory with being sexist, on the ground that it separates the self from the object and causes one to lose touch with one’s inner voice, and thus stigmatizes women, who (she asserts) link self to object and listen to their inner voice. Her charge does not imply that women as a group are on average less able than men to analyze and evaluate arguments. Facione (1990c) found no difference by sex in performance on his California Critical Thinking Skills Test. Kuhn (1991: 280–281) found no difference by sex in either the disposition or the competence to engage in argumentative thinking.

The critics propose a variety of remedies for the biases that they allege. In general, they do not propose to eliminate or downplay critical thinking as an educational goal. Rather, they propose to conceptualize critical thinking differently and to change its pedagogy accordingly. Their pedagogical proposals arise logically from their objections. They can be summarized as follows:

• Focus on argument networks with dialectical exchanges reflecting contesting points of view rather than on atomic arguments, so as to develop “strong sense” critical thinking that transcends egocentric and sociocentric biases (Paul 1981, 1984).
• Foster closeness to the subject-matter and feeling connected to others in order to inform a humane democracy (Martin 1992).
• Develop “constructive thinking” as a social activity in a community of physically embodied and socially embedded inquirers with personal voices who value not only reason but also imagination, intuition and emotion (Thayer-Bacon 2000).
• In developing critical thinking in school subjects, treat as important neither skills nor dispositions but opening worlds of meaning (Alston 2001).
• Attend to the development of critical thinking dispositions as well as skills, and adopt the “critical pedagogy” practised and advocated by Freire (1968 [1970]) and hooks (1994) (Dalgleish, Girard, & Davies 2017).

A common thread in these proposals is treatment of critical thinking as a social, interactive, personally engaged activity like that of a quilting bee or a barn-raising (Thayer-Bacon 2000) rather than as an individual, solitary, distanced activity symbolized by Rodin’s The Thinker . One can get a vivid description of education with the former type of goal from the writings of bell hooks (1994, 2010). Critical thinking for her is open-minded dialectical exchange across opposing standpoints and from multiple perspectives, a conception similar to Paul’s “strong sense” critical thinking (Paul 1981). She abandons the structure of domination in the traditional classroom. In an introductory course on black women writers, for example, she assigns students to write an autobiographical paragraph about an early racial memory, then to read it aloud as the others listen, thus affirming the uniqueness and value of each voice and creating a communal awareness of the diversity of the group’s experiences (hooks 1994: 84). Her “engaged pedagogy” is thus similar to the “freedom under guidance” implemented in John Dewey’s Laboratory School of Chicago in the late 1890s and early 1900s. It incorporates the dialogue, anchored instruction, and mentoring that Abrami (2015) found to be most effective in improving critical thinking skills and dispositions.

What is the relationship of critical thinking to problem solving, decision-making, higher-order thinking, creative thinking, and other recognized types of thinking? One’s answer to this question obviously depends on how one defines the terms used in the question. If critical thinking is conceived broadly to cover any careful thinking about any topic for any purpose, then problem solving and decision making will be kinds of critical thinking, if they are done carefully. Historically, ‘critical thinking’ and ‘problem solving’ were two names for the same thing. If critical thinking is conceived more narrowly as consisting solely of appraisal of intellectual products, then it will be disjoint with problem solving and decision making, which are constructive.

Bloom’s taxonomy of educational objectives used the phrase “intellectual abilities and skills” for what had been labeled “critical thinking” by some, “reflective thinking” by Dewey and others, and “problem solving” by still others (Bloom et al. 1956: 38). Thus, the so-called “higher-order thinking skills” at the taxonomy’s top levels of analysis, synthesis and evaluation are just critical thinking skills, although they do not come with general criteria for their assessment (Ennis 1981b). The revised version of Bloom’s taxonomy (Anderson et al. 2001) likewise treats critical thinking as cutting across those types of cognitive process that involve more than remembering (Anderson et al. 2001: 269–270). For details, see the Supplement on History .

As to creative thinking, it overlaps with critical thinking (Bailin 1987, 1988). Thinking about the explanation of some phenomenon or event, as in Ferryboat , requires creative imagination in constructing plausible explanatory hypotheses. Likewise, thinking about a policy question, as in Candidate , requires creativity in coming up with options. Conversely, creativity in any field needs to be balanced by critical appraisal of the draft painting or novel or mathematical theory.
