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

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.

Writing to Think: Critical Thinking and the Writing Process

“Writing is thinking on paper.” (Zinsser, 1976, p. vii)

Google the term “critical thinking.” How many hits are there? On the day this tutorial was completed, Google found about 65,100,000 results in 0.56 seconds. That’s an impressive number, and it grows more impressively large every day. That’s because the nation’s educators, business leaders, and political representatives worry about the level of critical thinking skills among today’s students and workers.

What is Critical Thinking?

Simply put, critical thinking is sound thinking. Critical thinkers work to delve beneath the surface of sweeping generalizations, biases, clichés, and other quick observations that characterize ineffective thinking. They are willing to consider points of view different from their own, seek and study evidence and examples, root out sloppy and illogical argument, discern fact from opinion, embrace reason over emotion or preference, and change their minds when confronted with compelling reasons to do so. In sum, critical thinkers are flexible thinkers equipped to become active and effective spouses, parents, friends, consumers, employees, citizens, and leaders. Every area of life, in other words, can be positively affected by strong critical thinking.

Released in January 2011, an important study of college students over four years concluded that by graduation “large numbers [of American undergraduates] didn’t learn the critical thinking, complex reasoning and written communication skills that are widely assumed to be at the core of a college education” (Rimer, 2011, para. 1). The University designs curriculum, creates support programs, and hires faculty to help ensure you won’t be one of the students “[showing]no significant gains in . . . ‘higher order’ thinking skills” (Rimer, 2011, para. 4). One way the University works to help you build those skills is through writing projects.

Writing and Critical Thinking

Say the word “writing” and most people think of a completed publication. But say the word “writing” to writers, and they will likely think of the process of composing. Most writers would agree with novelist E. M. Forster, who wrote, “How can I know what I think until I see what I say?” (Forster, 1927, p. 99). Experienced writers know that the act of writing stimulates thinking.

Inexperienced and experienced writers have very different understandings of composition. Novice writers often make the mistake of believing they have to know what they’re going to write before they can begin writing. They often compose a thesis statement before asking questions or conducting research. In the course of their reading, they might even disregard material that counters their pre-formed ideas. This is not writing; it is recording.

In contrast, experienced writers begin with questions and work to discover many different answers before settling on those that are most convincing. They know that the act of putting words on paper or a computer screen helps them invent thought and content. Rather than trying to express what they already think, they express what the act of writing leads them to think as they put down words. More often than not, in other words, experienced writers write their way into ideas, which they then develop, revise, and refine as they go.

What has this notion of writing to do with critical thinking? Everything.

Consider the steps of the writing process: prewriting, outlining, drafting, revising, editing, seeking feedback, and publishing. These steps are not followed in a determined or strict order; instead, the effective writer knows that as they write, it may be necessary to return to an earlier step. In other words, in the process of revision, a writer may realize that the order of ideas is unclear. A new outline may help that writer re-order details. As they write, the writer considers and reconsiders the effectiveness of the work.

The writing process, then, is not just a mirror image of the thinking process: it is the thinking process. Confronted with a topic, an effective critical thinker/writer

• asks questions
• seeks answers
• evaluates evidence
• questions assumptions
• tests hypotheses
• makes inferences
• employs logic
• draws conclusions
• predicts readers’ responses
• creates order
• drafts content
• seeks others’ responses
• weighs feedback
• criticizes their own work
• revises content and structure
• seeks clarity and coherence

Example of Composition as Critical Thinking

“Good writing is fueled by unanswerable questions” (Lane, 1993, p. 15).

Imagine that you have been asked to write about a hero or heroine from history. You must explain what challenges that individual faced and how they conquered them. Now imagine that you decide to write about Rosa Parks and her role in the modern Civil Rights movement. Take a moment and survey what you already know. She refused to get up out of her seat on a bus so a White man could sit in it. She was arrested. As a result, Blacks in Montgomery protested, influencing the Montgomery Bus Boycott. Martin Luther King, Jr. took up leadership of the cause, and ultimately a movement was born.

Is that really all there is to Rosa Parks’s story? What questions might a thoughtful writer ask? Here a few:

• Why did Rosa Parks refuse to get up on that particular day?
• Was hers a spontaneous or planned act of defiance?
• Did she work? Where? Doing what?
• Had any other Black person refused to get up for a White person?
• What happened to that individual or those individuals?
• Why hadn’t that person or those persons received the publicity Parks did?
• Was Parks active in Civil Rights before that day?
• How did she learn about civil disobedience?

Even just these few questions could lead to potentially rich information.

Factual information would not be enough, however, to satisfy an assignment that asks for an interpretation of that information. The writer’s job for the assignment is to convince the reader that Parks was a heroine; in this way the writer must make an argument and support it. The writer must establish standards of heroic behavior. More questions arise:

• What is heroic action?
• What are the characteristics of someone who is heroic?
• What do heroes value and believe?
• What are the consequences of a hero’s actions?
• Why do they matter?

Now the writer has even more research and more thinking to do.

By the time they have raised questions and answered them, raised more questions and answered them, and so on, they are ready to begin writing. But even then, new ideas will arise in the course of planning and drafting, inevitably leading the writer to more research and thought, to more composition and refinement.

Ultimately, every step of the way over the course of composing a project, the writer is engaged in critical thinking because the effective writer examines the work as they develop it.

Why Writing to Think Matters

Writing practice builds critical thinking, which empowers people to “take charge of [their] own minds” so they “can take charge of [their] own lives . . . and improve them, bringing them under [their] self command and direction” (Foundation for Critical Thinking, 2020, para. 12). Writing is a way of coming to know and understand the self and the changing world, enabling individuals to make decisions that benefit themselves, others, and society at large. Your knowledge alone – of law, medicine, business, or education, for example – will not be enough to meet future challenges. You will be tested by new unexpected circumstances, and when they arise, the open-mindedness, flexibility, reasoning, discipline, and discernment you have learned through writing practice will help you meet those challenges successfully.

“If we are uncritical we shall always find what we want: we shall look for, and find confirmations” Karl Popper, cited in:  Critical Thinking  (Tom Chatfield)

Critical writing needs critical thinking. While most of this guide focuses on critical writing, it is first important to consider what we mean by criticality at university. This is because critical writing is primarily a process of evidencing and articulating your critical thinking. As such, it is really important to get the 'thinking bit' of your studies right! If you are able to demonstrate criticality in your thinking, it will make critical writing easier. 

Williams’ (2009:viii) introduces criticality at university as:

“being thoughtful, asking questions, not taking things you read (or hear) at face value. It means finding information and understanding different approaches and using them in your writing.

What is critical thinking?

Critical thinking requires you to carefully evaluate not just sources of information, but also the ideas within them and the arguments they develop. This is an essential part of being a student at university. You cannot simply believe everything you read or are told. For some people, this can feel uncomfortable as this requires you to critique published authors and notable academics. While this may feel inappropriate, it is one of the foundations of academic debate. Indeed, for any given topic or issue, there are many equally valid academic positions. To be effective in your critical thinking, you need to use both scepticism and objectivity :

Scepticism requires you to bring doubt and a questioning attitude to your academic work. In essence, you must ensure you do not automatically accept everything you hear, read or see as true (Chatfield, 2018). This requires you to  question everything you hear, read or see . This is the first step towards developing a critical approach.

Objectivity

Objectivity requires you to approach your work with a more neutral perspective . While it is not possible to take yourself out of your work, when you are engaging in critical thinking you need to acknowledge anything that influences your perspective. This is very important as without this level of self-awareness you can focus more on your opinion than developing a reasoned argument. 

Remember, you CAN criticise the experts - the University of Sussex make this point well here: Critical Thinking: Criticising the experts .

A short introduction to critical writing

Making your thinking more critical with questions

This page has so far demonstrated the importance of asking questions in all of your academic work and learning. Questions are the root of criticality. Questions engage you in active thought, requiring you to process what you are hearing, reading, seeing or experiencing against what you already know. All questions, however, are not as equally probing. Questions like 'what', 'when' and 'who' tend to be more descriptive in contrast to  questions like 'how' or 'so what' which are much more critical .

When engaging in critical thinking, you need to use a range of questions to fully consider the topic or issue you are trying to understand. Descriptive questions are great for developing your initial understanding, but you also need to consider more analytical and evaluatory questions to fully engage in critical thinking . The diagram below introduces some of the core critical questions: 

Based on: University of Plymouth

Critical questions when reading

Most of your critical thinking should be directed towards your reading of the literature. This is because the literature forms the basis of all academic writing, serving as the evidence for whatever point(s) you are trying to make. Our  Reading at University SkillsGuide  contains some useful sections which apply criticality to determining source reliability and identifying an argument. Direct links to these can be found below:

Have you ever received feedback in a piece of work saying 'be more critical' or 'not enough critical analysis' but found yourself scratching your head, wondering what that means? Dive into this bitesize workshop to discover what it is and how to do it:

University-level work requires both descriptive and critical elements. But what's the difference?

Descriptive

Being descriptive shows what you know about a topic and provides the evidence to support your arguments. It uses simpler processes like  remembering , understanding and applying . You might summarise previous research, explain concepts or describe processes.

Being critical pulls evidence together to build your arguments; what does it all mean together? It uses more complex processes: analysing ,  evaluating and creating . You might make comparisons, consider reasons and implications, justify choices or consider strengths and weaknesses.

Bloom's Taxonomy  is a useful tool to consider descriptive and critical processes:

What is critical writing?

Academic writing requires criticality; it's not enough to just describe or summarise evidence, you also need to analyse and evaluate information and use it to build your own arguments. This is where you show your own thoughts based on the evidence available, so critical writing is really important for higher grades.

Explore the key features of critical writing and see it in practice in some examples:

Introduction to critical writing [Google Slides]

While we need criticality in our writing, it's definitely possible to go further than needed. We’re aiming for that Goldilocks ‘just right’ point between not critical enough and too critical. Find out more:

Critical reading

Criticality isn't just for writing, it is also important to read critically. Reading critically helps you:

• evaluative whether sources are suitable for your assignments.
• know what you're looking for when reading.
• find the information you need quickly.

Using evidence critically

Academic writing integrates evidence from sources to create your own critical arguments.

We're not looking for a list of summaries of individual sources; ideally, the important evidence should be integrated into a cohesive whole.  What does the evidence mean altogether?  Of course, a critical argument also needs some critical analysis of this evidence.  What does it all mean in terms of your argument?

Critical language

Critical writing is going to require critical language. Different terms will give different nuance to your argument. Others will just keep things interesting! In the document below we go through some examples to help you out:

Assignment titles: critical or descriptive?

Assignment titles contain various words that show where you need to be descriptive and where you need to be critical. Explore some of the most common instructional words: 

Descriptive instructional words

define : give the precise meaning

examine : look at carefully; consider different aspects

explain : clearly describe how a process works, why a decision was made, or give other information needed to understand the topic

illustrate : explain and describe using examples

outline : give an overview of the key information, leaving out minor details

Critical instructional words

analyse : break down the information into parts, consider how parts work together

discuss : explain a topic, make comparisons, consider strengths & weaknesses, give reasons, consider implications

evaluate : assess something's worth, value or suitability for a purpose - this often leads to making a choice afterwards

justify : show the reasoning behind a choice, argument or standpoint

synthesise : bring together evidence and information to create a cohesive whole, integrate ideas or issues

Academic Writing: Critical Thinking & Writing

• Academic Writing

• Critical Thinking & Writing
• Building an argument
• Reflective Writing
• Summarising, paraphrasing and quoting

Critical Thinking

One of the most important features of studying at university is the expectation that you will engage in thinking critically about your subject area. 

Critical thinking involves asking meaningful questions concerning the information, ideas, beliefs, and arguments that you will encounter. It requires you to approach your studies with a curious, open mind, discard preconceptions, and interrogate received knowledge and established practices.

Critical thinking is key to successfully expressing your individuality as an independent learner and thinker in an academic context. It is also a valuable life skill. 

Critical thinking enables you to:

• Evaluate information, its validity and significance in a particular context.
• Analyse and interpret evidence and data in response to a line of enquiry.
• Weigh-up alternative explanations and arguments.
• Develop your own evidence-based and well-reasoned arguments.
• Develop well-informed viewpoints.
• Formulate your own independent, justifiable ideas.
• Actively engage with the wider scholarship of your academic community.

Writing Critically

Being able to demonstrate and communicate critical thinking in your written assignments through critical writing is key to achieving academic success. 

Critical writing can be distinguished from descriptive writing which is concerned with conveying information rather than interrogating information. Understanding the difference between these two styles of academic writing and when to use them is important.

The balance between descriptive writing and critical writing will vary depending on the nature of the assignment and the level of your studies. Some level of descriptive writing is generally necessary to support critical writing. More sophisticated criticality is generally required at higher levels of study with less descriptive content. You will continue to develop your critical writing skills as you progress through your course.

Descriptive Writing and Critical Writing

• Descriptive Writing
• Critical Writing
• Examples of Critical Writing

Descriptive writing demonstrates the knowledge you have of a subject, and your knowledge of what other people say about that subject.  Descriptive writing often responds to questions framed as ‘what’ , ‘where’ , ‘who’ and ‘when’ .

Descriptive writing might include the following:

• Description of what something is or what it is about (an account, facts, observable features, details): a topic, problem, situation, or context of the subject under discussion.
• Description of where it takes place (setting and context), who is involved and when it occurs. 
• Re-statement or summary of what others say about the topic.
• Background facts and information for a discussion.

Description usually comes before critical content so that the reader can understand the topic you are critically engaging with.

Critical writing requires you to apply interpretation, analysis, and evaluation to the descriptions you have provided. Critical writing often responds to questions framed as ‘how’ or ‘why’ . Often, critical writing will require you to build an argument which is supported by evidence. 

Some indicators of critical writing are:

• Investigation of positive and negative perspectives on ideas
• Supporting ideas and arguments with evidence, which might include authoritative sources, data, statistics, research, theories, and quotations
• Balanced, unbiased appraisal of arguments and counterarguments/alternative viewpoints
• Honest recognition of the limitations of an argument and supporting evidence
• Plausible, rational, convincing, and well-reasoned conclusions 

Critical writing might include the following:

• Applying an idea or theory to different situations or relate theory to practice. Does the idea work/not work in practice? Is there a factor that makes it work/not work? For example: 'Smith's (2008) theory on teamwork is effective in the workplace because it allows a diverse group of people with different skills to work effectively'.
• Justifying why a process or policy exists. For example: 'It was necessary for the nurse to check the patient's handover notes because...'
• Proposing an alternative approach to view and act on situations. For example: 'By adopting a Freirian approach, we could view the student as a collaborator in our teaching and learning'. Or: 'If we had followed the NMC guidelines we could have made the patient feel calm and relaxed during the consultation'.
• Discussion of the strengths and weaknesses of an idea/theory/policy. Why does this idea/theory/policy work? Or why does this idea not work? For example: 'Although Smith's (2008) theory on teamwork is useful for large teams, there are challenges in applying this theory to teams who work remotely'. 
• Discussion of how the idea links to other ideas in the field (synthesis). For example: 'the user experience of parks can be greatly enhanced by examining Donnelly's (2009) customer service model used in retail’.
• Discussion of how the idea compares and contrasts with other ideas/theories. For example: ‘The approach advocated by the NMC differs in comparison because of factor A and factor C’.
• Discussion of the ‘’up-to-datedness” and relevance of an idea/theory/policy (its currency). For example: 'although this approach was successful in supporting the local community, Smith's model does not accommodate the needs of a modern global economy'. 
• Evaluating an idea/theory/policy by providing evidence-informed judgment. For example: 'Therefore, May's delivery model should be discontinued as it has created significant issues for both customers and staff (Ransom, 2018)'.
• Creating new perspectives or arguments based on knowledge. For example: 'to create strong and efficient buildings, we will look to the designs provided by nature. The designs of the Sydney Opera House are based on the segments of an orange (Cook, 2019)'.

Critical thinking and writing: critical writing and argumentation.

• Critical Thinking
• Problem Solving
• Critical Reading
• Critical Writing and Argumentation
• Presenting your Sources

Common feedback from lecturers is that students' writing is too descriptive, not showing enough criticality: "too descriptive", "not supported by enough evidence", "unbalanced", "not enough critical analysis". This guide provides the foundations of critical writing along with some useful techniques to assist you in strengthening this skill. 

Key features of critical writing

Key features in critical writing include:

• Refusing to simply accept and agree with other writers - you should show criticality towards other's works and evaluate their arguments, questioning if their supporting evidence holds up, if they show any biases, whether they have considered alternative perspectives, and how their arguments fit into the wider dialogue/debate taking place in their field. 
• Presenting an argument that indicates an unbiased view supported by good evidence and fair consideration of counter-arguments that may show an alternative perspective on the subject.
• Recognizing the limitations of your evidence, argument and conclusion and therefore indicating where further research is needed.

Structuring Your Writing to Express Criticality

In order to be considered critical, academic writing must go beyond being merely descriptive. Whilst you may have some descriptive writing in your assignments to clarify terms or provide background information, it is important for the majority of your assignment to provide analysis and evaluation. 

Description :

Define clearly what you are talking about, introduce a topic.

Analysis literally means to break down something into its components to better understand it. However, there is much more to analysis: you may at times need to examine and explain how the parts fit into a whole; give reasons; compare and contrast different elements; show your understanding of relationships. Analysis is, to much extent, context and subject specific.

Here are some possible analytical questions:

• What are the constituent elements of something?
• How do the elements interact?
• What can be grouped together? What does grouping reveal?
• How does this compare and contrast with something else?
• What are the causes (factors) of something?
• What are the implications of something?
• How is this influenced by different external areas, such as the economy, society etc (e.g. SWOT, PESTEL analysis)?
• Does it happen all the time? When? Where?
• What other factors play a role? What is absent/missing?
• What other perspectives should we consider?
• What if? What are the alternatives?

With analysis you challenge the “received knowledge” and your own your assumptions.

Evaluation : 

• Identify strengths and weaknesses. 
• Assess the evidence, methodology, argument etc. presented in a source. 
• Judge the success or failure of something, its implications and/or value.
• Draw conclusions from your material, make judgments about it, and relate it to the question asked. 
• Express "mini-arguments" on the issues your raise and analyse throughout your work. (See box Your Argument.)
• Express an overarching argument on the topic of your research. (See Your Argument .)

Tip: Try to include a bit of description, analysis and evaluation in every paragraph. Writing strong paragraphs can help, as it reminds you to conclude each paragraph drawing a conclusion. However, you may also intersperse the analysis with evaluation, within the development of the paragraph. You may also find out that some parts of your work contain more description, analysis or evaluation. This could also be an effective way of structuring your critical text.

Argumentation

Presenting and defending an argument, with reasons and evidence, is a main expectation (and assessment criterion) of most essays and other forms of assessments, including dissertations. With argumentation you demonstrate critical thinking as you can draw conclusions and take a position you can defend on a topic.

What is an argument? In academic writing, an argument is the reason or set of reasons that demonstrate the validity of a thesis statement.

The view that you defend is called a  thesis statement . 

To write an effective argument, you will need to provide the following:

• Thesis statement (preferably stated in the introduction, e.g., this essay argues that...)
• Evidence in the form of literature, data, research findings etc.
• Logic: the thesis statement must be supported logically by the evidence.
• Consideration of counter-arguments
• You can present concessions to counter-arguments, but should reject their key points with your evidence/reasoning.
• Confident whenever possible
• Cautious, qualifying, hedging, when there are uncertainties and limitations

For more guidance on argumentation see page Argument and Criticality in the essay writing guide.

Module 1: Success Skills

Critical thinking, introduction, learning objectives.

• define critical thinking
• identify the role that logic plays in critical thinking
• apply critical thinking skills to problem-solving scenarios
• apply critical thinking skills to evaluation of information

Consider these thoughts about the critical thinking process, and how it applies not just to our school lives but also our personal and professional lives.

“Thinking Critically and Creatively”

Critical thinking skills are perhaps the most fundamental skills involved in making judgments and solving problems. You use them every day, and you can continue improving them.

The ability to think critically about a matter—to analyze a question, situation, or problem down to its most basic parts—is what helps us evaluate the accuracy and truthfulness of statements, claims, and information we read and hear. It is the sharp knife that, when honed, separates fact from fiction, honesty from lies, and the accurate from the misleading. We all use this skill to one degree or another almost every day. For example, we use critical thinking every day as we consider the latest consumer products and why one particular product is the best among its peers. Is it a quality product because a celebrity endorses it? Because a lot of other people may have used it? Because it is made by one company versus another? Or perhaps because it is made in one country or another? These are questions representative of critical thinking.

The academic setting demands more of us in terms of critical thinking than everyday life. It demands that we evaluate information and analyze myriad issues. It is the environment where our critical thinking skills can be the difference between success and failure. In this environment we must consider information in an analytical, critical manner. We must ask questions—What is the source of this information? Is this source an expert one and what makes it so? Are there multiple perspectives to consider on an issue? Do multiple sources agree or disagree on an issue? Does quality research substantiate information or opinion? Do I have any personal biases that may affect my consideration of this information?

It is only through purposeful, frequent, intentional questioning such as this that we can sharpen our critical thinking skills and improve as students, learners and researchers.

—Dr. Andrew Robert Baker,  Foundations of Academic Success: Words of Wisdom

Defining Critical Thinking

Thinking comes naturally. You don’t have to make it happen—it just does. But you can make it happen in different ways. For example, you can think positively or negatively. You can think with “heart” and you can think with rational judgment. You can also think strategically and analytically, and mathematically and scientifically. These are a few of multiple ways in which the mind can process thought.

What are some forms of thinking you use? When do you use them, and why?

As a college student, you are tasked with engaging and expanding your thinking skills. One of the most important of these skills is critical thinking. Critical thinking is important because it relates to nearly all tasks, situations, topics, careers, environments, challenges, and opportunities. It’s not restricted to a particular subject area.

Critical thinking is clear, reasonable, reflective thinking focused on deciding what to believe or do. It means asking probing questions like, “How do we know?” or “Is this true in every case or just in this instance?” It involves being skeptical and challenging assumptions, rather than simply memorizing facts or blindly accepting what you hear or read.

Imagine, for example, that you’re reading a history textbook. You wonder who wrote it and why, because you detect certain assumptions in the writing. You find that the author has a limited scope of research focused only on a particular group within a population. In this case, your critical thinking reveals that there are “other sides to the story.”

Who are critical thinkers, and what characteristics do they have in common? Critical thinkers are usually curious and reflective people. They like to explore and probe new areas and seek knowledge, clarification, and new solutions. They ask pertinent questions, evaluate statements and arguments, and they distinguish between facts and opinion. They are also willing to examine their own beliefs, possessing a manner of humility that allows them to admit lack of knowledge or understanding when needed. They are open to changing their mind. Perhaps most of all, they actively enjoy learning, and seeking new knowledge is a lifelong pursuit.

This may well be you!

No matter where you are on the road to being a critical thinker, you can always more fully develop your skills. Doing so will help you develop more balanced arguments, express yourself clearly, read critically, and absorb important information efficiently. Critical thinking skills will help you in any profession or any circumstance of life, from science to art to business to teaching.

Critical Thinking in Action

The following video, from Lawrence Bland, presents the major concepts and benefits of critical thinking.

Critical Thinking and Logic

Critical thinking is fundamentally a process of questioning information and data. You may question the information you read in a textbook, or you may question what a politician or a professor or a classmate says. You can also question a commonly-held belief or a new idea. With critical thinking, anything and everything is subject to question and examination.

Logic’s Relationship to Critical Thinking

The word logic comes from the Ancient Greek logike , referring to the science or art of reasoning. Using logic, a person evaluates arguments and strives to distinguish between good and bad reasoning, or between truth and falsehood. Using logic, you can evaluate ideas or claims people make, make good decisions, and form sound beliefs about the world. [1]

Questions of Logic in Critical Thinking

Let’s use a simple example of applying logic to a critical-thinking situation. In this hypothetical scenario, a man has a PhD in political science, and he works as a professor at a local college. His wife works at the college, too. They have three young children in the local school system, and their family is well known in the community.

The man is now running for political office. Are his credentials and experience sufficient for entering public office? Will he be effective in the political office? Some voters might believe that his personal life and current job, on the surface, suggest he will do well in the position, and they will vote for him.

In truth, the characteristics described don’t guarantee that the man will do a good job. The information is somewhat irrelevant. What else might you want to know? How about whether the man had already held a political office and done a good job? In this case, we want to ask, How much information is adequate in order to make a decision based on logic instead of assumptions?

The following questions, presented in Figure 1, below, are ones you may apply to formulating a logical, reasoned perspective in the above scenario or any other situation:

• What’s happening? Gather the basic information and begin to think of questions.
• Why is it important? Ask yourself why it’s significant and whether or not you agree.
• What don’t I see? Is there anything important missing?
• How do I know? Ask yourself where the information came from and how it was constructed.
• Who is saying it? What’s the position of the speaker and what is influencing them?
• What else? What if? What other ideas exist and are there other possibilities?

Problem-Solving With Critical Thinking

For most people, a typical day is filled with critical thinking and problem-solving challenges. In fact, critical thinking and problem-solving go hand-in-hand. They both refer to using knowledge, facts, and data to solve problems effectively. But with problem-solving, you are specifically identifying, selecting, and defending your solution. Below are some examples of using critical thinking to problem-solve:

• Your roommate was upset and said some unkind words to you, which put a crimp in your relationship. You try to see through the angry behaviors to determine how you might best support your roommate and help bring your relationship back to a comfortable spot.

• Your final art class project challenges you to conceptualize form in new ways. On the last day of class when students present their projects, you describe the techniques you used to fulfill the assignment. You explain why and how you selected that approach.
• Your math teacher sees that the class is not quite grasping a concept. She uses clever questioning to dispel anxiety and guide you to new understanding of the concept.
• You have a job interview for a position that you feel you are only partially qualified for, although you really want the job and you are excited about the prospects. You analyze how you will explain your skills and experiences in a way to show that you are a good match for the prospective employer.
• You are doing well in college, and most of your college and living expenses are covered. But there are some gaps between what you want and what you feel you can afford. You analyze your income, savings, and budget to better calculate what you will need to stay in college and maintain your desired level of spending.

Problem-Solving Action Checklist

Problem-solving can be an efficient and rewarding process, especially if you are organized and mindful of critical steps and strategies. Remember, too, to assume the attributes of a good critical thinker. If you are curious, reflective, knowledge-seeking, open to change, probing, organized, and ethical, your challenge or problem will be less of a hurdle, and you’ll be in a good position to find intelligent solutions.

Evaluating Information With Critical Thinking

Evaluating information can be one of the most complex tasks you will be faced with in college. But if you utilize the following four strategies, you will be well on your way to success:

• Read for understanding by using text coding
• Examine arguments
• Clarify thinking

1. Read for Understanding Using Text Coding

When you read and take notes, use the text coding strategy . Text coding is a way of tracking your thinking while reading. It entails marking the text and recording what you are thinking either in the margins or perhaps on Post-it notes. As you make connections and ask questions in response to what you read,  you monitor your comprehension and enhance your long-term understanding of the material.

With text coding, mark important arguments and key facts. Indicate where you agree and disagree or have further questions. You don’t necessarily need to read every word, but make sure you understand the concepts or the intentions behind what is written. Feel free to develop your own shorthand style when reading or taking notes. The following are a few options to consider using while coding text.

See more text coding from PBWorks and Collaborative for Teaching and Learning .

2. Examine Arguments

When you examine arguments or claims that an author, speaker, or other source is making, your goal is to identify and examine the hard facts. You can use the spectrum of authority strategy for this purpose. The spectrum of authority strategy assists you in identifying the “hot” end of an argument—feelings, beliefs, cultural influences, and societal influences—and the “cold” end of an argument—scientific influences. The following video explains this strategy.

3. Clarify Thinking

When you use critical thinking to evaluate information, you need to clarify your thinking to yourself and likely to others. Doing this well is mainly a process of asking and answering probing questions, such as the logic questions discussed earlier. Design your questions to fit your needs, but be sure to cover adequate ground. What is the purpose? What question are we trying to answer? What point of view is being expressed? What assumptions are we or others making? What are the facts and data we know, and how do we know them? What are the concepts we’re working with? What are the conclusions, and do they make sense? What are the implications?

4. Cultivate “Habits of Mind”

“Habits of mind” are the personal commitments, values, and standards you have about the principle of good thinking. Consider your intellectual commitments, values, and standards. Do you approach problems with an open mind, a respect for truth, and an inquiring attitude? Some good habits to have when thinking critically are being receptive to having your opinions changed, having respect for others, being independent and not accepting something is true until you’ve had the time to examine the available evidence, being fair-minded, having respect for a reason, having an inquiring mind, not making assumptions, and always, especially, questioning your own conclusions—in other words, developing an intellectual work ethic. Try to work these qualities into your daily life.

Critical thinking

Advice and resources to help you develop your critical voice.

Developing critical thinking skills is essential to your success at University and beyond.  We all need to be critical thinkers to help us navigate our way through an information-rich world. 

Whatever your discipline, you will engage with a wide variety of sources of information and evidence.  You will develop the skills to make judgements about this evidence to form your own views and to present your views clearly.

One of the most common types of feedback received by students is that their work is ‘too descriptive’.  This usually means that they have just stated what others have said and have not reflected critically on the material.  They have not evaluated the evidence and constructed an argument.

What is critical thinking?

Critical thinking is the art of making clear, reasoned judgements based on interpreting, understanding, applying and synthesising evidence gathered from observation, reading and experimentation. Burns, T., & Sinfield, S. (2016)  Essential Study Skills: The Complete Guide to Success at University (4th ed.) London: SAGE, p94.

Being critical does not just mean finding fault.  It means assessing evidence from a variety of sources and making reasoned conclusions.  As a result of your analysis you may decide that a particular piece of evidence is not robust, or that you disagree with the conclusion, but you should be able to state why you have come to this view and incorporate this into a bigger picture of the literature.

Being critical goes beyond describing what you have heard in lectures or what you have read.  It involves synthesising, analysing and evaluating what you have learned to develop your own argument or position.

Critical thinking is important in all subjects and disciplines – in science and engineering, as well as the arts and humanities.  The types of evidence used to develop arguments may be very different but the processes and techniques are similar.  Critical thinking is required for both undergraduate and postgraduate levels of study.

What, where, when, who, why, how?

Purposeful reading can help with critical thinking because it encourages you to read actively rather than passively.  When you read, ask yourself questions about what you are reading and make notes to record your views.  Ask questions like:

• What is the main point of this paper/ article/ paragraph/ report/ blog?
• Who wrote it?
• Why was it written?
• When was it written?
• Has the context changed since it was written?
• Is the evidence presented robust?
• How did the authors come to their conclusions?
• Do you agree with the conclusions?
• What does this add to our knowledge?
• Why is it useful?

Our web page covering Reading at university includes a handout to help you develop your own critical reading form and a suggested reading notes record sheet.  These resources will help you record your thoughts after you read, which will help you to construct your argument. 

Reading at university

Developing an argument

Being a university student is about learning how to think, not what to think.  Critical thinking shapes your own values and attitudes through a process of deliberating, debating and persuasion.   Through developing your critical thinking you can move on from simply disagreeing to constructively assessing alternatives by building on doubts.

There are several key stages involved in developing your ideas and constructing an argument.  You might like to use a form to help you think about the features of critical thinking and to break down the stages of developing your argument.

Features of critical thinking (pdf)

Features of critical thinking (Word rtf)

Our webpage on Academic writing includes a useful handout ‘Building an argument as you go’.

Academic writing

You should also consider the language you will use to introduce a range of viewpoints and to evaluate the various sources of evidence.  This will help your reader to follow your argument.  To get you started, the University of Manchester's Academic Phrasebank has a useful section on Being Critical. 

Academic Phrasebank

Developing your critical thinking

Set yourself some tasks to help develop your critical thinking skills.  Discuss material presented in lectures or from resource lists with your peers.  Set up a critical reading group or use an online discussion forum.  Think about a point you would like to make during discussions in tutorials and be prepared to back up your argument with evidence.

Recent News

critical thinking , in educational theory, mode of cognition using deliberative reasoning and impartial scrutiny of information to arrive at a possible solution to a problem. From the perspective of educators, critical thinking encompasses both a set of logical skills that can be taught and a disposition toward reflective open inquiry that can be cultivated . The term critical thinking was coined by American philosopher and educator John Dewey in the book How We Think (1910) and was adopted by the progressive education movement as a core instructional goal that offered a dynamic modern alternative to traditional educational methods such as rote memorization.

Critical thinking is characterized by a broad set of related skills usually including the abilities to

• break down a problem into its constituent parts to reveal its underlying logic and assumptions
• recognize and account for one’s own biases in judgment and experience
• collect and assess relevant evidence from either personal observations and experimentation or by gathering external information
• adjust and reevaluate one’s own thinking in response to what one has learned
• form a reasoned assessment in order to propose a solution to a problem or a more accurate understanding of the topic at hand

Theorists have noted that such skills are only valuable insofar as a person is inclined to use them. Consequently, they emphasize that certain habits of mind are necessary components of critical thinking. This disposition may include curiosity, open-mindedness, self-awareness, empathy , and persistence.

Although there is a generally accepted set of qualities that are associated with critical thinking, scholarly writing about the term has highlighted disagreements over its exact definition and whether and how it differs from related concepts such as problem solving . In addition, some theorists have insisted that critical thinking be regarded and valued as a process and not as a goal-oriented skill set to be used to solve problems. Critical-thinking theory has also been accused of reflecting patriarchal assumptions about knowledge and ways of knowing that are inherently biased against women.

Dewey, who also used the term reflective thinking , connected critical thinking to a tradition of rational inquiry associated with modern science . From the turn of the 20th century, he and others working in the overlapping fields of psychology , philosophy , and educational theory sought to rigorously apply the scientific method to understand and define the process of thinking. They conceived critical thinking to be related to the scientific method but more open, flexible, and self-correcting; instead of a recipe or a series of steps, critical thinking would be a wider set of skills, patterns, and strategies that allow someone to reason through an intellectual topic, constantly reassessing assumptions and potential explanations in order to arrive at a sound judgment and understanding.

In the progressive education movement in the United States , critical thinking was seen as a crucial component of raising citizens in a democratic society. Instead of imparting a particular series of lessons or teaching only canonical subject matter, theorists thought that teachers should train students in how to think. As critical thinkers, such students would be equipped to be productive and engaged citizens who could cooperate and rationally overcome differences inherent in a pluralistic society.

Beginning in the 1970s and ’80s, critical thinking as a key outcome of school and university curriculum leapt to the forefront of U.S. education policy. In an atmosphere of renewed Cold War competition and amid reports of declining U.S. test scores, there were growing fears that the quality of education in the United States was falling and that students were unprepared. In response, a concerted effort was made to systematically define curriculum goals and implement standardized testing regimens , and critical-thinking skills were frequently included as a crucially important outcome of a successful education. A notable event in this movement was the release of the 1980 report of the Rockefeller Commission on the Humanities that called for the U.S. Department of Education to include critical thinking on its list of “basic skills.” Three years later the California State University system implemented a policy that required every undergraduate student to complete a course in critical thinking.

Critical thinking continued to be put forward as a central goal of education in the early 21st century. Its ubiquity in the language of education policy and in such guidelines as the Common Core State Standards in the United States generated some criticism that the concept itself was both overused and ill-defined. In addition, an argument was made by teachers, theorists, and others that educators were not being adequately trained to teach critical thinking.

1 – Critical Thinking

Since ancient times, the concept of critical thinking has been associated with persuasive communication, usually in the form of speeches, scholarly texts, and literature.

Today, there are many vehicles for information and ideas, but the elements of critical thinking in a university context still bear strong influences from early scholarly writing and oration.

Definition of Critical Thinking

“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.”

Source: https://louisville.edu/ideastoaction/about/criticalthinking/what

Critical thinking may seem very abstract in  definitions such as the one above, but it is, above all,  an action . One source says critical thinking “is about being an active learner rather than a passive recipient of information” ( Skills You Need)   Most college curricula are designed to develop critical thinking.

“Critical thinkers rigorously question ideas and assumptions rather than accepting them at face value … They will always seek to determine whether the ideas, arguments, and findings represent the entire picture and are open to the possibility that they do not. It is more than the accumulation of facts, it is a way of thinking.”

                                                                                                                                   ( Source: Skills You Need )

In her article, “Why Are Critical Thinking Skills Necessary for Academics?,” journalist Jen Saunders  says, “universities concern the ways in which people research and write; their members are responsible for maintaining the foundational principles of truth and knowledge within the folds of scholarship, and permit scholars to grasp and comprehend academic subjects at levels of expertise.” ( https://classroom.synonym.com/ )

Saunders provides this information on the specific ways that critical thinking is important in  college-level work:

• Critical thinking supplies the foundation of high-quality academic writing.
• Peer awareness is an element of critical thinking in that it helps students understand and communicate with those who have different experiences, opinions, and perspectives.
• Critical thinking are necessary for passing some exams (e.g.,  essay answer, a series of multiple-choice questions to test comprehension, and especially situations where students must look for context clues or decipher word elements).
• When students are required to defend a thesis or dissertation, they need to be able to anticipate questions and respond on the spot to those asked by committee members.

Author and master teacher Michael Stratford (Demand Media), in his article, “What Are the Key Ideas for Critical Thinking Skills?”,  and the website, Skills You Need, note that someone with critical thinking skills can:

• Interpret data – becoming aware of all of the parts of an argument, such as point of view, audience, and thesis as well as reasoning through moral dilemmas
• Analyze and synthesize –  the ability to break down data into individual parts and reassemble them to create something original
• Infer and answer :  the ability to explain a problem with an inference, or educated guess. This requires knowing the difference between explaining by inference or by assumptions based on previous ideas
• Make Connections between ideas from varied sources
• Recognize, build, and appraise arguments put forth by others and determine their importance and relevance through objective evaluation
• Spot inconsistencies and errors in reasoning
• Approach problems consistently and systematically
• Reflect on the justification of one’s own assumptions, beliefs, and values

Indeed.com ., a service for finding jobs and polishing a resume, provides the following information about critical thinking. Their website offers five types of skills are important:

Five Important Critical Thinking Skills

Observation.

Observational skills are important for critical thinking because they help you to notice opportunities, problems, and solutions.  Eventually, good observers can predict  or anticipate problems or issues because their experience widens when they get in the habit of close observation. It is necessary to train yourself to pay close attention to details.

After you have spotted and identified a problem from your observation, your analytical skills become important: You must determine what part of a text or media is important and which parts are not. In other words,  gathering and evaluating sources of information that may support or depart from your text or media. This may involve a search for balanced research reports or scholarly work, and asking good questions about the text or media to make sure it is accurate and objective.

Now that you have gathered information or data, you must now interpret it and find a solution or resolution.  Even though the information you have may be incomplete, just make an “educated guess,” rather than a quick conclusion.  Look for clues (images, symbolism, data charts, or reports) that will help you analyze a situation, so you can evaluate the text or situation and come to a measured conclusion.

COMMUNICATION

In the context of critical thinking, this means engaging or initiating discussions, particularly on difficult issues or questions, especially when you face an audience that you know disagrees with your position. Use your communication skills to persuade them. Active listening, remaining calm, and showing respect are very important elements of communicating with an audience.

PROBLEM SOLVING

The problem-solving part of critical thinking involves applying or executing a conclusion or solution. You will want to choose the best, so this requires a strong understanding of your topic or goal, as well as some idea of how others have handled similar situations.

Essential “Critical” Vocabulary

[Source:  ( https://www.espressoenglish.net/difference-between-criticize-criticism-critique-critic-and-critical/]

Now let’s examine the many ways the word “critical” is used in various academic contents. You might be familiar with movie reviews or customer reviews on products in which a critic offers comments.  Below are some reviews of a long-standing Chinese restaurant in Columbus, Hunan Lion:

• The restaurant is over priced. You pay for the atmosphere. Ordered the beef and oriental veggies and to be honest it was onions and 3 pieces of broccoli. The meat was fatty and that is the worst. Typically the food is good but last night it wasn’t.
• 35 years of incredible food. By far the best Chinese restaurant in Columbus. If you want to have a great experience, without a doubt go there, you will love it.
• We ordered take out 10/01/2020. Food was TERRIBLE! The Crab Rangoon…well it’s not crab and I’m not sure of the texture it had going on but it was disgusting! The entire order of food after 1 bite went in the trash! I will certainly spread the word DO NOT ORDER FOOD from this restaurant! They are expensive and you are wasting your money. The girl at the cash register surpasses RUDE.
• The food and service were fantastic! We were in on Christmas day, and despite being busy, they did a magnificent job. We will definitely be back!

These reviews were voluntary; nevertheless, the writers of them are considered “critics,” because what they are really offering is judgment.

In a professional or academic setting, critics do much more than give a strong opinion. Whether they offer positive or negative comments, they all try to do so as objectively as possible. In other words, they avoid Personal Bias, meaning they try not to rely exclusively on their personal experiences, but rather they include influences from people, environments, cultures, values, stereotypes, and beliefs.

It is worth noting that all of these influences are part of being human. Part of critical thinking, however, means acknowledging the impact your own biases may have on the questions you ask or your interpreting of material; then, learn to overcome these evaluations. You must be like a judge in a courtroom:  you have to try to be fair and leave your own feeling out of the situation.

Activity #1:, inference exercise, harper’s is the oldest general-interest monthly magazine in the u.s. it emphasizes excellent writing and unique and varied perspectives. one of its most celebrated features is the “harper’s index,” which is a collection of random statistics about  politics, business, human behavior, social trends, research findings, and so forth. the reader is left alone to make sense of a fact by using inferences and background knowledge., below are some statistics from “harper’s index.” it is up to you to decide what each statistic suggests. something surprising mysterious what could explain its significance.

Choose a few of the facts below and write a response for each in which you raise questions , offer a possible explanation , or propose a tentative theory to explain the fact, or its significance.  Consider what the statistic suggests beyond what is written. Your response should be your own opinion , without consulting any internet resources or others.

Example:    Percentage increase last year in UFO sightings nationwide:   16% Source: [ July 2021 • Source: National UFO Reporting Center (Davenport,Wash.)] Response: Is this a large or small increase? Maybe the  increase is due to the recent U.S. government’s release of a file on unidentified flying objects (UFOs), or, what they call, “Unidentified Aerial Phenomena.” Maybe people feel like they can admit to seeing such phenomena since the government now acknowledges their existence? In the recent past, perhaps people would be laughed at or stigmatized if they claimed to see a UFO because the government and general public believed the idea of “alien life forms”  was ridiculous.

Percentage by which the unemployment rate of recently graduated U.S. physics majors exceeds that of art history majors:  60%

ACTIVITY #2 – LINKING FACTS

Sometimes the “Harper’s Index” features pairs of statistics.  It is up to you to decide what the pair, seen together, suggests. Select a couple of the pairs below and write down questions you may have, or possible explanations that tell why the pair might be significant.  Consider what the statistic suggests beyond what is written. What you write should be your own opinion , without consulting any internet resources or others.

Type your response below each set:

Movie Reviews

One of the most familiar types of criticism we encounter is a movie review,  a short description of a film and the reviewer’s opinion about it. When you watch a movie on Netflix, for example, you can see the number of stars (1-5) given by those who have watched and rated the movie. Professional reviewers usually try to give a formal, balanced account of a movie, meaning they usually provide a summary and point out some positive and negative points about a film. Amateur critics, however, can write whatever they like – all positive, all negative, or a combination.

Amateur film critiques can be found in many places; the movie review site, IMDB , is one of the most popular, with a user-generated rating feature.  Another popular site is Rotten Tomatoes, which uses a unique ‘tomato meter’ to rate movies: a green tomato means fresh while red means rotten. You can also view the individual ratings given by critics. It has more than 50,000 movies in its database. And finally, another good source of movie reviews is Metacritic , which offers a collection of reviews from various sources.

Let’s look at this review by professional movie critic Roger Ebert ( https://www.rogerebert.com/

In “Top Gun: Maverick,” a sequel to “ Top Gun, ” an admiral refers to navy aviator Pete Mitchell (Tom Cruise)—call sign “ Maverick ”—as “the fastest man alive.” Truth be told, our fearless and ever-handsome action hero earns both appraisals and applause.  Indeed, Cruise’s consistent commitment to Hollywood showmanship deserves the same level of respect usually reserved for the fully-method actors such as Daniel Day-Lewis . Even if you somehow overlook the fact that Cruise is one of our most gifted and versatile dramatic and comedic actors with movies like “ Mission Impossible , ”  “ Born on the Fourth of July ,” “ Magnolia ,” “ Tropic Thunder ,” and “ Collateral ” on his CV, you will never forget why you show up to a Tom Cruise movie.

Director Joseph Kosinski allows the leading actor to be exactly what he is—a star—while upping the emotional and dramatic stakes of the first Top Gun (1986) with a healthy dose of nostalgia.  In this Top Gun sequel, we find Maverick in a role on the fringes of the US Navy, working as a test pilot. You won’t be surprised that soon enough, he gets called on a one-last-job type of mission as a teacher to a group of recent training graduates. Their assignment is just as obscure and politically cuckoo as it was in the first movie. There is an unnamed enemy—let’s called it Russia because it’s probably Russia—some targets that need to be destroyed, a flight plan that sounds nuts, and a scheme that will require all successful Top Gun recruits to fly at dangerously low altitudes. But can it be done?

In a different package, all the proud fist-shaking seen in “Top Gun: Maverick” could have been borderline insufferable, but fortunately Kosinski seems to understand exactly what kind of movie he is asked to navigate. In his hands, the tone of “Maverick” strikes a fine balance between good-humored vanity and half-serious self-deprecation, complete with plenty of emotional moments that catch one off-guard.

In some sense, what this movie takes most seriously are concepts like friendship, loyalty, romance, and okay, bromance.  Still, the action sequences are likewise the breathtaking stars of “Maverick.” Reportedly, all the flying scenes were shot in actual U.S. Navy F/A-18s, for which the cast had to be trained. Equally worthy of that big screen is the emotional strokes of “Maverick” that pack an unexpected punch. Sure, you might be prepared for a second sky-dance with “Maverick,” but perhaps not one that might require a tissue or two in its final stretch.

ACTIVITY #3 – BEING A CRITIC

Analyze the film review above.  Does the reviewer give the movie a strongly positive or negative review? A mildly positive or negative review? A balanced review? How can you tell?  Support your opinion by identifying words, phases, and/or comparisons that directly or indirectly are positive, negative, or neutral.

ACTIVITY #4 – WRITE A MOVIE REVIEW

Select a movie to review. Choose one you either love or hate. (If it evokes emotions, it’s usually easier to review.) You may choose any movie, but for this assignment, don’t choose a film that might upset your target audience – your instructor and classmates. A movie review can be long or short.  Usually a simple outline of the plot and a sentence or two about the general setting in which it takes place will be sufficient, then add your opinion and analysis. The opinion section should be the main focus of your review. Don’t get too detailed. Your instructor will determine the word limit of this assignment.

Suggestions:

Do a web search to find information about the film: is it based on real-life events or is it fiction?

Find some information about the director and his/her/their style.

Look for information about the cast, the budget, the filming location, and where the idea for the film’s story came from. In other words, why did the producers want to make the movie?

Be sure to keep notes on where you find each piece of information – its source.  Most of the facts about movies are considered common knowledge, so they don’t have to be included in your review.

Avoid reading other reviews. They might influence your opinion, and that kind of information needs to be cited in a review.

When you are watching the film make notes of important scenes or details, symbolism, or the performances of the characters. You may want to analyze these in detail later. Again, keep notes on the source of the information you find.

Don’t give away the ending! Remember, reviews help readers decide whether or not to watch the movie. No spoilers!

Suggested Steps:

Write an introduction where you include all the basic information so that the film can be easily identified. Note the name, the director, main cast, and the characters in the story, along with the year it was made. Briefly provide the main idea of the film.

Write the main body. Analyze the story, the acting, and the director’s style. Discuss anything you would have done differently, a technique that was successful, or dialogue that was important. In other words, here is where you convey your opinion and the reasons for it. You may choose to analyze in detail one scene from the film that made an impression on you, or you may focus on an actor’s performance, or the film’s setting, music, light, character development, or dialogu

Make a conclusion. Search for several reviews of the film. Include how the film was rated by others. You will need to include information about where you found the information. Then, give your own opinion and your recommendation. You can end with a reason the audience might enjoy it or a reason you do not recommend it. Include a summary of the reasons you recommend or do not recommend it.

Critical Thinking: The Parent of Good Writing

Table of contents, instantly boost critical thinking in writing with these 7 questions, what is critical thinking.

Critical thinking  is the process of identifying and solving problems by gathering information, analyzing and evaluating evidence, discovering patterns, and reasoning logically. Critical thinking in writing means asking the right questions and questioning the old, no-longer-obvious answers. It means, in the end, finding solutions that are effective and efficient—and, often, new.

Critical thinking in writing is itself critical.

Let’s say that you ask one of your employees to write a recommendation report. In this report, she is to consider whether your company should change the vendor who provides the paper for your copying machines, printers, and paper publications. The report will recommend either staying with the old vendor or choosing a new one.

How should this writer proceed? That’s where critical thinking comes in.

The first thing we recommend is that the report writer consider two basic questions:

• Who will read the report?
• What is the purpose of the report?

If the only answers the writer can come up with are “my boss” and “to help my boss choose a paper vendor,” she’s not thinking critically. For one thing, it’s likely that the report will have many readers, including the CEO, the CFO, the COO, the Chief Procurement Officer, and maybe even some department heads who use a lot of paper.

The purpose of the report may likewise be a bit more complex: it may be used, for example, not just to help in the paper-buying decision, but also as a model for future recommendation reports about other vendors, and its recommendation will certainly influence the work of many others in the workplace (anyone, for example, who will have to make copies with cheap but inferior paper, if that’s the recommendation).

And, of course, another  purpose  of the document is to make the writer’s supervisor appreciate her reliability, thoroughness, and intelligence.

Ask the following 7 questions to strengthen and boost critical thinking in writing projects.

• What information should be included?  Cost and quality of paper, of course, but what about payment schedules, customer service, warranties, vendors’ histories and reputations, recycling strategies, and so on? What information is relevant, and what isn’t?
• What sources of information should the writer consult?  The Internet? Vendors’ sales staffs? Fellow employees? The opinions of other companies like the writer’s own?
• What level of technical sophistication should the report assume about its readers?  For example, can the writer assume that her readers will understand the difference between, say, 20- weight/96-bright paper and 24-weight/92-bright paper?
• What’s the best way to present information?  Should pricing information, for example, be presented in paragraph form, in charts, or in tables? Should testimonials from other companies about potential vendors be presented in bulleted lists or in paragraphs?
• How should the report be organized?  Much like code needs to be ordered to execute the right way, or an engineering design needs its component parts to fit together just right to work right, a written document relies on its organization to communicate information effectively.
• How should it be designed?  Words are foundational, but they’re not the only element of any communication. The design – including layout, formatting, and visual elements – can serve to strengthen, reinforce, and contextualize the writing.
• What tone and level of language sophistication should the document display?  This, in turn, depends on the audience. What will they understand, respect, and respond to?

These can be challenging questions, and only someone practiced in thinking critically knows to raise and answer such questions.

You may also notice that  not a single one  of these questions says anything about subject-verb agreement, active verbs, parallel structure, sentence fragments, or commas.

It’s true that proper grammar and punctuation, and an effective style, are important in any document; but far more important is the critical thinking that goes into it. The best grammar and the most stylish writing in the world are not of much use if the content and design of a document are not appropriate to the task—if they don’t make the document  persuasive and usable  for its  audience and purpose .

And that comes back to critical thinking.

Anyone who can apply critical thinking in writing can learn to write well.

It’s a good bet that many, if not most, of your employees already know how to think critically. How can we be so sure of this? Because the one skill necessary to do any complex job is also the one skill central to writing well: The ability to think critically. If they couldn’t do it, they couldn’t do their jobs!

And that means almost anyone can learn to write well.

Writing is not some mystery that only those with some rare magical talent can unravel. Given some basic direction, they can learn to apply their critical-thinking skills to their writing projects just as they do to all their other responsibilities. Once your employees understand that they already have the one important skill they need to write well, you’ll find that, when you ask them to produce documents for you, they will work more efficiently, effectively, and confidently.

With training, any employee can learn to apply his or her critical-thinking skills to writing. overall, your employees should understand that they already have the one skill central to writing well: the ability to analyze a problem and come up with an effective solution.

One final note : Studies show that critical thinking informs all good writing , and, perhaps surprisingly, that  the act of writing improves one’s ability to think critically .

What Is Critical Thinking? | Definition & Examples

Published on 25 September 2022 by Eoghan Ryan .

Critical thinking is the ability to effectively analyse information and form a judgement.

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, frequently asked questions.

Critical thinking is important for making judgements about sources of information and forming your own arguments. It emphasises 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 an academic context, critical thinking can help you to determine whether a source:

• Is free from research bias
• Provides evidence to support its 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.

The only proofreading tool specialized in correcting academic writing

The academic proofreading tool has been trained on 1000s of academic texts and by native English editors. Making it the most accurate and reliable proofreading tool for students.

Correct my document today

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 analyse 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 summarise it?
• When did they say this? Is the source current?
• Where is the information published? Is it an academic article? Is it a blog? A newspaper article?
• 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

Critical Thinking and Decision-Making: What is Critical Thinking?

Lesson 1: what is critical thinking, what is critical thinking.

Critical thinking is a term that gets thrown around a lot. You've probably heard it used often throughout the years whether it was in school, at work, or in everyday conversation. But when you stop to think about it, what exactly is critical thinking and how do you do it ?

Watch the video below to learn more about critical thinking.

Simply put, critical thinking is the act of deliberately analyzing information so that you can make better judgements and decisions . It involves using things like logic, reasoning, and creativity, to draw conclusions and generally understand things better.

This may sound like a pretty broad definition, and that's because critical thinking is a broad skill that can be applied to so many different situations. You can use it to prepare for a job interview, manage your time better, make decisions about purchasing things, and so much more.

The process

As humans, we are constantly thinking . It's something we can't turn off. But not all of it is critical thinking. No one thinks critically 100% of the time... that would be pretty exhausting! Instead, it's an intentional process , something that we consciously use when we're presented with difficult problems or important decisions.

Improving your critical thinking

In order to become a better critical thinker, it's important to ask questions when you're presented with a problem or decision, before jumping to any conclusions. You can start with simple ones like What do I currently know? and How do I know this? These can help to give you a better idea of what you're working with and, in some cases, simplify more complex issues.  

Real-world applications

Let's take a look at how we can use critical thinking to evaluate online information . Say a friend of yours posts a news article on social media and you're drawn to its headline. If you were to use your everyday automatic thinking, you might accept it as fact and move on. But if you were thinking critically, you would first analyze the available information and ask some questions :

• What's the source of this article?
• Is the headline potentially misleading?
• What are my friend's general beliefs?
• Do their beliefs inform why they might have shared this?

After analyzing all of this information, you can draw a conclusion about whether or not you think the article is trustworthy.

Critical thinking has a wide range of real-world applications . It can help you to make better decisions, become more hireable, and generally better understand the world around you.

• B.A., English, State University of New York

Critical thinking is the process of independently analyzing, synthesizing, and evaluating information as a guide to behavior and beliefs.

The American Philosophical Association has defined critical thinking as "the process of purposeful, self-regulatory judgment. The process gives reasoned consideration to evidence , contexts , conceptualizations, methods, and criteria" (1990). Critical thinking is sometimes broadly defined as "thinking about thinking."

Critical thinking skills include the ability to interpret, verify, and reason, all of which involve applying the principles of logic . The process of using critical thinking to guide writing is called critical writing .

Observations

• " Critical Thinking is essential as a tool of inquiry. As such, Critical Thinking is a liberating force in education and a powerful resource in one’s personal and civic life. While not synonymous with good thinking, Critical Thinking is a pervasive and self-rectifying human phenomenon. The ideal critical thinker is habitually inquisitive, well-informed, trustful of reason, open-minded, flexible, fair-minded in evaluation, honest in facing personal biases, prudent in making judgments, willing to reconsider, clear about issues, orderly in complex matters, diligent in seeking relevant information, reasonable in the selection of criteria, focused in inquiry, and persistent in seeking results which are as precise as the subject and the circumstances of inquiry permit." (American Philosophical Association, "Consensus Statement Regarding Critical Thinking," 1990)
• Thought and Language "In order to understand reasoning [...], it is necessary to pay careful attention to the relationship between thought and language . The relationship seems to be straightforward: thought is expressed in and through language. But this claim, while true, is an oversimplification. People often fail to say what they mean. Everyone has had the experience of having their \ misunderstood by others. And we all use words not merely to express our thoughts but also to shape them. Developing our critical thinking skills, therefore, requires an understanding of the ways in which words can (and often fail to) express our thoughts." (William Hughes and Jonathan Lavery, Critical Thinking: An Introduction to the Basic Skills , 4th ed. Broadview, 2004)
• Dispositions That Foster or Impede Critical thinking "Dispositions that foster critical thinking include [a] facility in perceiving irony , ambiguity , and multiplicity of meanings or points of view; the development of open-mindedness, autonomous thought, and reciprocity (Piaget's term for the ability to empathize with other individuals, social groups, nationalities, ideologies, etc.). Dispositions that act as impediments to critical thinking include defense mechanisms (such as absolutism or primary certitude, denial, projection), culturally conditioned assumptions, authoritarianism, egocentrism, and ethnocentrism, rationalization, compartmentalization, stereotyping and prejudice." (Donald Lazere, "Invention, Critical Thinking, and the Analysis of Political Rhetoric." Perspectives on Rhetorical Invention , ed. by Janet M. Atwill and Janice M. Lauer. University of Tennessee Press, 2002)
• Critical Thinking and Composing - "[T]he most intensive and demanding tool for eliciting sustained critical thought is a well-designed writing assignment on a subject matter problem. The underlying premise is that writing is closely linked with thinking and that in presenting students with significant problems to write about—and in creating an environment that demands their best writing—we can promote their general cognitive and intellectual growth. When we make students struggle with their writing, we are making them struggle with thought itself. Emphasizing writing and critical thinking , therefore, generally increases the academic rigor of a course. Often the struggle of writing, linked as it is to the struggle of thinking and to the growth of a person's intellectual powers, awakens students to the real nature of learning." (John C. Bean,  Engaging Ideas: The Professor's Guide to Integrating Writing, Critical Thinking, and Active Learning in the Classroom , 2nd ed. Wiley, 2011) - "Finding a fresh approach to a writing assignment means that you must see the subject without the blinders of preconception. When people expect to see a thing in a certain way, it usually appears that way, whether or not that is its true image. Similarly, thinking based on prefabricated ideas produces writing that says nothing new, that offers nothing important to the reader. As a writer, you have a responsibility to go beyond the expected views and present your subject so that the reader sees it with fresh eyes. . . . [C]ritical thinking is a fairly systematic method of defining a problem and synthesizing knowledge about it, thereby creating the perspective you need to develop new ideas. . . . " Classical rhetoricians used a series of three questions to help focus an argument . Today these questions can still help writers understand the topic about which they are writing. An sit? (Is the problem a fact?); Quid sit (What is the definition of the problem?); and Quale sit? (What kind of problem is it?). By asking these questions, writers see their subject from many new angles before they begin to narrow the focus to one particular aspect." (Kristin R. Woolever, About Writing: A Rhetoric for Advanced Writers . Wadsworth, 1991)
