Dictionary Definition of 'hypothesis'

An educated guess or a proposed explanation for a phenomenon or a pattern of observations. "The experiment yielded results that supported the initial hypothesis."

Detailed Meaning of 'hypothesis'

It is a statement that can be tested through scientific experimentation or further observation. In scientific research, a hypothesis is used as a starting point for an investigation, and it serves as a basis for designing experiments and collecting data to either support or disprove it. A hypothesis typically consists of two parts: the independent variable, which is the factor being tested, and the dependent variable, which is the effect that is being observed. The hypothesis states the expected relationship between the two variables. For example, if a scientist wants to test the effect of a new drug on blood pressure, the independent variable would be the drug and the dependent variable would be the blood pressure. The hypothesis in this case would be "The new drug will lower blood pressure" A hypothesis is a crucial step in the scientific method as it guides the research and helps to focus on a specific question or problem. The results of the research and experimentation can support or disprove the hypothesis, and it can lead to new discoveries and knowledge. In summary, a hypothesis is an educated guess or proposed explanation for a phenomenon or a pattern of observations, it's a statement that can be tested through scientific experimentation or further observation, it's a crucial step in the scientific method that guides the research and helps to focus on a specific question or problem.

History and Etymology of 'hypothesis'

The noun 'hypothesis' draws its linguistic lineage from the combination of two ancient Greek elements. The first part, 'hypo,' originates from the Greek word 'hupo,' meaning 'under' or 'beneath.' The second component, 'thesis,' derives from 'tithēmi,' meaning 'to place' or 'to put forth.' In the context of scientific inquiry and philosophical discourse, the term 'hypothesis' embodies the notion of putting forth an educated guess or proposition that lies beneath the surface of empirical observation. It signifies a preliminary and testable explanation for a phenomenon or a pattern of observations. Thus, the etymology of 'hypothesis' underscores its foundational role in the systematic process of scientific inquiry, where ideas are posited as a starting point for further investigation and analysis.

Frequently Asked Questions

A hypothesis is a tentative statement about the relationship between two or more  variables. It is a specific, testable prediction about what you expect to happen in a study.

One hypothesis example would be a study designed to look at the relationship between sleep deprivation and test performance might have a hypothesis that states: "This study is designed to assess the hypothesis that sleep-deprived people will perform worse on a test than individuals who are not sleep-deprived."

This article explores how a hypothesis is used in psychology research, how to write a good hypothesis, and the different types of hypotheses you might use.

The Hypothesis in the Scientific Method

In the scientific method , whether it involves research in psychology, biology, or some other area, a hypothesis represents what the researchers think will happen in an experiment. The scientific method involves the following steps:

• Forming a question
• Performing background research
• Creating a hypothesis
• Designing an experiment
• Collecting data
• Analyzing the results
• Drawing conclusions
• Communicating the results

The hypothesis is a prediction, but it involves more than a guess. Most of the time, the hypothesis begins with a question which is then explored through background research. It is only at this point that researchers begin to develop a testable hypothesis. Unless you are creating an exploratory study, your hypothesis should always explain what you  expect  to happen.

In a study exploring the effects of a particular drug, the hypothesis might be that researchers expect the drug to have some type of effect on the symptoms of a specific illness. In psychology, the hypothesis might focus on how a certain aspect of the environment might influence a particular behavior.

Remember, a hypothesis does not have to be correct. While the hypothesis predicts what the researchers expect to see, the goal of the research is to determine whether this guess is right or wrong. When conducting an experiment, researchers might explore a number of factors to determine which ones might contribute to the ultimate outcome.

In many cases, researchers may find that the results of an experiment  do not  support the original hypothesis. When writing up these results, the researchers might suggest other options that should be explored in future studies.

In many cases, researchers might draw a hypothesis from a specific theory or build on previous research. For example, prior research has shown that stress can impact the immune system. So a researcher might hypothesize: "People with high-stress levels will be more likely to contract a common cold after being exposed to the virus than people who have low-stress levels."

In other instances, researchers might look at commonly held beliefs or folk wisdom. "Birds of a feather flock together" is one example of folk wisdom that a psychologist might try to investigate. The researcher might pose a specific hypothesis that "People tend to select romantic partners who are similar to them in interests and educational level."

Elements of a Good Hypothesis

So how do you write a good hypothesis? When trying to come up with a hypothesis for your research or experiments, ask yourself the following questions:

• Is your hypothesis based on your research on a topic?
• Can your hypothesis be tested?
• Does your hypothesis include independent and dependent variables?

Before you come up with a specific hypothesis, spend some time doing background research. Once you have completed a literature review, start thinking about potential questions you still have. Pay attention to the discussion section in the  journal articles you read . Many authors will suggest questions that still need to be explored.

To form a hypothesis, you should take these steps:

• Collect as many observations about a topic or problem as you can.
• Evaluate these observations and look for possible causes of the problem.
• Create a list of possible explanations that you might want to explore.
• After you have developed some possible hypotheses, think of ways that you could confirm or disprove each hypothesis through experimentation. This is known as falsifiability.

In the scientific method ,  falsifiability is an important part of any valid hypothesis.   In order to test a claim scientifically, it must be possible that the claim could be proven false.

Students sometimes confuse the idea of falsifiability with the idea that it means that something is false, which is not the case. What falsifiability means is that  if  something was false, then it is possible to demonstrate that it is false.

One of the hallmarks of pseudoscience is that it makes claims that cannot be refuted or proven false.

A variable is a factor or element that can be changed and manipulated in ways that are observable and measurable. However, the researcher must also define how the variable will be manipulated and measured in the study.

For example, a researcher might operationally define the variable " test anxiety " as the results of a self-report measure of anxiety experienced during an exam. A "study habits" variable might be defined by the amount of studying that actually occurs as measured by time.

These precise descriptions are important because many things can be measured in a number of different ways. One of the basic principles of any type of scientific research is that the results must be replicable.   By clearly detailing the specifics of how the variables were measured and manipulated, other researchers can better understand the results and repeat the study if needed.

Some variables are more difficult than others to define. How would you operationally define a variable such as aggression ? For obvious ethical reasons, researchers cannot create a situation in which a person behaves aggressively toward others.

In order to measure this variable, the researcher must devise a measurement that assesses aggressive behavior without harming other people. In this situation, the researcher might utilize a simulated task to measure aggressiveness.

Hypothesis Checklist

• Does your hypothesis focus on something that you can actually test?
• Does your hypothesis include both an independent and dependent variable?
• Can you manipulate the variables?
• Can your hypothesis be tested without violating ethical standards?

The hypothesis you use will depend on what you are investigating and hoping to find. Some of the main types of hypotheses that you might use include:

• Simple hypothesis : This type of hypothesis suggests that there is a relationship between one independent variable and one dependent variable.
• Complex hypothesis : This type of hypothesis suggests a relationship between three or more variables, such as two independent variables and a dependent variable.
• Null hypothesis : This hypothesis suggests no relationship exists between two or more variables.
• Alternative hypothesis : This hypothesis states the opposite of the null hypothesis.
• Statistical hypothesis : This hypothesis uses statistical analysis to evaluate a representative sample of the population and then generalizes the findings to the larger group.
• Logical hypothesis : This hypothesis assumes a relationship between variables without collecting data or evidence.

A hypothesis often follows a basic format of "If {this happens} then {this will happen}." One way to structure your hypothesis is to describe what will happen to the  dependent variable  if you change the  independent variable .

The basic format might be: "If {these changes are made to a certain independent variable}, then we will observe {a change in a specific dependent variable}."

A few examples of simple hypotheses:

• "Students who eat breakfast will perform better on a math exam than students who do not eat breakfast."
• Complex hypothesis: "Students who experience test anxiety before an English exam will get lower scores than students who do not experience test anxiety."​
• "Motorists who talk on the phone while driving will be more likely to make errors on a driving course than those who do not talk on the phone."

Examples of a complex hypothesis include:

• "People with high-sugar diets and sedentary activity levels are more likely to develop depression."
• "Younger people who are regularly exposed to green, outdoor areas have better subjective well-being than older adults who have limited exposure to green spaces."

Examples of a null hypothesis include:

• "Children who receive a new reading intervention will have scores different than students who do not receive the intervention."
• "There will be no difference in scores on a memory recall task between children and adults."

Examples of an alternative hypothesis:

• "Children who receive a new reading intervention will perform better than students who did not receive the intervention."
• "Adults will perform better on a memory task than children." 

Collecting Data on Your Hypothesis

Once a researcher has formed a testable hypothesis, the next step is to select a research design and start collecting data. The research method depends largely on exactly what they are studying. There are two basic types of research methods: descriptive research and experimental research.

Descriptive Research Methods

Descriptive research such as  case studies ,  naturalistic observations , and surveys are often used when it would be impossible or difficult to  conduct an experiment . These methods are best used to describe different aspects of a behavior or psychological phenomenon.

Once a researcher has collected data using descriptive methods, a correlational study can then be used to look at how the variables are related. This type of research method might be used to investigate a hypothesis that is difficult to test experimentally.

Experimental Research Methods

Experimental methods  are used to demonstrate causal relationships between variables. In an experiment, the researcher systematically manipulates a variable of interest (known as the independent variable) and measures the effect on another variable (known as the dependent variable).

Unlike correlational studies, which can only be used to determine if there is a relationship between two variables, experimental methods can be used to determine the actual nature of the relationship—whether changes in one variable actually  cause  another to change.

A Word From Verywell

The hypothesis is a critical part of any scientific exploration. It represents what researchers expect to find in a study or experiment. In situations where the hypothesis is unsupported by the research, the research still has value. Such research helps us better understand how different aspects of the natural world relate to one another. It also helps us develop new hypotheses that can then be tested in the future.

Some examples of how to write a hypothesis include:

• "Staying up late will lead to worse test performance the next day."
• "People who consume one apple each day will visit the doctor fewer times each year."
• "Breaking study sessions up into three 20-minute sessions will lead to better test results than a single 60-minute study session."

The four parts of a hypothesis are:

• The research question
• The independent variable (IV)
• The dependent variable (DV)
• The proposed relationship between the IV and DV

A research hypothesis, in its plural form “hypotheses,” is a specific, testable prediction about the anticipated results of a study, established at its outset. It is a key component of the scientific method .

Hypotheses connect theory to data and guide the research process towards expanding scientific understanding

Some key points about hypotheses:

• A hypothesis expresses an expected pattern or relationship. It connects the variables under investigation.
• It is stated in clear, precise terms before any data collection or analysis occurs. This makes the hypothesis testable.
• A hypothesis must be falsifiable. It should be possible, even if unlikely in practice, to collect data that disconfirms rather than supports the hypothesis.
• Hypotheses guide research. Scientists design studies to explicitly evaluate hypotheses about how nature works.
• For a hypothesis to be valid, it must be testable against empirical evidence. The evidence can then confirm or disprove the testable predictions.
• Hypotheses are informed by background knowledge and observation, but go beyond what is already known to propose an explanation of how or why something occurs.

Predictions typically arise from a thorough knowledge of the research literature, curiosity about real-world problems or implications, and integrating this to advance theory. They build on existing literature while providing new insight.

Types of Research Hypotheses

Alternative hypothesis.

The research hypothesis is often called the alternative or experimental hypothesis in experimental research.

It typically suggests a potential relationship between two key variables: the independent variable, which the researcher manipulates, and the dependent variable, which is measured based on those changes.

The alternative hypothesis states a relationship exists between the two variables being studied (one variable affects the other).

A hypothesis is a testable statement or prediction about the relationship between two or more variables. It is a key component of the scientific method. Some key points about hypotheses:

• Important hypotheses lead to predictions that can be tested empirically. The evidence can then confirm or disprove the testable predictions.

In summary, a hypothesis is a precise, testable statement of what researchers expect to happen in a study and why. Hypotheses connect theory to data and guide the research process towards expanding scientific understanding.

An experimental hypothesis predicts what change(s) will occur in the dependent variable when the independent variable is manipulated.

It states that the results are not due to chance and are significant in supporting the theory being investigated.

The alternative hypothesis can be directional, indicating a specific direction of the effect, or non-directional, suggesting a difference without specifying its nature. It’s what researchers aim to support or demonstrate through their study.

Null Hypothesis

The null hypothesis states no relationship exists between the two variables being studied (one variable does not affect the other). There will be no changes in the dependent variable due to manipulating the independent variable.

It states results are due to chance and are not significant in supporting the idea being investigated.

The null hypothesis, positing no effect or relationship, is a foundational contrast to the research hypothesis in scientific inquiry. It establishes a baseline for statistical testing, promoting objectivity by initiating research from a neutral stance.

Many statistical methods are tailored to test the null hypothesis, determining the likelihood of observed results if no true effect exists.

This dual-hypothesis approach provides clarity, ensuring that research intentions are explicit, and fosters consistency across scientific studies, enhancing the standardization and interpretability of research outcomes.

Nondirectional Hypothesis

A non-directional hypothesis, also known as a two-tailed hypothesis, predicts that there is a difference or relationship between two variables but does not specify the direction of this relationship.

It merely indicates that a change or effect will occur without predicting which group will have higher or lower values.

For example, “There is a difference in performance between Group A and Group B” is a non-directional hypothesis.

Directional Hypothesis

A directional (one-tailed) hypothesis predicts the nature of the effect of the independent variable on the dependent variable. It predicts in which direction the change will take place. (i.e., greater, smaller, less, more)

It specifies whether one variable is greater, lesser, or different from another, rather than just indicating that there’s a difference without specifying its nature.

For example, “Exercise increases weight loss” is a directional hypothesis.

Falsifiability

The Falsification Principle, proposed by Karl Popper , is a way of demarcating science from non-science. It suggests that for a theory or hypothesis to be considered scientific, it must be testable and irrefutable.

Falsifiability emphasizes that scientific claims shouldn’t just be confirmable but should also have the potential to be proven wrong.

It means that there should exist some potential evidence or experiment that could prove the proposition false.

However many confirming instances exist for a theory, it only takes one counter observation to falsify it. For example, the hypothesis that “all swans are white,” can be falsified by observing a black swan.

For Popper, science should attempt to disprove a theory rather than attempt to continually provide evidence to support a research hypothesis.

Can a Hypothesis be Proven?

Hypotheses make probabilistic predictions. They state the expected outcome if a particular relationship exists. However, a study result supporting a hypothesis does not definitively prove it is true.

All studies have limitations. There may be unknown confounding factors or issues that limit the certainty of conclusions. Additional studies may yield different results.

In science, hypotheses can realistically only be supported with some degree of confidence, not proven. The process of science is to incrementally accumulate evidence for and against hypothesized relationships in an ongoing pursuit of better models and explanations that best fit the empirical data. But hypotheses remain open to revision and rejection if that is where the evidence leads.

• Disproving a hypothesis is definitive. Solid disconfirmatory evidence will falsify a hypothesis and require altering or discarding it based on the evidence.
• However, confirming evidence is always open to revision. Other explanations may account for the same results, and additional or contradictory evidence may emerge over time.

We can never 100% prove the alternative hypothesis. Instead, we see if we can disprove, or reject the null hypothesis.

If we reject the null hypothesis, this doesn’t mean that our alternative hypothesis is correct but does support the alternative/experimental hypothesis.

Upon analysis of the results, an alternative hypothesis can be rejected or supported, but it can never be proven to be correct. We must avoid any reference to results proving a theory as this implies 100% certainty, and there is always a chance that evidence may exist which could refute a theory.

How to Write a Hypothesis

• Identify variables . The researcher manipulates the independent variable and the dependent variable is the measured outcome.
• Operationalized the variables being investigated . Operationalization of a hypothesis refers to the process of making the variables physically measurable or testable, e.g. if you are about to study aggression, you might count the number of punches given by participants.
• Decide on a direction for your prediction . If there is evidence in the literature to support a specific effect of the independent variable on the dependent variable, write a directional (one-tailed) hypothesis. If there are limited or ambiguous findings in the literature regarding the effect of the independent variable on the dependent variable, write a non-directional (two-tailed) hypothesis.
• Make it Testable : Ensure your hypothesis can be tested through experimentation or observation. It should be possible to prove it false (principle of falsifiability).
• Clear & concise language . A strong hypothesis is concise (typically one to two sentences long), and formulated using clear and straightforward language, ensuring it’s easily understood and testable.

Consider a hypothesis many teachers might subscribe to: students work better on Monday morning than on Friday afternoon (IV=Day, DV= Standard of work).

Now, if we decide to study this by giving the same group of students a lesson on a Monday morning and a Friday afternoon and then measuring their immediate recall of the material covered in each session, we would end up with the following:

• The alternative hypothesis states that students will recall significantly more information on a Monday morning than on a Friday afternoon.
• The null hypothesis states that there will be no significant difference in the amount recalled on a Monday morning compared to a Friday afternoon. Any difference will be due to chance or confounding factors.

More Examples

• Memory : Participants exposed to classical music during study sessions will recall more items from a list than those who studied in silence.
• Social Psychology : Individuals who frequently engage in social media use will report higher levels of perceived social isolation compared to those who use it infrequently.
• Developmental Psychology : Children who engage in regular imaginative play have better problem-solving skills than those who don’t.
• Clinical Psychology : Cognitive-behavioral therapy will be more effective in reducing symptoms of anxiety over a 6-month period compared to traditional talk therapy.
• Cognitive Psychology : Individuals who multitask between various electronic devices will have shorter attention spans on focused tasks than those who single-task.

How to Write a Strong Hypothesis | Steps & Examples

Published on May 6, 2022 by Shona McCombes . Revised on November 20, 2023.

A hypothesis is a statement that can be tested by scientific research. If you want to test a relationship between two or more variables, you need to write hypotheses before you start your experiment or data collection .

Example: Hypothesis

Daily apple consumption leads to fewer doctor’s visits.

A hypothesis states your predictions about what your research will find. It is a tentative answer to your research question that has not yet been tested. For some research projects, you might have to write several hypotheses that address different aspects of your research question.

A hypothesis is not just a guess – it should be based on existing theories and knowledge. It also has to be testable, which means you can support or refute it through scientific research methods (such as experiments, observations and statistical analysis of data).

Variables in hypotheses

Hypotheses propose a relationship between two or more types of variables .

• An independent variable is something the researcher changes or controls.
• A dependent variable is something the researcher observes and measures.

If there are any control variables , extraneous variables , or confounding variables , be sure to jot those down as you go to minimize the chances that research bias  will affect your results.

In this example, the independent variable is exposure to the sun – the assumed cause . The dependent variable is the level of happiness – the assumed effect .

Step 1. ask a question.

Writing a hypothesis begins with a research question that you want to answer. The question should be focused, specific, and researchable within the constraints of your project.

Step 2. Do some preliminary research

Your initial answer to the question should be based on what is already known about the topic. Look for theories and previous studies to help you form educated assumptions about what your research will find.

At this stage, you might construct a conceptual framework to ensure that you’re embarking on a relevant topic . This can also help you identify which variables you will study and what you think the relationships are between them. Sometimes, you’ll have to operationalize more complex constructs.

Step 3. Formulate your hypothesis

Now you should have some idea of what you expect to find. Write your initial answer to the question in a clear, concise sentence.

4. Refine your hypothesis

You need to make sure your hypothesis is specific and testable. There are various ways of phrasing a hypothesis, but all the terms you use should have clear definitions, and the hypothesis should contain:

• The relevant variables
• The specific group being studied
• The predicted outcome of the experiment or analysis

5. Phrase your hypothesis in three ways

To identify the variables, you can write a simple prediction in  if…then form. The first part of the sentence states the independent variable and the second part states the dependent variable.

In academic research, hypotheses are more commonly phrased in terms of correlations or effects, where you directly state the predicted relationship between variables.

If you are comparing two groups, the hypothesis can state what difference you expect to find between them.

6. Write a null hypothesis

If your research involves statistical hypothesis testing , you will also have to write a null hypothesis . The null hypothesis is the default position that there is no association between the variables. The null hypothesis is written as H 0 , while the alternative hypothesis is H 1 or H a .

• H 0 : The number of lectures attended by first-year students has no effect on their final exam scores.
• H 1 : The number of lectures attended by first-year students has a positive effect on their final exam scores.

A hypothesis is not just a guess — it should be based on existing theories and knowledge. It also has to be testable, which means you can support or refute it through scientific research methods (such as experiments, observations and statistical analysis of data).

Null and alternative hypotheses are used in statistical hypothesis testing . The null hypothesis of a test always predicts no effect or no relationship between variables, while the alternative hypothesis states your research prediction of an effect or relationship.

Hypothesis testing is a formal procedure for investigating our ideas about the world using statistics. It is used by scientists to test specific predictions, called hypotheses , by calculating how likely it is that a pattern or relationship between variables could have arisen by chance.

Utah coach says her team had to switch hotels after racist attacks during NCAA Tournament

University of Utah’s women’s basketball coach said her team was the target of a series of “racial hate crimes” after arriving in Idaho for the NCAA Tournament last week. The incidents prompted the team to change hotels for the sake of their safety, she said. 

Utah coach Lynne Roberts told reporters that the team of Black, white and Latina athletes experienced several incidents Thursday night after arriving in the Spokane area for the tournament where they faced Gonzaga University. Roberts didn’t go into detail about the incidents, but said they were concerning enough to request that they be moved from their hotel in Coeur d’Alene, Idaho, to a location closer to Spokane. 

“Racism is real and it happens and it’s awful,” Roberts told reporters on Monday. “For our players, whether they are white, Black, green, whatever — no one knew how to handle it. And it was really upsetting. And for our players and staff to not feel safe in an NCAA tournament environment, it’s messed up.”

Roberts added that the NCAA and Gonzaga, the host school, worked to move the team to a different hotel. Neither Roberts nor the women’s athletics department immediately responded to a request for comment.

Utah’s deputy athletics director, Charmelle Green, who is Black, told KSL News of Salt Lake City that the team, along with band members and cheerleaders, were walking to a local restaurant for dinner when someone in a white truck drove up to the group, revved its engine, and yelled the N-word before speeding away.

“We all just were in shock, and we looked at each other like, did we just hear that?” Green said. “We kept walking, just shaking our heads, like, ‘I can’t believe that.’”

The team continued with the evening. Then, as they were leaving the restaurant, two trucks came near them, the drivers revved their engines and yelled the N-word. 

“I got emotional and started to cry,” Green told KSL. “I was just numb the entire night.” 

The team was staying in Idaho, about 35 minutes from Spokane, Washington, where it was scheduled to play during the opening weekend of the tournament. Utah was one of three teams staying in Idaho instead of Washington because of a lack of hotel space in the Spokane area, where Gonzaga is located. Utah’s athletic director Mark Harlan lamented the arrangement, telling KSL, “We should not have been there.” 

Gonzaga University officials acknowledged the situation in a statement shared on social media .

“Gonzaga University has been made aware of the racially disparaging comments made to visiting student-athletes and travel party members in Coeur d’Alene, Idaho, in advance of the NCAA Women’s First and Second Round Basketball Tournament games these past several days,” the statement began. 

“Hate speech in any form is repugnant, shameful and must never be tolerated. We worked hard to secure the opportunity to serve as the host institution, and our first priority is and must be the safety and welfare of all student-athletes, coaches, families and supporting staff. To this end, we have worked closely with the NCAA and program participants to support the security and safety of everyone involved. We are frustrated and deeply saddened to know that what should always be an amazing visitor and championship experience was in any way compromised by this situation, for it in no way reflects the values, standards, and beliefs to which we at Gonzaga University hold ourselves accountable.”

Judith Butler Thinks You’re Overreacting

How did gender become a scary word? The theorist who got us talking about the subject has answers.

By Jessica Bennett

Jessica Bennett is a contributing editor in Opinion, where she writes about gender, politics and personalities.

• Published March 24, 2024 Updated March 26, 2024

The first thing I did when reading Judith Butler’s new book, “Who’s Afraid of Gender?”, was to look up the word “phantasm,” which appears 41 times in the introduction alone. (It means illusion; the “phantasm of gender,” a threat rooted in fear and fantasy.)

The second thing I did was have a good chuckle about the title, because the answer to the question of who is afraid of gender was … well, I am? Even for someone who’s written on gender and feminism for more than a decade and who once carried the title of this newspaper’s “gender editor,” to talk about gender today can feel so fraught, so politicized, so caught in a war of words that debate, or even conversation, seems impossible.

I am perhaps the intended reader of Butler’s book, in which the notoriously esoteric philosopher turned pop celebrity dismantles how gender has been constructed as a threat throughout the modern world — to national security in Russia; to civilization, according to the Vatican ; to the American traditional family; to protecting children from pedophilia and grooming , according to some conservatives. In a single word, “gender” holds the power to seemingly drive people mad with fear.

Butler’s latest comes more than three decades after their first and most famous book, “Gender Trouble,” brought the idea of “gender as performance” into the mainstream. As it turns out, Butler — who has written 15 books since — never intended to return to the subject, even as a culture war raged. But then the political became personal: Butler was physically attacked in 2017 while speaking in Brazil, and burned in effigy by protesters who shouted, “ Take your ideology to hell .”

This conversation has been condensed and edited for clarity.

Did you ever think you’d see a world in which your ideas would be so widespread — and so fraught?

When I wrote “Gender Trouble,” I was a lecturer. I was teaching five classes, trying to work on this book I thought no one would read. Still, I knew I wasn’t just speaking for myself; there were other people who were strong feminists but also lesbian or gay or trying to figure out gender in ways that weren’t always welcome. But today, the people who are afraid of my ideas are the people who don’t read me. In other words, I don’t think it’s my ideas that they’re afraid of. They’ve come up with something else — a kind of fantasy of what I believe or who I am.

And of course it’s not just my views that are being caricatured, but gender more broadly — gender studies, policies that focus on gender, gender discrimination, gender and health care, anything with “gender” in it is a kind of terrifying prospect, at least for some.

So … who is afraid of gender?

It’s funny, I have a friend, a queer theorist. I told him the book’s name and he said, “Everyone! Everyone’s afraid of gender!”

What’s clear to me is that there is a set of strange fantasies about what gender is — how destructive it is, and how frightening it is — that a number of forces have been circulating: Viktor Orban, Vladimir Putin, Giorgia Meloni, Rishi Sunak, Jair Bolsonaro, Javier Milei, and of course Ron DeSantis, Donald Trump and lots of parents and communities in states like Oklahoma and Texas and Wyoming, who are seeking to pass legislation that bans the teaching of gender or reference to gender in books.

Obviously, those folks are very frightened of gender. They imbue it with power that I actually don’t think it has. But so are feminists who call themselves “gender critical,” or who are trans-exclusionary, or who have taken explicit positions against trans politics.

Can you describe what prompted you to return to this subject?

I was going to Brazil for a conference on the future of democracy. And I was told in advance that there were petitions against me speaking, and that they decided to focus on me because I’m the “papisa,” the female pope, of gender. I’m not quite sure how I got to have that distinction, but apparently I did. I got to the venue early, and I could hear the crowds outside. They’d built a kind of monstrous picture of me with horns, which I took to be overtly antisemitic — with red eyes and kind of a demonic look — with a bikini on. Like, why the bikini?

But in any case, I was burned in effigy. And that freaked me out. And then, when my partner and I were leaving, at the airport, we were attacked: Some woman came at me with a big trolley and she was screaming about pedophilia. I could not understand why.

You thank the young man who threw his body between you and the attacker, taking blows. Was this the first time you’d heard that “ pedophilia ” association?

I had given a talk on Jewish philosophy, and somebody in the back said, “Hands off our children!” I thought, What? I figured out later that the way that the anti-gender ideology movement works is to say: If you break down the taboo against homosexuality, if you allow gay and lesbian marriage, if you allow sex reassignment, then you’ve departed from all the laws of nature that keep the laws of morality intact — which means it’s a Pandora’s box; the whole panoply of perversions will emerge.

As I was preparing to interview you, I received a news alert about the “Don’t Say Gay” settlement in Florida, which says that schools cannot teach about L.G.B.T.Q. topics from kindergarten through the 8th grade, but clarifies that discussing them is allowed . You write that words have become “tacitly figured as recruiters and molesters,” which is behind the effort to remove this type of language from the classroom.

Teaching gender, or critical race theory, or even ethnic studies, is regularly characterized as forms of “indoctrination.” So for instance, that woman who was accusing me of supporting pedophilia, suggests that my work or my teaching would be an effort at “seduction” or “grooming.”

In my experience of teaching, people are arguing with each other all the time. There’s so much conflict. It’s chaotic. There are many things going on — but indoctrination is not one of them.

What about the warping of language on the left?

My version of feminist, queer, trans-affirmative politics is not about policing. I don’t think we should become the police. I’m afraid of the police. But I think a lot of people feel that the world is out of control, and one place where they can exercise some control is language. And it seems like moral discourse comes in then: Call me this. Use this term. We agree to use this language. What I like most about what young people are doing — and it’s not just the young, but everybody’s young now, according to me — is the experimentation. I love the experimentation. Like, let’s come up with new language. Let’s play. Let’s see what language makes us feel better about our lives. But I think we need to have a little more compassion for the adjustment process.

I want to talk for a moment about categories. You have occupied many — butch, queer, woman, nonbinary — yet you’ve also said you’re suspicious of them.

At the time that I wrote “Gender Trouble,” I called for a world in which we might think about genders being proliferated beyond the usual binary of man and woman. What would that look like? What would it be? So when people started talking about being “nonbinary,” I thought, well, I am that. I was trying to occupy that space of being between existing categories.

Do you still believe that gender is “performance?”

After “Gender Trouble” was published, there were some from the trans community who had problems with it. And I saw that my approach, what came to be called a “queer approach”— which was somewhat ironic toward categories — for some people, that’s not OK. They need their categories, they need them to be right, and for them gender is not constructed or performed.

Not everybody wants mobility. And I think I’ve taken that into account now.

But at the same time, for me, performativity is enacting who we are, both our social formation and what we’ve done with that social formation. I mean, my gestures: I didn’t make them up out of thin air — there’s a history of Jewish people who do this. I am inside of something, socially, culturally constructed. At the same time, I find my own way in it. And it’s always been my contention that we’re both formed and we form ourselves, and that’s a living paradox.

How do you define gender today?

Oh, goodness. I have, I suppose, revised my theory of gender — but that’s not the point of this book. I do make the point that “gender identity” is not all of what we mean by gender: It’s one thing that belongs to a cluster of things. Gender is also a framework — a very important framework — in law, in politics, for thinking about how inequality gets instituted in the world.

This is your first book with a nonacademic press. Was that a conscious decision?

Oh, yeah. I wanted to reach people.

It’s funny because many of your ideas do reach people, albeit in internet-era sound bites. I’m thinking about, for instance, of “gender is a drag” T-shirts or “ Judith Butler explained with cats .” It strikes me that a lot of people who claim to have read you have actually just read the Instagram caption of you.

Well, I don’t blame them for not reading that book. It was tough. And some of those sentences are truly unforgivable. Hopefully I didn’t do that in “Who’s Afraid of Gender?”

I feel like I’m more in touch with people who are mobilizing on the ground at the global level than I have been before. And that pleases me.

Trump promotes Lee Greenwood's 'God Bless The USA Bible': What to know about the book and its long journey

• Former president Donald Trump encourages supporters to buy Lee Greenwood's "God Bless The USA Bible," a project inspired by Nashville country musician's hit song.
• Resurgent version of Greenwood's Bible project a modified version from original concept, a change that likely followed 2021 shake-up in publishers.

After years with few updates about Lee Greenwood’s controversial Bible, the project is again resurgent with a recent promotion by former President Donald Trump.

“All Americans need to have a Bible in their home and I have many. It’s my favorite book,” Trump said in a video posted to social media Tuesday, encouraging supporters to purchase the “God Bless The USA Bible.” “Religion is so important and so missing, but it’s going to come back.”

Greenwood — the Nashville area country musician whose hit song “God Bless the USA” inspired the Bible with a similar namesake — has long been allies with Trump and other prominent Republicans, many of whom are featured in promotional material for the “God Bless The USA Bible.” But that reputational clout in conservative circles hasn’t necessarily translated to business success in the past, largely due to a major change in the book’s publishing plan.

Here's what to know about the Bible project’s journey so far and why it’s significant it’s back in the conservative limelight.

An unordinary Bible, a fiery debate

The “God Bless The USA Bible” received heightened attention since the outset due to its overt political features.

The text includes the U.S. Constitution, Bill of Rights, Declaration of Independence, Pledge of Allegiance, and the lyrics to the chorus to Greenwood’s “God Bless The USA.” Critics saw it as a symbol of Christian nationalism, a right-wing movement that believes the U.S. was founded as a Christian nation.

A petition emerged in 2021 calling Greenwood’s Bible “a toxic mix that will exacerbate the challenges to American evangelicalism.” From there, a broader conversation ensued about the standards by which publishers print Bibles.

Gatekeeping in Bible publishing

Greenwood’s early business partner on the project, a Hermitage-based marketing firm called Elite Source Pro, initially reached a manufacturing agreement with the Nashville-based HarperCollins Christian Publishing to print the “God Bless The USA Bible.”  

As part of that agreement, HarperCollins would publish the book but not sell or endorse it. But then HarperCollins reversed course , a major setback for Greenwood’s Bible.

The reversal by HarperCollins followed a decision by Zondervan — a publishing group under HarperCollins Christian Publishing and an official North American licensor for Bibles printed in the New International Version translation — to pass on the project. HarperCollins said the decision was unrelated to the petition or other public denunciations against Greenwood’s Bible.

The full backstory: Lee Greenwood's 'God Bless the USA Bible' finds new printer after HarperCollins Christian passes

A new translation and mystery publisher

The resurgent “God Bless The USA Bible” featured in Trump’s recent ad is an altered version of the original concept, a modification that likely followed the publishing shake-up.

Greenwood’s Bible is now printed in the King James Version, a different translation from the original pitch to HarperCollins.

Perhaps the biggest mystery is the new publisher. That manufacturer is producing a limited quantity of copies, leading to a delayed four-to-six weeks for a copy to ship.  

It’s also unclear which business partners are still involved in the project. Hugh Kirkman, who led Elite Service Pro, the firm that originally partnered with Greenwood for the project, responded to a request for comment by referring media inquiries to Greenwood’s publicist.

The publicist said Elite Source Pro is not a partner on the project and the Bible has always been printed in the King James Version.

"Several years ago, the Bible was going to be printed with the NIV translation, but something happened with the then licensor and the then potential publisher. As a result, this God Bless The USA Bible has always been printed with the King James Version translation," publicist Jeremy Westby said in a statement.

Westby did not have the name of the new licensee who is manufacturing the Bible.

Trump’s plug for the “God Bless The USA Bible” recycled language the former president is using to appeal to a conservative Christian base.

“Our founding fathers did a tremendous thing when they built America on Judeo-Christian values,” Trump said in his video on social media. “Now that foundation is under attack perhaps as never before.”

This is the Difference Between a Hypothesis and a Theory

What to Know A hypothesis is an assumption made before any research has been done. It is formed so that it can be tested to see if it might be true. A theory is a principle formed to explain the things already shown in data. Because of the rigors of experiment and control, it is much more likely that a theory will be true than a hypothesis.

As anyone who has worked in a laboratory or out in the field can tell you, science is about process: that of observing, making inferences about those observations, and then performing tests to see if the truth value of those inferences holds up. The scientific method is designed to be a rigorous procedure for acquiring knowledge about the world around us.

In scientific reasoning, a hypothesis is constructed before any applicable research has been done. A theory, on the other hand, is supported by evidence: it's a principle formed as an attempt to explain things that have already been substantiated by data.

Toward that end, science employs a particular vocabulary for describing how ideas are proposed, tested, and supported or disproven. And that's where we see the difference between a hypothesis and a theory .

A hypothesis is an assumption, something proposed for the sake of argument so that it can be tested to see if it might be true.

In the scientific method, the hypothesis is constructed before any applicable research has been done, apart from a basic background review. You ask a question, read up on what has been studied before, and then form a hypothesis.

What is a Hypothesis?

A hypothesis is usually tentative, an assumption or suggestion made strictly for the objective of being tested.

When a character which has been lost in a breed, reappears after a great number of generations, the most probable hypothesis is, not that the offspring suddenly takes after an ancestor some hundred generations distant, but that in each successive generation there has been a tendency to reproduce the character in question, which at last, under unknown favourable conditions, gains an ascendancy. Charles Darwin, On the Origin of Species , 1859 According to one widely reported hypothesis , cell-phone transmissions were disrupting the bees' navigational abilities. (Few experts took the cell-phone conjecture seriously; as one scientist said to me, "If that were the case, Dave Hackenberg's hives would have been dead a long time ago.") Elizabeth Kolbert, The New Yorker , 6 Aug. 2007

What is a Theory?

A theory , in contrast, is a principle that has been formed as an attempt to explain things that have already been substantiated by data. It is used in the names of a number of principles accepted in the scientific community, such as the Big Bang Theory . Because of the rigors of experimentation and control, its likelihood as truth is much higher than that of a hypothesis.

It is evident, on our theory , that coasts merely fringed by reefs cannot have subsided to any perceptible amount; and therefore they must, since the growth of their corals, either have remained stationary or have been upheaved. Now, it is remarkable how generally it can be shown, by the presence of upraised organic remains, that the fringed islands have been elevated: and so far, this is indirect evidence in favour of our theory . Charles Darwin, The Voyage of the Beagle , 1839 An example of a fundamental principle in physics, first proposed by Galileo in 1632 and extended by Einstein in 1905, is the following: All observers traveling at constant velocity relative to one another, should witness identical laws of nature. From this principle, Einstein derived his theory of special relativity. Alan Lightman, Harper's , December 2011

Non-Scientific Use

In non-scientific use, however, hypothesis and theory are often used interchangeably to mean simply an idea, speculation, or hunch (though theory is more common in this regard):

The theory of the teacher with all these immigrant kids was that if you spoke English loudly enough they would eventually understand. E. L. Doctorow, Loon Lake , 1979 Chicago is famous for asking questions for which there can be no boilerplate answers. Example: given the probability that the federal tax code, nondairy creamer, Dennis Rodman and the art of mime all came from outer space, name something else that has extraterrestrial origins and defend your hypothesis . John McCormick, Newsweek , 5 Apr. 1999 In his mind's eye, Miller saw his case suddenly taking form: Richard Bailey had Helen Brach killed because she was threatening to sue him over the horses she had purchased. It was, he realized, only a theory , but it was one he felt certain he could, in time, prove. Full of urgency, a man with a mission now that he had a hypothesis to guide him, he issued new orders to his troops: Find out everything you can about Richard Bailey and his crowd. Howard Blum, Vanity Fair , January 1995

And sometimes one term is used as a genus, or a means for defining the other:

Laplace's popular version of his astronomy, the Système du monde , was famous for introducing what came to be known as the nebular hypothesis , the theory that the solar system was formed by the condensation, through gradual cooling, of the gaseous atmosphere (the nebulae) surrounding the sun. Louis Menand, The Metaphysical Club , 2001 Researchers use this information to support the gateway drug theory — the hypothesis that using one intoxicating substance leads to future use of another. Jordy Byrd, The Pacific Northwest Inlander , 6 May 2015 Fox, the business and economics columnist for Time magazine, tells the story of the professors who enabled those abuses under the banner of the financial theory known as the efficient market hypothesis . Paul Krugman, The New York Times Book Review , 9 Aug. 2009

Incorrect Interpretations of "Theory"

Since this casual use does away with the distinctions upheld by the scientific community, hypothesis and theory are prone to being wrongly interpreted even when they are encountered in scientific contexts—or at least, contexts that allude to scientific study without making the critical distinction that scientists employ when weighing hypotheses and theories.

The most common occurrence is when theory is interpreted—and sometimes even gleefully seized upon—to mean something having less truth value than other scientific principles. (The word law applies to principles so firmly established that they are almost never questioned, such as the law of gravity.)

This mistake is one of projection: since we use theory in general use to mean something lightly speculated, then it's implied that scientists must be talking about the same level of uncertainty when they use theory to refer to their well-tested and reasoned principles.

The distinction has come to the forefront particularly on occasions when the content of science curricula in schools has been challenged—notably, when a school board in Georgia put stickers on textbooks stating that evolution was "a theory, not a fact, regarding the origin of living things." As Kenneth R. Miller, a cell biologist at Brown University, has said , a theory "doesn’t mean a hunch or a guess. A theory is a system of explanations that ties together a whole bunch of facts. It not only explains those facts, but predicts what you ought to find from other observations and experiments.”

While theories are never completely infallible, they form the basis of scientific reasoning because, as Miller said "to the best of our ability, we’ve tested them, and they’ve held up."
