How to think effectively: Six stages of critical thinking

6 stages in critical thinking

Credit: Elder / Paul

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

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

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

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

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

Unreflective thinker

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

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

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

Challenged thinker

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

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

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

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

Beginning thinker

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

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

Practicing thinker

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

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

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

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

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

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

Advanced thinker

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

Master thinker

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

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

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

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

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

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

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

How Should We Think: The 6 Stages Of Critical Thinking

Twitter

Photo:Graph: Paul Ratner. Credit: Elder / Paul

Most of us over the last year have had our strongest will tested and our endurance pushed to its limit. But it hasn't only been our emotions that have been getting pulled through ordeals, our minds have also been pulled like never-before, and sadly many of us have fallen for elaborate conspiracy theories without any evidence, and for other fake-news regarding the pandemic.

The key to searching for truth, even in the most extreme dilemma, is to engage in ' critical thinking '. This means that we can evaluate evidence and what people tell us objectively and reach a more accurate conclusion about a situation.

Two psychologists, Linda Elder and Richard Paul , have now devised a 6-stage-pyramid of critical thinking that lets individuals assess just how good a critical thinker they are, and therefore how they can improve their critical thinking going forward. It starts from the bottom rung ' the unreflective thinker ' and moves all the way up to ' master thinker '.

Stage One: The Unreflective Thinker

In this stage, people are pretty much automatons. They act on instinct and take what is told to them at face-value. The have high levels of prejudice and jumbled thinking or thinking that is based on very faulty logic.

It shouldn't be thought though that these people are all uneducated, as Elder and Paul state :

"It is perfectly possible for students to graduate from high school, or even college, and still be largely unreflective thinkers."

Stage Two: The Challenged Thinker

At this stage, people do actually think about issues and scenarios in some depth, they also know that logical flaws in thinking can result in very negative consequences for themselves and others. However, like the unreflective thinker, they are also affected by personal biases, though they may be able to recognise that they do possess these biases in the first-place.

In that stage, it is very hard for the individual, even if they understand that an argument is poor, to be able to specify where the flaw lies in the logic behind it. They know something isn't right, but they can't quite work out why.

Stage Three: The Beginning Thinker

People in that stage have begun to apply critical thinking across their daily lives. They can see that many people use faulty logic and can even point-out in some cases what these faults actually are. They are also more self-aware than the 'challenged thinker'. They can understand that they can be wrong about things and are able to question the truth behind information being fed to them from different sources.

These individuals have started to put reason before emotion and sometimes won't believe in something just because they want to believe it to be true. Critical thinking is still a challenge though for the 'beginner thinker'.

Stage Four: The Practicing Thinker

This is now the level where reasoning skills begin to play a significant role in the day-to-day lives of the individual. They can evaluate not only the validity of an argument but can also understand the 'soundness' of the logical system being put into practice.

These people are also often being self-challenged. Instead of hoping for something to be true, they attempt to use logic and rationality as their guide.

Stage Five: The Advanced Thinker

The psychologists believe that this stage is found mostly as a result of higher college or university education. These individuals fully submit themselves to the law of reason and actively fight their own prejudices, putting rational thought above other considerations.

They also have intellectual empathy, which means that they are able to begin to understand why other people think the way they do but at the same time can easily identify flaws in the structure of the arguments made by those with whom they disagree. Importantly, they are able to identify why arguments are wrong, which is often far more difficult than identifying why arguments are correct.

Stage Six: The Master Thinker

This individual is very rare. These people have put logic above all else and are able to deal with every argument and problem critically. They consistently push themselves to reach new levels of critical thinking and are able to do that even in cases where it is deeply uncomfortable.

They have passed aside their ego in the search for validity and truth. They search for weaknesses and biases even in their own thinking and may question the very nature and axioms of knowledge and logic itself.

The question is though, how do we elevate ourselves and others to the next level? It is most certainly a difficult task precisely because we have to identify and put aside our own prejudices, hopes and fundamental beliefs. The authors of the study emphasise that :

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

It is crucial then that we learn how to evaluate fundamental assumptions before reaching a conclusion if we want to have our will to be governed by logic rather than ignorance.

A Crash Course in Critical Thinking

What you need to know—and read—about one of the essential skills needed today..

Posted April 8, 2024 | Reviewed by Michelle Quirk

  • In research for "A More Beautiful Question," I did a deep dive into the current crisis in critical thinking.
  • Many people may think of themselves as critical thinkers, but they actually are not.
  • Here is a series of questions you can ask yourself to try to ensure that you are thinking critically.

Conspiracy theories. Inability to distinguish facts from falsehoods. Widespread confusion about who and what to believe.

These are some of the hallmarks of the current crisis in critical thinking—which just might be the issue of our times. Because if people aren’t willing or able to think critically as they choose potential leaders, they’re apt to choose bad ones. And if they can’t judge whether the information they’re receiving is sound, they may follow faulty advice while ignoring recommendations that are science-based and solid (and perhaps life-saving).

Moreover, as a society, if we can’t think critically about the many serious challenges we face, it becomes more difficult to agree on what those challenges are—much less solve them.

On a personal level, critical thinking can enable you to make better everyday decisions. It can help you make sense of an increasingly complex and confusing world.

In the new expanded edition of my book A More Beautiful Question ( AMBQ ), I took a deep dive into critical thinking. Here are a few key things I learned.

First off, before you can get better at critical thinking, you should understand what it is. It’s not just about being a skeptic. When thinking critically, we are thoughtfully reasoning, evaluating, and making decisions based on evidence and logic. And—perhaps most important—while doing this, a critical thinker always strives to be open-minded and fair-minded . That’s not easy: It demands that you constantly question your assumptions and biases and that you always remain open to considering opposing views.

In today’s polarized environment, many people think of themselves as critical thinkers simply because they ask skeptical questions—often directed at, say, certain government policies or ideas espoused by those on the “other side” of the political divide. The problem is, they may not be asking these questions with an open mind or a willingness to fairly consider opposing views.

When people do this, they’re engaging in “weak-sense critical thinking”—a term popularized by the late Richard Paul, a co-founder of The Foundation for Critical Thinking . “Weak-sense critical thinking” means applying the tools and practices of critical thinking—questioning, investigating, evaluating—but with the sole purpose of confirming one’s own bias or serving an agenda.

In AMBQ , I lay out a series of questions you can ask yourself to try to ensure that you’re thinking critically. Here are some of the questions to consider:

  • Why do I believe what I believe?
  • Are my views based on evidence?
  • Have I fairly and thoughtfully considered differing viewpoints?
  • Am I truly open to changing my mind?

Of course, becoming a better critical thinker is not as simple as just asking yourself a few questions. Critical thinking is a habit of mind that must be developed and strengthened over time. In effect, you must train yourself to think in a manner that is more effortful, aware, grounded, and balanced.

For those interested in giving themselves a crash course in critical thinking—something I did myself, as I was working on my book—I thought it might be helpful to share a list of some of the books that have shaped my own thinking on this subject. As a self-interested author, I naturally would suggest that you start with the new 10th-anniversary edition of A More Beautiful Question , but beyond that, here are the top eight critical-thinking books I’d recommend.

The Demon-Haunted World: Science as a Candle in the Dark , by Carl Sagan

This book simply must top the list, because the late scientist and author Carl Sagan continues to be such a bright shining light in the critical thinking universe. Chapter 12 includes the details on Sagan’s famous “baloney detection kit,” a collection of lessons and tips on how to deal with bogus arguments and logical fallacies.

6 stages in critical thinking

Clear Thinking: Turning Ordinary Moments Into Extraordinary Results , by Shane Parrish

The creator of the Farnham Street website and host of the “Knowledge Project” podcast explains how to contend with biases and unconscious reactions so you can make better everyday decisions. It contains insights from many of the brilliant thinkers Shane has studied.

Good Thinking: Why Flawed Logic Puts Us All at Risk and How Critical Thinking Can Save the World , by David Robert Grimes

A brilliant, comprehensive 2021 book on critical thinking that, to my mind, hasn’t received nearly enough attention . The scientist Grimes dissects bad thinking, shows why it persists, and offers the tools to defeat it.

Think Again: The Power of Knowing What You Don't Know , by Adam Grant

Intellectual humility—being willing to admit that you might be wrong—is what this book is primarily about. But Adam, the renowned Wharton psychology professor and bestselling author, takes the reader on a mind-opening journey with colorful stories and characters.

Think Like a Detective: A Kid's Guide to Critical Thinking , by David Pakman

The popular YouTuber and podcast host Pakman—normally known for talking politics —has written a terrific primer on critical thinking for children. The illustrated book presents critical thinking as a “superpower” that enables kids to unlock mysteries and dig for truth. (I also recommend Pakman’s second kids’ book called Think Like a Scientist .)

Rationality: What It Is, Why It Seems Scarce, Why It Matters , by Steven Pinker

The Harvard psychology professor Pinker tackles conspiracy theories head-on but also explores concepts involving risk/reward, probability and randomness, and correlation/causation. And if that strikes you as daunting, be assured that Pinker makes it lively and accessible.

How Minds Change: The Surprising Science of Belief, Opinion and Persuasion , by David McRaney

David is a science writer who hosts the popular podcast “You Are Not So Smart” (and his ideas are featured in A More Beautiful Question ). His well-written book looks at ways you can actually get through to people who see the world very differently than you (hint: bludgeoning them with facts definitely won’t work).

A Healthy Democracy's Best Hope: Building the Critical Thinking Habit , by M Neil Browne and Chelsea Kulhanek

Neil Browne, author of the seminal Asking the Right Questions: A Guide to Critical Thinking, has been a pioneer in presenting critical thinking as a question-based approach to making sense of the world around us. His newest book, co-authored with Chelsea Kulhanek, breaks down critical thinking into “11 explosive questions”—including the “priors question” (which challenges us to question assumptions), the “evidence question” (focusing on how to evaluate and weigh evidence), and the “humility question” (which reminds us that a critical thinker must be humble enough to consider the possibility of being wrong).

6 Steps for Effective Critical Thinking

On a daily basis, we face problems and situations that should be evaluated and solved, and we are challenged to understand different perspectives to think about these situations. Most of us are building our cognitive thinking based on previous similar situations or experiences. However, this may not guarantee a better solution for a problem , as our decision may be affected by emotions, non-prioritized facts, or other external influences that reflect on the final decision. Therefore, critical thinking tends to build a rational, open-mined process that depends on information and empirical evidence.

The National Council for Excellence in Critical Thinking defines critical thinking as an “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.” The process tends to help us judge and evaluate situations based on understanding the related data, analyze it, build a clear understanding of the problem, choose the proper solution, and take actions based on the established solution.

The critical thinking process prevents our minds from jumping directly to conclusions. Instead, it guides the mind through logical steps that tend to widen the range of perspectives, accept findings, put aside personal biases, and consider reasonable possibilities. This can be achieved through six steps: knowledge, comprehension, application, analyze, synthesis, and take action. Below is a brief description of each step and how to implement them.

critical thinking

Step 1: Knowledge

For every problem, clear vision puts us on the right path to solve it. This step identifies the argument or the problem that needs to be solved. Questions should be asked to acquire a deep understanding about the problem. In some cases, there is no actual problem, thus no need to move forward with other steps in the critical thinking model. The questions in this stage should be open-ended to allow the chance to discuss and explore main reasons. At this stage, two main questions need to be addressed: What is the problem? And why do we need to solve it?

Step 2: Comprehension

Once the problem is identified, the next step is to understand the situation and the facts aligned with it. The data is collected about the problem using any of the research methods that can be adopted depending on the problem, the type of the data available, and the deadline required to solve it.

Step 3: Application

This step continues the previous one to complete the understanding of different facts and resources required to solve the problem by building a linkage between the information and resources. Mind maps can be used to analyze the situation, build a relation between it and the core problem, and determine the best way to move forward.

Step 4: Analyze

Once the information is collected and linkages are built between it the main problems, the situation is analyzed in order to identify the situation, the strong points, the weak points, and the challenges faced while solving the problem. The priorities are set for the main causes and determine how they can be addressed in the solution. One of the commonly used tools that can be deployed to analyze the problem and the circumstances around it is the cause effect diagram , which divides the problem from its causes and aims to identify the different causes and categorize them based on their type and impact on the problem.

Step 5: Synthesis

In this stage, once the problem is fully analyzed and all the related information is considered, a decision should be formed about how to solve the problem and the initial routes to follow to take this decision into action. If there are number of solutions, they should be evaluated and prioritized in order to find the most advantageous solution. One of the tools that contribute choosing the problem solution is the SWOT analysis that tends to identify the solution’s strength, weakness, opportunity, and threats.

Step 6: Take Action

The final step is to build an evaluation about the problem that can be put into action. The result of critical thinking should be transferred into action steps. If the decision involves a specific project or team, a plan of action could be implemented to ensure that the solution is adopted and executed as planned.

The critical thinking method can be adopted to replace emotions and perusal biases when trying to think about a situation or a problem. The time for adopting critical thinking varies based on the problem; it may take few minutes to number of days. The advantage of deploying critical thinking is that it contributes to widening our perspectives about situations and broadening our thinking possibilities. However, these steps should be translated into a plan of action that ensures that the decided resolution is well achieved and integrated between all the involved bodies.

What Is Critical Thinking? | Definition & Examples

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

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

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

Critical thinking skills help you to:

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

Table of contents

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

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

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

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

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

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

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

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

Academic examples

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

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

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.

6 stages in critical thinking

  • Indiana University, Bloomington
  • State University of New York at Oneonta

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

Good critical thinkers can draw reasonable conclusions from a set of information, and discriminate between useful and less useful details to solve problems or make decisions. These skills are especially helpful at school and in the workplace, where employers prioritize the ability to think critically. Find out why and see how you can demonstrate that you have this ability.

Examples of Critical Thinking

The circumstances that demand critical thinking vary from industry to industry. Some examples include:

  • A triage nurse analyzes the cases at hand and decides the order by which the patients should be treated.
  • A plumber evaluates the materials that would best suit a particular job.
  • An attorney reviews the evidence and devises a strategy to win a case or to decide whether to settle out of court.
  • A manager analyzes customer feedback forms and uses this information to develop a customer service training session for employees.

Why Do Employers Value Critical Thinking Skills?

Employers want job candidates who can evaluate a situation using logical thought and offer the best solution.

Someone with critical thinking skills can be trusted to make decisions independently, and will not need constant handholding.

Hiring a critical thinker means that micromanaging won't be required. Critical thinking abilities are among the most sought-after skills in almost every industry and workplace. You can demonstrate critical thinking by using related keywords in your resume and cover letter and during your interview.

How to Demonstrate Critical Thinking in a Job Search

If critical thinking is a key phrase in the job listings you are applying for, be sure to emphasize your critical thinking skills throughout your job search.

Add Keywords to Your Resume

You can use critical thinking keywords (analytical, problem solving, creativity, etc.) in your resume. When describing your work history, include top critical thinking skills that accurately describe you. You can also include them in your resume summary, if you have one.

For example, your summary might read, “Marketing Associate with five years of experience in project management. Skilled in conducting thorough market research and competitor analysis to assess market trends and client needs, and to develop appropriate acquisition tactics.”

Mention Skills in Your Cover Letter

Include these critical thinking skills in your cover letter. In the body of your letter, mention one or two of these skills, and give specific examples of times when you have demonstrated them at work. Think about times when you had to analyze or evaluate materials to solve a problem.

Show the Interviewer Your Skills

You can use these skill words in an interview. Discuss a time when you were faced with a particular problem or challenge at work and explain how you applied critical thinking to solve it.

Some interviewers will give you a hypothetical scenario or problem, and ask you to use critical thinking skills to solve it. In this case, explain your thought process thoroughly to the interviewer. He or she is typically more focused on how you arrive at your solution rather than the solution itself. The interviewer wants to see you analyze and evaluate (key parts of critical thinking) the given scenario or problem.

Of course, each job will require different skills and experiences, so make sure you read the job description carefully and focus on the skills listed by the employer.

Top Critical Thinking Skills

Keep these in-demand skills in mind as you refine your critical thinking practice —whether for work or school.

Part of critical thinking is the ability to carefully examine something, whether it is a problem, a set of data, or a text. People with analytical skills can examine information, understand what it means, and properly explain to others the implications of that information.

  • Asking Thoughtful Questions
  • Data Analysis
  • Interpretation
  • Questioning Evidence
  • Recognizing Patterns

Communication

Often, you will need to share your conclusions with your employers or with a group of classmates or colleagues. You need to be able to communicate with others to share your ideas effectively. You might also need to engage in critical thinking in a group. In this case, you will need to work with others and communicate effectively to figure out solutions to complex problems.

  • Active Listening
  • Collaboration
  • Explanation
  • Interpersonal
  • Presentation
  • Verbal Communication
  • Written Communication

Critical thinking often involves creativity and innovation. You might need to spot patterns in the information you are looking at or come up with a solution that no one else has thought of before. All of this involves a creative eye that can take a different approach from all other approaches.

  • Flexibility
  • Conceptualization
  • Imagination
  • Drawing Connections
  • Synthesizing

Open-Mindedness

To think critically, you need to be able to put aside any assumptions or judgments and merely analyze the information you receive. You need to be objective, evaluating ideas without bias.

  • Objectivity
  • Observation

Problem-Solving

Problem-solving is another critical thinking skill that involves analyzing a problem, generating and implementing a solution, and assessing the success of the plan. Employers don’t simply want employees who can think about information critically. They also need to be able to come up with practical solutions.

  • Attention to Detail
  • Clarification
  • Decision Making
  • Groundedness
  • Identifying Patterns

More Critical Thinking Skills

  • Inductive Reasoning
  • Deductive Reasoning
  • Noticing Outliers
  • Adaptability

41+ Critical Thinking Examples (Definition + Practices)

practical psychology logo

Critical thinking is an essential skill in our information-overloaded world, where figuring out what is fact and fiction has become increasingly challenging.

But why is critical thinking essential? Put, critical thinking empowers us to make better decisions, challenge and validate our beliefs and assumptions, and understand and interact with the world more effectively and meaningfully.

Critical thinking is like using your brain's "superpowers" to make smart choices. Whether it's picking the right insurance, deciding what to do in a job, or discussing topics in school, thinking deeply helps a lot. In the next parts, we'll share real-life examples of when this superpower comes in handy and give you some fun exercises to practice it.

Critical Thinking Process Outline

a woman thinking

Critical thinking means thinking clearly and fairly without letting personal feelings get in the way. It's like being a detective, trying to solve a mystery by using clues and thinking hard about them.

It isn't always easy to think critically, as it can take a pretty smart person to see some of the questions that aren't being answered in a certain situation. But, we can train our brains to think more like puzzle solvers, which can help develop our critical thinking skills.

Here's what it looks like step by step:

Spotting the Problem: It's like discovering a puzzle to solve. You see that there's something you need to figure out or decide.

Collecting Clues: Now, you need to gather information. Maybe you read about it, watch a video, talk to people, or do some research. It's like getting all the pieces to solve your puzzle.

Breaking It Down: This is where you look at all your clues and try to see how they fit together. You're asking questions like: Why did this happen? What could happen next?

Checking Your Clues: You want to make sure your information is good. This means seeing if what you found out is true and if you can trust where it came from.

Making a Guess: After looking at all your clues, you think about what they mean and come up with an answer. This answer is like your best guess based on what you know.

Explaining Your Thoughts: Now, you tell others how you solved the puzzle. You explain how you thought about it and how you answered. 

Checking Your Work: This is like looking back and seeing if you missed anything. Did you make any mistakes? Did you let any personal feelings get in the way? This step helps make sure your thinking is clear and fair.

And remember, you might sometimes need to go back and redo some steps if you discover something new. If you realize you missed an important clue, you might have to go back and collect more information.

Critical Thinking Methods

Just like doing push-ups or running helps our bodies get stronger, there are special exercises that help our brains think better. These brain workouts push us to think harder, look at things closely, and ask many questions.

It's not always about finding the "right" answer. Instead, it's about the journey of thinking and asking "why" or "how." Doing these exercises often helps us become better thinkers and makes us curious to know more about the world.

Now, let's look at some brain workouts to help us think better:

1. "What If" Scenarios

Imagine crazy things happening, like, "What if there was no internet for a month? What would we do?" These games help us think of new and different ideas.

Pick a hot topic. Argue one side of it and then try arguing the opposite. This makes us see different viewpoints and think deeply about a topic.

3. Analyze Visual Data

Check out charts or pictures with lots of numbers and info but no explanations. What story are they telling? This helps us get better at understanding information just by looking at it.

4. Mind Mapping

Write an idea in the center and then draw lines to related ideas. It's like making a map of your thoughts. This helps us see how everything is connected.

There's lots of mind-mapping software , but it's also nice to do this by hand.

5. Weekly Diary

Every week, write about what happened, the choices you made, and what you learned. Writing helps us think about our actions and how we can do better.

6. Evaluating Information Sources

Collect stories or articles about one topic from newspapers or blogs. Which ones are trustworthy? Which ones might be a little biased? This teaches us to be smart about where we get our info.

There are many resources to help you determine if information sources are factual or not.

7. Socratic Questioning

This way of thinking is called the Socrates Method, named after an old-time thinker from Greece. It's about asking lots of questions to understand a topic. You can do this by yourself or chat with a friend.

Start with a Big Question:

"What does 'success' mean?"

Dive Deeper with More Questions:

"Why do you think of success that way?" "Do TV shows, friends, or family make you think that?" "Does everyone think about success the same way?"

"Can someone be a winner even if they aren't rich or famous?" "Can someone feel like they didn't succeed, even if everyone else thinks they did?"

Look for Real-life Examples:

"Who is someone you think is successful? Why?" "Was there a time you felt like a winner? What happened?"

Think About Other People's Views:

"How might a person from another country think about success?" "Does the idea of success change as we grow up or as our life changes?"

Think About What It Means:

"How does your idea of success shape what you want in life?" "Are there problems with only wanting to be rich or famous?"

Look Back and Think:

"After talking about this, did your idea of success change? How?" "Did you learn something new about what success means?"

8. Six Thinking Hats 

Edward de Bono came up with a cool way to solve problems by thinking in six different ways, like wearing different colored hats. You can do this independently, but it might be more effective in a group so everyone can have a different hat color. Each color has its way of thinking:

White Hat (Facts): Just the facts! Ask, "What do we know? What do we need to find out?"

Red Hat (Feelings): Talk about feelings. Ask, "How do I feel about this?"

Black Hat (Careful Thinking): Be cautious. Ask, "What could go wrong?"

Yellow Hat (Positive Thinking): Look on the bright side. Ask, "What's good about this?"

Green Hat (Creative Thinking): Think of new ideas. Ask, "What's another way to look at this?"

Blue Hat (Planning): Organize the talk. Ask, "What should we do next?"

When using this method with a group:

  • Explain all the hats.
  • Decide which hat to wear first.
  • Make sure everyone switches hats at the same time.
  • Finish with the Blue Hat to plan the next steps.

9. SWOT Analysis

SWOT Analysis is like a game plan for businesses to know where they stand and where they should go. "SWOT" stands for Strengths, Weaknesses, Opportunities, and Threats.

There are a lot of SWOT templates out there for how to do this visually, but you can also think it through. It doesn't just apply to businesses but can be a good way to decide if a project you're working on is working.

Strengths: What's working well? Ask, "What are we good at?"

Weaknesses: Where can we do better? Ask, "Where can we improve?"

Opportunities: What good things might come our way? Ask, "What chances can we grab?"

Threats: What challenges might we face? Ask, "What might make things tough for us?"

Steps to do a SWOT Analysis:

  • Goal: Decide what you want to find out.
  • Research: Learn about your business and the world around it.
  • Brainstorm: Get a group and think together. Talk about strengths, weaknesses, opportunities, and threats.
  • Pick the Most Important Points: Some things might be more urgent or important than others.
  • Make a Plan: Decide what to do based on your SWOT list.
  • Check Again Later: Things change, so look at your SWOT again after a while to update it.

Now that you have a few tools for thinking critically, let’s get into some specific examples.

Everyday Examples

Life is a series of decisions. From the moment we wake up, we're faced with choices – some trivial, like choosing a breakfast cereal, and some more significant, like buying a home or confronting an ethical dilemma at work. While it might seem that these decisions are disparate, they all benefit from the application of critical thinking.

10. Deciding to buy something

Imagine you want a new phone. Don't just buy it because the ad looks cool. Think about what you need in a phone. Look up different phones and see what people say about them. Choose the one that's the best deal for what you want.

11. Deciding what is true

There's a lot of news everywhere. Don't believe everything right away. Think about why someone might be telling you this. Check if what you're reading or watching is true. Make up your mind after you've looked into it.

12. Deciding when you’re wrong

Sometimes, friends can have disagreements. Don't just get mad right away. Try to see where they're coming from. Talk about what's going on. Find a way to fix the problem that's fair for everyone.

13. Deciding what to eat

There's always a new diet or exercise that's popular. Don't just follow it because it's trendy. Find out if it's good for you. Ask someone who knows, like a doctor. Make choices that make you feel good and stay healthy.

14. Deciding what to do today

Everyone is busy with school, chores, and hobbies. Make a list of things you need to do. Decide which ones are most important. Plan your day so you can get things done and still have fun.

15. Making Tough Choices

Sometimes, it's hard to know what's right. Think about how each choice will affect you and others. Talk to people you trust about it. Choose what feels right in your heart and is fair to others.

16. Planning for the Future

Big decisions, like where to go to school, can be tricky. Think about what you want in the future. Look at the good and bad of each choice. Talk to people who know about it. Pick what feels best for your dreams and goals.

School Examples

27. researching a topic.

For a history project, a student looks up different sources to understand an event from multiple viewpoints.

28. Debating an Issue

In a class discussion, students pick sides on a topic, like school uniforms, and share reasons to support their views.

29. Evaluating Sources

While writing an essay, a student checks if the information from a website is trustworthy or might be biased.

30. Problem Solving in Math

When stuck on a tricky math problem, a student tries different methods to find the answer instead of giving up.

31. Analyzing Literature

In English class, students discuss why a character in a book made certain choices and what those decisions reveal about them.

32. Testing a Hypothesis

For a science experiment, students guess what will happen and then conduct tests to see if they're right or wrong.

33. Giving Peer Feedback

After reading a classmate's essay, a student offers suggestions for improving it.

34. Questioning Assumptions

In a geography lesson, students consider why certain countries are called "developed" and what that label means.

35. Designing a Study

36. Interpreting Data

In a science class, students look at charts and graphs from a study, then discuss what the information tells them and if there are any patterns.

Critical Thinking Puzzles

critical thinking tree

Not all scenarios will have a single correct answer that can be figured out by thinking critically. Sometimes we have to think critically about ethical choices or moral behaviors. 

Here are some mind games and scenarios you can solve using critical thinking. You can see the solution(s) at the end of the post.

37. The Farmer, Fox, Chicken, and Grain Problem

A farmer is at a riverbank with a fox, a chicken, and a grain bag. He needs to get all three items across the river. However, his boat can only carry himself and one of the three items at a time. 

Here's the challenge:

  • If the fox is left alone with the chicken, the fox will eat the chicken.
  • If the chicken is left alone with the grain, the chicken will eat the grain.

How can the farmer get all three items across the river without any item being eaten? 

38. The Rope, Jar, and Pebbles Problem

You are in a room with two long ropes hanging from the ceiling. Each rope is just out of arm's reach from the other, so you can't hold onto one rope and reach the other simultaneously. 

Your task is to tie the two rope ends together, but you can't move the position where they hang from the ceiling.

You are given a jar full of pebbles. How do you complete the task?

39. The Two Guards Problem

Imagine there are two doors. One door leads to certain doom, and the other leads to freedom. You don't know which is which.

In front of each door stands a guard. One guard always tells the truth. The other guard always lies. You don't know which guard is which.

You can ask only one question to one of the guards. What question should you ask to find the door that leads to freedom?

40. The Hourglass Problem

You have two hourglasses. One measures 7 minutes when turned over, and the other measures 4 minutes. Using just these hourglasses, how can you time exactly 9 minutes?

41. The Lifeboat Dilemma

Imagine you're on a ship that's sinking. You get on a lifeboat, but it's already too full and might flip over. 

Nearby in the water, five people are struggling: a scientist close to finding a cure for a sickness, an old couple who've been together for a long time, a mom with three kids waiting at home, and a tired teenager who helped save others but is now in danger. 

You can only save one person without making the boat flip. Who would you choose?

42. The Tech Dilemma

You work at a tech company and help make a computer program to help small businesses. You're almost ready to share it with everyone, but you find out there might be a small chance it has a problem that could show users' private info. 

If you decide to fix it, you must wait two more months before sharing it. But your bosses want you to share it now. What would you do?

43. The History Mystery

Dr. Amelia is a history expert. She's studying where a group of people traveled long ago. She reads old letters and documents to learn about it. But she finds some letters that tell a different story than what most people believe. 

If she says this new story is true, it could change what people learn in school and what they think about history. What should she do?

The Role of Bias in Critical Thinking

Have you ever decided you don’t like someone before you even know them? Or maybe someone shared an idea with you that you immediately loved without even knowing all the details. 

This experience is called bias, which occurs when you like or dislike something or someone without a good reason or knowing why. It can also take shape in certain reactions to situations, like a habit or instinct. 

Bias comes from our own experiences, what friends or family tell us, or even things we are born believing. Sometimes, bias can help us stay safe, but other times it stops us from seeing the truth.

Not all bias is bad. Bias can be a mechanism for assessing our potential safety in a new situation. If we are biased to think that anything long, thin, and curled up is a snake, we might assume the rope is something to be afraid of before we know it is just a rope.

While bias might serve us in some situations (like jumping out of the way of an actual snake before we have time to process that we need to be jumping out of the way), it often harms our ability to think critically.

How Bias Gets in the Way of Good Thinking

Selective Perception: We only notice things that match our ideas and ignore the rest. 

It's like only picking red candies from a mixed bowl because you think they taste the best, but they taste the same as every other candy in the bowl. It could also be when we see all the signs that our partner is cheating on us but choose to ignore them because we are happy the way we are (or at least, we think we are).

Agreeing with Yourself: This is called “ confirmation bias ” when we only listen to ideas that match our own and seek, interpret, and remember information in a way that confirms what we already think we know or believe. 

An example is when someone wants to know if it is safe to vaccinate their children but already believes that vaccines are not safe, so they only look for information supporting the idea that vaccines are bad.

Thinking We Know It All: Similar to confirmation bias, this is called “overconfidence bias.” Sometimes we think our ideas are the best and don't listen to others. This can stop us from learning.

Have you ever met someone who you consider a “know it”? Probably, they have a lot of overconfidence bias because while they may know many things accurately, they can’t know everything. Still, if they act like they do, they show overconfidence bias.

There's a weird kind of bias similar to this called the Dunning Kruger Effect, and that is when someone is bad at what they do, but they believe and act like they are the best .

Following the Crowd: This is formally called “groupthink”. It's hard to speak up with a different idea if everyone agrees. But this can lead to mistakes.

An example of this we’ve all likely seen is the cool clique in primary school. There is usually one person that is the head of the group, the “coolest kid in school”, and everyone listens to them and does what they want, even if they don’t think it’s a good idea.

How to Overcome Biases

Here are a few ways to learn to think better, free from our biases (or at least aware of them!).

Know Your Biases: Realize that everyone has biases. If we know about them, we can think better.

Listen to Different People: Talking to different kinds of people can give us new ideas.

Ask Why: Always ask yourself why you believe something. Is it true, or is it just a bias?

Understand Others: Try to think about how others feel. It helps you see things in new ways.

Keep Learning: Always be curious and open to new information.

In today's world, everything changes fast, and there's so much information everywhere. This makes critical thinking super important. It helps us distinguish between what's real and what's made up. It also helps us make good choices. But thinking this way can be tough sometimes because of biases. These are like sneaky thoughts that can trick us. The good news is we can learn to see them and think better.

There are cool tools and ways we've talked about, like the "Socratic Questioning" method and the "Six Thinking Hats." These tools help us get better at thinking. These thinking skills can also help us in school, work, and everyday life.

We’ve also looked at specific scenarios where critical thinking would be helpful, such as deciding what diet to follow and checking facts.

Thinking isn't just a skill—it's a special talent we improve over time. Working on it lets us see things more clearly and understand the world better. So, keep practicing and asking questions! It'll make you a smarter thinker and help you see the world differently.

Critical Thinking Puzzles (Solutions)

The farmer, fox, chicken, and grain problem.

  • The farmer first takes the chicken across the river and leaves it on the other side.
  • He returns to the original side and takes the fox across the river.
  • After leaving the fox on the other side, he returns the chicken to the starting side.
  • He leaves the chicken on the starting side and takes the grain bag across the river.
  • He leaves the grain with the fox on the other side and returns to get the chicken.
  • The farmer takes the chicken across, and now all three items -- the fox, the chicken, and the grain -- are safely on the other side of the river.

The Rope, Jar, and Pebbles Problem

  • Take one rope and tie the jar of pebbles to its end.
  • Swing the rope with the jar in a pendulum motion.
  • While the rope is swinging, grab the other rope and wait.
  • As the swinging rope comes back within reach due to its pendulum motion, grab it.
  • With both ropes within reach, untie the jar and tie the rope ends together.

The Two Guards Problem

The question is, "What would the other guard say is the door to doom?" Then choose the opposite door.

The Hourglass Problem

  • Start both hourglasses. 
  • When the 4-minute hourglass runs out, turn it over.
  • When the 7-minute hourglass runs out, the 4-minute hourglass will have been running for 3 minutes. Turn the 7-minute hourglass over. 
  • When the 4-minute hourglass runs out for the second time (a total of 8 minutes have passed), the 7-minute hourglass will run for 1 minute. Turn the 7-minute hourglass again for 1 minute to empty the hourglass (a total of 9 minutes passed).

The Boat and Weights Problem

Take the cat over first and leave it on the other side. Then, return and take the fish across next. When you get there, take the cat back with you. Leave the cat on the starting side and take the cat food across. Lastly, return to get the cat and bring it to the other side.

The Lifeboat Dilemma

There isn’t one correct answer to this problem. Here are some elements to consider:

  • Moral Principles: What values guide your decision? Is it the potential greater good for humanity (the scientist)? What is the value of long-standing love and commitment (the elderly couple)? What is the future of young children who depend on their mothers? Or the selfless bravery of the teenager?
  • Future Implications: Consider the future consequences of each choice. Saving the scientist might benefit millions in the future, but what moral message does it send about the value of individual lives?
  • Emotional vs. Logical Thinking: While it's essential to engage empathy, it's also crucial not to let emotions cloud judgment entirely. For instance, while the teenager's bravery is commendable, does it make him more deserving of a spot on the boat than the others?
  • Acknowledging Uncertainty: The scientist claims to be close to a significant breakthrough, but there's no certainty. How does this uncertainty factor into your decision?
  • Personal Bias: Recognize and challenge any personal biases, such as biases towards age, profession, or familial status.

The Tech Dilemma

Again, there isn’t one correct answer to this problem. Here are some elements to consider:

  • Evaluate the Risk: How severe is the potential vulnerability? Can it be easily exploited, or would it require significant expertise? Even if the circumstances are rare, what would be the consequences if the vulnerability were exploited?
  • Stakeholder Considerations: Different stakeholders will have different priorities. Upper management might prioritize financial projections, the marketing team might be concerned about the product's reputation, and customers might prioritize the security of their data. How do you balance these competing interests?
  • Short-Term vs. Long-Term Implications: While launching on time could meet immediate financial goals, consider the potential long-term damage to the company's reputation if the vulnerability is exploited. Would the short-term gains be worth the potential long-term costs?
  • Ethical Implications : Beyond the financial and reputational aspects, there's an ethical dimension to consider. Is it right to release a product with a known vulnerability, even if the chances of it being exploited are low?
  • Seek External Input: Consulting with cybersecurity experts outside your company might be beneficial. They could provide a more objective risk assessment and potential mitigation strategies.
  • Communication: How will you communicate the decision, whatever it may be, both internally to your team and upper management and externally to your customers and potential users?

The History Mystery

Dr. Amelia should take the following steps:

  • Verify the Letters: Before making any claims, she should check if the letters are actual and not fake. She can do this by seeing when and where they were written and if they match with other things from that time.
  • Get a Second Opinion: It's always good to have someone else look at what you've found. Dr. Amelia could show the letters to other history experts and see their thoughts.
  • Research More: Maybe there are more documents or letters out there that support this new story. Dr. Amelia should keep looking to see if she can find more evidence.
  • Share the Findings: If Dr. Amelia believes the letters are true after all her checks, she should tell others. This can be through books, talks, or articles.
  • Stay Open to Feedback: Some people might agree with Dr. Amelia, and others might not. She should listen to everyone and be ready to learn more or change her mind if new information arises.

Ultimately, Dr. Amelia's job is to find out the truth about history and share it. It's okay if this new truth differs from what people used to believe. History is about learning from the past, no matter the story.

Critical thinking is essential to a health professional’s competence to assess, diagnose, and care for patients. Defined as the ability to apply higher-order cognitive skills (conceptualization, analysis, evaluation) and the disposition to be deliberate about thinking (being open-minded or intellectually honest) that lead to action that is logical and appropriate, critical thinking represents a “meta-competency” that transcends other knowledge, skills, abilities, and behaviors required in health care professions. Despite its importance, the developmental stages of critical thinking have not been delineated for nurses and physicians. As part of a task force of educators who considered different developmental stage theories, the authors have iteratively refined and proposed milestones in critical thinking. The attributes associated with unreflective, beginning, practicing, advanced, accomplished, and challenged critical thinkers are conceived as independent of an individual’s level of training. Depending on circumstances and environmental factors, even the most experienced clinician may demonstrate attributes associated with a challenged thinker. The authors use the illustrative case of a patient with abdominal pain to demonstrate how critical thinking may manifest in learners at different stages of development, analyzing how the learner at each stage applies information obtained in the patient interaction to arrive at a differential diagnosis and plan for evaluation. The authors share important considerations and provide this work as a foundation for the development of effective approaches to teaching and promoting critical thinking and to establishing expectations for learners in this essential meta-competency.

Six levels of critical thinkers

Six levels of critical thinkers

Researchers identified six predictable levels of critical thinkers:

  • The unreflective thinker
  • The challenged thinker
  • The beginner thinker
  • The practicing thinker
  • The advanced thinker
  • The master thinker

Using your mind more effectively is not automatic. Moving up on this pyramid of thinking is dependent on developing your critical thinking skills.

7.48K reads

The Unreflective Thinker

These are people who don't reflect on thinking nor consider the consequences of not thinking . Their prejudices and misconceptions lead them.

They do not consistently apply standards like accuracy, relevance, precision, and logic.

6.54K reads

The Challenged Thinker

People at this intellectual stage are aware of the importance of thinking and know that the lack of thinking can result in major issues.

  • They acknowledge that their own mental processes might have many flaws but are unable to identify all the weaknesses.
  • They may spot some instances of their own self-deception.
  • They may have a sense that proper thinking involves navigating assumptions, inferences, and points of view, but only on a basic level.

4.53K reads

The Beginning Thinker

Thinkers at this level can look to take control of their thinking across areas of their lives . They know their thinking can have blind spots, but initially take limited steps to address that.

  • They become self-aware in their thoughts.
  • They start looking at the concepts and biases underlying their ideas and develop higher internal standards of clarity, accuracy, and logic, all the while realizing their ego plays a major role in their decisions.
  • They can take some criticism of their mental approach.

4.02K reads

The Practicing Thinker

They not only recognize their own deficiencies but have the skills to address them.

  • They regularly analyze their mental processes.
  • They may still lack a systematic way of gaining insight into their thoughts and can fail to recognize self-deceptive reasoning.

To get to this stage, it is important to gain intellectual perseverance.

3.57K reads

The Advanced Thinker

The higher-level thinker has strong habits . They can analyze their thinking with insight. They can spot some of the prejudicial aspects of their thinking and of others . They possess:

  • "intellectual insight" to develop new thought habits
  • "intellectual integrity" to recognize areas of inconsistency and contradiction in their life
  • "intellectual empathy" to put oneself in the place of others in order to really understand them
  • "intellectual courage" to confront ideas and beliefs they don't necessarily believe in and have negative emotions toward

3.28K reads

The Master Thinker

This super-thinker is in control of how they process information and make decisions. They always seek to improve their thinking skills.

  • A master thinker commits to being fair
  • They have gained control over their egos
  • They display superior practical knowledge and insight.
  • They always re-examine their assumptions for weaknesses, logic, and biases.
  • They don't get upset with being intellectually confronted.

Critical Thinking in Everyday Life: 9 Strategies

The Unreflective Thinker (we are unaware of significant problems in our thinking)
The Challenged Thinker (we become aware of problems in our thinking)
The Beginning Thinker (we try to improve but without regular practice)
The Practicing Thinker (we recognize the necessity of regular practice)
The Advanced Thinker (we advance in accordance with our practice)
The Master Thinker (skilled & insightful thinking become second nature to us)

accept the fact that there are serious problems in our thinking (accepting the challenge to our thinking) and
begin regular practice.

In this article, we will explain 9 strategies that any motivated person can use to develop as a thinker. As we explain the strategy, we will describe it as if we were talking directly to such a person. Further details to our descriptions may need to be added for those who know little about critical thinking. Here are the 9:

Use “Wasted” Time.
A Problem A Day.
Internalize Intellectual Standards.
Keep An Intellectual Journal.
Reshape Your Character.
Deal with Your Ego.
Redefine the Way You See Things.
Get in touch with your emotions.
Analyze group influences on your life.

There is nothing magical about our ideas. No one of them is essential. Nevertheless, each represents a plausible way to begin to do something concrete to improve thinking in a regular way. Though you probably can’t do all of these at the same time, we recommend an approach in which you experiment with all of these over an extended period of time.

First Strategy: Use “Wasted” Time. All humans waste some time; that is, fail to use all of their time productively or even pleasurably. Sometimes we jump from one diversion to another, without enjoying any of them. Sometimes we become irritated about matters beyond our control. Sometimes we fail to plan well causing us negative consequences we could easily have avoided (for example, we spend time unnecessarily trapped in traffic — though we could have left a half hour earlier and avoided the rush). Sometimes we worry unproductively. Sometimes we spend time regretting what is past. Sometimes we just stare off blankly into space.

The key is that the time is “gone” even though, if we had thought about it and considered our options, we would never have deliberately spent our time in the way we did. So why not take advantage of the time you normally waste by practicing your critical thinking during that otherwise wasted time? For example, instead of sitting in front of the TV at the end of the day flicking from channel to channel in a vain search for a program worth watching, spend that time, or at least part of it, thinking back over your day and evaluating your strengths and weaknesses. For example, you might ask yourself questions like these:

When did I do my worst thinking today? When did I do my best? What in fact did I think about today? Did I figure anything out? Did I allow any negative thinking to frustrate me unnecessarily? If I had to repeat today what would I do differently? Why? Did I do anything today to further my long-term goals? Did I act in accordance with my own expressed values? If I spent every day this way for 10 years, would I at the end have accomplished something worthy of that time?

It would be important of course to take a little time with each question. It would also be useful to record your observations so that you are forced to spell out details and be explicit in what you recognize and see. As time passes, you will notice patterns in your thinking. Second Strategy: A Problem A Day. At the beginning of each day (perhaps driving to work or going to school) choose a problem to work on when you have free moments. Figure out the logic of the problem by identifying its elements. In other words, systematically think through the questions: What exactly is the problem? How can I put it into the form of a question. How does it relate to my goals, purposes, and needs?

Wherever possible take problems one by one. State the problem as clearly and precisely as you can.

Study the problem to make clear the “kind” of problem you are dealing with. Figure out, for example, what sorts of things you are going to have to do to solve it. Distinguish Problems over which you have some control from problems over which you have no control. Set aside the problems over which you have no control, concentrating your efforts on those problems you can potentially solve.

Figure out the information you need and actively seek that information.

Carefully analyze and interpret the information you collect, drawing what reasonable inferences you can.

Figure out your options for action. What can you do in the short term? In the long term? Distinguish problems under your control from problems beyond your control. Recognize explicitly your limitations as far as money, time, and power.

Evaluate your options, taking into account their advantages and disadvantages in the situation you are in.

Adopt a strategic approach to the problem and follow through on that strategy. This may involve direct action or a carefully thought-through wait-and-see strategy.

When you act, monitor the implications of your action as they begin to emerge. Be ready at a moment’s notice to revise your strategy if the situation requires it. Be prepared to shift your strategy or your analysis or statement of the problem, or all three, as more information about the problem becomes available to you.

Third Strategy: Internalize Intellectual Standards. Each week, develop a heightened awareness of one of the universal intellectual standards (clarity, precision, accuracy, relevance, depth, breadth, logicalness, significance). Focus one week on clarity, the next on accuracy, etc. For example, if you are focusing on clarity for the week, try to notice when you are being unclear in communicating with others. Notice when others are unclear in what they are saying.

When you are reading, notice whether you are clear about what you are reading. When you orally express or write out your views (for whatever reason), ask yourself whether you are clear about what you are trying to say. In doing this, of course, focus on four techniques of clarification : 1) Stating what you are saying explicitly and precisely (with careful consideration given to your choice of words), 2) Elaborating on your meaning in other words, 3) Giving examples of what you mean from experiences you have had, and 4) Using analogies , metaphors, pictures, or diagrams to illustrate what you mean. In other words, you will frequently STATE, ELABORATE, ILLUSTRATE, AND EXEMPLIFY your points. You will regularly ask others to do the same.

Fourth Strategy: Keep An Intellectual Journal. Each week, write out a certain number of journal entries. Use the following format (keeping each numbered stage separate):

Situation. Describe a situation that is, or was, emotionally significant to you (that is, that you deeply care about). Focus on one situation at a time.

Your Response. Describe what you did in response to that situation. Be specific and exact.

Analysis. Then analyze, in the light of what you have written, what precisely was going on in the situation. Dig beneath the surface.

Assessment. Assess the implications of your analysis. What did you learn about yourself? What would you do differently if you could re-live the situation?

Strategy Five: Reshape Your Character. Choose one intellectual trait---intellectual perseverance, autonomy, empathy, courage, humility, etc.--- to strive for each month, focusing on how you can develop that trait in yourself. For example, concentrating on intellectual humility, begin to notice when you admit you are wrong. Notice when you refuse to admit you are wrong, even in the face of glaring evidence that you are in fact wrong. Notice when you become defensive when another person tries to point out a deficiency in your work, or your thinking. Notice when your intellectual arrogance keeps you from learning, for example, when you say to yourself “I already know everything I need to know about this subject.” Or, “I know as much as he does. Who does he think he is forcing his opinions on me?” By owning your “ignorance,” you can begin to deal with it.

Strategy Six: Deal with Your Egocentrism. Egocentric thinking is found in the disposition in human nature to think with an automatic subconscious bias in favor of oneself. On a daily basis, you can begin to observe your egocentric thinking in action by contemplating questions like these: Under what circumstances do I think with a bias in favor of myself? Did I ever become irritable over small things? Did I do or say anything “irrational” to get my way? Did I try to impose my will upon others? Did I ever fail to speak my mind when I felt strongly about something, and then later feel resentment? Once you identify egocentric thinking in operation, you can then work to replace it with more rational thought through systematic self-reflection, thinking along the lines of: What would a rational person feel in this or that situation? What would a rational person do? How does that compare with what I want to do? (Hint: If you find that you continually conclude that a rational person would behave just as you behaved you are probably engaging in self-deception.)

Strategy Seven: Redefine the Way You See Things . We live in a world, both personal and social, in which every situation is “defined,” that is, given a meaning. How a situation is defined determines not only how we feel about it, but also how we act in it, and what implications it has for us. However, virtually every situation can be defined in more than one way. This fact carries with it tremendous opportunities. In principle, it lies within your power and mine to make our lives more happy and fulfilling than they are. Many of the negative definitions that we give to situations in our lives could in principle be transformed into positive ones. We can be happy when otherwise we would have been sad.

We can be fulfilled when otherwise we would have been frustrated. In this strategy, we practice redefining the way we see things, turning negatives into positives, dead-ends into new beginnings, mistakes into opportunities to learn. To make this strategy practical, we should create some specific guidelines for ourselves. For example, we might make ourselves a list of five to ten recurrent negative contexts in which we feel frustrated, angry, unhappy, or worried. We could then identify the definition in each case that is at the root of the negative emotion. We would then choose a plausible alternative definition for each and then plan for our new responses as well as new emotions. For example, if you tend to worry about all problems, both the ones you can do something about and those that you can’t; you can review the thinking in this nursery rhyme: “For every problem under the sun, there is a solution or there is none. If there be one, think til you find it. If there be none, then never mind it.”

Let’s look at another example. You do not have to define your initial approach to a member of the opposite sex in terms of the definition “his/her response will determine whether or not I am an attractive person.” Alternatively, you could define it in terms of the definition “let me test to see if this person is initially drawn to me—given the way they perceive me.” With the first definition in mind, you feel personally put down if the person is not “interested” in you; with the second definition you explicitly recognize that people respond not to the way a stranger is, but the way they look to them subjectively. You therefore do not take a failure to show interest in you (on the part of another) as a “defect” in you.

Strategy Eight: Get in touch with your emotions: Whenever you feel some negative emotion, systematically ask yourself: What, exactly, is the thinking leading to this emotion? For example, if you are angry, ask yourself, what is the thinking that is making me angry? What other ways could I think about this situation? For example, can you think about the situation so as to see the humor in it and what is pitiable in it? If you can, concentrate on that thinking and your emotions will (eventually) shift to match it.

Strategy Nine: Analyze group influences on your life: Closely analyze the behavior that is encouraged, and discouraged, in the groups to which you belong. For any given group, what are you "required" to believe? What are you "forbidden" to do? Every group enforces some level of conformity. Most people live much too much within the view of themselves projected by others. Discover what pressure you are bowing to and think explicitly about whether or not to reject that pressure.

Conclusion: The key point to keep in mind when devising strategies is that you are engaged in a personal experiment. You are testing ideas in your everyday life. You are integrating them, and building on them, in the light of your actual experience. For example, suppose you find the strategy “Redefine the Way You See Things” to be intuitive to you. So you use it to begin. Pretty soon you find yourself noticing the social definitions that rule many situations in your life. You recognize how your behavior is shaped and controlled by the definitions in use:

  • “I’m giving a party,” (Everyone therefore knows to act in a “partying” way)
  • “The funeral is Tuesday,” (There are specific social behaviors expected at a funeral)
  • “Jack is an acquaintance, not really a friend.” (We behave very differently in the two cases)

You begin to see how important and pervasive social definitions are. You begin to redefine situations in ways that run contrary to some commonly accepted definitions. You notice then how redefining situations (and relationships) enables you to “Get in Touch With Your Emotions.” You recognize that the way you think (that is, define things) generates the emotions you experience. When you think you are threatened (i.e., define a situation as “threatening”), you feel fear. If you define a situation as a “failure,” you may feel depressed. On the other hand, if you define that same situation as a “lesson or opportunity to learn” you feel empowered to learn. When you recognize this control that you are capable of exercising, the two strategies begin to work together and reinforce each other.

Next consider how you could integrate strategy #9 (“Analyze group influences on your life”) into your practice. One of the main things that groups do is control us by controlling the definitions we are allowed to operate with. When a group defines some things as “cool” and some as “dumb, ” the members of the group try to appear “cool” and not appear “dumb.” When the boss of a business says, “That makes a lot of sense,” his subordinates know they are not to say, “No, it is ridiculous.” And they know this because defining someone as the “boss” gives him/her special privileges to define situations and relationships.

You now have three interwoven strategies: you “Redefine the Way You See Things,” “Get in touch with your emotions,” and “Analyze group influences on your life.” The three strategies are integrated into one. You can now experiment with any of the other strategies, looking for opportunities to integrate them into your thinking and your life. If you follow through on some plan analogous to what we have described, you are developing as a thinker. More precisely, you are becoming a “Practicing” Thinker. Your practice will bring advancement. And with advancement, skilled and insightful thinking may becomes more and more natural to you.

10 elements of critical thinking – and how to develop them.

  • Share to Facebook
  • Share to Twitter
  • Share to Linkedin

creative idea.Concept of idea and innovation

My 6/7/24 post here – “Your Three Most Important Career Skills” – focused on the importance – and paucity – of critical thinking, critical listening, and critical reading.

Predictably, it prompted much reader response, mostly asking for elaboration.

What Comprises Critical Thinking

1. open-mindedness.

Malcolm Forbes postulated, “The role of education is to replace an empty mind with an open one.” Critical thinking needs receptivity to new ideas and perspectives, and willingness to reconsider one’s beliefs or opinions – no matter how fundamental – when new evidence or arguments arise.

2. Curiosity

“I’m not necessarily smarter than anyone else,” explained Albert Einstein. “I’m infinitely more curious.” He had a natural inclination – from early childhood – to ask questions, seek information, and explore various viewpoints. His favorite question: “What if…?”

Critical thinking is difficult, rigorous, almost always takes time and patience, and can be exhausting. That’s OK, but you should never let a conclusion be the place where you got tired of thinking. Push on.

4. Analysis

Analysis breaks down complex information into smaller parts, to understand its components and how they relate. It’s our left brain at work: linear, logical, methodical, sequential, rational, and objective. It engages in deductive thinking. Computers also do this.

5. Interpretation and Inference

Interpretation makes meaning out of data, relying not just on the brain, but also on experience. It’s our transcendental right brain having fun: creative, intuitive, random, holistic, and playful. It engages in inductive thinking, which today’s computers can’t do, but which A.I. is trying. Through inference, we make sensible deductions based on available information; reach reasonable, workable conclusions; and assess the viability of those conclusions.

6. Evaluation

What’s it worth? To make better decisions, we must accurately assess the credibility, relevance, and significance of information, arguments, and/or evidence.

7. Articulation

“If you can’t explain something to a six-year-old,” declared Albert Einstein, “you probably don’t understand it yourself.” Critical intake and critical output are one and the same.

8. Problem-solving

Both sides of our brains solve problems, just differently. Critical thinking is about the ability to do both with equal aplomb.

9. Self-Accountability and Reflection

Bertrand Russell advised, "In all affairs it's a healthy thing now and then to hang a question mark on the things you’ve long taken for granted." In this case – our own thinking processes, biases, and assumptions – “now and then” should mean “always and ever.”

10. Metacognition

Avid self-awareness of one's own thinking processes, cognitive strategies, and sphere of awareness can insure ongoing improvement of critical skills.

Developing Your Critical Thinking

1. think creatively.

“Curiosity is the key to creativity,” said Akio Morita, founder of Sony. Cultivate your creativity by exploring the unknown and the ambiguous. Welcome different perspectives, alternative solutions, and new thinking. Always be looking for the spark. Listen to the new guy.

2. Ask Questions

Nothing starts until there is a question – or better, multiple questions. Cultivate a curious mindset by asking probing questions. Question assumptions, biases, and implications. Nothing is off the table.

3. Seek Diverse Perspectives

Diversity is much more than demographics. “Diversity,” explained Malcolm Forbes, “is the art of thinking independently together.” Welcome a variety of viewpoints and opinions, especially those different from your own. Engage in active discussions with people who hold different beliefs. Constantly challenge what you know or believe.

4. Evaluate Information

Learn to critically – and objectively – evaluate the credibility, relevance, and reliability of sources of information. Today’s chaotic media circus, further manipulated by special interests, elevates this challenge.

5. Practice Analytical Thinking

As analytical thinking is more orderly than creative thinking, it can be practiced every day. Good idea.

6. Develop Logical Reasoning Skills

Practice deductive and inductive reasoning to draw logical conclusions from what you already have. But remember, logic and creativity are often at odds.

Things look different in the rear-view mirror, and a day (or more) later.

8. Learn Different Problem-Solving Techniques

Different problems can be solved different ways. Conversely, many problems can be solved many ways.

9. Learn Active Listening

Identify the barriers to active listening – presuppositions, for example – and eliminate them. Fast.

10. Read. Read. Read!

Reading is the most proactive and stimulating way of taking in the world, not by clicking on little blue links, but by real reading: wide, deep, and time-consuming reading, which has a positive effect on thinking. Great leaders are great readers. This we know.

None of this happens in a day, but starting it happens any day.
