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

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

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

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

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

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

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

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

Academic examples

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

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

Nonacademic examples

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

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

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

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

When encountering information, ask:

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

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

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

what is the concept of critical thinking

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.

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. Employers prioritize the ability to think critically—find out why, plus see how you can demonstrate that you have this ability throughout the job application process. 

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.

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 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.

Promote Your Skills in Your 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 critical thinking skills in mind as you update your resume and write your cover letter. As you've seen, you can also emphasize them at other points throughout the application process, such as your interview. 

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 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.

  • Clarification
  • Decision Making
  • Groundedness

Critical Thinking by Heather Butler , Diane Halpern LAST REVIEWED: 26 August 2022 LAST MODIFIED: 29 November 2011 DOI: 10.1093/obo/9780199828340-0019

Critical thinking has been described in many ways, but researchers generally agree that critical thinking involves rational, purposeful, and goal-directed thinking (see Defining Critical Thinking ). Diane F. Halpern defined critical thinking as an attempt to increase the probability of a desired outcome (e.g., making a sound decision, successfully solving a problem) by using certain cognitive skills and strategies. Critical thinking is more than just a collection of skills and strategies: it is a disposition toward engaging with problems. Critical thinkers are flexible, open-minded, persistent, and willing to exert mental energy working on tough problems. Unlike poor thinkers, critical thinkers are willing to admit they have made an error in judgment if confronted with contradictory evidence, and they operate on autopilot much less than poor thinkers (see Critical Thinking Dispositions ). There is good evidence that critical thinking skills and dispositions can be taught (see Teaching Critical Thinking ). This guide includes (a) sources that extol the importance of critical thinking, (b) research that identifies specific critical thinking skills and conceptualizations of critical thinking dispositions, (c) a list of the best practices for teaching critical thinking skills and dispositions, and (d) a review of research into ways of assessing critical thinking skills and dispositions (see Assessments ).

The sources highlighted here include textbooks, literature reviews, and meta-analyses related to critical thinking. These contributions come from both psychological ( Halpern 2003 ; Nisbett 1993 ; Sternberg, et al. 2007 ) and philosophical ( Ennis 1962 , Facione 1990 ) perspectives. Many of these general overviews are textbooks ( Facione 2011b ; Halpern 2003 ; Nisbett 1993 ; Sternberg, et al. 2007 ), while the other sources are review articles or commentaries. Most resources were intended for a general audience, but Sternberg, et al. 2007 was written specifically to address critical thinking in psychology. Those interested in a historical reference are referred to Ennis 1962 , which is credited by some as renewing contemporary interest in critical thinking. Those interested in a more recent conceptualization of critical thinking are referred to Facione 2011a , which is a short introduction to the field of critical thinking that would be appropriate for those new to the field, or Facione 1990 , which summarizes a collaborative definition of critical thinking among philosophers using the Delphi method. Facione 2011b would be a valuable resource for philosophers teaching critical thinking or logic courses to general audiences. For psychologists teaching critical thinking courses to a general audience, Halpern 2003 , an empirically based textbook, covers a wide range of topics; a new edition is expected soon. Fisher 2001 is also intended for general audiences and teaches a wide variety of critical thinking skills. Nisbett 1993 tackles the question of whether critical thinking skills can be taught and provides ample empirical evidence to that end. Sternberg, et al. 2007 is a good resource for psychology students interested in learning how to improve their scientific reasoning skills, a specific set of thinking skills needed by psychology and other science students.

This accessible paper defines critical thinking, elaborates on specific critical thinking skills, and discusses what it means to have (or not have) a critical thinking disposition. A distinction is made between system 1 (shallow processing) and system 2 (deeper processing) thinking. Good resource for students new to the field.

Halpern, Diane F. 2003. Thought & knowledge: An introduction to critical thinking . 4th ed. Mahwah, NJ: Lawrence Erlbaum.

This textbook, written by a cognitive psychologist, is grounded in theory and research from the learning sciences and offers practical examples. Chapters include an introduction to the topic and the correlates of critical thinking, memory, thought and language, reasoning, analyzing arguments, thinking as hypothesis testing, likelihood and uncertainty, decision making, development of problem-solving skills, and creative thinking.

Nisbett, Richard E. 1993. Rules for reasoning . Hillsdale, NJ: Lawrence Erlbaum.

This text is rich with empirical evidence that critical thinking skills can be taught to undergraduate and graduate students. Each chapter discusses research on an aspect of reasoning (e.g., statistical reasoning, heuristics, inductive reasoning) with special emphasis on teaching the application of these skills to everyday problems.

Sternberg, Robert J., Henry L. Roediger III, and Diane F. Halpern, eds. 2007. Critical thinking in psychology . New York: Cambridge Univ. Press.

This edited book explores several aspects of critical thinking that are needed to fully understand key topics in psychology such as experiment research, statistical inference, case studies, logical fallacies, and ethical judgments. Experts discuss the critical thinking strategies they engage in. Interesting discussion of historical breakthroughs due to critical thinking.

  • What is Critical Thinking?

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

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

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

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

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

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

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

Selection of a Critical Thinking Framework

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

Why the selection of a single critical thinking framework?

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

Critical Thinking

Critical Thinking

Jonathan Haber was an educational researcher, writer and entrepreneur working in the fields of critical-thinking education, assessment, and technology-enabled learning whose work has been featured in the New York Times , the Boston Globe , the Chronicle of Higher Education , and the Wall Street Journal . He is the author of another MIT Press Essential Knowledge book, MOOCs , and The Critical Voter .

How the concept of critical thinking emerged, how it has been defined, and how critical thinking skills can be taught.

Critical thinking is regularly cited as an essential twenty-first century skill, the key to success in school and work. Given our propensity to believe fake news, draw incorrect conclusions, and make decisions based on emotion rather than reason, it might even be said that critical thinking is vital to the survival of a democratic society. But what, exactly, is critical thinking? In this volume in the MIT Press Essential Knowledge series, Jonathan Haber explains how the concept of critical thinking emerged, how it has been defined, and how critical thinking skills can be taught and assessed.

Haber describes the term's origins in such disciplines as philosophy, psychology, and science. He examines the components of critical thinking, including structured thinking, language skills, background knowledge, and information literacy, along with such necessary intellectual traits as intellectual humility, empathy, and open-mindedness. He discusses how research has defined critical thinking, how elements of critical thinking have been taught for centuries, and how educators can teach critical thinking skills now.

Haber argues that the most important critical thinking issue today is that not enough people are doing enough of it. Fortunately, critical thinking can be taught, practiced, and evaluated. This book offers a guide for teachers, students, and aspiring critical thinkers everywhere, including advice for educational leaders and policy makers on how to make the teaching and learning of critical thinking an educational priority and practical reality.

Supplement to Critical Thinking

This supplement elaborates on the history of the articulation, promotion and adoption of critical thinking as an educational goal.

John Dewey (1910: 74, 82) introduced the term ‘critical thinking’ as the name of an educational goal, which he identified with a scientific attitude of mind. More commonly, he called the goal ‘reflective thought’, ‘reflective thinking’, ‘reflection’, or just ‘thought’ or ‘thinking’. He describes his book as written for two purposes. The first was to help people to appreciate the kinship of children’s native curiosity, fertile imagination and love of experimental inquiry to the scientific attitude. The second was to help people to consider how recognizing this kinship in educational practice “would make for individual happiness and the reduction of social waste” (iii). He notes that the ideas in the book obtained concreteness in the Laboratory School in Chicago.

Dewey’s ideas were put into practice by some of the schools that participated in the Eight-Year Study in the 1930s sponsored by the Progressive Education Association in the United States. For this study, 300 colleges agreed to consider for admission graduates of 30 selected secondary schools or school systems from around the country who experimented with the content and methods of teaching, even if the graduates had not completed the then-prescribed secondary school curriculum. One purpose of the study was to discover through exploration and experimentation how secondary schools in the United States could serve youth more effectively (Aikin 1942). Each experimental school was free to change the curriculum as it saw fit, but the schools agreed that teaching methods and the life of the school should conform to the idea (previously advocated by Dewey) that people develop through doing things that are meaningful to them, and that the main purpose of the secondary school was to lead young people to understand, appreciate and live the democratic way of life characteristic of the United States (Aikin 1942: 17–18). In particular, school officials believed that young people in a democracy should develop the habit of reflective thinking and skill in solving problems (Aikin 1942: 81). Students’ work in the classroom thus consisted more often of a problem to be solved than a lesson to be learned. Especially in mathematics and science, the schools made a point of giving students experience in clear, logical thinking as they solved problems. The report of one experimental school, the University School of Ohio State University, articulated this goal of improving students’ thinking:

Critical or reflective thinking originates with the sensing of a problem. It is a quality of thought operating in an effort to solve the problem and to reach a tentative conclusion which is supported by all available data. It is really a process of problem solving requiring the use of creative insight, intellectual honesty, and sound judgment. It is the basis of the method of scientific inquiry. The success of democracy depends to a large extent on the disposition and ability of citizens to think critically and reflectively about the problems which must of necessity confront them, and to improve the quality of their thinking is one of the major goals of education. (Commission on the Relation of School and College of the Progressive Education Association 1943: 745–746)

The Eight-Year Study had an evaluation staff, which developed, in consultation with the schools, tests to measure aspects of student progress that fell outside the focus of the traditional curriculum. The evaluation staff classified many of the schools’ stated objectives under the generic heading “clear thinking” or “critical thinking” (Smith, Tyler, & Evaluation Staff 1942: 35–36). To develop tests of achievement of this broad goal, they distinguished five overlapping aspects of it: ability to interpret data, abilities associated with an understanding of the nature of proof, and the abilities to apply principles of science, of social studies and of logical reasoning. The Eight-Year Study also had a college staff, directed by a committee of college administrators, whose task was to determine how well the experimental schools had prepared their graduates for college. The college staff compared the performance of 1,475 college students from the experimental schools with an equal number of graduates from conventional schools, matched in pairs by sex, age, race, scholastic aptitude scores, home and community background, interests, and probable future. They concluded that, on 18 measures of student success, the graduates of the experimental schools did a somewhat better job than the comparison group. The graduates from the six most traditional of the experimental schools showed no large or consistent differences. The graduates from the six most experimental schools, on the other hand, had much greater differences in their favour. The graduates of the two most experimental schools, the college staff reported:

… surpassed their comparison groups by wide margins in academic achievement, intellectual curiosity, scientific approach to problems, and interest in contemporary affairs. The differences in their favor were even greater in general resourcefulness, in enjoyment of reading, [in] participation in the arts, in winning non-academic honors, and in all aspects of college life except possibly participation in sports and social activities. (Aikin 1942: 114)

One of these schools was a private school with students from privileged families and the other the experimental section of a public school with students from non-privileged families. The college staff reported that the graduates of the two schools were indistinguishable from each other in terms of college success.

In 1933 Dewey issued an extensively rewritten edition of his How We Think (Dewey 1910), with the sub-title “A restatement of the relation of reflective thinking to the educative process”. Although the restatement retains the basic structure and content of the original book, Dewey made a number of changes. He rewrote and simplified his logical analysis of the process of reflection, made his ideas clearer and more definite, replaced the terms ‘induction’ and ‘deduction’ by the phrases ‘control of data and evidence’ and ‘control of reasoning and concepts’, added more illustrations, rearranged chapters, and revised the parts on teaching to reflect changes in schools since 1910. In particular, he objected to one-sided practices of some “experimental” and “progressive” schools that allowed children freedom but gave them no guidance, citing as objectionable practices novelty and variety for their own sake, experiences and activities with real materials but of no educational significance, treating random and disconnected activity as if it were an experiment, failure to summarize net accomplishment at the end of an inquiry, non-educative projects, and treatment of the teacher as a negligible factor rather than as “the intellectual leader of a social group” (Dewey 1933: 273). Without explaining his reasons, Dewey eliminated the previous edition’s uses of the words ‘critical’ and ‘uncritical’, thus settling firmly on ‘reflection’ or ‘reflective thinking’ as the preferred term for his subject-matter. In the revised edition, the word ‘critical’ occurs only once, where Dewey writes that “a person may not be sufficiently critical about the ideas that occur to him” (1933: 16, italics in original); being critical is thus a component of reflection, not the whole of it. In contrast, the Eight-Year Study by the Progressive Education Association treated ‘critical thinking’ and ‘reflective thinking’ as synonyms.

In the same period, Dewey collaborated on a history of the Laboratory School in Chicago with two former teachers from the school (Mayhew & Edwards 1936). The history describes the school’s curriculum and organization, activities aimed at developing skills, parents’ involvement, and the habits of mind that the children acquired. A concluding chapter evaluates the school’s achievements, counting as a success its staging of the curriculum to correspond to the natural development of the growing child. In two appendices, the authors describe the evolution of Dewey’s principles of education and Dewey himself describes the theory of the Chicago experiment (Dewey 1936).

Glaser (1941) reports in his doctoral dissertation the method and results of an experiment in the development of critical thinking conducted in the fall of 1938. He defines critical thinking as Dewey defined reflective thinking:

Critical thinking calls for a persistent effort to examine any belief or supposed form of knowledge in the light of the evidence that supports it and the further conclusions to which it tends. (Glaser 1941: 6; cf. Dewey 1910: 6; Dewey 1933: 9)

In the experiment, eight lesson units directed at improving critical thinking abilities were taught to four grade 12 high school classes, with pre-test and post-test of the students using the Otis Quick-Scoring Mental Ability Test and the Watson-Glaser Tests of Critical Thinking (developed in collaboration with Glaser’s dissertation sponsor, Goodwin Watson). The average gain in scores on these tests was greater to a statistically significant degree among the students who received the lessons in critical thinking than among the students in a control group of four grade 12 high school classes taking the usual curriculum in English. Glaser concludes:

The aspect of critical thinking which appears most susceptible to general improvement is the attitude of being disposed to consider in a thoughtful way the problems and subjects that come within the range of one’s experience. An attitude of wanting evidence for beliefs is more subject to general transfer. Development of skill in applying the methods of logical inquiry and reasoning, however, appears to be specifically related to, and in fact limited by, the acquisition of pertinent knowledge and facts concerning the problem or subject matter toward which the thinking is to be directed. (Glaser 1941: 175)

Retest scores and observable behaviour indicated that students in the intervention group retained their growth in ability to think critically for at least six months after the special instruction.

In 1948 a group of U.S. college examiners decided to develop taxonomies of educational objectives with a common vocabulary that they could use for communicating with each other about test items. The first of these taxonomies, for the cognitive domain, appeared in 1956 (Bloom et al. 1956), and included critical thinking objectives. It has become known as Bloom’s taxonomy. A second taxonomy, for the affective domain (Krathwohl, Bloom, & Masia 1964), and a third taxonomy, for the psychomotor domain (Simpson 1966–67), appeared later. Each of the taxonomies is hierarchical, with achievement of a higher educational objective alleged to require achievement of corresponding lower educational objectives.

Bloom’s taxonomy has six major categories. From lowest to highest, they are knowledge, comprehension, application, analysis, synthesis, and evaluation. Within each category, there are sub-categories, also arranged hierarchically from the educationally prior to the educationally posterior. The lowest category, though called ‘knowledge’, is confined to objectives of remembering information and being able to recall or recognize it, without much transformation beyond organizing it (Bloom et al. 1956: 28–29). The five higher categories are collectively termed “intellectual abilities and skills” (Bloom et al. 1956: 204). The term is simply another name for critical thinking abilities and skills:

Although information or knowledge is recognized as an important outcome of education, very few teachers would be satisfied to regard this as the primary or the sole outcome of instruction. What is needed is some evidence that the students can do something with their knowledge, that is, that they can apply the information to new situations and problems. It is also expected that students will acquire generalized techniques for dealing with new problems and new materials. Thus, it is expected that when the student encounters a new problem or situation, he will select an appropriate technique for attacking it and will bring to bear the necessary information, both facts and principles. This has been labeled “critical thinking” by some, “reflective thinking” by Dewey and others, and “problem solving” by still others. In the taxonomy, we have used the term “intellectual abilities and skills”. (Bloom et al. 1956: 38)

Comprehension and application objectives, as their names imply, involve understanding and applying information. Critical thinking abilities and skills show up in the three highest categories of analysis, synthesis and evaluation. The condensed version of Bloom’s taxonomy (Bloom et al. 1956: 201–207) gives the following examples of objectives at these levels:

  • analysis objectives : ability to recognize unstated assumptions, ability to check the consistency of hypotheses with given information and assumptions, ability to recognize the general techniques used in advertising, propaganda and other persuasive materials
  • synthesis objectives : organizing ideas and statements in writing, ability to propose ways of testing a hypothesis, ability to formulate and modify hypotheses
  • evaluation objectives : ability to indicate logical fallacies, comparison of major theories about particular cultures

The analysis, synthesis and evaluation objectives in Bloom’s taxonomy collectively came to be called the “higher-order thinking skills” (Tankersley 2005: chap. 5). Although the analysis-synthesis-evaluation sequence mimics phases in Dewey’s (1933) logical analysis of the reflective thinking process, it has not generally been adopted as a model of a critical thinking process. While commending the inspirational value of its ratio of five categories of thinking objectives to one category of recall objectives, Ennis (1981b) points out that the categories lack criteria applicable across topics and domains. For example, analysis in chemistry is so different from analysis in literature that there is not much point in teaching analysis as a general type of thinking. Further, the postulated hierarchy seems questionable at the higher levels of Bloom’s taxonomy. For example, ability to indicate logical fallacies hardly seems more complex than the ability to organize statements and ideas in writing.

A revised version of Bloom’s taxonomy (Anderson et al. 2001) distinguishes the intended cognitive process in an educational objective (such as being able to recall, to compare or to check) from the objective’s informational content (“knowledge”), which may be factual, conceptual, procedural, or metacognitive. The result is a so-called “Taxonomy Table” with four rows for the kinds of informational content and six columns for the six main types of cognitive process. The authors name the types of cognitive process by verbs, to indicate their status as mental activities. They change the name of the ‘comprehension’ category to ‘understand’ and of the ‘synthesis’ category to ’create’, and switch the order of synthesis and evaluation. The result is a list of six main types of cognitive process aimed at by teachers: remember, understand, apply, analyze, evaluate, and create. The authors retain the idea of a hierarchy of increasing complexity, but acknowledge some overlap, for example between understanding and applying. And they retain the idea that critical thinking and problem solving cut across the more complex cognitive processes. The terms ‘critical thinking’ and ‘problem solving’, they write:

are widely used and tend to become touchstones of curriculum emphasis. Both generally include a variety of activities that might be classified in disparate cells of the Taxonomy Table. That is, in any given instance, objectives that involve problem solving and critical thinking most likely call for cognitive processes in several categories on the process dimension. For example, to think critically about an issue probably involves some Conceptual knowledge to Analyze the issue. Then, one can Evaluate different perspectives in terms of the criteria and, perhaps, Create a novel, yet defensible perspective on this issue. (Anderson et al. 2001: 269–270; italics in original)

In the revised taxonomy, only a few sub-categories, such as inferring, have enough commonality to be treated as a distinct critical thinking ability that could be taught and assessed as a general ability.

A landmark contribution to philosophical scholarship on the concept of critical thinking was a 1962 article in the Harvard Educational Review by Robert H. Ennis, with the title “A concept of critical thinking: A proposed basis for research in the teaching and evaluation of critical thinking ability” (Ennis 1962). Ennis took as his starting-point a conception of critical thinking put forward by B. Othanel Smith:

We shall consider thinking in terms of the operations involved in the examination of statements which we, or others, may believe. A speaker declares, for example, that “Freedom means that the decisions in America’s productive effort are made not in the minds of a bureaucracy but in the free market”. Now if we set about to find out what this statement means and to determine whether to accept or reject it, we would be engaged in thinking which, for lack of a better term, we shall call critical thinking. If one wishes to say that this is only a form of problem-solving in which the purpose is to decide whether or not what is said is dependable, we shall not object. But for our purposes we choose to call it critical thinking. (Smith 1953: 130)

Adding a normative component to this conception, Ennis defined critical thinking as “the correct assessing of statements” (Ennis 1962: 83). On the basis of this definition, he distinguished 12 “aspects” of critical thinking corresponding to types or aspects of statements, such as judging whether an observation statement is reliable and grasping the meaning of a statement. He noted that he did not include judging value statements. Cutting across the 12 aspects, he distinguished three dimensions of critical thinking: logical (judging relationships between meanings of words and statements), criterial (knowledge of the criteria for judging statements), and pragmatic (the impression of the background purpose). For each aspect, Ennis described the applicable dimensions, including criteria. He proposed the resulting construct as a basis for developing specifications for critical thinking tests and for research on instructional methods and levels.

In the 1970s and 1980s there was an upsurge of attention to the development of thinking skills. The annual International Conference on Critical Thinking and Educational Reform has attracted since its start in 1980 tens of thousands of educators from all levels. In 1983 the College Entrance Examination Board proclaimed reasoning as one of six basic academic competencies needed by college students (College Board 1983). Departments of education in the United States and around the world began to include thinking objectives in their curriculum guidelines for school subjects. For example, Ontario’s social sciences and humanities curriculum guideline for secondary schools requires “the use of critical and creative thinking skills and/or processes” as a goal of instruction and assessment in each subject and course (Ontario Ministry of Education 2013: 30). The document describes critical thinking as follows:

Critical thinking is the process of thinking about ideas or situations in order to understand them fully, identify their implications, make a judgement, and/or guide decision making. Critical thinking includes skills such as questioning, predicting, analysing, synthesizing, examining opinions, identifying values and issues, detecting bias, and distinguishing between alternatives. Students who are taught these skills become critical thinkers who can move beyond superficial conclusions to a deeper understanding of the issues they are examining. They are able to engage in an inquiry process in which they explore complex and multifaceted issues, and questions for which there may be no clear-cut answers (Ontario Ministry of Education 2013: 46).

Sweden makes schools responsible for ensuring that each pupil who completes compulsory school “can make use of critical thinking and independently formulate standpoints based on knowledge and ethical considerations” (Skolverket 2018: 12). Subject syllabi incorporate this requirement, and items testing critical thinking skills appear on national tests that are a required step toward university admission. For example, the core content of biology, physics and chemistry in years 7-9 includes critical examination of sources of information and arguments encountered by pupils in different sources and social discussions related to these sciences, in both digital and other media. (Skolverket 2018: 170, 181, 192). Correspondingly, in year 9 the national tests require using knowledge of biology, physics or chemistry “to investigate information, communicate and come to a decision on issues concerning health, energy, technology, the environment, use of natural resources and ecological sustainability” (see the message from the School Board ). Other jurisdictions similarly embed critical thinking objectives in curriculum guidelines.

At the college level, a new wave of introductory logic textbooks, pioneered by Kahane (1971), applied the tools of logic to contemporary social and political issues. Popular contemporary textbooks of this sort include those by Bailin and Battersby (2016b), Boardman, Cavender and Kahane (2018), Browne and Keeley (2018), Groarke and Tindale (2012), and Moore and Parker (2020). In their wake, colleges and universities in North America transformed their introductory logic course into a general education service course with a title like ‘critical thinking’ or ‘reasoning’. In 1980, the trustees of California’s state university and colleges approved as a general education requirement a course in critical thinking, described as follows:

Instruction in critical thinking is to be designed to achieve an understanding of the relationship of language to logic, which should lead to the ability to analyze, criticize, and advocate ideas, to reason inductively and deductively, and to reach factual or judgmental conclusions based on sound inferences drawn from unambiguous statements of knowledge or belief. The minimal competence to be expected at the successful conclusion of instruction in critical thinking should be the ability to distinguish fact from judgment, belief from knowledge, and skills in elementary inductive and deductive processes, including an understanding of the formal and informal fallacies of language and thought. (Dumke 1980)

Since December 1983, the Association for Informal Logic and Critical Thinking has sponsored sessions at the three annual divisional meetings of the American Philosophical Association. In December 1987, the Committee on Pre-College Philosophy of the American Philosophical Association invited Peter Facione to make a systematic inquiry into the current state of critical thinking and critical thinking assessment. Facione assembled a group of 46 other academic philosophers and psychologists to participate in a multi-round Delphi process, whose product was entitled Critical Thinking: A Statement of Expert Consensus for Purposes of Educational Assessment and Instruction (Facione 1990a). The statement listed abilities and dispositions that should be the goals of a lower-level undergraduate course in critical thinking. Researchers in nine European countries determined which of these skills and dispositions employers expect of university graduates (Dominguez 2018 a), compared those expectations to critical thinking educational practices in post-secondary educational institutions (Dominguez 2018b), developed a course on critical thinking education for university teachers (Dominguez 2018c) and proposed in response to identified gaps between expectations and practices an “educational protocol” that post-secondary educational institutions in Europe could use to develop critical thinking (Elen et al. 2019).

Philosophy Behind Critical Thinking: A Concise Overview

Philosophy Behind Critical Thinking

The philosophy behind critical thinking delves into the deeper understanding of what it means to think critically and to develop the ability to reason, analyze, and evaluate information in a structured and systematic manner. Critical thinking has intricate connections with philosophy, mainly because it originated from ancient philosophical teachings. At its core, the concept of critical thinking is rooted in the Socratic method of questioning, which emphasizes the importance of inquiry and rational thinking as a means to achieve knowledge.

what is the concept of critical thinking

Understanding critical thinking necessitates exploring the various philosophical groundings, which delves into epistemology, the branch of philosophy that deals with knowledge, truth, and belief. Epistemological theories help elucidate different approaches to critical thinking, such as the psychological approach, focusing on cognitive processes, and the cultural and social context approach, emphasizing the importance of context in shaping critical thought. In the realm of education, the role of critical thinking cannot be understated, as it is a vital component of teaching and learning, shaping the way individuals process and interpret information and develop intellectually.

Key Takeaways

  • Critical thinking is deeply rooted in ancient philosophical teachings, particularly the Socratic method of questioning.
  • Different philosophical groundings provide varying approaches to critical thinking, such as psychological and cultural/social context approaches.
  • The importance of critical thinking in education is paramount, as it shapes how individuals process, interpret, and develop intellectually.

Understanding Critical Thinking

Definition and Process

Critical thinking is the ability to think clearly and rationally about what to do or what to believe. It involves engaging in reflective and independent thinking . To understand the logical connections between ideas, one needs to identify, construct, and evaluate arguments.

Logic, Reason, Rationality

Logic, reason, and rationality are essential components of critical thinking. Logic refers to the systematic approach to reasoning and validating claims through principles and rules. Reasoning, on the other hand, is the process of drawing conclusions based on logic, evidence, and assumptions. Rationality encompasses the use of logic and reason to make well-informed decisions, judgments, and evaluations.

Strategies and Patterns

To develop critical thinking skills, individuals must employ various strategies and recognize patterns in their thinking. Some common strategies include:

  • Analysis : Breaking down complex problems, data, or texts into simpler parts to understand what they mean and explain the implications to others.
  • Interpretation : Making sense of information and grasping its relevance in a given context.
  • Inference : Drawing reasonable conclusions based on available evidence and logic.
  • Evaluation : Assessing the credibility and validity of claims, arguments, or sources of information.

Recognizing patterns in thinking involves identifying common errors, biases, and other factors that might hinder critical thinking and refining one’s thought process accordingly.

Justification and Argumentation

Justification and argumentation play a crucial role in critical thinking. Justification refers to providing reasons or evidence in support of a claim, while argumentation involves constructing and evaluating arguments . Both justification and argumentation require logical reasoning, analysis of evidence, and clear communication of ideas.

Clarity and Reflection

Clarity is essential for effective critical thinking. This entails expressing ideas and arguments in a clear, concise, and organized manner. Furthermore, critical thinkers must also engage in reflection — the process of examining their own thought processes, assumptions, and biases. Reflecting on one’s beliefs and values helps individuals refine their thinking and develop a more nuanced understanding of the world around them.

In conclusion, understanding critical thinking involves exploring its definition, process, and key components, such as logic, reason, rationality, strategies, patterns, justification, argumentation, clarity, and reflection. By cultivating a strong foundation in these areas, individuals can develop their ability to think critically and make well-informed decisions in various aspects of life.

Psychological Approach to Critical Thinking

what is the concept of critical thinking

Cognition and Pattern Recognition

The psychological approach to critical thinking emphasizes the role of cognition and pattern recognition in the process. Cognitive psychologists recognize that our minds have a natural ability to identify patterns and relationships in the information we encounter. This involves categorizing, comparing, and evaluating various pieces of information. By developing cognitive skills, individuals can more effectively analyze and evaluate complex arguments, ultimately fostering their critical thinking abilities.

Bias and Judgments

Another aspect of the psychological approach to critical thinking is the examination of biases and judgments. Bias refers to the systematic errors or distortions in human reasoning that can arise from emotions, beliefs, or external factors. When individuals possess a strong bias, it can impede their ability to think critically and accurately evaluate information. By being aware of these biases and actively seeking to minimize their influence, one can improve their critical thinking skills and make more accurate judgments.

Problem-Solving and Decision-Making

Finally, the psychological approach to critical thinking also emphasizes the importance of problem-solving and decision-making abilities. Effective problem-solving is accomplished by identifying the problem, gathering and evaluating relevant information, and formulating potential solutions. Strong decision-making skills involve comparing potential solutions and selecting the most effective one based on logical reasoning and evidence.

In conclusion, the psychological approach to critical thinking focuses on fostering cognitive skills, identifying and minimizing biases, and developing strong problem-solving and decision-making abilities. By enhancing these aspects, individuals can become more effective critical thinkers and make well-informed decisions throughout their lives.

Philosophical Groundings

Roots of critical thought.

The roots of critical thought can be traced back to ancient Greek philosophy, particularly the ideas developed by Socrates, Plato, and Aristotle. In their teachings, these philosophers emphasized the importance of questioning and examining beliefs, seeking evidence, and evaluating arguments logically. Through these pursuits, they laid a strong foundation for the development of critical thinking in modern times.

Major Philosophers and Approaches

Several major philosophers and their approaches have significantly contributed to the evolution of critical thinking. Among them, Socrates’ method of inquiry, known as the Socratic Method, involves continuous questioning and probing for deeper understanding. Plato, a student of Socrates, focused on the power of dialectical reasoning, urging individuals to engage in dialogue and debate to examine their own beliefs and the beliefs of others.

Aristotle contributed to critical thinking by emphasizing the importance of logic and coherent reasoning to gain knowledge. He also explored rhetoric, expounding on its role in persuasive argumentation. In more recent times, figures such as John Dewey and Karl Marx have provided insights into the role of critical thinking in education and social transformation.

Informal Logic and its Importance

Informal logic plays a crucial role in critical thinking as it concerns the principles and methods used to analyze everyday arguments and reasoning beyond the scope of formal logic. It complements formal logic, which deals strictly with logical systems and symbols. Informal logic helps individuals assess the validity, soundness, and context of arguments encountered in daily life. By honing their skills in informal logic, individuals can become better critical thinkers and more adept at navigating complex situations and decision-making processes.

Through the teachings of philosophers like Plato, Aristotle, and Socrates, as well as the application of informal logic and logical reasoning, the concept of critical thinking has evolved into an essential aspect of learning and decision-making in modern society. Embracing these foundational elements can empower individuals to develop the skills necessary to think critically and effectively in various aspects of life.

Critical Thinking in Cultural and Social Context

Race and gender perspectives.

Critical thinking is a universal skill that transcends cultural and social boundaries. However, it is essential to consider the impact of race and gender on the development and exercise of critical thinking skills. People from marginalized groups may experience unique challenges and perspectives that influence their critical thinking abilities. For example, in a cross-cultural study examining critical thinking among nurse scholars in Thailand and the United States, distinctive perspectives on critical thinking were observed due to cultural differences. Understanding the intersections of race, gender, and critical thinking can help create more inclusive education and workplace environments that foster critical thinking for everyone.

Critical Thinking in a Democratic Society

In a democratic society, critical thinking plays a crucial role in informed decision-making, civic engagement, and open discussion. The healthy functioning of a democracy relies on the citizens’ capacity to discern reliable information, assess arguments, and make rational choices. According to the Stanford Encyclopedia of Philosophy , critical thinking includes abilities and dispositions that lead individuals to think critically when appropriate. Developing these skills allows members of democratic societies to engage in productive debates, evaluate policies, and hold leaders accountable.

Culture, Society, and Critical Thinking

Cultural backgrounds and societal norms can significantly impact how individuals approach critical thinking. Different cultures may emphasize various ways of thinking, problem-solving, and expressing ideas. As a result, critical thinking can manifest differently across cultures, often influenced by aspects such as language, traditions, and values. A study discussing critical thinking in its historical and social contexts highlights the importance of considering cultural influences when evaluating and teaching critical thinking.

In summary, critical thinking is an essential skill across various cultural, racial, gender, and social contexts. By acknowledging these differences and understanding the significance of critical thinking in democratic societies, educators and societies can promote a more inclusive environment for cultivating critical thinking skills.

Role of Critical Thinking in Education

Aims of education.

The primary aim of education is to foster the development of individuals’ cognitive capabilities, empowering them to grow into confident, knowledgeable and discerning adults. Critical thinking plays a significant role in education as it helps students acquire and apply knowledge more effectively, by analyzing, evaluating, and synthesizing information from diverse sources in a systematic manner, leading to more accurate and informed decisions.

In addition, critical thinking allows students to question existing knowledge and challenge conventional wisdom, thus avoiding indoctrination and promoting intellectual independence. This helps in nurturing open-minded and critical citizens who can contribute positively to society.

Skills Development

Critical thinking involves a variety of skills and abilities that are essential for students’ personal and professional success. These include problem-solving, decision making, logical reasoning, and effective communication, among others. By teaching these skills in the classroom, educators enable learners to confront complex issues and dilemmas with confidence and clarity, fostering their cognitive, social, and emotional growth.

Classroom activities focused on critical thinking are essential to help students develop a systematic approach to problem-solving and sharpen their analytical skills. Practical tasks, like debates, group discussions, case studies, or role plays, can be employed to engage students in active learning, thus enhancing their critical thought processes.

Standardized Tests vs. Critical Thought

While standardized tests have dominated the contemporary education system, there is growing concern regarding their effectiveness in promoting critical thinking. Some argue that standardized tests prioritize the acquisition of specific knowledge over the development of essential skills and abilities, leading to an education that is more focused on rote memorization than meaningful learning.

However, introducing critical thinking elements in the curriculum or classroom activities does not require a complete removal of standardized tests. Educators can strike a balance between knowledge acquisition and skill development by incorporating critical thinking exercises in conjunction with traditional assessments. In doing so, students can better prepare for life beyond the classroom, developing a mindset that values continuous learning, reflection, and intellectual curiosity.

Importance of Open-Mindedness and Skepticism

Being skeptical vs. being cynical.

It is essential to understand the difference between being skeptical and being cynical. Skepticism in critical thinking involves questioning assertions and assumptions, seeking evidence, and evaluating arguments from a neutral, objective viewpoint. On the other hand, cynicism is a distrustful attitude, where one assumes negative intentions or outcomes.

A critical thinker should strive to be skeptical rather than cynical. Approaching situations with skepticism allows for the exploration of different viewpoints and the willingness to change one’s mind based on new evidence, while cynicism can lead to the dismissal of valid arguments due to preconceived negative beliefs.

Traits of an Open-Minded Thinker

Open-mindedness is an essential trait for critical thinkers. Some key characteristics of an open-minded thinker include:

  • Cognitive flexibility : Adapting to and considering new information or perspectives.
  • Tolerance for ambiguity : Accepting the possibility that there may be multiple valid solutions or interpretations.
  • Willingness to change : Being open to revising beliefs and opinions when presented with strong evidence or arguments.

Being open-minded allows critical thinkers to explore various perspectives and ideas and to evaluate them fairly. This inclination towards cognitive flexibility helps in avoiding rigidity in thinking, enabling better decision-making and problem-solving.

Role of Curiosity and Empathy in Critical Thinking

Curiosity and empathy play crucial roles in effective critical thinking. A curious individual seeks knowledge and understanding, thus asking relevant questions and engaging in Socratic questioning. Socratic questioning is a method of probing and analyzing through questions to encourage self-reflection and deeper understanding. This technique fosters critical thinking by challenging assumptions and providing opportunities to explore diverse viewpoints.

Empathy, on the other hand, permits critical thinkers to comprehend and appreciate different perspectives by placing themselves in others’ shoes. An empathetic approach contributes to open-mindedness and cultivates a sense of humility, recognizing that individuals may hold contrasting opinions based on personal experiences or beliefs. The combination of curiosity and empathy enhances critical thinking by promoting a more inclusive and nuanced understanding of complex issues and scenarios.

In the realm of philosophy, critical thinking holds a prominent position. It is a process that revolves around using and assessing reasons to evaluate statements, assumptions, and arguments in ordinary situations. The ultimate goal of critical thinking is to foster good beliefs, aligning them with goals such as truth, usefulness, and rationality 1 .

John Dewey played a crucial role in shaping the concept of critical thinking by introducing it as an educational goal 2 . He connected it with a scientific attitude of mind, highlighting the importance of reflective thought in the process of critical thinking. This approach enhances one’s ability to understand and analyze situations, leading to informed and rational decisions.

Critical thinking equips individuals with the tools necessary to think carefully with clarity, depth, precision, accuracy, and logic 3 . It has applications across various domains, such as science, where great scientists like Albert Einstein have benefited from critical thinking skills to discover groundbreaking concepts.

In conclusion, the philosophy behind critical thinking emphasizes the importance of cultivating a rational and reflective mindset. As an essential skill for problem-solving and decision-making, critical thinking plays a vital role in developing well-rounded individuals ready to navigate the complexities of the world.

From practice in activities such as these, students can begin to become educated speakers of their native language. In learning to speak our native language, we can learn thousands of concepts which, when properly used, enable us to make legitimate inferences about the objects of our experience.

Command of Concepts Requires Insight into Social Conditioning

Unfortunately, overlaid on the logic of language is the logic of the social meanings into which we have been conditioned by the society by which we are raised and from which we take our identity (Italian-American Catholic father, for example). Taking command of these “social” meanings is as large a problem as that of taking command of the logic of educated usage (in our native language). We have a dual problem, then. Our lack of insight into the basic meanings in our native language is compounded by our lack of insight into the social indoctrination we have undergone. Social indoctrination, of course, is a process by which the ideology (or belief system) of a particular group of people is taught to fledgling members of the group in order that they might think as the dominant members of that group do. Education, properly conceived, empowers a person to see-through social indoctrination, freeing them from the shackles of social ideology. They learn to think beyond their culture by learning how to suspend some of the assumptions of thinking within it.

The Journey to Personal Freedom

To move toward personal freedom we must develop the ability to distinguish the concepts and ideas implicit in our social conditioning from the concepts and ideas implicit in the natural language we speak. We must understand the divergent basis for both. For example, people from many different countries and cultures may speak the same natural language. The peoples of Canada, Ireland, Scotland, England, Australia, Canada, and the United States all speak English. By and large they implicitly share (to the extent to which they are proficient in the language) a similar set of basic concepts (that are codified in the 23 volumes of the Oxford English Dictionary). Nevertheless, though sharing this linguistic heritage, these various peoples do not share the same social conditioning. What is more, a person from China or Tibet could learn to speak the English language fluently without in any sense taking in our social indoctrination.

Unfortunately, very few students have sufficient insight into the differences between a natural language and the various cultures that might all use it. They fail to see, therefore, that natural languages — French, German, English, Swahili, or Hindi — are repositories of concepts that, by and large, are not “ideological.” They are not to be equated with the concepts implicit in the social indoctrination fostered by particular social or cultural groups. Indeed, we can use concepts from our native language to critique social indoctrination, just as this article is doing. Command of language makes social critique possible.

In the United States, for example, most people are raised to believe that the U.S. form of economic system (capitalism) is superior to all others. When we are speaking in ideological ways, we call it “free enterprise.” We also often assume (ideologically) that no country can be truly democratic unless it uses an economic system similar to ours. Furthermore, we assume that the major alternative economic systems are either “wrong” or “enslaving” or “evil” (the “evil empire”). We are encouraged to think of the world in this simplistic way by movies, the news, schooling, political speeches, and a thousand other social rituals. Raised in the United States, we internalize different concepts, beliefs, and assumptions about ourselves and the world than we would had we been raised in China or Iran (for example). Nevertheless, no lexicographer would confuse these ideological meanings with the foundational meanings of the words in a bona fide dictionary of the English language. The word "communism" would never be given the gloss of an economic system that enslaves the people. The word "capitalism" would never be given the gloss of an economic system essential to a democratic society.

However, because we are socially conditioned into a self-serving conception of our country, many of our social contradictions or inconsistencies are hidden and go largely unquestioned. Leaving social self-deception undisturbed is incompatible with developing the critical thinking of students. Command of concepts cannot be separated, then, from recognition of when they are, and when they are not, ideologically biased.

The Challenge We Face

If we are committed to helping students think well with concepts, we must teach them how to strip off surface language and consider alternative ways to talk and think about things. This includes teaching them how to closely examine the concepts they have personally formed as well as those into which they have been socially indoctrinated. It means helping students understand that, being fundamentally egocentric, humans tend to be trapped in “private” meanings. Thinking sociocentrically we are trapped in the world-view of our peer group and that of the broader society.

Both set of binders make it hard to rationally decide upon alternative ways to conceptualize situations, persons, and events. Being so trapped, most students are unable to identify or evaluate either meanings in a dictionary or the social rituals, pomp, and glitter of social authority and prestige. Students live their lives, then, on the surface of meaning. They do not know how to plumb the depths.

When we are teaching well, students go beneath the surface. They learn how to identify and evaluate concepts based in natural languages, on the one hand, and those implicit in social rituals and taboos, on the other. They become articulate about what concepts are and how they shape our experience. They can, then, identify key concepts implicit in a communication. They begin to practice taking charge of their ideas and therefore of the life-decisions that those ideas shape and control. Crazy and superficial ideas exist in our society because crazy and superficial thinking has created them. They exist for mass consumption in movies, on television, in the highly marketed “news,” and in the double speak of the ideological world of “law and order.” They do damage everyday to the lives of people.

The challenge to teaching with this end in view is a significant one. It is one we must pursue with a keen sense of the long-term nature of the project and of its importance in the lives of students. We may begin in modest ways for example, with the proper use of the dictionary or how to identify the mores and taboos of one’s peer group — but begin we must, for the quality of the thinking of the students of today determines the quality of the world they shall create tomorrow.

15 Things We Have Learned About Critical Thinking

Here are the key issues to consider in critical thinking..

Posted July 27, 2018

  • What Is Cognition?
  • Find a therapist near me

Not long after the publication of my book, Critical Thinking: Conceptual Perspectives and Practical Guidelines , by Cambridge University Press, Psychology Today contacted me and asked me to write a blog on the subject. I never thought I would write a blog, but when presented with the opportunity to keep sharing my thoughts on critical thinking on a regular basis, I thought, why not ? Maybe my writing might help educators, maybe they might help students and maybe they might help people in their day-to-day decision-making . If it can help, then it’s worthwhile.

To recap, critical thinking (CT) is a metacognitive process, consisting of a number of sub-skills and dispositions, that, when applied through purposeful, self-regulatory, reflective judgment, increase the chances of producing a logical solution to a problem or a valid conclusion to an argument (Dwyer, 2017; Dwyer, Hogan & Stewart, 2014).

CT, if anything, has become more necessary , in this age of information bombardment and the new knowledge economy (Dwyer, Hogan & Stewart, 2014). It allows students to gain a better understanding of complex information (Dwyer, Hogan, & Stewart, 2012; 2014; Gambrill, 2006; Halpern, 2014); it allows them to achieve higher grades and become more employable, informed and active citizens (Barton & McCully, 2007; Holmes & Clizbe, 1997; National Academy of Sciences, 2005); it facilitates good decision-making and problem-solving in social and interpersonal contexts (Ku, 2009); and it decreases the effects of cognitive biases and heuristic -based thinking (Facione & Facione, 2001; McGuinness, 2013).

It’s now been just over a year since I started writing ‘Thoughts on Thinking’. As I consider my thinking and look over my writing during this period, I thought it would be worthwhile to collate and summarise some of the broader learning that has appeared in my writings. So, here’s what we’ve learned:

  • We all know CT is important, but it may be the case that many educators, as well as students, don’t really know what researchers mean by "critical thinking" and/or simply haven’t researched it themselves.
  • Just as many don’t really know what is meant by "critical thinking", there is also the problem of ensuring consistency across how it is defined/conceptualised, trained and measured , which is no easy task.
  • Without adequate training in CT, it may be the case that mature students’ perceptions of how they approach CT do not match their actual ability - despite potentially enhanced autonomy, student responsibility and locus of control , it may be that an over- optimistic outlook on the benefits of experience (and its associated heuristic-based, intuitive judgment) takes centre-stage above and beyond actual ability.
  • Social media is many things: entertainment, education , networking and much more. It is also, unfortunately, a vehicle for promoting faulty thinking. Being able to recognise persuasion techniques, illogical argumentation and fallacious reasoning , will allow you to better assess arguments presented to you, and help you to present better arguments.
  • Values are unique to each and every individual. Though individuals can certainly share values, there is no guarantee that all of an individual’s values overlap with another’s. On the other hand, using the 'virtue' moniker implies that the individual is right based on some kind of ‘moral correctness’. Though there is nothing wrong with an individual presenting ideas and perspectives that they value, it is ill-conceived and dangerous to treat them as global virtues that everyone else should value too.
  • CT is domain-g eneral, but explicit CT training is necessary if educators want to see CT improve and flourish across domains.
  • A person with a strong willingness to conduct CT has the consistent internal willingness and motivation to engage problems and make decisions by using reflective judgment . Reflective judgment, the recognition of limited knowledge and how this uncertainty can affect decision-making processes, is an important aspect of critical thinking regarding ‘taking a step back’ and thinking about an argument or problem a little bit longer and considering the basis for the reasons and consequences of responding in a particular way.
  • There is a need for general, secondary-school training in bias and statistics. We need to teach CT to the coming generations. When not critically thinking, people don’t listen, and fail to be open-minded and reflect upon the information presented to them; they project their opinions and beliefs regardless of whether or not they have evidence to support their claims.
  • Be open-minded towards others. You don’t have to respect them (respect is earned, it’s not a right); but be courteous (sure, we may be in disagreement; but, hey, we’re still civilised people).
  • A person said what they said, not how you interpret what they said. If you are unclear as to what has been said, ask for clarification. Asking for clarity is not a sign of weakness; it is a sign of successful problem-solving.
  • ‘Proof’ is the dirtiest word in critical thinking. Research and science do not prove things, they can only disprove. Be wary when you hear the word ‘prove’ or any of its variants thrown around; but also, be mindful that people feel safer when they are assured and words like ‘proven’ reinforce this feeling of assuredness.
  • Creative thinking isn’t really useful or practical in critical thinking, depending on how you conceptualize it. Critical thinking and creative thinking are very different entities if you treat the latter as something similar to lateral thinking or ‘thinking outside the box’. However, if we conceptualize creative thinking as synthesizing information for the purpose of inferring a logical and feasible conclusion or solution, then it becomes complementary to critical thinking. But then, we are not resorting to creativity alone - all other avenues involving critical thinking must be considered. That is, we can think creatively by synthesizing information we have previously thought about critically (i.e. through analysis and evaluation ) for the purpose of inferring a logical and feasible conclusion or solution. Thus, given this caveat, we can infuse our critical thinking with creative thinking, but we must do so with caution.
  • Changing people’s minds is not easy ; and it’s even more difficult when the person you’re working with believes they have critically thought about it. It may simply boil down to the person you’re trying to educate and their disposition towards critical thinking, but the person’s emotional investment in their stance also plays a significant role.
  • There is no such thing as good or bad CT – you either thought critically or you didn’t. Those who try it in good faith are likely to want to do it ‘properly’; and so, much of whether or not an individual is thinking critically comes down to intellectual humility and intellectual integrity .
  • Finally, there are some general tips that people find useful in applying their critical thinking:
  • Save your critical thinking for things that matter - things you care about.
  • Do it earlier in your day to avoid faulty thinking resulting from decision fatigue.
  • Take a step back and think about a problem a little bit longer, considering the basis for the reasons and consequences of responding in a particular way.
  • Play Devil’s Advocate in order to overcome bias and 'auto-pilot processing' through truly considering alternatives.
  • Leave emotion at the door and remove your beliefs, attitudes, opinions and personal experiences from the equation - all of which are emotionally charged.

  • Description

How the concept of critical thinking emerged, how it has been defined, and how critical thinking skills can be taught.

Critical thinking is regularly cited as an essential twenty-first century skill, the key to success in school and work. Given our propensity to believe fake news, draw incorrect conclusions, and make decisions based on emotion rather than reason, it might even be said that critical thinking is vital to the survival of a democratic society. But what, exactly, is critical thinking? In this volume in the MIT Press Essential Knowledge series, Jonathan Haber explains how the concept of critical thinking emerged, how it has been defined, and how critical thinking skills can be taught and assessed.

Haber describes the term's origins in such disciplines as philosophy, psychology, and science. He examines the components of critical thinking, including structured thinking, language skills, background knowledge, and information literacy, along with such necessary intellectual traits as intellectual humility, empathy, and open-mindedness. He discusses how research has defined critical thinking, how elements of critical thinking have been taught for centuries, and how educators can teach critical thinking skills now.

Haber argues that the most important critical thinking issue today is that not enough people are doing enough of it. Fortunately, critical thinking can be taught, practiced, and evaluated.

to analyze the concept of critical thinking (CT) in Rodger's evolutionary perspective.

documentary research undertaken in the Cinahl, Lilacs, Bdenf and Dedalus databases, using the keywords of 'critical thinking' and 'Nursing', without limitation based on year of publication. The data were analyzed in accordance with the stages of Rodger's conceptual model. The following were included: books and articles in full, published in Portuguese, English or Spanish, which addressed CT in the teaching and practice of Nursing; articles which did not address aspects related to the concept of CT were excluded.

the sample was made up of 42 works. As a substitute term, emphasis is placed on 'analytical thinking', and, as a related factor, decision-making. In order, the most frequent preceding and consequent attributes were: ability to analyze, training of the student nurse, and clinical decision-making. As the implications of CT, emphasis is placed on achieving effective results in care for the patient, family and community.

Conclusion:

CT is a cognitive skill which involves analysis, logical reasoning and clinical judgment, geared towards the resolution of problems, and standing out in the training and practice of the nurse with a view to accurate clinical decision-making and the achieving of effective results.

Introduction

The concept of critical thinking (CT) has, over the last two decades, been one of the most discussed in the area of the teaching and clinical practice of Nursing 1 - 2 .However, as a transversal domain, it extends to the various areas in which people work, from the most simple and routine, to the most complex and painstaking professional and academic tasks 3 - 4 .

The literature on CT has its roots in two academic disciplines: philosophy and psychology 4 - 6 . However, one can also observe a third axis in the field of education 4 , 6 . In philosophy, one seeks to define the hypothetical critical thinker based on her qualities and characteristics 4 , 6 , while psychology seeks to describe the critical thinker based on her skills or actions 4 . In the ambit of education, there is a focus on the teaching and assessment of CT skills. As a result, there is a lack of consensus regarding the concept of CT in the literature, especially in the area of Nursing, which is influenced by these three axes.

In the area of healthcare - including nursing - the aging of the population, the increase in the complexity of illnesses and consequently in the care required, as well as the demand for services, require a professional with skills in CT, problem resolution and decision-making, and who is capable of appropriately accessing information, leading to safe, efficacious clinical practice which is based in scientific evidence 3 , 7 - 8 .

CT is an essential tool for the teaching and care practice of the nurse, and must not be confused with intelligence, but, rather, understood as a skill which can be learned 9 - 10 . This being the case, because of the importance of the need to train professional nurses able to think critically, the Red Iberoamericana de Investigación en Educación en Enfermería (RIIEE) addressed this issue in its multicentric investigation project 11 carried out in 16 countries in Ibero-America, this study being part of this investigation.

Researching CT in conjunction with an international investigation network 11 ) encouraged the authors to undertake the present work, as, as has been observed in the literature in Nursing 4 , 7 , 11 - 12 , the term CT presents variations, causing frequent disagreements, which indicates the need for refining and clarifying the concept. As a result, this study's objective is to analyze the concept of critical thinking in the teaching and clinical practice of Nursing, in the perspective of Rodger's evolutionary model of concept analysis 13 . The rationale for this study of the conceptual analysis of CT, specific to Nursing, is that it promotes clarification for future studies in the ambit of these professionals' academic and clinical practice.

A documentary study 14 ) based on the evolutionary model of concept analysis proposed by Rodgers 13 . This model understands the concept as a reverberation of the phenomena, which are dynamic, as they change over time and have a direct relationship with the context of their use. They have an inductive, nonsequential and descriptive character, indicating systematic rigor, considering a definition which presents conceptual problems 13 .

The process of analysis of the concept took place based on its substitute terms and related concepts, attributes, antecedents, and implications, and involves five stages 13 . In the first stage, the concept of interest was identified 13 , in the present study, CT, including the expressions and substitute terms used for the concept in the literature.

In the second stage, undertaken in February 2015, the authors proceeded to consult with the Cinahl, Lilacs and Bdenf databases 13 , due to these being considered to be important in the context of the Brazilian and foreign scientific production, in the ambit of Nursing. Use was also made of the Dedalus database, for obtaining textbooks of Nursing from the Collective Catalog of the Libraries of the University of São Paulo. As a specific descriptor for CT was not found, the same was inserted in the search as a keyword, along with the descriptor 'Nursing'. The works were identified using the search strategy of critical thinking AND nursing and its variations for Portuguese and Spanish, without limiting the search by year of publication. A total of 529 works were located in the databases mentioned.

In the third stage, for collection of the relevant data, identification of the attributes, and the contextual basis of the concept 13 , the following were defined as inclusion criteria: textbooks and articles of Nursing published in full, published in English, Portuguese or Spanish, and which addressed CT in the teaching and clinical practice of Nursing. The following were defined as exclusion criteria: duplicated studies and those which did not address aspects related to the concept of CT.

In the fourth stage, for analysis of the data and identification of their characteristics 13 , firstly the reading of the titles of the works selected in the second stage was undertaken, based in the criteria of inclusion and exclusion. A total of 481 works was obtained. Next, the abstracts were read in order to select those which addressed the issue of CT in the context of Nursing. Based on this refinement, 47 works were selected, including both books and articles. Following individual and thorough reading of each text in full, a sample of 42 was defined for analysis, including books and articles. At this point, the authors proceeded to reading based on the guiding questions: what are the characteristics/attributes of CT? What are the conditions/means which viabilize CT? What are the consequences of CT? In this stage, through an inductive process, theattributes, antecedents and consequence of the concept, which appeared with the greatest frequency, were identified in the texts. The organization of the stages of the phenomenon analyzed took place through typing, with each characteristic being listed separately, according to the number of authors who addressed it. The data were organized in a Microsoft Office Excel(r) 2013 spreadsheet.

In the fifth stage, implications or hypotheses for continuity of the development of the concept were listed 13 .

Of the 42 works selected for analysis, eight were text books and 34 were articles, with 28 (66.6%) published in English, 12 (28.6%) in Portuguese, and two (4.8%) in Spanish. Of these, the oldest dated from 1997, and the most recent from September 2014: items were included by title, authors, and cataloguing data of the book or periodical ( Figure 1 ). The results below were organized inductively, based on what Rodgers 13 proposes as substitute terms, the attributes, antecedents and consequences, and implications/hypotheses of the concept.

The identification of the substitute terms represents the first approximation with the concept to be analyzed 13 , for understanding the origin, development, functions and interconnections of a concept with other similar words or expressions. The substitute terms for CT identified were: analytical thinking 15 (14.3%), critical-creative thinking 16 (12%), nonlinear thinking 17 (9.5%) and critical-holistic thinking 16 (9.5%).

Differently from the substitute terms, the concepts related to CT ( Table 1 ) have a link and closeness to it, but are not synonymous with it.

CT is characterized by higher-level thinking, which involves knowledge, experiences, dispositions (attitudes or habits of mind) and intellectual abilities. These essential characteristics, or attributes, were identified in the empirical material for analysis as skills and dispositions for CT, and are presented in Table 2 .

The antecedents, like the consequences of a concept, are conditioned to a contextual basis, in this case, the concept of CT in Nursing. In addition to this, they are related to the situational, temporal, sociocultural and course-related contexts of the profession at the present time 13 . The antecedents are considered the events, situations or phenomena which precede the concept investigated, while the consequences are situations which result from the occurrence of the concept in question ( Table 3 ).

The implications and hypotheses represent, respectively, the results and possibilities to be achieved 13 by a critical thinker in the ambit of Nursing and are important aspects for the development of the concept over time 13 . In accordance with the frequency as certained in the works, the implications and hypotheses are listed in Table 4 .

Substitute terms and related factors/concepts

The concept of CT remains little clarified in the Nursing literature 1 , 16 , it being possible to identify a number of close words/expressions which are capable of representing or even explaining attributes and skills of an ideal critical thinker. In this regard, it becomes important to make it clear that substitute terms figure as expressions with meanings which are similar to the concept of CT. This aspect was discussed in one review study 16 , which indicated that clinical reasoning and CT are, often, used as synonymous terms inappropriately, as CT involves skills and attitudes which are necessary for the development of clinical reasoning.

Based on the empirical material researched, the most frequent substitute term was analytical thinking, followed by critical-creative thinking. These substitute terms, to the contrary of clinical reasoning, are synonyms, as they present a semantic interconnection with CT. As a result, when a nurse assesses a patient's health problem, observing, examining, recognizing and raising hypotheses regarding health problems, she is using analytical thinking, which can also be termed CT 17 .

On the other hand, the related factors ( Table 1 ) have a correlation of cause or effect with the concept. For CT, the main related factors identified are aptitudes which are necessary for undertaking the stages of the Nursing process, such as decision-making 16 , clinical judgment 18 - 19 ) and clinical reasoning 11 . This relationship is not one of mere causality, it having been demonstrated in one study 20 that CT skills establish a relationship between themselves and, in the same way, with the stages of the diagnostic process in Nursing. Furthermore, CT involves skills and attitudes which are fundamental for achieving excellent goals of diagnostic accuracy. It is emphasized that, as a structural element of CT, clinical reasoning leads to clinical judgment, resulting in clinical decision-making 12 , 15 , 20 .

Another term which has been described many times coupled with CT, nearly forming a single term, is the concept of reflexive thinking 11 , 15 - 16 . The reasoning for this may be related to the fact that some authors consider reflection to be a skill of the critical thinker. Based on the hypothesis that reflection leads to critical thinking, one experimental study 21 , using reflexive writing, was undertaken with 70 undergraduate students of nursing. As a result, a significant increase was observed in the CT skills among the students of the experimental group. It is, therefore, relevant to undertake studies of this issue, as they assist in the process of understanding and evolution of the concepts.

Generally speaking, the identification of the substitute terms and related factors, respectively, made it possible to broaden the list of synonymous concepts and those which are interrelated. As a result, the related concepts allow the correct application of words which contain within themselves similar philosophical presuppositions, in this case, CT. Besides this, they assist in the understanding of the application of the concept of CT in the context of the practice of the student or nurse, and its importance for diagnostic reasoning, clinical judgment and efficacious decision-making.

Attributes of the concept of CT

The attributes bring together a real definition of the concept, different from the nominal definition provided in dictionaries, which simply substitute one word or expression with another which is synonymous 13 . As a result, the attributes are an integral part of a concept, corresponding to its characteristics. The sum of these attributes typifies and characterizes the concept. As presented in Table 2 , the attributes which qualify CT are made up of skills and dispositions.

It is inferred, based on these results, that in the literature there is a major influence of the Delphi Report 22 , a consensus undertaken at the beginning of the 1990s by an interdisciplinary group of specialists in CT from the area of the humanities, social sciences, and education, defining the essential characteristics of the ideal critical thinker. The report 22 ) describes a significant proportion of the attributes identified in this study, such that these constitute the characteristics examined in most of the psychometric scales for assessing the development of CT.

In the literature analyzed, the skill mentioned most frequently for a critical thinker was "analysis" 11 , 15 , 19 , 22 ) or the ability to break something down in order to achieve an understanding of a given situation. It is believed that this skill is essential in academic and professional activity in Nursing, in that the understanding of the whole is limited to analysis of the parts, whether in the learning of a technique or in taking the patient history.

The most frequent disposition was "open-mindedness" 19 , 22 ) or impartiality in assessment, overcoming preconceptions in a rational way for prudent judgment and later decision-making. However, as studies indicate 4 , 6 , 20 , these skills and dispositions must be constantly exercised, given that the human mind tends to base its decisions on patterns of the cause-and-effect type, often intuitively, without careful examination of the possible alternatives.

As a result, for the improvement in the attributes of CT, the student or professional of Nursing must adopt a stance of seeking, in a careful, rational and active way, the improvement of the cognitive and affective aspects which are inherent to her professional and personal activities 21 , 23 . Based on this definition, it may be perceived that CT is a practical activity based on the sensible search for reason, through skills and dispositions, it being essential for the individual to have an inclination or attitude for carrying these out 20 . In this process, the importance of thinking about thought (metacognition) 4 ) is underlined as a necessary path to developing CT skills.

Antecedents of the Concept

Based on the categories presented in Table 3 , the emphasis on the development of CT in the teaching and training of the student of Nursing is clear 11 , 16 , as well as the importance of the Teaching Policies, in particular the Brazilian National Curricular Guidelines (DCNs)of the undergraduate courses in Nursing 11 , 24 - 25 ) as phenomena which have leveraged the discussions and highlighted the importance of training nurses in the skill of thinking critically.

In Brazil, the DCNs 25 ) bestow curricular flexibility, which viabilizes pedagogical projects geared towards specific goals or demands. As a result, there is the possibility of a teaching permeated by CT, as it progresses towards problematizing training, linking teaching, work and community.

Another aspect also evidenced as a predecessor of CT was the seeking of better results in clinical practice 14 , 18 , 22 ) and the scientific and technological advance 25 - 26 , which represent an important challenge at the time of writing, as a result of the competencies and skills which are necessary and required for the students and nurses in order to respond efficaciously to the complexity of the health systems. In this regard, studies 16 , 19 , 23 indicate that the rapid technological and scientific advances in the area of health, added to the rapid expansion of Nursing's body of knowledge, have required critical thinkers in the profession.

The challenge of training a nurse who is capable of acting in a way that responds to the demands of a society in constant transformation is closely related to the need for cognitive, attitudinal and instrumental development so as to seek better results in practice and in health management 15 , 23 , 27 . Besides this, the nurse's decision-making must take into account the evidence deriving from professional experience, the scientific literature and the patient's requirements, with a view to the safety and quality of the health services.

Consequences of the concept of CT

The consequences of a concept are closely related to the antecedents and must follow them 13 . As a result, the consequences presented in Table 4 are considered to be situations which result from the occurrence of CT. Hence, they trigger actions in practice and/or teaching.

The consequence identified with the highest frequency was "clinical decision-making" 7 , 23 , followed by "clinical judgment" 11 , 19 - 20 ) and "clinical reasoning" 12 , 15 . The latter two, although distinct, are fundamental in the nurse's practice and lead to clinical decision-making. Clinical reasoning involves mental processes applied in the activities of the nurse who, based on a judgment based on knowledge, will take an appropriate decision. In this process of intellectual action, which results in clinical intervention, CT acts as a regulator of the patterns of thinking 8 , 12 . It thus covers an attitude of being disposed to considering, in a conscious way, the problems which arise in the ambit of the clinical experience or of teaching.

For effective decision-making based in CT, therefore, persistent effort is required for examining any situation or supposed form of knowledge in the light of evidence which supports new conclusions in regard to it 10 , 15 . One study 23 ) which assessed the structural elements of CT in 20 nurses from emergency services corroborated these findings, as it emphasized the importance of CT for clinical decision-making, as well as its interconnection in the managerial, multi-professional and teaching ambits. It is relevant to emphasize that the first three consequent terms identified previously also appeared as related concepts in Table 1 , reinforcing the tenuous interconnections with CT.

Implications and hypotheses of the concept of CT

The main implications and hypotheses listed in Table 4 are related to the nurse's care practice. As a result, the most frequent implications for a critical thinker in Nursing were: achieving effective results in care to the patient, family and community 19 , 23 (35.7%) and safety and quality of the care 12 , 16 , 23 (33.3%). Therefore, it is believed that the structural elements of CT (skills and dispositions), continuously exercised in the ambit of nursing, entail effective and safe care. It is inferred that CT can be a mediating instrument in the improvement of reasoning and the exercise of practice, conferring upon the nurse competences and skills for diagnosing accurately.

For this, it is important to consider CT as a process of dynamic and continuous improvement which can be learnt by the nurse. As a result, the improvement of reasoning skills, the constant search for new knowledge, the aim of solving problems and issuing judgments is required, enabling the nurse to predict, diagnose and validate the conclusions obtained, always reviewing these critically 19 , 26 - 27 .

One longitudinal Australian study 28 ) assessed CT skills in 134 students, at two points: upon entering the undergraduate course in Nursing, and three years later, after graduating, using the Health Sciences Reasoning Test. It was concluded that the students significantly increased their CT scores after progressing through the course, principally improving their abilities in analysis and deduction. The students who had the highest scores in the test had better academic performance. These results corroborate the importance of the undergraduate course in helping the students to progress in their CT skills.

As indicated by the works analyzed 15 , 23 , 26 , it is believed that, as she progresses in the dimensions of CT, the student or nurse can achieve greater professional satisfaction and autonomy in her work process. Among various factors analyzed in one study 29 , the nurses reported that they achieved greater professional satisfaction as they achieved greater autonomy. In this regard, CT and its structural elements are intermediary tools which lead the professional to assertiveness in her clinical actions, creating safety, autonomy and satisfaction.

The concept analysis, based in Rodger's evolutionary model, clarified the phenomenon and allowed a correct understanding of CT, with implications for education and care in Nursing.

As antecedents of the concept, emphasis was placed on the need for training in critical thinking while still on the undergraduate course, with a consequent search for better results in clinical practice. This being the case, the main concepts related to CT are those which make up the stages of the Nursing Process, such as decision-making, clinical judgment, and clinical reasoning.

As a result, the understanding of the related factors, attributes, antecedents and consequences of CT made it possible to infer CT as a cognitive skill which involves a process of analysis, logical reasoning and clinical judgment, geared towards problem resolution. From this perspective, it has been emphasized in the training and care practice of the nurse, with a view to accurate clinical decision-making and to achieving effective results in the Nursing interventions for the patient, family and community.

As limitations of the study, the fact is highlighted that studies were selected from Latin American databases, with the exception of Cinahl. However, the study met the needs of the multicentric RIIEE project. As a consequence, broader studies become important, considering that the concept changes over time. Furthermore, it is necessary to develop the clarification of the concept of CT in other areas of knowledge.

The Importance of Critical Thinking Skills for Students

Brains at Work!

If you’re moving toward the end of your high school career, you’ve likely heard a lot about college life and how different it is from high school. Classes are more intense, professors are stricter, and the curriculum is more complicated. All in all, it’s very different compared to high school.

Different doesn’t have to mean scary, though. If you’re nervous about beginning college and you’re worried about how you’ll learn in a place so different from high school, there are steps you can take to help you thrive in your college career.

If you’re wondering how to get accepted into college and how to succeed as a freshman in such a new environment, the answer is simple: harness the power of critical thinking skills for students.

What is critical thinking?

Critical thinking entails using reasoning and the questioning of assumptions to address problems, assess information, identify biases, and more. It's a skillset crucial for students navigating their academic journey and beyond, including how to get accepted into college . At its crux, critical thinking for students has everything to do with self-discipline and making active decisions to 'think outside the box,' allowing individuals to think beyond a concept alone in order to understand it better.

Critical thinking skills for students is a concept highly encouraged in any and every educational setting, and with good reason. Possessing strong critical thinking skills will make you a better student and, frankly, help you gain valuable life skills. Not only will you be more efficient in gathering knowledge and processing information, but you will also enhance your ability to analyse and comprehend it.

Importance of critical thinking for students

Developing critical thinking skills for students is essential for success at all academic levels, particularly in college. It introduces reflection and perspective while encouraging you to question what you’re learning! Even if you’ve seen solid facts. Asking questions, considering other perspectives, and self-reflection cultivate resilient students with endless potential for learning, retention, and personal growth.A well-developed set of critical thinking skills for students will help them excel in many areas. Here are some critical thinking examples for students:

1. Decision-making

If you’re thinking critically, you’re not making impulse decisions or snap judgments; you’re taking the time to weigh the pros and cons. You’re making informed decisions. Critical thinking skills for students can make all the difference.

2. Problem-solving

Students with critical thinking skills are more effective in problem-solving. This reflective thinking process helps you use your own experiences to ideate innovations, solutions, and decisions.

3. Communication

Strong communication skills are a vital aspect of critical thinking for students, helping with their overall critical thinking abilities. How can you learn without asking questions? Critical thinking for students is what helps them produce the questions they may not have ever thought to ask. As a critical thinker, you’ll get better at expressing your ideas concisely and logically, facilitating thoughtful discussion, and learning from your teachers and peers.

4. Analytical skills

Developing analytical skills is a key component of strong critical thinking skills for students. It goes beyond study tips on reviewing data or learning a concept. It’s about the “Who? What? Where? Why? When? How?” When you’re thinking critically, these questions will come naturally, and you’ll be an expert learner because of it.

How can students develop critical thinking skills

Although critical thinking skills for students is an important and necessary process, it isn’t necessarily difficult to develop these observational skills. All it takes is a conscious effort and a little bit of practice. Here are a few tips to get you started:

1. Never stop asking questions

This is the best way to learn critical thinking skills for students. As stated earlier, ask questions—even if you’re presented with facts to begin with. When you’re examining a problem or learning a concept, ask as many questions as you can. Not only will you be better acquainted with what you’re learning, but it’ll soon become second nature to follow this process in every class you take and help you improve your GPA .

2. Practice active listening

As important as asking questions is, it is equally vital to be a good listener to your peers. It is astounding how much we can learn from each other in a collaborative environment! Diverse perspectives are key to fostering critical thinking skills for students. Keep an open mind and view every discussion as an opportunity to learn.

3. Dive into your creativity

Although a college environment is vastly different from high school classrooms, one thing remains constant through all levels of education: the importance of creativity. Creativity is a guiding factor through all facets of critical thinking skills for students. It fosters collaborative discussion, innovative solutions, and thoughtful analyses.

4. Engage in debates and discussions

Participating in debates and discussions helps you articulate your thoughts clearly and consider opposing viewpoints. It challenges the critical thinking skills of students about the evidence presented, decoding arguments, and constructing logical reasoning. Look for debates and discussion opportunities in class, online forums, or extracurricular activities.

5. Look out for diverse sources of information 

In today's digital age, information is easily available from a variety of sources. Make it a habit to explore different opinions, perspectives, and sources of information. This not only broadens one's understanding of a subject but also helps in distinguishing between reliable and biased sources, honing the critical thinking skills of students.

Unlock the power of critical thinking skills while enjoying a seamless student living experience!
