'''Critical thinking''' is the process of analyzing available [[fact]]s, [[evidence]], [[observation]]s, and [[argument]]s to make sound conclusions or informed choices. It involves recognizing underlying assumptions, providing justifications for ideas and actions, evaluating these justifications through comparisons with varying perspectives, and assessing their rationality and potential consequences.<ref>{{Cite book |last=Brookfield |first=Stephen D. |url=https://books.google.com/books?id=CV1pQgAACAAJ&pg=PA13 |title=Developing Critical Thinkers: Challenging Adults to Explore Alternative Ways of Thinking and Acting |date=1987 |publisher=Open University Press |isbn=978-0-335-15551-4 |pages=13–14 |language=en}}</ref> The goal of critical thinking is to form a judgment through the application of [[rational]], [[skepticism|skeptical]], and [[bias|unbiased]] analyses and evaluation.<ref>{{cite web |url = https://www.criticalthinking.org/pages/defining-critical-thinking/766|title=Defining Critical Thinking|publisher=The International Center for the Assessment of Higher Order Thinking (ICAT, US)/Critical Thinking Community|access-date=2017-03-22|author=Edward M.

==History==
[[File:Head of Socrates in Palazzo Massimo alle Terme (Rome).JPG|thumb|In the West, critical reasoning originated from the teachings of the Greek philosopher Socrates (470–399 BC).]]

In the [[Classical Greece|classical period]] (5th c.–4th c. BC) of Ancient Greece, the philosopher [[Plato]] (428–347 BC) indicated that the teachings of [[Socrates]] (470–399 BC) are the earliest records of what today is called critical thinking. In an early dialogue by Plato,{{Citation needed|date=November 2024}} the philosopher Socrates debates several speakers about the [[ethics|ethical]] matter of the rightness or wrongness of Socrates escaping from prison.<ref name=":0">{{Cite book|last1=Visser|first1=Jan|title=Seeking Understanding: The Lifelong Pursuit to Build the Scientific Mind|last2=Visser|first2=Muriel|date=2019|publisher=Brill|isbn=978-90-04-41680-2|location=Leiden|page=233}}</ref> Upon consideration, Plato concluded that to escape prison would violate everything he believes to be greater than himself: the laws of Athens and the guiding voice that Socrates claims to hear.<ref name=":0" />

Socrates established the unreliability of [[Authority]] and of authority figures to possess knowledge and consequent insight; that for an individual man or woman to lead a good life that is worth living, that person must ask critical questions and possess an interrogative soul,<ref>{{Cite book|last1=Stanlick|first1=Nancy A.|title=Asking Good Questions: Case Studies in Ethics and Critical Thinking|last2=Strawser|first2=Michael J.|date=2015|publisher=Hackett Publishing|isbn=978-1-58510-755-1|location=Indianapolis|pages=6}}</ref> which seeks evidence and then closely examines the available facts, and then follows the implications of the statement under analysis, thereby tracing the implications of ''[[Intellectualism|thought]]'' and ''action''.<ref>{{Cite book|last1=Chiarini|first1=Andrea|title=Understanding the Lean Enterprise: Strategies, Methodologies, and Principles for a More Responsive Organization|last2=Found|first2=Pauline|last3=Rich|first3=Nicholas|date=2015|publisher=Springer|isbn=978-3-319-19994-8|location=Cham|pages=132}}</ref>

As a form of co-operative [[argumentation]], [[Socratic questioning]] requires the comparative judgment of facts, which answers then would reveal the person's irrational thinking and lack of verifiable knowledge. Socrates also demonstrated that Authority does not ensure accurate, verifiable knowledge; thus, Socratic questioning analyses beliefs, assumptions, and presumptions, by relying upon evidence and a sound rationale.<ref>{{Cite web|url=http://www.criticalthinking.org/pages/a-brief-history-of-the-idea-of-critical-thinking/408|title=A Brief History of the Idea of Critical Thinking|website=www.criticalthinking.org|access-date=2018-03-14}}</ref>

==Etymology and origin of critical thinking==
In the term ''critical thinking'', the word ''[[wikt:critical|critical]]'', (Grk. κριτικός = ''kritikos'' = "critic") derives from the word ''critic'' and implies a [[critique]]; it identifies the intellectual capacity and the means "of judging", "of judgement", "for judging", and of being "able to discern".<ref>Brown, Lesley.

According to the Oxford English Dictionary, the exact term “critical thinking” first appeared in 1815, in the British literary journal ''The Critical Review'', referring to critical analysis in the literary context. The meaning of "critical thinking" gradually evolved and expanded to mean a desirable general thinking skill by the end of the 19th century and early 20th century.<ref name=":1" />

==Definitions==
Traditionally, critical thinking has been variously defined as follows:

* Thinking about one's thinking in a manner designed to organize and clarify, raise the efficiency of, and recognize errors and biases in one's own thinking. Critical thinking is not 'hard' thinking nor is it directed at solving problems (other than 'improving' one's own thinking). Critical thinking is inward-directed with the intent of maximizing the [[rationality]] of the thinker. One does not use critical thinking to solve problems—one uses critical thinking to improve one's process of thinking.<ref>Carmichael, Kirby; letter to Olivetti, Laguna Salada Union School District, May 1997.</ref>

* Although critical thinking could be defined in several different ways, there is a general agreement in its key component—the desire to reach for a satisfactory result, and this should be achieved by rational thinking and result-driven manner. Halpern thinks that critical thinking firstly involves learned abilities such as problem-solving, calculation and successful probability application. It also includes a tendency to engage the thinking process. In recent times, Stanovich believed that modern IQ testing could hardly measure the ability of critical thinking.<ref>{{Citation|last=Halpern|first=Diane F.|editor3-first=Diane F|editor3-last=Halpern|editor2-first=Henry L|editor2-last=Roediger Iii|editor1-first=Robert J|editor1-last=Sternberg|chapter=The Nature and Nurture of Critical Thinking|pages=1–14|publisher=Cambridge University Press|isbn=9780511804632|doi=10.1017/cbo9780511804632.002|title=Critical Thinking in Psychology|year=2006}}</ref>

Contemporary critical thinking scholars have expanded these traditional definitions to include qualities, concepts, and processes such as creativity, imagination, discovery, reflection, empathy, connecting knowing, feminist theory, subjectivity, ambiguity, and inconclusiveness.  Some definitions of critical thinking exclude these subjective practices.<ref name="Walters1994" /><ref name="Scriven Paul 1987" />

==Logic and rationality==
{{main|Logic and rationality}}
The study of logical argumentation is relevant to the study of critical thinking. Logic is concerned with the analysis of arguments, including the appraisal of their correctness or incorrectness.<ref>{{Cite book|last=Salmon|first=Merrilee H.|title=Introduction to Logic and Critical Thinking, Sixth Edition|date=2013|publisher=Cengage Learning|isbn=978-1-133-04975-3|location=Boston, MA|pages=12}}</ref> In the field of [[epistemology]], critical thinking is considered to be logically correct thinking, which allows for differentiation between logically true and logically false statements.<ref>{{Cite book|last=Sherrie|first=Wisdom|title=Handbook of Research on Advancing Critical Thinking in Higher Education|date=2015|publisher=IGI Global|isbn=978-1-4666-8412-6|location=Hershey, PA|pages=294}}</ref>

In "First wave" logical thinking, the [[Thought|thinker]] is removed from the train of thought, and the analysis of connections between concepts or points in thought is ostensibly free of any bias. In his essay ''Beyond Logicism in Critical Thinking'' [[Kerry S. Walters]] describes this ideology thus: "A logistic approach to critical thinking conveys the message to students that thinking is legitimate only when it conforms to the procedures of informal (and, to a lesser extent, formal) logic and that the good thinker necessarily aims for styles of examination and appraisal that are analytical, abstract, universal, and objective. This model of thinking has become so entrenched in conventional academic wisdom that many educators accept it as canon".<ref name="Walters1994"/> Such principles are concomitant with the increasing dependence on a ''quantitative'' understanding of the world.{{citation needed|date=July 2020}}

In the 'second wave' of critical thinking, authors consciously moved away from the logocentric mode of critical thinking characteristic of the 'first wave'. Although many scholars began to take a less exclusive view of what constitutes critical thinking, rationality and logic remain widely accepted as essential bases for critical thinking. Walters argues that exclusive logicism in the first wave sense is based on "the unwarranted assumption that good thinking is reducible to logical thinking".<ref name="Walters1994"/>

===Deduction, abduction and induction===
[[File:Argument terminology used in logic (en).svg|thumb|500px|right|[[Argument]] terminology used in [[logic]]]]
{{main|logical reasoning}}
There are three types of [[logical reasoning]]. Informally, two kinds of logical reasoning can be distinguished in addition to formal [[Deductive reasoning|deduction]], which are [[inductive reasoning|induction]] and [[abductive reasoning|abduction]].

====Deduction====
* [[Deductive reasoning|Deduction]] is the conclusion drawn from the structure of an argument's [[premises]], by use of [[rules of inference]] formally those of [[propositional calculus]]. For example: X is human and all humans have a face, so X has a face.

====Induction====
* [[Inductive reasoning|Induction]] is drawing a conclusion from a pattern that is guaranteed by the strictness of the structure to which it applies. For example: The sum of even integers is even. Let <math>x,y,z \in \mathbb{Z} </math> then <math>2x,2y,2z</math> are even by definition. If <math>x+y=z</math>, then <math>2x+2y=2(x+y)=2z</math>, which is even; so summing two even numbers results in an even number.

====Abduction====
* [[Abductive reasoning|Abduction]] is drawing a conclusion using a [[heuristic]] that is likely, but not inevitable given some foreknowledge. For example: I observe sheep in a field, and they appear white from my viewing angle, so sheep are white. Contrast with the deductive statement: Some sheep are white on at least one side.

===Critical thinking and rationality===
[[Kerry S. Walters]], an emeritus philosophy professor from [[Gettysburg College]], argues that rationality demands more than just logical or traditional methods of problem solving and analysis or what he calls the "calculus of justification" but also considers "[[cognitive]] acts such as [[imagination]], conceptual creativity, [[intuition]] and insight".<ref name="Walters1994" />{{rp|63}} These "functions" are focused on discovery, on more abstract processes instead of linear, rules-based approaches to problem-solving. The linear and non-sequential mind must both be engaged in the [[rational]] [[mind]].<ref name="Walters1994">{{cite book|author=Kerry S. Walters|title=Re-Thinking Reason: New Perspectives in Critical Thinking|url=https://books.google.com/books?id=TfT32n2Hvd0C|year=1994|publisher=SUNY Press|isbn=978-0-7914-2095-9}}</ref>

The ability to critically analyze an argument — to dissect structure and components, thesis and reasons — is essential. But so is the ability to be flexible and consider non-traditional alternatives and perspectives. These complementary functions are what allow for critical thinking to be a practice encompassing imagination and intuition in cooperation with traditional modes of deductive inquiry.<ref name="Walters1994"/>

==Functions==
The list of core critical thinking skills includes observation, interpretation, analysis, inference, evaluation, explanation, and [[metacognition]]. According to Reynolds (2011), an individual or group engaged in a strong way of critical thinking gives due consideration to establish for instance:<ref>{{cite journal |last1=Reynolds |first1=Martin |journal=Critical Thinking |title=Critical thinking and systems thinking: towards a critical literacy for systems thinking in practice |date=December 2011 |pages=37–68 |url=https://oro.open.ac.uk/30464/ |publisher=Nova Science Publishers |language=en |isbn=978-1-61324-419-7}}</ref>

* Evidence through reality
* Context skills to isolate the problem from context
* Relevant criteria for making the judgment well
* Applicable methods or techniques for forming the judgment
* Applicable theoretical constructs for [[Critical understanding|understanding]] the problem and the question at hand

In addition to possessing strong critical-thinking skills, one must be disposed to engage problems and decisions using those skills. Critical thinking employs not only [[logic]] but broad [[intellect]]ual criteria such as clarity, [[credibility]], [[accuracy]], precision, [[relevance]], depth, [[breadth]], significance, and fairness.<ref>{{cite book|last=Jones|first= Elizabeth A. |year=1995|title= National Assessment of College Student Learning: Identifying College Graduates' Essential Skills in Writing, Speech and Listening, and Critical Thinking. Final Project Report (NCES-95-001)|isbn=978-0-16-048051-5|publisher= National Center on Postsecondary Teaching, Learning, and Assessment, University Park, PA.; Office of Educational Research and Improvement (ED), U.S. Government Printing Office, Superintendent of Documents, Washington, DC PUB TYPE – Reports Research/Technical (143)|pages= 14–15|url=http://files.eric.ed.gov/fulltext/ED383255.pdf|access-date=2016-02-24}}</ref>

Critical thinking calls for the ability to:
* Recognize problems, to find workable means for meeting those problems
* Understand the importance of prioritization and order of precedence in problem-solving
* Gather and marshal pertinent (relevant) information
* Recognize [[unstated assumption]]s and values
* Comprehend and use [[language]] with accuracy, clarity, and [[wikt:discernment|discernment]]
* Interpret data, to appraise evidence and evaluate arguments
* Recognize the existence (or non-existence) of logical relationships between propositions
* Draw warranted conclusions and generalizations
* Put to test the conclusions and generalizations at which one arrives
* Reconstruct one's patterns of beliefs on the basis of wider experience
* Render accurate judgments about specific things and qualities in everyday life

In sum:

"A persistent effort to examine any belief or supposed form of knowledge in the light of the evidence that supports or refutes it and the further conclusions to which it tends."<ref name=glaser>{{Cite book| title=An Experiment in the Development of Critical Thinking| author=Edward M.

Critical thinking is significant in the learning process of [[Internalization (sociology)|internalization]], in the construction of basic ideas, principles, and theories inherent in content.  And critical thinking is significant in the learning process of application, whereby those ideas, principles, and theories are implemented effectively as they become relevant in learners' lives.{{Citation needed|date=November 2020}}

=== In professional fields ===
Critical thinking is an important element of all professional fields and academic disciplines (by referencing their respective sets of permissible questions, evidence sources, criteria, etc.). Within the framework of [[scientific skepticism]], the process of critical thinking involves the careful acquisition and interpretation of information and use of it to reach a [[Justification (epistemology)|well-justified]] conclusion. The concepts and principles of critical thinking can be applied to any context or case but only by reflecting upon the nature of that application. Critical thinking forms, therefore, a system of related, and overlapping, modes of thought such as anthropological thinking, sociological thinking, historical thinking, political thinking, [[psychological]] thinking, philosophical thinking, mathematical thinking, chemical thinking, biological thinking, ecological thinking, legal thinking, ethical thinking, musical thinking, thinking like a painter, sculptor, engineer, business person, etc. In other words, though critical-thinking principles are universal, their application to disciplines requires a process of reflective [[contextualism|contextualization]]. Psychology offerings, for example, have included courses such as Critical Thinking about the [[Paranormal]], in which students are subjected to a series of [[cold reading]]s and tested on their belief of the "psychic", who is eventually announced to be a fake.<ref>{{cite magazine |last1=Baugher |first1=Bob |last2=Haldeman |first2=Philip |date=July–August 2019 |title=Teaching College Students Critical Thinking Skills by Posing as a 'Registered Psychic' |magazine=[[Skeptical Inquirer]] |publisher=[[Center for Inquiry]] |volume=43 |issue=4 |pages=50–52}}</ref>

Critical thinking is considered important in the academic fields for enabling one to analyze, evaluate, explain, and restructure thinking, thereby ensuring the act of thinking without false belief. However, even with knowledge of the methods of logical inquiry and reasoning, mistakes occur, and due to a thinker's inability to apply the methodology consistently, and because of overruling character traits such as [[egocentrism]]. Critical thinking includes identification of [[prejudice]], [[bias]], propaganda, self-deception, distortion, [[misinformation]], etc.<ref>{{cite web |url=http://philosophy.hku.hk/think/fallacy/biases.php |title=[F08] Cognitive biases |last1=Lau |first1=Joe |last2=Chan |first2=Jonathan |website=Critical thinking web |access-date=2016-02-01 }}</ref> Given research in [[cognitive psychology]], some [[education|educators]] believe that schools should focus on teaching their students critical-thinking [[skill]]s and cultivation of intellectual traits.<ref>{{cite web |url = http://www.criticalthinking.org/pages/critical-thinking-moral-integrity-and-citizenship-teaching-for-the-intellectual-virtues/487 |title=Critical Thinking, Moral Integrity and Citizenship |website=Criticalthinking.org |access-date=2016-02-01 }}</ref>

Critical-thinking skills can be used to help nurses during the assessment process. Through the use of critical thinking, nurses can question, evaluate, and reconstruct the nursing care process by challenging the established theory and practice. Critical-thinking skills can help nurses problem solve, reflect, and make a conclusive decision about the current situation they face. Critical thinking creates "new possibilities for the development of the nursing knowledge".<ref>{{cite journal | doi = 10.1046/j.1365-2648.1999.00925.x | volume=29 | title=Catching the wave: understanding the concept of critical thinking | year=1999 | journal=Journal of Advanced Nursing | pages=577–583 | last1 = Boychuk Duchscher | first1 = Judy E.| issue=3 | pmid=28796334 }}</ref> Due to the sociocultural, environmental, and political issues that are affecting healthcare delivery, it would be helpful to embody new techniques in nursing. Nurses can also engage their critical-thinking skills through the Socratic method of dialogue and reflection. This practice standard is even part of some regulatory organizations such as the College of Nurses of Ontario's Professional Standards for Continuing Competencies (2006).<ref>College of Nurses of Ontario – Professional Standards for
[http://www.cno.org/Global/4-LearnAboutStandardsAndGuidelines/prac/learn/modules/profstands/slides/Competence.pdf Continuing Competencies (2006)] {{Webarchive|url=https://web.archive.org/web/20140912093242/http://www.cno.org/Global/4-LearnAboutStandardsAndGuidelines/prac/learn/modules/profstands/slides/Competence.pdf |date=12 September 2014 }}</ref> 
It requires nurses to engage in [[Reflective Practice]] and keep records of this continued professional development for possible review by the college.

==Habits or traits of the mind==
The habits of [[mind]] that characterize a person strongly disposed toward critical thinking include a desire to follow reason and evidence wherever they may lead, a systematic approach to problem-solving, [[inquisitiveness]], even-handedness, and confidence in [[reasoning]].<ref>The National Assessment of College Student Learning: Identification of the Skills to be Taught, Learned, and Assessed, NCES 94–286, US Dept of Education, Addison Greenwood (Ed), Sal Carrallo (PI). See also, Critical thinking: A statement of expert consensus for purposes of educational assessment and instruction. ERIC Document No. ED 315–423</ref>

According to a definition analysis by Kompf & Bond (2001), critical thinking involves problem-solving, decision making, [[metacognition]],<ref>{{Cite web|url=https://serc.carleton.edu/NAGTWorkshops/metacognition/teaching_metacognition.html|title=Teaching Metacognition|website=Metacognition|access-date=2018-04-03}}</ref> rationality, rational thinking, [[reason]]ing, [[knowledge]], [[intelligence]] and also a moral component such as reflective thinking. Critical thinkers therefore need to have reached a level of maturity in their development, possess a certain attitude as well as a set of taught skills.

There is a postulation by some writers that the tendencies from habits of mind should be thought as virtues to demonstrate the characteristics of a critical thinker.<ref>{{Cite journal|last1=Facione|first1=Peter A.|last2=Sánchez|first2=Carol A.|last3=Facione|first3=Noreen C.|last4=Gainen|first4=Joanne|date=1995|journal=The Journal of General Education|volume=44|issue=1|pages=1–25|issn=0021-3667|jstor=27797240|title=The Disposition Toward Critical Thinking}}</ref> These [[intellectual virtue]]s are ethical qualities that encourage motivation to think in particular ways towards specific circumstances. However, these virtues have also been criticized by skeptics who argue that the evidence is lacking for a specific mental basis underpinning critical thinking.<ref>{{Cite journal|last1=Bailin|first1=Sharon|last2=Case|first2=Roland|last3=Coombs|first3=Jerrold R.|last4=Daniels|first4=Leroi B.|date=May 1999|title=Common misconceptions of critical thinking|journal=Journal of Curriculum Studies|language=en|volume=31|issue=3|pages=269–283|doi=10.1080/002202799183124|issn=0022-0272}}</ref>

==Teaching critical thinking==
[[John Dewey]] is one of many educational leaders who recognized that a curriculum aimed at building thinking skills would benefit the individual learner, the community, and [[democracy]].<ref>Dewey, John. (1910). ''How we think''. Lexington, MA: D.C. Heath & Co.{{page needed|date=February 2022}}</ref>

In a 2014 meta-analysis, researchers reviewed 341 quasi- or true-experimental studies of teaching critical thinking, all of which used some form of standardized critical-thinking measure.<ref name="o326">{{cite journal | last=Abrami | first=Philip C. | last2=Bernard | first2=Robert M. | last3=Borokhovski | first3=Eugene | last4=Waddington | first4=David I. | last5=Wade | first5=C. Anne | last6=Persson | first6=Tonje | title=Strategies for Teaching Students to Think Critically: A Meta-Analysis | journal=Review of Educational Research | volume=85 | issue=2 | date=2015 | issn=0034-6543 | doi=10.3102/0034654314551063 | pages=275–314}}</ref> The authors describe the various methodological approaches and attempt to categorize differing assessment tools, which include standardized tests (and second-source measures), tests developed by teachers, tests developed by researchers, and tests developed by teachers who also serve the role as the [[research]]er. The results emphasized the need for exposing students to real-world problems and the importance of encouraging open dialogue within a supportive environment. Effective strategies for teaching critical thinking are thought to be possible in a wide variety of [[education]]al settings.<ref name="o326"/> One attempt to assess the [[humanities]]' role in teaching critical thinking and reducing belief in [[Pseudoscience|pseudoscientific]] claims was made at [[North Carolina State University]]. Some success was noted and the researchers emphasized the value of the humanities in providing the skills to evaluate current events and qualitative data in context.<ref>{{cite journal |last = Frazier |first = Kendrick |author-link = Kendrick Frazier |title = Humanities, Too: In New Study, History Courses in Critical Thinking Reduce Pseudoscientific Beliefs |journal=[[Skeptical Inquirer]] |year = 2017 |volume=41 |issue=4 |page=11 }}</ref>

Historically, the teaching of critical thinking focused only on logical procedures such as formal and informal logic.{{Citation needed|date=November 2020}} This emphasized to students that good thinking is equivalent to logical thinking. However, a second wave of critical thinking, urges educators to value conventional techniques, meanwhile expanding what it means to be a critical thinker. In 1994, Kerry Walters<ref name="Walters1994" /> compiled a conglomeration of sources surpassing this logical restriction to include many different authors' research regarding connected knowing, empathy, gender-sensitive ideals, collaboration, world views, intellectual autonomy, morality and enlightenment. These concepts invite students to incorporate their own perspectives and experiences into their thinking. 
[[Scott Lilienfeld]] notes that there is some evidence to suggest that basic critical-thinking skills might be successfully taught to children at a younger age than previously thought.<ref>{{cite journal |last=Lilienfeld |first=Scott |author-link = Scott Lilienfeld |title=Teaching Skepticism: How Early Can We Begin? |journal=[[Skeptical Inquirer]] |year=2017 |volume=41 |issue=5 |pages=30–31 |url = https://www.csicop.org/si/show/teaching_skepticism_how_early_can_we_begin |archive-url = https://web.archive.org/web/20180810182835/https://www.csicop.org/si/show/teaching_skepticism_how_early_can_we_begin |url-status=dead |archive-date=2018-08-10 }}</ref>

In the English and Welsh school systems, ''Critical Thinking'' is offered as a subject that 16- to 18-year-olds can take as an [[Advanced Level (UK)|A-Level]].

=== Well-educated citizens ===
{{See also|Citizenship education (subject)}}
In 1995, a meta-analysis of the literature on teaching effectiveness in higher [[education]] noted concerns that higher education was failing to meet society's requirements for well-educated citizens. It concluded that although faculty may aspire to develop students' [[Thought|thinking]] skills, in practice they have tended to aim at facts and concepts utilizing lowest levels of [[cognition]], rather than developing intellect or [[Value (ethics and social sciences)|values]].<ref>Lion Gardiner, Redesigning Higher Education: Producing Dramatic Gains in Student Learning, in conjunction with: ERIC Clearinghouse on Higher Education, 1995</ref>

Critical thinking is also considered important for [[human rights education]] for [[toleration]]. The [[International Day for Tolerance|Declaration of Principles on Tolerance]] adopted by [[UNESCO]] in 1995 affirms that "education for tolerance could aim at countering factors that lead to fear and exclusion of others, and could help young people to develop capacities for independent judgement, ''critical thinking'' and ethical [[reason]]ing".<ref>{{cite web |website = UNESCO |title=International Day for Tolerance . Declaration of Principles on Tolerance, Article 4, 3 |url = http://portal.unesco.org/en/ev.php-URL_ID=13175&URL_DO=DO_TOPIC&URL_SECTION=201.html |access-date = 2016-02-24 }}</ref>

==Assessment of critical thinking==
Under the [[OCR (exam board)|OCR]] [[exam board]], students can sit two exam papers for the Advanced Subsidiary: "Credibility of Evidence" and "Assessing and Developing Argument". The full Advanced [[General Certificate of Education|GCE]] is now available: in addition to the two Advanced Subsidiary units, candidates sit the two papers "Resolution of Dilemmas" and "Critical Reasoning". The A-level tests candidates on their ability to think critically about, and analyze, arguments on their deductive or inductive validity, as well as producing their own arguments. It also tests their ability to analyze certain related topics such as credibility and ethical decision-making. However, due to its comparative lack of subject content, many universities do not accept it as a main A-level for admissions.<ref>[http://www.ocr.org.uk/qualifications/asa_levelgceforfirstteachingin2008/critical_thinking/faqs.html Critical Thinking FAQs from Oxford Cambridge and RSA Examinations] {{webarchive |url = https://web.archive.org/web/20080411150135/http://www.ocr.org.uk/qualifications/asa_levelgceforfirstteachingin2008/critical_thinking/faqs.html |date=11 April 2008 }}</ref> Nevertheless, the Advanced Subsidiary is often useful in developing reasoning skills, and the full Advanced GCE is useful for degree courses in politics, philosophy, history or [[theology]], providing the skills required for critical analysis that are useful, for example, in biblical study.

There used to also be an [[Advanced Extension Award]] offered in Critical Thinking in the UK, open to any A-level student regardless of whether they have the Critical Thinking A-level. [[Cambridge International Examinations]] have an A-level in Thinking Skills.<ref>{{cite web|url=http://www.cie.org.uk/qualifications/academic/uppersec/alevel/subject/aleveldetails?assdef_id=765_804|title=Cambridge International AS and A Level subjects}}</ref>

From 2008, [[Assessment and Qualifications Alliance]] has also been offering an A-level Critical Thinking specification.<ref>[http://www.aqa.org.uk/qual/gce/critical_thinking_new.php "New GCEs for 2008"], Assessment and Qualifications Alliance {{webarchive |url=https://web.archive.org/web/20080217221100/http://www.aqa.org.uk/qual/gce/critical_thinking_new.php |date=17 February 2008 }}</ref>
[[OCR (exam board)|OCR]] [[exam board]] have also modified theirs for 2008. Many examinations for university entrance set by universities, on top of A-level examinations, also include a critical-thinking component, such as the [[LNAT]], the [[UKCAT]], the [[BioMedical Admissions Test]] and the [[Thinking Skills Assessment]].

In [[Qatar]], critical thinking was offered by [[Al-Bairaq]] - an outreach, non-traditional educational program that targeted [[high school student]]s and focussed on a curriculum based on [[STEM fields]]. The idea behind this was to offer high school students the opportunity to connect with the research environment in the Center for Advanced Materials (CAM) at Qatar University. Faculty members train and mentor the students and help develop and enhance their critical thinking, problem-solving, and teamwork skills.<ref>{{cite web |url = http://www.qu.edu.qa/offices/research/CAM/dmsprogram/index.php |access-date=5 July 2014 |url-status=dead |archive-url = https://web.archive.org/web/20140419220638/http://www.qu.edu.qa/offices/research/CAM/dmsprogram/index.php |title = Welcome to Al-Bairaq World |archive-date=19 April 2014 }}</ref>{{failed verification |date=November 2016 }}

==Research of critical thinking==
After undertaking research in schools, Edward M. Glaser proposed in 1941 that the ability to think critically involves three elements:<ref name=glaser/>
# An attitude of being disposed to consider in a thoughtful way the problems and subjects that come within the range of one's experiences
# Knowledge of the methods of logical [[inquiry]] and reasoning
# Some skill in applying those methods.<ref name=glaser/>

The Critical Thinking project at Human Science Lab, [[London]], is involved in the scientific study of all major [[educational system]]s in prevalence today to assess how the systems are working to promote or impede critical thinking.<ref>{{cite web | url= http://humansciencelab.org.uk/research/| title=Research at Human Science Lab |publisher=Human Science Lab | access-date=5 March 2017}}</ref>

Contemporary cognitive psychology regards human reasoning as a complex process that is both reactive and reflective.<ref>Solomon, S.A. (2002) "Two Systems of Reasoning", in ''Heuristics and Biases: The Psychology of Intuitive Judgment'', Govitch, Griffin, Kahneman (Eds), Cambridge University Press. {{ISBN|978-0-521-79679-8}}; ''Thinking and Reasoning in Human Decision Making: The Method of Argument and Heuristic Analysis'', Facione and Facione, 2007, California Academic Press.  {{ISBN|978-1-891557-58-3}}</ref> This presents a problem that is detailed as a division of a critical mind in juxtaposition to sensory data and memory.

The psychological theory disposes of the absolute nature of the rational mind, in reference to conditions, abstract problems and discursive limitations. Where the relationship between critical-thinking skills and critical-thinking dispositions is an empirical question, the ability to attain causal domination exists, for which Socrates was known to be largely disposed against as the practice of [[Sophist]]ry. Accounting for a measure of "critical-thinking dispositions" is the California Measure of Mental Motivation<ref>[https://books.google.com/books?id=OT12dZ0binIC&pg=PA46 ''Research on Sociocultural Influences on Motivation and Learning''], p. 46</ref> and the California Critical Thinking Dispositions Inventory.<ref>{{cite journal|last=Walsh|first=Catherine, M.|year=2007|title=California Critical Thinking Disposition Inventory: Further Factor Analytic Examination|journal= Perceptual and Motor Skills|volume=104|issue=1|pages=141–151|doi=10.2466/pms.104.1.141-151|pmid=17450973|s2cid=44863676}}</ref> The Critical Thinking Toolkit is an alternative measure that examines student beliefs and attitudes about critical thinking.<ref>Stupple, E. J. N., Maratos, F. A., Elander, J., Hunt, T. E., Cheung, K. Y., & Aubeeluck, A. V. (2017). "Development of the Critical Thinking Toolkit (CriTT): A measure of student attitudes and beliefs about critical thinking". ''Thinking Skills and Creativity'', 23, 91–100.</ref>

==Online communication==
The advent and rising popularity of online courses have prompted some to ask if computer-mediated communication promotes, hinders, or has no effect on the amount and quality of critical thinking in a course (relative to face-to-face communication). There is some evidence to suggest a fourth, more nuanced possibility: that online communication may promote some aspects of critical thinking but hinder others. For example, Guiller et al. (2008)<ref name="Guiller2008">{{cite journal|last1=Guiller|first1=Jane|last2=Durndell|first2=Alan|last3=Ross|first3=Anne|title=Peer interaction and critical thinking: Face-to-face or online discussion?|journal=Learning and Instruction|year=2008|volume=18|issue=2|pages=187–200|doi=10.1016/j.learninstruc.2007.03.001}}</ref> found that, relative to face-to-face discourse, online discourse featured more justifications, while face-to-face discourse featured more instances of students expanding on what others had said. The increase in justifications may be due to the asynchronous nature of online discussions, while the increase in expanding comments may be due to the spontaneity of 'real-time' discussion. Newman et al. (1995)<ref name="Newman1995">{{cite journal |last1=Newman |first1 = D. R. |last2=Webb|first2=Brian|last3=Cochrane|first3=Clive|title = A content analysis method to measure critical thinking in face-to-face and computer-supported group learning|journal=Interpersonal Computing and Technology|year=1995|volume=3|issue=September 1993|pages=56–77|doi=10.1111/j.1365-2648.2007.04569.x|pmid=18352969|hdl = 10818/15120 |s2cid = 14308899 |hdl-access=free}}</ref> showed similar differential effects. They found that while online communications boasted more important statements and linking of ideas, it lacked novelty. The authors suggest that this may be due to difficulties participating in a brainstorming-style activity in an asynchronous environment. Rather, the asynchrony may promote users to put forth "considered, thought out contributions".

Researchers assessing critical thinking in online discussion forums often employ a technique called Content Analysis,<ref name="Newman1995" /><ref name="Guiller2008" /> where the text of online discourse (or the transcription of face-to-face discourse) is systematically coded for different kinds of statements relating to critical thinking. For example, a statement might be coded as "Discuss ambiguities to clear them up" or "Welcoming outside knowledge" as positive indicators of critical thinking. Conversely, statements reflecting poor critical thinking may be labeled as "Sticking to prejudice or assumptions" or "Squashing attempts to bring in outside knowledge". The frequency of these codes in online communication and face-to-face discourse can be compared to draw conclusions about the quality of critical thinking.

Searching for evidence of critical thinking in discourse has roots in a definition of critical thinking put forth by Kuhn (1991),<ref name="Kuhn1991">{{cite book|last1=Kuhn|first1=D|title=The skills of argument|date=1991|publisher=Cambridge University Press|location=Cambridge, UK}}</ref> which emphasizes the social nature of discussion and knowledge construction. There is limited research on the role of social experience in critical thinking development, but there is some evidence to suggest it is an important factor. For example, research has shown that three- to four-year-old children can discern, to some extent, the differential credibility<ref name="Koenig2005">{{cite journal|last1=Koenig|first1=M A|last2=Harris|first2=P L|title=Preschoolers mistrust ignorant and inaccurate speakers|journal=Child Development|date=2005|volume=76|issue=6|pages=1261–1277|doi=10.1111/j.1467-8624.2005.00849.x|pmid=16274439|citeseerx=10.1.1.501.253}}</ref> and expertise<ref name="Lutz2002">{{cite journal|last1=Lutz|first1=D J|last2=Keil|first2=F C|title=Early understanding of the division of cognitive labor|journal=Child Development|date=2002|volume=73|issue=4|pages=1073–1084|doi=10.1111/1467-8624.00458|pmid=12146734}}</ref> of individuals. Further evidence for the impact of social experience on the development of critical-thinking skills comes from work that found that 6- to 7-year-olds from China have similar levels of skepticism to 10- and 11-year-olds in the United States.<ref name="Heyman2007">{{cite journal|last1=Heyman|first1=G D|last2=Fu|first2=G|last3=Lee|first3=K|title=Evaluating claims people make about themselves: The development of skepticism|journal=Child Development|year=2007|volume=78|issue=2|pages=367–375|doi=10.1111/j.1467-8624.2007.01003.x|pmid=17381778|pmc=2570105}}</ref> If the development of critical-thinking skills was solely due to maturation, it is unlikely we would see such dramatic differences across cultures.
