Overview of Critical Thinking

What is the Thinking Process?
* Senses provide our bodies with sensations which they pick up from the outside world. These sensations are transmitted by nerves to the biological structures which will translate them.
* Biological--the sensations provided by the senses are inputted by nerves to the brain which then translates, decodes and encodes messages and sends them out through the nervous system.
* Psychological--takes the messages from the brain and translates them into perceptions and reactions.
* Cognitive--translations through the biological and psychological dimensions of the thinking process of the perceptions and reactions into concepts, ideas, assumptions, suppositions, inferences, hypotheses, questions, beliefs, premises, logical arguments, etc.
* Communications--takes the messages from the brain and translates them into verbal, non-verbal and written language to communicate the thoughts and ideas which were generated.
Stages of Cognitive Development as Defined by Jean Piaget:
* Birth to 2 years old--no thinking structures (called schemas) and starts to develop such schemas through exploration of senses and experimentation with environment.
* Preoperational Stage: 2 to 7 years old--develop language skills and more sophisticated cognitive structures but still is prelogical.
o Not capable of conservation-ability to understand that substance does not change although it changes shape or form
o Incapable of decentering-ability to see things from another perspective
* Concrete Operational Stage: 7 years to Adolescence--begin to grasp conservation and decentering. Begins to question life. Solves problems, but haphazardly.
* Formal Operations Stage: Adolescence and onward--now capable of sophisticated logical thought. Can think in abstract. Can think hypothetically and solve problems using the logic of combinations.
Note: Many theorists postulate a fifth stage:
* Dialectical reasoning--stage beyond logic where critical thinking lies. Ability to perceive the frequent paradoxes in life and question and analyze the assumptions that underlie logic.
What Is Critical Thinking?
Critical thinking consists of three steps:
* 1. Becoming aware that assumptions exist
* 2. Making assumptions explicit
* 3. Assessing their accuracy
o Do these assumptions make sense?
o Do these assumptions fit reality as we understand and live it?
o Under what conditions do these assumptions seem to hold true? Under what conditions do they seem false?
Misconceptions About Critical Thinking
* It is wholly a negative process-it tears down ideas and puts nothing in their place (rather it is a positive process to put things in a more realistic perspective).
* It will lead to relativistic freeze--the inability to make commitments to people, ideas, structures (rather. commitments are informed ones).
* It seems to involve traumatic change-one is expected to abandon old assumptions continually. (rather: Some beliefs stay the same--they are simply more informed).
* It is dispassionate and cold (it is rather highly emotive and liberating to be free of past assumptions and the anxiety of self-scrutiny).
Why Is Critical Thinking Important?
* All actions, decisions and judgments spring from assumptions--if they are unchecked or inappropriate, we will make poor decisions and wrong judgments.
* In personal relationships we learn to keep our lines of communications open-we avoid uncritically reproducing patterns of the modeled interactions we learned from our parental interaction.
* In the workplace we avoid stagnation and atrophy and are willing to challenge the current paradigms which are uncritically accepted and may have come down in the workplace from a time and thinking which is no longer relevant to our current reality.
What Does the Absence of Thinking Critically Look Like?
* We blindly reproduce the damaging reactions we have learned.
* We blindly accept at face value all justifications given by organizations and political leaders.
* We blindly believe TV commercials.
* We blindly trust political commercials.
* We blindly accept and say that if the textbook says it it must be so.
* We blindly accept and say that if the organization does it it must be right.
What Does Critical Thinking Look Like?
* Contextual sensitivity--being sensitive to stereotypes about people from a particular group and trying to accept others at face value unconditionally
* Perspective thinking--trying to get into the other person's head, or walking in the other person's shoes so as to see the world the way that person sees and perceives the world.
* Tolerance for ambiguity--ability to accept multiple interpretations of the same situation
* Alert to premature ultimatums--invoking a powerful idea or concept which inspires such reverence that any further debate is forestalled. E.g., a politician invokes "democracy."
Characteristics of People who Excel at Critical Thinking
Truth seeking: A courageous desire for the best knowledge, even if such knowledge fails to support or undermines one's preconceptions, beliefs or self-interests.
Open-mindedness: Tolerance to divergent views, self-monitoring for possible bias.
Analyticity: Demanding the application of reason and evidence, alert to problematic situations, inclined to anticipate consequences.
Systematicity: Valuing organization, focus and diligence to approach problems of all levels of complexity.
Critical Thinking Self-Confidence: Trusting of one's own reasoning skills and seeing oneself as a good thinker.
Inquisitiveness: Curious and eager to acquire knowledge and learn explanations even when the applications of the knowledge are not immediately apparent.
Cognitive Maturity: Prudence in making, suspending or revising judgment. An awareness that multiple solutions can be acceptable. An appreciation of the need to reach closure even in the absence of complete knowledge.
These characteristics are measured by California Critical Thinking Dispositions Inventory: www.calpress.com/cctdi.html.
What Are the Major Components in Critical Thinking?
* Perception
* Assumptions
* Emotion
* Language
* Argument
* Fallacy
* Logic
* Problem Solving
Perception
* The way we receive and translate our experience.
* Also a significant filtering system.
* How we perceive defines how we think.

* Mind Benders: Can You Trust Your Perceptions.
* Stories from Email Posting To Test Your Critical Thinking: Perceptions.
Assumptions
* Central to Critical Thinking
* Implied, not conscious of them
* Not always bad
* Rest on notion some ideas are obvious
* Make us comfortable with present beliefs and shut out alternatives
For more information on this site about assumptions see:
* Stories from Email Posting To Test Your Critical Thinking: Assumptions
Emotion
* Trying to "leave emotion out of it" is Impossible.
* Part of everything we do and think.
* Personal barriers are a given.
* Critical thinker don't ignore or deny emotions; accept and manage them.
Language
* Thinking can't be separated from.
* Three primary purposes: inform, persuade and explain.
* Language denotes and connotes.
* Metaphors.
For more information on this site about language see:
* Stories from Email Posting To Test Your Critical Thinking: Language.
Metaphors
Metaphors are powerful language tools that influence how we think and problem solve. Metaphors are figures of speech which can give great color and depth to our language. Metaphors can be short phrases, stories or poems. A metaphor is a verbal message which can be easily visualized by the reader or listener.
For more information on this site about metaphors see:
* Stories from Email Posting To Test Your Critical Thinking: Metaphors.
Argument
* Claim, used to persuade that something is (or not) true or should (or not) be done
* Contains three basic elements
o Issue
o One or more reasons (premises)
o One or more conclusions
* Can be valid or invalid based on structure
* Only premises and conclusions true or false
* Goal of Critical Thinking is sound arguments
* Valid (proper structure)
* With true premises
* Sound argument has both: so the conclusion must be true
* Therein the beauty and usefulness of logic
Fallacy
* Reasoning that doesn't meet criteria for sound argument is fallacious
* Valid
* True premises
* Complete (all relevant information)
* Fallacy is incorrect pattern of reasoning
* Does not always mean conclusion is false
* Ads and editorials
Logic
Two methods of reasoning:
Deductive
* Facts, certainty, syllogisms, validity, truth of premises sound arguments and conclusions
Inductive
* Diverse facts, probabilities, generalizations, hypotheses, analogies
Problem Solving
* Logic problems like any problem
* Techniques:
* Understand the problem
* Identify unknowns and knowns
* Relationships between these (visual aids)
* Generate strategy from step above
* Apply and solve; repeat if necessary

Requirements for Effective Critical Thinking
Six Cognitive Skills
* Interpretation
* Analysis
* Evaluation
* Inference
* Explanation
* Self-regulation
Interpretation
* Comprehend and express meaning or significance of wide variety of experiences, situations, data, events, judgments, conventions, beliefs, rules, procedures or criteria.
Analysis
* Identify the intended and actual inferential relationships among statements, questions, concepts, descriptions or other forms of representation intended to express belief, judgment, experiences, reasons, information or opinion.
Evaluation
* Assess the credibility of statements or other representations which are accounts or descriptions of a person's perception, experience, situation, judgment, belief or opinion; and to assess the logical strength of the actual or intended inferential relationships among statements, descriptions, questions or other forms of representation.
Inference
* Identify and secure elements needed to draw reasonable conclusions; to form conjectures and hypotheses; to consider relevant information and to educe the consequences flowing from data, statements, principles, evidence, judgments, beliefs, opinions, concepts, descriptions, questions or other forms of representation.
Explanation
* State the results of one's reasoning; justify that reasoning in terms of evidential, conceptual, methodological, criteriological and contextual considerations upon which one's results were based; and to present one's reasoning in the form of cogent arguments.
Self-regulation
* Self-consciously to monitor one's cognitive activities, the elements used in those activities and the results deduced, particularly by applying skills in analysis and evaluation to one's own inferential judgments with a view toward questions, confirming, validation or correcting either one's reasoning or results..
Affective Dispositions
* Something else is needed.
* More to Critical Thinking than just cognitive skills.
* Human beings more than just thinking machines.
* "the Critical Spirit" (affective dispositions).
* A probing inquisitiveness.
* A keenness of mind.
* A zealous dedication to reason.
* A hunger or eagerness for reliable information.
Critical Thinking is:
* How you approach problems, questions and issues.
* The best way we know to get to the truth.
* Experts conclude: Critical Thinking is a pervasive, purposeful human phenomenon.
* Ideal critical thinker characterized also by how he approaches life and living in general.
Approaches to life characterizing good Critical Thinking:
* Inquisitiveness about wide range of issues.
* Concern to become and stay well-informed.
* Alertness to opportunities to use Critical Thinking.
* Self-confidence in one's abilities to reason.
* Open-mindedness about divergent world views.
* Flexibility in considering alternatives and opinions.
* Understanding the opinions of other people.
* Fair-mindedness in appraising reasoning.
* Honesty in facing one's own biases, prejudices, stereotypes, egocentric and sociocentric tendencies.
* Prudence in suspending, making, altering judgments.
* Willingness to reconsider and revise views.
* Clarity in stating question or concern.
* Orderliness in working with complexity.
* Diligence in seeking relevant information.
* Reasonableness in selecting and applying criteria.
* Care in focusing attention on the concern at hand.
* Persistence through difficulties.
* Precision to the degree permitted by subject and circumstances.
Value of Critical Thinking
* Significant correlation between Critical Thinking scores and college GPA.
* Critical Thinking skills can be learned.
* Significant correlation between Critical Thinking and reading comprehension.
Main Purpose of College Experience
* Achievement of liberal (liberated) education. It's about learning to learn; learning to think for one's self; leads away from naïve acceptance of authority; leads above self-defeating relativism.
* Beyond ambiguous contextualism.
* Culminates in principled, reflective judgment.
All of Us Need Critical Thinking and Thinkers
* Critical Thinking is fundamental, if not essential for, a rational and democratic society.
o Electorate
o Judiciary
o International commerce
* Business and civic leaders maybe more interested in Critical Thinking than even educators.
* Necessary condition for the success of democratic institutions and free market society.
Role of Language in Critical Thinking and Problem Solving
Language is used for three purposes:
* To describe
* To inform
* To persuade
Persuasion is the manner by which we attempt to convince others to "our way of thinking" about a subject therefore:
* Logic
* Fallacious reasoning
* Problem-solving involves persuasion
Language Forms:
* Emotionally charged language-cognitive vs emotional meanings
* Manipulative language: cons, doublespeak and jargon
* Rhetorical devices
o Slanting
o weasel words
o fine print disclaimers
o obfuscation
* Emotional appeal-Advertising

Logic in Critical Thinking
Deduction vs. Induction Logic (Scientific Method)
Deduction
* Draw a conclusion that follows know facts stated in premises.
* Relies on certainty based on connection of premises and conclusion.
* Valid Argument vs. Sound Argument.
* Deductive reasoning can be used when the premises (reasons, facts, evidence, etc.) prove with absolute certainty that the conclusion is true, assuming the premises are true.
Induction
* Derives probable conclusion from observation of diverse facts.
* Learning from experience.
* Argument by analogy.
* Hypothetical Reasoning.
* Inductive Reasoning is required when you cannot ascertain the absolute certainty of the conclusion based on given evidence, but you can establish probability.
Terminology
* Inductive strength: deductive validity, truth of premises.
* Probability: how certain are you.
* Reasoning from diverse facts: reasoning from known facts or assumed known facts.
* Types of Logical Arguments:
o Generalization arguments
o Hypothesis arguments
o Analogical arguments
o Conditional arguments
o Syllogisms
o Venn Diagrams
Five Most Common Fallacies
* Non Sequitur--irrelevant reason-premise no relationship to conclusion.
* Ad hominum-person's character attacked to discredit arguer rather than argument.
* Post hoc ergo propter hoc--generalization--one event which follows was caused by first.
* Slippery slope--black and white--no gray or middle ground-argues against first step since eventually follow through to the last one.
* Appeal to Emotion-emotional appeals rather than logical reasons to persuade.
Logic Problems
* The Premise--establishes the setting of the problem, subjects, how subjects are related, number of subjects (4 to 10).
* The Conditions--rules which impose specific restrictions upon relationship among subjects (2 to 10 conditions).
* The Question--questions about relationship-require deductive analysis.

A Critical Thinking Problem-Solving Model
Problem-Solving Content Issues
* Description of Problem
* Factors: Constructive vs. Limiting
* Ownership
* Scope of Problem
* Consequence of Problem
* Alternative Solutions
* Rank Ordered Solutions
Process Issues in Problem Solving
* Self-awareness of the problem solver
* Motivation of the problem solver
* Decision making involved in selecting solution by solver
* Execution of the solution decided upon
Components of Problem
* Size of problem--costs, risks, losses.
* Sensory Input:
o How's it look?
o How's it sound?
o How's it taste?
o How's its smell?
o How's it feel?
* Personal components of the problem.
* Inside perspective of problem solver of the problem.
What is Needed to Improve Problem Solving Process
* Unconditional acceptance and non-judgmental attitude of fellow solvers.
* Respect for each participant's input.
* Freedom to openly express emotional response to the problem and solutions.
* Defined limits and boundaries on problem solving process.
Ways of Encouraging Creativity in Problem Solving
* Create the desire to be creative--you must want it.
* Expand knowledge and skills of language by reading more to be a creative thinker.
* It takes effort to create--"genius is 1 percent inspiration and 99 perspiration" (Edison).
* Ferment creativity--give it time.
* Evaluate and validate creative ideas.
* Use brainstorming.
* Use starbursting.
Rules for Brainstorming
* Set a time frame to be completed.
* Be clear what problem you are trying to solve.
* All ideas should be heard.
* No idea is too wild to be expressed.
* Quantity is wanted; each idea coming to mind should be expressed.
* Combining ideas for improvement is highly desirable.
* Criticism or negative discussion regarding ideas is absolutely forbidden.
Starbursting
* Focuses on a topic and radiates outward with questions.
* Here anything goes.
* Any questions are legitimate.
* More the questions the better.
* Begin by asking what are the questions.
Problem Solving Through Intimate Engagement
* Engager's have a history of success with similar problems.
* Dismisser's had history of failure with similar problems--captive of the past.
* Rather than dismiss, engage the problem intimately by getting into it.
* Be willing to take the time to deal with the problem.
Engagement Takes:
* Effort to deal with it;
* Time to mull it over;
* Looking at and not averting or looking away.
Rules of Engagement With Problems
* Become sensitive to your own confusion with a problem;
* Do not permit yourself to be confused-do not tolerate confusion;
* Use visual imagery to remember facts;
* Relate the information to people, animals or situations;
* Make your visualization vivid, dynamic, interactive and unusual.
Reality Testing of Possible Solutions to Problem
* Critical Path Analysis;
* Decision Trees;
* Force Field Analysis;
* PMI--Plus, Minus, Interesting;
* SWOT Analysis--Strengths, Weaknesses, Opportunities, Threats.
Critical Path Analysis
* Calculate length of time to complete project;
* List all activities in plan by: start date, duration, if parallel or sequential;
* If dependent on what do they depend;
* Graph it out; plot tasks on graph;;
* Schedule activities;
* Critical path--longest sequence of dependent activities that lead to completion of plan.
Decision Trees
* Start with the decision which needs to be made--draw a box.
* Draw to possible solutions on lines.
* At end of each line, if result is uncertain, draw a circle; if other decision, draw a box.
* From the other decisions draw lines for options which can be taken.
* Calculate decision which has the greatest worth to you and give it a value.
* Estimate probability of each uncertainty.
Force Field Analysis
* List all forces for change in one column.
* List all forces against change in other.
* Assign a score to each force 1 (weak) through 5 (strong).
* Draw diagram showing forces for and against and size of forces.
* Helps weigh importance of factors as to if pursue or not the plan.
PMI--Plus/Minus/Interesting
* Plus Column: all positive points of taking the action.
* Negative Column: all negative effects.
* Interesting Column: extended implications of taking action, whether positive or negative.
* Assign positive or negative scores.
SWOT Analysis
*Strengths: advantages, what you do well
*Weaknesses: could be improved, done badly, should be avoided
*Opportunities: good chances, interesting trends
*Threats: obstacles, competition, are required specifications changing
