Overview of Critical Thinking
Content:
What is Thinking Process?
- Sensation- Eyes, Ears, Nose, Tongue, Skin 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 (eyes, ears, hands, fingers & skin, nose, tongue)
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:
- 1 Birth to 2 years old - no thinking structures (called schemas)
and starts to develop such schemas through exploration of senses and
experimentation with environment
- 2. Preoperational Stage: 2-7 years old - develop language skills
and more sophisticated cognitive structures but still is prelogical.
- Not capable of conservation-ability to understand that substance does
not change although it changes shape or form
- Incapable of decentering-ability to see things from another
perspective
- 3. Concrete Operational Stage: 7 years to Adolescence - begin to
grasp conservation and decentering. Begins to question life. Solves problems
but haphazardly.
- 4. 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:
- 5. 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
- Do these assumptions make sense?
- Do these assumptions fit reality as we understand and live it?
- 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. (rather: it is 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: http://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
For more information on this site about perceptions see:
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 & shut out alternatives
For more information on this site about assumptions see:
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
- Explain
- Language denotes and connotes
- Metaphors
For more information on this site about language see:
Metaphors
Metaphors are
powerful language tools which 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:
Argument
- Claim, used to persuade that something is (or not) true or should (or
not) be done
- Contains three basic elements
- Issue
- One or more reasons (premises)
- One or more conclusions
- Can be valid or invalid based on structure
- Only premises & 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 & editorials
Logic
Two methods of reasoning
Deductive
- Facts, certainty, syllogisms, validity, truth of premises
sound arguments & conclusions
Inductive
- Diverse facts, probability, generalizations, hypotheses, analogies
inductive strength
Logic problems Problem Solving
- Logic problems like any problem
- Techniques:
- Understand the problem. Read
& heed
- ID unknowns & knowns
- Relationships between these (visual aids)
- Generate strategy from step above
- Apply and solve. Repeat if
necessary

Six Cognitive Skills
- Interpretation
- Analysis
- Evaluation
- Inference
- Explanation
- Self-regulation
Affective Dispositions “a critical spirit”
Interpretation
- Comprehend & express meaning or significance of wide variety of
experiences, situations, data, events, judgments, conventions, beliefs,
rules, procedures, or criteria.
Analysis
- Identify the intended & 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 &
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 educed, 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
- Issues
- The best way we know to get to the truth.
- Experts conclude: Critical Thinking is pervasive, purposeful human
phenomenon
- Ideal critical thinker characterized also by how he or she 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 & 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 & applying criteria
- Care in focusing attention on the concern at hand
- Persistence through difficulties
- Precision to the degree permitted by subject & circumstances

Value of Critical Thinking
Why is Critical Thinking of Value?
- You can answer—why of value to you?
- What’s value of cognitive skills?
- What’s value of the critical spirit?
- Would these mean more success at what you do?
- Would it mean better grades for students?
- Grades – Yes!
- 1,100 college students
- Significant correlation between Critical Thinking scores &
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
- Electorate
- Judiciary
- 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 all involve persuasion
Language Forms:
- Emotionally charged language-cognitive vs emotional meanings
- Manipulative language: cons, doublespeak, jargon & bureaucrats
- Rhetorical devices
- Slanting
- weasel words
- fine print disclaimers
- 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 & 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,
sound
- Probability: certainty
- Reasoning from diverse facts: reasoning from known facts or assumed
known facts
- Types of Logical Arguments:
- Generalization arguments
- Hypothesis arguments
- Analogical arguments
- Conditional arguments
- Syllogisms
- Venn Diagrams
Valid vs Invalid Arguments
Hypothetical syllogisms (conditional arguments) can have two valid and two
invalid structures
| Structures of Syllogisms |
Antecedent |
Consequent |
| valid |
Affirming (modus poens) |
Denying (modus tellens) |
| invalid |
Denying |
Affirming |
5 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 1st
- Slippery slope-black & white-no gray or middle ground-argues
against 1st 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 (4-10)
- The Conditions- rules which impose specific restrictions upon
relationship among subjects (2-10 conditions)
- The Question-questions about relationship-require deductive
analysis

- 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
- Visceral Components of the Problem
- Size of Problem - costs, risks, losses
- Sensory Input
- How’s it look?
- How’s it sound?
- How’s it taste?
- How’s its smell?
- How’s it feel?
- Personal Components of the Problem
- Inside perspective of problem solver of the problem
If on Team other members as problem solvers & their perspective
Low self-esteem of problem solver is the hidden component in problem solving
which must be addressed to insure productive solutions
What is Needed to Improve Problem Solving Process
- Unconditional acceptance & non-judgmental attitude of fellow solvers
- Respect for each participant’s input
- Freedom to openly express emotional response to the problem &
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 & Skills of language by reading more to be creative
thinker
- It takes effort to create-genius is 1% inspiration & 99%
perspiration-Edison
- Ferment creativity-give it time
- Evaluate and validate creative ideas
- Use Brainstorming
- Use Starbursting
- 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.
- 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
- 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, & 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
- Start with the decision which needs to be made draw a box
- Draw to right possible solutions on lines
- At End of each line if result is uncertain draw circle if
other decision draw box
- From the other decisions draw lines for options which can be taken
- Calculate decision which has 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)-5(strong)
- Draw diagram showing forces for & 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
-
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
