Critical Thinking
1. Critical Thinking
Sitting on top of your
shoulders is one of the finest
computers on the earth.
But, like any other muscle in
your body, it needs to be
exercised to work its best.
That exercise is called
THINKING.
I think, therefore I am.
- Rene Descartes

2. What is critical thinking?
Commonly called “problem solving”
Not being content with the first solution to a problem,
but thinking more deeply about it.
Knowing, understanding, analyzing, synthesizing,
applying and evaluating the idea or problem
Looking for what is implied in a question rather than
what is stated
Applying the rules of logic to problem solving
Not letting reason be clouded by emotion
3. Four Aspects of Critical Thinking
Abstract Thinking:
thinking past what your senses tell you
Creative Thinking:
thinking “out of the box,” innovating
Systematic Thinking:
organizing your thoughts into logical steps
Communicative Thinking:
being precise in giving your ideas to others.
4. Critical Thinking: What is involved?
Question: what is being asked?
Purpose: why do I want the answer?
Point of View: where do I stand to look at the
question?
Information: what data do I have?
Concepts: what ideas are involved?
Assumptions: what am I taking for granted?
Inferences: what conclusions am I drawing?
Consequences: what are the implications of my
question?
5. Critical Thinkers
Acknowledge personal limitations.
See problems as exciting challenges.
Have understanding as a goal.
Use evidence to make judgments.
Are interested in others’ ideas.
Are skeptical of extreme views.
Think before acting.
Avoid emotionalism
Keep an open mind
6. Uncritical Thinkers
o Pretend to know more than they do.
o Get annoyed by problems.
o Are impatient.
o Judge on first impressions and
intuition.
o Focus on their own opinions.
o Look only for ideas like their own.
o Are guided by feelings rather than
thoughts.
o Claim that thinking gives them a
headache.
Don’t think
about it,
just sign it!

class requires a lot of have a lot of reading
reading

Generalizations Conclusions
Example: All college My art history course
courses are hard will be hard
9. The IDEAL Method
Identify the problem.
Define the problem.
Explore alternative approaches.
Act on the best strategies.
Look back to evaluate the effects.
Yes, ladies and
gentlemen, it’s
IDEAL!
10. Ask Questions
One quality of a good critical thinker is the ability to ask
on-target questions.
If you don’t usually ask questions, is it because you
Fear embarrassment?
Worry what others will think of you?
Worry that the instructor will think your question is strange?
Worry that others will think you’re showing off?
When you don’t ask questions, you sacrifice your
education.
If you don’t take risks, you won’t get the maximum
benefit in developing your mind.
Yes!
Ask me!
11. There’s No Such Thing as a
Stupid Question (Usually)
There are unwelcome questions.
Don’t ask questions that detract from
the momentum of the class.
Don’t ask questions that focus more
on self-concerns than on the needs of
the class.
Don’t ask questions that demonstrate
you failed to pay attention.
Don’t ask silly questions.
Can I draw
you a
conclusion?
Well, can I?
12. Offer Criticism
You will most likely be asked to judge or
evaluate issues in college.
First decide whether you like what you
are being asked to judge.
Consider both positive and negative
attributes.
Use examples to support your judgment.
Don’t be intimidated by this kind of
assignment; your instructors want you to
develop your critical thinking skills.
13. Make the Right Inferences
You are constantly making inferences.
Inferences are interpretations that you derive
from processing cues in a situation.
A plausible inference is a judgment that is
logical, and possibly accurate.
Sometimes inferences become assumptions—
something we believe to be true and act on as
though it were.
Inferences can be tricky. It is easy to be wrong
and you may operate on faulty assumptions until
you are informed otherwise.
14. Four Common Decision Making
Problems
Snap decisions
Don’t jump to conclusions!
Narrow thinking
Broaden your vistas!
Sprawling thinking
Don’t beat around the bush!
Fuzzy thinking
Keep it sharp! Keep it relevant!
15. What is a Claim?
A claim is a statement which can be either true or false, but not
both.
A claim is an assertion you want to have accepted as a fact and
not be disputed.
When evaluating a claim, you have three choices:
accept the claim
reject the claim
suspend judgment until you have more information
What is an Argument?
An argument is a set of claims.
Arguments begin with premises and lead to a conclusion
A good argument is one in which the premises lead
logically to a strong or valid conclusion.
I’m
stakin’
a claim!
16. Form Strong Arguments
Be sure the conclusion follows logically from the
premises.
Leave out faulty or dubious premises.
Use precise language to pinpoint your claim.
Avoid making claims you can’t prove.
This is a perfectly logical
argument (called a syllogism.)
It only has one small problem:
NASA hasn’t found any green
men on Mars. Oh, well…
17. Know Your Own Biases
Everyone has strong preferences and prejudices
that may prevent us from evaluating arguments
fairly.
Acknowledging these can increase the likelihood
of coming up with more effective arguments.
Good reasoners guard against their own “soft
spots” to increase their objectivity.
Be honest with yourself: “Am I opinionated?
18. Refine Your Reasoning
Be willing to argue
Use deductive reasoning
Check your assumptions
Know your own biases
Observe carefully
Stay positive and persistent
Show concern for accuracy
Take time before concluding

They actively pursue experiences that are
aesthetically pleasing.
They enjoy taking a unique approach to
things.
They love the process of creating.
They are flexible and like to play with
problems.
They take risks and learn from their
mistakes.
They strive to evaluate their work fairly.
They thrive when they think of assignment
guidelines as a launching point for their
imagination.
20. Nurture Your Own Creativity
Don’t accept other people’s blueprints.
Be vigilant about what others can’t see.
Differentiate the good from the bad.
Take the plunge before you’re an expert.
Concentrate on the big picture.
Take sensible risks.
Motivate yourself from inside.
Shape environments that will support your
creativity.
Actively pursue your creative life.
21. Critical Thinking:
A Skill to Carry You Through Life
Professors and future employers value your ability
to perform these critical thinking skills:
Manage and interpret information
Examine exciting ideas and develop new ones
Pose logical and cogent arguments
Recognize reliable evidence
Be proactive rather than reactive
Think things through in depth. Always
be
reasonable
22. Why College Encourages Critical Thinking
Remember:
Thinkers are generally “movers and shakers.”
Sometimes how you solve a problem is as important as
the solution.
Open ended questions of “Why?”, “How?” or “What If?”
have no simple, clear-cut answers.
There are many valid points of view!
The greatest gift a college can give you is an open mind.
23. Exercise 5.2 in textbook (page 97)

chosen field of study.
Prepare a short paper as described in your
syllabus.
Be prepared to discuss your findings in class
on Monday, Sept. 24th.
