Thinking & Language
Obstacles to problem solving
Confirmation bias



Looking for and accepting evidence that
supports our preconceived ideas.
“Don’t bother me with the facts,I have
made up my mind.”
Makes it difficult to consider
contradictory information.
Fixation

Inability to see a problem from a new
viewpoint.
Mental set



We see what we expect
What worked in the past
Makes it difficult to see a problem
differently.
Functional fixedness


Seeing things only one way
Makes it difficult to see different uses for
things.
Heuristics


Mental shortcuts
Often helpful, but can cause problems.
Heuristics

Representativeness



This person is representative of (similar to) this
group.
Therefore, he has these characteristics
Availability



An available (memorable) clear powerful memory
is more powerful than a statistical reality.
We over feel and under think
E.g. Deaths from 9/11 VS smoking
Heuristics

Overconfidence



We tend to overestimate our own abilities
and underestimate others.
Stock purchases - E.g. E-trade, or Charles
Schwab online trades
Reality rarely reduces their overconfidence
in the next situation.
Heuristics

Belief perseverance

When given mixed evidence, two opposing parties
will actually increase their disagreement.




We believe only what supports our preexisting beliefs
Prejudice persists because once formed, opposing
evidence is rejected.
What you can do: Consider the opposite (or argue
the other‘s point of view).
E.g. Family therapy
Framing

We judge things differently based on how the
information is presented.






10% die VS. 90% survival rate of an operation
“Aid to the needy” vs.”Welfare”
“Cloning” vs. “Nuclear cell transfer”
“Opt in” vs. “Opt out”
Divorce = Sin vs. independence
You can change people’s perception of a
situation by reframing it.
Fear

We fear:

1. What evolution and our ancestral history
prepared us to fear.


2. What we can not control


E.g. flying vs. smoking.
4. What is most memorable


E.g. Tandem jump VS static line
3. What is immediate VS. long term


E.g. heights and spiders
E.g. 9/11 vs. traffic deaths
Result: Check your fears against the facts

We fear too little events that claim lives undramatically.
Thought problems to avoid

1. Hindsight bias


“I knew it all along.” - After you know the result.
2. Illusory correlation

Thinking 2 things are related when they are not.


E.g. adoption and pregnancy
3. Memory Construction

Misinformation can create false memories
Thought problems to avoid

4. Self serving bias

Inflated self assessments

E.g. If I do well I take the credit


If I do poorly, others are to blame
5. Fundamental attribution error


Attributing behavior of others to their
disposition (personality) and ignoring the
environment.
E.g. The homeless person is just lazy
