Heuristics in Decision Making
Representativeness Heuristic
You make a decision based upon how much something represents, or matches up, with characteristics from your schema, or the typical case.
Good
School
Bad School
School
It matches my
‘party school’
schema so I decide
it is bad school.
Representativeness Heuristic in action.
Decide where they are from.

Truth or Lie
I got into a fight in the bathroom and my first grade teacher didn’t break it up.
Availability Heuristic
Operates when we make decisions on how available information is. The faster people can remember an instance of some event the more they expect it to occur.
Availability Heuristic in Action
Ross and Sicoly (1979)
Availability Heuristic
Why does our availability heuristic lead us astray? Whatever increases the ease of retrieving information increases its perceived availability.
How is retrieval facilitated?
Which causes more deaths per 100,000?
Exaggerated Fear
The opposite of having overconfidence is having an exaggerated fear about what may happen. Such fears may be unfounded.
The 9/11 attacks led to a 20% decline in air travel due to fear. 800 more people would die if they drove just half those miles
Which causes more deaths per 100,000?
Which city has the higher crime index?
Answers
Overconfidence
Overconfidence is a tendency to overestimate the accuracy of our beliefs and judgments.
At a stock market, both the seller and the buyer may be confident about their decisions on a stock.
Confirmation Bias
Belief Bias
The tendency of one’s preexisting beliefs to distort logical reasoning by making invalid conclusions.
God is love.
Love is blind
Ray Charles is blind.
Ray Charles is God.

We more easily see the illogic of conclusions that run counter to our beliefs than those that agree with our beliefs.
Belief Perseverance
Belief perseverance is the tendency to cling to our beliefs in the face of contrary evidence.
