Judgment
The ability to reason
- efficient and accurate
- gain efficiency at the cost of accuracy
Heuristic
A mental shortcut to understand things
Types of judgment heuristics
- Attribute substitution
- Availability heuristic
- Representative heuristic
Attribute substitution
- Relies on easily accessed information rather than facts of the individual case
- works well when the easily accessible info relates to the desired side of the information or debate
Availability heuristic
- Judges frequency of something at the ease at which something can come to mind
- we assume airplanes are more dangerous than cars bc of news
- “probability”?
- “availability” based on frequency of situation or circumstance comes to mind
Representative heuristic
- generalizing one person to be like or have traits like a person in their group or category overall
- online video of cop shooting, now all cops are bad
- prototype
Induction
Broad Judgements are made from specific observations and cases
Specific to general
Covariation
A relationship between two variables where the presence of one can be predicted by the other
- ex.) Does college lead to a higher paying job?
Illusion covariation
False covariance
- astrology
Confirmation bias
We ignore disconfirming data
- similar to overregularzation by schemata
Base rate information
Information about the broad likelihood of an event
- can cause covariantion estimates to be incorrect is a neglect of base rate information
- this is why control group is needed
Dual processing model
System 1 & 2
System 1
Fast, automatic thinking, uses heuristics
System 2
Slower thinking, effortful, and more likely to be corrected
Deduction
Starts with general premise and asks what follows in more specific terms
Selective memory
Memory for disconfirmong evidence is often remembered selectively
Belief preserverance
We notice evidence against our belief but ignore it so as not to be swayed from the original belief/viewpoint.
- failure in logic
3 most common errors Iogic
- Belief bias
- Affirming consequence
- Denying antecedents
Belief bias
Tendency to endorse conclusions that only fit with what you believe
Utility maximization
Option w greatest expected value
Reason-based choice
Ppl make a decision only when they detect what they belive to be a persuasive reason for making that choice
Affective forcasting
Emotions play a role on decisions
