Document Summary
Judgment: deciding the likelihood of events; assessed by accuracy (e. g. , how likely is it that your friend will drive you to the store?) Decision making: selecting from various choices; assessed by their consequences (e. g. , what should i take as my major?) Heuristics: mental shortcuts used in judgment and decision making (easy to use, minimal cognitive effort, not always accurate, leads to characteristic errors, consistent across individuals) Errors help us understand how heuristics are being used. Quick easy answers that are usually good enough. Help us understand how decision making and judgment processes work. Representativeness heuristic: the bias towards thinking that something is more likely to belong to a specific category if it appears representative of it. Prototypical examples are believed to be more likely and distort our estimates of probability. E. g. , a random number generator; presents the number 1 (1 doesn"t seem like a random number) but the likelihood of 1 being presented is equal to any other number.
