Document Summary
Judgment- deciding on likelihood of events using information available: base rates info is often misused, base rate info- relative frequency of an event in a population, heuristics-rules of thumb. Representative heuristic: object belongs to category because it is representative of that category. Conjunction fallacy: mistaken assumption that 2 events together is more likely than one on its own. Availability heuristic:frequency of a given event is estimated based on the readiness at which it came to mind. Availability by recall: how many can you remebr that happening to. Fluency: how easily one can think of instances of that happeninh. Recognition heuristic: selecting one of the two objects that is recognized. Natural frequency hypothesis- easy to work out frequencies of different kinds of events but difficulties with fractions and percent"s. System 1: intuitive, automatic, and immediate, most heuristics are produced by this system, stereotypes, unconscious.
