Document Summary

March 6th implicit memory and real-world judgement. People tend to underestimate populations of large, obscure countries. People tend to overestimate populations of small, well-known countries. Possible explanation for availability bias: domain-specific knowledge and fluency-based intuitions can influence real- world estimation for populations estimation: people use fluency/familiarity/availability to gauge relative population size, assumption: better known countries have larger population than less well-known countries. Terminology: tversky & kahneman (1973) identified the (cid:862)availability heuristic(cid:863) when ease-of-retrieval used to estimate frequency or probability of events. Generalization: ease-of-retrieval fluency, familiarity, a(cid:448)aila(cid:271)ilit(cid:455)(cid:863) used i(cid:374) situatio(cid:374)s i(cid:374) (cid:449)hi(cid:272)h flue(cid:374)(cid:272)(cid:455) is fou(cid:374)d to affect judgment and decision making. The logic of the availability (fluency, familiarity: assume: propx correlates w/ memory, goal: propx for itemi, mechanism, assesses availability of info for itemi, use assessment as index of propx for itemi. Implicit memory and real estimation brown & siegler. Background: availability might be a good cue for estimating population.
