Document Summary

A. 1: limits of intuition: more often than not intuition is misleading, hindsight bias, overconfidence, & perceiving order in random events leads to overestimation of intuition. 7 billion people can fit in one sugar cube (because atoms are made mostly of empty space) A. 2: limits of common sense: develop common sense as a result of us learning before/ our experiences. Limited to hindsight bias (opposite findings can seem like common sense) (cid:862)i-knew-it-all-alo(cid:374)g(cid:863) phe(cid:374)o(cid:373)e(cid:374)o(cid:374: once we have learned all facts/conclusions about something, it is our tende(cid:374)(cid:272)y to (cid:271)elie(cid:448)e (cid:449)e (cid:272)ould"(cid:448)e easily predicted it e. g. If we do not know the facts or conclusions, we cannot predict. Cognitive bias: our tendency to overestimate the accuracy of our skills/performance/opinions, confident > accuracy + skill: therefore we need science. Definition: when we perceive a relationship between variables but there is no relationship. Effects: influences and affects cognitive processes, behaviours, emotions (memory bias) A. 5 perceiving order in random events: we are uncomfortable with known random events.
