Document Summary

Reasoning: deductive structure helps determining truth. If argument is valid you can assume conclusion is true: requires executive function, understanding rules of logic, doesn"t come naturally, content can interfere w/ability to understand. Inductive structure cannot determine truth content is important your knowledge about something will help generalizes to different concepts. Inductive reasoning probabilistic reasoning how ppl understand problem, how they make errors base rates most of us overestimate likelihood of low probability events. 5 chance (1 desired outcome, 2 possible outcomes) Multiple outcomes probability of getting 2 heads in a row: and rule multiply sequential/serial probabilities are multiplied probability of getting 2 heads or 2 tails: or rule add cumulative probabilities are added together. And/or rules assume independence: one event doesn"t influence next outcome, humans don"t like to assume independence like to assume causality, figure out what causes something else.
