Document Summary
Pluralistic ignorance: not knowing or having mistakes about others" thinking. When we have an idea about something (ex: we want to stop something that"s uncomfortable, but you feel that other people won"t agree with you so you don"t do anything) Others thoughts and beliefs (typically positive) are different from our own. Illusory correlation: seeing patterns when none are there. Small sample bias law of small numbers. Smaller test size is more likely to not be representative/statistically a small sample will have more variability. More likely to have extreme cases (good or bad) Heuristics: shortcuts in thinking that lead to biases. Work has been very impactful in the world of economics: kahneman is one of two psychologists who have received the nobel prize. Representative heuristics: results in quick judgments of people, easy to classify individuals by their looks based on prior beliefs, this strategy ignores base rate: It ignores the likelihood that a person is in a given category.
