Document Summary
Comparison group: enables us to compare what would happen both with and without the thing we are interested in. Confederate: an actor playing a specific role for the experimenter. Probabilistic: the findings are not expected to explain all cases all of the time, but instead to explain a certain proportion of the possible cases. Cognitive biases: thinking it makes sense or is a good story, draws on something familiar (freud and steam). Example of cognitive bias: availability heuristic: things that pop up easily in our mind tend to guide our thinking. Present/present bias: we easily notice what is present. Motivational biases: cherry picking information because we don"t want to challenge our current beliefs. Confirmatory hypothesis testing: asking biased questions to get the result you want. We are biased about being biased: the bias blind spot: the belief that we are unlikely to fall pretty to the cognitive biases previously described. Think about where the authority got their information and how.
