Document Summary
Seeks out evidence that could falsify a hypothesis. Requires effort and caution to reach correct conclusions. Does not act to alter the observed phenomenon. Attends to evidence that violates own hypothesis. Acts in way that alter the observed phenomenon. Is biased to see patterns matching own expectation. Easy, intuitive judgments our minds preform naturally/automatically without deliberation (gut feelings, mental shortcuts) (eg. liking/disliking similarity, perceptual/cognitive fluency) Other judgments are not automated and demand more extensive attention and resource-dependent deliberation (eg. probability, scope/importance) Attribute substitution: when judgments tax information processing capacities, people often substitute an answer to a related judgment. Our reliance on the feelings that we experience as we think about a topic to judge importance/risk/satisfaction. Potential problems with feelings (eg. contaminated by irrelevant experiences) Asked participants on rainy days vs. sunny days about life satisfaction. Representativeness heuristic tendency to classify something according to how similar it seems to a typical case. Problem: leads to conjunction fallacy, base rate neglect.
