Document Summary
Categorize something by judging how similar it is to our conception of the typical member of the category. How representative something is does not always map on to how probable it is. Failure to utilize information about frequencies when making decisions. A combination of two will always be less likely than a single event. So even though the combination sounds plausible, its probability is smaller. The base rate for two things will always be lower than for either one of those things. Less likely when differing base-rates have causal significance. If base rate is low because difficult to be in that category. May be more likely to take it into account. On average, people have insight into how different people view their personalities. Conscientiousness, agreeableness, neuroticism, extraversion, and openness (in order of accuracy) Examined how self-schemas influence how we process information.
