Stereotypes
We present a model of stereotypes in which a decision maker assessing a group recalls only that group?s most representative or distinctive types. Stereotypes highlight differences between groups, and are especially inaccurate (consisting of unlikely, extreme types) when groups are similar. Stereotypical thinking implies overreaction to information that generates or confirms a stereotype, and underreaction to information that contradicts it. Stereotypes can change if new information changes the group?s most distinctive trait. We present experimental evidence on the role of representativeness in shaping subjects? mental representation of groups.
