title: Inferring category characteristics from sample characteristics: inductive reasoning and social projection.
abstract: Inductive reasoning involves generalization from sample observations to categories. This research examined the conditions under which generalizations go beyond the boundaries of the sampled categories. In Experiment 1, participants sampled colored chips from urns. When categorization was not salient, participants revised their estimates of the probability of a particular color even in urns they had not sampled. As categorization became more salient, generalization became limited to the sampled urn. In Experiment 2 the salience of categorization in social induction was varied. When social categorization was not salient, participants projected their own responses to test items to members of a laboratory group even when they themselves did not belong to this group. When salience increased, projection decreased among nonmembers but not among members. In Experiment 3 these results were replicated in a field setting.
