Representativeness Revisited: Attribute Substitution in Intuitive Judgement

The first section introduces a distinction between two families of cognitive operations, called System 1 and System 2. The second section presents an attribute-substitution model of heuristic judgement, which elaborates and extends earlier treatments of the topic. The third section introduces a research design for studying attribute substituion. The fourth section discusses the controversy over the representativeness heuristic. The last section situates representativeness within a broad family of prototype heuristics, in which properties of a prototypical exemplar dominate global judgements concerning an entire set.
