Cognitive-evolutionary approaches to normative psychology are likewise interdisciplinary, and aspire to accommodate empirical research done on norms by anthropologists, sociologists, behavioral economists, and developmental, comparative, and other kinds of psychologists. This section provides a sampling of the sorts of findings that have been marshalled to illuminate interesting aspects of norm-guided behavior and support different claims about normative cognition.
