Abstract

Convergent developments across social scientific disciplines provide evidence that ritual is a psychologically prepared, culturally inherited, behavioral trademark of our species. We draw on evidence from the anthropological and evolutionary-science literatures to offer a psychological account of the social functions of ritual for group behavior. Solving the adaptive problems associated with group living requires psychological mechanisms for identifying group members, ensuring their commitment to the group, facilitating cooperation with coalitions, and maintaining group cohesion. The intersection of these lines of inquiry yields new avenues for theory and research on the evolution and ontogeny of social group cognition.
