Abstract:

Religious ritual is omnipresent in human societies, but unique to our species. Functional explanations of the phenomenon often ignore the most puzzling parts of ritual: its origins. Why and how does a population adopt a new ritual given the costs associated with the activity and its inefficacy? A new, 4 year old, apparition of Jesus that has spawned a yearly festival in the Peruvian Altiplano provides a rare opportunity to test competing hypotheses about the origins and spread of religious ritual. Using data from over 600 interviews with residents in 4 districts in the region, we will examine who adopts new religious practices, and the mechanisms that lead to its persistence and spread.
