Extreme Rituals Promote Prosociality
Psychological ScienceShort Report Extreme rituals entail excessive costs without apparentbenefits, which raises an evolutionary cost problem(Irons, 2001). It is argued that such intense rituals enhancesocial cohesion and promote cooperative behaviors(Atran & Henrich, 2010; Durkheim, 1912). However,direct evidence for the relation between ritual intensityand prosociality is lacking. Using economic measuresof generosity and contextually relevant indicators ofgroup identity in a real-world setting, we evaluated pro-social effects from naturally occurring rituals that variedin severity.
