title: Credibility, credulity, and redistribution.
abstract: After raising some doubts for cultural group selection as an explanation of prosocial religiosity, we propose an alternative that views it as a "greenbeard effect." We combine the dynamic constraints on the evolution of greenbeard effects with Iannaccone's (1994) account of strict sects. Our model shows that certain social conditions may foster credulity and prosociality.
