Religious ritual survives cultural transmission by embedding episodes of intense, life-defining personal experiences in public performances. These pe… - Scott Atran

Another ridge includes social interaction schema. Some of these schema may have aspects that go far back in evolutionary time, such as those involved in detecting predators and seeking protectors, or that govern direct "tit-for-tat" reciprocity (you scratch my back, and I'll scratch yours; if you bite me, then I'll bite you). Other social interaction schema may have elements common to some species of social mammals (e.g., bats, wolves, monkeys, and apes). Examples include certain systematically recurrent forms of delayed reciprocity (you help me now and I'll help you later), indirect reciprocity (I'll help those who help those who help me; the enemies of my enemies are my friends), and greeting displays of submission-domination. Still other social interaction schema appear to be unique to humans, such as making decisions to cooperate on the basis of social signs of reputation rather than on the basis of individual observation and experience, or in offering and obtaining future commitments of an indeterminate nature (when the chips are down, I'll help you, whatever the situation). Only humans, it appears, willingly commit their lives to groups of nonkin.

Mature cognitions of folkpsychology and agency include metarepresentation. This involves the ability to track and build a notion of self over time, to model other minds and worlds, and to represent beliefs about the actual world as being true or false. It also makes lying and deception possible. This threatens any social order. But this same metarepresentational capacity provides the hope and promise of open-ended solutions to problems of moral relativity. It does so by enabling people to conjure up counterintuitive supernatural worlds that cannot be verified or falsified, either logically or empirically. Religious beliefs minimally violate ordinary intuitions about the world, with its inescapable problems, such as death. This frees people to imagine minimally impossible worlds that seem to solve existential dilemmas, including death and deception.

Supernatural agents are critical components of all religions but not of all ideologies. They are, in part, by-products of a naturally selected cognitive mechanism for detecting agents-such as predators, protectors, and prey-and for dealing rapidly and economically with stimulus situations involving people and animals. This innate releasing mechanism is trip-wired to attribute agency to virtually any action that mimics the stimulus conditions of natural agents: faces on clouds, voices in the wind, shadow figures, the intentions of cars or computers, and so on. Among natural agents, predators such as snakes are as likely to be candidates for deification as are protectors, such as parent-figures.
