Resource Stress Predicts Changes in Religious Belief and Increases in Sharing Behavior.

We examine and test alternative models for explaining the relationships between resource stress, beliefs that gods and spirits influence weather (to help or harm food supply or punish for norm violations), and customary beyond-household sharing behavior. Our model, the resource stress model, suggests that resource stress affects both sharing as well as conceptions of gods' involvement with weather, but these supernatural beliefs play no role in explaining sharing. An alternative model, the moralizing high god model, suggests that the relationship between resource stress and sharing is at least partially mediated by religious beliefs in moralizing high gods. We compared the models using a worldwide sample of 96 cultures from the Standard Cross-Cultural Sample (SCCS), newly coded data on supernatural involvement with weather, and previously coded data on food and labor sharing. We conducted three types of analysis: multilevel and society-level regressions, and mediational path modeling using Monte Carlo simulations. Resource stress shows a robust effect on beliefs that high gods are associated with weather (and the more specific beliefs that high gods help or hurt the food supply with weather), that superior gods help the food supply through weather, and that minor spirits hurt the food supply through weather. Resource stress also predicts greater belief in moralizing high gods. However, no form of high god belief that we test significantly predicts more sharing. Mediational models suggest the religious beliefs do not significantly explain why resource stress is associated with food and labor sharing. Our findings generally accord with the view that resource stress changes religious belief and has a direct effect on sharing behavior, unmediated by high god beliefs.
