The article examines whether cultural groups tend to use supernatural beliefs more to explain natural phenomena or social phenomena. Analysis of ethnographic text from 114 diverse societies reveals that supernatural explanations are more common for natural phenomena, consistent with the theory that humans tend to perceive intent and agency in the natural world. However, supernatural explanations of social phenomena were more prevalent in urbanized societies with greater social complexity and anonymity. The study highlights how people use supernatural beliefs to explain their world and how this varies across small-scale and urbanized communities.

This article tests a broad hypothesis that marital structure is associated with economic type. Results indicate that where women's potential contribution to subsistence is high (as in gathering and agricultural societies), women's contribution is positively associated with polygyny. By contrast, in fishing, hunting, and herding societies, female contribution to subsistence is generally minimal and has a negative association with polygyny.
