This study uses Bayesian phylogenetic regression modelling across 131 largely non-industrial societies to test how variation of punishment is impacted by social, economic, and political organization. The authors focus on the presence of norm violations and types of punishments, and explores their relationships. The norm violations include adultery, rape, religious violations, food violations, and war cowardice. While the types of punishment are reputational, material, physical, or education. This study suggests a hypothesis for each type of punishment in relation to socioecological variables.

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 study investigates previous findings that indicate precolonial centralization was beneficial for development in Africa. Using new survey data from public primary schools, the author shows that the failure of leaders of centralized regions to comply with federal regimes was punished with underinvestment in public infrastructure services, hindering development and limiting access to these services in recent populations. The author proposes that the extent to which precolonial centralization was beneficial for development in Africa is mediated by compliance of the local governing bodies with federal regimes.
