This article investigates material and social predictors of belief in a high god. The author introduces a new variable, the inertness of subsistence raw materials, to be compared with Swanson’s (1960) variable representing the number of sovereign groups. Both variables were significant predictors of belief in high gods. Relevant theory is discussed.

The expressed purpose of the present publication is to provide a typology of institutionalized dissociational states on a world-wide basis, using biological, situational, and cultural parameters. The study is comprised of field work, literature review, ethnographic research, and cross-cultural statistical analysis. The researchers use these findings to aid in the construction of cross-cultural theory, and to provide a platform for further work on dissociational states to continue.

This study examines the relationship between personality traits and subsistence type in mixed farming and pastoralists societies. Findings suggest that differences in child socialization do not significantly predict personality differences in mixed farming and pastoralist societies as much as one would expect. Adult experiences should be considered as better predictors of personality traits.

This article investigates a cultural patterning of altered states of consciousness. The authors use an ordinal variable for a society's trance type; its four levels are 1) trance, 2) trance and possession trance, 3) possession trance, and 4) neither type. Results suggest that trance type is associated with measures of societal complexity and subsistence economy. Regional differences and the effects of diffusion are also examined.

This article tests several hypotheses related to the presence or absence of polygyny. Results suggest a negative relationship between polygyny and male provisioning, and positive relationships between polygyny and warfare, interpersonal aggression, and pathogen stress.

This study presents a sociological theory of marriage type based on socioeconomic organization. Results suggest that intensive agriculture, more stratification, greater political integration, a fixed settlement pattern, a larger population, and greater labor specialization tended to be correlates of monogamy.

This study tests the hypotheses that games of strategy will be more prevalent in societies where political power is based on a "network strategy" and that network societies place more value on the enculturation of obedience in children. Both hypotheses are supported.

Using paternal investment theory, the authors examine the relationship between paternal confidence and paternal investment in humans.

The goal of the paper is to demonstrate how international slave trade spread the institution of slavery throughout Africa, resulting in long-term effects of the continent’s income and political centralization. The author first estimated the travel time to slave ports from each society in the Ethnographic Atlas to determine predicting factors for the adoption of slave trade in African societies. The author reported that societies with high exposure to slave capture in the past were more likely to have the custom of slavery and the custom of polygyny. The author further suggested that slavery institutions emerged in West Africa through local, politically centralized aristocratic systems while emerging in East Africa through the preservation of wealth within the nuclear family over generations.

This study examines socio-economic predictors of political complexity. Findings suggest that class stratification is the most significant predictor of political complexity.
