This study presents a phylogenetic approach to the work of Hartung (1982) on the relationship between inheritance and marriage patterns. Results indicate that polygyny is associated with male-biased inheritance.

The complex set of beliefs and practices in which the cult of the guardian spirit consisted is examined.

This article contests Underhill’s (1975) claim that monotheism is associated more strongly with subsistence than political organization in preindustrial societies. The author asserts that when political organization is held constant, there is no relationship between subsistence strategy and monotheism. Number of sovereign groups is found to be a good predictor of monotheism.

This study examines correlates of trance and possession in pre-industrial societies. Results suggest that the presence of trance/possession is associated with subsistence, number of jurisdictional levels, and community decision-making.

This paper introduces a typology that “classifies collectivities according to fundamentals of their organization for making decisions and taking action” (607). Analysis focuses on the constitutional system and its relationship with need achievement and narcissism. Hypotheses are supported.

This book investigates the origins of supernatural and religious beliefs. The author tests associations between various types of beliefs (e.g. witchcraft, monotheism) and various societal characteristics (e.g. mobility, class stratification). Many hypotheses are supported. Theoretical discussion is included, and the author posits that “the belief in a particular kind of spirit springs from experiences with a type of persisting sovereign group whose area of jurisdiction corresponds to that attributed to the spirit” (175).

This article retests several hypotheses from Swanson’s (1960) study on the origins of religious belief. The author finds support for an association between high gods and large communities, multiple levels of political hierarchy, and social differentiation. No support is found for Swanson’s other hypotheses concerning polytheism, ancestral spirits, reincarnation, the soul, witchcraft, and morality and their relations to social, political, and economic variables.

Using a new measure called "territorial fractionalization" to indicate the extent to which traditional societies are split across current states, the authors of this study propose that fragmentation of ethnic groups and ethnonationalism is key to understanding civil conflict. They find that higher measures of territorial fractionalization significantly predict a higher risk of civil conflict, and that greater increases in territorial fractionalization also predict greater risk of civil conflict. These results hold for a global sample of data from 1945 to 2017, as well as in European and African subsamples dating back to 1886.

This study explores predictors of variation in two dimensions of marital residence patterns among hunter-gatherers: 1) the tendency toward patrilocality versus matrilocality and 2) the tendency toward unilocality versus bilocality.

The present research investigates food sharing and labor sharing practices of 98 nonindustrial societies. The aims are to: 1) document the frequency and scope of sharing, and 2) test the theory that greater sharing is adaptive in societies subject to more resource stress (including natural hazards).
