This article re-examines societies that have been reported to be free of rape and asserts that the previous claims about societies are questionable. These findings are inconsistent with the hypothesis that rape is a learned behavior and offer support for the view that rape is a cultural universal.

This paper investigates two theories of social stratification: Lenski’s ecological-evolutionary taxonomy which is based on subsistence technology and Service’s taxonomy which is based on social organization. Findings indicate that different components of stratification are better explained by Lenski’s taxonomy, but a global concept of stratification matched better with the Service taxonomy.

Researcher's examine the presence of pubic hair removal (PHR) and retention in a cross-cultural setting, looking to see if such practices exist outside of the West, where it is well documented. Data from societies with PHR or retention from the eHRAF World Cultures sample were analyzed. Results indicate that PHR or retention exists cross-culturally without influence from the West. Commonly practiced for hygiene, women remove or retain pubic hair more often than men, with the main methods for removal being plucking.

Building on previous research concerning murder and suicide, this study investigates 18 forms of aggression and explores how they might be engendered by certain child-training practices. Results show a weak connection between most forms of aggression and child-training practices, but non-literate societies do show a positive correlation between murder and suicide. The author develops a theory positing that experience of social blockage will be related to outwardly-directed aggression, whereas social loss will be related to inwardly-directed aggression.

This paper tests assumptions regarding the inverse relationship between murder and suicide. Analysis suggests that murder and suicide in fact vary together, and they are also positively associated with overall punishment in a society.

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).

This article uses the Standard Cross-Cultural Samples to test the relationship between disease and economic growth among sub-Saharan African societies. The authors suggest that a higher disease prevalence limits social integration and economic development since pre-colonial times. The variable measuring economic growth is the complexity of large or impressive structures. The hypotheses are that 1) pathogen stress is negatively correlated to the presence of complex buildings, and 2) pathogen stress is positively correlated to increased ethnic diversity. The results support both hypotheses, and there are additional results, like 1) the negative correlation between pathogen stress and current income per capita and 2) the negative correlation between the increased ethnic diversity and current income per capita. Overall, this article shows the robust relationship between disease and economic development.

This study relates the type of games present in a society to the level of cultural complexity. Authors use a "game-type combination scale" that categorizes societies as having: 1) games of physical skill only; 2) games of physical skill and games of chance; and 3) games of physical skill, games of chance, and games of strategy. Results show a relationship between the game-type combination scale and indicators of cultural complexity.

This article considers the consequences of modernization. Factor analysis is used to identify four stages of modernization: 1) changes in education, government, and trade; 2) changes in health, technology, and transportation; 3) changes in family, religion, and toilet; and 4) changes in behavior. The authors then consider five trends they expect to be associated with modernization and test whether they develop over the course of the four stages. Results indicate that these 5 trends—increased cultural complexity, female status, pacification, suicide, and social stress—are associated with only the first and fourth stages.
