This article explores the following questions: What environmental and cultural factors might explain variation in prejudice across cultures? Do these factors explain the intention to vote for nationalist politicians? The authors perform seven studies, focusing on the link between cultural tightness and the rise of prejudice in cultures. They theorize that cultural tightness is positively correlated with the rise of prejudice against people perceived as disrupting the social order. From this theory, they suggest three hypotheses: 1) cultural variation in tightness is related to cultural variation in prejudice, 2) cultural tightness is related to the support for nationalist politicians, and 3) cultural tightness is a link between ecological threats and prejudice. The results support these hypotheses, offering a cultural evolutionary perspective on prejudice.

This article tests three types of theories of gender inequality in preindustrial societies. Bivariate and multivariate analyses suggest little support for militarist theories, moderate support for Marxian theories, and strong support for non-Marxian theories.

Researchers looked at the meaning of various emotion concepts, 'emotion semantics' in an attempt to determine the patterns and processes behind meaning cross-culturally. They used maps of colexification patterns (where semantically related concepts are named with the same word), adjusted Rand indices (ARIs) which indicated the similarities of two community's network structures, and various psychophysiological dimensions to test relationships and patterns of variability /structure in emotion semantics. These methods shed light on the underlying mechanisms behind emotions, both their words and their meanings in languages across the world. Their findings show substantial difference in language families and relationships between geographic proximity of language families and subsequent variation in emotion colexification tied to an evolutionary relationship, while also finding cultural universals in emotion colexification networks with languages primarily differentiating emotions on the basis of valence and activation.

This article builds on previous cross-country and cross-state research into Tightness-Looseness (TL) theory, which proposes relationships between the incidence of ecological threat and cultural tightness, as well as tightness’ downstream effects on belief in a moralizing high god, inter-group contact and authoritarian leadership. To evaluate the generalizability of TL theory beyond complex cultures, the authors test these relationships among 86 nonindustrial societies from the ethnographic record. A structural equation model is presented of the results for nonindustrial societies; it is generally in accord with previous findings from more complex societies. Because the nonindustrial sample is more variable, they also look at relationships between societal complexity and kinship heterogeneity, aspects that vary in nonindustrial societies.

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 is a reexamination of Bacon's (1965) previous cross-cultural study regarding drinking. The current study supports the dependency-conflict hypothesis that frequency of drunkenness is related to dependency needs in childhood and adulthood.

Female aggression, reasons and targets of that aggression are described using a cross-cultural sample. It is suggested that female aggression is often a means of competing for men or subsistence products, but it also may be a means of defense.

Causal factors to the development of crime are examined. Frequency of theft and personal crime are tested against these causal factors in a search for correlations.

Textor's (1967) A Cross-Cultural Summary is used to test a variety of Sauer's (1952) hypotheses concerning the sequence of agricultural developments. Tests are primarily focused on subsistence variables.

A study of the relationship between older women and their young female kin. Relationships between women's relationships with their mother-in-laws and subsistence contribution, residence, descent, and food preparation are examined. Findings offer significant support for patterns in the relationship between older women and younger female kin.
