This study used data from the Afrobarometer Survey to compare the cultures of 85 ethnolinguistic groups from 25 African countries on markers of cultural modernization and emancipation, such as attitudes towards gender equality, xenophobia, and the role of religion in society. The study found that nearly all of the ethnolinguistic groups studied within a country clustered together in terms of their attitudes towards cultural modernization. The study also found that the variation between nations was often greater than the variation between ethnolinguistic groups, and that the cultural differences between ethnolinguistic groups within a nation were highly correlated with economic indicators such as GDP per person, employment in agriculture and the service sector, and phone subscriptions per person. The study suggests that economic development and modernization lead to cultural homogenization within a nation and a decreasing relevance of ethnolinguistic culture.

This study empirically tests Durkheim’s theories of punishment in a sample of preindustrial societies. Analysis shows little support for five hypotheses derived from Durkheim’s theories. Findings indicate that in preindustrial societies, the intensity of punishment is associated with political integration, there are fewer collective definitions of crime, there is a higher likelihood of using material sanctions; additionally, slavery is likely to be an institutionalized means of punishment in societies with harsher sanctions.

This article examines the origin of money. Anthropologists’ and economists’ theories are discussed and data supports a broad hypothesis that the existence of money is associated with level of economic development. The author further examines the emergence of internal, external, commercial and noncommercial moneys at high and low levels of economic development.

This article investigates potential relationships between food deprivation, parental rejection, and personality development. Findings indicate that a series of adult personality characteristics (e.g. self evaluation and emotional responsiveness) are better predicted by parental rejection than by nutritional variables.

The researchers introduce the Pulotu database to readers, reviewing its function and role in future research. Researchers demonstrate the utility of the database by testing for headhunting cross-culturally. Findings include the presence of headhunting practices across proto-Austronesian cultures.

The purpose of this book is to introduce a conceptual and methodological perspective called the "universalist approach," and to use this approach in exploring the pancultural antecedents and affects of parental acceptance-rejection of children,

In this study, the authors inspect the relationship between religion, morality, and cooperation by examining the extent to which people associate their deities with moral concern. Using data from 2,228 individuals in 15 different field sites, they find that on average, people tend to ascribe at least some moral concern to their deities, and this effect is stable even after controlling for the influence of explicitly moralistic deities that these societies also worship. The authors also find that ratings of moral concern are not necessarily very high, even for deities that are typically considered to be moralistic, and that there is individual-level variation in the degree of moral concern attributed to deities. In addition, there is an individual-level correlation between how morally interested two selected deities are conceived to be and that being male or more educated decreases the likelihood of associating deities with moral concern. These findings challenge the longstanding belief that belief in moralistic deities is unique to certain societies or religions and instead suggest that the association between deities and moral concern is more widespread and variable, and suggest that the moral character of gods may be tied to cooperation within societies.

This study tests possible explanations for sexual dimorphism in human post-reproductive life-spans. The author focuses on explanations involving male paternal investment and finds that men in agricultural societies are more likely to invest in their offspring than men in hunter-gatherer societies.

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.

Humans, just like other mammals, tend to allow greater sexual freedom for men rather than women. Furthermore, females are burdened with the majority of parenting. Do parenting costs limit sexual unrestrictedness to a different degree for males and females? The authors find that across 48 cultures, as women’s parenting costs decreased through improved physiological and economic conditions, women’s sexual unrestrictedness increased.
