The authors of this study globally test the culture of honor hypothesis, which proposes that societies with traditional herding practices developed value systems that encourage revenge and violence. Because their livelihood depends on a mobile asset, herders are more vulnerable to theft and may be more likely to turn to violence or aggressiveness to defend their animals. The authors found dependence on herding to be significantly associated with both past and contemporary conflict and punishment.

A general theory of conflict and violence provides a framework for understanding the relationship between internal and external political conflict and the conditions under which they are connected. This study draws on a cross-cultural sample of 90 preindustrial societies, assessing whether these two forms of conflict covary and identifies the social factors that shape their associations. Using a multiple regression analysis reveals a moderate positive relationship overall, but the strength and nature of these relationships depend on specific societal characteristics. Societies in which internal and external conflict can occur and fall together display remarkedly different patterns of cross-cutting ties compared to those in which the two forms operate independently. Structural features of social organization emerge as key determinants of whether aggression is directed inward, outward, or both. In contrast, dispositional (psychocultural) traits are strong predictors of overall conflict levels but do not distinguish between internal and external targets. Together, these findings showcases the importance of integrating structural and dispositional factors in explaining patterns of political violence.

In this paper, the authors argue that polygyny creates social inequality in which economically advantaged men marry multiple women and economically disadvantaged men marry late in life or potentially never. The institution of polygyny results in a higher proportion of single men without families ("excess men"), who, the authors propose, may turn to violence to achieve higher wealth or prestige. Following this theory, the authors hypothesize that societies with more polygynous neighbors will be at higher risk for intergroup conflict, for which they find robust support. They also find that young men in polygynous societies, who are more likely to be economically disadvantaged and have less prestige, are also more likely to feel as though they are treated unequally and more ready to resort to violence, supporting the authors' theorized underlying mechanism.

The authors of this study investigate both intimate partner violence (IPV) in Africa and tolerance towards it. Merging Demographic and Health Survey data with information from the Ethnographic Atlas, they take into account a wide range of ancestral characteristics that could influence domestic violence today, including precolonial economic roles and marriage traditions. Their findings indicate that societies in which men were dominant in subsistence and/or had androcentric marital practices have more IPV today, and more acceptance of it. They also find an interesting gender gap in acceptance of IPV, in which women are more likely than men to justify domestic violence.
