This study explores several correlates of interpersonal violence. Multiple regression analysis suggests that socialization for aggression in boys in late childhood is the strongest predictor of higher rates of homicide and assault. Path analysis suggests that socialization for aggression is a consequence, not a cause, of war.

The article tests theories that may explain why warfare frequency varies from society to society. The focus is on ecological problems, particularly different kinds of resource scarcity, but social and psychological theories are also tested with both bivariate and multivariate analyses. Because unpredictable disasters are such a strong predictor in nonstate societies, the authors theorize that war may mostly be caused by a fear of nature.

This article examines resource problems and warfare in a sample of societies from eastern Africa. The frequency and predictability of resource problems are examined, as are two other dimensions of warfare: resource-taking and commission of atrocities. Differences between state and nonstate societies, as well as pacified and non-pacified societies, are also examined and shown to affect associations between resource and warfare variables.

This article presents two evolutionary models that may explain relationships between war and socialization of children: the "environmentally contingent reproductive strategy" (ECRS) model put forward by Draper and Harpending (1982), and a model put forward by Carol and Melvin Ember. Results do not provide support for the hypotheses involving father-infant sleeping proximity derived from the ECRS model. The authors also find some inconsistencies with their own model.

The authors construct a mathematical model from which they generate their main hypothesis that resource unpredictability should be associated with frequency of warfare. A cross-cultural test of this hypothesis was performed by Ember and Ember (1992). The authors critique these findings for state societies and test and alternate hypothesis for application to state societies.

This paper reviews the results of the author's cross-cultural studies of war and aggression and their implications for prehistory.

This paper presents empirical tests of two theories put forth to explain violence toward women. The first predicts that warfare promotes socialization for aggression and legitimizes violence toward women, while the second predicts that violence works as a way to control potential for female infidelity. An association is found between high male-to-female sex ratio and violence towards women, suggesting support for the second theory over the first, which is consistent with more narrowly-focused studies by Avakame (1999), Bose et al. (2013), and D'Alessio & Stolzenberg (2010).

This paper supports Beatrice B. Whiting's (1965) sex-identity conflict hypothesis which suggests a relationship between males' early identification with their mothers and male violence. Authors find that, in addition to socialization aggression, frequency of homicide/assault is significantly related to father-infant sleeping distance, particularly when residence is not matrilocal and/or warfare is more than occasional.

This study investigates variation in rates of violence against women, primarily interested in two main hypotheses: the Culture of Violence Hypothesis and the Functional Violence Hypothesis. Using the SCCS along with variables from Broude & Greene (1976) and Ember & Ember (1992), the study concluded that warring societies were associated with a greater intolerance of rape, contradicting the Culture of Violence Hypothesis, whereas wife beating, as well as tolerance towards rape, increased with scarcity of women, in line with the evolutionary Functional Violence Hypothesis.

This article tests several hypotheses related to the presence or absence of polygyny. Results suggest a negative relationship between polygyny and male provisioning, and positive relationships between polygyny and warfare, interpersonal aggression, and pathogen stress.
