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 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.
