Abstract- Ultimate and proximate explanations of men’s physical intimate partner violence (IPV) against women have been proposed. An ultimate explanation posits that IPV is used to achieve a selfish fitness-relevant outcome, and predicts that IPV is associated with greater marital fertility. Proximate IPV explanations contain either complementary strategic components (e.g. men’s desire for partner control), non-strategic components (e.g. men’s self-regulatory failure), or both strategic and non-strategic components involving social learning. Consistent with an expectation from an ultimate IPV explanation, we find that IPV predicts greater marital fertility among Tsimane forager-horticulturalists of Bolivia (n=133 marriages, 105 women). This result is robust to using between- versus within-subject comparisons, and considering secular changes, reverse causality, recall bias and other factors (e.g. women’s preference for high status men who may be more aggressive than lower status men). Consistent with a complementary expectation from a strategic proximate IPV explanation, greater IPV rate is associated with men’s attitudes favoring intersexual control. Neither men’s propensity for intrasexual physical aggression, nor men’s or women’s childhood exposure to family violence predict IPV rate. Our results suggest a psychological and behavioral mechanism through which men exert direct influence over marital fertility, which may manifest when spouses differ in preferred family sizes.

 
Bio- Dr. Stieglitz's research aims to understand how ecological and social factors interact to influence human health. Specifically, his research addresses three questions: 1) Why do families form and function the way they do? 2) How does variability in family functioning affect health and well-being of household members? and 3) Why and how do social relationships (family and other) interact with local ecology to influence health over the life course? He is Assistant Professor at the University of Toulouse, and Program Director of Anthropology at the Institute for Advanced Study in Toulouse. He received his PhD in Anthropology from the University of New Mexico, and has 14 years of experience conducting integrated bio-behavioral research as part of the Tsimane Health and Life History Project.
