To the extent that sex differences are mediated by mechanisms such as sex-roles and beliefs, individual differences in these more proximate traits should account for significant portions of relevant sex differences. Differences between women and men in reactions to sexual and emotional infidelity were assessed in a large sample of participants (n = 477), and these target reactions were evaluated as a function of many potential proximate mediators (infidelity implications beliefs, gender-role beliefs, interpersonal trust, attachment style, sociosexuality, and culture of honor beliefs) and as a function of participant sex. Results found a consistent sex difference that was not mediated by any other variables, although a handful of other variables were related to male, but not female, individual differences. These findings suggest particularly promising directions for future research on integrating evolutionarily based sex differences and proximate individual differences.

We explored between-country and within-country variability in abortion attitudes, using country-level factors (e.g., gender equality) and individual-level factors (e.g., gender role attitudes) as predictors. Participants from Mexico ( N = 215), India ( N = 215), the United States ( N = 215), and the United Kingdom ( N = 206) were recruited via Qualtrics Panels. Regression models and ANOVAs were used to assess whether estimates of gender inequality, gender role attitudes, motherhood norms, belief in big/moralizing gods, and sexual strategy were associated with abortion attitudes. As predicted, individuals living in countries with greater gender inequality, and more restrictive abortion policy, reported more restrictive abortion attitudes and stronger support for banning abortion. Furthermore, individuals who endorsed more traditional gender role ideologies, who reported belief in big/moralizing gods and who used long-term sexual strategies also reported more restrictive abortion attitudes and stronger support for banning abortion. Exploratory analyses highlight how these relationships vary as a function of cultural context. We can conclude that both contextual factors (e.g., local abortion legislation and gender inequality) as well as individual factors (e.g., gender role attitudes and religious/spiritual belief) shape people’s attitudes toward abortion. Implications regarding the bidirectional relationship between attitudes and policy in reproductive health are discussed.

We explore abortion access, abortion experiences, and abortion stigma. We emphasize global perspectives on abortion diversity and the relationship between pregnancy norms and expectations, abortion stigma, and practical constraints on reproductive freedom. Evolutionary psychological, clinical psychological, and social-psychological perspectives illuminate how abortion decisions are shaped by strategies to optimize survival and success, support services that emphasize the costs and risks of pregnancy termination, and pronatalist norms and punishment of departures from those expectations. We call for future abortion research that integrates multiple subfields in psychology and is rooted in an intention to effect public policy and social change that promotes reproductive autonomy.
