Abstract: Although casual sex is increasingly socially acceptable, negative stereotypes toward women pursuing casual sex appear to remain pervasive. Specifically, a common trope in media (e.g., television, film) is that such women have low self-esteem. Despite robust work on prejudice against women who engage in casual sex, little empirical work investigates the lay theories individuals hold about such women. Across six experiments with US participants (N = 1,469), we find that both men and women stereotype women (but not men) who have casual sex as having low self-esteem. This stereotype is held explicitly and semi-implicitly, not driven by individual differences in religiosity, conservatism, or sexism, is mediated by inferences that women having casual sex are unsatisfied with their mating strategy, yet persists when these women are explicitly described as choosing to have casual sex. Finally, it appears unfounded; across experiments, these same participants’ sexual behavior is uncorrelated with their own self-esteem.
