Clarifying Gender Differences in Moral Dilemma Judgments: The Complementary Roles of Harm Aversion and Action Aversion

Moral dilemmas entail situations where decisions consistent with deontological principles (following moral rules) conflict with decisions consistent with utilitarian principles (maximizing overall outcomes). Past work employing process dissociation (PD) clarified that gender differences in utilitarianism are modest, but women are substantially more deontological than men. However, deontological judgments confound two motivations: harm aversion and action aversion. The current work presents a mega-analysis of eight studies (N = 1,965) using PD to assess utilitarian and deontological response tendencies both when deontology entails inaction and when it requires action, to assess the independent contributions of harm aversion and action aversion. Results replicate and clarify past findings: Women scored higher than men on deontological tendencies, and this difference was enhanced when the deontological choice required refraining from harmful action rather than acting to prevent harm. That is, gender differen...
