Moral decision making is complex and depends on individuals and their environment (Kimhi & Kasher, 2015), and what is morally permissible in warfare differs from what is morally permissible in everyday life (Watkins, 2020). Across 2 studies (N ϭ 511), we assessed how masculine honor beliefs (MHBs), beliefs in pure good (BPGs) and evil (BPEs), and the dark triad (DT) relate to decision making in military and nonmilitary moral dilemmas. We hypothesized MHBs, BPEs, and DT would predict more confidence, wanting to be the hero, and less guilt with BPEs and DT also predicting more distrust of others and BPGs predicting more guilt. Our findings were largely consistent with these hypotheses. Our findings suggest nonmilitary dilemmas were easier to resolve than military dilemmas, given higher reported confidence and more utilitarian decisions. Overall, individual differences in MHBs, BPGs, BPEs, and DT relate to different motivations in decision making (e.g., to be the hero).
Public Significance StatementMoral decision making is difficult, and even more so when lives are stake. Because moral decision making is multifaceted, the current research assessed how certain individual differences (i.e., masculine honor beliefs, beliefs in pure good and evil, and the dark triad of personality) influence decisions made in hypothetical life-or-death moral dilemmas that took place in both military and nonmilitary settings. Additionally, we inquired about the intrapersonal factors related to one's decisions (e.g., confidence, guilt). These findings provide insight as to how lay persons resolve dilemmas differently in military versus nonmilitary settings and how the emotional toll varies as a result. In other words, this research helps further distinguish the nuances in military moral decision making versus nonmilitary moral decision making.Keywords: masculine honor beliefs, beliefs in pure good, beliefs in pure evil, moral decision making, utilitarianism Moral decision making is complex because both individual factors (e.g., authoritarian personality) and environmental factors (e.g., type of threat posed) influence decisions made in moral dilemmas (Kimhi & Kasher, 2015). Specifically, the norms guid-ing behavior in "large-scale, violent, and intergroup conflict" differ from those guiding daily behavior (Watkins, 2020, p. 1). Accordingly, the military has specific guidelines for fair and just conduct in combat (Hurka, 2005;Orend, 2008;Watkins, 2020). Editor's Note.
