AbstractThis research investigated the motivational underpinnings of attitudes towards weapon ownership. We propose that people who have a strong need for closure (NFC) would be more likely to approve of weapon ownership, but that this relationship would be serially mediated by the endorsement of binding moral foundations and fear of immigrants. Specifically, heightened NFC would promote moral concerns for the safety of one's group (i.e., the binding foundations), which, in turn, would trigger fear of immigrants, or the belief that immigrants threaten one's society. In turn, fear of immigrants would generate the approval of defensive means (i.e., weapons). We tested this serial mediation model in three studies with Italian and US samples, where NFC was both measured (Studies 1 and 3; N = 286 and N = 278) and experimentally induced (Study 2; N = 290). The results supported the proposed model. These findings suggest that a high NFC might explain individuals’ approval of weapon ownership through their moral priorities, which heighten their prejudice towards immigrants.
