The role of “dark personalities” (narcissism, Machiavellianism, psychopathy), Big Five personality factors, and ideology in explaining prejudice

The so-called Dark Triad (narcissism, Machiavellianism, psychopathy) represent correlated subclinical personality traits capturing “dark personalities”. How might darker personalities contribute to prejudice? In the present study (n = 197), these dark personality variables correlated positively with outgroup threat perceptions and anti-immigrant prejudice. A proposed two-stage structural equation model, assuming indirect personality effects (Dark Personality, Big Five) on prejudice through ideology and group threat perceptions, fit the data well. Specifically, a latent Dark Personality factor predicted social dominance orientation, whereas (low) Openness to Experience predicted right-wing authoritarianism; these ideological variables each predicted prejudice directly and indirectly through heightened intergroup threat. The authors recommend that personality models of prejudice incorporate both normal-range and subclinical personality predictors, in addition to ideological and social psychological mediators.
