Inferring political and religious attitudes from composite faces perceived to be related to the dark triad personality traits

Abstract

We used composite face images perceived to have different levels of Dark Triad personality traits (narcissism psychopathy and Machiavellianism) and asked participants to predict these target individuals' religious and political identities. In Study 1 (N = 550) Turkish participants rated faces with higher levels of perceived Dark Triad traits as less likely to be religious to believe in God and more likely to be left-winger and to vote for a left-leaning party in all categories except for male narcissism. In a pre-registered follow-up study (N = 1001) we recruited a nationally representative US sample and replicated the same results with minor differences regarding male and female narcissism and voting preferences. Participants' own political and ideological identities and their stereotypical evaluation of the target groups were mostly ineffective in explaining their predictions. The results suggest that people can perceive faces with higher levels of Dark Triad traits as less religious and less conservative. © 2021 Elsevier B.V. All rights reserved.
