The (Un)Attractiveness of Dark Triad Personalities: Assessing Fictitious Targets for Short- and Long-Term Relationships

Most of the literature on the attractiveness of Dark Triad traits has focused on female mate choice and low versus high trait levels. This study assessed how people with male and female sexual preferences evaluate potential romantic partners who display either low, medium, or high levels of Dark Triad traits for short-term and long-term relationships. Nine fictitious persons in the form of vignettes (with facial images) were presented to every participant. The faces were selected from an existing image bank and matched for physical attractiveness. Study 1 (n = 478) used a fixed composition for face and trait description, while the composition for Study 2 (n = 793) was randomized. Mixed-effects modelling was implemented for both studies. Study 1 demonstrated people with a male preference perceived medium levels of all traits as the most attractive for short-term relationships. Low levels of Narcissism were perceived as the most attractive for long-term relationships by both groups. For Study 2, the low levels were perceived as the most attractive for both types of relationships by both groups. Findings from Study 1 were consistent across previous Dark Triad attractiveness literature, while findings from Study 2 contradicted them. Differences between the two studies are discussed.
