How happiness expectations relate to the Dark Triad traits

ABSTRACT

In samples of Americans (N = 273) and Indians (N = 194) paid through Mechanical Turk (Study 1) and British (N = 132) volunteers contacted through Reddit (Study 2), we examined how the Dark Triad traits (i.e., psychopathy, narcissism, and Machiavellianism) were associated with happiness expectations when participants imagined solving adaptive tasks. In Study 1, the traits were linked to forecasted happiness in achieving status and power and mate-seeking, with psychopathy demonstrating less happiness when pursuing slow life history tasks (e.g., avoiding diseases), whereas the other two traits led to expectations of happiness when forming social bonds, retaining mates, and avoiding pathogens. In Study 2, the traits were associated with choosing to pursue mating opportunities to induce happiness. Women expected more happiness in response to ensuring their safety over pursuing mating opportunities. We suggest happiness might be an affective feedback system that rewards people for pursuing their life history goals.
