“…Virtually all psychological research points to homophily ("like attracts like") as a general principle for mate preferences, although this principle appears to hold more strongly for hypothetically expressed than for actual preferences (Finkel, Eastwick, Karney, Reis, & Sprecher, 2012). Recent studies of individuals in committed relationships (Kardum, Hudek-Knezevic, Schmitt, & Covic, 2017), including married couples (Weiss etal., 2018), have revealed a small to medium association between partners' overall psychopathic traits, raising the possibility that the individuals who report the most attraction to prospective psychopathic partners are those with marked psychopathic traits themselves (for related evidence, see also Jonason, Valentine, Li, & Harbeson, 2011;Lamkin, Maples-Keller, & Miller, 2018;Sleep etal., 2017). Another study demonstrated that psychopathic females preferred males with high levels of Dark Triad traits (i.e., an amalgam of Machiavellianism, narcissism, and psychopathy; Paulhus & Williams, 2002) and found them more physically attractive, desirable for a casual sexual encounter, and even more suitable for marriage (Jonason, Lyons, & Blanchard, 2015).…”
