There has been much research investigating parenting as a function of genetic relatedness to the child, with a focus on male behavior, but the nature of these sex differences is hard to evaluate. We devised a hypothetical scenario that was as similar as possible for men and women to test whether, even in such a scenario, sex differences would remain strong. Participants were presented with the discovery that a child that s/he believed to be theirs was not carrying their own genes. Irrespective of sex, participants (n = 1007) were more upset when the baby was not genetically related to them than when the child was genetically related but the sex gamete was not from a chosen donor. Women were more upset than men in both scenarios, but were more likely to want to keep the baby. The results are discussed with reference to evolved and rational mechanisms affecting parenting.

The current study (N = 336) extends this by manipulating the apparent levels of Dark Triad traits in targets and correlating mate choice in these targets with individual differences in the Dark Triad traits in actors. As expected, both sexes preferred partners low in the Dark Triad traits for long-term mating, while those high in these traits were preferred for one-night stands. However, women high in psychopathy considered the Dark Triad traits in potential male partners more physically attractive and desirable for an one-night stand, as well as a potential husband. Men who were high on psychopathy were likewise attracted to psychop-athy in potential mothers. Our findings are discussed from an evolutionary personality paradigm.

In an on-line study (N=323),we investigated the relationship between the Dark Triad and different facets of interoception, such as awareness and trust in body sensations, the capacity to regulate attention, and an awareness of mind–body integration. When we controlled for shared variance between the Dark Triad traits, narcissism emerged as a positive predictor for all but one facet of interoception. Primary psychopathy was a positive predictor of attention regulation, whereas secondary psychopathy was a negative predictor of awareness of body sensation and attention regulation. Machiavellianism emerged as a negative predictor of trusting body sensations. The findings are discussed within an evolutionary framework.

In the present questionnaire study, relationships between sex, domain-specific risk-taking, and primary and secondary psychopathy were investigated in an on-line sample of 373 (75 male) participants. Secondary psychopathy related to more diverse risk-taking than primary psychopathy, supporting the competitive disadvantage-theory of psychopathy (Mealey, 1995). In men, primary psychopathy had an association with between-group risk, and in women, secondary psychopathy correlated with within-group risk. The results are discussed with regards to sex differences in psychopathy and risk from evolutionary perspective.
