ABSTRACT
This chapter discusses the evolutionary psychology, discuss sex differences from this perspective, and detail how certain personality traits could represent the psychological mechanisms behind interpersonal violence. A sociologist might suggest interpersonal violence is a function of income inequality and other institutional factors. Geneticists might suggest interpersonal violence is a function of genes that code for aggression and testosterone. In short, the meaning of life for an evolutionary psychologist is about increasing the number of offspring one leaves on the planet. The predictions are examined in a general sense, as well as in the context of intimate relationships and, given the overlap between the Dark Triad and the Big Five personality traits, and overlap between these traits and interpersonal violence, any contamination from the Big Five traits is controlled. The Dark Triad traits were positively correlated with virtually every manifestation of interpersonal violence.
