What is it about?
Evolutionary psychologists claim that “. . . stepparenthood is the strongest risk factor for child abuse ever identified” (Pinker, 1997, p. 434). Yet in the child maltreatment and homicide literature there is remarkably little mention of stepparents among the many factors that have been shown to contribute to its etiology (e.g., Cicchetti & Toth, 2016; Stith et al., 2009). Quite simply, both sides cannot be right: Either stepparenthood is a very strong risk factor or it is not. In this study we investigated this issue by replicating arguably the single most influential of the evolutionary psychologists’ studies of stepparents and child abuse (Daly & Wilson, 1994) to test possible alternative explanations of their findings.
