The authors stated that the 'social roles' hypothesis was inadequate in the case of child abuse committed by stepparents. The social role hypothesis states that stepparenthood is a stressful 'role' unclearly defined by societal norms, and that the stress caused by the nebulous nature of the role and the parent's consequence uncertainty is what leads to the greater incidence of abuse in such relationships. | The authors stated that the 'social roles' hypothesis was inadequate in the case of child abuse committed by stepparents.

It is not the 'role' that makes the stepparent uneasy, but the underlying conflict caused by the fact that they are expected to invest heavily in offspring that aren't their own and that they therefore do not see as worthy of such investment. | ||
Investing resources in such children may be seen as evolutionarily maladaptive, as they are | Investing resources in such children may be seen as evolutionarily maladaptive, as they are competitors for scarce resources with any children of their own that are produced by the relationship. It also creates tension because one is seen as sacrificing their own fitness interests in the favor of their partner, which is not generally seen in cases of adoption. It is common in the animal kingdom for a newly established dominant male to kill the young offspring produced by the defeated male, most notably seen in polygynous animals such as lions and gorillas. | ||
