The effects of morality, social dominance orientation, and relational maturity on perception of intimate partner violence (IPV) were investigated in a sample of 300 Japanese male in their 30s. After reading a description of an IPV scenario involving a hypothetical couple, participants responded to items of victim (i.e., wife) blame. We expected that men with higher self-rated morality, higher social dominance orientation and less mature relationships with their own partners would show the highest victim blame. However, we found that men who rated themselves as having high morality blamed the victim more than those who did not, regardless of their dominance orientation and relational maturity. The results suggested that morality might play an important role in IPV.
