While the literature generally finds that women are more commonly the victims of domestic violence, some research suggests that rates of physical aggression within the context of dating and marriage tend to be similar for men and women, or that women are more likely to commit domestic violence against a partner; this is known as gender symmetry. However, such data generally shows that men tend to inflict the greater share of injuries. Critics have used studies such as Dekeseredy et al. to argue that "studies finding about equal rates of violence by women in relationships are misleading because they fail to place the violence in context; in other words, there is a difference between someone who uses violence to fight back or defend oneself and someone who initiates an unprovoked assault."
