The statement that would be supported by scientists who research cycles of violence across generations in a family is:
Child victims of abuse are more likely to become abusive as adults.
This statement reflects the findings of research that indicates a correlation between experiencing abuse as a child and the likelihood of becoming an abuser in adulthood. The other statements are less supported by empirical evidence. For example, not all victims of childhood abuse become abusers, violence is not directly passed down genetically like a disorder, and not all abusers intentionally teach their children to be violent.
