New research suggests that the criteria used to identify psychopathic traits may be inherently biased towards diagnosing males.

This bias arises from the emphasis on more visible, outward expressions of aggression and antisocial behavior, which are less frequently associated with female psychopathy. Women displaying psychopathic traits might do so in more subtle, manipulative, and relational forms, such as emotional manipulation or social aggression, which are not captured by traditional diagnostic approaches.

Earlier estimates proposed a 10:1 male-to-female ratio. Dr. Clive Boddy's research suggests that the ratio of male to female psychopaths might be closer to one to one, challenging a longstanding gender prejudice.

I believe this is a particularly significant finding in the context of domestic violence, as psychopathy also involves emotional manipulation and relational aggression. Recognizing that psychopathy in women exists and is expressed differently than in men, might help identify abusive situations that don't conform to the most recognized stereotype of physical violence.
