Is psychopathy a mental disorder?
We strongly dispute the assertion that psychopathy is not a disorder. Psychopathy is a mental disorder according to both the Wakefield definition cited in this study and American Psychiatric Association criteria (American Psychiatric Association, 2000). More studies of the harm done to family members by psychopathic individuals are needed. Psychopathy may persist because it represents a dominance-related spandrel and because of nepotistic help to, not from, psychopathic individuals.
