How common is psychopathy? |
Hare estimates that about 50 to 75 percent of the prison population meets criteria for antisocial personality disorder, but only 15 to 25 percent exceed the cut-off point for psychopathy. Hare also estimates that psychopaths make up about one percent of the general population. Thus, psychopathy appears to be a more severe disorder than antisocial personality disorder, but fortunately a less common one.
