Despite the concerns of some legal scholars, more empirical evidence suggests that there is indeed such a thing as juvenile psychopaths. Moreover, such youth psychopathy is predicative of adult criminality and violence. A new meta-analysis by Dr. John Edens and colleagues from Southern Methodist University published in February's issue of Law and Human Behavior reveals a modest to strong relationship between Hare's psychopathic traits and future criminal behavior. Added to prior studies suggesting psychopathy is largely heritable, the youth psychopathy construct provides interesting questions for criminal law scholars and incapacitation proponents.
