Abstract
Although the evolution of psychopathy as a formal clinical disorder began more than a century ago, it is only recently that scientifically sound psychometric procedures for its assessment have become available. The result has been a sharp increase in theoretically meaningful and replicable research findings, both in applied settings and in the laboratory. The construct of psychopathy is proving to be particularly useful in the criminal justice system, where it has important implications for sentencing, diversion, placement, and treatment options and for the assessment of risk for recidivism and violence. Although the etiology of the predatory, cold-blooded nature of psychopathy remains obscure, the theories and methods of cognitive neuroscience and behavioral genetics promise to greatly increase our understanding of this disorder.
