Psychopathy

Psychopathy, or psychopathic personality, is a personality construct characterized by impaired empathy and remorse, and persistent antisocial behavior, along with bold, disinhibited, and egocentric traits. These traits are often masked by superficial charm and immunity to stress, which create an outward appearance of normality. Hervey M. Cleckley, an American psychiatrist, influenced the initial diagnostic criteria for antisocial personality reaction/disturbance in the Diagnostic and Statistical Manual of Mental Disorders (DSM), as did American psychologist George E. Partridge. The DSM and International Classification of Diseases (ICD) subsequently introduced the diagnoses of antisocial personality disorder (ASPD) and dissocial personality disorder (DPD), respectively, stating that these diagnoses have been referred to (or include what is referred to) as psychopathy or sociopathy. The creation of ASPD and DPD was driven by the fact that many of the classic traits of psychopathy were impossible to measure objectively. Canadian psychologist Robert D. Hare later re-popularized the construct of psychopathy in criminology with his Psychopathy Checklist. Although no psychiatric or psychological organization has sanctioned a diagnosis titled "psychopathy", assessments of psychopathic characteristics are widely used in criminal justice settings in some nations and may have important consequences for individuals. The study of psychopathy is an active field of research. The term is also used by the general public, popular press, and in fictional portrayals of psychopaths. While the abbreviated term "psycho" is often employed in common usage in general media along with "crazy", "insane", and "mentally ill", there is a categorical difference between psychosis and psychopathy.
