<unk> , sometimes considered synonymous with sociopathy, is characterized by persistent antisocial behavior, impaired empathy and remorse, and bold, disinhibited, and egotistical traits. Different conceptions of<unk>  have been used throughout history that are only partly overlapping and may sometimes be contradictory. 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<unk>  or sociopathy. The creation of ASPD and DPD was driven by the fact that many of the classic traits of<unk>  were impossible to measure objectively. Canadian psychologist Robert D. Hare later repopularized the construct of<unk>  in criminology with his<unk>  Checklist. Although no psychiatric or psychological organization has sanctioned a diagnosis titled<unk> ", assessments of<unk> c characteristics are widely used in criminal justice settings in some nations and may have important consequences for individuals. The study of<unk>  is an active field of research. The term is also used by the general public, popular press, and in fictional portrayals. While the term is often employed in common usage along with "crazy", "insane", and "mentally ill", there is a categorical difference between psychosis and<unk> .
