A new model of psychopathy

The concept of psychopathy has long been of interest within the criminal justice  system, often presented as the causal antecedent to serial violent and sexual offences. Despite  this, psychopathy has remained difficult to assess, with research in the area compromised by  the absence of an established definition of the disorder. The first comprehensive  conceptualisation of psychopathy was proposed by Hervey Cleckley in 1941. Cleckley  suggested the prototypical psychopath to be characterised by the following 16 traits:  superficial charm, absence of delusions, absence of “nervousness”, unreliability,  untruthfulness, lack of remorse and shame, antisocial behaviour, poor judgement and failure  to learn by experience, pathological egocentricity, poverty in affective reactions, loss of  insight, unresponsiveness in interpersonal relations, fantastic and uninviting behaviour, suicide rarely carried out, impersonal sex life, and failure to follow any life plan.
