How to Spot a Sociopath

16 key behavioral characteristics that define sociopaths/psychopaths and others with antisocial disorders.

Psychologists vie to enumerate the facets of sociopathy. Joseph Newman argues that the sociopath has an attention bottleneck that allows him to focus only on one activity or train of thought, to the exclusion of others. Researchers, including Howard Kamler, say that the sociopath lacks not "moral" identity but self-identity altogether. Yet nowhere do I recognize myself more than in Hervey Cleckley's clinical profiles. In The Mask of Sanity, published in 1941, Cleckley distilled what he believed to be the 16 key behavioral characteristics that defined psychopathy. Most of these factors are still used today to diagnose sociopaths/psychopaths and others with antisocial disorders. (Psychopathy and sociopathy are terms with an intertwined clinical history, and they are now largely used interchangeably. The DSM excludes both, in favor of antisocial personality disorder.)
