  • Several of the 20 items require the examiner to rate personality traits that we historically think of when we use the term "psychopath," such as whether the person shows a lack of remorse or guilt, appears callous, seems superficially charming, and has an inflated sense of self-worth i.e., the personality component.

  • My primary reservation about using the PCL-R in the criminal justice system is that research suggests its personality component and the label "psychopath" are highly stigmatizing, evoking images of fictional villains like Hannibal Lecter as well as real-world serial killers such as Ted Bundy and Jeffrey Dahmer.

  • One question people often ask is if there is a difference between a sociopath and a psychopath. Barring the fact that many psychologists deny the existence of either, in a clinical setting the difference is purely semantic. Robert Hare has pointed out that sociologists are more likely to focus on the environmental or socially modifiable facets of the disorder, so prefer the term sociopathy, whereas psychologists and psychiatrists prefer to include the genetic, cognitive, and emotional factors as well as the social factors when making a diagnosis, and therefore would opt for psychopathy. Since I am a brain scientist and am interested in the genetic and neurological causes of this personality disorder, I will use the term psychopath for the purposes of this book.
