Some scholars might contend that Yeo-Thomas embodied the successful psychopath, sometimes termed the adaptive or subclinical psychopath: an individual who displays many of the core features of psychopathic personality (psychopathy) while achieving success. The lion’s share of the field’s knowledge about psychopathy has stemmed from individuals ensconced safely behind prison walls, most of whom are presumably unsuccessful (Lilienfeld, 1994). Nevertheless, the past decade has witnessed growing interest in an intriguing possibility: Perhaps many psychopathic individuals are thriving in the everyday world, in some cases occupying the higher echelons of selected professions. Indeed, Hare (1993) posited that incarcerated psychopaths “represent only the tip of a very large iceberg” (p. 115).
