Will Black outlines up-to-date information about psychopathy and ties it with insights about powerful psychopaths within influential spheres. He intigrates anthropological perspectives to applied mental health issues and makes a significant contribution to the subject of psychopathy by advancing the idea of 'psychopathic cultures', in which groups of all sizes can reflect characteristics of psychopaths. In doing so, Black creates a new level of awareness of the dangers psychopaths pose to vulnerable groups and societies at large. Examples of pathological cultures given range from those within families to paedophile rings, political organisations, media empires and finance. Black also illustrates inherent weaknesses in these pathological cultures and explains how critics of toxic organisations have more power than ever before to expose wrongdoing.
