Welsh journalist Jon Ronson takes on the investigation of a hoax that has connected leading scientists around the world, and this decision becomes the starting point for a journey into a world of madness. Trying to understand whose side is right, the journalist reconstructs the history of the study of psychopaths. He meets with Scientologists who are convinced of the immorality of psychiatrists and are engaged in discrediting them. Corresponds with participants and organizers of experimental treatment programs. Explores the rise and fall of the founder of forensic psychology. Takes a course with Bob Haer, who created a questionnaire to identify psychopaths. And, of course, he communicates with psychopaths of all kinds: from the “malingerer” who was stuck in a psychiatric clinic for twelve years after pretending to be insane using cliches from old films, to the legendary CEO who fired hundreds of employees of the largest productions.< /p>
