The Sunday Times bestseller ‘I found myself laughing like the proverbial loon for page after page’ Will Self _____ What if society wasn’t fundamentally rational, but was motivated by insanity? This thought sets Jon Ronson on an utterly compelling adventure into the world of madness. Along the way, Jon meets psychopaths, those whose lives have been touched by madness and those whose job it is to diagnose it, including the influential psychologist who developed the Psychopath Test, from whom Jon learns the art of psychopath-spotting. A skill which seemingly reveals that madness could indeed be at the heart of everything . . . Combining Jon’s trademark humour, charm and investigative incision, The Psychopath Test is both entertaining and honest, unearthing dangerous truths and asking serious questions about how we define normality in a world where we are increasingly judged by our maddest edges. Jon Ronson is an award-winning writer and documentary maker. He is the author of many bestselling books, including So You’ve Been Publicly Shamed, The Psychopath Test, Lost at Sea, The Men Who Stare at Goats and Them: Adventures with Extremists. His acclaimed podcasts include Things Fell Apart and The Butterfly Effect, and he co-wrote the screenplays for the movies Okja and Frank. He lives in New York.
