Journalist Jon Ronson has made his living writing about real people whose lives read like science fiction. “The Men Who Stare at Goats” is probably his best known work. Centering on the U.S. military’s efforts to develop paranormal warfare techniques, it was made into a Hollywood movie starring George Clooney and Jeff Bridges. Ronson’s newest work explores something just as strange and fascinating. It’s called “The Psychopath Test: A Journey Through the Madness Industry.” As the title suggests, it looks at how madness is measured, and sheds light on how many seemingly normal people are actually psychopaths.
