Host Susie Meister interviews neuroscientist and author of The Psychopath Inside: A Personal Journey Into the Dark Side of the Brain, Dr. James Fallon, who discovered accidentally that he has the brain genetics of a psychopath. Fallon describes what it was like to discover his own genetic predisposition of psychopathy, and why he believes he turned out to be a successful, non-violent, family man instead of a monster. Fallon also discusses how psychopaths operate in and see the world, and why these genes have been useful historically. Meister and Fallon talk about serial killers and the brain makeup that contributes to these behaviors.
