Why You So Liddat is a show that explores the mind, our behaviour, and why we are the way we are. James Fallon has looked at the brains of psychopaths for over 20 years. He studies what makes their brains so different from ours. In 2005, the neuroscientist made a shocking discovery. He looked at his own brain scan and found out that he had the brain of a psychopath. James Fallon tells us more about that story, what defines psychopathy, and how his family dealt with the news. James also wrote about this in a book titled The Psychopath Inside: A Neuroscientist's Personal Journey into the Dark Side of the Brain.
