Stephen Greenspan has dedicated a large part of his career to explaining why people act gullibly. As a psychologist and author, he’s drawn from research, literature and his own personal experience as a victim of Bernie Madoff to help explain the psychological underpinnings of why otherwise smart people do stupid things. On this week’s episode, Nicholas takes to Stephen about his work, his life and the reason why, if you say the word gullible really slow, it sounds like word oranges.
