How to change minds… and have your mind changed

The human brain has evolved over hundreds of thousands of years to the point where we could put a man on the Moon and explore the universe. A new book raises the question, as one reviewer put it, "If humans are so smart, why are we so dumb?" A new book that addresses that question is The Influential Mind: What the Brain Reveals about Our Power to Change Others. Warren Olney speaks with the author, Tali Sharot, a neuroscientist who founded the Affective Brain Lab at University College London, about the science of why emotion trumps reason.
