Shankar Vedantam: The Hidden Brain

Washington Post columnist Shankar Vedantam discusses his book "The Hidden Brain: How Our Unconscious Minds Elect Presidents, Control Markets, Wage Wars, and Save Our Lives." The hidden brain is Vedantam's shorthand for a host of brain functions, emotional responses, and cognitive processes that happen outside of our conscious awareness, but that have a decisive effect on how we behave.
