Jonathan Haidt of New York University and author of The Righteous Mind talks with EconTalk host Russ Roberts about his book, the nature of human nature, and how our brain affects our morality and politics. Haidt argues that reason often serves our emotions rather than the mind being in charge. We can be less interested in the truth and more interested in finding facts and stories that fit preconceived narratives and ideology. We are genetically predisposed to work with each other rather than being purely self-interested and our genes influence our morality and ideology as well. Haidt tries to understand why people come to different visions of morality and politics and how we might understand each other despite those differences.
