Tuesday, our guest is the social psychologist Jonathan Haidt, whose latest book sets out to explain the root causes of the divisions in our society. At the heart of his argument is the idea that the human mind is designed to "do" morality. But when we separate into tribes – say political affiliations or religious denominations – we focus on different moral foundations. Haidt joins us to explain why he says we need the insights of liberals and conservatives to flourish as a nation. [Rebroadcast]
NOTE: Tuesday's scheduled interview with naturalist Joel Greenberg about passenger pigeons has been postponed due to illness.
Jonathan Haidt is a professor at New York University Stern School of Business. He's the author of The Righteous Mind: Why Good People Are Divided by Politics and Religion and The Happiness Hypothesis
