In this episode, we focus on REASON. I interview Lee McIntyre, the author of "How to Talk to a Science Denier." We talk about his previous book, Post-Truth, which discusses how factors ranging from the decline of traditional media to the rise of post-modernism in the humanities undermined our shared understanding of truth. The book also has a great overview of classic findings on cognitive bias, and in this dialogue he gives us an update from the latest psychology research. Professor McIntyre is Research Fellow at the Center for Philosophy and History of Science at Boston University and an Instructor in Ethics at Harvard Extension School.
