Here’s a special bonus episode featuring my recent conversation with Tim Harford, author, economic journalist, and host of the Cautionary Tales podcast. We discussed a story from my new book, How Minds Change, about a conspiracy theorist who was certain 9/11 was an inside job until he actually visited Ground Zero to meet architects, engineers and the relatives of the dead. Tim and I reflect on what he can teach us about those who hold strong beliefs even in the face of damning, contrary evidence and why persuasion, especially if attempted poorly, isn't always the right answer. • Hear more from Cautionary Tales at https://podcasts.pushkin.fm/ctsmart • How Minds Change: https://www.davidmcraney.com/howmindschangehome Hosted by Simplecast, an AdsWizz company.
