Josh Greene is a Harvard psychologist, neuroscientist, and philosopher whose research has reshaped how we understand moral decision-making. But after publishing his book Moral Tribes, Josh changed his mind - realizing that explaining why people clash wasn’t enough. Since then, he’s focused on building tools to reduce division and promote cooperation.

We explore how Josh made that shift, what it means to be a “moral engineer,” and how projects like Giving Multiplier and a bipartisan trivia game are helping people bridge divides in an increasingly polarised world.

Today we're joined by Joe Walker, host of The Joe Walker Podcast, where he conducts refreshingly in-depth conversations with the world's deepest thinkers. Joe has spoken with figures like Noam Chomsky, Daniel Kahneman, and Nassim Taleb, and is known for his extraordinary preparation process - sometimes investing over 200 hours of deep study for a single conversation.

We'll be exploring Joe's remarkable system for going from complete novice to discussing complex subjects with world experts in a matter of weeks – a process that includes textbooks, tutoring sessions, hundreds of flashcards, and in at least one case terraforming a hotel room with post-it notes. We'll also discuss how preparing for and having these conversations has shaped Joe's views on two topics: the risk posed by nuclear weapons, and the question of how people actually form and change their beliefs.

We're joined by Noah Smith, an economist, former Bloomberg Opinion writer and now influential economic commentator through his blog Noahpinion.

In this conversation, we explore how Noah has changed his mind to be far less hopeful about making political progress and how he came to think — even before Trump’s election — that we were entering a decade of conservatism. We also discuss Noah’s unusual ability to change his mind in public and admit where he thinks he’s got a call wrong.

We're joined by Mark Bittman, whose career has taken him from America's most beloved cookbook author to one of our most outspoken food system critics, arguing that the modern food system is degrading human and planetary health.

We'll be discussing how Mark changed his mind from seeing the problem with the food system as primarily a matter of individual consumer choices to recognizing them as deeply embedded in corporate power and government policy. We’ll explore how this fundamentally changed his approach to fixing our food system: pivoting from a focus on teaching people how to cook well, to focusing on the structures and systems that make eating well hard for so many people.

Josh Szeps is a seasoned broadcaster who left traditional media to start Uncomfortable Conversations, a project which aims to create a space for people who disagree on sensitive issues to engage in good-faith dialogue where participants and listeners can understand different perspectives, potentially change their minds, and discover common ground.

In this episode, we explore how Josh's views have evolved on how to create an information ecosystem that promotes understanding and mutual respect, rather than confusion and division. We'll discuss the different roles that traditional and new media play, and the roles they ought to play given their comparative advantages. We’ll discuss the value of public disagreement, the craft of doing it constructively, and its limits for actually changing our minds. We'll also discuss the boundaries of free speech and how to navigate a world where attention, not truth, is often the currency that matters most.

Psychologist and author Melanie Joy joins us to explore how unconscious belief systems shape our behavior. While known for developing the concept of 'Carnism' - the invisible belief system conditioning people to eat certain animals - her work extends to examining psychological dynamics behind various forms of oppression and dysfunction. After decades in academia and activism, Joy is now turning to fiction writing, believing storytelling may be more effective at helping people recognize and transform harmful belief systems.

Clinical psychologist and New York Times best-selling author Rick Hanson joins us to discuss how remarkably plastic our brains are, despite how fixed they often feel. We discuss what's doing on mechanistically when people change their minds, and what we can learn from this about how to be more open to change as individuals.
