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.

About the hosts:
Thom and Aidan left boring, stable careers in law and tech to found FarmKind, a donation platform that helps people be a part of the solution to factory farming — regardless of their diet. While the podcast isn’t about animal welfare, it’s inspired by their daily experience grappling with a fundamental question: Why do people so rarely change their minds, even when confronted with compelling evidence? This curiosity drives their exploration of intellectual humility and the complex factors that enable (or prevent) meaningful belief change.

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.
