Spencer Greenberg is an entrepreneur, mathematician, and social scientist who has dedicated his career to helping people think more clearly and make better decisions.

After years of building tools to improve reasoning from personality tests to structured debate platforms, Spencer realised that the biggest challenge isn’t just giving people good information. It’s getting them to actually use it. Today, his work focuses on making psychological insights and rational thinking tools practical, engaging, and easy for anyone to apply in everyday life.

We explore why Spencer cares so deeply about truth-seeking, what makes people resistant to changing their minds, and how his projects (like Clearer Thinking and GuidedTrack) are helping people question assumptions, explore alternative perspectives, and live more intentionally.

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.

Freddie deBoer is a writer, academic, and former teacher whose research and experience challenge one of society’s most deeply held beliefs: that education is the great equaliser.

After teaching students at every level - from special education classrooms to college lecture halls - Freddie had a change of heart. He came to believe that intelligence is largely inherited, that academic ability is far more stable than we like to admit, and that expecting every child to succeed in the same system can actually be cruel.

We explore the moment that led Freddie to question the promise of education, why well-funded interventions and elite schools rarely change outcomes, and what a more humane and realistic approach to schooling could look like.

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.
