Episode notes

Today we’re putting The Tonearm's needle on author and behavioral scientist Michael Hallsworth.

Michel has spent the last two decades applying behavioral science to real-world problems at the Behavioural Insights Team. He's held positions at Princeton, Columbia, Imperial College London, and the University of Pennsylvania.

Michael's new book, The Hypocrisy Trap, takes on something we all recognize instantly but rarely understand: why we're so quick to spot hypocrisy in others yet are blind to it in ourselves. He shows how our hunt for inconsistency has become a weapon in politics and daily life, one that actually breeds more of what it tries to eliminate. The book reveals why some hypocrisy might be unavoidable in functioning democracies, and how our relentless attacks on it can backfire in dangerous ways.

We talk about double standards, the psychology behind moral accusations, and why the most authentic-seeming politicians might be the most deceptive. Michael explains how we can tell the difference between hypocrisy that harms society and the everyday compromises that allow us to function together.
