The Hypocrisy Trap: How Changing What We Criticize Can Improve Our Lives (October 2025, The MIT Press)

Michael Hallsworth, Chief Behavioural Scientist, Behavioural Insights Team

How our desire to stamp out hypocrisy is backfiring—and how learning to target our criticisms better can improve our politics, business, and personal relationships.

In our increasingly distrusting and polarized nations, accusations of hypocrisy are everywhere. But the strange truth is that our attempts to stamp out hypocrisy often backfire, creating what Michael Hallsworth calls The Hypocrisy Trap. In this groundbreaking book, he shows how our relentless drive to expose inconsistency between words and deeds can actually breed more hypocrisy or, worse, cynicism that corrodes democracy itself.

Through engaging stories and original research, Hallsworth shows that not all hypocrisy is equal. While some forms genuinely destroy trust and create harm, others reflect the inevitable compromises of human nature and complex societies. The Hypocrisy Trap offers practical solutions: ways to increase our own consistency, navigate accusations wisely, and change how we judge others’ actions. Hallsworth vividly shows that we can improve our politics, businesses, and personal relationships if we rethink hypocrisy—soon.
