The hypocrisy trap: how changing what we criticise can improve our lives

Hosted by the Department of Psychological and Behavioural Science
In-person public event (Hong Kong Theatre, Clement House)
Wednesday 19 November 2025 5.30pm - 7pm

Our lives are full of accusations of hypocrisy — against politicians, companies, and each other. Yet despite this noise, little seems to change. Join us for this talk where Michael Hallsworth will discuss his recent book The Hypocrisy Trap: How Changing What We Criticize Can Improve Our Lives.

In discussion with Liam Delaney, Dr Hallsworth will explore how the "hypocrisy trap" — our relentless drive to expose inconsistency — either breeds more hypocrisy or exhausts our belief in shared standards altogether.

Drawing on the latest behavioural science studies, he demonstrates why accusations ratchet up over time, why they rarely convert opponents, and how purity tests can backfire. Rather than trying to eliminate hypocrisy altogether, we can find practical ways to criticize it better: distinguishing between corrosive double standards and tolerable compromises, rewarding progress over perfection, and using new tactics to become more consistent ourselves. The session connects these insights to politics, business, and everyday life, offering a toolkit for moving from outrage to outcomes.

The event will be followed by a book signing.
