Do you really know when you’re being lied to?

Most of us believe we do, but research suggests we’re far worse at detecting deception than we’d like to think.

This week, Grace is joined by Chartered Psychologist Stuart Duff to explore the fascinating psychology of lying. Together they examine what we mean by lying, the line between a white lie and calculated manipulation, and what personality can reveal about how, and why, people deceive.

Drawing on the latest behavioural science, they also challenge the biggest myths around lie detection and uncover what research actually says about spotting a liar.
