‘When are they going to discover that I am, in fact, a fraud, and take everything away from me?’
Tom Hanks, winner of two Oscars, four Golden Globes and six Emmys, interviewed in 2016

First coined in a 1978 research paper on high-achieving women in the workplace, the term ‘imposter syndrome’ describes those who believe they have less talent that others think, who attribute any personal successes to luck, and who worry that they’ll ultimately be exposed as the frauds they perceive themselves to be. This kind of reflexive self-doubt is not so much a ‘syndrome’ as it is a widespread state of psychological distortion, with roughly 70 per cent of people experiencing it at some point in their lives. In this video from BBC Ideas, Sandi Mann, a psychologist and lecturer at the University of Central Lancashire in the UK, discusses the roots of imposter syndrome and details some practical ways to fight it.
