Imposter syndrome is the persistent inner sense that your success is undeserved and that sooner or later you'll be exposed as a fraud. It shows up even when there's clear evidence of your competence, which is why researchers name it more precisely as the 'impostor phenomenon'. It was first described in 1978 by psychologists Pauline Clance and Suzanne Imes, who noticed it in high-achieving women who couldn't internalise their own accomplishments. It's now recognised as a very common experience across genders and fields, and — importantly — it tends to be unrelated to your actual ability.

This test is a 12-item educational self-report that places your everyday tendencies on a scale from few imposter feelings to an intense, pervasive pattern. It taps the facets the research describes: attributing success to luck, discounting praise, fear of being found out, comparing yourself unfavourably, and overworking to keep up appearances. Think of it as a quick mirror for noticing how loud the imposter voice is for you — useful for self-awareness, not a label that defines you.
