The Science of the Imposter Phenomenon: Named in 1978, Still Misread Today
The 'imposter phenomenon' was named in 1978 by two psychologists studying high-achieving women who, despite degrees, promotions and awards, remained convinced they had fooled everyone. Almost fifty years later, the research says three things clearly: imposter feelings are common in accomplished people of every gender, measured prevalence swings from 9% to 82% depending on which questionnaire you use, and success itself doesn't cure it — because the script discounts each new win as luck or charm. The newest work adds a twist: the feeling often tracks the environment, not just the person running it.
How the science changed · 1978–2021
- 1978
Pauline Rose Clance and Suzanne Imes name the 'impostor phenomenon' — an internal experience of intellectual phoniness — after clinical work with over 150 high-achieving women who, despite objective accomplishments, believed they had fooled anyone who thought them bright. ↗
- 1981
Joan Harvey builds the first questionnaire for the construct, the 14-item Harvey Impostor Phenomenon Scale — the start of a measurement tradition that would later produce widely divergent prevalence numbers. ↗
- 1985
Clance publishes the 20-item Clance Impostor Phenomenon Scale (CIPS) — still the most used measure — and describes the 'impostor cycle': anxiety before a task, over-preparation or procrastination, brief relief after success, then the success is discounted and the doubt returns intact. ↗
- 2011
Sakulku and Alexander's review consolidates the research: the impostor cycle, perfectionistic standards, fear of evaluation and discounting of praise form a coherent pattern — and it is documented well beyond the original sample of high-achieving women. ↗
- 2020
Bravata and colleagues publish the first systematic review — 62 studies, 14,161 participants: prevalence estimates range from 9% to 82% depending on the instrument and cutoff, imposter feelings are common in men and women alike and often co-occur with depression and anxiety, and not a single published study had evaluated a treatment. ↗
- 2020
Feenstra, Begeny, Ryan and colleagues publish 'Contextualizing the Impostor Syndrome': the person-based approach misses how social context — competitive climates, biased environments, lack of representation — shapes who ends up feeling like a fraud. ↗
- 2021
Tulshyan and Burey's Harvard Business Review essay 'Stop Telling Women They Have Imposter Syndrome' becomes one of HBR's most-read articles: the label, they argue, pathologizes individuals — especially women of color — for doubt that biased workplaces themselves produce. ↗
