In 1978, psychologists Pauline Clance and Suzanne Imes sat down with more than 150 high-achieving women — PhDs, executives, professionals with the credentials to prove their competence — and found something strange: nearly all of them privately believed they didn’t deserve to be there. They called it the imposter phenomenon. Today it goes by imposter syndrome, and it shows up just as often in the corner office as it does in someone’s first job.

What Imposter Syndrome Actually Is

Imposter syndrome isn’t ordinary self-doubt or a realistic read on a weak spot. It’s the persistent feeling that your accomplishments are the result of luck, timing, or fooling people — not skill — paired with the fear that someone will eventually “find out.” It shows up even in people with objectively strong track records, which is part of what makes it so disorienting: the evidence says one thing, the feeling insists on another.

Why Success Doesn’t Cure It

Most people assume imposter syndrome fades once you’ve proven yourself. In practice it often does the opposite — each promotion raises the stakes and the audience, which can make the fear of being found out louder, not quieter. Clance and Imes noted that high achievers tend to explain away evidence of their own competence (it was a fluke, they were just being nice) while treating any stumble as confirmation of the fear. That loop is what keeps the feeling running no matter how the rxc3xa9sumxc3xa9 fills out.

It’s More Common Near the Top, Not Less

Leadership roles tend to concentrate the exact conditions that trigger imposter syndrome: less feedback, higher visibility, and fewer peers to compare notes with. A first-time manager surrounded by people who’ve done the job for a decade, or a founder who is the only person who has ever held their title inside the company, has no easy benchmark for whether they’re doing it right — so the internal narrative fills the gap.

A Feeling, Not a Diagnosis

Despite the name, imposter syndrome isn’t a clinical condition and doesn’t appear in psychiatric diagnostic manuals. Clance herself pushed back on calling it a “syndrome” at all, preferring “phenomenon,” precisely because it describes a common experience rather than a disorder. That distinction matters: treating it as a normal, manageable feeling rather than a personal flaw is itself part of getting past it.

How Leaders Actually Overcome It

The fix isn’t waiting to feel confident before acting — confidence tends to follow competence, not the other way around. What helps is naming the feeling out loud to a trusted peer or mentor (almost everyone else is quietly carrying the same doubt), keeping a written record of concrete wins to counter the mind’s tendency to discount them, and separating the feeling from the facts: doubt is not evidence. None of that makes the feeling vanish. It just stops it from being the thing that decides what a leader does next.
