Imposter Syndrome
The persistent feeling that you're a fraud who has fooled everyone, despite real evidence of your competence.
Also known as: Impostor phenomenon, Impostor syndrome
Attributed to Pauline Clance and Suzanne Imes · Described as the "impostor phenomenon" in 1978
Imposter syndrome is the internal experience of believing you're not as capable as others think, and fearing being exposed as a fraud — even when there's clear evidence of your ability. First described as the "impostor phenomenon" by psychologists Pauline Clance and Suzanne Imes, it's extremely common, especially among high achievers.
What it is
Imposter syndrome is the nagging sense that your successes are down to luck, timing, or fooling people — and that sooner or later you'll be found out. Crucially, it persists despite real evidence of competence: qualifications, praise, results. The feeling doesn't match the facts.
The term traces back to psychologists Pauline Clance and Suzanne Imes, who described the "impostor phenomenon" in 1978 among high-achieving people who couldn't internalise their own accomplishments. It isn't a formal diagnosis or a mental illness — it's a common pattern of thinking and feeling.
Common signs:
- Attributing success to luck or external factors rather than your own ability.
- Fearing you'll be "exposed" as less capable than people think.
- Discounting praise and dwelling on mistakes.
- Feeling you have to work far harder than others just to keep up appearances.
A quiet irony: the feeling often shows up precisely in capable, conscientious people stretching into new or demanding roles. Genuinely incompetent people are, if anything, less likely to worry this way. Feeling like an imposter can be a sign you're growing, not proof you're a fraud.
Gentle ways to work with it:
- Name it. Recognising "this is imposter feeling, not fact" loosens its grip.
- Collect the evidence. Keep a note of what you've actually accomplished and the specific praise you've received, to counter the discounting.
- Talk about it. Hearing that respected peers feel the same is often a relief, and it normalises the experience.
- Reframe the fear with the same honesty you'd offer a friend who felt this way.
Imposter feelings are common and usually manageable with self-awareness. But if they cause significant distress, anxiety, or hold you back persistently, talking to a qualified professional can help.
Worked example
Newly promoted, Ffion is convinced she was chosen by mistake and will soon be found out — despite strong reviews and a track record that earned the role. When she starts noting the concrete reasons she was promoted, and hears that senior colleagues she admires felt the same early on, the "fraud" story begins to loosen.
