Imposter syndrome: why capable people feel like frauds
Imposter syndrome is the persistent, private sense that you are not as capable as people think, that your success is down to luck or charm rather than ability, and that you will eventually be found out. It is a described experience, not a medical diagnosis, and it is strikingly common: a 2020 systematic review of 62 studies found prevalence estimates ranging from 9 to 82 per cent depending on how it was measured.1 It tends to track with how much you care, not how little you know, which is why it clusters among capable, conscientious people. It is also loosenable.
Key facts
- The term comes from psychologists Pauline Clance and Suzanne Imes in 1978, who described it in high-achieving women who could not internalise their accomplishments.2
- It is not a clinical diagnosis: it does not appear in the DSM-5 or ICD-11, and researchers prefer the term "impostor phenomenon" to "syndrome".3
- A 2020 review of 62 studies and 14,161 people found it is common in both men and women, across ages, and frequently sits alongside anxiety and depression.1
- It is most strongly linked to perfectionistic concerns, the fear of falling short and of others noticing, rather than to healthy striving.4
- Higher self-compassion is reliably associated with milder impostor feelings, and is a plausible lever for loosening them.5
Where the idea came from
In 1978, clinical psychologists Pauline Rose Clance and Suzanne Imes published a paper in Psychotherapy: Theory, Research & Practice describing a pattern in high-achieving women: despite degrees, prizes and promotions, they remained convinced they were not really bright and had somehow fooled everyone.2 They called it the impostor phenomenon. The label has since broadened well beyond that original sample; the 2020 review by Dena Bravata and colleagues found it in men and women, students and senior professionals, across many countries and occupations.1
One point matters before anything else: this is an experience, not a disorder. It is absent from both the DSM-5 and ICD-11, and academics deliberately favour "phenomenon" over "syndrome" to avoid implying a medical condition.3 That is not dismissive. It means the feeling is real and worth addressing without being a sign that something is wrong with you.
How common is it, really
Honesty about the numbers matters, because inflated statistics are part of the problem. The often-quoted claim that 70 per cent of people feel like impostors traces to an unpublished survey, not a peer-reviewed study.3 The best synthesis we have, the Bravata review, reported prevalence anywhere from 9 to 82 per cent, the wide spread driven mostly by which questionnaire and cut-off each study used.1 The takeaway is not a precise figure but a direction: impostor feelings are widespread and ordinary, including among people you would never suspect.
If you feel this way, you are not unusually fragile or uniquely fraudulent. You are experiencing something a large share of capable people experience, often the ones who care most about doing well.
The impostor cycle
What keeps the feeling alive is a self-reinforcing loop, first mapped by Clance and elaborated by later reviewers.6 An achievement-related task triggers self-doubt and anxiety, and people respond in one of two ways that look opposite but lead to the same place.
| Response to the task | What it looks like | How success gets explained away |
|---|---|---|
| Over-preparation | Excessive effort, perfectionism, working far beyond what the task needs | "I only did well because I worked myself into the ground" (credited to effort, not ability) |
| Procrastination | Delay, then a last-minute frantic scramble to finish | "I just got lucky this time, I scraped through" (credited to luck) |
Either way the person succeeds, feels brief relief, then discounts the win. Because the success was never credited to genuine competence, it cannot bank as evidence. The next task arrives, the doubt returns, and the cycle repeats.6 This is why more achievement does not cure it: the loop is built to reject the very proof that would settle it.
The links with perfectionism and anxiety
Impostor feelings rarely travel alone. The strongest companion is perfectionism, but the type matters. Research distinguishes perfectionistic strivings (setting high standards) from perfectionistic concerns (fear of mistakes, doubts about actions, dread of others' judgment). A 2025 meta-analysis by Andrew Hill at York St John University and John Gotwals, pooling 25 studies and 12,141 people, found impostor feelings correlate strongly with perfectionistic concerns (r about 0.61) but only weakly with strivings (r about 0.15).4 In other words, it is not having high standards that hurts, it is the fear of being exposed for not meeting them.
The Bravata review also found impostor feelings frequently coexist with anxiety and depression, and are linked to burnout and lower job satisfaction.1 These relationships are mostly correlational, so we cannot say impostor feelings cause low mood, but the overlap is consistent enough to take seriously. If this resonates, our pieces on constant worry and the inner critic cover neighbouring ground.
How solid is this? The prevalence and comorbidity findings come from a large systematic review, though its studies are heterogeneous and mostly cross-sectional.1 The perfectionism link is meta-analytic and robust.4 The Bravata team found no trials of treatments specifically for impostor feelings, so the strategies below are reasoned from related, well-evidenced approaches rather than head-to-head impostor trials. Read them as sensible, low-risk and worth trying, not as proven cures.
Evidence-informed ways to loosen it
You do not need to feel confident to act competently. The aim is not to banish the feeling but to stop it steering you. A few approaches have logic and adjacent evidence behind them.
- Reattribution. The cycle survives by crediting success to luck or effort and failure to ability. Deliberately reverse this: when something goes well, name the skill, judgment or preparation that made it happen. Writing it down helps it register.
- Say it out loud. Clance and Imes noticed that simply naming the experience to trusted others, and finding how widely it is shared, reduced its grip.2 Secrecy feeds the sense of being a lone fraud.
- Collect competence evidence. Keep a running file of positive feedback and finished work. Impostor thinking discards data, so a concrete record gives you something to read when doubt overrides memory.
- Self-compassion. Treating yourself as you would a struggling friend is consistently linked with milder impostor feelings.5 Counter to intuition, in controlled experiments it increases motivation to improve rather than breeding complacency.7
- Drop the perfection bar to "good enough". Because the harm sits in perfectionistic concerns, practising finishing things to a sensible standard, rather than an impossible one, directly targets the engine.4

When it is worth getting help
Impostor feelings on their own are common and very workable with self-help. It is worth seeking professional support when they come with low mood, anxiety or hopelessness lasting more than a couple of weeks, when they are driving burnout, or when they hold you back from work, study or relationships you want. These states are common and genuinely treatable, and asking for help is a strength, not a confirmation of inadequacy.

You deserve support, and it helps to talk to someone.
What to ask your GP
- I feel like a fraud despite doing well, and it is affecting my mood: could this be linked to anxiety or depression?
- Can I be referred for talking therapy, or self-refer to NHS Talking Therapies?
- Are cognitive behavioural or compassion-focused approaches available locally?
- If low mood or anxiety has lasted several weeks, what assessment makes sense for me?
