Imposter Syndrome at Work: What It Is and What Helps

You get the promotion, and the first feeling isn't pride. It is a quiet certainty that someone made a mistake, and that sooner or later everyone will notice. So you prepare twice as hard as anyone else for meetings, wave off compliments, and put the good result down to timing, a generous manager or a team that carried you.

That pattern has a name, and a lot of people recognize themselves in it. The name also gets stretched to cover almost any self-doubt at work, which makes it less useful. This guide sets out what imposter syndrome means, where the idea came from, how it shows up on the job, and what actually helps, both for the person feeling it and for the managers and HR teams around them.

Imposter syndrome definition

Imposter syndrome is the persistent feeling that your success is undeserved and that you will eventually be exposed as a fraud, despite clear evidence that you are competent. People who experience it tend to credit their achievements to outside factors such as luck, charm, timing or other people's mistakes, while treating any slip as proof of what they suspected all along.

Three points help pin it down:

• It is about evidence being ignored. Ordinary nerves before a new challenge are not the same thing. The imposter pattern is when the record says you are capable and you still can't believe it.
• It is usually tied to achievement. It tends to flare when success becomes visible: a promotion, a new role, a public win, a move into a room full of people who seem more senior.
• It is not a diagnosis. A systematic review of the research notes that it is not a recognized psychiatric disorder and appears in neither the DSM nor the ICD-10. It describes an experience, not a condition a clinician diagnoses.

The original researchers called it the "impostor phenomenon." The word "syndrome" came later and stuck, though it makes the experience sound more medical than it is. You'll see both spellings, imposter and impostor.

Where the idea came from

The term goes back to a 1978 paper by two psychologists, Pauline Rose Clance and Suzanne Imes, titled "The Impostor Phenomenon in High Achieving Women: Dynamics and Therapeutic Intervention." Drawing on women they saw in therapy and in classes they taught, they described a belief that kept recurring: despite degrees, honors and promotions, these women were convinced they were not really capable and had somehow fooled everyone around them.

Because the first descriptions came from women, the experience was long assumed to be mainly a women's issue. Later research complicated that. The same systematic review, which pulled together 62 studies covering 14,161 participants, found the evidence on gender mixed: 16 studies found women reported more imposter feelings than men, while 17 found no difference.

The framing has drawn criticism too. A widely shared Harvard Business Review essay by Ruchika Tulshyan and Jodi-Ann Burey argued that labeling women, and particularly women of color, with "imposter syndrome" puts the problem inside their heads, when their self-doubt is often a reasonable response to workplaces where bias and exclusion are real. That critique matters for managers, and it comes up again below.

How imposter syndrome shows up at work

It rarely sounds like someone saying "I feel like a fraud." It looks like behavior that is easy to mistake for diligence, modesty or even weak performance.

What you might see	What can sit underneath it
Over-preparing for routine meetings, rewriting the same document again and again	Fear that one weak moment will give them away
Putting a task off, then finishing it in a last-minute rush	Dread of being judged, then relief at having "gotten away with it" again
Waving off praise, or crediting the team for solo work	Discomfort with evidence that contradicts their self-image
Not applying for a promotion or a stretch project	A belief they aren't ready, even when others clearly think they are
Staying quiet in meetings, not asking questions	Worry that a question will reveal what they don't know
Refusing to delegate, working late to check everything	A sense that only perfect work is safe
Anxiety that rises after a success rather than before it	More visibility feels like more to lose

The costs are real even when the work is good. Studies in the systematic review linked imposter feelings at work to less career planning, lower job satisfaction and more emotional exhaustion, which is one of the core parts of burnout. People who feel like frauds tend to work harder to avoid being found out, and that pace is hard to sustain.

A note on the numbers you'll see quoted. Articles often claim that most people feel like an imposter at some point. The research doesn't support a single figure. Across the studies in that review, prevalence ranged from 9% to 82%, largely depending on which questionnaire was used and where the cut-off was set. That spread says more about how hard this is to measure than about how common it is.

Why there's no imposter syndrome test on this site

We run several self-checks here, but none for imposter syndrome, and that is a deliberate choice.

The best-known questionnaire, the Clance Impostor Phenomenon Scale, is a copyrighted research tool, and its author asks that anyone using it on a website or for professional purposes get permission first. Her own materials say that a result is not an official diagnosis. The bigger problem is how unstable the scores are as a verdict. Studies use different cut-offs, and the review describes one group of people who came out at 24% or 39% depending on whether the line was drawn at a score of 62 or 58. It also flags that the scales may not be valid for ethnic minority groups, because of who was included when they were developed.

So any score we gave you would look far more precise than it is. The checkups we do offer use established screening questionnaires for problems that often travel with imposter feelings, and they are better places to start if you are worried about how you are doing: the GAD-7 anxiety checkup and the PHQ-9 checkup for low mood. Those are screening tools too, not diagnoses, but they have widely used scoring and a clear next step.

If you would rather reflect than score, these questions are more useful than a number:

• When something goes well, what do I credit it to? And when something goes badly?
• What would I say about this track record if it belonged to a colleague?
• Is there specific evidence that I'm not up to this, or only a feeling?
• Is the doubt about my skills, or about whether I belong here?

The last question is worth sitting with. Doubt about skills can often be answered with information and practice. Doubt about belonging may point to something in the environment rather than in you.

When it overlaps with anxiety or depression

Imposter feelings are not a mental health condition, but they often keep company with ones that are. The systematic review found imposter scores associated with depression, anxiety and low self-esteem. That doesn't mean one causes the other. It does mean a "confidence problem" can sometimes be the most visible part of something bigger.

Signs it may be more than imposter feelings:

• The worry isn't confined to work. It follows you into most areas of life, or you can't switch it off at night. The National Institute of Mental Health's overview of anxiety disorders describes what that can look like.
• Your mood has been low for weeks, you've lost interest in things you used to enjoy, or you feel hopeless.
• You're having panic attacks, or physical symptoms such as a racing heart, stomach trouble or poor sleep have become routine.
• You're drinking more, or using other substances, to get through the week.
• You're exhausted in a way that rest doesn't fix.

If any of that sounds familiar, talk to a doctor, a licensed counselor or your employee assistance program (EAP). You don't need to arrive with a label. "I keep feeling like I'm about to be found out, and it's affecting my sleep" is a perfectly good opening. If you are having thoughts of suicide or of harming yourself, call or text 988, the Suicide & Crisis Lifeline, any time in the US.

One point from my years as a benefits consultant: many employees assume the EAP is only for emergencies or for "real" problems. Short-term counseling for work stress, self-doubt and career pressure is exactly what most EAPs are set up to provide. It is free to use, it is confidential, and you don't need a diagnosis to call.

How to deal with imposter syndrome yourself

It is worth being honest about the evidence first. The systematic review found no published studies that had tested treatments for imposter syndrome itself. What follows are practical approaches that many people and practitioners use, not established fixes.

• Keep an evidence file. Save specific feedback, results and thank-you notes as they arrive, with dates. Feelings argue loudly, and a written record is harder to dismiss on a bad day. It is handy at review time anyway.
• Separate the feeling from the facts. When the thought "I'm going to be found out" arrives, write it down, then write what you actually know. This is the basic move behind cognitive approaches to self-criticism, and it works better on paper than in your head.
• Say it to someone you trust. Imposter feelings feed on the belief that everyone else is sure of themselves. A peer or mentor who admits they have felt the same is often the quickest correction.
• Right-size the effort. Over-preparing feels like protection, but it teaches you that success only comes from overwork. Set a stopping point for routine tasks and notice that the outcome is fine.
• Accept praise without editing it. Practice saying "thank you" and nothing else. No "it was mostly the team," no "I got lucky."
• Treat being new as a stage, not a verdict. Feeling out of your depth in the first months of a new role is normal. Being new at something is not the same as being bad at it.
• Be kinder to yourself on purpose. Self-compassion research looks at what happens when people respond to their own mistakes the way they would respond to a friend's. It isn't about lowering standards. It is about not punishing yourself for being human.

What helps if you manage people

Managers can make imposter feelings worse without meaning to, and they can do a great deal to ease them.

• Make feedback specific. "Great job" is easy to dismiss. "The way you structured that client summary meant we didn't need a second meeting" is evidence.
• Spell out what success looks like. Unclear expectations feed self-doubt, especially after a promotion. Say what good looks like in the first months, and what you don't expect yet.
• Notice over-functioning, not only under-performing. The person rewriting every slide at midnight may need a conversation as much as the one missing deadlines.
• Share your own learning curve. Hearing a senior person describe a time they felt out of their depth gives others permission to admit the same.
• Don't hand out the label. Telling someone "you've just got imposter syndrome" can feel dismissive, and it can hide real problems in the environment.
• Look at the environment honestly. Being the only woman, the only person of color or the only first-generation professional in the room is a different experience. Ask whether promotion criteria are clear, who gets stretch assignments and credit, and who gets interrupted in meetings. If the doubt has a cause at work, fix the cause.
• Point to support, then step back. Managers aren't counselors. Mention the EAP as an ordinary resource, not as a referral for a problem. Our guide to training managers to talk about mental health has wording that works.

HR teams can help at the level of systems: mentoring and sponsorship programs, transparent promotion criteria, onboarding that sets realistic expectations for new managers, and EAP materials that explicitly mention work stress and career worries, not only crises.

Two books for the inner critic and the people who lead

1. Self-Compassion: The Proven Power of Being Kind to Yourself by Kristin Neff

   The researcher behind self-compassion studies on how to treat yourself as you would a struggling colleague.

   Amazon page

2. Dare to Lead by Brené Brown

   Courage, trust and hard conversations for managers, from a researcher who studies vulnerability.

   Amazon page

Why these two: we chose them for the authors' credentials and expertise, publisher information and published reviews. Kristin Neff is a researcher whose studies helped establish self-compassion as an area of psychology, and her book speaks directly to the harsh self-judgment at the center of imposter feelings. Brené Brown is a researcher who studies courage, vulnerability and shame, and Dare to Lead (Amazon page) is written for people who manage others: giving clear feedback, having hard conversations and building trust. Neither is a substitute for professional help. For a wider list, see our roundup of mental health books worth reading.

Frequently asked questions

Is imposter syndrome a mental illness?

No. It isn't a diagnosis in the DSM or the ICD. It is a pattern of thinking and feeling that can be distressing, and it often overlaps with anxiety, depression and low self-esteem, which are worth checking with a professional.

Is it the same as low self-esteem?

They are related but not identical. Someone with low self-esteem may doubt themselves across the board. Imposter feelings are usually tied to achievement: the gap between what you have done and what you believe about yourself.

Can imposter syndrome lead to burnout?

Research has linked imposter feelings with emotional exhaustion, and the habits they encourage (over-preparing, overworking, not delegating) are hard to keep up. If you are running on empty, treat that as its own problem and raise it with your doctor or EAP.

Should I tell my manager?

That is your call. Some people find that naming the pattern ("I tend to second-guess my work after a big change") leads to clearer feedback and better support. You don't have to share anything about your mental health to ask for clearer expectations.
