At a glance
You are holding the evidence of your own competence and you still feel certain you have fooled everybody. The feeling survives every success because of what you do with the result in the moment it arrives. This article shows you that moment closely enough to interrupt it, and says where your workplace is doing some of the work.
Clinical insights from 22 years in psychotherapy
I’m Mark Colclough, MA, psychotherapist in Copenhagen. Qualified at the Psychosynthesis Education Trust and the University of East London. 22 years of full-time, face-to-face clinical practice.
- It arrives as a footnote. My clients rarely open with this. It surfaces halfway through a story about a promotion they wanted and got.
- The credit leaves the room in seconds. I stop the sentence at the point where my client hands the result to luck or to somebody else, because that one move is the whole pattern working in front of me.
- The rule is older than the job. Underneath it I find a private rule about what counts as proof, written long before the work my client is doing now.
Clinical notes: My observations are anonymised and compounded from my session notes since 2004.
What is imposter syndrome, and is it actually a diagnosis?
Imposter syndrome names an experience that no diagnostic manual recognises as a disorder1.
That changes how you hold it. You are not carrying a condition with a known course and a known treatment. You are carrying a way of handling your own results, learned somewhere, and open to being examined. Nobody has yet tested a treatment for it2, so be careful with anyone who offers you a method and a success rate.
- How common it is. Surveys put it anywhere between 9 and 82 per cent of those asked2, and the spread comes from the screening tools rather than from the people. A range that wide tells you the experience is ordinary and tells you nothing at all about yourself.
- Who reports it. Men and women both report it, from students to people near the end of long careers2. Seniority is no protection, and in my experience a promotion raises the feeling rather than settling it.
- What it is like from inside. You have the role and the good reviews, you leave the meeting certain you have got away with it again, and now there is further to fall.

Why does success not make the feeling go away?
Success settles nothing, because of what happens in the first minute after it lands.
What arrives with the good news is relief rather than pleasure, and relief is thin. It drains out within the hour. Your shoulders drop, you breathe out once, and something in you is already looking for the next test. Only then does the thinking start, and it runs one way: the brief was easy, the competition was weak, you worked absurd hours, they were being kind. A bad result takes the opposite route and goes straight inward, where it is read as information about your worth.
You want the work seen. At the same moment you keep a rule that refuses to let the recognition count, and both of those belong to you. Run that ledger for 10 years and the column marked evidence of competence is still empty, because nothing is ever admitted to it. Praise gets filed as politeness, or as proof that the person has not looked closely enough yet. Each success raises the stakes: a bigger reputation to be caught out with, and a longer drop. After enough years of this you can lose sight of who you are when you are not performing.
What happens when nothing short of complete mastery counts?
An all-or-nothing standard turns every ordinary gap in your knowledge into the moment of exposure.
There is no middle position to stand in. Either you are completely on top of this, or you have been lucky for a decade and the luck is about to run out. Nobody holds the first position for long, which leaves one place to go. In my clinical judgement this rule is the joint between perfectionism and the fraud feeling. Loosen it and an ordinary professional gap stops being proof of anything, and the feeling loses most of its evidence at once.
Where the rule came from matters less than how faithfully you still keep it. If being valued once depended on performing, then failing threatens belonging and not only competence. That is why a routine question in a meeting can land as a dropping sensation, heat in the face, the urge to be out of the room, long before you have thought anything at all. If that is familiar, the shape of anxious attachment and what your attachment style does under pressure are both worth reading. Some of my clients find the rule in an early relationship. Others find it in one job, one manager, one year.
Is it me, or is it the room I am in?
Part of this belongs to the room, and where you sit in a hierarchy changes how exposed you feel.
- The word syndrome does some of the damage. Calling it a syndrome implies a fault inside the person and leaves the setting unexamined3. The same argument points out that the groups the label attaches to most readily, women and members of ethnic minority groups, are the groups already carrying persistent negative stereotyping.
- Changing the setting is a proposal, not a finding. The suggestion that contextual change would prevent impostor feelings rather than only treat them is put forward for further research3, and it has not been tested.
- Arriving as the outsider. This is my clinical judgement rather than a research finding. New to a country, a company culture or a profession, you hold less context than everyone around you, and missing context gets read as missing ability.
- Working in a later language. A language you learned as an adult leaves you slower, less precise and less funny in meetings than you are in your first one. That gap is evidence about vocabulary, and it is worth deciding deliberately what language you want to do your own therapy in.
Telling the room apart from the rule is slow, and the answer is rarely all of one. What I will say is that if you have only ever examined yourself, half the material is still untouched.
How do you stop feeling like a fraud at work?
You change what you let yourself count as proof, and you do it in writing, because arguing with yourself has already failed.
What follows comes from my practice rather than from a tested protocol.
- Write the plain line. After anything that goes reasonably well, write one line: what you did, and what happened. Keep it up for 2 weeks, which is my suggestion and not a clinical threshold.
- Leave out the escape hatch. No explanation, no credit handed elsewhere. Notice how uncomfortable the bare line feels.
- Say it to one person. Choose somebody who will not rush to reassure you, because reassurance is the easiest thing in the world to discount.
- Watch the second after praise arrives. There is a move you make before you have decided anything. Watching it does more than correcting it.
- Use your own standard on somebody else. Ask what you would say about a colleague who had done exactly what you did.
- Read the room. Notice whether your workplace rewards certainty and punishes questions, because some workplaces manufacture this feeling efficiently and then describe it as a personal failing.
There are 3 situations where this is not enough. When the escape hatch goes back into the line every time you write it, the rule is holding firmly enough that it needs another person in the room. When the feeling sits inside months of exhaustion and nothing giving you pleasure, then in my judgement the standard of proof is a symptom of something wider rather than the cause of it. And when the workplace is hostile rather than demanding, changing what you count as proof will not change what is being done to you. Which of the 3 you are in is hard to see from inside, and that is a reasonable thing to bring to a first session.
Questions people ask
Is this worth bringing to therapy when work is otherwise going well?
Yes, when the feeling is costing you sleep, candour, or the ability to accept a role you have already earned. Many of my clients arrive about something else entirely and find this sitting underneath it.
What does the work actually involve?
I follow what you do with proof, using real examples from the past week, rather than listing your achievements back to you. The material that moves things is one sentence you said about a success, taken apart slowly.
Will I have to talk about my childhood?
Only as far as it explains the rule you are still applying at work today. If the rule turns out to be recent, that is where the work stays.
How do I choose a therapist for this?
Ask how they work with self-criticism and whether they will challenge what you say about your own successes. A therapist who only reassures you leaves you with more praise to discount.
What if I discount what the therapist says too?
You probably will at first, and that moment is the most useful thing in the session. It is the pattern happening where both of us are able to see it, which is the one place it becomes workable.
If you are waiting to be found out at work, I explore that fear with you in imposter syndrome therapy.
