TL;DR. Valerie Young sorted imposter feelings into five types, each built on a different private definition of what competence should look like: the Perfectionist, the Expert, the Natural Genius, the Soloist and the Superhero. This matters practically, because the standard advice fails each one in a different way. Telling a Perfectionist to celebrate their wins does nothing, and telling an Expert to learn more actively makes it worse. Below is a portrait of each type and the counter-move that fits it. The thing that helps across all five is the same and it is unglamorous: a written record of what actually happened, kept before you need it.
There is a specific evening that produces this feeling reliably.
You have shipped something. Nobody has said anything. The metrics are noise at this volume. There is no manager, no performance review, no colleague to compare notes with, and somewhere between closing the laptop and going to bed you arrive at the quiet conclusion that you have been getting away with it and someone will eventually notice.
I build a habit tracker alone, in the evenings, in public. It is an extremely efficient machine for producing that evening.
What follows is the part I found genuinely useful once I stopped reading the generic version.
What Clance and Imes actually described
The concept comes from a 1978 paper by the psychologists Pauline Clance and Suzanne Imes, based on their work with high-achieving women who were convinced their success was undeserved.
Two details from that work keep getting lost.
The first is the name. They called it the impostor phenomenon. Not a syndrome, not a disorder, and it has never been a diagnosis in any manual. The drift to the word syndrome happened in popular writing and it changed how people relate to it: a phenomenon is something you experience, a syndrome sounds like something you have.
The second is the mechanism, which is not low self-esteem. The people in that work generally performed well and were regarded well. The problem was the accounting. Success got attributed to luck, timing, charm, or working harder than anyone realised. Failure got attributed to the self. Evidence in your favour has nowhere to land, which is why reassurance bounces off.
Why the generic advice fails
The advice you find under the head term is roughly: recognise your achievements, be kinder to yourself, remember everyone feels this way.
None of it is wrong. All of it is aimed at nobody in particular.
Valerie Young's contribution, set out in her writing on competence types, was to notice that people are running different rules. Each type has its own definition of what a competent person would do, and each one breaks in a different place. Advice that ignores the rule you are running slides straight off.
The Perfectionist: if it is not flawless, it failed
You set the bar somewhere unreachable, then treat the gap as evidence of fraud. One critical note in a page of praise is the only line you reread. Work sits in draft long after other people would have shipped, because shipping means the flaws become visible.
Why the standard advice fails. Tell a Perfectionist to celebrate their wins and they will find something wrong with the win. The reflex you would need to interrupt is the same reflex being asked to do the celebrating.
The counter-move. Define done in writing before you start, then ship at that line whether or not it feels ready. A time box works better than a quality box, because your judgment of quality is the compromised instrument. The mental discipline is separating the standard for the work from the verdict on you.
The Expert: I need to know more first
You feel unqualified to speak until you have covered everything. You collect courses. You are the person who has read more about the topic than anyone in the room and will not say so, because you know exactly what you have not read.
Why the standard advice fails. The obvious suggestion, learn more, prepare better, is fuel. More preparation raises your sense of how much remains unknown, so the finish line moves every time you approach it.
The counter-move. Cap the preparation before you start: this much research, then I act. Then teach someone. Explaining a thing to a person who does not know it is the fastest way to discover how much you know, and it produces external evidence you cannot easily dismiss.
The Natural Genius: it should have come easily
You were the kid who found it easy, and you concluded that ease is what ability looks like. Now anything that takes three attempts feels like an exposure. You avoid whole categories of work where you would visibly be a beginner.
Why the standard advice fails. Just practise more reads as a confirmation of the fear rather than a solution to it. You already believe that needing practice is the problem.
The counter-move. Track attempts on purpose, and treat the count as neutral information about the task rather than a verdict on you. Write down how long the thing you are good at took to become easy. It will be longer than you remember, because you have edited that part out.
The Soloist: asking for help would prove it
Help does not count. If someone assisted, the achievement is contaminated. You will lose six hours to a problem a colleague could have unblocked in five minutes, and you will describe those six hours as diligence.
Why the standard advice fails. Believe in yourself is exactly the wrong instruction. It reinforces the rule that you are supposed to be sufficient on your own. It is also the type most likely to be quietly rewarded by managers, so nothing external corrects it.
The counter-move. Ask one small question a day, deliberately, on things that do not matter, until it stops feeling like an admission. Then count the cost honestly: hours lost, quality lost, deadlines moved. The Soloist does not respond to encouragement, but does respond to arithmetic.
The Superhero: excellent in every role, always
Work, parent, partner, friend, the side project, the fitness thing. Falling short in any one triggers the whole verdict, and busyness becomes the way you outrun it. Rest feels like exposure with extra steps.
Why the standard advice fails. Work on your confidence is received as another item on the list, and it will be done thoroughly and joylessly at 11pm.
The counter-move. Pick the three roles that get your full effort this season and consciously drop the standard on the rest. Not forever, for this season. Then schedule rest as a fixed commitment rather than as a reward for finishing, because there is no version of your week that ends in finished.
The founder version, honestly
Building something alone in public strips out every external correction.
There is no manager telling you the quarter went fine. Nobody signs off your work. Revenue at small numbers is genuinely noisy, so you can read any story you like into a slow week. I wrote about the wider version of this in building in public in a saturated niche: the honest problem is not competition, it is that you are the only one keeping score, and you are not a reliable scorer at 11pm.
My own two types, since I am asking you to name yours, are Perfectionist and Soloist. That combination has a specific failure mode: I will not ship it and I will not ask anyone about it. Recognising the pair was worth more than any amount of general reading, because it named the exact intersection where my weeks go missing.
The only thing that has reliably helped is embarrassingly plain. I keep a written record of what actually happened.
Keep the record before you need it
The reason a wins log works is mechanical rather than motivational. The feeling is not arguing with the facts, it is arguing with your memory, and your memory at 11pm on a bad Thursday has been curated by the same process that produced the feeling.
Four rules that make it work.
Write what happened, not how it felt. Shipped the export fix. Said no to the extra scope. A user emailed about the grid. Facts survive rereading. Feelings from three weeks ago do not.
Include the boring entries. The unremarkable ones are the point, because the pattern is what convinces, not any single line.
Timestamp it and never edit backwards. A record you tidy is a record you can talk yourself out of.
Reread it monthly, and on the bad evenings. That is the whole return on the habit.
I wrote the longer method up in the done list, and the daily wins journal is a free place to keep one that stays in your browser.
What the quiz does, and what it does not
The imposter syndrome quiz here runs thirty scenario questions. Each describes a familiar situation, a promotion, one critical note among ten compliments, being stuck for an hour, and offers five responses, one written from each type's logic. Your picks are tallied into a primary and a secondary type with the full distribution across all five, plus that type's typical triggers, the strengths underneath it, and a set of strategies. An Evidence Journal tab holds accomplishments, feedback and skills, and your history saves locally so you can retake it and see whether the distribution moved.
It is not a diagnostic instrument and I will not describe it as one. It measures which style of self-doubt you reach for in familiar situations, which is genuinely useful for choosing a counter-move and useless for anything else.
When it is not imposter syndrome
Two honest caveats.
Sometimes you actually are underqualified for the thing in front of you. That is not a distorted self-assessment, it is an accurate one, and the fix is skill and time rather than better self-talk. The distinguishing question is whether your track record contradicts the feeling. If it does not, you have a learning problem, which is a much better problem to have.
And sometimes the environment is producing it. A workplace where nobody is ever told they did well will manufacture this feeling in people who are doing fine. If the exhaustion has arrived alongside it, the signs of burnout is the more relevant read, and if it is persistent and touching your sleep, appetite or ability to work, that belongs with a professional rather than with a quiz.
Everything here is about a feeling, not a fact. The counter-moves are type-specific. The record is universal.

Written by Eusebiu, the solo founder building Loggd in public. I build it in the evenings around contract work and a small daughter, with nobody to tell me the quarter went fine, which is how I ended up keeping the log described above. I share what the aggregate data keeps showing on Threads.
Keep the evidence where you will actually see it. Loggd logs what you did each day and shows it as a contribution grid, so a quiet week reads as a quiet week rather than as proof of anything. Start free.
