Impostor syndrome in women: what the research shows

Rachel is presenting the quarterly figures. Ten people are sitting at the table, she is the only woman, and she has been through the deck she wrote herself four times. When the director praises her in front of everyone, she hears herself reply that the brief was unusually clear.

Nobody in that room has ever wondered whether she belongs there. The question runs only in her head, and it has been running quietly for three years. Rachel would call it a confidence problem, because that is how the thing is usually sold. Except that explanation fits neither the data nor what actually happens in a room like that.

A description that started with successful women

The pattern was described in 1978 by the psychologists Pauline Clance and Suzanne Imes. They worked with students and with women from universities and companies, people who already had degrees, publications and promotions behind them. The same internal sentence kept coming back: they think I am better than I am, and one day somebody will work out how it really is.

The sample was female, and the label has been stuck to women ever since. The authors themselves later pointed out that a female sample says nothing about who the experience belongs to. The sample decided where the description was born, not who owns it.

The idea that this is a women's topic arrived before there was any data to test it against, and it then held on for another forty years mostly through repetition.

Do women really have it more often?

The broadest summary so far came in 2020, in a systematic review of 62 studies by Bravata and colleagues. Reported prevalence in them ran from 9 to 82 percent, depending on who was asked and what instrument was used. That spread is information in itself: something is being measured before researchers have agreed where exactly it starts.

On differences between the sexes the review gives a mixed picture. Some studies found higher scores in women, others found no difference at all. So the sentence "women suffer from it more" is not documented, and neither is the sentence that no difference exists.

The results diverge for several reasons. Studies differ in their samples, in the questionnaire used and in the cut-off above which a score counts as elevated. All of them rest on self-report, so part of any difference may sit in the willingness to write it down about yourself rather than in who lives with it.

One more number deserves caution, the one that circulates most often in writing on the subject: that roughly 70 percent of people know the feeling. It comes from a 2011 review by Sakulku and Alexander, and it is phrased there as an estimate rather than as a result of measurement.

The room sends signals about who belongs

A more useful question than the one about sex is the one about the room. In 1995 Claude Steele and Joshua Aronson described a mechanism now known as stereotype threat: when someone works on a demanding task in a setting where their group is assumed to do worse, part of their attention goes to monitoring that assumption, and performance drops. The original study involved students whose group carried such a stereotype; later work examined the same mechanism in other groups and situations.

The practical consequence is quiet. It is not that the person thinks something bad about themselves at that moment; a slice of capacity simply goes on watching how they come across, and watching is tiring.

Caution has an awkward property too: it confirms itself. Prepare three times over and you usually succeed, but the credit then goes to the preparation rather than to the ability. The worry never gets into a situation where it could be proved wrong, so the next comparable day starts with the same stock of doubt. Which is why the pattern does not shrink with promotion; if anything the opposite, since the higher you go, the more people around you look as though they are there by right.

On top of that comes the position of being the only one of your kind in the room. Whoever is the exception in a team is more visible, blends into the background less easily, and has a stumble read as evidence of something larger than one bad day. Higher visibility on its own produces more cautious behaviour: extra preparation, and silence until you are a hundred percent sure.

The clearest evidence that none of this is about being a woman is the reverse case. Daniel teaches at a preschool and is the only man among fourteen staff. He prepares for parents' evenings more than his colleagues, says less in team meetings than he could, and when a parent praises him he credits the whole team. Parents who do not know him occasionally ask him where the teacher is.

The link between a minority position and this kind of doubt was studied by Kevin Cokley and his team in 2013 among university students from minority groups: minority status stress was related to those feelings. What decides is not who is sitting in the room, but how many of them there are.

Why "women believe in themselves less" leads nowhere

The first problem is factual. If this were a stable trait it would travel with the person everywhere, and it does not. The same woman can stay quiet in one team and speak first in another without having done any work on herself in between. The doubt moves with the environment faster than character does.

The second problem is practical. If the cause is a shortage of confidence, the only available piece of advice is to believe in yourself more, and the whole job then sits with the person who has the least power to change the room. The company, the school or the team walk away without a task.

The word "syndrome" is worth a second look as well. It sounds like something a person has and can be cured of, while what it describes is a fairly ordinary way of interpreting your own results. The name moved the centre of gravity inside the person, which may be why advice on the topic so often stops at breathing exercises and affirmations while the composition of the room stays untouched.

And then there is a detail that disappears completely. Rachel does not think she is bad at her job; she knows she reads the numbers better than most people at that table. The doubt does not sit on her abilities. It sits between the result and its interpretation, in the question of who ends up being credited.

Three places where the doubt speaks up

The pattern splits into three sources. They are related, but they differ in where exactly they slot into your thinking. The piece on what impostor syndrome is takes them apart in detail; in short, they look like this.

Which of the three speaks loudest differs from person to person, and it does not track sex nearly as neatly as newspaper headlines suggest. What does show up reliably in a room where you are the exception is extra preparation and caution about speaking. Where all of that surfaces during an ordinary working week is covered by the separate piece on impostor syndrome at work.

Guessing your own source from the inside is hard, because each of them sounds like a plain description of reality rather than an opinion. A short impostor syndrome test gives an approximate picture: it asks about everyday situations and shows both the overall level of doubt and which source is strongest for you. Treat it as a starting point, not a diagnosis; this is not a disorder and it does not appear in the classifications of mental disorders.

What one person can do about it

Most of the usable things rest on one principle: a feeling cannot be argued away by another feeling, but notes on paper get further. Four of them take a couple of minutes a week.

• Before something demanding, write down your prediction of how it will go and why. Compare it with what happened. If it repeatedly turns out better than you expected, you are holding evidence that luck cannot explain away.
• Set a ceiling on preparation in advance and stop when it runs out. Preparation beyond that point no longer raises quality, it only quiets the uncertainty for a while.
• Answer praise with one word: thanks. No rider, no immediate redirection to the team.
• An unspoken doubt grows; a spoken one shrinks. Pick one person in your field and describe specifically what you are unsure about. Almost every time, it turns out they know the same thing from the inside.

When did you last let a compliment stand without adding anything to it? Not accepted politely, but genuinely left alone. If you cannot remember, you have a fairly precise reading of which source does the most work in your head.

Comparison deserves separate attention. In a room where you are the exception it is tempting to measure yourself against people whose beginnings you never saw, and the more usable yardstick is your own version from a year ago. Why somebody else's highlight reel always beats your own backstage is taken apart in the piece on comparing yourself to others.

What everyone else can do

General praise can be explained away in a second; specific praise is harder to dispose of. "Good job" evaporates without effect, while "you proposed recalculating the methodology and it saved us two days" has nowhere to run. For managers and colleagues it is the cheapest intervention available.

The second thing is visibility. A mentor talks to you about what to do, but the person who helps most is the one who says your name in a room you are not in. And where it is possible, do not leave someone as the only one of their kind; two people of the same kind at the table stop being representatives of a group and go back to being colleagues.

At home it is harder than at work, because the first reaction tends to be reassurance, and reassurance reliably fails. What to do instead is described in the piece on how to help someone with impostor syndrome.

One honest note at the end. When the doubt lasts for months, takes your sleep or keeps you away from opportunities you know you could handle, self-knowledge is not enough on its own and it is worth talking it through with a psychologist. That is not an admission of defeat, just a different tool for a different weight.

Before the next meeting Rachel wrote two sentences on a piece of paper: how she thought it would go, and why. It said they would ask about the methodology and she would falter. They asked about the methodology and she answered. She kept the paper, because in three months the sentence in her head will sound exactly the same, and it will be useful to have something on hand that disagrees with it.
