You are doing well on the outside. The results are there, the responsibility keeps growing, and to everyone around you it looks like you have it handled. Then, quietly, the doubt arrives. You brush off the compliment, question whether you really earned it, and brace a little for the day someone finally sees through you. If that rings true, it can help to know that imposter feelings are not one single thing. They show up in a few recognisable patterns, and seeing which one tends to be yours is often the first loosening of its grip.
The framework most people find useful here comes from Dr Valerie Young, who built on the original 1978 research by psychologists Pauline Clance and Suzanne Imes. In her book The Secret Thoughts of Successful Women, Young described five distinct types of imposter syndrome, five different ways the same underlying fear tends to play out.
Before we go through them, one thing worth holding onto. These are not fixed categories, and they are certainly not diagnoses. You do not have to fit neatly into one, and most people recognise themselves in several, or find they shift from one to another depending on the situation. They are best understood as patterns of coping, the different routes the mind takes to try to manage self-doubt and stay ahead of feeling not good enough. And once you can see the pattern for what it is, you are in a far better position to respond to it differently.
The Perfectionist
For the Perfectionist, it is all about how something is done, and it has to be flawless. You can hit ninety-nine percent of the goal and still find your attention snagged on the one percent you missed. Any mistake, however small, lands as evidence of failure rather than as being human. Underneath sits the belief that your worth depends on getting everything exactly right, so the inner critic is never far away. It tends to show up as overworking, endless attention to tiny details, difficulty delegating, and a strange inability to enjoy your own achievements. I have written more about this one in the Perfectionist imposter.
The Expert
The Expert measures competence by how much they know, and the bar is always "everything". If there is a gap in your knowledge, it feels like proof of inadequacy rather than the normal state of being a person, so you get caught in the loop of just one more course, one more book, one more qualification before you will feel ready. It often looks like hesitating to speak up unless you are completely certain, holding back from applying for a role until you tick every single box, and a constant low-level pressure to keep up. There is more on this in the Expert imposter.
The Soloist
The Soloist believes they have to do it all on their own. Needing help does not register as normal, it registers as failure, and independence quietly becomes the measuring stick for whether you are any good. Asking for support feels like exposing a weakness, so you carry things alone that were never meant to be carried alone. It shows up as avoiding collaboration, not delegating, and rarely asking for feedback even when you are visibly overwhelmed. I go into it further in the Soloist imposter.
The Natural Genius
The Natural Genius expects to get things right first time, and to get them right easily. If something takes effort or a few attempts, that effort itself becomes the evidence that you are not really capable. People in this pattern often have a history of things coming fairly easily, so the first real struggle feels less like learning and more like being found out. It tends to look like feeling ashamed when something takes time, avoiding challenges where success is not guaranteed, and giving up quickly when you are not immediately good at something. More on it in the Natural Genius imposter.
The Superhuman
The Superhuman, sometimes called the Superperson, ties self-worth to how many roles they can juggle and how well. Being good enough means doing it all, across work, family, relationships, health, everything, and doing all of it to a high standard at once. The pressure is relentless because the moment one plate is spinning nicely, attention jumps to the one that is wobbling. It shows up as pushing through exhaustion, real difficulty saying no, and measuring your worth by sheer productivity across every area of life. There is more in the Superhuman imposter.

What they all have in common
Read those five back and you will notice something. However different they look on the surface, every one of them is trying to do the same job. Each pattern is an attempt to protect you from the same fear, the fear of being not good enough and having it exposed. The Perfectionist avoids failure by chasing flawlessness. The Expert tries to outrun doubt by knowing everything. The Soloist equates competence with going it alone. The Natural Genius reads struggle as inadequacy. The Superhuman ties worth to endless doing. Different strategies, one purpose.
That reframe matters, because it moves the question away from "which box am I?" and towards something more useful. These are not personality types to be stuck with. They are habits of coping, and habits can be understood and changed. It is also worth noticing that imposter feelings tend to show up precisely where you care most, around competence, connection, and contribution. They are rarely a sign that you are incapable. More often they are a sign that something matters to you.
How therapy helps loosen the grip
Therapy for imposter syndrome is not about eliminating self-doubt or arguing yourself into permanent confidence. It is about building a different relationship with the doubt so it no longer runs the show. In practice that means noticing which situations trigger your particular pattern, understanding the fear sitting underneath it, meeting that fear with some compassion rather than more criticism, and reconnecting with the values that make it worth showing up despite the discomfort. Different approaches pull different levers here. CBT helps make the unhelpful thinking visible and workable. ACT helps you move in line with your values while the doubt is still present. CFT softens the harsh inner voice that drives the overworking and the checking. And where the pattern is rooted in earlier experiences of criticism or shame, EMDR can help take the charge out of those memories. If you want the fuller picture, I have written separately about how therapy can help with imposter syndrome.
Common questions
Who came up with the five types? They were described by Dr Valerie Young in her book The Secret Thoughts of Successful Women, building on the original imposter phenomenon research by Pauline Clance and Suzanne Imes in 1978.
Can I be more than one type? Yes, and most people are. You might be a Perfectionist at work and a Soloist in personal projects, or move between patterns depending on what is at stake. They are fluid, not fixed.
Are these an official diagnosis? No. Imposter syndrome is not a formal diagnosis, and these types are not diagnostic categories. They are patterns widely used in therapy and coaching because they help people recognise what is going on. I have written more on that in is imposter syndrome a real problem if it's not a diagnosis?
Does it affect only high achievers, or only women? The early research focused on high-achieving women, but later studies show imposter feelings affect men and women in fairly equal measure. What tends to vary is the context, with competitive fields, minority status, and times of transition all raising the odds.

Recognise yourself in this?
If you recognise yourself in one or more of these patterns, you are not alone, and you do not have to keep managing it quietly. You are not broken, you are stuck in a pattern that makes complete sense, and stuck is something we can work with together.
I offer a free 15-minute phone consultation, a relaxed, no-pressure conversation about what is going on and whether working together might be a good fit.
