Impostor Syndrome Among High-Performing Executives: Understanding and Overcoming It

A promotion has just been announced. On paper, everything adds up: years of solid results, a supportive team, and projects successfully completed. Yet, in the mind of the person concerned, a little voice keeps nagging. «They’re going to eventually realize I’m not up to the task. » «I got lucky, yet again.» «The day they ask me the real question, I’ll be found out.»

Many experienced executives know this voice all too well. It doesn’t make a sound in meetings. It doesn’t show up on a resume. It works behind the scenes, in the evenings, when you find yourself rereading an email three times before sending it, or just before giving an important speech. It is the quiet face of imposter syndrome at work: that unsettling disconnect between objective success and the deep-seated feeling that you don’t deserve it.

What is often surprising is that this experience primarily affects competent, and sometimes brilliant, people. This is no coincidence. And the good news is that it is neither inevitable nor a character flaw, but rather a pattern of behavior that can be understood, observed, and then adapted. You don’t «cure» imposter syndrome: you learn to recognize it, to engage with it, and to regain control over how you interpret your own successes.

What the imposter syndrome really entails

The term has entered everyday language, sometimes to the point of becoming a convenient label for any moment of doubt. It is worth clarifying the matter more precisely.

Impostor syndrome describes a recurring pattern of thought: the person attributes their successes to external factors (luck, chance, help from others, a lenient jury) and their failures, even minor ones, to internal factors («this just proves I’m worthless»). Credit shifts outward, while blame always falls back on oneself. This imbalance creates a persistent belief: «If I succeed, it’s not because of me; therefore, I’m not really competent.»

It’s important to make this clear: this is not a disease, nor is it a clinical diagnosis. It is a set of widespread beliefs and psychological mechanisms that can be more or less pervasive depending on the stage of life. You might go through an intense phase when starting a new job, then see the symptoms subside, only to have them resurface when facing a new challenge. This variability is precisely what makes it so unsettling: you thought you had «resolved» the issue, and it comes back in through another door.

This article offers insights and food for thought. Coaching can help you come to terms with this experience and tap into your inner resources, but it is not a substitute for medical or psychological care. When doubt is accompanied by prolonged suffering, severe anxiety, or deep distress, diagnosis and clinical support are the responsibility of healthcare professionals and psychologists. Here, the focus is on prevention and mobilizing resources, never on treatment.

The cognitive mechanisms that drive it

To come to terms with what eludes us, we must first understand how it works. The feeling of being a fraud isn’t a reflection of your true worth: it’s the result of a few easily identifiable thought patterns that often go round in circles.

The selective filter applied to one's own successes

Our attention isn’t neutral. It filters. A person prone to imposter syndrome filters information in a very particular way: compliments slip by, evidence of competence is downplayed («it was easy,» «anyone could have done the same»), while the slightest mistake is highlighted in bold and underlined. Over time, the memory builds a case against them, carefully skewed.

In practical terms, imagine two columns. In the «evidence that I am legitimate» column, items are erased as they appear. In the «evidence that I am not» column, every entry remains permanently recorded. With such an accounting system, the verdict is a foregone conclusion, regardless of the actual facts.

Limiting beliefs and inner dialogue

Behind the feeling of being a fraud almost always lie deep-seated beliefs, often internalized at a very early age: «To be worthy, I must be flawless,» «Asking for help is admitting weakness,» «If I’m not the best, I’m nothing.» These statements are not facts. They are implicit rules we have imposed on ourselves, often without ever having consciously chosen them.

The role of a coach is precisely to bring these rules to light and then to question them. This is what we call reframing: changing the lens through which we view a situation, without denying reality. A simple example: shifting from «I asked a question in the meeting, so I showed that I didn’t know» to «I asked a question, so I helped clarify a point for the whole team.» Same facts, different interpretation. Reframing doesn’t gloss over reality: it opens up a more accurate and useful interpretation of it.

The self-perpetuating cycle

The most insidious aspect of this phenomenon is its ability to feed on itself. This is what’s known as a feedback loop: a system where the effect reinforces its own cause, like a microphone placed too close to a speaker that ends up producing an increasingly loud whistling sound.

Here’s how it goes. I doubt my own worth. To make up for it, I overdo things: I overwork, I double-check everything, I spend nights on a project. The result is excellent. But since I attribute it to my over-effort («I just made up for it»), it never builds my confidence. When the next success comes, I start all over again, convinced that without this relentless drive, everything would fall apart. The competence is definitely there, proven time and again, but the feeling of being a fraud just won’t go away. It has turned every success into proof that I have to keep running.

Understanding this cycle is the first step toward breaking it. After all, we can’t address what we don’t see, and we can rarely resist what we haven’t named.

Why are high achievers particularly vulnerable to this?

Herein lies the great paradox, and it’s worth pausing to consider. The feeling of being a fraud doesn’t strike the least competent people at random. It often targets those who do the most, who succeed the most, and who set the bar very high.

There are several reasons for this. The more a person progresses, the more they realize how much they still don’t know: competence opens one’s eyes to complexity, whereas inexperience can sometimes offer a false sense of security. Moreover, high-achievers readily compare themselves to the best in their field, not to the average. Measured by this standard, any success seems insufficient.

There is also a contextual factor at play. The higher one rises in the ranks, the more one finds oneself among highly competent individuals, and the more the perceived gap between oneself and others narrows—which can reinforce the misleading notion that «there is nothing exceptional about oneself.» Pivotal moments particularly highlight this experience: a promotion, a change of employer, or reaching a new level in the hierarchy. This is, in fact, one of the reasons why support during the transition into a new role often proves invaluable, allowing time to fully embrace one’s new position.

The special case of high-potential employees

Some people with unique cognitive styles experience this disconnect even more acutely. High-potential individuals, for example, often think in a branching manner: one idea leads to ten others, connections spring up, and nuances multiply. This is a true asset. But this way of thinking has a downside. Where others see a clear answer, these individuals perceive a dozen angles, exceptions, and «yes, buts.» This leads to a difficulty in feeling «certain» about anything, and creates particularly fertile ground for imposter syndrome.

Added to this is often a life marked by a sense of not quite fitting in: having long felt that you don’t think «like everyone else» can leave a lasting mark—the feeling that you never quite allow yourself to feel at home. Understanding that this uniqueness is also—and above all—a professional asset profoundly changes the relationship one has with it. On this specific point, the work conducted around the high potential and its specific characteristics in the workplace usefully sheds light on how cognitive intensity can be transformed into strength, rather than remaining a source of doubt.

Engage, don't fight: practical strategies

You can’t silence that feeling of being a fraud through sheer willpower, nor by repeating «I believe in myself» in front of the mirror. Confronting it head-on tends to make it stronger. The solution-focused approach offers something else: rather than trying to make it disappear, it focuses on changing the role it plays and how we perceive ourselves.

Rebalancing internal accounting

Since the selective filter erases evidence of legitimacy, the first step is to make that evidence visible again. This is the foundation of success: getting into the habit of recording, factually, what has been accomplished, how it was done, and what specific skills were used. Not to pat ourselves on the back, but to reconstruct an honest record where memory had deliberately kept a biased one.

A simple and effective exercise: after a success, ask yourself three questions. What did I actually do? Which decisions were mine to make? What was within my control and not just luck? The point is not to deny the role of circumstances or others, but to stop completely downplaying them. Little by little, the column of evidence of legitimacy stops emptying as it fills up.

Distinguishing between feelings and facts

Coming to terms with imposter syndrome also means learning to draw a line between «I feel unworthy» and «I am unworthy.» The first is an emotion, perfectly real and valid. The second is a statement about reality, which needs to be verified. Doubt is not reliable information about your worth: it is a feeling that says something about your standards, not your competence.

This realization is liberating. It allows you to keep moving forward even with doubt, rather than waiting for it to disappear before taking action. Because it may never disappear completely, and that’s okay. Many highly accomplished people move forward alongside their inner critic. They’ve simply stopped treating it like an oracle.

Building a Strong Foundation: Confidence and Self-Esteem

The feeling of being a fraud often stems from a distinction that people confuse: self-confidence («I feel capable of doing this») and self-esteem («I am valuable, no matter what I do»). A person can accumulate evidence of competence without necessarily boosting their self-esteem, because the latter is based on something other than performance. This is precisely why so many successes are never enough to quell doubt.

In-depth work on these two areas, such as that explored in the discussion on building confidence and self-esteem through support, ...helps to separate one's self-worth from one's results. This is often where lasting change takes place: not by achieving more in order to finally feel legitimate, but by ceasing to make one's legitimacy dependent on the next performance.

The value of an outside perspective

The imposter syndrome thrives in silence and secrecy. As long as it remains hidden inside, it retains its full power. Putting it into words, in front of someone trained to listen without judgment, takes away some of its hold. Support helps you identify your own patterns, explore alternative perspectives, and draw on your strengths rather than focusing on your shortcomings.

That is the whole point of a personalized one-on-one support : to create a space where one can set aside those thoughts usually kept to oneself, examine them without either complacency or harshness, and gradually rebuild a more accurate sense of one’s own worth. The coach does not hand out certainties; instead, they help the person rediscover their own—the ones that were always there, simply obscured by a filter.

When doubt becomes a driving force

It would be a shame to conclude by suggesting that all doubt should be eradicated. A certain kind of doubt is healthy: it fosters humility, a desire to learn, and attentiveness toward others. People who harbor a little doubt question themselves, learn, and listen. The problem is never doubt itself, but the doubt that paralyzes, that exhausts, that turns every success into a reprieve.

Coming to terms with imposter syndrome, then, does not mean striving for flawless, smooth, and unshakable confidence. It means learning to make that doubt a companion on the journey rather than a relentless judge. It means allowing yourself to take your place, not because you’ve finally found definitive proof of your legitimacy, but because you’ve realized you don’t need it to move forward.

This journey always begins with a more accurate understanding of oneself, one’s background, and one’s unique qualities—and in particular, how an intense or atypical way of functioning can, in a professional context, a real help in everyday life rather than a source of withdrawal. The feeling of being a fraud loses much of its power the day you stop fighting it and simply begin to understand it.
