Impostor Syndrome in Women: Understanding & Overcoming It

You were offered the role. Deputy Director. Your first reaction wasn't joy, or pride. Your first reaction was a thought, sharp as a blade: "They're going to find out."

Find out what, exactly? You're not sure. But the certainty sits there, lodged in your sternum — that you don't belong at this table. That someone made a mistake. That you were hired for the wrong reasons, promoted by accident, selected for want of anyone better. And that when the truth comes out, it will be humiliating.

This isn't modesty. It isn't caution. It's impostor syndrome — and it affects brilliant, capable, rigorous people at every level of seniority.

According to research published in the International Journal of Behavioral Science, approximately 70% of people will experience at least one episode of impostor syndrome during their lives. And the evidence consistently shows that women — particularly in sectors where they are underrepresented — are affected with greater intensity and frequency.

A 2020 study by KPMG found that 75% of female executives across industries have experienced impostor syndrome in their careers. Research from BPP University found women are nearly twice as likely as men to experience it in professional settings.

This article explores the mechanisms of impostor syndrome, why it is gendered, and — most importantly — what you can do, concretely, to stop letting it dictate your professional choices.

What is impostor syndrome?

The term was coined in 1978 by two American clinical psychologists, Pauline Rose Clance and Suzanne Imes, in a landmark paper published in Psychotherapy: Theory, Research and Practice. They had initially described it in high-achieving women — university professors, executives, researchers — who, despite objective evidence of their competence, persistently believed themselves to be less capable than their peers believed them to be.

Impostor syndrome is not a mental disorder as defined by the DSM-5. It is a psychological pattern: a set of cognitions, emotions, and behaviours characterised by a persistent fear of being "found out" as a fraud or incompetent, despite demonstrable achievements.

The three core components

The work of Clance and Imes, refined by subsequent researchers, identifies three recurring dimensions:

1. External attribution of successes: "I succeeded because I was lucky, because the questions were easy, because the panel was lenient." Personal competence is systematically discounted as an explanation.
2. Internal attribution of failures: conversely, every mistake, every difficulty, is experienced as definitive proof of incompetence. The double standard is constant.
3. Fear of discovery: a sense of imminence — the conviction that sooner or later, someone will see "the reality". This fear generates a permanent, exhausting vigilance.

The paradox of achievement

One of the most disorienting features of impostor syndrome: it often intensifies at moments of success. Each promotion, each piece of recognition may increase anxiety rather than dispel it. The internal logic is relentless: "The more I succeed, the more there is to lose when they discover the truth."

This is not ingratitude. It is a well-documented psychological mechanism — and one that can be addressed.

The 5 impostor types: Valerie Young's framework

American researcher and author Valerie Young refined the Clance and Imes theory in her book The Secret Thoughts of Successful Women (2011). She proposes a taxonomy of five profiles, each with its own defence mechanisms and its own traps.

1. The Perfectionist

Perfectionism is the most common form — and the hardest to identify, because it is so often valorised as a professional quality. The Perfectionist sets standards so high that they are structurally unattainable. Every result below 100% is experienced as a failure, further proof that she isn't good enough.

Hallmarks: rereading an email ten times before sending. Submitting a report late because it isn't "quite right yet". Extreme difficulty delegating because no one will do it "well enough".

2. The Expert

The Expert never feels sufficiently qualified. Before applying for a role, she must master all ten listed competencies — and the three that aren't mentioned. Before speaking in a meeting, she must have verified every source. Before accepting a brief, she must obtain an additional certification.

Hallmarks: accumulating degrees, training courses and certifications without ever feeling "sufficiently" legitimate to act. Hedging every opinion with qualifications: "This probably isn't relevant, but…"

3. The Natural Genius

This type judges worth by the ease of learning. If something requires effort, repetition or time, that is evidence of insufficient talent. Genuinely capable people, in this schema, grasp things immediately.

Hallmarks: abandoning domains quickly where excellence doesn't come immediately. Becoming discouraged by a normal learning curve. Avoiding unfamiliar situations to avoid looking incompetent.

4. The Soloist

The Soloist believes that asking for help signals weakness. A true professional should be able to manage everything alone. Accepting mentorship, coaching or even a simple piece of advice calls into question her intrinsic competence.

Hallmarks: systematically declining offers of help. Working extra hours to avoid asking. Experiencing collaboration as a threat rather than a resource.

5. The Superwoman/Superman

This is perhaps the most exhausting profile: compensating for the sense of illegitimacy by working harder than everyone else. First in, last out. Refusing no assignment. Available around the clock. Volume of work must compensate for the absence of "real" competence.

Hallmarks: frequent burnout, inability to set limits, hypertrophied professional identity at the expense of everything else.

Why women are disproportionately affected

Clance and Imes initially described the phenomenon exclusively in women. Later studies showed that men are also susceptible — but converging evidence indicates that women experience the syndrome with greater intensity and in a broader range of contexts. Understanding why prevents us from reducing the problem to a simple lack of individual confidence.

Differentiated socialisation from childhood

Girls are more often praised for being "kind", "diligent", "well-behaved" — relational and conformist qualities. Boys are more often praised for being "brave", "strong", "bold" — qualities linked to action and risk-taking. These early messages create durable patterns: women learn to doubt before acting; men learn to act before doubting.

A 2019 meta-analysis of 20 studies across 12 countries confirmed that these socialisation differences have measurable effects on professional confidence well beyond adolescence.

Stereotype threat

Claude Steele and Joshua Aronson documented in 1995 the concept of stereotype threat: the mere awareness of belonging to a group associated with a negative stereotype is sufficient to impair performance in that domain. Women in male-dominated sectors — tech, finance, surgery, law — carry this additional cognitive weight during every professional interaction.

This is not fragility. It is a documented physiological response to a real social pressure. The British KPMG study (2020) found that for 81% of the female executives surveyed, imposter feelings were triggered by being in environments where they are in the minority.

The representation deficit

You cannot identify with what you cannot see. When a woman enters a board meeting composed 80% of men, she has no immediate model against which to normalise her presence. The absence of representation reinforces the feeling of being "out of place" — of occupying a seat not designed for someone like her.

According to the Hampton-Alexander Review's final report on FTSE 350 leadership, while the 33% target for women on boards has been broadly met, women remain significantly underrepresented at executive committee level — the decision-making layer that shapes organisational culture day to day.

The double bind of the woman leader

Women who assert themselves professionally face a well-documented double bind: to be perceived as competent, one must adopt behaviours typically attributed to men (assertiveness, taking up space, directness). But these same behaviours are socially sanctioned in women, who are perceived as "aggressive", "difficult" or "bossy".

This double constraint — be competent but not too ambitious, assert yourself but remain gentle — generates a permanent hypervigilance that is exhausting and feeds the sense of imposture. British workplace culture, with its emphasis on understatement and not "showing off", adds an additional layer: the cultural pressure to downplay achievement can make it even harder to own one's successes.

The minority tax

Women in male-dominated environments carry an invisible load: representing their gender in every public intervention, mentoring other women "because there's no one else", sitting on DEI committees in addition to normal responsibilities. This unrewarded overload erodes the energy available for developing one's own trajectory — and reinforces the feeling of never doing enough.

The real workplace impact

Impostor syndrome is not an abstract emotion. It translates into observable behaviours that directly impede career progression — and which are often invisible to managers and HR departments.

Not applying

The most widely cited statistic on this comes from an internal Hewlett-Packard study, referenced by Sheryl Sandberg in Lean In (2013): women only apply for a position when they believe they meet 100% of the listed criteria, compared to 60% for men. This figure has since been debated — but independent studies confirm similar patterns. A 2019 LinkedIn survey of 1.5 million users found that women send 20% fewer proactive applications than men for equivalent roles.

Every application not sent because "I don't quite have all the skills yet" is a career decision directly impacted by impostor syndrome.

Chronic over-preparation

To compensate for the fear of being found out, many women over-prepare everything: every meeting, every presentation, every interview. The result is a disproportionate expenditure of energy compared to male colleagues — and a structural exhaustion that leaves fewer resources for long-term strategic work.

Deflecting and minimising praise

"Oh, it was such a great team effort." "I got lucky with the timing." "Anyone would have done the same." These formulas are not false modesty. They reflect a genuine conviction that success does not belong to oneself. And they carry a real cost: they prevent the construction of a professional reputation commensurate with actual contributions.

Avoiding visible risk

Proposing a new idea in a meeting, speaking up in front of senior leadership, accepting a high-visibility project — these are precisely the situations that expose one to others' scrutiny and therefore to the risk of being "discovered". Impostor syndrome drives avoidance of these visibility moments — the very ones that build careers.

Burnout from overwork as proof

The conviction of not being legitimate pushes women to work harder than others to prove their value — not in terms of results, but in terms of visible effort and presence. This compensation logic is directly linked to burnout. The KPMG study (2020) found that 74% of female executives have kept quiet about moments of self-doubt, suggesting the burden is largely carried in silence, compounding the exhaustion.

It's not all in your head: the systemic dimension

There is a genuine tension in the impostor syndrome literature. On one side, the individual psychological dimension is real and requires personal work. On the other, framing the problem as exclusively individual is an analytical mistake — and sometimes a political one.

When doubt is rational

In some environments, women have good reasons to doubt their reception. Recruitment biases, pay gaps (women in the UK earn on average 14.3% less than men in full-time work, according to the 2023 ONS Gender Pay Gap figures), meeting dynamics where women are interrupted more frequently — these are real, documented realities.

Distinguishing impostor syndrome (distorted beliefs about one's own worth) from a clear-eyed reading of an environment that is actually discriminatory is crucial. Both coexist, frequently, in the same person in the same context.

The confidence instruction fallacy

The message "be more confident and everything will work out" is dangerous when addressed to women in organisations that are actually creating obstacles for them. Confidence does not make recruitment bias disappear. It does not dissolve glass ceilings or the meeting dynamics that structurally favour men.

Working on one's own cognitive patterns is a legitimate personal strategy. It is not a systemic solution. Both need to exist simultaneously.

What to do in a genuinely toxic environment

If you work in an environment that systematically invalidates women's contributions, where promotions do not reward equivalent female performance, where your impostor feelings are fed not by cognitive bias but by actual experiences of discrimination — the solution is not to work on your confidence. The solution is to change environment, or to take the issue to a collective level.

6 concrete strategies for overcoming impostor syndrome

The strategies that follow are grounded in cognitive and behavioural psychology literature. They do not claim to solve the problem at a stroke. They offer practical tools that can be tested this week.

1. The evidence file (success journal)

Impostor syndrome relies on selective memory: you retain mistakes and forget successes. The simplest counter-measure — and one of the most effective documented in CBT — is keeping a written record of your achievements.

Practically: a document (notebook, note, file) where you log regularly (at minimum once a week):

• One thing you did well this week
• A compliment received (word for word, without relativising it)
• A problem you solved
• A moment when you helped someone effectively

This is not vague self-help. It is building an empirical database your brain can access during moments of doubt. When the automatic thought says "you're not competent", the file says "in October, you delivered that project two weeks early and the client sent you this email."

2. Reframe: "I'm learning" rather than "I'm faking"

One of the most documented cognitive interventions in addressing the syndrome involves reframing the interpretation of gaps. The question is not: "Do I deserve to be here?" but: "What does this situation require me to learn?"

No one arrives in a new role with mastery of everything. Temporary incompetence is inherent to all progression. The difference between someone who suffers from impostor syndrome and someone who doesn't is not the actual competence level — it is the interpretation given to the learning zone.

3. Distinguish mentor from sponsor

A mentor advises you, guides you, helps you think. A sponsor acts for you — they cite you in meetings, recommend you for projects, advocate for your promotion. Women often have access to mentorship but not to sponsorship. Yet it is sponsors who make careers.

Concrete strategy: identify a person of influence in your organisation (or sector) who has observed your work closely. Propose a regular working relationship. Communicate clearly about your ambitions. Sponsorship does not fall from the sky — it is built through visibility and clarity of purpose.

4. Talk about it — normalise

Impostor syndrome thrives in silence and isolation. Every person experiencing it believes they are the only one. The simple conversation with a trusted colleague — "Do you ever feel like you don't quite belong here?" — can be destabilising in the best way: it reveals that the experience is near-universal.

Peer groups, women's professional circles, collective mentoring programmes can create these spaces of normalisation. Research shows that disclosing one's doubts to trusted individuals significantly reduces the intensity of the syndrome (Clance & O'Toole, 1987).

5. Strategic visibility

One of the most common errors is believing that work well done will speak for itself. It won't. Or rather: it speaks to those who have learned to make it noticed. Visibility does not mean boasting — it means ensuring your contributions are known to those who matter.

Practical tools:

• Sending a brief summary email to your manager after a successful project
• Mentioning your contribution (not just the team's) in team updates
• Publishing professional reflections on LinkedIn — not to show off, but to exist in your sector's conversation
• Asking to be included in cross-functional, high-visibility projects

6. Set "good enough" thresholds

Pathological perfectionism has no defined endpoint. The counter-strategy is to define, before beginning a task, what "done well enough" means in this context. Not "perfect". Not "beyond reproach". Sufficient for the objective at hand.

This sounds trivial. In practice, it radically transforms the relationship with work for Perfectionist or Expert types: they have a clear stopping criterion, and they can reach it.

When to seek professional help

Individual strategies have their limits. When impostor syndrome is deep-seated, anchored since childhood, or linked to traumatic experiences (discrimination, harassment, public humiliation), professional support is often necessary.

CBT (Cognitive Behavioural Therapy)

This is the best-evidenced approach for dysfunctional cognitive patterns. CBT works directly on identifying automatic thoughts, challenging them (cognitive disputation), and replacing them with more adaptive cognitions. Several controlled studies demonstrate its efficacy on impostor syndrome.

In the UK, CBT is available through the NHS via IAPT (Improving Access to Psychological Therapies) services for low to moderate anxiety and self-esteem issues. Waiting times vary considerably by region; private therapists typically charge £60–£120 per session. A course of 10 to 20 sessions with a CBT-trained therapist is often sufficient to significantly modify the most disabling patterns.

Schema therapy

For people whose syndrome is rooted in early schemas (relationship to parental validation, negative school experiences, family messages about personal worth), Jeffrey Young's schema therapy offers a deeper framework. It works on core beliefs — not just situational thoughts.

Professional coaching

Coaching is not therapy. It is goal-oriented, action-focused and present-tense. A well-qualified coach (ICF, EMCC accredited) can help you identify your patterns in specific professional situations and develop alternative behaviours. It does not replace therapy when roots are deep, but it effectively complements ongoing therapeutic work.

Finding the right support:

• Verify the training and accreditation of your therapist or coach
• Ask explicitly during a first session whether the professional has experience with impostor syndrome
• Be attentive to whether the support acknowledges the structural dimension (not simply "work on your confidence")
• Check EAP (Employee Assistance Programme) options through your employer — many UK organisations provide free confidential counselling sessions as part of employee benefits

For managers: reducing impostor syndrome in your team

If you manage women (or people from minority groups in your sector), be aware that your management behaviour can considerably amplify or reduce impostor syndrome in your team.

What amplifies the syndrome

• Imprecise feedback: a vague response ("that was good") does not counterbalance a specific criticism. Brains in impostor mode retain the mistake and forget the vague compliment.
• Public criticism: social humiliation in front of peers triggers intense stress responses that reinforce the conviction of incompetence.
• Ambiguous attribution of successes: when team successes are celebrated collectively without individual contributions being named, people in impostor mode do not internalise their role in the achievement.
• Comparison: anything resembling "why aren't you more like X?" reinforces the feeling of not being good enough.

What reduces the syndrome

• Precise, attributive feedback: "The risk analysis you did in section 3 — that's exactly what convinced the committee." Naming the specific contribution prevents the brain from attributing it to chance.
• Active visibility: citing your team members' work in your emails upward, in team meetings, in project reviews. Do not assume that strong performance is noticed of its own accord.
• Normalising the learning curve: saying explicitly, when assigning a new responsibility: "You're going to go through a phase of discomfort. That's normal and expected. It says nothing about your competence."
• Sharing your own uncertainties: managers who share (judiciously) their own moments of doubt create a culture where uncertainty is normal, not dangerous.
• Offering stretch assignments with a safety net: actively encouraging your team members to go for ambitious projects, and telling them explicitly that you will support them even if they don't get it right first time.

Frequently asked questions

Is impostor syndrome a mental illness?

No. Impostor syndrome is not listed as a disorder in the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders) or the WHO's ICD-11. It is a psychological pattern — a set of recurring cognitions, emotions and behaviours. It can coexist with anxiety disorders or depression, but it is distinct from them. It does not necessarily require therapeutic intervention — individual management strategies suffice in many cases — but therapy may be indicated when the syndrome is intense and deeply rooted.

Do men experience impostor syndrome too?

Yes. More recent research than Clance and Imes's original work shows that men are also susceptible — including in sectors where they are in the majority. However, several comparative studies indicate that women experience it with greater intensity, in a wider range of contexts, and with a stronger behavioural impact on career decisions. Socialisation factors and structural biases account in large part for this difference in intensity. The KPMG study (2020) of female executives found that many specifically attributed their impostor experiences to being "the only woman in the room" or belonging to other underrepresented groups.

Can impostor syndrome disappear completely?

For some people, with significant therapeutic or personal development work, the patterns attenuate considerably. For others, they remain present at a low level but become manageable — one learns to recognise them and not allow them to dictate important behaviours. The realistic objective is not the complete absence of doubt (a degree of doubt is healthy and functional) but rather to stop letting these doubts block important decisions. The Confidence Code by Katty Kay and Claire Shipman offers further practical frameworks for this shift.

How do I distinguish healthy humility from impostor syndrome?

Healthy humility coexists with a lucid awareness of one's genuine strengths. It allows for growth, acceptance of feedback, and acknowledgement of gaps without drama. Impostor syndrome, by contrast, produces a systematic distortion: evidence of competence is rejected or minimised; evidence of incompetence is amplified. A practical test: ask yourself whether you can accept a compliment without immediately deflecting it. If "thank you, I'm pleased with that presentation" feels impossible without adding "but I could have done better on part X" — the syndrome is probably at work.

What if my workplace is actively feeding my impostor syndrome?

First step: distinguish between what stems from your cognitive pattern and what reflects an actual organisational reality. If your manager regularly invalidates your contributions, if women in your team are systematically less promoted at equivalent performance, if your ideas are taken up without attribution — you have both a cognitive schema problem AND a real structural problem. Both warrant a response. For the organisational dimension: document incidents, consult HR or a union representative, build internal allies, and honestly assess whether this environment is compatible with your development. If it is not, planning an exit is a healthy decision, not a defeat.

Are there sectors where impostor syndrome is more prevalent?

Yes. Studies show higher prevalence in male-dominated sectors (tech, finance, engineering, commercial law, surgery), in highly competitive environments (elite universities, consulting firms, startups), and during career transitions (first management roles, sector change, return after a career break). "First" individuals in a role — first female director, first woman on a committee — are particularly exposed due to the combination of representation deficit and visibility pressure. UK research from BPP University specifically identified female professionals in finance and professional services as among the most affected groups.
