Impostor syndrome is one of the most widespread phenomena among female talent in the IT industry, and at the same time, the least recognized for what it truly is: a belief, not a fact.
Women in tech experience it significantly more often than their male counterparts, with direct consequences in their career trajectory and workplace well-being.
Understanding what it is, why it especially affects women in tech environments and how it shows up day to day, is the first step toward managing it rigorously. This isn’t a self-esteem issue, it’s a documented cognitive pattern. Science has studied it broadly and it can be changed.

What is impostor syndrome and why does it matter in tech?
The term was coined in 1978 by psychologists Pauline Clance and Suzanne Imes after they observed a recurring pattern in high-achieving academic women. Despite their objective accomplishments, these professionals believed they didn’t deserve their success and that they’d gotten where they were by luck: someone would soon find it out.
Clance and Imes described it as an internal experience of intellectual fraud. Later studies showed it isn’t exclusive to women or to academia. Ther are conditions in the tech industry that amplify it: rapid change, a meritocratic culture, highly competitive environments and the underrepresentation of women in STEM leadership.
Studies published in the Journal of Vocational Behavior estimate that up to 70% of people will experience impostor syndrome at some point in their professional lives. However, its impact on career decisions varies significantly by gender, industry and work environment.
Impostor syndrome is not humility or modesty
Humility involves an accurate recognition of one’s own abilities. Impostor syndrome involves a systematic undervaluing of one’s own achievements that doesn’t match the objective evidence.
A person experiencing it doesn’t just underestimate one specific skill on occasion, they globally underestimate their right to hold the place they already hold. That distinction is key to identifying it and working through it.
The science behind the pattern
Cognitive neuroscience suggests that repeated self-critical thought patterns create neural pathways that make systematic self-doubt increasingly automatic and harder to question.
It isn’t a fixed personality trait, it’s a learned cognitive pattern.One that can therefore be unlearned with the right tools.

Why female talent in IT is especially vulnerable
Women in tech face an environment that amplifies the mechanisms sustaining impostor syndrome. Numerical underrepresentation, internalized gender stereotypes and the industry’s cultural patterns create a context where this phenomenon is more frequent, more intense and harder to question.
Underrepresentation as a risk factor
When a woman joins an engineering team where 80% of her colleagues are men, the environment sends signals — often unintentional ones — that this isn’t her natural space.
Social psychology has documented that simply being aware of being a minority activates cognitive vigilance mechanisms that consume mental resources and make it harder to perform at your full potential.
Women make up only 16% of ICT specialists in Spain (INE, 2026), according to the INE’s Labor Force Survey (technology occupations section). In leadership roles within the tech industry, that figure drops to 11.5% (Grant Thornton, 2026), the lowest percentage of any industry, according to Grant Thornton España’s Women and Business 2026 report.
Stereotype threat in STEM environments
The concept of stereotype threat, developed by Claude Steele and Joshua Aronson in 1995, describes a specific mechanism. When people from minority groups are aware of the negative stereotypes associated with their group, they can perform significantly worse on tasks related to that stereotype, even when their objective ability is equal to or higher than others’.
In the tech industry, the stereotype that women are “less technical” is widespread enough to trigger this mechanism. It isn’t a lack of preparation: it’s the mental cost of working while aware of the stereotype.
This effect is part of the gender gap in the tech industry and it impacts the career paths of female talent in IT from the earliest years of their careers.
The self-assessment gap: the number that explains it all
On average, women rate themselves 7 points lower than men in professional performance self-assessments on a 0-to-100 scale, despite identical objective performance (Bloom, 2026).
That gap doesn’t reflect a real difference in competence, it reflects a difference in the perception of that competence. The same logic explains why women tend to apply for a job only once they meet 100% of the requirements, while men apply at 60% or 70% (LinkedIn, 2021).
How impostor syndrome shows up in a tech career
Impostor syndrome doesn’t always show up as a paralyzing block. It often takes subtle forms that blend into everyday patterns and are hard to recognize precisely, because they seem reasonable.
In promotion and visibility decisions
One of the most well-documented manifestations is underparticipation in promotion processes: waiting for the perfect moment, putting off asking for a promotion until feeling “completely ready,” or not applying for a leadership role because of “a few years’ experience” are still missing.
Indeed’s data (2021) confirms this: 82% of men feel ready to ask for a promotion, compared to 70% of women in comparable settings. That 12-point gap doesn’t reflect a difference in readiness, it reflects a difference in the perception of that readiness.
In meetings, presentations and spaces of influence
Impostor syndrome also shows up in moments of visibility: cutting yourself off while speaking, adding hedging phrases, attributing successes to the team or holding back ideas out of fear they’re “not good enough.”
In technical environments, where authority and precision are highly valued, these behaviors directly affect how the environment perceives the competence of women tech professionals.
In salary negotiation
Women in tech negotiate their salaries less often than their male colleagues and when they do, they ask for smaller raises. A study published in Psychological Science directly links this difference to subjective self-worth perception, not to differences in objective productivity.

The real cost of impostor syndrome: for you and for your organization
Impostor syndrome isn’t a passing self-esteem issue. Its consequences are measurable: slower advancement, a greater tendency to leave the IT industry, less visibility in spaces where decisions are made, and a pay gap that widens over time.
Organizations pay that cost, too. They lose female talent with every promotion process someone opts out of, every application never submitted and every woman in STEM leadership who decides to leave the industry.
According to the report Women in the Workplace 2024 by McKinsey & LeanIn (McKinsey & LeanIn, 2024), companies with greater gender diversity in leadership are 21% more likely to outperform their competitors in profitability. Solving imposter syndrome is good for the women who suffer from it and for the organizations in which they work.
The first step is recognizing it for what it is
Impostor syndrome is persistent because it disguises itself as humility, intellectual rigor or professional caution. The first tool for managing a tech career is to recognize it as a belief: identifying the moments when it shows up so you can question whether it’s based on evidence or perception.
For professionals looking to strengthen their standing in STEM leadership, it’s vital to understand that this phenomenon disproportionately affects female talent in IT. Overcoming these cognitive biases isn’t just a matter of confidence, it’s a strategic decision to move toward higher-impact roles.
Bloom!, the book by Mariana Hernández-Delfino, devotes an entire section to impostor syndrome and other limiting beliefs that specifically affect female talent in IT. With more than 200 scientific references, it offers an evidence-based framework for moving forward without victimhood or empty formulas.

Frequently Asked Questions about impostor syndrome in Tech
Is impostor syndrome an official psychological diagnosis?
No. It isn’t included in the DSM-5 or the ICD-11 as a clinical diagnosis. It’s a cognitive and emotional pattern documented by psychology but it doesn’t constitute a mental disorder. Its relevance lies in the fact that it’s extremely common and has measurable effects on the professional behavior of women in tech.
Is impostor syndrome the same as low self-esteem?
Not exactly. Low self-esteem affects your overall sense of self-worth as a person. Impostor syndrome is more specific: it refers to the belief that you don’t deserve your own professional achievements, regardless of your self-esteem in other areas of life.
Do women experience impostor syndrome more than men?
Research shows nuanced results. The phenomenon isn’t exclusive to women, but there are significant differences in its impact on career decisions in tech. Women in male-dominated environments tend to experience it more intensely and make more decisions shaped by it.
Can impostor syndrome be overcome?
Yes. Since it’s a learned cognitive pattern, it can be changed using tools grounded in scientific evidence. Cognitive-behavioral therapy, working through limiting beliefs and developing self-awareness are all documented paths. The first step is recognizing it as a belief, not an objective fact about your competence.
How is impostor syndrome related to the gender gap in tech?
It’s one of the factors that perpetuates the gender gap in tech from within. When female talent in IT makes career decisions below their real potential — for example, avoiding leadership roles or not applying for a promotion — female representation statistics in STEM are directly affected. It isn’t the only cause, but it’s one of the most actionable from an individual standpoint.
