You got the promotion and earned the role, so why does it feel like everyone's about to find out you're not qualified?

That unsettling sensation isn't just nerves.

Research estimates that roughly 70% of people experience imposter syndrome at some point in their career, turning accomplishments into sources of anxiety rather than pride.

Imposter syndrome, clinically called the impostor phenomenon, is the inability to internalize your own success, combined with a persistent fear of being exposed as a fraud. The concept was introduced by psychologists Pauline Clance and Suzanne Imes, and it's far more widespread than most realize. Nearly two-thirds of employees express doubt related to work accomplishments or feel inadequate compared to colleagues.

Sufferers commonly feel like a fraud and constantly doubt their abilities, despite the syndrome affecting high-achieving people. The paradox is striking: the more you achieve, the more convinced you become that you've somehow fooled everyone around you. You got the promotion, passed the bar, earned the clearance, made partner, and some part of you is still waiting for someone to tap you on the shoulder and say there's been a mistake.

Although it's most prominent in new hires, trainers, managers, and supervisors may also experience these feelings when in an unfamiliar or new situation. Stepping into higher responsibilities often involves being confronted with unfamiliar tasks and scenarios at work, which can lead to uncertainty and feelings of imposterism.

Research has shown younger people to experience greater feelings of workplace fraudulence, with 86% of 18-34 year olds reporting feeling that they don't deserve their jobs. Even high-profile figures aren't immune. Three in five workers endure these thoughts, including many high-achieving people like actress Viola Davis, Supreme Court Justice Sonia Sotomayor, and former First Lady Michelle Obama.

The Real Cost to Mental Health

Research has consistently found that people who struggle with imposter syndrome are more likely to experience mental health issues including anxiety and depression. The consequences extend beyond fleeting self-doubt. Signs include feeling like you can't make mistakes and remain a valued team member, putting in long hours or taking on additional projects just to feel like you're a part of the team.

Impostor feelings can persist even when an individual consistently exceeds performance goals and earns the respect of their peers. That disconnect between objective reality and internal perception creates chronic stress that affects both professional performance and personal wellbeing.

It's Not Just Your Problem

Here's where the conversation shifts. While the responsibility for addressing imposter syndrome tends to be placed on an individual to fix, many are arguing that workplace environments bear much of the responsibility. Experts like Valerie Young have observed how non-inclusive environments play a major role in its development. When people feel like they belong, they feel more confident, while previous definitions failed to fully take into account the impact of external factors that can make workers feel like their voices are unwelcomed.

If you're part of an underrepresented group in your workplace or industry, you may feel extra pressure to perform due to unconscious bias, which can heighten feelings of not belonging and make you doubt your qualifications, even when you are perfectly capable.

Practical Steps Forward

The first thing that will help alleviate feelings of being an imposter is to talk to your colleagues. Chances are, they don't feel perfect either, and having a coworker to discuss insecurities and self-doubt at work will provide relief and support. Find someone you respect highly in the field and put yourself in a position to learn from them, sharing your feelings of impostor syndrome if you trust the person.

For managers, the path is equally clear. Give clear business expectations as soon as possible during the onboarding process and when assigning tasks to employees. Without these expectations, individuals may have doubt about their role and what they should be doing. Even small steps, like ensuring more inclusive meetings, can create a more healthy work culture, where workers feel more secure in asking questions and being heard.

Recognizing impostor syndrome is the first step toward dismantling it. Whether you're experiencing it yourself or noticing it in your team, understanding that it's common, addressable, and often rooted in workplace culture rather than personal inadequacy changes everything. You're not a fraud waiting to be discovered. You're competent, capable, and you belong exactly where you are.
