Imposter syndrome at work is the persistent feeling that you aren’t as capable as others think, and that you’ll be found out, despite evidence that you’re doing well. It is usually treated as a personal confidence issue, but it has a commercial cost: people over-prepare, avoid stretching themselves and stay quiet about ideas and risks, and it tends to grow, not shrink, with seniority.
Imposter syndrome is extremely common. Recruiter Hays surveyed more than 8,000 professionals and found that over 70 per cent of women and about 58 per cent of men had experienced it. KPMG’s 2020 research found that 75 per cent of female executives had felt it at some point in their careers.
This guide answers what imposter syndrome is, explains what it costs a business, shows how it flows down from the top of an organisation, and sets out three structural fixes that help whole teams, not just individuals.

What is imposter syndrome?
Imposter syndrome describes the gap between how capable someone is and how capable they feel. People experiencing it tend to put their success down to luck, timing or other people, and to see their mistakes as proof that they don’t belong. It isn’t a medical diagnosis, and it isn’t the same as low ability. In fact, it is common among high achievers, because each step up brings a new, bigger stage to feel exposed on.
The commercial cost of imposter syndrome at work
The cost shows up in time and in silence. A survey of 2,000 UK workers by the Executive Development Network found that people lose about ten days a year to imposter syndrome, mostly through over-preparing and perfectionism.
The less visible costs can be larger:
- Silence. People who doubt themselves don’t challenge bad ideas or flag risks early, so problems surface late.
- Missed stretch. Capable people hold back from bigger roles, new clients or difficult projects.
- Over-control. Some compensate by checking everything themselves, which slows teams and stops others developing.
- Turnover. People who never feel secure are easier to tempt away. To put a figure on a regrettable exit, try our employee turnover cost calculator.
How imposter syndrome flows down from the top
Imposter syndrome in the workplace isn’t just an individual issue, because leaders’ doubts shape the whole organisation. A CEO who feels like an imposter tends to respond in one of two ways. Some go quiet, avoiding big calls and hedging every message. Others overcompensate with certainty and control, which shuts down challenge.
The effects spread. Managers who doubt themselves may avoid hiring people better than they are. Company communications become vague, because nobody wants to commit to something they might be wrong about. Over time, a culture of quiet self-doubt sets in, where people are busy protecting themselves rather than doing their best work.
Three structural fixes for imposter syndrome at work
Coaching individuals helps, but the bigger gains come from changing the conditions that feed self-doubt. Three changes make the most difference.
1. Clear role metrics
People with imposter syndrome struggle to judge their own performance, so they look for outside reassurance. Give every role a few clear measures, so anyone can answer the question “did I have a good week?” for themselves. Clarity replaces guesswork, and confidence follows evidence.
2. Blameless post-mortems
If mistakes are punished or gossiped about, people who already fear being found out will hide them. Review projects without hunting for someone to blame, so mistakes become data points the whole team learns from. This also builds the kind of honest feedback and feedforward habits that help people grow.
3. Transparent progression criteria
When promotion feels like a mystery, people put their success down to luck or favouritism, which feeds the sense of being an imposter. Publish clear criteria for each level, so people can see they earned their place. Our guide to career development covers how to make progression more visible.
What leaders can do this month
Leaders set the tone, so small changes at the top go a long way:
- Talk about your own doubts. A leader who admits feeling out of their depth at times makes it normal for others to say so.
- Praise the process, not just the result. Recognise good thinking and honest challenge, not only wins.
- Ask for dissent directly. “What’s wrong with this plan?” gets a better answer than “any questions?”.
- Develop your managers. Many people promoted into management have never been trained for it, which is fertile ground for self-doubt. See our post on leadership and management development.
It also helps to hear from people anonymously, because those affected most are least likely to raise it in a meeting. Short, anonymous check-ins can show where confidence is low and where people feel unable to speak up. Wotter is one example of a tool built for that.
Exercise: the “good week” test
Ask each person in your team to write down, in one or two sentences, how they would know they’d had a good week at work. Then compare the answers with what you, as their manager, would say.
Where the answers match, people have the clarity they need. Where they don’t, or where someone can’t answer at all, you’ve found a gap that feeds self-doubt. Agree two or three clear measures for those roles within the month.
Frequently asked questions
What is imposter syndrome at work?
The persistent feeling that you are less capable than others believe and will be found out, even when the evidence shows you are doing well. It is common among high achievers.
How common is imposter syndrome?
Very common. Hays found that over 70 per cent of women and about 58 per cent of men had experienced it, and KPMG found 75 per cent of female executives had.
What does imposter syndrome cost a business?
The Executive Development Network estimates about ten days a year per person, mainly through over-preparing. It also costs through silence, missed opportunities and staff turnover.
How can employers reduce imposter syndrome?
Give every role clear measures, review mistakes without blame, publish transparent progression criteria and encourage leaders to talk openly about their own doubts.
Does imposter syndrome get worse with seniority?
It often does, because each step up brings bigger responsibility and more visibility, which can make people feel more exposed.
Make confidence a by-product of clarity
Imposter syndrome at work is common, costly and largely invisible. You can’t talk people out of it, but you can build an environment where they can see their own progress, learn from mistakes without fear, and know exactly what it takes to move up. Clarity does more for confidence than any pep talk.
