You've seen it, even if nobody called it by name. The analyst who rewrites a two-paragraph email four times before sending it. The new team lead who checks with you before every decision, including the ones they're clearly qualified to make. The high performer who answers "great work on this" with "I just got lucky with the timing."

That's imposter syndrome at work, and it's expensive. It slows decisions, is linked to burnout in your most conscientious people, and quietly stops talented employees from raising their hands for the next role.

Most advice on it is aimed at the person feeling it: affirmations, power poses, "own your success." This post is for the manager. Here's how to spot it, the seven things that actually help, and why reassurance alone almost never works.

What Is Imposter Syndrome at Work?

Imposter syndrome is the persistent belief that you're less capable than other people think you are, paired with a fear of being found out. People experiencing it tend to credit their success to luck, timing, or effort rather than ability, even when the evidence of their competence is strong.

Psychologists Pauline Clance and Suzanne Imes first described it in 1978 as the "impostor phenomenon." It isn't a clinical diagnosis, but it is well documented. A systematic review in the Journal of General Internal Medicine covering 62 studies and 14,161 participants found reported prevalence ranging from 9% to 82%, depending on how it was measured. The same review found it associated with impaired job performance, lower job satisfaction, and burnout. In other words, this isn't a private confidence issue. It shows up in the work.

Why It Spikes at Promotions

Imposter syndrome isn't evenly distributed across a career. It clusters around transitions: a new role, a new level, a new team. According to KPMG's survey of more than 700 executive women, 75% reported having personally experienced imposter syndrome, and 57% said they experienced it when they assumed a new leadership role.

Here's the uncomfortable part. For many new managers, the feeling isn't entirely irrational. They were promoted because they were excellent at a different job, then handed a team with no training in how to lead one. When a first-time manager says "I don't know what I'm doing," they're often giving you an accurate status report. Reassurance doesn't fix an accurate status report. Skill does.

That distinction matters for how you respond. Imposter syndrome is a gap between perceived and actual competence. You can close it from either side: by helping people see the competence they have, and by building the competence they're missing.

How to Spot Imposter Syndrome on Your Team

People rarely announce it. They compensate for it, and the compensation looks like diligence until it starts costing you. Watch for these patterns:

• Overpreparation for routine work: three drafts of a status update, a 20-slide deck for a 10-minute check-in.
• Deflecting praise every time, usually toward luck, the team, or "it wasn't that hard."
• Not asking for help, because asking feels like proof they don't belong.
• Turning down stretch work or volunteering only for tasks they've already mastered.
• Seeking constant sign-off on decisions within their own authority.
• Outsized reactions to small mistakes, where one typo becomes evidence of a deeper failing.

One pattern alone doesn't mean much. Several together, especially in a strong performer, usually do.

7 Things Managers Can Actually Do

1. Give specific feedback instead of general reassurance

"You're doing great" bounces off someone with imposter syndrome. They've already decided you're being kind or haven't noticed their flaws yet. Specific feedback is harder to dismiss because it's evidence, not opinion.

Instead of "great presentation," try "the way you handled the CFO's pricing question, with the two scenarios side by side, is what got the budget approved." Name the behavior, the impact, and the fact that it was a skill, not an accident.

• Tie praise to a specific action they took
• Point out the decision, not just the outcome
• Repeat the pattern when you see it again, so it becomes a known strength

2. Name the learning curve out loud

People with imposter syndrome tend to assume everyone else found the role easy. Telling them otherwise, with specifics, takes the shame out of struggling.

When someone takes on a new responsibility, say what normal looks like: "Most people take about six months to feel comfortable running budget reviews. If you feel shaky in month two, you're on schedule." Better still, share what you got wrong at the same stage.

3. Make asking for help a visible norm

If the only people who ask for help on your team are the junior ones, asking for help reads as a junior behavior. Change that by modeling it. Ask your team for input on problems you haven't solved. Say "I don't know, let's find out" in meetings.

Then reward it when they do it. A quick "glad you flagged that early" teaches more than any team charter about psychological safety.

4. Help them build an evidence file

Imposter syndrome feeds on selective memory. People remember every near miss and forget every win. A running record of what went well counters that with facts.

Suggest a simple habit: at the end of each month, write down three things that went well and what they did to make them happen. Review it together in your one-on-ones once a quarter. It doubles as raw material for performance reviews and promotion cases, which they'll probably undersell otherwise.

5. Assign stretch work with a safety net

Avoiding imposter syndrome by keeping people in their comfort zone backfires. They never collect the evidence that they can handle more. The goal is stretch with support, not stretch alone.

When you hand someone a project above their current level, agree up front on two checkpoints where you'll review progress together. That turns "I might fail publicly" into "I'll get feedback before anything goes wrong," which makes saying yes much easier.

6. Separate mistakes from identity

To someone with imposter syndrome, a mistake isn't an event. It's a verdict. How you talk about errors either reinforces that or breaks it.

Run reviews on the process, not the person: "What would we do differently next time?" rather than "Why did this happen?" Talk about your own mistakes in the same matter-of-fact tone. When failure is treated as information, people stop treating it as exposure.

7. Watch your own reactions

Managers rarely cause imposter syndrome, but they can feed it without noticing. A sigh at a question, a quick fix to someone's work without explanation, a public correction in a meeting: each confirms the story that they don't measure up.

• Correct in private, credit in public
• When you change someone's work, explain why, so it reads as coaching rather than a verdict
• Notice whose questions you answer patiently and whose you rush

When the Imposter Is You

If you're a newer manager reading this and recognizing yourself, you're in good company. The transition from doing the work to leading people who do it is one of the most disorienting in a career. Your old measures of success, like output, expertise, and being the one with the answer, no longer apply, and the new ones are slower and fuzzier.

The fix is the same one you'd offer your team. Collect evidence. Find someone who has made the transition and ask what their first year was actually like; a mentor is useful here, and our breakdown of coaching vs mentoring covers when each one helps. Most of all, build the skills that make the role feel less like guesswork: running a one-on-one, giving feedback, making a call with incomplete information. Confidence tends to follow competence, not the other way around.

One more thing. If the feeling is constant, affects your sleep or mood, or sits alongside persistent anxiety, that's worth raising with a doctor or your employee assistance program. The research links imposter feelings with depression and anxiety, and those deserve proper support, not just better management habits.

What HR Leaders Can Do About It

Imposter syndrome looks like an individual issue, but the conditions that create it are organizational. Promoting people into management without preparing them is one of the most reliable ways to produce it at scale.

• Train before or at the promotion, not a year after. The first 90 days set habits. Our first time manager training plan lays out what to cover and when.
• Give new managers practice, not just content. A manager who has rehearsed a hard conversation feels very different walking into the real one than a manager who watched a video about it.
• Teach managers to recognize it on their teams. The behaviors above are easy to mistake for perfectionism or low ambition.
• Watch who turns down promotions. Strong performers declining stretch roles is often a confidence signal, not a lack of interest.

Confidence Follows Competence

You can't talk someone out of imposter syndrome. You can help them build a track record that's too specific to argue with, and you can make sure they actually have the skills their role demands. Both come down to the same thing: real practice and real feedback, repeated until the new role feels like theirs.
