Feeling Like a Fraud at a New Job? Why It Happens

Week two. In the team chat, people drop acronyms you've never seen. Someone writes "per the Q3 decision," and everyone replies with a thumbs-up. You add one too, then quietly search the term in another tab.

A thought slides in: "They're going to find out they hired the wrong person."

If you're feeling like a fraud at a new job, you have plenty of company. Psychologists have studied this feeling for decades. Here's what they've found, why new roles stir it up, and one small habit to try this Friday.

What impostor feelings are

In 1978, psychologists Pauline Clance and Suzanne Imes described high achievers who credited their success to luck, timing or other people (Clance & Imes, 1978). Many quietly feared being "found out." They called it the impostor phenomenon.

These feelings are common. A 2020 review of 62 studies found reported rates from 9% to 82%, depending on the group and how it was measured (Bravata et al., 2020). They show up often in people who are clearly doing well, including right after a new job or a promotion.

Why a new job turns the volume up

Not knowing is normal, but it feels like evidence

Every new role comes with a learning curve. You don't know the tools, the people or the unwritten rules yet. That's expected. But when you already doubt yourself, each "I don't know" can feel like proof.

You compare your inside to their outside

You see coworkers who seem relaxed and fluent. You don't see their first month, their own searches in another tab, or their doubts. You're comparing your messy inside to their polished outside.

Your stumbles feel louder than they are

Research on the spotlight effect suggests people overestimate how much others notice them. In one study, people wore an embarrassing T-shirt into a room (Gilovich et al., 2000). They guessed about twice as many others had noticed it as actually had. That awkward question you asked in the meeting? Likely forgotten by lunch.

The loop that keeps it going

Many people describe the same cycle:

A new task feels scary, so you over-prepare.
It goes fine.
You credit the extra prep, or luck, instead of your skill.
The next task feels just as scary, and the loop starts again.

Because each win gets explained away, your confidence never gets the evidence it needs. That's the part worth changing.

A surprising upside, and its limits

Research by Basima Tewfik at MIT looked at "workplace impostor thoughts" (Tewfik, 2022). In her studies, employees with more of these thoughts were rated by supervisors as more effective with colleagues. In experiments, people with these thoughts asked more questions, which helped others see them as more effective. She didn't find a cost to performance (Dizikes, 2022).

But Tewfik also notes the thoughts lowered self-esteem. So it's not something to cultivate. It does suggest that your doubt may come with real strengths: humility, curiosity and a habit of asking good questions.

Asking for help is easier than it feels

New hires often avoid asking, so they won't look clueless. Research suggests people say yes more than we expect.

In studies by Francis Flynn and Vanessa Lake, people asked strangers for small favors (Flynn & Lake, 2008). The askers overestimated by about 50% how many people they'd need to ask before someone agreed (Stanford Graduate School of Business, 2013). Direct asks also worked better than hints.

How you ask matters too. In a field study led by Ashley Whillans, asking reviewers for "advice" instead of "feedback" drew more concrete, useful input (Whillans et al., 2025). "What's one thing you'd advise me to try in my first month?" is easier to answer than "Any feedback?"

Which pattern might be underneath?

In Sabotype's language, impostor feelings lean toward the Understudy: capable of the lead role, but sure you're only filling in. If you also polish everything before anyone sees it, the Polisher may be in the mix. Most people lean toward one pattern at a time, and that can shift.

What the feeling protects, and the strength inside it

Feeling like a fraud can seem like pure downside. But it does a job. Crediting luck keeps expectations low, so a stumble later won't feel like being "found out." Staying quiet keeps you from being evaluated before you feel ready.

The trade-off is that your evidence never piles up. You keep doing good work, and none of it counts in your own mind.

The strengths underneath are real. People with this pattern tend to be humble, careful and easy to coach. They keep learning when others coast. You don't need to become loud or overconfident to step forward. You just need your own evidence to count.

One tool to try today: the Friday evidence log

This takes about 5 minutes, once a week. Open a note called "Evidence."

Every Friday, write three lines:

One thing I learned this week. "How the release process works."
One thing I did that helped someone. "Fixed the report link Sam needed."
One question I asked. Asking is part of the job, so it counts.

Then add one rule for next week: when someone praises you, say "Thank you" and stop. No "it was nothing," no "I got lucky."

The log turns vague progress into something you can see. The rule stops you from explaining your wins away before they land.

When to talk to a professional

Doubting yourself in a new role is very common. Consider talking to a doctor or a licensed mental health professional if self-doubt keeps you from things you want for months. The same goes if the pressure to prove yourself leaves you exhausted, or you feel low or hopeless for weeks. A primary care doctor can point you to the right person (National Institute of Mental Health, n.d.).

Questions people ask

Is it normal to feel like a fraud at a new job?

Yes, it's very common. A new role means a learning curve, and not knowing things is expected. When you already doubt yourself, that normal gap can feel like proof you don't belong.

How long do impostor feelings last at a new job?

There's no set timeline, and it varies a lot from person to person. Keeping a written record of what you've learned and done can make your progress easier to see.

Should I tell my manager I feel out of my depth?

You don't need to share the feeling itself. Asking specific questions and asking for advice on your first months is normal, and managers often expect it.

Are impostor feelings a diagnosis?

No. Impostor feelings aren't a diagnosis. Researchers call it the impostor phenomenon. The Understudy is our name for the everyday pattern.
