You don’t need to feel confident before you start. You just need to start.

If you’re a new graduate sitting at your desk, staring at your first real assignment, wondering whether you’re doing it right or whether you even belong there, that feeling has a name. It also has a solution, and it isn’t waiting until the doubt goes away. According to research grounded in Acceptance and Commitment Therapy (ACT), the doubt may never fully leave, and that’s not a problem you need to solve before taking action. Starting tasks at a new job while unsure is not a sign of incompetence. It’s a sign you’re paying attention.

What Is Imposter Syndrome, Really?

Imposter syndrome isn’t a personality flaw or a mental health condition. It’s a pattern of thinking where you attribute your success to luck rather than skill, and you live in fear that others will eventually “find you out.” Research shows approximately 70% of people experience imposter syndrome at some point in their career, according to a 2007 article by journalist John Gravois in the Chronicle of Higher Education.

For new employees, the numbers are even sharper. The LinkedIn Workplace Learning Report (2023) found that 58% of employees report experiencing imposter syndrome during their first year at a new job. So if you feel unsure whether you’re doing this right, you are statistically in the majority.

In Lean In: Women, Work, and the Will to Lead (2013), Sheryl Sandberg captured the internal spiral precisely:

“We internalize the criticism. We question whether we are truly competent. We wonder if we truly belong.”

The cruel irony is that the people most prone to imposter syndrome are often the most conscientious, the ones who care the most about doing good work. First job self doubt isn’t proof you’re failing. It’s often proof you’re taking the work seriously.

Why Does Starting Tasks Feel So Hard When You’re Unsure?

When you don’t know if you’re doing something correctly, your brain treats ambiguity as threat. It wants resolution before commitment. So you wait for more information, more feedback, more reassurance, and the task sits untouched while the anxiety grows.

This is a cognitive trap, not a rational strategy. Psychologist Russ Harris, in ACT Made Simple (2009), identifies the mechanism clearly:

“The goal of ACT is not to eliminate difficult thoughts and feelings, but to change our relationship with them so they have less impact on our actions.”

The key word there is “actions.” ACT doesn’t promise to make the doubt disappear. It teaches you to act despite it.

New employees take an average of 8 months to reach full productivity, according to a BambooHR Onboarding Study (2019). That ramp-up period exists precisely because learning requires doing imperfectly first. Waiting until you feel certain before starting a task doesn’t protect you from mistakes. It just delays the learning that would eventually build real competence.

How ACT Principles Help You Act Despite Doubt

ACT, or Acceptance and Commitment Therapy, is a psychological framework developed by Steven Hayes in the 1980s. It has since accumulated substantial clinical research and has been adapted widely into workplace and performance psychology. Its core insight for new employees is direct: you can hold a thought like “I don’t know if I’m doing this right” without letting that thought make your decisions for you.

Harris, paraphrasing the broader ACT model in The Happiness Trap (2007), makes this point clearly. Our minds are incredibly good at generating predictions about the future and judgments about ourselves, but these thoughts are often just stories, not facts.

That reframe matters enormously for imposter syndrome new employee experiences. The thought “I’m not qualified enough to do this” is not evidence. It’s a cognitive event, like weather passing through. You don’t have to argue with it or eliminate it. You just don’t have to obey it.

In practice, ACT for workplace self-doubt involves three moves:

Should You Ever Wait Before Starting?

This is worth complicating slightly, because not all hesitation is avoidance.

In Originals: How Non-Conformists Move the World (2016), Adam Grant observes that people who wait to act until they have more information sometimes make smarter decisions than those who rush in before they’re ready. Strategic pausing has its place.

The distinction worth making is between gathering genuinely useful information and waiting for a feeling of certainty that won’t arrive on its own. Asking your manager one clarifying question before starting a task? Useful. Spending three days researching every possible approach because you’re afraid to commit? That’s first job self doubt driving the bus.

A reasonable rule: if one more piece of information would meaningfully change how you approach the task, get it. If you’re really just hoping the anxiety will subside, start anyway. Anxiety about performance rarely decreases before the task. It almost always decreases during or after it.

What “Doing It Right” Actually Looks Like for New Employees

Here’s a contrarian take worth sitting with: at your first job, doing it right and doing it imperfectly are often the same thing.

Organisations that onboard well don’t expect new graduates to perform at senior level within weeks. They expect engagement, effort, and a willingness to ask questions and iterate. The BambooHR Onboarding Study (2019) finding that full productivity takes around 8 months isn’t a failure benchmark. It’s a designed reality.

What managers actually notice in new employees isn’t perfection. They notice who gets stuck and says nothing versus who gets stuck, makes a start, and flags the uncertainty. Starting a task imperfectly and showing your working is more valuable than a polished product delivered after weeks of anxious delay.

The ACT framing here is useful again. When you’re unsure if you’re doing this right, the values-based question isn’t “am I certain enough to start?” It’s “what does someone who takes their development seriously do when they’re unsure?” The answer is almost always: they start, they document, they check in.

How to Actually Begin When the Doubt Is Loudest

Starting tasks at a new job when imposter syndrome is peaking requires a small process shift, not a confidence transplant.

First, shrink the task to its smallest possible starting unit. Don’t begin with “write the report.” Begin with “open a document and write one sentence about what this report needs to achieve.” Momentum is easier to build than to generate from nothing.

Second, make the uncertainty explicit rather than hiding it. A short message to your manager saying “I’m going to take a first pass at this and flag where I’ve made assumptions” is both honest and professional. It signals self-awareness, not incompetence.

Third, time-box the doubt. Give yourself a fixed window, say 20 minutes, to research or clarify, then commit to starting regardless of whether the uncertainty has resolved. The research on ACT-based behaviour change consistently shows that tolerating discomfort while acting is a trainable skill, not a fixed trait. You get better at it by practising it.

Fourth, remember that the LinkedIn Workplace Learning Report (2023) statistic cuts both ways. If 58% of new employees feel like impostors in their first year, then the person in the next desk almost certainly does too. The experience of imposter syndrome new employee cohorts share is not a secret failing. It’s a shared condition that most people are simply too afraid to name.

FAQ

Is imposter syndrome the same as lacking confidence?

Not exactly. Imposter syndrome specifically involves attributing your success to luck or deception rather than ability, and fearing exposure. Low confidence is a more general state. You can have reasonable confidence in some areas and still experience imposter syndrome in others, particularly when starting something new.

How long does first job self doubt usually last?

There’s no fixed timeline, but research context is helpful. Given that new employees take an average of 8 months to reach full productivity (BambooHR Onboarding Study, 2019), acute self-doubt often tracks closely with that adjustment period. For many people, it eases significantly once they accumulate concrete evidence of their own competence through completed work.

What should I do if I start a task and genuinely don’t know how to proceed?

Start with what you do know, document where you’re uncertain, and bring a specific question rather than a general one to your manager. “I’ve drafted the first section and I’m unsure whether you want me to include X” is more productive than “I don’t know how to do this.” It shows initiative and pinpoints where support is actually needed.

Can ACT principles really help with workplace anxiety?

ACT has a strong evidence base in clinical and applied psychology. Its core principle, that you can act according to your values while holding difficult thoughts and feelings, is directly applicable to workplace situations like starting tasks at a new job while unsure. It doesn’t promise to eliminate anxiety, but it does give you a framework for not letting anxiety run your schedule.

Is it normal to feel like an imposter even if I did well in university?

Completely normal, and arguably more common in high achievers. The environment shift from academic success to professional uncertainty is jarring. University rewards knowing the right answer. Most workplaces reward figuring out ambiguous problems without a marking rubric. The skills transfer, but the feedback loop changes, and that gap is where imposter syndrome tends to take hold.
