What Impostor Syndrome Actually Is, and What Helps
It’s technically not a syndrome. Psychologists Pauline Clance and Suzanne Imes, who first documented it in a 1978 study of high-achieving women, deliberately called it the “impostor phenomenon,” not a syndrome or disorder, because it isn’t a diagnosable condition. It’s a persistent, internal experience of feeling like a fraud despite real, external evidence of competence, and later research showed it extends well beyond the group Clance and Imes originally studied.
What It Actually Is
The impostor phenomenon has a specific, recognizable shape: someone attributes their success to luck, timing, or other people’s error rather than their own ability, and lives with a quiet, persistent fear that they’ll eventually be “found out.” It’s not simple self-doubt, and it’s not humility. It shows up specifically alongside real, demonstrable achievement, which is exactly what makes it so persistent, the evidence contradicting the feeling never seems to convince the person experiencing it.
Why This Belongs on an HR Site, Not Just a Self-Help One
Most impostor phenomenon content is written entirely for the individual experiencing it. That’s useful, but it skips the employer’s role almost entirely, and workplace conditions genuinely make it worse or better.
- Vague, infrequent feedback makes it worse. When feedback only arrives at an annual review, an employee has months to privately catastrophize about their own performance with nothing concrete to check that feeling against.
- A hierarchical, high-power-distance culture can compound it. In workplace cultures where junior employees are less likely to question a senior colleague’s assessment or ask clarifying questions openly, someone experiencing impostor feelings has fewer natural moments to get the reassurance or context that would counter them.
- Rapid promotion without structured onboarding into the new role feeds it directly. Someone promoted quickly, common in fast-moving sectors with aggressive lateral hiring, often has real, current skill gaps for the new role’s specific demands, which can look and feel identical to impostor phenomenon even when it’s actually a legitimate, temporary transition gap. Telling them “you’ve got this” without real support conflates the two.
What Actually Helps, Individually
Track a written record, not a mental one
Memory is unreliable for this specifically, negative moments tend to stick disproportionately while genuine wins fade. A simple running log of concrete accomplishments and specific positive feedback, however small, gives you something to check the feeling against later, rather than relying on memory in the moment it matters most.
Ask for feedback more often than the formal cycle
Waiting for a scheduled review to find out how you’re actually doing leaves a lot of room for the gap to fill with anxiety instead of information. A short, specific question to a manager or trusted colleague, asked outside the formal review cycle, closes that gap faster than waiting does.
Separate “I don’t know this yet” from “I’m a fraud”
Not knowing something in a new or expanded role is a normal, expected, temporary state, not evidence of being fundamentally unqualified. Reframing a specific skill gap as a concrete, learnable thing rather than a character verdict changes both how it feels and what you actually do about it.
Notice the comparison trap specifically
Comparing your visible output to someone else’s without seeing their actual process, effort, or private uncertainty is comparing a highlight reel to your own unfiltered experience. It’s a distorted comparison by design, not an honest one.
What Managers and HR Can Actually Do
- Build in feedback more frequently than the annual cycle, so uncertainty has less time to compound unchecked between formal reviews
- Be specific and concrete with praise, “the way you handled that client escalation was well-judged” lands and sticks in a way “good job” doesn’t
- Normalize not-knowing openly, a manager admitting their own early uncertainty in a role gives permission for a team member to admit the same without it reading as a competence problem
- Distinguish a real skill gap from impostor feelings before responding, someone newly promoted may need actual training or support, not just reassurance, and offering only the reassurance leaves the real gap unaddressed
Frequently Asked Questions
Q: Is impostor syndrome an actual diagnosable mental health condition?
A: No. It was originally named the “impostor phenomenon” by researchers Clance and Imes in 1978, specifically not a syndrome or clinical disorder, and it isn’t listed as a diagnosable condition. That doesn’t make the experience any less real or worth addressing seriously.
Q: Does impostor phenomenon only affect women, since the original research studied women?
A: No. Clance and Imes’ original 1978 study focused on high-achieving women, but subsequent research found it affects people across genders, and it appears more frequently among people from underrepresented or minority backgrounds in a given professional context.
Q: How is impostor phenomenon different from a genuine skill gap after a promotion?
A: A genuine skill gap is a specific, learnable thing tied to real, new job demands, closable with the right support. Impostor phenomenon persists even when someone has clearly demonstrated the relevant skill, the feeling doesn’t update even when the evidence does, which is the key distinguishing feature.
Q: Can a manager accidentally make an employee’s impostor feelings worse?
A: Yes, mainly through vague or infrequent feedback and by not distinguishing a real skill gap from impostor feelings. Generic reassurance without specifics doesn’t give someone anything concrete to check their feelings against, and can leave a genuine training need unaddressed at the same time.
Q: Does confidence-building training actually fix impostor phenomenon?
A: It can help at the margins, but on its own it tends to treat a symptom rather than the underlying pattern. Concrete, specific, frequent feedback and a genuinely psychologically safe environment to admit uncertainty tend to be more effective than generic confidence-building content alone.
Q: Is it normal to experience impostor phenomenon after every promotion or role change?
A: It’s common, especially in fast-moving job markets where rapid promotion is increasingly normal, but common doesn’t mean it should go unaddressed. A pattern that recurs at every transition is worth naming directly with a manager or mentor rather than treating as something to privately push through each time.
The impostor phenomenon persists precisely because the feeling doesn’t update even when the evidence does. A written record of real accomplishments, more frequent and specific feedback, and a workplace that distinguishes a genuine skill gap from a distorted self-perception all help close that gap, individually and organizationally.
