The Impostor Syndrome Test This test maps how strongly you carry impostor feelings across nine dimensions of the impostor phenomenon — three validated core factors visualized on a radar, two perfectionistic drivers, and the four competence "masks" that route your archetype, with care-aware routing for when self-doubt runs high. LBL-original, grounded in current impostor-phenomenon research.
Drag each slider to where the statement sits for you, from 0 (not true of you) to 10 (very true of you). Your profile builds as you go, and your full Impostor Index is revealed once all 36 items are answered — nothing is submitted, and the calculation runs entirely on your device.
Clance observed that impostor feelings run in a self-reinforcing loop. Recognizing your place in it is the first step to interrupting it.
Your responses point to frequent, intense impostor feelings. Impostorism at this level often travels with anxiety, low mood, and burnout — not as a diagnosis, but as a load worth taking seriously. If this resonates, talking it through with a trusted person or a licensed professional can help. You are not alone in this, and these patterns are workable.
Across recent studies, self-compassion is the strongest known counterweight to impostor feelings — it consistently weakens the link between impostorism and distress. Treating your own struggle with the kindness you'd offer a friend is not soft; it is the mechanism that breaks the discount step of the cycle.

The Impostor Syndrome Test is an LBL-original 36-item assessment that measures nine dimensions of the impostor phenomenon — three core factors that anchor the composite and carry the heaviest weight, two perfectionistic drivers, and four competence masks that route the archetype. The framework synthesizes the Clance Impostor Phenomenon Scale (Clance 1985; Chrisman 1995), Valerie Young's competence-type model (Young 2011), the multidimensional Impostor-Profile (Ibrahim 2021), and correlate research on perfectionism, self-handicapping, and fear of success.
This page explains how the nine dimensions are organized, how each item is scored, how the composite Impostor Index and your archetype are computed, and — importantly — where the instrument rests on published evidence versus LBL design judgment. The instrument is in active development; a convergent-validity study against the CIPS and the Leary Impostorism Scale is planned but not yet complete.
The impostor phenomenon, first described by Clance and Imes (1978), is the experience of feeling like an intellectual fraud despite objective evidence of competence. It is not a clinical disorder — it appears in no diagnostic manual — and it is not the same as low self-esteem or social anxiety, though it often co-occurs with them. What distinguishes it is an attributional pattern: successes are attributed outward (to luck, effort, or help) while the fear of being "found out" is attributed inward, so accomplishment and reassurance never resolve the doubt.
A systematic review across 62 studies (Bravata et al., 2020) found lifetime prevalence estimates ranging widely but frequently near 70%, with impostor feelings especially common during transitions — a new role, a promotion, entering a field where one feels like an outsider. Clance further observed that the experience runs as a self-reinforcing cycle: a challenge triggers doubt, doubt drives over-preparation or procrastination, the resulting success brings only brief relief, and the achievement is then discounted — resetting the loop for the next challenge.
The goal of this assessment is not to label you or to rank you against others. It is to make the shape of your own impostor pattern legible — which dimensions are loudest, which cluster drives them, and which mask you tend to wear — because the shape is what tells you where to intervene.
LBL-IMP framing — synthesizing Clance's clinical model with Young's competence-type taxonomy and the modern multidimensional impostor literature.The nine dimensions are organized into three interpretive clusters. Cluster A (the felt experience) is the validated three-factor core of the Clance scale and carries the heaviest weight in the composite. Cluster B (the perfectionistic engine) captures what fuels impostor feelings, and Cluster C (the competence masks) captures the coping styles impostorism wears. Every dimension is measured with four items on a 0–10 scale (36 items total), with four reverse-scored items distributed through the core to guard against acquiescent responding. All wording below is LBL-original.
The defining feature of the impostor phenomenon — the felt sense of being a fraud whose inadequacy is about to be discovered. In factor-analytic work on the CIPS this “Fake” dimension carries the most variance; it is the experience most people mean when they say “impostor syndrome.”
Clance's central clinical observation was that impostors cannot internalize their achievements. Success is explained away, minimized, or forgotten almost as soon as it happens — the “Discount” factor — which is why external evidence of competence never accumulates into felt competence.
A distinctive attributional signature: success is credited to luck, timing, or the people around you, while failure is credited to the self. The “Luck” factor is what keeps the loop sealed — if you didn't really do it, there is nothing solid to stand on the next time.
Maladaptive perfectionism is the single most robust correlate of impostor feelings (Ferrari & Thompson, 2006). When the standard is flawlessness, every mistake reads as exposure and “good enough” never arrives — the engine that converts ordinary performance into chronic threat.
Clance described impostors as feeling not only fear of failure but fear and guilt about success — because succeeding raises expectations, invites scrutiny, and sets up a more public fall (Fried-Buchalter, 1997). Visibility itself becomes the threat, so people quietly avoid the very opportunities that would confirm their competence.
Young's “Expert” type measures competence by how much one knows, and so never feels qualified enough — always one more credential, one more course away from being allowed to claim authority. The dreaded question you can't answer becomes proof of fraudulence rather than a normal limit of anyone's knowledge.
Young's “Soloist” believes that needing help disqualifies the achievement. This links to self-handicapping (Want & Kleitman, 2006): asking for help is experienced as exposure, so people struggle alone and forgo the collaboration that competent performers rely on.
Young's “Natural Genius” expects to master things quickly and easily, and reads effort, struggle, or a slow start as evidence of inadequacy. This maps onto a fixed theory of ability (Dweck): if you were truly capable it would not be hard — so difficulty is taken as a verdict rather than as the normal texture of learning.
Young's “Superhuman” (Clance's “superwoman/superman”) measures worth by how many roles one can excel in at once, pushing to carry more than anyone expects. The load itself becomes the proof of adequacy — until it becomes unsustainable, which is why this pattern is the one most closely tied to burnout.
The composite is built in four stages, and — like every LBL assessment — it recomputes live on every answer rather than at a final submit.
Each item is answered on a 0–10 slider. The four reverse-scored items (q4, q8, q12, q28) are inverted — a raw 10 becomes 0 — so that for every item, higher always means more impostorism before it enters the dimension score.
Each of the nine dimensions is the mean of its four (direction-corrected) items, rescaled to 0–100. These are the nine values plotted on your radar and listed beside it.
The headline Impostor Index is a weighted mean of the nine dimension scores. The three Cluster-A core dimensions are weighted ×1.4, Perfectionism ×1.1, and the remaining five ×1.0 (weights summing to 10.3). This keeps the headline number anchored to the empirically validated CIPS spine while still letting the drivers and masks move it — a design choice, not a published formula (see the honesty section below).
The Index is mapped to five interpretive zones. These are LBL-original bands, not clinical cut-offs or population percentiles: Minimal (0–24), Occasional (25–44), Moderate (45–64), Frequent (65–79), and Intense (80–100). They describe how often and how strongly impostor feelings appear to show up for you, not a diagnosis.
Honesty about provenance is a standing LBL principle. Here is the line between what the research supports and what represents our own design decisions:
The overall Index sets the severity; the shape of your profile sets the type. The seven archetypes are:
Archetypes are computed from the dimension pattern, not from any separate items, so the type always follows directly from the radar you can see.
