Impostor syndrome is a psychological experience—not a disorder—first described in 1978 among high-achieving women. It describes persistent self-doubt and fear of exposure as a fraud, despite evidence of competence. It correlates with depression, anxiety, low self-esteem, and rigid, self-critical perfectionism. It is not in DSM-5 or ICD-11. It is studied as a reaction to stimuli—not a pathology. Its value lies in naming a real experience; its danger lies in disguising structural inequity as individual failure.
It is a subjective experience of fraudulence—not a diagnosis, not a disease.

What the thing is
Impostor syndrome is a psychological experience—never a clinical disorder—in which a person feels intellectually or professionally fraudulent despite evidence of competence.
Where it came from
It was first conceptualised in 1978 in relation to high-achieving women. It emerged as a descriptive label for a subjective pattern of self-doubt and fear of exposure.
What it gets right
It names a real, widespread psychological experience: persistent internalised fraudulence despite objective success. It correctly frames this as a subjective reaction—not a disorder—and links it to rigid, self-critical perfectionism and comorbid anxiety, depression, and low self-esteem.
What it gets wrong
It misleads by implying universality or clinical weight. It is not in DSM-5 or ICD-11. It is not a diagnosis. It is not a disorder. It is studied as a reaction—not a condition—and its framing often displaces structural causes like bias, inequity, or poor workplace design.
Why it matters now
Because it is widely cited in workplaces, education, and media—yet rarely clarified as non-clinical, non-universal, and structurally under-examined. Its popularity risks pathologising normal uncertainty while obscuring systemic barriers.
Is it worth your time
Yes—if you experience chronic self-doubt despite evidence of competence, and want language that names the pattern without medicalising it.
