existential identity theft. (hella deep, fool)

In mild doses, feeling like a fraud also tempers the natural instinct to define one’s own competence in self-serving ways. Researchers have shown in careful studies that people tend to be poor judges of their own performance and often to overrate their abilities. Their opinions about how well they’ve done on a test, or at a job, or in a class are often way off others’ evaluations. They’re confident that they can detect liars (they can’t) and forecast grades (not so well).

This native confidence is likely to be functional: in a world of profound uncertainty, self-serving delusion probably helps people to get out of bed and chase their pet projects.
