Imposter Syndrome
noun /ɪmˈpɒstə ˈsɪndrəʊm/ — The persistent feeling that you don't deserve your success.
Definition
A psychological pattern in which a person doubts their accomplishments and has a persistent fear of being exposed as a fraud, despite objective evidence of competence.
Beyond the definition
First identified in 1978 by psychologists Pauline Clance and Suzanne Imes. The research consistently finds it's most common among high achievers — the more capable you are, the more accurately you perceive your own limitations. Knowing this doesn't make it go away.
Origin & history
Coined in 1978 by psychologists Pauline Clance and Suzanne Imes in their paper on high-achieving women who believed they were 'imposters.' The term has since expanded to describe a universal human experience.
