What impostor syndrome actually is
The term was coined in 1978 by psychologists Pauline Clance and Suzanne Imes to describe a persistent feeling of being a fraud, and an accompanying fear of being "found out," that occurs despite clear external evidence of genuine competence and achievement.
Why Young split it into five types
In her 2011 book "The Secret Thoughts of Successful Women," Young argued that generic reassurance ("you're doing great!") often does not help, because the underlying self-imposed rule differs by type — a Perfectionist and a Soloist are struggling with fundamentally different internal standards, so the useful advice for each looks different too.
Frequently Asked Questions
Is impostor syndrome an official clinical diagnosis?
No. It is not listed in the DSM as a disorder — it is a descriptive psychological concept for a common pattern of thought and feeling, not a formal medical diagnosis.
Can someone fit more than one type at the same time?
Yes, this is common. Many people recognize traits from two or three of the five types simultaneously, and which type feels most dominant can shift depending on the situation.
