Impostor syndrome, also known as
impostor phenomenon or
impostorism, is a psychological experience of intellectual and professional fraudulence.
[1] One source defines it as "the subjective experience of perceived self-doubt in one's abilities and accomplishments compared with others, despite evidence to suggest the contrary".
[2]
Those who have it may doubt their skills, talents, or accomplishments. They may have a persistent
internalized fear of being exposed as frauds.
[3] Despite external evidence of their competence, those experiencing this phenomenon do not believe they deserve their success or luck. They may think that they are deceiving others because they feel as if they are not as intelligent as they outwardly portray themselves to be.
[4]
Impostor syndrome is not a recognized psychiatric disorder and is not featured in the American Psychiatric Association's Diagnostic and Statistical Manual nor is it listed as a diagnosis in the International Classification of Diseases, Tenth Revision (ICD-10). Thus, clinicians lack information on the prevalence, comorbidities, and best practices for assessing and treating impostor syndrome.
[5] However, outside the academic literature, impostor syndrome has become widely discussed, especially in the context of achievement in the workplace.
