First described by psychologists Suzanne Imes, PhD, and Pauline Rose Clance, PhD, in the 1970s, impostor phenomenon occurs among high achievers who are unable to internalize and accept their success. They often attribute their accomplishments to luck rather than to ability, and fear that others will eventually unmask them as a fraud.
Though the impostor phenomenon isn’t an official diagnosis listed in the DSM, psychologists and others acknowledge that it is a very real and specific form of intellectual self-doubt. Impostor feelings are generally accompanied by anxiety and, often, depression.
