Have you ever felt like a fraud? You think that one day your mask will be uncovered and everyone will know your secret. According to psychologists, this is a common feeling that many of us suffer from and it has a name: imposter syndrome. The term was coined by two American psychologists, Dr Pauline Clance and Dr Suzanne Imes, in 1978. Dr Clance and Dr Imes first thought the feeling was only experienced by high achieving women, but quickly found that men experienced it too. According to subject expert, Dr Valerie Young, women are more susceptible to imposter feelings because they internalise failure and mistakes - whereas men are more likely to attribute failure and mistakes to outside factors. However, those who belong to minority groups of whom there are stereotypes about competence also commonly experience imposter feelings. If you suffer from imposter syndrome, don’t worry you’re in good company; Maya Angelou, Robert Pattinson, Meryl Streep, Viola Davis and many more successful people have expressed feeling like imposters.
