There is widespread research investigating the prevalence and impact of the impostor phenomenon as experienced by university students. My own research has indicated that people who believe themselves to be ‘other’ and experience IP at uni may have a much diminished experience, their capacity to achieve can be stifled and in some cases they will change courses or drop out altogether.
It doesn’t need to be this way. Mentoring is an effective mechanism to diminish the experience of IP, but mentors need to know what IP is and how they can help. TYFY (third year, first year) is a brilliant initiative that matches third year students with first year students as mentors. Check out this piece that they kindly commissioned and published. https://tyfy.co/2020/04/23/its-a-syndrome-and-other-myths-a-guide-for-university-mentors/
