I don’t know that there are a particularly large number of surgeons changing to psychiatry. It may just be a sampling thing on this blog. If surgery converts are over represented, I suspect that it is the nature of surgery to be a discipline students feel obligated to enter into. “Of course my son would never go into psychiatry; he is going to be a surgeon.” Then the internship starts, the pressure seems relatively insignificant compared to the suffering and bingo, another psychiatric epiphany.
