The effect IS striking enough, however, that everyone in terminal-degree-granting institutions is well aware of it. The rate of psychosis among my graduate department seems to have been about 8-10% over a period of some 15 years that I'm aware of. Pretty sure that incidence is nowhere NEAR that in the general population, though I don't know exactly what it is.
During graduate school, when I doubted I would be able to finish and worried that I thrown away X years of my life, I was at times *very* unhappy. Finishing and getting a good job fixed that. I wonder if graduate school attracts people with psychological problems or creates them.
