Now, if said person were to go out on the stump saying things like "The earth is flat. I know; I've got a Ph.D. in geophysics," where what the person was claiming fundamentally clashed with the nature of the work that earned the degree, then we would have a problem.
Could a PhD degree be retracted by the institution - say, for incompetence or misuse of the title?
