If your specialty is new—as mine is—and they can’t therefore find experts with an opinion on it either way, you’re going to have a real hard time keeping your position, as there’s no one out there to validate your stature. Because of this, the system rewards conformity for junior faculty: That is, the safest route to tenure is to take a robust research topic that already has lots of interest and then outwork your peers. If you want to innovate, wait until later in your career.
