Other than when you just found your province, of course.

I was thinking this through and the only answer that *might* make sense to me would be if one re-assigned all scientists to a single category and then ran a massive number of schools. But I think even then, the loss incurred by moving Professor -> Recruit somehow doesn't make this satisfying.

Just strikes me that unless I'm missing something, once assigned always assigned is the way to go, because those bonus points from Professors really add up.

Alternative suggestions?
