Is it possible to be over-educated when real knowledge is concerned? (Perhaps if it is not appropriate to one's calling, in which case it is tied to the vice of curiositas.) Some prefer a variation in order to emphasize that it isn't true education; is that effective rhetoric? Or would over-credentialed or over-certificated be better? What would be most effective against the modern Uhmerican woman who thinks she is all that because of the degrees she has?
