For the purposes of anything meaningful on CC, this is an unintelligible and meaningless ranking. University of California, San Francisco -- the de facto or functional equivalent of UC Berkeley's med school, but an institution that stands alone in spite of direct ties -- is ranked right up there with Harvard, for instance, a multi-faceted university that covers sciences, social sciences, and humanities. It's like comparing apples and ducks. (Oh, and by the way, UCSF is not just a med school; it has a small number of academic PhD programs in the life sciences, a dental school, and a nursing school too.)
It cracks me up that rankings get so much attention. I remember seeing a ranking in a California magazine that ranked MBA programs in the state. Number 1 was Pepperdine. Berkeley/Haas and Stanford ranked considerably down the list -- and the fine print disclosed the sole ranking criterion was size of student body.
What's the point of this ranking?
