From Greg Mankiw:
“President Summers asked me, didn’t I agree that, in general, economists are smarter than political scientists, and political scientists are smarter than sociologists?” [former dean Peter] Ellison told the Globe.
And the proof?
I believe this may be true: "Scores going in do not necessarily predict later results". However, many of us stories that go like this "HE made it into WHERE? For WHAT?"
Like that old joke "what do you call your friend that graduated last in her class in Med School?"
