To be fair, one of the reasons why I think that Stanford doesn't highlight the "can do/learn/explore anything" is because that's the vibe of Stanford grad life in general. Obviously, I'm drawing my evidence from the POLS info session I attended and having spoke to Stanford grad students but there are so many opportunities to take classes in other departments and many POLS classes are cross listed with GSB, law, policy, CS, sociology, etc. Just something to keep in mind
I understand the dilemma because I too, like others here, am debating between Stanford and Harvard.
