<p>A possible "but" -- maybe not universally applicable, but still perhaps worth considering: the top graduate school MIT undergrads choose to attend, at over twice the rate of the other popular graduate schools combined, is MIT itself.</p>

<p>LAC graduates obviously don't have the choice to attend their alma maters for graduate school.</p>
<p>I just feel like any analysis like this is sort of doomed, because from the outside it's very difficult to tease apart the many, many factors that go into admission and matriculation into graduate school. I mean, maybe all the MIT kids applied to Caltech, and none of them got in. Maybe they all got in, but decided that they really like blizzards and they should stay in Cambridge. The point is, it's impossible to tell.</p>
