<p>Um, the survey only listed six of the top ten Ph.D programs (at least, as far as America is concerned.) The fact that more than half of them come from their own undergraduates is not exactly earth-shaking news. In fact, it’s rather sad. Presumably, the more top programs included in the survey, the higher Amherst’s tally would go, since Amherst has no incentive (nor ability) to hoard its own undergraduates for four+ additional years.</p>
