<p>UChicago is a really poor case study for how selective colleges may have changed over the last 15 years, because during that time, U of C has deliberately set out to recruit and admit a different subset of students than it attracted in the past (not to mention expand the college and change campus life drastically). If you wanted to look at a school like Yale - whose admissions strategy/philosophy has remained constant over that period - you could maybe draw some conclusions about how the student population has changed. But the fact that there’s been a change in the student body of a school that publicly and conhtroversially changed its admissions philosophy should not surprise anyone…least of all someone with a U of C education.</p>
