<p>Interesting analysis, Phuriku. I tend to agree that switching to ED would be a bad move for Chicago, in large part for the reasons you mention. However, I’m not so sure that Northwestern’s decline in class stats is just because of ED. In particular, the decline you mentions coincides with UChicago’s increases in class stats, selectivity, rankings, popularity, and applications. Maybe a significant part of the reason for the Northwestern changes has to do with changes happening at their crosstown rival.</p>
