<p>Having the lowest acceptance rate does not necessarily indicate greatest selectivity. MIT has something around a 16% acceptance rate (although I believe it dropped this year) but does that mean that it is easier to get into than schools with lower acceptance rates like Brown, Columbia, even HYPS? I don’t think so. I hear so many people saying that Yale is now the most selective university simply because it had <9% acceptance this year, but this may not be entirely true, as selective as Yale is. It is also inaccurate to say that Princeton is “far less selective than Harvard or Yale.” On what grounds?</p>
