<p>“The point really is, doesn't this really show how unreliable this ranking system is?”</p>
<p>-Not so much that it shows that the ranking is unreliable, but, like was mentioned, the schools from say spots 5 to 15 can be shuffled around pretty easily because they are so similar. Penn fell 3 spots, Northwestern 2, Hopkins 2, Chicago moved up 6, Cornell up 1, Duke down 3, etc. We all know schools don’t change that rapidly. All US News is doing is shifting schools around every year to sell magazines, it is, after all, a business. When I applied to Northwestern, it was in the top 10, now it’s 14, I’m sure, however, that the education that I have received has not changed in any meaning full way in the last three years.</p>
<p>Also, we shouldn’t put too much weight in the entire history of the rankings, just from one methodology change to another, as, any rankings produced with a different methodology is essentially a different ranking system.</p>
