<p>This thread is not about the Revealed Preference Ranking, but:</p>
<p>First off, here's</a> the link to the PDF, which I've put up for purposes of discussion.</p>

Denzera - I respect your views, however isn't the "Revealed Preference Rankings" a popularity ranking? And popular is not always better. I betcha the most popular person from your high school will not be the most successful person in life.

no. its methodology normalizes out the number of people who got into each school, such that while each data point (one school being picked over another, out of a pool of X to which they were admitted) corrects the numbers towards the information they're trying to reveal, nothing is weighted by the number of data points. The more students who applied (and thus got in) to Penn does not improve Penn's ranking relative to, say, Stanford, IF, given the option, those who were admitted to both Penn and Stanford tended to choose Stanford.</p>
<p>The most popular person in high school was very unlikely to go to Harvard. The "popularity" that this metric includes, if it can be said to include one, has nothing to do with that sort of popularity.</p>
<p>However, in some sense, all of college admissions is a popularity contest. The notion to going to college is a popular one, reinforced by societal pressure. But underneath that societal pressure is a number of very good reasons why a rational person, independent of that social pressure, might choose to go to college anyway. Similarly, there are a number of reasons underlying why people choose to go to Harvard when given the option. You can call it popularity, but they're measuring this in the most scientific way possible, with the most amount of noise removed from the data.</p>

The revealed preference rankings don't mean a lot- it's based on what schools applicants pick BEFORE they attend. The choice that is used as the basis for the ranking is a largely uneducated one, as one can't really know much about what school is like until they go.

Right, but that is the only point at which they have a CHOICE of school. After they attend, they may rationalize that choice for any of a large number of reasons. But when they are presented with a choice of multiple very good universities, where do they go? I think there's a lot more information (with a lot less noise) in that data than there is in any other set - which is why I keep referring to it like I had written it or something :)</p>

I agree with kmatimber2. Also, the revealed preference ranking is based on what schools students pick among those they've applied to. There is an earlier preference at work when choosing where to apply. And, in the end, it just tells you something about your fellow USNWR-influenced high school students rather than the college.

First off, the issue of bias based on where these students choose to apply comes off the data, if you read their methodology. They're quite brilliant about it. Your latter point is correct, however.</p>
<p>The bigger trouble is that no ranking system that talks about "the college" has fewer objections than this one. Most people find the whole system to be hopelessly out of whack - and I frankly agree. Many of the top colleges are SO different - in campus atmosphere, academic specialties, student-body "personality", etc - that trying to rank them is a fool's errand. However, for those who absolutely must have a sense of how they all stack up, this seems like the, uh, "least unintelligent" way of doing so.</p>
<p>edit: pages 1-3 of the RPRs, just after the "Executive Summary", explain their justification for what they've done much better than I can in a post.</p>
<p>...and Forbes' method is, shall we say, more unintelligent. As other posters have detailed quite well above.</p>
