<p>Oh, so much to respond to</p>
<p>For SAT breakdowns that go beyond 25%-75% from MIT admissions, the best I have seen is here: <a href="http://www.mitadmissions.org/topics/apply/admissions_statistics/index.shtml%5B/url%5D">http://www.mitadmissions.org/topics/apply/admissions_statistics/index.shtml</a>
While mean scores are not reported per se, one can produce a pretty close estimate of mean scores from this data set. (which is left as an exercise for the reader).</p>

2) I don't understand the claim that if top admitted students choose not to attend the admission policy isn't meritocratic. It might not be maximzing the number of highly-rated students who enroll, but "meritocratic" is a property of the admissions procedure, based on an idea of procedural fairness, it is not a property of the outcome of that process in terms of enrollments.

<p>OK, I agree with Ben that the meritocratic nature of admissions is a quality of the admissions process rather than related to matriculation. However, Sakky is completely right when he says that having a meritocratic process is largely irrelevant to having a meritorious class, because you simply cannot ignore matriculation.</p>
<p>This reminds me of an exchange quoted recently on Jane Espenson's blog, where she recalls an episode of "Perfect Strangers" where Balki is testifying in court:<br>
Lawyer: Do you notice anything odd about this photograph?
Balki: It is borderless.</p>
<p>Balki's statement is completely true, and yet completely irrelevant. So is having a meritocratic admissions process.</p>
<p>In the context we are discussing, consider the completely meritocratic and fictitious Lower Kennicut Region Technical University in Kennicut, Iowa. This hypothetical college publishes precisely the GPA and scores necessary to get in. Indeed, it accepts all students with a SAT I Math and/or verbal scores >700. And yet, despite a completely transparent and meritocratic process, the college ends up with mean scores below 500, and with no admittees with scores above 700, because those students DON'T WANT TO GO. Meritocratic and meritorious are largely unrelated.</p>
<p>MIT is looking for a meritorious class, and to get that, they are willing to sacrifice some of the meritocracy, but not much. </p>
<p>I am an EC (an interviewer) and worse, an international one, where the admit rate is roughly 4%. Now that is even scarier than it sounds, because the US rate is bouyed up (or more correctly down) a bit by a number of students without much of a chance of getting in who are applying as a "reach" school. That doesn't happen very often with the international applicants. With one or two exceptions, everyone I have interviewed in the past 5 years has been extremely academically gifted. And yet, I know that MIT is going to only take 1 out of 27 of these extremely bright people.</p>
<p>So given these capable, distinguished, bright, likely to be rejected students, how does MIT pick them. The match criteria on the website sound fluffy and yet, in my experience, they are the surest indicator of whether people get in. And I can tell you, it was a big surprise to me when I started interviewing, but you can actually easily tell how well someone matches the school, quite a lot of the time.</p>
<p>I have met several bright, capable students with stunning scores who simply could not work with others. They by and large won't get in, but read any of mollie's posts on problem sets to see how happy that kid would be at MIT. </p>
<p>There is the (perhaps apocryphal) story of the applicant who brought their teddy bear to the interview, and all of the interviewer's questions were discussed with the bear at length before the candidate answered. The EC's report wondered if the candidate had the emotional maturity for MIT. </p>
<p>I have met a few folks who are robots, who read physics textbooks as a hobby and have no human friends to speak of (most of these won't get in, the most brilliant sometimes will).</p>
<p>In a purely meritocratic system, one that only looks at the numbers, most of these kids, some of whom may be quite damaged, will get in. Many of them may then be unhappy. </p>
<p>MIT has enough academically qualified applicants to fill their incoming class several times over. A purely fair, but entirely unsatifying system might be a lottery. Instead MIT tries to admit based on the match criteria on the website, and what they are actually looking for is for students who will be happy at MIT and who will thrive on the MIT experience. Literally how well they match MIT.</p>
<p>Caltech's meritocratic admissions do not really consider or care whether the students will be happy and thrive on campus (which is of course why many of them don't), merely whether they can do the work.</p>
<p>Is Caltech's system more transparent? Yes. </p>
<p>More meritocratic? Yes. </p>
<p>Better? In my opinion, not by a long way.</p>
