<p>"Well, over 200 deferred applicants are not admitted in RD. Byerly, an alumnus of Harvard, released stats on the number of RD admits from EA deferees. My year (Class of 2009), there were about 94 students. This is not 200."</p>
<p>I guess in 1998, it was about 222. But I don't think the exact number is important.</p>
<p>"I never said SCEA could not be a "tip factor." "</p>
<p>So you are willing to believe that it could be used as a tie-breaker but not to prefer someone a bit lower at the expense of someone a bit higher. How come? What compells admissions officers to use the EA factor only if they anticipate a tie but not otherwise?</p>
<p>"You are trying to prove that applying EA is an advantage in its own right and you're interpreting "advantage the advantaged" in simpler terms, extending the terminology to include weaker applicants"</p>
<p>Yes I am. But not to include infinitely weaker applicants.</p>
<p>The term "advantaging the advantaged" has two advantages in it. The first refers to all the things you mention:</p>
<p>"EA are usually from advantaged backgrounds where they know how to apply for highly selective colleges. Again, they have stronger test scores, grades, extracurriculars, personal qualities, etc. because they know the system."</p>
<p>What does the other advantage refer to? Remember, these guys are already advantaged, why would EA further advantage them if EA itself was not going to lead to better treatment?</p>
<p>"Why should they, with its 80% yield rate?" </p>
<p>The "they" here refers to Harvard. First, I never suggested that the only benefit (or even the main benefit) of EA was to increase yield. Although, I would not ignore this either. Asking why would a school with 80% yield do stuff to improve its yield is a little bit like (and I emphisize the little bit here) asking why would the rich cheat on their taxes: there are always two answers to such questions: (1) to get even richer, (2) how do you think they got to be rich in the first place? But there is a more important reason for favoring EAs: if you dont' they go elsewhere. Imagine yourself as the dean of admissions: suppose you have 100 applicants, your ranked them on some scale. You have a 100, a 99, a 98 etc all the way to a 1 in your EA pool. Suppose your best guess is that you will have to accept people down to 81 in you RD pool if you accept 19 ppl from your EA pool. But if you admit only 19% some applicants will be disappointed and will apply EA to yale next year instead of Harvard. You will lose 2 good applicants if you admit only 19%, a 90, and an 88. Would you be willing to accept the 80 from the EA pool this year, end up admitting only down to 82 in the RD pool to get the 90 and 88 next year? Sure it is a bad deal for this year: you ended up replacing an 81 from the RD pool with an 80 from the EA pool. But you more than make up for it next year. Wouldn't you go for it?</p>
<p>Now, all this would not work if the applicants themselves new their numbers, i.e., whether they would get in or not. But they don't. A 90 doesnt know that she is a 90, so she has to use her EA advantage wisely. If Harvard isn't favoring EAs, she has to apply to some school that is. Do such things happen? Of course they do, why do you think the EA pool shrunk by 13% at Yale this year?</p>
