<p>There is absolutely no evidence that an increase in the number of applications by a few candidates is having any negative effect on the admission of the rest of the applicants pool. </p>
<p>If that were true you would find an increase in the number of multiple admits and a decrease in yield as more admitted student fail to enroll when admitted. The data shows the opposite. As admission rates have been going down, yields have actually gone UP not down. Here is the comparative data for the top universities over the past ten years. </p>

<p>If you are looking at the top of the pyramid at the HYPSM pool, the number of multiple admits has gone steadily down. Fewer and fewer students are admitted to more than one of the five schools. With an average of 70% yield up from 60% ten years ago, more and more of the students admitted actually enroll. They simply have fewer choices than 10 years ago. Of the 30% “excess” admissions, a large percentage is from students who enroll outside of HYPSM for financial or other reasons. Most likely no more than half, or 15% of the total acceptances are for cross-admits. That is less than 1,000 students with multiple admission offers at the most selective schools. This is consistent with statements by Deans of Admission at Harvard and MIT that around 15% of the enrolling students are so-called “super-candidates” with virtually guaranted admission based on merit (Olympiad winners and the like..). Valecdictorians and 2400 SAT scorers are routinely rejected. For the remaining 85%, acceptance was always a longshot. The only way a highly qualified candidate who is not a super-candidate can maximize his chances of admission to one of these schools is by applying to all of them. The colleges themselves say as much. Chance plays a larger and larger role in admission. You just have to play the odds. </p>
<p>You find the same phenomenon repeated at LACs and at each leach level of selectivity. If a student wants to be accepted to a top LAC, he’d better apply to as many that he feels he can reasonably feel attending. There just will not be many multiple offers as the yield data shows. </p>
<p>Even state universities have seen their yields go up. If the increased selectivity was somehow caused by overqualified students who were admitted but failed to enroll, you would find a rise in the median SAT of the admitted pool and a lower yield. But what you are actually finding is an increase in yield and a rise in the median SAT of the matriculating pool. More qualified students are applying AND enrolling. </p>
<p>The issue of “fit” has been vastly overplayed. Within a geographic region, the students bodies at colleges with a similar selectivity are virtually indistinguishable. You could shuffle the students at HYPSM around and you would find very little difference. Same thing with most LACs within a range of selectivity.</p>
<p>What you do give up by limiting yourself arbitrarily to a specified number of applications is choice and most likely quality as well. If you only apply to two or three reaches and one or two matches, there is a significant chance you will end up at your safety.</p>
<p>So don’t blame the increased selectivity on the applicants that do their homework, blame it rather on the baby-boomer parents which (pro)created this huge supply of students competing for a fixed set of slots.</p>
