<li><p>Many binding ED applicants to Yale also submitted RD applications to Harvard. If admitted to Yale, of course, they were legally compelled by Yale to withdraw their Harvard applications. (Coitus interruptus, as it were.) Might these people have preferred Harvard if Yale hadn’t had a gun to their head? We’ll never know, will we?</p></li>
<li><p>Statistically, very few Harvard EA admits ever bothered, in the past, to apply RD to Yale. This is still true. In a process known as “trophy hunting”, those with a Harvard EA admissions letter in hand seldom see an RD admission letter to some other school as a “trophy” to be sought after.</p></li>
