<p>Your speculation is interesting, but I'd rather hear the real story from the mother of the girl involved. </p>
<p>As a New Englander, and as a recruited athlete with a strong chance of getting in wherever she applied, she seems to have been a different sort than the kind of person you are speculating about, and very likely more informed about the schools to which she applied. She seems to have developed a long, specific list of negative sentiments with respect to Harvard - not all of which could have been acquired after admission, one wouldn't think - which is why it is odd that a person sure to have many choices would have included Harvard on her list at all.</p>
<p>Obviously 20% of those admitted to both Harvard and another school go elsewhere. The great bulk of the 400 or so in this category go to Stanford, Yale, Princeton or MIT. Others often go to schools where they get athletic or other "merit" scholarships that are financially advantageous. The numbers choosing Ivies other than Yale or Princeton is very small, and, from what I can gather, often includes those with a particular pull - such a legacy or athletic recruit preferring the coach at the chosen school.</p>
<p>It is no surprise when school A "wins" in head-to-head battles with school B; by the same token, school B may have an equally large common admit margin vs school C.</p>
<p>The academic pecking order is quite rigid.</p>
