<p>I’m sure they do. </p>
<p>I don’t think the point was that they don’t admit introverts. I think the point was that they base admission decisions in part on LOR’s – and it has been suggested that some (not all) students are disadvantaged in the process because their high school teachers are not aware of their strengths, and fail to write strong letters of recommendation. </p>
<p>I’m just saying that Harvard (and similar schools), probably don’t care if they miss those particular students, because they are looking for applicants who stand out.</p>
<p>I’m not sure how common that is in any case, because as someone else noted, the student only needs 2 LOR’s. It’s hard to envision that no teachers at all notice the presence of a high power intellect in their midst.</p>
