<p>The data you site from the website parchment.com has largely been discredited. Parchment doesn’t adequately reveal how it compiles its data, and its doubtful it uses the most comprehensive data available. </p>
<p>As a few surprising examples, according to Parchment:</p>
<p>53% of cross-admits choose Penn over Yale.</p>
<p>69% of cross-admits choose Penn over Brown. </p>
<p>60% of cross-admits choose Penn over Columbia. </p>
<p>56% of cross-admits choose Princeton over Penn.</p>
<p>80% of cross-admits choose Yale over Princeton.</p>
<p>There are many others but, as you can see, these numbers don’t pass the initial sniff test, and they certainly don’t seem to say much about actual revealed preferences (where I doubt Penn has an edge over Yale, or that Yale has such a dominant edge over Princeton).</p>
