<p>Yale’s system has a couple of advantages over Harvard’s otherwise very similar system:</p>
<ol>
<li> Freshmen at Yale already belong to a college. So they can join the college’s intramural teams, singing groups, etc.; indeed, they are recruited to those organizations, welcomed with open arms. They eat in their colleges sometimes, too. They thus have a lot of casual social contact with upperclassmen (contact that doesn’t depend on being attractive and being hit on by the upperclassmen).</li>
</ol>
<p>Also, all of the academic advising is done through the colleges, so there is continuity in advising from freshman year on, and opportunities for casual contact with faculty associated with the college beginning freshman year.</p>
<ol>
<li> The Harvard system can cause a lot of stress in freshman spring as blocking groups are formed – who is in what group, what groups associate with each other or not, where everyone ends up. You are assured of being with your closest friends (if you are certain you know who they are), but you may wind up half a mile away from your next-closest friends. At Yale, there are fewer choices to make, so a lot less drama, and if you aren’t rooming with people you like, you will still see them every day.</li>
</ol>
<p>The great part of the Yale system is not your closest friends, but the people you wouldn’t be friends with at all if you hadn’t lived near them for four years and eaten with them on a regular basis. Harvard produces some of the same effect, but there’s a year less of it. On the other hand, at Harvard you wind up with freshman dorm friends all over the place, not just EC or class friends, while at Yale 99% of your freshman dorm friends are still in your dorm when you are a senior. So at Harvard you may know a few more people in a few more houses.</p>
<p>I note that Harvard changed its system about 20 years ago to make it a lot more like Yale’s. It used to be that Harvard freshmen applied to the houses of their choice, and had to be accepted by them, and only then could they form their living groups (unless you got a group of people together to apply to unpopular houses where acceptance was assured). Back then, the houses had different characters, and did not necessarily have a broad range of students in each one. By moving to a much more random system, Harvard affirmed that Yale had been doing something right all along.</p>
