<p>Not to mention that certain Nobel laureates are affiliated only with certain schools or certain departments within a particular university and practically never interact with students at that same university who belong to a different department. </p>
<p>To give you an example, while Robert Merton is indeed active at Harvard, he’s essentially only active within HBS. So his value to anybody at Harvard outside of the HBS community is questionable. This is simply because all of the various Harvard schools are highly territorial and insular, and HBS is arguably the most territorial of all of them, having its own gym and own dorms which are off-limits to anybody outside of the community, and almost never letting in undergrads into any of its classes. Similarly, undergrads have limited contact with Nobel Prize winners at many other universities who have ensconced themselves in a manner to effectively insulate themselves from undergrads.</p>
