I’ll try and bring this back to my original point. The world rankings are useless to me in that they don’t provide helpful information for choosing an undergraduate school for my kids in the U.S. ; they appear to be of limited utility for law school rankings as well, but beyond that I’ll punt.
I don’t agree that prestige does not matter and the fact that some Chinese person from wherever has never heard of Yale is no relevance IMO. To the extent prestige matters here, which I think it does, the people who matter have certainly heard of Yale and recognize what attendance there means. And with that in mind, prestige does in fact matter in some contexts, though not at all in many others. Knowing the opportunities to which you could have access by attending Dartmouth over Arizona State is information that is worth knowing for a lot of people. So it’s too simplistic to say it doesn’t really matter, and the fact the someone somewhere in Asia hasn’t heard of it or Princeton is of zero relevance to me and I suspect most people who know and understand what those schools offer and attendance implies. And prestige certainly matters in law school and the legal profession. It’s practically determinative of where you’ll start your legal career. Few professions are as prestige obsessed as the law.
