I think you misinterpreted my post. I am well aware that Princeton does not have a business school.
The point I am making is that if you are planning to get an MBA, you may want to approach the USNews undergrad ranking a little differently
Both Harvard and Stanford have great reputations and highly ranked business programs, if you plan to get an MBA and have been admitted to either one of them, it makes sense to take that offer because these schools do admit a significant percentage of their undergrad alums in their MBA programs( choosing between them is purely personal decision at this point)
Then we come to the next tier. MIT, Penn and UChicago also are ranked highly for undergrad and also have highly ranked MBA programs as well. These schools also like their undrgrads for their grad program. So given their relative MBA ranking, they fit in a single tier. Personally I wouldn’t put Penn in the same tier as Harvard and Stanford, because that suggests that a kid getting into either Penn or Harvard or Stanford would choose between these schools for undergrad based on personal preferences. I don’t think that is realistic given the relative prestige of the institutions today. I am sure there are exceptions though
I think choosing between Penn, MIT and UChicago is purely personal, since going to either school will significantly improve your chances to get into that school’s MBA program relative to the general pool of MBA applicants. I don’t think Northwestern belongs in that category even though it has a great MBA program because when given a choice between Northwestern and Penn, MIT and UChicago an overwhelming majority of kids would choose the latter three schools for their undergrad. That is just where things stand today. Ten or fifteen years ago, the situation may have favored Northwestern over UChicago, but not anymore.
We then come to the third tier of schools, namely Columbia and Yale. Clearly great undergrad schools, but slightly weaker MBA programs than the schools mentioned above. So if you are interested in an MBA eventually and mulling over an offer from Yale vs Penn or UChicago, I would choose Penn or UChicago, because you will get an excellent undergrad education and increase your chances to get into a higher ranked MBA program relative to the general pool of MBA applicants. If you go to Yale, you will increase your chances of making it into Yale, but relative to a Penn or UChicago undergrad, your chances at those schools will be lower ( not much, but still every small advantage counts). Yale’s MBA program is making great strides, but still doesn’t belong in the same tier as HSPCMKC
I have included Princeton in the final tier because an undergard from Princeton will still be an excellent signal for any top MBA program. The primary disadvantage with going with Princeton is that it does not have its own MBA program, so why risk it by going there if you can go to Penn, UChicago, even Yale. At least you get a leg up on admission to one MBA school. With Princeton you are competing as an outsider for every MBA school, albeit with a very strong brand. That is why it is in the same tier as Duke and Northwestern which have good undergrad reputations and solid MBA programs as well
What about Dartmouth, Cornell, Michigan etc? In my opinion their combination of undergrad and MBA ranking doesn’t put them in the same tier as the other schools mentioned above. That is my personal opinion. Once you go past the M7 super elite schools for MBA, you are in a different tier although Yale might break into this tier in a decade or so, displacing Columbia, given all the changes happening there.
