@Chuchill - most serious social scientists realize that to marry three times in 10 years is probably NOT very correlated with much college at all. Also, @DunBoyer is correct that you can game the USNWR rankings pretty easily. Take a look at the controversy behind NEU, for instance. And the jury is still out on whether UChicago’s own increase is more like that institution’s, Stanford’s.
One shouldn’t depend on one particular ranking. Looking at the group of rankings as a whole (and understanding that there may well be some interdependence among the ranking agencies), one can see some consistency in terms of the ordering.
