The US News rankings have a very negative incentivization for schools also. One of the things that my alma mater, Virginia Tech, used to do to (and I'm sure still does) is lure top tier students into their (admittedly great) engineering program. However, they then use a bootcamp style, much harder than necessary first year "weed out" program for the freshman engineering students. The effect is that 50% of the incoming engineering students fail out or are forced to transfer to the school's less prestigous programs, particularly business. The relatively high SAT scores of these students then allow these other schools to inflate their rankings with US News. By the way, I know for a fact that Perdue and a few other state schools with good engineering programs do the same thing.
The first time I saw videos of top tier freshman engineering, math, and comp sci courses, I was schocked. The problems were manageable, the pace was reasonable, the teachers were engaging..... and when I saw the course material and realized the tests were easier than the ones I took at my much lower ranked school, I realized I'd been had.
The worst, most socially irresponsible aspect of this practice of "funneling" and "trapping" your students into less desirable majors is that students who otherwise would have been engineers end up learning less useful things. Virginia Tech, and schools like it, are responsible for making the world have less engineers than it should.
