MAYBE. Will the boycott actually strengthen the U.S. News rankings?
Personally, I think a more adversarial relationship between USNWR and the schools it rates would probably suggest more reliability. But at the top the rankings are useless, because they are designed to reinforce existing prejudices. The one year that CalTech wound up #1 on the college rankings, they immediately rejiggered the criteria to make sure the Ivy League ruled again.
