Virgil Griffith has created an infographic/site called MusicThatMakesYouDumb wherein he combined the favorite musical artists from all the colleges (using Facebook) and correlated it the SAT scores of all the colleges in America.
How he did it is not important. What is important is that finding out that loving Counting Crows and/or Ben Folds and/or Guster (Maine represent!) makes you a smarter person than those who love Nickelback and Fall Out Boy, not that you needed the chart (but the chart is fun).
