Dang, I wish I had thought of this. A nice analysis of reading tastes versus SAT scores that really makes you go hmmmmm. The gist is that you get the ten most popular books at every college (which you can do these days), corellate that to the average SAT score of the college, and presto: books that make you dumb.

It's funny, slap more text onto this and you've got a masters thesis or a pretty damn good journal article (and one with more empirical data than many in scholarly library literature land). (thanks jessamyn)
