Take the top ten most popular books at each college according to Facebook, then look at the average SAT/ACT score for students at each college, and bam a list of
which books are smart and which are dumb. Given the dubious methodology, there's not much here of interest, but I was intrigued by the gap between
Crime and Punishment (super-smart) and
Anna Karenina (kinda middlebrow) which would seem to me to appeal to more-or-less the same audience.
