The Null Device
A chap named Virgil Griffith has correlated the most popular books at every college in the US (as fetched from Facebook) with that school's average test score to find a correlation between intelligence and favourite books. According to Griffith's study, the book most correlated with high scores is Vladimir Nabokov's Lolita, and that with low scores is the Holy Bible (not to be confused with the Bible, which is around the middle, just below Harry Potter); other books correlated with high scores are Ayn Rand's Atlas Shrugged, Kurt Vonnegut's Cat's Cradle, and Freakonomics, and books dumber than "I Dont Read" include various erotica and hip-hop/ghetto fiction, The Purpose Driven Life and Fahrenheit 451. Slightly smarter than not reading are the likes of Fight Club, Dan Brown and John Grisham, along with Shakespeare's Hamlet; sci-fi, fantasy and geek/fan-interest books like The Lord of the Rings, Dune and, umm, Eragon rate more highly. (Mind you, this is correlated to test scores, not cultural well-roundedness.)
It would be interesting to see one of these correlating a measure of intelligence (such as test scores) with other factors, such as favourite music (I imagine things that a lot of geeks listen to, like metal, industrial and prog rock would come out on top, and rap-metal/nu-metal and R&B would come out fairly low), movies, or even which Facebook groups/applications one has installed.
