Books that make you dumb

A chart of which are the most popular books at colleges, by SAT score. [Link]

1. Get a friend of yours to download, using Facebook, the ten most popular books at every college (manually -- as not to violate Facebook's ToS). These ten books are indicative of the overall intellectual milieu of that college.
2. Download the average SAT/ACT score for students attending every college.
3. Presto! We have a correlation between books and dumbitude (smartitude too)!

   Books <=> Colleges <=> Average SAT Scores

4. Plot the average SAT of each book, discarding books with too few samples to have a reliable average.
5. Post the results on your website, pondering what the Internet will think of it.

Yes, I'm aware correlation ≠ causation. The results are awesome regardless of direction of causality.
You can stop sending me email about this distinction. Thanks.

Awesome.
