Virgil Griffith, popularly known for the Wikipedia Scanner that detects where the Wikipedia edits are coming from, maintains another very interesting project that maps musical tastes of college students with their intelligences levels (determined by their SAT score).
The x-axis represent the SAT score while the colored boxes indicate the music genre and the artist / composer.
To come up with this chart, Virgil used Facebook to determine the “Favorite music” of students in different colleges in the US and then combined their taste with the average SAT scores of students from these colleges. Smart.
