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.
Fans of Lil Wayne‘s music scored the lowest in SAT while listeners of Beethoven‘s work were among the highest scorers. The full chart is available at Music That Makes You Dumb.
To come up with this chart, Virgil used Facebook to determine the "Favorite music" at different colleges in US and then combined it with the average combined SAT scores of students from these colleges. He has done a similar exercise for books as well.
The musical taste vs SAT score chart maps the 133 most popular (out of 1,455) favorite music from 1,352 schools. In terms of music genres, it follows like this – Soca < Gospel < Jazz < Hip Hop < Pop < Oldies < Raggae < Alternative < Classical < R&B < Rap < Rock < Country < Classic Rock < Techno in increasing order of SAT scores.
