You've probably heard the claim that babies who listen to Mozart or other classical music while still in the womb turn out to be smarter. Even though the scientific community at large sees no link between the two, the idea is still going strong. It could be because a lot of studies show some kind of correlation between music and cognitive ability. For example, kids who play a musical instrument tested higher on the SAT and in reading comprehension tests according to one study.
So could there possibly be a link between musical tastes and intelligence? One guy on the Internet is asking that very question. His results show that people who listen to Beethoven and Sufjan Stevens have the highest average SAT scores, while people who listen to Lil' Wayne and Beyonce scored lower. Now, this study doesn't prove anything - it's not very scientific. I'll tell you how it works and why I don't think it's a good indicator of anything.
This guy, Virgil Griffith, used Facebook to determine the most popular "Liked" music artists at various colleges around the country. That means he looked at all the Facebook profiles of people who identify themselves as having gone to, for example Arizona State University. Then he took the most common musical "Likes" of those people and chose the 10 most frequent - maybe Taylor Swift, Jimi Hendrix, rap, etc. Then he found out the average SAT score of ASU and correlated the two. He did this for many schools across the country and averaged them all out. That's how he came to his conclusions.
You probably already know that this isn't very scientific. Obviously correlation doesn't imply causation. But even so, it's still a fun game you can play. Where did your favorite music land on the spectrum? Let me know in the comments.
