It's interesting how big the correlation is. I might have expected only a few percent WRT music.
I want to see the correlation between Ayn Rand books and number of friends.
However, I guess he wasn't looking at their whole collection but just the stuff they mentioned on facebook, which reflects their social aspirations. So, for example, I have both Lynyrd Skynyrd and Chopin in my iTunes collection. But people who mention one of those in their facebook profile are probably very different from those who mention the other.
To correlate against the SAT is an implicit bias.
suggests a rather disturbing issue about what preparation students bring into the testing room when they take the SAT. The lines on the charts (you can click on them to see them at a more readable size) by ethnic group are from a College Board report that was apparently only issued in that format once, so disturbing are the implications of the differences among test-takers shown there. College Board gathers that information every year, but it's not presented in such convenient visual form in the official College Board reports.
The repetition of the "runner:marathon::oarsman:regatta" question item (which is based on a whole question type that has not been on the SAT for years now) as an example is suspect too. When I took the SAT, far inland, I had certainly never seen a regatta, because I had never seen a coast. But I had read about a lot of things I had never seen. (I had never seen a marathon either, but I knew what one was from reading.) In general, why should a college actively prefer a student who scores lower rather than higher on the SAT?
But maybe this kind of serious discussion of issues is just what the submitted article was NOT meant to elicit. Some of the comments seem to be missing the evidently humorous point of the man mentioned in the submitted article. He's having fun with ideas that people get very worked up about.
That said, I'm white, and I also learned about regattas by reading about them in a book somewhere. I was bummed out when they got rid of analogies on the SAT. I studied hard to learn new words so i could do well on that part, which I found difficult.
I heard about it on a podcast..I think it's either "How stuff works--stuff you should know" or "RadioLab", and they cited a study where they had a golf test for blacks and whites. The only variable was in telling them what it measured. When the experimenters told them it measured athletic intelligence, the blacks did worse, and the whites did better. When the experimenters told them it measured natural talent, then the vice versa happened.
