Creativity

Over at Althouse, I found an interesting discussion. Are liberals more creative/artistic than conservatives? It's certainly true that movies and music tend to be more liberal. The people who make them tend to be more liberal. Why?
I'll share my comment from the thread:

I think you find this same thing happening even on a local level. If you were to go to a community Ed art class, you'd be much more likely to find majority liberal crowd. The same thing is true of community theater. Don't really know why this is, but the easy answers like practicality, ability or rebellion don't really ring true to me. My theory is that liberals find being in touch with emotional things more important than conservatives do. They tend to see art as an emotional demonstration.
BTW, this may fit with Ann's remark. Great, longlasting art probably has more to do with eternal themes. Conservatives are more comfortable there.
