Of 1063 survey takers, 981 reported a karma score, and 466 reported that it was zero (Yvain instructed users to put in zero if they didn't have an account). I'm actually surprised there weren't more zeros.

Which is why you do exploratory data analysis, and look at your distributions first.
Me, I'm surprised that people who don't post bothered to take a long survey. You have to have an account to post, right? Do you have access to the system data, so that you could compare the distribution of karma scores for registered users versus the poll results?

Precommitted to publishing this in Discussion to fight publication bias. It looks like intelligence (as measured by IQ, SAT scores, etc.) isn't meaningfully related to how much one posts to LW. Probably in the ideal case, they would be related and higher-IQ people would post more, but that doesn't appear to be going on either.
How well-educated you are doesn't seem to be much related to participation either. I'm not controlling for hours spent on LW for any of this, though.
