Each year, I post a reader survey. This helps me learn who's reading this blog. But it also helps me try to replicate a bunch of psych findings, and investigate interesting hypotheses. Some highlights from past years include birth order effects, mathematical interests vs. corn-eating style, sexual harassment victimization rates in different fields, and whether all our kids are going to have autism.

This year's survey will probably take 20 - 40 minutes (source: it took me 15 minutes, but I knew all the questions beforehand, so I think it will take other people longer). As an incentive to go through this, I'll give free one-year paid subscriptions to five randomly-selected survey respondents. The survey will be open until about January 15, so try to take it before then.
