Are there more American atheists than we thought? « Why Evolution Is True

I also like his: "I'm glad god made me an atheist".

Why Evolution is True, reports a recent survey which suggests as many as 30% of Americans may be atheist, in contrast to the more common estimate of 5-10%.

The proposition is that many atheists may "under-report" themselves, because of the hostile anti-atheist culture in the US. The authors of the study use various statistical methodologies to derive their estimate (which they acknowledge may still be out).
