Oh? You actually read the research article? Or you're just asserting that this information is inaccessible to prevent having to accept the validity?
In fact, I believe the specific study in question about the IQ of atheists being statistically significantly higher than theists is data taken from surveys conducted by the US Department of Labor, so the data wasn't even taken by the researcher in question, and your assertions of bias and skewed sampling fall flat.
