What’s the significance of a study that correlates high IQ with atheism? 

In a forthcoming paper for the journal Intelligence, Richard Lynn, emeritus professor of psychology at the University of Ulster, will argue that there is a strong correlation between high IQ and lack of religious belief and that average intelligence predicts atheism rates across 137 countries.

The immediate suggestion is that more intelligent people choose atheism because they’re not idiots like the rest of us.  Of course, this is not news.  Ivan, the middle brother in The Brothers Karamazov, was clearly the most rational and intellectual brother, and he was the clear atheist.  Alyosha, the youngest brother, had the faith of a child, but also more wisdom than his two brothers combined.  And he was no idiot. 

We could parse the study, too.  Correlation doesn’t necessarily equal causation.  And perhaps high IQ often leads to vanity, and vanity leads to pride, and pride goeth before atheism.  Or something like that.  I am sometimes intelligent, but I am also sometimes virtuous.  I’m sure some of you will really have your way with this one.
