D-oh! I could have told you that!

From Huffington Post:

Are religious people less intelligent than atheists?

That's the provocative conclusion of a new review of 63 studies of intelligence and religion that span the past century. The meta-analysis showed that in 53 of the studies, conducted between 1928 to 2012, there was an inverse relation between religiosity -- having religious beliefs, or performing religious rituals -- and intelligence. That is, on average, non-believers scored higher than religious people on intelligence tests.
