I've seen a few graphs with a negative trend of intelligence vs religiosity. I suppose if you only look at countries with poor education they tend to have high religious take up as well so not a fair study.
"A new review of 63 scientific studies stretching back over decades has concluded that religious people are less intelligent than non-believers.
A piece of University of Rochester analysis, led by Professor Miron Zuckerman, found “a reliable negative relation between intelligence and religiosity” in 53 out of 63 studies."
