""In a 2013 meta-analysis, led by Professor Miron Zuckerman, of 63 scientific studies about IQ and religiosity, a negative relation between intelligence and religiosity was found in 53 out of 63, and a positive relation in the remaining ten."
Define 'intelligence'
Define 'religiosity'.
Then please explain what your point is.
Even if it were true that atheists are more 'intelligent' that theists that says NOTHING at all about whether atheism is true or not.
