Higher IQ's

[Cephus]

Is that really so?

Yes, however most claim that it is due to religious people being born in poorer countries with less access to education. I don't accept this explanation, because, when religious and non religious people are compared in the same countries there is a higher IQ average in the non religious side.

There have been dozens of studies done since the 1930s that consistently show that religiosity and IQ are inversely proportional.  There are many, many others that show that religiosity and education are likewise inversely proportional.  The smarter you are, the more educated you are, the less you tend to be religious.  Many of these studies have been conducted solely in the United States, it isn't about poor education in other countries, it's an apples-to-apples comparison.
