Religion vs I.Q.

[Tiberius]

IQ has nothing to do with how much education you have. They are indicators of how well you are likely to do in education. This is why IQ tests only require basic literary and math skills. Most IQ tests contain questions that ask about certain patterns and relationships, for example:

Hand is to glove as foot is to...

(Correct answer is "sock" or sometimes "shoe")

Besides, history has shown that there are an extraordinary amount of people from poor uneducated backgrounds who have genius level IQs. The fact is, there is a very strong positive correlation between intelligence and disbelief in God, mainly because people with high IQs are able to spot patterns and contradictions within religion more than people with lower IQs.

Also, in no proper scientific study would the "best fit line" on that graph be straight for the religion/gdp data. It is a clear curve. The religion/IQ data however is a clear straight line.
