Look, you don't have to take it personally, not you or badecker but the fact is that the smarter and more knowledgeable you are the less likely you are to believe in a god.
I don't take it personally I am just letting you know that if the data I presented is accurate and I don't have any reason to believe it is not your statement is simply not correct.
It is technically accurate only for 50% of the population. For the other 50% the exact opposite relationship holds.
Edit: I read the chart like this. As you go from dull to average (70-100) or in other words everyone below average intelligence you are more likely to be theistic. As you go from average to genius (100-130) or in other words above average intelligence tend to be less theistic.
This is the correct reading with the highest probability of theistic belief's and a low probability of atheistic beliefs at an IQ of 100 = your everyday average human being.
