There could be many reasons why atheists score higher on IQ tests which these studies fail to consider. One example could be as man gains knowledge, status and financial power, his ego and pride also increase. This leads to the glorification of man, an ideal which the New World Order subscribes to. This was the case in ancient Babylon (which I might add is being rebuilt today). All too often when man gains pride, he is likely to reject the fact that there is a Creator or spur Him. If you read The Holy Bible you will see this is exactly what happened with Satan.
Also interesting to note, the people that own you, me and this entire planet are religious. Their god happens to be Satan. Their signature is on your currency among many other things you see and use in your daily life. Please take the time to look into it. It is unmistakeable. These elites are smarter that you and I and definitely score higher on IQ tests. You may not think this issue concerns you, however, you would be in error. These people run the planet and they control your destiny even if you are atheist.
