According to one study, the answer is yes.
In a survey of IQ measures in “elite” institutions, researchers argue that physical scientists (biology, physics, chemistry, etc.) have overall higher IQ’s than their social scientist counterparts. They then argue that the kind of reasoning in physical science is superior because of its reduced emotional influence.
“[Physical] scientists are overwhelmingly atheist,” Dutton said. “This is predicted by their high IQ, which allows you to rise above emotion and see through the fallacious, emotional arguments.” Arguments about God are all emotional arguments, he added.
There are very obvious problems in the research. First, it focuses on a particular sample of scholars where even if the data is true, science demands the method be tested to see if the conclusions are even valid. Second, the use of IQ as a measure of intelligence is suspect. Numerous papers have been published arguing the validity of IQ as a measure of intelligence or aptitude.
Finally, the claim that arguments about God are all emotional is made with no evidence to support it. It is hard to imagine that massive works of logic and reasoning about God such as St. Thomas Aquinas’ Summa Theologiae, or Karl Barth’s Church Dogmatics, or the centuries of theological thinking are all emotional in nature. In fact, at one point theology was called “the mother of all sciences.” Therefore, this assumption perhaps reveals a hidden agenda that is ironically rooted in emotion. Similarly, Richard Dawkins likens theology to the study of leprechauns and that it has no business as a university discipline.
Research probes the truth, no matter how uncomfortable. It may be true that scholars of physical science have high IQ’s. However, it is an unscientific stretch to say that their reasoning is superior and such superior reasoning is why they are correlated with atheism. Good science means that we cannot confuse a correlation with causation. Thus, the research conducted here is unscientific and shoddy at best.
