Whew. The article referenced in the opening post, certainly is a mess, with almost all of the very worst aspects of modern day reporting exemplified in the one short piece.
Lots of vague labels used, as though they have meaning (“scientific study”, “theory”, “instinct”, etc) , while the body of the text itself, reveals that they don’t. At least, they don’t have the meanings that they ARE REQUIRED BY DISCIPLINED SCIENCE, to have, in order to be used in the manner that they are.
In my extensive studies of human history, AND of my own development from the time I was about six months old, I can affirm that there is ZERO evidence of any "instinct for religion." The example someone gave above of a child constructing a religious-like explanation for why puddles exist, doesn't match anything factual that I read or directly experienced. I myself recall directly, what conclusions I came to about what I observed as an infant, and it never even crossed my mind that anything magic was involved, or that anything remotely similar to "puddles exist to give animals a place to drink." The closest I could come to that, was that I clearly remember making the mistake of believing that whatever I saw BIG people do, was done by them on purpose, and for a good reason. And that had zero to do with an "instinct for religion," it was simply that I knew that I did things for my own reasons, and since they were (so far as I could tell) the same kind of animal I was, they probably did too.
So. No. There is no “instinct for religion.” And no. I have seen no evidence that “atheists are smarter than theists.” I have seen plenty of examples to the contrary in fact. Yes, I am an atheist. Yes, I am smarter than SOME theists I know. I am also smarter than some atheists I know.
The article also shows the common flaws with modern journalism, in that the conclusions it draws, are not supported by any of the evidence it presents which the author THINKS supports the claims.
So enough already. It’s bunk.
