Are Atheists Generally Smarter Than Religious People?

I have truncated this headline of a really interesting and evocative article.  The actual article, on Huffington Post website, is titled: "Why Are Atheists Generally Smarter Than Religious People?" (http://www.huffingtonpost.com/entry/why-are-atheists-generally-smarter-than-religious-people_us_59385ac8e4b0b13f2c6677d2)

I very much lean toward atheism.  Although I have to say since Trump was elected I say a prayer every night for our future.  I'm sure it's learned behavior from my upbringing.  Bill Maher's brilliant documentary in 2008 titled Religious really made me come to a conclusion.  But I still have a huge curiosity of the massiveness and the complexity of the universe.

So maybe I'm an atheist.  But I know for sure that I'm NOT smarter.  The algebraic question in this article baffled me.  I simply do not understand algebra or math word problems.

This article is a very curious discussion.  And a great movie!
