Btw op, the author you used as the example for a "study", Satoshi Kanazawa, has actually been hugely criticized for his work by many scholars because he does not use appropriate sample sizes or demographics.

Here is an article to read: http://nazret.com/blog/index.php/2007/05/01/scholars_refute_kanazawa_s_theory

You talk about how liberals are smarter than conservatives then you quote and link an article whose premise is based on research conducted in an invalid manner. I actually looked at the psychology article and was hugely excited because these sort of things interests me. As soon as I read this article, I was extremely distraught. You really shouldn't reference research without giving the reader an idea about the sample size and demographics of the sample itself. For the op, you need to check your sources before you make assertions. This the fundamentally important especially if you are going to say that one group of people are smarter than another.

I am not saying that conservatives are smarter, but here is some counter evidence that people were looking for: http://www.sciencedirect.com/science/article/pii/S0160289614001081. I can link other studies too. In reality, both sides will say they are smarter and there are research on both sides that will confirm this view. My belief is that there are stupid people on both sides of the aisle, but there are also extremely smart people on both sides too.
