I've done years of social work with people with low IQ's, into the disabled range. There are a series of traits: Seeing the world in terms of good vs. evil, waving the flag and trying to be patriotic, etc. But it really has little to do with actual politics, and everything to do with a group people trying to fit in to a society they don't fully understand due to their disability. The problem I have with this study is this: So how am I supposed to feel about people with really low IQ's, e.g. developmentally disabled people? Am I supposed to be dismissive of them as conservatives?
There's certainly people in the low IQ range who like the simple narratives of good old fashioned Americans vs. all that's complex, weird, new, hard to understand, etc. But when we label them as conservatives (or racists, which is generally not true though this group will fail any test politically correct nuance) We are turning a blind eye to the Wall st. guys with millions of dollars, high IQs who are actually driving Republican policy, all to make ourselves feel superior. The Right wingers that matter are very capable people, and we should face that fact.
