Scientific studies show conservatives are dumb

5 Scientific Studies That Prove Republicans Are Just Stupid]
At last, we have peer-reviewed evidence of what we have known for a long time: conservatives are less educated than liberals, and engage in low-effort thought. But wait, it gets better. Researchers have found the cause. Conservatives’ brains have larger amygdalae than liberals’ brains, while liberals have larger anterior cingulate cortices. The amygdala is the part of the brain responsible for fear, while the anterior cingulate cortex processes complex thoughts.
Explains a lot.

Check out some of John Dean’s book. He says pretty much the same thing, and really gets into their heads, as well as references similar studies.
