"A strange new study shows that the way your brain responds to photos of maggots, mutilated carcasses, and gunk in the kitchen sink gives a pretty good indication of whether you're liberal or conservative."

"While the researchers believe these differences in our reactions to disgusting images are likely "hard-wired" into our brains--that is, inherited from our parents--they argue genes might affect our political views similar to the way they affect our height"

"accepting that our brains are built to have differing political views could help ease political tensions."
