"If you want to tell whether someone is conservative or liberal, what are a couple of completely nonpolitical questions that will give a good clue?" Nicholas Kristof wrote. "How's this: Would you be willing to slap your father in the face, with his permission, as part of a comedy skit? And, second: Does it disgust you to touch the faucet in a public restroom? Studies suggest that conservatives are more often distressed by actions that seem disrespectful of authority, such as slapping Dad. Liberals don't worry as long as Dad has given permission. Likewise, conservatives are more likely than liberals to sense contamination or perceive disgust."
According to Kristof, "the upshot is that liberals and conservatives don't just think differently, they also feel differently."
