Liberals and Conservatives React in Wildly Different Ways to Repulsive Pictures - "To a surprising degree, our political beliefs may derive from a specific aspect of our biological makeup: our propensity to feel physical revulsion"
Some of the researchers had found similar results earlier.The brains of liberals and conservatives reacted in wildly different ways to repulsive pictures: Both groups reacted, but different brain networks were stimulated. Just by looking at the subjects’ neural responses, in fact, Montague could predict with more than 95 percent accuracy whether they were liberal or conservative.
The subjects in the trial were also shown violent imagery (men pointing revolvers directly at the camera, battle scenes, car wrecks) and pleasant pictures (smiling babies, beautiful sunsets, cute bunnies). But it was only the reaction to repulsive things that correlated with ideology. “I was completely flabbergasted by the predictability of the results,” Montague says.
A lot of earlier research agrees with that conclusion. Though the correlations found are not very strong, they are persistently present.Compared with liberals, they’d previously found, conservatives generally pay more attention — and react more strongly — to a broad array of threats. For example, they have a more pronounced startle response to loud noises, and they gaze longer at photos of people displaying angry expressions.
Using a far cruder tool for measuring sensitivity to disgust — basically a standardized questionnaire that asks subjects how they would feel about, say, touching a toilet seat in a public restroom or seeing maggots crawling on a piece of meat — numerous studies have found that high levels of sensitivity to disgust tend to go hand in hand with a “conservative ethos.” That ethos is defined by characteristics such as traditionalism, religiosity, support for authority and hierarchy, sexual conservatism, and distrust of outsiders.
