Liberal or conservative? Reactions to disgust are a dead giveaway

    In a study to be published in an upcoming issue of Current Biology, an international team of scientists led by Virginia Tech reports that the strength of a person's reaction to repulsive images can forecast their political ideology.

    "Disgusting images generate neural responses that are highly predictive of political orientation even when those neural responses don't correspond with an individual's conscious reaction to the images," said Read Montague, a Virginia Tech Carilion Research Institute professor who led the study. "Remarkably, we found that the brain's response to a single disgusting image was enough to predict an individual's political ideology."

    In a brain scanner, participants were shown disgusting images, such as dirty toilets or mutilated carcasses, mixed with neutral and pleasant images, such as landscapes and babies.

    Afterward, the subjects took a standard political ideology inventory, answering questions about how often they discuss politics and whether they agreed or disagreed with hot-button topics such as school prayer and gay marriage.

    Using functional magnetic resonance imaging, scientists from the Virginia Tech Carilion Research Institute – in collaboration with researchers from University College London, Rice University, the University of Nebraska at Lincoln, and Yale University – recorded brain activity of the subjects responding to the images.

    Responses to disgusting images could predict, with 95 percent to 98 percent accuracy, how a person would answer questions on the political survey.

    The results suggest political ideologies are mapped onto established neural responses that may have served to protect our ancestors against environmental threats, Montague said. Those neural responses could be passed down family lines—it's likely that disgust reactions are inherited.

    "We pursued this research because previous work in a twin registry showed that political ideology—literally the degree to which someone is liberal or conservative—was highly heritable, almost as heritable as height," said Montague, who directs the Computational Psychiatry Unit at the Virginia Tech Carilion Research Institute.

    Conservatives tend to have more magnified responses to disgusting images, but scientists don't know exactly why, Montague said.

    The responses could be a callback to the deep, adverse reactions primitive ancestors needed to avoid contamination and disease. To prevent unsavory consequences, they had to learn to separate the canteen from the latrine.

    Montague points out that we're not necessarily hardwired to respond on instinct alone. He uses height as an analogy.

    "Genetics predetermines height – but not fully," Montague said. "Nutrition, sleep, and starvation can all change someone's ultimate height. But tall people's children tend to be tall, and that's a kind of starting point. If we can begin to understand that some automatic reactions to political issues may be simply that – reactions – then we might take the temperature down a bit in the current boiler of political discourse."

    People are unique among animals in their degree of cognitive control. Montague calls it a behavioral superpower.

    "People can deny their biological instincts for an idea – think of hunger strikes for political reasons," Montague said. "That requires a high degree of cognitive control, and that's the point."

    The takeaway message for Election Day?

    "Think, don't just react," Montague said. "But no one needs neuroscience to know that's a good idea."

    they discuss politics and whether they agreed or disagreed with hot-button topics such as school prayer and gay marriage.

    Did they ever bother to ask them how the felt about the government pilfering money from their paychecks each week to pay for all the worthless crap congress paid for to repay bribes?

    School prayer and gay marriage is a hot button issue to about 20% of the population. They will always vote republican until the republican party abandons them. Then they will just vote like any democrat for anybody that will give them more that they didn't work for.

    Show them a picture of a black welfare mom who is so fat and has no possibility of ever getting a job with her seven children and her food stamps and ask them if that is disgusting.

    Or why not just ask the piece of shit dumbass professor, "Why do you think people don't like socialism even though it means they will get more?" Sounds totally irrational to a shithead who has spent all his life in a University.

    Thank g-d we actually make a little money on student loans.

    If you show images of abortion, etc, you get an emotional reaction from religious conservatives.

    If you show the irs stealing people's money, you get the biggest reaction from libertarians.

    If you show the polar bears on a little tiny iceberg or an assault rifle, you get the liberals going nutso.

    Imo, this is was just another study to try to make people think that liberals are deeeep thinkers. Sciency, and all that.

    That's how you can get your research funded. Studies that prove libs are awesome. Help the cause.

    Just like like the global warming science bs. LOL
