|This is only mildly disgusting; so does that mean mildly conservative reactions?|
Conservatives, the report concludes, react more strongly to disgusting images like "maggot infestations, rotting carcasses, unidentifiable gunk in the kitchen sink" and the like. The study is published in the new issue of Current Biology.
It appears that "political ideologies are mapped onto established neural responses that may have served to protect our ancestors against environmental threats. Those neural responses could be passed down family lines – it’s likely that disgust reactions are inherited," says the release.
Says Montague, “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."
