Conservatives and liberals experience different brain activity when looking at images they find disgusting, according to a new study, Nonpolitical Images Evoke Neural Predictors of Political Ideology.

The researchers, led by Virginia Tech professor Read Montague, whose work will be presented in an upcoming issue of Current Biology, report that images showing dirty toilets and mutilated carcasses could be used to predict political ideology with up to 98 percent accuracy. In other words, conservatives reacted one way to the images (at least on a neurological level) and liberals reacted another way.
