This doesn’t surprise me at all:
The test subjects on both sides of the political aisle reached totally biased conclusions by ignoring information that could not rationally be discounted, Westen and his colleagues say.
Then, with their minds made up, brain activity ceased in the areas that deal with negative emotions such as disgust. But activity spiked in the circuits involved in reward, a response similar to what addicts experience when they get a fix, Westen explained.
The study points to a total lack of reason in political decision-making.
“None of the circuits involved in conscious reasoning were particularly engaged,” Westen said. “Essentially, it appears as if partisans twirl the cognitive kaleidoscope until they get the conclusions they want, and then they get massively reinforced for it, with the elimination of negative emotional states and activation of positive ones.”
So the question for civil society is, how do we reward serious thinking?
