Partisan political types are pretty stubborn. New research shows we listen to ideas that reinforces our world view and shut out those that disturb our world view -- or make us question whether we made a wrong choice in our opinions.
The research suggests there are parts of our noggins that regulate emotion that come into play. A politician says something you agree with -- your brain lets it in and processes it. A politician says something you don't agree with and your brain turns up the "angry" knob that lets you keep it out.
Or something like that. Hey, it's politics, not brain science or rocket surgery or whatever. (WashPost)
