David Amodio, the primary investigator, found that the anterior cingulate cortex for liberals performs differently, allowing them to think more flexibly.
The work grew out of decades of previous research suggesting that political orientation is linked to certain personality traits or styles of thinking.

It appears that conservatives have not responded well to this work, and some have taken offense. I personally think this kind of work is a fascinating way to try and understand political orientation, but I wonder how much effect this really has.
