To paraphrase: "The brains of people who call themselves liberals tend to have larger anterior cingulate cortexes than the brains of people on the opposite side of the political spectrum, the study showed. The anterior cingulate cortex is a collar-shaped region around the corpus collosum, a structure that relays signals between the right and left hemispheres of the brain.
What about conservatives? Their brains tend to have larger amygdalas. The amygdala is an almond-shaped structure located deep within the brain.
Based upon what brain scientists know about the function of the two brain regions, researchers believe the structural differences support the notion that liberals are better equipped to make sense of conflicting information while conservatives are better able to recognize a threat.
So what does this mean?
I think it clearly explains why simple facts won't work on conservatives. They see or hear something, label it a threat, act on those impulses, and make decisions accordingly.
So I think we have to meet them where they are. We have to approach subjects such as gay marriage, environmentalism, military budget cuts, reproductive rights, etc. and promote the inherent safety of these ideas. We have to help them see there is nothing to fear. We have to neutralize the threat so they can think more clearly.
