Apparently, size matters.

Scientists at University College London studied the brains of people with liberal and conservative political views. They found conservatives are amygdala-driven, while liberals have a more developed anterior cingulate cortex; that's linked to rational cognitive functions. Wait. There's more. The University of Iowa reports on a woman with a damaged amygdala who is literally without fear. Yet a study at Harvard Medical School shows that folks with bigger amygdalas have more extensive and complex social networks. Normally, I would punctuate each of these little stories with a joke. But I won't insult your anterior cingulate cortex by spelling them out.
