A study at University College London in the UK has found that conservatives' brains have larger amygdalas than the brains of liberals. Amygdalas are responsible for fear and other "primitive" emotions. At the same time, conservatives' brains were also found to have a smaller anterior cingulate -- the part of the brain responsible for courage and optimism.
So much for personal choice!
I'd be interested in who the exceptions are - those who've gone beyond thier genetic programming. My guess is they would have a more enriched understanding and outlook.
