Study shows conservatives have more capacity for anxiety and emotions but less for courage and positive outlook

Political views 'hard-wired' into your brain - Telegraph
Excerpt:

Scientists have found that people with conservative views have brains with
larger amygdalas, almond shaped areas in the centre of the brain often
associated with anxiety and emotions.

On the other hand, they have a smaller anterior cingulate, an area at the front
of the brain associated with courage and looking on the bright side of life.
