I could kiss Leslie. That said, I’m leery of “biology is destiny.” I don’t want to believe that our views are hard-wired. However, we clearly have difficulty changing our views. Of course, we don’t know if brain differences are the result of attitude-views or vice versa.
From a study published in “Biology,” MRIs of self-reported liberals found more volume in the anterior cingulate cortex of the brain, which provides tolerance to uncertainty, whereas self-reported conservatives had more volume in the right amygdala, where fear is processed.
From another study published in “Current Biology”: “In general, liberals are more open-minded, creative, curious, and novelty seeking, whereas conservatives are more orderly, conventional, and better organized.” And another study in the journal “Dreaming” that is even less responsive to your question but still interesting found conservatives slept more soundly and had mundane dreams while liberals were more restless sleepers with bizarre dreams.
I resisted linking to a study that showed that when packaging compared energy efficient bulbs to wasteful bulbs without comment, conservatives and liberals both bought energy efficiency. But when packaging added environmental messages, conservatives shunned those bulbs. peace, mjh
