Exploring the neurobiology of politics, scientists have found that liberals tolerate ambiguity and conflict better than conservatives because of how their brains work. Previous psychological studies have found that conservatives tend to be more structured and persistent in their judgments whereas liberals are more open to new experiences. The latest study found those traits are not confined to political situations but also influence everyday decisions. Liberals were 4.9 times as likely as conservatives to show activity in the brain circuits that deal with conflicts, and 2.2 times as likely to score in the top half of the distribution for accuracy. Based on the results, he said, liberals could be expected to more readily accept new social, scientific or religious ideas.
Personal note: The study used very conservative and very liberal subjects. I suspect there are all shades of grey in this matter of grey matter, and many of us would test somewhere in between these extremes.
