In a simple experiment reported todayin the journal Nature Neuroscience, scientists at New York University and UCLA show that political orientation is related to differences in how the brain processes information.
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.
The results show "there are two cognitive styles -- a liberal style and a conservative style," said UCLA neurologist Dr. Marco Iacoboni, who was not connected to the latest research.
Analyzing the data, Sulloway said liberals were 4.9 times as likely as conservatives to show activity in the brain circuits (coulda ended that sentence right there - G) 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.
Harumph. I coulda told 'em that.
