left brain, right brain


Scientists at New York University and UCLA show that political orientation is related to differences in how the brain processes information. Liberals tolerate ambiguity and conflict better than conservatives because of how their brains work.
I know, like this is news?
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.
Again, nothing we didn't know, but it's always nice to have more evidence.
Each participant was wired to an electroencephalograph that recorded activity in the anterior cingulate cortex, the part of the brain that detects conflicts between a habitual tendency (pressing a key) and a more appropriate response (not pressing the key). Liberals had more brain activity and made fewer mistakes than conservatives.
Sound like anyone we know???
liberals were 2.2 times as likely to score in the top half of the distribution for accuracy. Based on the results, liberals could be expected to more readily accept new social, scientific or religious ideas.
That sounds about right.
