Liberal, Conservative brains function differently

September 9, 2007

This doesn’t say, however, if people are liberal because they are more flexible, or if flexible people gravitate toward liberal politics. But it’s an interesting study, nonetheless.

The brain neurons of liberals and conservatives fire differently when confronted with tough choices, suggesting that some political divides may be hard-wired, according a study released Sunday.
Dozens of previous studies have established a strong link between political persuasion and certain personality traits.
Conservatives tend to crave order and structure in their lives, and are more consistent in the way they make decisions. Liberals, by contrast, show a higher tolerance for ambiguity and complexity, and adapt more easily to unexpected circumstances.
The affinity between political views and “cognitive style” has also been shown to be heritable, handed down from parents to children, said the study, published in the British journal Nature Neuroscience.
Using electroencephalographs, which measure neuronal impulses, the researchers examined activity in a part of the brain — the anterior cingulate cortex — that is strongly linked with the self-regulatory process of conflict monitoring.
