Scientific Proof, Conservatives Live in Caves

You've no doubt seen the article, about a study by one David Amodio:

PARIS (AFP) - 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.

Of course, conservatives are rigid and inflexible, liberals are dynamic, good looking, and delicate butterflies often land on their shoulders. Now, who needed a scientist to tell us that? Anyway, the methodology:

"People often drive home from work on the same route, day after day, such that it becomes habitual and doesn't involve much thinking," Amodio explained by way of comparison in an e-mail.

"But occasionally there is road work, or perhaps an animal crosses the road, and you need to break out of your habitual response in order to deal with this new information."

And David Amodio measured brain activity and decided that lots was going on in liberals brains when they had to "break out of their natural response". What he doesn't explain is why it is usually the liberals who decide to drive down the shoulder rather than wait their turn in line like everybody else.

I'm sure any brain activity observed in conservatives was chalked up to conservatives' tendency to daydream about oil profits while driving. Here's a question: What political persuasion is David Amodio? Think he's a liberal, or is the man a progressive?
