And wouldn't you know the left side is the Repug side and the right side the progressive side.
I'd actually expect the centrists to be left side thinkers and extremists to be right side thinkers. Whether you hate humanity because you're a green zealot or because you think Jesus is coming back to destroy us all you're not very rational.

The article title seems to be deceptive. If you read the title by the authors it seems to disagree with the article.
"Remarkably, those stimulated on the left side fibbed a great deal more, those on the right showed much more honesty."
More is far less than impossible.
