The further people politically move from moderacy the more people lie

There is actually an interesting study that suggested that political extremists in the United States have higher IQs than their moderate counterparts.

When adjusted for race Democrats and Republicans have equal IQs, but when adjusted for moderates compared to those who identify as either extremely liberal or extremely conservative the moderates come up short by a statistically significant margin. Of course all these studies need to be read into to really understand them, but it is an interesting finding.
