[I bookmarked this about six months ago, and then completely forgot about it, but it's awesome enough to deserve a mention despite its complete lack of currency.]

A neurobiological study out of NYU and UCLA has finally and conclusively demonstrated that liberals are smart and conservatives are stupid. (Though I may be oversimplifying.)

Exploring the neurobiology of politics, scientists have found that liberals tolerate ambiguity and conflict better than conservatives because of how their brains work. ...

Frank J. Sulloway, a researcher at UC Berkeley's [natch] Institute of Personality and Social Research, [said] liberals could be expected to more readily accept new social, scientific or religious ideas.

"There is ample data from the history of science showing that social and political liberals indeed do tend to support major revolutions in science," said Sulloway, who has written about the history of science and has studied behavioral differences between conservatives and liberals.
