These beliefs don’t have a traditional evolutionary advantage, but as we progress there’s less evolutionary pressure to support the status quo. George Washington professor James Bailey says:

The difference in IQs wasn’t great — ranging from 6 to 11 points (standard deviations is typically 15). Participants who identified themselves as “very conservative” had an average IQ of 95, compared with 106 among the “very liberal.”

I’m patiently awaiting the release of the full article, to gain a better grasp of their methods and results. Until then, I can make myself seem smarter (and more elitist) by affirming my belief of liberalism and sexual exclusivity.
