Is it me, or are there a lot of article trying to tie political orientation to personal habits or consumption choices? Apparently the messiness of my desk is a marker of my progressive politics. A recent New York Times article tries to make a link between maternal weight and political ideology arguing that heavy mothers produce more conservative offspring. A month ago I read about a connection between an individual’s startle reflex and their orientation towards more hawkish national defense policies.

This is all driven by the recent resurgence in genetic explanations for political behavior. While advances is DNA mapping explain part of the resurgence, It seems to me that our scholarship is also being driven by our increasingly polarizing politics. As we move into left and right tribes socially, we seem to be resurrecting essentialist arguments to explain the phenomenon. I suspect we’re asking the question “are liberals wired differently than conservatives” because we’ve had “Red America vs. Blue America” beaten into our heads for almost a decade. I hope this academic fad passes quickly into the night so I can go back to keeping a messy desk!
