Oh, I saw that - the guy's argument is a bit of a whiny muddle, but the actual studies linked to are really interesting. I honestly wouldn't have expected such big differences in the apparent politics of different professions. Or, more accurately, different professors. I wonder what the politics of psychologists and psychiatrists in the US are like? (One comment I found suggested that fiscal conservatives might not be as keen on the starting salary of a professor after all those years of college!)
