The results, which are published in the journal Science, revealed significant differences in both responses, which corresponded with people’s political views. Those with “markedly lower physical sensitivity to sudden noises and threatening visual images” tended to support liberal positions, while those with strong responses tended to be more conservative.I have noticed an obsession with fear for some time now among leading conservatives. Weakness, especially showing weakness or fear is a cardinal sin. The world is a tough place, goes the thinking. So you'd better grow up quick and grow up mean, so your fists get hard and your wits get keen (a political philosophy with all the sophistication of "A Boy Named Sue"). Thus, the Bush/Cheney/Rove/Palin obsession with not "blinking" or "cutting and running," with issuing belligerent statements and making John Kerry seem "French," etc. It is a projection of their own weakness, something I was getting at (less scientifically than Science magazine) with this post from last week.
This would fit with the hypothesis that people who have more fearful responses to perceived threats are more likely to be conservative, while those who have weaker responses develop more liberal views.
