Read an article in yesterday's Journal-Star about some local professors involved in matching up startle reflexes with political policy positions. Maybe this is why some of the political types are so immutable.
The Startle Reflex - Key to Your Politics - Time - 19 Sep 08
"The study, published in the Sept. 19 issue of the journal Science, involved 46 Nebraska residents with strong political convictions. Researchers examined the link between each participant's stated political views and his or her physiological response to a perceived threat in the lab. People with stronger measurable threat responses, the study found, tended to adhere to 'socially protective' political policies, or those that suggest more concern for preserving the social unit — for example, supporting the Iraq war and the death penalty but opposing abortion rights and gay marriage.
Researchers shied away from using labels such as conservative and liberal in their study, but they concede that volunteers who registered a heightened sense of threat also tended to subscribe to conservative attitudes. 'It's not that conservatives are 'fraidy-cats,' says Kevin Smith, a political science professor at the University of Nebraska–Lincoln and one of the study's co-authors. 'It's that people who support socially protective policies — which, yes, can be interpreted as people taking a conservative position on those policies — are more sensitive to environmental threat.'"
