http://psychologytoday.com/articles/index.php?term=pto-20061222-000001&page=2The most comprehensive review of personality and political orientation to date is a 2003 meta-analysis of 88 prior studies involving 22,000 participants. The researchers—John Jost of NYU, Arie Kruglanski of the University of Maryland, and Jack Glaser and Frank Sulloway of Berkeley—found that conservatives have a greater desire to reach a decision quickly and stick to it, and are higher on conscientiousness, which includes neatness, orderliness, duty, and rule-following. Liberals are higher on openness, which includes intellectual curiosity, excitement-seeking, novelty, creativity for its own sake, and a craving for stimulation like travel, color, art, music, and literature.
The study's authors also concluded that conservatives have less tolerance for ambiguity, a trait they say is exemplified when George Bush says things like, "Look, my job isn't to try to nuance. My job is to tell people what I think," and "I'm the decider." Those who think the world is highly dangerous and those with the greatest fear of death are the most likely to be conservative.
Liberals, on the other hand, are "more likely to see gray areas and reconcile seemingly conflicting information," says Jost. As a result, liberals like John Kerry, who see many sides to every issue, are portrayed as flip-floppers. "Whatever the cause, Bush and Kerry exemplify the cognitive styles we see in the research," says Jack Glaser, one of the study's authors, "Bush in appearing more rigid in his thinking and intolerant of uncertainty and ambiguity, and Kerry in appearing more open to ambiguity and to considering alternative positions."
This article is just fantastic not just for public people, but for ourselves. This paragraph is very telling as far as the temperament differences between liberals and conservatives:
Most people are surprised to learn that there are real, stable differences in personality between conservatives and liberals—not just different views or values, but underlying differences in temperament. Psychologists John Jost of New York University, Dana Carney of Harvard, and Sam Gosling of the University of Texas have demonstrated that conservatives and liberals boast markedly different home and office decor. Liberals are messier than conservatives, their rooms have more clutter and more color, and they tend to have more travel documents, maps of other countries, and flags from around the world. Conservatives are neater, and their rooms are cleaner, better organized, more brightly lit, and more conventional. Liberals have more books, and their books cover a greater variety of topics. And that's just a start. Multiple studies find that liberals are more optimistic. Conservatives are more likely to be religious. Liberals are more likely to like classical music and jazz, conservatives, country music. Liberals are more likely to enjoy abstract art. Conservative men are more likely than liberal men to prefer conventional forms of entertainment like TV and talk radio. Liberal men like romantic comedies more than conservative men. Liberal women are more likely than conservative women to enjoy books, poetry, writing in a diary, acting, and playing musical instruments.
I'm still reading it. Very interesting.
