"Very conservative" folks show the most anti-Arab bias, but surprisingly only between "slight" and "moderate." Liberals show between "none" and "slight."
Interestingly, according to the Post, "Most of the people approached for this article declined to participate. Several prominent politicians, Republican and Democrat, declined to take the tests for this article. The aide to one senator bristled, "You think he is a racist!"
According to researchers, "There is likely a biological reason people so quickly make assumptions -- good or bad -- about others...The implicit system is likely a part of the "primitive" brain, designed to be reactive rather than reasoned. It specializes in quick generalizations, not subtle distinctions.
Hmmmm...who does that sound like, conservatives ("my way or the highway," "America Love it or Leave It!", "Good and Evil," "Moral Values") or liberals ("diversity is good," "the world is a complicated place," "shades of gray not black and white")?
Also, I think the comment on the "primitive" brain, also known as the "reptilian" brain, is very telling vis-a-vis Republicans and Democrats. According to an article in Common Dreams, "The reptile brain has a singular focus: survival. It doesn't think in abstract terms, and doesn't feel complex emotions. Instead, it's responsible for fight-or-flight, hunger and fear, attack or run. It's also non-verbal - you can stimulate it with the right words, but it operates purely at the level of visceral stimulus-response." Again, who does that sound like? Hint: conservatives, Republicans, Bush.
In contrast, the "mammalian brain," also known as the "limbic brain," handles complex emotions like love, indignation, compassion, envy, and hope. You know, the kind of emotions that Dubya -- and the whole Bush family, for that matter -- is deeply uncomfortable with ("dont put me on the couch," they say). You know, all that "touch feely," "girly man" stuff the Democrats love so much. :)
Finally, there's the neocortex, which rests over the limbic brain (which, in turn, sits atop the reptilian brain). The neocortex processes abstract thought, words and symbols, logic and time. In other words, all the things that Republicans hate and liberals love. Hence, "intelligent design," "creation science," and other "faith-based" programs being pushed by conservatives, while liberals remain generally "reality based."
In sum, what these tests prove is that we all have prejudices, but that there is a DIRECT CORRELATION between conservativism and level/extent of prejudice. Bluntly stated, the more conservative you are, the more prejudiced, and the more liberal, the less.
In other words, it's fair to say that "Republicans are Reptiles; Democrats are Mammals." Also not surprising, the Republicans are far more prejudiced, violent, intolerant, harsh, and warlike than Democrats. And we needed a bunch of social scientists and millions of tests to tell us THIS?
