Basehor, Kans.--Read The Republican Brain on the Republican Brain and laugh, weep, or scream.
For an even more nuanced approach, something that conservatives in general and Republicans in particular don't seem very capable of, watch a video of Jonathan Haidt's work.
As Justice Learned Hand once penned, "The mark of a free man is that ever-gnawing inner uncertainty as to whether or not he is right." And Julian Huxley, "To become truly adult we must learn to bear the burden of incertitude." This idea seems to be almost anathema to conservatives, who see the world in black/white, right/wrong, either/or, yes/no, my-way-or-the-highway terms.
Nonetheless, there's a lot of interesting science about how we're hard-wired for certain values. Given so many of the knee-jerk dismissals of scientific evidence by those on the right, however, the evidence will be hard for them to swallow. Which is even more curious, given the prevailing "just teach 'em math-'n'-science" attitude in the corporate world.
Teach kids science, but then politicize the scientific evidence and dismiss the findings when they don't agree with your pre-determined world view? And so it goes.
