BASEHOR, Kan. - Conservatives have no monopoly on a "this is the way it should be" approach to life. Progressives certainly are no strangers to telling others how the world should be. My main point, expressed much more eloquently by Jonathan Haidt, is that progressives seem more open to asking questions, exploring new ideas, and challenging the status quo than conservatives are. And that conservatives seem more willing to engage in ad hominem attacks or Frank Luntz-type word play (death panels, traitors, socialists) when they decide they can't refute fact or scientific evidence.
When I was a freshman in college, my first scientific method professor hammered into us that there's no such thing as "proof," and that if a scientist used that word then, well, he really wasn't a scientist.
Scientists use the term "evidence," and "preponderance of evidence" to draw their conclusions and posit theories. Hence the "theory" of relativity and the "theory" of evolution, and, yes, the "theory" of human-caused global warming. The preponderance of evidence points in those directions, but there's no proof. But conservatives, who are so quick to throw stones at climate scientists, for example, over the supposed lack of evidence for global warming, are the same people who are willing to fight you if you question their version of a supreme being--for which there is scant/no scientific evidence. Hmmm.
I'm certainly the first to admit, and to use the words, "I don't know" when it comes to some of the complex issues facing us today. Would that more people use that as a starting point for dialogue and a search for evidence before spouting answers.
