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.
