After 6 years of a President who puts "beliefs" ahead of facts, appeals to God to solve thorny policy problems, and openly consorts with extreme Christian fundamentalists, is it any wonder that the country has turned its collective back on scientific thought?
Part of it may be attributable to a public backlash against intellectualism. The Right Wing has carried out a very successful propaganda campaign to convince Americans to follow their guts rather than their brains. It's an act that Stephen Colbert's faux punditry pretty accurately lampoons, and when you're misleading folks for gain you certainly don't want them using their heads to question what's going on in the world.
Americans needs to wake up and realize that it's the religious right who want to make a monkey out of them. If they don't, they might just find themselves becoming the thing they most feared: a benighted theocracy.
