Mostly because we have been dumbing down our kids for years. We rank not only so low in belief of a scientifically proven fact, but in most scholastic ratings as well. And the trend continues.
We have a population that also largely believes in alien abduction, Bigfoot, psychics, ESP, and ghosts. Look at the popularity of dipshits like John Edwards.
Even supposedly credible journalists buy into woo woo claims hook line and sinker. We all know Larry King is an idiot, Glenn Beck is a dufus, and Katie Couric couldn't think her way out of a wet paper bag. It feeds the total lack of critical thinking displayed by Americans.
You have the loudmouth morons like Ann Coulter that has never even cracked open an evolutionary biology book in her pathetic life (quick, someone give that dingbat a sandwich, I've seen better fed ethiopians). But dipshit kool aid drinkers like her have a forum. People actually buy he books and believe her uninformed rants somehow hold any validity whatsoever.
It doesn't help to have a jesus freak president. If the GIC (Guy In Charge) is in the thrall of a medieval superstition- and bends the constitution to push his mythology- it's an uphill battle to champion science and reason.
As much as I defend Bush for his stance on national defense, in virtually every other regard he's worthless as tits on a boarhog.
The simple fact is that LEARNING SCIENCE is hard. Believing in some unseen hand that is responsible for all things is easy. We are, as a population- lazy as fuck. People care more about what moron won on some reality tv show more than the reality of the world around them.
Add to this the amazing- AMAZING- ability for people to totally dismiss bizarre claims about one thing- yet totally believe equally fantasical claims about their sacred cow- the self delusion is there fo all to behold. (hence the second quote in my sig line)
People are scientifically illiterate in the US. It's pathetic. Part of it is the sheer laziness of people more wrapped up in tivo'ing the latest episode of 24, than actually educating themselves.
It's a direct corrolation that the more eduated about science one is, the less religious one tends to be. And it's no coincidence that the bible thumpers are attacking the SCIENCE in the schools by pushing their goofy creation myth. The more you can dumb down the people about science, the easier it is to make them believe whatever goofy claim your making.
Part of it is the fact that we have an administration that is simply hostile to science because it's little more than a theocracy.
The end result is a largely ignorant, superstitious population dimwitted compared to countries we think of as backward.......
To quote Dr. Phil Plait (the Bad Astronomer): "The only cure for this sort of thing is knowledge"
