Hi Bells,
What a bizarre way to present facts. Most people would be glad to get an author's own press release from his home college newsletter - anything to give you a little more insight into what the study means. From I what I can tell it looks like Berkman, Pacheco and Plutzer created a tidy set of backup documentation and went through press release to the Public Library of Science with their 2008 article, and it probably just took this long to get a slot in Science. In the mean time they published their book. Of course once that first press release went out, they were all over the web anyway. So now they're getting to double-dip on publicity, which is really great.
I learned some interesting things from this. It was the first ever national survey of teachers on the question of evolution. I like the way they imagined this from the beginning and executed it so flawlessly. What a gold mine of information that nobody else bothered to dig into. They look so meticulous, so squeaky clean. They got support from NSF, and used benchmarks from National Research Council.
I also had no idea that nearly 50% of the public think Adam and Eve were the first humans, appearing within the last 10,000 years or so. I thought Ussher had fallen by the wayside along with witch-dousing. It doesn't surprise me that about as many high school teachers think God "guided" evolution. I can remember classrooms of education majors, in my early university years, who were flaming fundamentalists, so I can attest to a degree of correlation.
In any case, this little trench that's been dug, that proposes that science is flawed because the high school teachers say so, is obviously non sequitur. It's just the opposite. They're fundies. They're conflicted. They want to avoid the fray. And a substantial number never covered evolution in college, as I recall. And, of course, high school teachers are the least likely to represent scientific authority anyway. The whole idea is so crazy. And on top of that are the crazy ideas that all the media are lying.
In any case I share your frustration, so I'm posting to you to acknowledge what you're saying. Also I would like to acknowledge Origin, James R and Hercules Rockefeller. They are always quick to argue from the position of sanity.
