Science behind these specific claims aside, it does match up with some people I've known.
Example: 22 year old, bright guy, finished college, with degrees in chemistry, and get this: library science and information technology. He says he loves information. He's also from an extremely conservative, tea-party town, surrounded by hyper conservatives, most of whom are outright racist and old-southern mentality.
Result: he thinks Obama is a mooslum, believes every new theory Birthers come up with, disbelieves global warming and even the mere possibility that it COULD ever be possible, and repeats anything he hears from GOP pundits and media verbatim without a lick of critical thinking.
After talking with him a fair bit about his hang-ups, the only conclusion I could draw is that regardless of his education, exposure to a real science, working with scientists, etc... his homebred reality tunnel is just too narrow. In order for him to accept that most of what he's repeating is bullshit, he would have to accept that everyone he knows, trusts, and grew up around is deluded, ignorant, and believes things that are actually harmful to society.
Plus, he definitely has the "conservative" / neophobic mindset, where he is afraid of most of the world outside the normality he grew up with.
Against all that, education and knowledge have lost the battle, at least for now. Maybe some day he'll crack.
