Think of all those hardcore "greens" you may know ... the ultra-pious recycling, fossil fuel hating, global warming alarmist, finger pointing ninnies. You've likely got relatives like that. Or consider even the really genuine folks, those who simply believe that every shred of material tossed into the recycling bin saves the planet (and makes them feel better) and that every puff of exhaust is warming the climate; that all vitamins are good, oil companies are bad, and David Suzuki knows what he's talking about.
Then, consider the reaction of said folks when you challenge them with a few facts ... say, that global warming model forecasts are running way hotter than reality, or that global temperatures are massively adjusted in order to get a warming trend over the past 100 years. The zealots will usually toss in some shot about "oil company" propaganda, and the kinder gentler types will usually just ... glaze over. Sometimes, instead of a knowledgeable counter to your point, you may be referred to a webpage ... which will explain it all.
Yeah, generally, those who believe in dangerous man-made global warming ... or is it climate change ... no wait, I mean ACD, are generally pretty ignorant, with the zealots displaying a good dose of wanker.
So much for the theory that skeptics are dumb or uninformed. Fox News reports that a new study shows that when people are quizzed about climate science, the skeptics outscored the believers.
Dan Kahan at Yale did the study on 2,000 people, but with only nine questions, so there is limited insight here, but it fits with his previous study which found people who knew more about maths and science were more likely to be skeptical. Readers of skeptical blogs (who chose to respond to surveys and list their qualifications in comments) are likely to have hard science degrees. The world is slowly waking up to the fact that the skeptics are more knowledgeable about science.
