George Monbiot of the Guardian on climate change and climate change sceptics and other fools:
"In 2008 the Washington Post summarised recent psychological research on misinformation. This shows that in some cases debunking a false story can increase the number of people who believe it. In one study, 34% of conservatives who were told about the Bush government's claims that Iraq had weapons of mass destruction were inclined to believe them. But among those who were shown that the government's claims were later comprehensively refuted by the Duelfer report, 64% ended up believing that Iraq had weapons of mass destruction.
There's a possible explanation in an article published by Nature in January. It shows that people tend to "take their cue about what they should feel, and hence believe, from the cheers and boos of the home crowd". Those who see themselves as individualists and those who respect authority, for instance, "tend to dismiss evidence of environmental risks, because the widespread acceptance of such evidence would lead to restrictions on commerce and industry, activities they admire". Those with more egalitarian values are "more inclined to believe that such activities pose unacceptable risks and should be restricted".
