Mr Penguin alerted me to this interested article in Wired. As you would expect, in the US, Republicans are more likely to be sceptical about global warming than Democrats. Environmentalism has always been found more on the left than the right, and Republicans have more to lose from action that makes energy more expensive.
But college-educated Republicans are far more likely to be sceptics than their less educated political allies, while a college education makes a Democrat less sceptical. What is about the combination of education and right wing politics?
It’s quite strange, because in all other areas of life I can think of, conspiracy theories are more likely to be found at the loony left end of the spectrum. But in this one, the more educated a right winger is, the more likely they are to believe that the scientific establishment is holding something from them.
