My guess is that being rich doesn’t make you more likely to be an idiot, just that that being smarter makes you more likely to realize how much you have to lose.

Organizations and collectives have every incentive to oppose Green opinions on AGW, that’s to be expected. Corporate entities are deliberately designed to operate in ways that promotes their own self-interest, not those of their members, or of society as a whole.

With individuals its a bit more subtle. It would be unfair to claim that people will always support their own welfare over that of the community. I am convinced that opposition to science is not necessarily naked greed or selfishness, that it is often quite sincere. Its just that people are more likely to believe policies which benefit them are also more likely to benefit the commonwealth. Its perfectly natural — its human nature.

Its not causal, its a correlation. It can’t be proven logically or experimentally, but it certainly is suggested by the statistics.
