Why we are poles apart on climate change : Nature News & Comment: If anything, social science suggests that citizens are culturally polarized because they are, in fact, too rational — at filtering out information that would drive a wedge between themselves and their peers.
For members of the public, being right or wrong about climate- change science will have no impact. Nothing they do as individual consumers or as individual voters will meaningfully affect the risks posed by climate change. Yet the impact of taking a position that conflicts with their cultural group could be disastrous.
Take a barber in a rural town in South Carolina. Is it a good idea for him to implore his customers to sign a petition urging Congress to take action on climate change? No. If he does, he will find himself out of a job, just as his former congressman, Bob Inglis, did when he himself proposed such action.
