"Among social psychology’s fundamental lessons is that people are profoundly affected by what other people think. In their desire to be upstanding members of their political tribe, people are pulled toward embracing the stances of their peers and loath to publicly disagree with them.

As a result, the actual degree of political polarization on climate change belief and support for climate policy is considerably less than people think it is. Environmental activists often seek to increase support for climate policy by convincing skeptics about the reality and urgency of climate change. But our studies suggest that climate policy gridlock is largely about exaggerating disagreement for the sake of disagreement."
