The Greening of the American Brain - TIME

As it turns out, Inslee might well be right, because facts and authority alone may not shift people's opinions on climate science or many other topics. That was the conclusion I took from the Climate, Mind and Behavior conference, a meeting of environmentalists, neuroscientists, psychologists and sociologists that I attended last week at the Garrison Institute in New York's Hudson Valley. We like to think of ourselves as rational creatures who select from the choices presented to us for maximum individual utility — indeed, that's the essential principle behind most modern economics. But when you do assume rationality, the politics of climate change get confusing. Why would so many supposedly rational human beings choose to ignore overwhelming scientific authority?

Maybe because we're not actually so rational after all, as research is increasingly showing. ... Politicians never debate the physics of space travel after all, even if they argue fiercely over the costs and priorities associated with it. That, however, is the power of group thinking; for most conservative Americans, the very idea of climate science has been poisoned by ideologues who seek to advance their economic arguments by denying scientific fact. No additional data — new findings about CO2 feedback loops or better modeling of ice sheet loss — is likely to change their mind.

The bright side of all this irrationality is that it means human beings can act in ways that sometimes go against their immediate utility, sacrificing their own interests for the benefit of the group. (Indeed, every day over the past month and a half in the cities of the Middle East we have seen human beings irrationally risking their lives for their values.)
