The Smartest People Are Most Polarized On Climate Science

The people who deny climate science the most aren’t stupid, but actually are among the smartest, a new study confirms. Previous studies I’ve blogged about have documented this phenomenon, and now a new study in the Proceedings of the National Academy of Sciences documents the trend on a range of scientific — yet politicized — issues.

As E&E news summarizes [pay-walled]:

Looking at a nationally representative survey of views on stem cell research, the Big Bang, human evolution, nanotechnology, genetically modified organisms and climate change, researchers at Carnegie Mellon University found that respondents with the most education and the highest scores on scientific literacy tests had the most polarized beliefs.

On climate change, the researchers found that political identity was a more important signal of where respondents stood than their academic acumen or scientific sophistication.

“Conservatives with higher scores display less concern about climate change, while liberals with higher scores display more concern,” the authors wrote. “These patterns suggest that scientific knowledge may facilitate defending positions motivated by nonscientific concerns.”

The take-home point for advocates of climate action is that more facts won’t change people’s minds.  It’s not a question of ignorance that motivates this reasoning.  Instead, advocates should focus on new frames to address the challenge, as well as on specific facets of climate change that don’t require someone to accept all the science around it, like reducing air pollution or addressing sea level rise.

Essentially, climate change has become an issue of tribal identity and ideology — and no longer one of fact and reason.  While that’s disheartening, it’s also clarifying for understanding how to move forward on the issue.
