Why We Are Poles Apart on Climate Change

This brief “World View” essay published in Nature takes a critical stance against the pop-psychology claim (one increasingly prevalent in the media) that public controversy over climate change reflects limitations in human rationality. On the contrary, it argues, people are reacting too rationally to climate change information: because positions on climate change have become a marker of one’s group allegiances, it is in the interests of individuals to attend to information in a manner that promotes beliefs that help them effectively signal their commitment to the cultural group on whom their status and well-being most depends. To fix this problem requires breaking the link between facts on climate chnage and antagonistic cultural meanings. In sum, “It’s the polluted science communication envrionment, stupid!,” and not stupid people, that accounts for the difficult we are in.
