The Situation of the Climate Change Debate

Posted by The Situationist Staff on July 18, 2011

Situationist Contributor Dan Kahan, Maggie Wittlin, Ellen Peters, Situationist Contributor Paul Slovic, Lisa Ouellette, Donald Braman, and Gregory Mandel, recently posted their paper, “The Tragedy of the Risk-Perception Commons: Culture Conflict, Rationality Conflict, and Climate Change” on SSRN. Here’s the abstract.

The conventional explanation for controversy over climate change emphasizes impediments to public understanding: Limited popular knowledge of science, the inability of ordinary citizens to assess technical information, and the resulting widespread use of unreliable cognitive heuristics to assess risk. A large survey of U.S. adults (N = 1540) found little support for this account. On the whole, the most scientifically literate and numerate subjects were slightly less likely, not more, to see climate change as a serious threat than the least scientifically literate and numerate ones. More importantly, greater scientific literacy and numeracy were associated with greater cultural polarization: Respondents predisposed by their values to dismiss climate change evidence became more dismissive, and those predisposed by their values to credit such evidence more concerned, as science literacy and numeracy increased. We suggest that this evidence reflects a conflict between two levels of rationality: The individual level, which is characterized by citizens’ effective use of their knowledge and reasoning capacities to form risk perceptions that express their cultural commitments; and the collective level, which is characterized by citizens’ failure to converge on the best available scientific evidence on how to promote their common welfare. Dispelling this, “tragedy of the risk-perception commons,” we argue, should be understood as the central aim of the science of science communication.
