Yale study concludes public apathy over climate change unrelated to science literacy

Are members of the public divided about climate change because they don't understand the science behind it? If Americans knew more basic science and were more proficient in technical reasoning, would public consensus match scientific consensus?

A study published today online in the journal Nature Climate Change suggests that the answer to both questions is no. Indeed, as members of the public become more science literate and numerate, the study found, individuals belonging to opposing cultural groups become even more divided on the risks that climate change poses.

Funded by the National Science Foundation, the study was conducted by researchers associated with the Cultural Cognition Project at Yale Law School and involved a nationally representative sample of 1500 U.S. adults.

"The aim of the study was to test two hypotheses," said Dan Kahan, Elizabeth K. Dollard Professor of Law and Professor of Psychology at Yale Law School and a member of the study team. "The first attributes political controversy over climate change to the public's limited ability to comprehend science, and the second, to opposing sets of cultural values. The findings supported the second hypothesis and not the first," he said.

"Cultural cognition" is the term used to describe the process by which individuals' group values shape their perceptions of societal risks. It refers to the unconscious tendency of people to fit evidence of risk to positions that predominate in groups to which they belong. The results of the study were consistent with previous studies that show that individuals with more egalitarian values disagree sharply with individuals who have more individualistic ones on the risks associated with nuclear power, gun possession, and the HPV vaccine for school girls.
