Numerous battles are being fought today within and across America’s political landscape, from global warming to the regulation of new technologies (e.g., GMOs, fracking). Science plays a big role in these debates, and as a result, social psychologists, political scientists, economists, and other social scientists have become interested in the question of why people (or rather, certain people) don’t accept scientific findings. These social scientists have converged on a concept called motivated reasoning: that because our reasoning powers are directed towards particular ends, we tend to pick facts that best fit our needs and motivations. Motivated reasoning, in this explanation, is a universal concept, perhaps a product of evolution; all human beings do it, including experts. It also raises the profoundly disturbing possibility of a scientific end to our Enlightenment hopes that experts—let alone publics—can be rational, that they can neatly separate facts from values and facilitate a harmonious society.
Influential science journalists have now started drawing on those findings. Chris Mooney, who made a name for himself writing The Republican War on Science, drew on social psychological and brain imaging research on political bias in a well-cited Mother Jones piece, “The Science of Why We Don’t Believe Science: How our brains fool us on climate, creationism, and the vaccine-autism link.” Other political scientists have written about this in high-profile outlets, such as Brendan Nyhan for the New York Times. It has also made several appearances on The Monkey Cage, a political science blog that is now part of the Washington Post. (read more...)
