Tucson Festival of Books: Chris Mooney

Earlier today, The Range noted that I'll be moderating a panel of political writers—Rick Perlstein, Chris Mooney and Tom Zoellner—on Saturday at the Tucson Festival of Books. (You can get details here, but it's from 2:30 to 3:30 in Gallagher Theater and will be carried live on C-SPAN's Book TV.)

Mooney, the author of The Republican War on Science and the forthcoming The Republican Brain, writes about the intersection of politics and science—and how many scientific policy decisions are decided on the basis of politics and not science.

The Republican Brain explores how the way our minds work have a lot to do with how we approach politics. An excerpt from a recent Salon article that Mooney wrote about the book:

The idealistic, liberal, Enlightenment notion that knowledge will save us, or unite us, was even put to a scientific test last year—and it failed badly.

Yale researcher Dan Kahan and his colleagues set out to study the relationship between political views, scientific knowledge or reasoning abilities, and opinions on contested scientific issues like global warming. In their study, more than 1,500 randomly selected Americans were asked about their political worldviews and their opinions about how dangerous global warming and nuclear power are. But that’s not all: They were also asked standard questions to determine their degree of scientific literacy (e.g, “Antibiotics kill viruses as well as bacteria—true or false?”) as well as their numeracy or capacity for mathematical reasoning (e.g., “If Person A’s chance of getting a disease is 1 in 100 in 10 years, and person B’s risk is double that of A, what is B’s risk?”).

The result was stunning and alarming. The standard view that knowing more science, or being better at mathematical reasoning, ought to make you more accepting of mainstream climate science simply crashed and burned.

Instead, here was the result. If you were already part of a cultural group predisposed to distrust climate science—e.g., a political conservative or “hierarchical-individualist”—then more science knowledge and more skill in mathematical reasoning tended to make you even more dismissive. Precisely the opposite happened with the other group—“egalitarian-communitarians” or liberals—who tended to worry more as they knew more science and math. The result was that, overall, more scientific literacy and mathematical ability led to greater political polarization over climate change—which, of course, is precisely what we see in the polls.

So much for education serving as an antidote to politically biased reasoning.

What accounts for the “smart idiot” effect?
