Education teaches us to argue better

Interesting:

The same effect has also been captured in relation to the myth that the healthcare reform bill empowered government “death panels.” According to research by Dartmouth political scientist Brendan Nyhan, Republicans who thought they knew more about the Obama healthcare plan were “paradoxically more likely to endorse the misperception than those who did not.” Well-informed Democrats were the opposite—quite certain there were no “death panels” in the bill.

The Democrats also happened to be right, by the way.

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?

For one thing, well-informed or well-educated conservatives probably consume more conservative news and opinion, such as by watching Fox News. Thus, they are more likely to know what they’re supposed to think about the issues—what people like them think—and to be familiar with the arguments or reasons for holding these views. If challenged, they can then recall and reiterate these arguments. They’ve made them a part of their identities, a part of their brains, and in doing so, they’ve drawn a strong emotional connection between certain “facts” or claims, and their deeply held political values. And they’re ready to argue.

…So are liberals “smart idiots” on nukes? Not in Kahan’s study. As members of the “egalitarian communitarian” group in the study—people with more liberal values–knew more science and math, they did not become more worried, overall, about the risks of nuclear power. Rather, they moved in the opposite direction from where these initial impulses would have taken them. They become less worried—and, I might add, closer to the opinion of the scientific community on the matter.

You may or may not support nuclear power personally, but let’s face it: This is not the “smart idiot” effect. It looks a lot more like open-mindedness.
