Who gets what wrong?

My colleague Daniel Klein reports from the front:

…under the right circumstances, conservatives and libertarians were as likely as anyone on the left to give wrong answers to economic questions. The proper inference from our work is not that one group is more enlightened, or less. It’s that “myside bias”—the tendency to judge a statement according to how conveniently it fits with one’s settled position—is pervasive among all of America’s political groups. The bias is seen in the data, and in my actions.

And what do the “right-wing” thinkers get wrong?

More than 30 percent of my libertarian compatriots (and more than 40 percent of conservatives), for instance, disagreed with the statement “A dollar means more to a poor person than it does to a rich person”—c’mon, people!—versus just 4 percent among progressives. Seventy-eight percent of libertarians believed gun-control laws fail to reduce people’s access to guns. Overall, on the nine new items, the respondents on the left did much better than the conservatives and libertarians. Some of the new questions challenge (or falsely reassure) conservative and not libertarian positions, and vice versa. Consistently, the more a statement challenged a group’s position, the worse the group did.

A college education, by the way, doesn’t help much.  Here is another statement of the conclusion:

A full tabulation of all 17 questions showed that no group clearly out-stupids the others. They appear about equally stupid when faced with proper challenges to their position.

That’s a lesson David Hume would have appreciated.
