The Republican Brain: Why Even Educated Conservatives Deny Science -- and Reality

New research shows that conservatives who consider themselves well-informed and educated are also deeper in denial about issues like global warming.

This essay is adapted from Chris Mooney’s forthcoming book,  The Republican Brain: The Science of Why They Deny Science—and Reality, due out in April from Wiley .

I can still remember when I first realized how naïve I was in thinking—hoping—that laying out the “facts” would suffice to change politicized minds, and especially Republican ones. It was a typically wonkish, liberal revelation: One based on statistics and data. Only this time, the data were showing, rather awkwardly, that people ignore data and evidence—and often, knowledge and education only make the problem worse.

Someone had sent me a 2008 Pew report documenting the intense partisan divide in the U.S. over the reality of global warming. . It’s a divide that, maddeningly for scientists, has shown a paradoxical tendency to widen even as the basic facts about global warming have become more firmly established.

Those facts are these: Humans, since the industrial revolution, have been burning more and more fossil fuels to power their societies, and this has led to a steady accumulation of greenhouse gases, and especially carbon dioxide, in the atmosphere. At this point, very simple physics takes over, and you are pretty much doomed, by what scientists refer to as the “radiative” properties of carbon dioxide molecules (which trap infrared heat radiation that would otherwise escape to space), to have a warming planet. Since about 1995, scientists have not only confirmed that this warming is taking place, but have also grown confident that it has, like the gun in a murder mystery, our fingerprint on it. Natural fluctuations, although they exist, can’t explain what we’re seeing. The only reasonable verdict is that humans did it, in the atmosphere, with their cars and their smokestacks.

Such is what is known to science--what is true (no matter what Rick Santorum might say) . But the Pew data showed that humans aren’t as predictable as carbon dioxide molecules. Despite a growing scientific consensus about global warming, as of 2008 Democrats and Republicans had cleaved over the facts stated above, like a divorcing couple. One side bought into them, one side didn’t—and if anything, knowledge and intelligence seemed to be worsening matters.

Buried in the Pew report was a little chart showing the relationship between one’s political party affiliation, one’s acceptance that humans are causing global warming, and one’s level of education. And here’s the mind-blowing surprise: For Republicans, having a college degree didn’t appear to make one any more open to what scientists have to say. On the contrary, better-educated Republicans were more skeptical of modern climate science than their less educated brethren. Only 19 percent of college-educated Republicans agreed that the planet is warming due to human actions, versus 31 percent of non-college-educated Republicans.

For Democrats and Independents, the opposite was the case. More education correlated with being more accepting of climate science—among Democrats, dramatically so. The difference in acceptance between more and less educated Democrats was 23 percentage points.

This was my first encounter with what I now like to call the “smart idiots” effect: The fact that politically sophisticated or knowledgeable people are often more biased, and less persuadable, than the ignorant. It’s a reality that generates endless frustration for many scientists—and indeed, for many well-educated, reasonable people.

And most of all, for many liberals.

Let’s face it: We liberals and progressives are absolutely outraged by partisan misinformation. Lies about “death panels.” People seriously thinking that President Obama is a Muslim, not born in the United States. Climate-change denial. Debt ceiling denial. These things drive us crazy, in large part because we can’t comprehend how such intellectual abominations could possibly exist.
