Fact Free Discourse is Dangerous but Inevitable July 14, 2010

On this blog I have been persistently lamenting our political discourse in which facts play almost no role.  On issues from health care, to the causes of recession, to Obama’s citizenship,  outright lies seem to percolate to the top of our political discourse and endlessly circulate immune to challenge or refutation.

Recent political science research shows why, and it is discouraging for anyone who believes in democracy.

In the end, truth will out. Won’t it?

Maybe not. Recently, a few political scientists have begun to discover a human tendency deeply discouraging to anyone with faith in the power of information. It’s this: Facts don’t necessarily have the power to change our minds. In fact, quite the opposite. In a series of studies in 2005 and 2006, researchers at the University of Michigan found that when misinformed people, particularly political partisans, were exposed to corrected facts in news stories, they rarely changed their minds. In fact, they often became even more strongly set in their beliefs. Facts, they found, were not curing misinformation. Like an underpowered antibiotic, facts could actually make misinformation even stronger.

This bodes ill for a democracy, because most voters — the people making decisions about how the country runs — aren’t blank slates. They already have beliefs, and a set of facts lodged in their minds. The problem is that sometimes the things they think they know are objectively, provably false. And in the presence of the correct information, such people react very, very differently than the merely uninformed. Instead of changing their minds to reflect the correct information, they can entrench themselves even deeper.

“The general idea is that it’s absolutely threatening to admit you’re wrong,” says political scientist Brendan Nyhan, the lead researcher on the Michigan study. The phenomenon — known as “backfire” — is “a natural defense mechanism to avoid that cognitive dissonance.”

[…] This effect is only heightened by the information glut, which offers — alongside an unprecedented amount of good information — endless rumors, misinformation, and questionable variations on the truth. In other words, it’s never been easier for people to be wrong, and at the same time feel more certain that they’re right. […]

New research, published in the journal Political Behavior last month, suggests that once those facts — or “facts” — are internalized, they are very difficult to budge. In 2005, amid the strident calls for better media fact-checking in the wake of the Iraq war, Michigan’s Nyhan and a colleague devised an experiment in which participants were given mock news stories, each of which contained a provably false, though nonetheless widespread, claim made by a political figure: that there were WMDs found in Iraq (there weren’t), that the Bush tax cuts increased government revenues (revenues actually fell), and that the Bush administration imposed a total ban on stem cell research (only certain federal funding was restricted). Nyhan inserted a clear, direct correction after each piece of misinformation, and then measured the study participants to see if the correction took.

For the most part, it didn’t. The participants who self-identified as conservative believed the misinformation on WMD and taxes even more strongly after being given the correction. With those two issues, the more strongly the participant cared about the topic — a factor known as salience — the stronger the backfire. The effect was slightly different on self-identified liberals: When they read corrected stories about stem cells, the corrections didn’t backfire, but the readers did still ignore the inconvenient fact that the Bush administration’s restrictions weren’t total.

I don’t know what the solution to this is. But if we don’t find it quickly we will continue to suffer as a nation. The more we are dependent on technology and global connectedness, the more facts will matter in adjudicating disputes. We simply cannot afford to allow know-nothings to govern our discourse.
