Its one of the great assumptions underlying modern democracy that an informed citizenry is preferable to an uninformed one. 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. Its this: Facts dont 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. The general idea is that its absolutely threatening to admit youre 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. There is a substantial body of psychological research showing that people tend to interpret information with an eye toward reinforcing their preexisting views. If we believe something about the world, we are more likely to passively accept as truth any information that confirms our beliefs, and actively dismiss information that doesnt. This is known as motivated reasoning.
