It was Thomas Jefferson who said that an informed electorate is a prerequisite for democracy. Recent research, however, finds that being informed may not be as beneficial as we think. In 2010, political scientists Brendan Nyhan and Jason Reifler had two groups of people read articles about how Iraq had weapons of mass destruction before the U.S. invasion. One group then read an article correcting that information: the 2004 Duelfer report, which confirmed that the country had no such weapons. Of conservatives who read only the first article, 34% believed that Iraq had weapons of mass destruction before the invasion. But of conservatives who read both, that number climbed to 64%. Contradictory information didn't change their beliefs; it actually strengthened them.
