Facts?

Yeah, we heard of 'em. Boston Globe (07.11.10), via Hullabaloo:

"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."

How facts backfire

"In fact, they often became even more strongly set in their beliefs."

Really?
