Why Do People Believe Stupid Stuff, Even When They're Confronted With the Truth?

The "backfire effect" helps explain how strange, ancient and kooky beliefs resist science, reason and reportage.

The Truth: When your deepest convictions are challenged by contradictory evidence, your beliefs get stronger.

In 2006, Brendan Nyhan and Jason Reifler at The University of Michigan and Georgia State University created fake newspaper articles about polarizing political issues. The articles were written in a way which would confirm a widespread misconception about certain ideas in American politics. As soon as a person read a fake article, researchers then handed over a true article which corrected the first. For instance, one article suggested the United States found weapons of mass destruction in Iraq. The next said the U.S. never found them, which was the truth. Those opposed to the war or who had strong liberal leanings tended to disagree with the original article and accept the second. Those who supported the war and leaned more toward the conservative camp tended to agree with the first article and strongly disagree with the second. These reactions shouldn’t surprise you. What should give you pause though is how conservatives felt about the correction. After reading that there were no WMDs, they reported being even more certain than before there actually were WMDs and their original beliefs were correct.

They repeated the experiment with other wedge issues like stem cell research and tax reform, and once again, they found corrections tended to increase the strength of the participants’ misconceptions if those corrections contradicted their ideologies. People on opposing sides of the political spectrum read the same articles and then the same corrections, and when new evidence was interpreted as threatening to their beliefs, they doubled down. The corrections backfired.

Once something is added to your collection of beliefs, you protect it from harm. You do it instinctively and unconsciously when confronted with attitude-inconsistent information.

Not surprising at all.
