Sometimes people won’t – or don’t – change their minds, even when they’re presented with evidence showing their views aren’t based in fact.

It's a term used to explain politics all the time. But it's something that not a lot of people really understand. Celeste Headlee and Adam Ragusea "Break It Down” with help from University of Georgia
