Apparently many people are less rational than I thought was possible. Yes it seems when people are misinformed to support their ideology, correcting that misinformation actually makes them believe it more.

Now as crazy as it may seem, I think this does make a kind of sense. When two contradictory pieces of information are presented to a person, they will tend to believe the one they like the best. That is absolutely understandable, in a no duh kind of way. Now we combine that with another point. When somebody tries harder to convince a person their view is wrong, the person will think they are being lied to, in order to cover the truth. Those obvious observations combined, are exactly what this study finds. And it's the reason it's so hard to have people think across party lines.

So yah, it may look insane (and it is) when viewed in the larger picture, but it seems pretty obvious when you break it down. It still makes me shakes my head in disbelief.
