There’s nothing worse than arguing with someone who simply refuses to listen to reason. You can throw all the facts at them you want, and they’ll simply dig in their heels deeper.
Over the past decade, psychologists have been studying why so many people do this. As it turns out, our brains have glitches that can make it difficult to remember that wrong facts are wrong. And trying to debunk misinformation can often backfire and entrench that misinformation stronger. The problem is even worse for emotionally charged political topics — like vaccines and global warming.
