The most reliable cure for confirmation bias is interaction with people who don’t share your beliefs. They confront you with counterevidence and counterargument. John Stuart Mill said, “He who knows only his own side of the case, knows little of that,” and he urged us to seek out conflicting views “from persons who actually believe them.” People who think differently and are willing to speak up if they disagree with you make you smarter, almost as if they are extensions of your own brain. People who try to silence or intimidate their critics make themselves stupider, almost as if they are shooting darts into their own brain.Eventually social norms will evolve to catch up to the technology, provided we don't devolve into TurboYugoslavia before then.
