The strongest bias in American politics is not a liberal bias or a conservative bias; it is a confirmation bias, or the urge to believe only things that confirm what you already believe to be true. Not only do we tend to seek out and remember information that reaffirms what we already believe, but there is also a “backfire effect,” which sees people doubling down on their beliefs after being presented with evidence that contradicts them. So, where do we go from here? There’s no simple answer, but the only way people will start rejecting falsehoods being fed to them is by confronting uncomfortable truths.
