Instead of ushering a new era of truth-telling, the information age allows lies to spread in what techies call ‘digital wildfires’. By the time a fact-checker has caught a lie, thousands more have been created, and the sheer volume of ‘disinformation cascades’ make unreality unstoppable. All that matters is that the lie is clickable, and what determines that is how it feeds into people’s existing prejudices. Algorithms developed by companies such as Google and Facebook are based around your previous searches and clicks, so with every search and every click you find your own biases confirmed. Social media, now the primary news source for most Americans, leads us into echo chambers of similar-minded people, feeding us only the things that make us feel better, whether they are true or not.
