It's been a hell of a decade for our species' intelligence: we've allowed an eradicated disease to return, let an algorithm convince us the earth is flat, and (essentially the same 2 points already mentioned), let fake news have the same look and feel as real news. We let democracy die. We let hard science prove the climate is on the precipice and then ignored the precipice. We let Gwyneth Paltrow sell snake oil, and then believed in the snake oil. We sold our hard-won science savvy by allowing the drunk moron at the end of the bar's opinion to have the same weight as the person who has been studying the subject for 25 years. Brian Cox: "Being an expert does not mean that you are someone with a vested interest in something; it means you spend your life studying something. You’re not necessarily right – but you’re more likely to be right than someone who’s not spent their life studying it.” My New Year's wish is this: let social media add a veracimeter to every 'news' article - a truth indicator for each article, based on links to credible sources, peer-reviews, hard science, real journalism. Then adjust everyone's feed to only display articles with a score over 90. Then ban anyone who posts any item with a score less than 60. Sorted! Happy 20's everyone!
