Society is polarising thanks to social media, with its self-reinforcing echo chambers. Like/dislike buttons promote groupthink and demote comments from critical thinkers whose thinking doesn’t conform to whatever is popular. This makes group-thinkers more tribal and protective of their ideas, while critical thinkers feel ostracised and more defensive about their ideas. Everyone becomes more combative and unhappy.
