The science of social comparison and feed envy

Your brain measures 'how am I doing?' against other people — that's not a flaw, it's a 70-year-old finding. But the feed hands it a rigged sample: everyone's edited best moments, scrolled passively, thousands of times a day. Research shows people hide their negative emotions and we underestimate how common others' struggles are, so the scoreboard always reads 'everyone but you.' Here's what the studies actually found — and what happened when researchers changed the dose.
