A wide survey of X (Twitter) posts has suggested that global happiness levels take about two weeks to rebound following a global crisis, or “shock”. Two events (the initiation of pandemic lockdowns and the invasion of Ukraine) were studied by surveying discourse on Twitter in the weeks before and after the event. The authors note that the results are a global average, and only represent people who: A. post on Twitter, and B. are from one of the surveyed countries (not including Ukraine or Russia). The study suggests that while people were more immediately upset by lockdown, it only took two weeks to rebound. The invasion caused less of a downturn in happiness, but it took longer for the mood to improve.
