The group that wrote down five things they were grateful for each week ended up happier than the group that listed hassles, exercised more, and even slept better. Yet the effect sizes in later meta-analyses are humbler than the advertising. This series finale reads the three experiments of the original paper in order and sorts out what honestly remains — a small but cheap and safe intervention — along with the conditions that amplify the effect and how to keep the habit from going stale.
