Lottery winners were not happier, and the reason was not the money
In 1978, psychologists compared major lottery winners with control groups and found a gap in the numbers that has been bothering researchers ever since.
Philip Brickman, Dan Coates, and Ronnie Janoff-Bulman published their study in the Journal of Personality and Social Psychology in 1978. They interviewed twenty-two major lottery winners, twenty-two controls, and twenty-nine people who had been paralyzed in accidents.
The finding that stuck: lottery winners rated themselves no happier than the control group. More troubling, they took significantly less pleasure from ordinary events — eating breakfast, hearing a joke, receiving a compliment — than people who had won nothing at all.
The mechanism is not mysterious once you see it. Winning a large sum establishes a new baseline. Compared to that peak, ordinary pleasures lose their contrast. The coffee that would have been delightful now competes with a memory of euphoria. Meanwhile the brain adapts to the new income level until it simply becomes normal.
The researchers called this hedonic adaptation, and the study gave it a vivid face. It became the founding document for what positive psychologists now call the happiness set point — the idea that each person has a baseline mood to which they tend to return after major events, up or down.
This does not mean circumstances never matter. But it suggests that chasing circumstances — bigger house, better job, larger number in an account — is a strategy that has been tested, at scale, by people who succeeded at it, and was found to arrive roughly where it started.
