Concept
Hedonic adaptation
Hedonic adaptation is the return to a baseline after gains and losses: a raise, a bigger flat or a new car produces a lift that fades as it becomes normal, and most losses fade the same way. Haidt calls acquisition a hedonic treadmill, because you run and stay in place, and notes the exceptions that do not fade.
Lottery winners and people paralysed in accidents are, a year on, closer to their previous happiness than anyone predicts. The mind adapts to its circumstances and reports the change, not the level. This is why the promotion fades in a month and why Gilbert's impact bias runs the way it does. The useful part of the research is the list of exceptions. People do not adapt to noise they cannot control, to a long commute, to lack of control over their work, to shame, or to conflict in close relationships; these wear rather than fade. And they do not adapt to voluntary activities with variety and engagement built in, exercise, learning, time with people they love, work that produces flow, because the challenge moves. Money above sufficiency and possessions fade fastest. Spend, therefore, on removing the conditions that wear and on the activities that keep paying, and expect anything bought to become invisible within weeks.
A real-life example
A couple in Istanbul move to a bigger flat with a ninety-minute commute. Two years on they are less happy: the flat faded in six weeks, the commute never did, and the football and Sunday dinners they gave up for it were the durable items. They move back near the metro.
How to use it
- 1Assume you will adapt to anything you buy, and budget its happiness accordingly.
- 2Find the conditions you have not adapted to, noise, commute, lack of control, conflict, and change those.
- 3Protect activities with variety and engagement; they are what keeps paying.
