Adaptation level theory, proposed by psychologist Harry Helson, helps us understand how people perceive and adapt to changes in their environment.
This theory explains that individuals have a baseline, or average level, of happiness against which they compare new experiences.
When significant life events, like winning the lottery, occur, they temporarily boost happiness, but over time, individuals adapt and return to their baseline level of happiness.
This is why a windfall gain brings only temporary joy.
A person winning a large sum of money might experience an immediate surge in well-being.
However, as adaptation level theory suggests, this happiness doesn't last forever.
- People adjust their expectations and desires according to their new wealth.
- Their happiness levels stabilize back to their personal norm.
This theory is crucial in understanding why people do not experience long-lasting increases in happiness from major positive changes.
