Hedonic treadmill — consumers adapt to each product size reduction and forget what the original amount was
The team argues that shrinkflation succeeds because of hedonic adaptation: consumers quickly adapt to the new, smaller size and forget the old baseline. Yesterday's 18oz box becomes today's normal, making the loss invisible.

Shrinkflation exploits a psychological blind spot — humans notice price changes but not quantity changes
Companies reduce package sizes by 5-15% instead of raising prices because consumers monitor prices but rarely measure quantities. A $4.99 box of cereal that shrinks from 18oz to 15.5oz is functionally a 16% price increase that most people never notice.
