hedonic

If not, you may be experiencing what psychologists call hedonic adaptation.

Hedonic adaptation is just a fancy label for what we already know: we get used to things.

Some have suggested that adaptation creates what might be called a hedonic treadmill.

Our conduct must be judged wise or foolish according as, in the long-run, we find a favourable "hedonic" balance-sheet.

The hedonic cannot, according to them, pretend to universal validity, it cannot be normative.
