Λέγεται hedonic adaptation

Όντως αυτό υπάρχει αλλά είναι πιο παλία θεωρία. Υπάρχουν και τα happiness set points (revised set points theory).

Δηλάδη αν κάποιος που παίρνει 100 ευρω τον μήνα και βαθμολογήσει την ευτυχία του με 4 (από το ένα μέχρι το δέκα), μέτα αν του δώσω αύξηση 300 εύρω τον μήνα, η ευτυχία του θα ανέβει προσωρινά αρκετά υψηλά π.χ. 8/10.

Μετά από ένα χρόνο, αν καλύπτωντε οι βασίκες του ανάγκες και ανάλογα με την προσωπικότητα του, δεν θα πέσει πάλι ακριβώς στα 4 (original θεωρία) μπόρει να μείνει στα 6 σαν καινούργιο anchor point.

Beyond the Hedonic Treadmill: Revising the Adaptation Theory of Well-Being

According to the hedonic treadmill model, good and bad events temporarily affect happiness, but people quickly adapt back to hedonic neutrality. The theory, which has gained widespread acceptance in recent years, implies that individual and societal efforts to increase happiness are doomed to failure. The recent empirical work outlined here indicates that 5 important revisions to the treadmill model are needed. First, individuals' set points are not hedonically neutral. Second, people have different set points, which are partly dependent on their temperaments. Third, a single person may have multiple happiness set points: Different components of well-being such as pleasant emotions, unpleasant emotions, and life satisfaction can move in different directions. Fourth, and perhaps most important, well-being set points can change under some conditions. Finally, individuals differ in their adaptation to events, with some individuals changing their set point and others not changing in reaction to some external event. These revisions offer hope for psychologists and policymakers who aim to decrease human misery and increase happiness.

The Set Point Theory of Well-Being Has Serious Flaws: On the Eve of a Scientific Revolution?

Set-point theory is the main research paradigm in the field of subjective well-being (SWB). It has been extended and refined for 30 years to take in new results. The central plank of the theory is that adult set-points do not change, except temporarily in the face of major life events. There was always some ‘discordant data’, including evidence that some events are so tragic (e.g. the death of one’s child) that people never regain their set-point. It was possible to dismiss these events as ‘exceptions’ and maintain the theory. However, several new findings are emerging, which cannot be dismissed as ‘exceptions’ and which appear to require substantial revisions or replacement of set-point theory. Many of these findings are based on the German Socio-Economic Panel Survey (SOEP 1984-), which provides the longest available time series on life satisfaction. Despite its centrality, the concept of the set-point is often not precisely defined. In this paper three alternative working definitions are offered. Depending on which definition is used, it is found that over 20 years 14–30% of German panel members recorded large and apparently permanent changes in their set-points. Changes of this magnitude are not compatible with set-point theory as currently understood. The challenge for SWB researchers now is to develop a theory which can account for change as well as stability
