The determinants of happiness

Measures of mood happiness are increasingly used to assess the development and progress of nations. The limitations of this approach are, however, considerable. Within developed nations population happiness is quite resistant to change, despite major improvements in the objective standard of living. The reason, we propose, is that levels of subjective wellbeing are psychologically managed for each person, to be held around their genetically determined 'set-point'. This homeostatic management system acts to keep people feeling normally positive about them self, and so resists change. Thus, the search for 'happiness determinants' in the form of objective circumstances is often unrewarding in normally functioning samples. Due to homeostatic resistance, changes in objective variables will have weak effects on mood happiness. If large changes in mood happiness are found, they can be attributed to homeostatic failure and represent pathology.
