Motivated Happiness: Self-Enhancement Inflates Self-Reported Subjective Well-Being

Three studies support the contention that self-enhancement motivation distorts self-reports of subjective well-being (SWB). Both individual differences in self-enhancement (Studies 1 and 2) and experimental manipulations of self-enhancement motivation (Study 2) predicted an increased likelihood of reporting SWB at unrealistically favorable levels relative to others-a "happier-than-average effect." Study 3a and 3b showed that both trait self-enhancement and experimentally manipulated differences in self-enhancement motivation also affected self-reports on established measures of SWB. Specifically, individuals prone to self-enhancement were more affected than low self-enhancers by the desirability of happiness when reporting SWB. The current studies suggest that reports of SWB are susceptible to the same self-enhancement biases that influence self-reports of other positively valued traits. Implications and recommendations for the measurement of SWB and the use of well-being data in policy decision-making are discussed.
