آیا افراد هوشمندتر شادترند؟ متاآنالیز روابط بین توانایی ذهنی عمومی و رضایت شغلی و زندگی

Despite folk and scholarly interest on the relationship between intelligence and happiness, there is an absence of cumulative knowledge on this topic to guide theory and practice. Accordingly, we conducted meta-analyses of the relationships of general mental ability (GMA) with two organizationally relevant indicators of happiness (i.e., job and life satisfaction). Drawing on the gravitation model and job design theory, we test a model that posits GMA has positive indirect effects on job and life satisfaction through the mediating effects of job complexity and income. Overall, the results of the meta-analyses showed that there was a small, positive correlation between GMA and both job satisfaction (ρ = 0.05) and life satisfaction (ρ = 0.11). The results of meta-analytic path analysis generally supported the hypothesized model. Further, there was an unexpected negative, direct relationship between GMA and job satisfaction. We discuss the implications of these findings for theory and practice.
