The effects of personality on job satisfaction and life satisfaction: A meta-analytic investigation accounting for bandwidth–fidelity and commensurability

To what extent do employees’ personality traits shape their perceptions of job and life satisfaction? To answer this question, we conducted the largest meta-analysis on the topic to date, summarizing a total of 12,682 correlations among combinations of personality, job satisfaction and life satisfaction. We also sought to refine previous meta-analytic estimates by comparing the effects of personality facets to broad trait domains, while controlling for commensurability of personality measures. The results showed that the Big Five personality traits accounted for about 10% of the variance in job satisfaction, which in turn accounted for 13% of the variance in life satisfaction. Compared with the broad trait domains, personality facets typically accounted for twice as much variance in life satisfaction, with only a minor increase for job satisfaction, which contradicts the typical bandwidth–fidelity heuristic. The results also provided support for a trickle-down or top-down effect, where dispositions affect perceptions of life satisfaction, which then influenced the more specific subdomain of job satisfaction. The results have important implications for researchers and practitioners, suggesting that information is lost when personality facets are overlooked, and that educational and workplace interventions could enhance perceptions of satisfaction for those prone to lower levels of subjective well-being.
