Abstract: To determine the relationship between Machiavellianism and job performance or career success, and explore the moderating effect of profession type as moderator variable to the relationship between Machiavellianism and job performance, this paper reviewed the related literatures systematically and quantitatively and carried out a meta-analysis on 45 literatures which meeting the accepted standards. The results indicated: (1)Machiavellianism is uncorrelated with job performance (r=0.008); When types of profession as the moderator variables, Machiavellianism is in low positive correlation with job performance for marketing professions (r=0.104) and in uncorrelation with job performance for general administrative professions (r= -0.030). (2)There is a low negative correlation between Machiavellianism and income (r=-0.063); (3)Machiavellianism is uncorrelated with position (r=0.007); (4)Machiavellianism is in negative correlation with job satisfaction (r=-0.130). As periodic summaries of study on Machiavellianism applied in workplaces, this paper provided the reference for the follow-up studies.
