The Incremental Contribution of Complex Problem-Solving Skills to the Prediction of Job Level, Job Complexity, and Salary

As work life becomes increasingly complex, higher order thinking skills, such as complex problem-solving skills (CPS), are becoming critical for occupational success. It has been shown that individuals gravitate toward jobs and occupations that are commensurate with their level of general mental ability (GMA). On the basis of the theory of occupational gravitation, CPS theory, and previous empirical findings on the role of CPS in educational contexts, we examined whether CPS would make an incremental contribution to occupational success after controlling for GMA and education. Administering computerized tests and self-reports in a multinational sample of 671 employees and analyzing the data with structural equation modeling, we found that CPS incrementally explained 7% and 3% of the variance in job complexity and salary, respectively, beyond both GMA and education. We found that CPS offered no incremental increase in predicting job level. CPS appears to be linked to job complexity and salary in a range of occupations, and this link cannot be explained as an artifact of GMA and education. Thus, CPS incrementally predicts success, potentially contributes to the theory of job gravitation, and adds to the understanding of complex cognition in the workplace.
