The validity of general cognitive ability predicting job-specific performance is stable across different levels of job experience.

Decades of research in industrial-organizational psychology have established that measures of general cognitive ability ( g ) consistently and positively predict job-specific performance to a statistically and practically significant degree across jobs. But is the validity of g stable across different levels of job experience? The present study addresses this question using historical large-scale data across 31 diverse military occupations from the Joint-Service Job Performance Measurement/Enlistment Standards Project ( N = 10,088). Across all jobs, results of our meta-analysis find near-zero interactions between Armed Forces Qualification Test score (a composite of math and verbal scores) and time in service when predicting job-specific performance. This finding supports the validity of g for predicting job-specific performance even with increasing job experience and provides no evidence for diminishing validity of g . We discuss the theoretical and practical implications of these findings, along with directions for personnel selection research and practice.
