Which is the best predictor of job success among the options?

• A. Integrity test
• B. General Cognitive Abilities Test
• C. Personality inventory
• D. Biodata

Answer: (B)

General cognitive ability is the best predictor because it reflects broad capacities for reasoning, learning, and solving new problems, which underlie performance across a wide range of tasks and roles. Tests of this ability consistently show the strongest association with job performance across many occupations, predicting both how well someone will perform tasks and how quickly they can learn new job requirements. The other measures tend to forecast narrower aspects of behavior or performance: integrity tests focus more on counterproductive behaviors, personality inventories predict tendencies like conscientiousness but usually with smaller links to overall performance, and biodata can be predictive but requires careful development and often adds incremental value rather than surpassing cognitive ability alone.
