Does IQ predict job performance? This is the verdict

As to what an IQ can be used to measure, a study on IQ and job performance was done in 2015 by the Applied Developmental Science Journal states that an IQ “has utilitarian value because it is a reasonably good predictor of grades at school, performance at work, and many other aspects of success in life.”

As for how IQ directly correlates to job performance, it’s an ever-evolving field. “Hundreds of studies prior to the 1970s,” says the Applied Developmental Science Journal, “reported low and/or inconsistent correlations between IQ and job performance.”
