I’d be curious to see that research that proves IQ test scores are correlated with workplace performance. All jobs or just some? How strongly correlated? How is workplace performance measured? Is it discussed in your book?
A good starting point might be this 2004 review by Schmidt & Hunter. It tabulates correlations of 0.23 to 0.58 between “general mental ability” and “supervisory ratings of job performance”, with the correlation increasing monotonically with a five-level rating of job complexity.
Edit: I should probably add Schmidt & Hunter’s note that those averages “are corrected for measurement error in the dependent variable and for range restriction but not for measurement error in the GMA measure; hence, these are estimates of operational validities, not construct-level correlations.”
