This is a bit of an aside. I’m interested in the relationship between job performance and IQ, for reasons. However everything I read about it seems like a bag of snakes.
Much in developmental theory, and psychology in general, depends upon the validity of IQ tests.
In the absence of agreed construct validity this has weighed heavily on indirect validity using correlations with criterion outcomes among which job performance has a special status.
Hundreds of studies prior to the 1970s reported low and/or inconsistent correlations between IQ and job performance.
These correlations have been approximately doubled using corrections for supposed errors in primary results and combining them in meta-analyses. Such corrections have many strengths, theoretically, but are compromised in these cases by the often uncertain quality of the primary studies.
The corrections to sampling errors, measurement errors, and to range restriction have required making a number of assumptions that may not be valid and have created a number of persistently contentious issues.
The claim that the IQ-job performance correlation increases with job complexity is not born out in more recent studies.
A range of other—including noncognitive—factors could explain a correlation between IQ and job performance, and even constitute part or all of the enigmatic “general factor.”
There remains great uncertainty about the interpretation of IQ-job performance correlations and great caution needs to be exercised in using them as a basis for the validity of IQ tests and associated concepts.
I’ve not found a good rejoinder to this 2015 article, do you happen to know of one? I’ve not fully read these either, so researcher beware.
Work on figuring out how to raise IQ.
On topic, without a concrete model of what IQ is I would personally be skeptical of treating it like a metric, lest ye fall into ole Goodheart’s trap.
This is a good article that touches on the predictive power of IQ for life outcomes such as employment: http://ftp.iza.org/dp10356.pdf
Though I am skeptical of their conclusion that, since “adding grades and test scores to models with IQ and personality produces greater predictive power for the outcomes studied”, there is evidence that grades and test scores “capture relevant dimensions of human capability not captured by IQ and personality.” There are a lot of social aspects involved on how grades and test results can influence those outcomes.

Take for example this study suggests :
