I'm not a member of BI Prime (nor do I have any intention of becoming one), so I can't see what they use to justify that bullet point.
Even given studies that show a link, there's a big difference between requiring a minimum IQ of 85 to join the US Armed Forces (as mentioned in the Wikipedia article on Intelligence Quotient) compared to asserting a minimum IQ of 120 (or whatever) to be a software developer, as amosquito seems to be doing in their comment ("...massive IQ-based barrier to entry..."). Of course there has to be some floor of intelligence to perform the job—but I'd argue it's a lot lower than many in our field believe.
Interesting. Assuming the data is accurate (a big assumption, given the controversy and inaccuracy inherent to these discussions), "computer occs" has a range of ~90-130—well over half of the population. Of course, "computer occs" is quite a broad category...
>A growing body of research suggests general cognitive ability may be the best predictor of job performance.
I don't think there's any doubt between IQ and delivering business value. Some argue EQ is more valuable, but that doesn't mean IQ isn't important.
