If IQ can be improved through education, then you cannot use it to argue that lower IQ people cannot be educated to be better at STEM jobs as the parent was arguing.
Sure, I'll give you that IQ measures something. The question is, is that something relevant to the argument that you can only be competitive in STEM with a higher IQ and therefore many people cannot be educated into STEM careers? Does IQ make you better suited for those jobs, or does the training for those jobs cause you to score higher on IQ tests?
It's no shock that richer and healthier people do better in school. If you want to call that "IQ" then fine, but saying the correlation goes the other way is an extraordinary claim that requires extraordinary proof. Without proof that a higher IQ makes you richer and healthier rather than the other way around, then yes, it is entirely scientifically invalid. Especially if you're not exactly sure what IQ is actually measuring.
If the parent wants to argue that some people can never be trained in STEM careers because STEM careers require too high of IQ, I demand proof that this psuedo-science malarky is defined and that it is proven to be inherent and cannot be trained during the course of STEM education.
