> A good IQ test would be a good way to help our most promising children get the largest head start.
If that were true, then why are they not administered to every child? IQ tests appear to only to the potentially disabled and potential precocious. If a child is already showing signs of precociousness, then what would an IQ test present that was not already observed?
> It could help point out adults in your own company that have some type of potential.
I highly doubt adults at a company have hidden potential that is unknown. Underused? Sure. It's not like the companies have some sort of hidden genius that no one knows about. If one were a genius, it would have likely been apparent far earlier in their life.
> It could be used for scholarship purposes.
Do you really believe we should be awarding scholarships for meritless human attributes? Why not offer scholarships to other human attributes like height, weight, and beauty while we are at it?
That's thing about IQ, according to the research, it's like eye color, skin color, etc.. There isn't a damn thing one can do to change it (positively). So, I am not certain I am comfortable offering scholarships on raw IQ alone. In fact, isn't the entire purpose behind grades, standardized testing, etc.?
(Yes, I am aware the early SAT was a psuedo-IQ test, but that ended in the 80s or 90s, I believe. ACT was never truly comparable to my understanding.)
