^^ Pretty much this. IQ tests are extremely limited, not to mention largely culturally relative. There are notable limitations to an IQ test.
sure, but, if a person scores a 150, they are likely going to be pretty smart. They still might not be able to play well with others or not be able to pay attention to unimportant things like whether they left the stove on or not. And yeah, you can learn a lot from a dummy...I mean ahhh, someone with a low IQ score. It's certainly not "
largely culturally relative". Yeah, there may be some questions where the wording would favor middle class Americans over non-middle class Americans but there is no cultural limitations on 2+2=4 or "what will this box look like if it's unfolded?".
(unless you want to talk about how some cultures favor education and others discourage it, but that's a hole 'nother thread and not really one that can be fixed by changing how we measure intelligence or by the cultures that favor education explaining to the others why they should too)
