EDIT: Let’s cool it with the downvotes, dudes. We’re not out to cut funding to your black hole detection chamber or revoke the degrees of chiropractors just because a couple of us don’t believe in it, okay? Chill out, participate with the prompt and continue with having a nice day. I’m sure almost everybody has something to add.
IQ score is a sham - the tests are quite fallible, and historically they were used as a justification to discriminate against people who are poorer or with worse access to education. Nowadays, I see it quite a lot in the context of eugenics, where some professors and philosophers attribute poor people being poor due to their low intelligence (low IQ score), and that they can’t be helped while rich people got where they are due to their intelligence (as in they have a high IQ score on average).

In adults its well correlated with ability to learn and perform. If don’t care why and just want to hire the best candidate its a good test.
But it doesn’t necessarily show if they have common sense. If you have many low complexity problems then maybe, but it can’t predict the best performers
Not only that, but a lot of developmental disabilities are only recognized as needing accommodations if the person scores low enough on an IQ test. But many score high on these tests, but do poorly in school because they are stuck in a system that only values people who learn from lecture, repetition, and regurgitation. So they are considered lazy rather than needing help.
My favorite argument agents IQ is that every thing it claims “inherent quality”, “can’t be studied for” ect were exactly what the SAT used to claim.
