Raven Progressive Matrices, I believe the most used IQ test today is not influenced by cultural knowledge. IQ has an amazingly high correlation with academic success and work success, see https://www.youtube.com/watch?v=jSo5v5t4OQM it is worthwhile
Wikipedia says that people with autism and asperger's outperform other people on Raven's tests. Most people view ASD individuals as seriously cognitively impaired and they are often seen as low IQ, so I have trouble with your assertion. It suggests that people the world sees as highly impaired whose lives typically are harder than average are smarter than the rest of us. This completely flies in the face of every definition I have ever seen for IQ as a general predictor of competence.
Wikipedia also says the answers for Raven's matrices have been leaked, making them useless as an assessment tool.
Popular culture stereotypes autists as being highly intelligent.
The very existence of autism calls into question our historical conceptualization of intelligence and IQ testing.
I have two ASD sons. They are very bright. They also have some serious personal struggles.
So, which is it? Does IQ measure general competence or does it measure something else? Because this latest twist in the conversation seems just ridiculous.
>Does IQ measure general competence or does it measure something else?
It's an Intelligence Quotient. It measures intelligence. No one said anything about "general competence", whatever that even means. I imagine intelligence is an important part of "general competence" though.
You are contradicting yourself.
We cannot measure intelligence, since we cant even define it properly (in a way that we attach a measurement unit ot it).
