>Right, but only for retards.
Wrong. It works on everyone, smart or dumb.
Obviously motivation will affect different people differently, but it's well understood that offering rewards, especially monetary rewards for completing an IQ test increases people's motivation which in turn raises the IQ scores artificially.
>Also people on meth are more involved and focused, there is a study that shows modafinil boosts midwits the most while high IQ don't get much beyond alertness and focus.
Interesting. I've done a bit of online research and it seems you're correct, but with some caveats.
IMO the best explanation for why Modafinil doesn't impact high IQ as much as others is probably due to the Ceiling Effect, meaning most of the high IQ people have reach their ceiling, their max IQ imposed by their genetics.
>cultural / linguistic
It's more than just linguistic differences.
It's legitimately a difference in how cultures prioritize different subjects, or rather teach different subjects. Cultural practices do shape cognitive skills, which is the issue here.
The perfect example for this is how asian countries, especially China teaches math completely differently than in the West, using an abacus. The abacus, in particular, enhances spatial and numerical processing, which can give Chinese students an edge on certain IQ subtests.
It's also the basis for the stereotype that "asians are good at math".
But the broader issue is trying to make IQ Test "culture-free". Taking Western culture out of Western-made IQ test is pretty difficult.
It's almost impossible to make an IQ test that works for everyone everywhere, because there isn't equal access to education, to ressources like a library for example, access to the internet, access to good nutrition and so on.
Once again I'll use the example of the illiterate person who is still decently intelligent, but can't perform well on a written test because they can't read or write.
Socrates was illiterate, for example.
