>>11648737This kind of stupidity is why I hate intelligence discussions. People will always pull retarded claims out of their ass.
>gene expression for intelligence ranges between 40-60% depending on the circumstancesWrong. Intelligence is heritable to over 80%. Gene expression is even larger than that because gene expression is broader than heritability.

But of course you can pull off any number you want. Say, if you shoot someone in the head, intelligence becomes 0% genetic and 100% environmental. When you put everyone in a large prison so everyone has the same environment, suddenly intelligence is 100% heritable. All these relative terms make these discussions annoying because dumbfucks will always come up with stupid exceptions.
When I talk about how much intelligence depends on genes, I refer to a modern environment. The point is, you can lower intelligence but you can't really raise it. If you find a method to raise intelligence significantly, you will become a billionaire.
>>The level of iodine nutrition plays a crucial role in the intellectual development of children.Exactly. Intelligence is like height. If you have malnutrition, your height is stunted. If you get to a good diet before your development ends, you may recover some of the lost height. But you can't eat more to get taller, you will just get fat.

>evidence that specific trade-offs within intelligence can be done during adulthoodFirst of all, I wouldn't call memory intelligence. I'd consider them skills that you train. Like chess masters who can visualize multiple boards in their head, yet don't become better in any other task, even visualizing other stuff.
