Yet most (western) countries immigration policy is set on the opposite assumption - that personality traits (of which IQ is only one) are not heritable.
The caution and "well it's complicated" shouldn't run in only one direction.

This is something often said by white people who never had to deal with the many issues around migrating to Western countries, even though we have the entire history of eugenics and "scientific" racism proving the opposite.

That would assume that there are two equally valid opposing views here, and yet there is nothing here to back that up. Science doesn't run on "both sides"-isms.
So why does the opening of https://en.wikipedia.org/wiki/Heritability_of_IQ say "Twin studies of adult individuals have found a heritability of IQ between 57% and 73% with the most recent studies showing heritability for IQ as high as 80% and 86%."?
Is the mountain of research on the heritability of psychological traits so obviously 'nothing', you don't even have to bother giving a source for your claim?
And heritability doesn't mean what you think it does
