Your comment mentioned "studies" plural.
There are many studies of twins that try to determine if genes influence intelligence.
Some look at twins who are raised together. One [1] concludes that "MZ (identical) twins differ on average by 6 IQ points, while DZ (fraternal) twins differ on average by 10 IQ points".

Yes? I mentioned them because the article was about a bunch of studies? I was asking the poster why you would not be interested in the validity of such studies and just decide that "common sense" was enough to make a decision?
The question was asked with genuine curiosity as this forum is mostly filled with people who appreciate science and empiricism. And I was hoping there could be a reasonable discussion.
But I'm out. An interesting discussion should be possible here purely based on data and statistics but clearly - from the downvotes - that I've stepped into some toxic American identity politic minefield.
I learned quite a time ago that it's risky to raise certain scientific subjects with USAians including my US relatives: biological evolution, the science of climate change, renewable energy or justifications for gun control - without the conversation getting emotional and heated. But I still find it weird.
