What studies ? What data ? David Bessis basically says that there are so few twins reared apart that scientists can't make definitive conclusions.

I don't understand why you are challenging me here?

Isn't your question exactly that addressed by the (admittedly too long) article? That the graph Paul Graham presented proving the dominance of inheritance wasn't based on any science or data?

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".
