Don't twin studies prove that environment doesn't matter for IQ?

Besides the fact that twins share the same prenatal environment, a polygenic trait like intelligence has more than one cause. Twin studies show that there is a genetic explain part of the variance in intelligence, there is also an environmental contribution. Moreover, the effect of genome and that of environment interact, and are not static throughout the life span (the relative contribution of one over the other changes the older you get)

It means that they received the same nutrients, hormones, etc, and all these factors have an enormous impact on how a person develops later in life.

It's almost entirely genetic, my family has been clockmakers for over 1000 years. My parent's acute neglect of me is a separate subject.

That's funny, because most IQ tests do not claim to accurately test above 130+. For instance, the WAIS-R, the most common adult IQ test, stops bothering to further classify past 130+ (very superior). You wouldn't be lying about your IQ on the Internet would you?
