That is actually one of the most fascinating research findings of the 90s.
you are right and that makes you wrong ;-)
The early environmental deficit appears to be ameliorated with time and
exposure to more environment. Paradoxically, this leads to an increase in
heritability among adults (where h^2 is around 80%) over children, in whom
the narrow heritability of IQ scores is just under 50%.
So ... we do make up for our environment, which means that we end up
different in ways specified by our genes.
