I think he's suggesting rather the opposite, that a person can become
"dumb" (by your standard) if his culture has different values and
imperatives and simply doesn't concentrate on the issues you find
important or indicative of "intelligence".
For example, quite a few years ago I read a thesis concerning "IQ"
tests. US, inner city kids (mostly blacks and latinos) were doing very
poorly on standard IQ tests. A researcher, I don't remember the name,
proposed that this was not the result of any generally lower
intelligence but of how the questions were being posed and he re-wrote
the IQ tests in street language and tested thinking skills with problems
that would be more familiar to an inner city kid and voila, the IQ
scores rose dramatically.
As a "control", when these "new" tests were administered to suburban
(usually white and oriental) kids, their scores dropped dramatically for
just like the inner city kids had been on the old tests, the suburban
kids were being faced with problems they had never confronted before, in
language they didn't fully understand...the test methodology (ie: the
test "culture") was making them look "dumb"...

Do you have a link to this study? I'd like to see the results. In any
case, I find intresting that researchers can develop good IQ tests for
parrots (no culture!) and have this kind of problem for humans.

If we really wanted to separate the genetic component of intelligence from
social effects, we would take a bunch of newborn kids from smart parents,
then assign them randomly to different families. Ten or twenty years later
we could check to see if the kids raised by 'dumb' parents also ended up
dumb, or ended up smart like their genetic parents.
Somehow I don't think we'll see this experiment done anytime soon.

I believe something has already been done with twins that for some
reason were separated at birth. If I'm not mistaken, I read about this
on Freakonomics. The conclusion is that genetics is the main
contributor to academic performance (explains 50% of the correlation)
with the second most influential thing being peer pressure.

Unfortunately no, this was some years ago...actually before wide spread
use of the internet. The article was, if I recall, in a Scientific
journal (I read a fair number of them) but I can't say whether it was in
"Science" or "Scientific American" or a Psychology journal...
