There are idiots of all races. Deal with them as individuals instead of trying to paint a broad picture due to the limitations of your
And again, how do you define intelligence? I totally agree with you saying that it's more a question of environment than of genetics, but even if it was a question of genetics, you can't really define intelligence.

Exactly, and intelligence changes throughout a person's life. So how does one measure someone's intelligence if it will only change?
True, you'd also need to measure it on a regular basis during all the life of an individual.
You should find a way to define intelligence, then measure intelligence (not IQ, a good way) but then measure it like once every month or at least 5 or 6 times a year for 60 years before being able to start to make an assumption backed with scientific proofs.
