Context was already presented, you just ignored it. They score lower even at age 3 when parents have the same economic background.

I'll only do this once, since I try not to debate idiots.

The question still remaining: is the cause of the group differences in average IQ purely social, economic, and cultural? Or are genetic factors also involved?

To attempt a definitive answer, I teamed up with Arthur Jensen and together we examined ten categories of scientific evidence from around the world published since Jensen’s path-breaking 1969 paper.

We concluded that the genetic component in Black-White differences is even higher than we had initially thought—likely 80%. This conforms to the "default hypothesis" laid out in Jensen’s 1998 book, The g Factor—that, by adulthood, genetic and cultural factors carry the exact same weight in causing the mean Black-White IQ difference as they do in causing differences between individuals in IQ—about 80% genetic/20% environmental.

For each set of data we contrasted a hereditarian model (50% genetic/50% cultural) and a culture-only model (0% genetic/100% cultural). Our 50/50 model did not exclude environmental factors, but it did require they be concretely demonstrable. Although the evidence we reviewed provided strong support for the genetic component of the model, we were unable to demonstrate any environmental element. "

You DO know what that means, right?
