Ummm - why, if they can survive in the bush better than city folks, would that mean that that is the *only* place they can outperform?

Anybody remember the Chitlin Test? It was from the 70's, I think, it was an "IQ" test that only poor inner-city folk could do well on, as it assumed their background knowledge rather than your standard educated rich person's. Like knowing that the top and bottom of dice add up to 7 (which as a Parcheesi player, I actually did know)...

I think my point was that intelligence tests only test the ability to take intelligence tests. I, though I am very smart, wouldn't survive in the bush even though I did grow up in post-colonial Africa!
