Slate has run an interesting recent series on the realities of race and IQ, in reaction to the recent general censure of James Watson.
Some striking hard facts:
Average IQ among Americans of European ancestry: 103
Average IQ among Americans of Asian ancestry: 106
Average IQ among Americans of Jewish ancestry: 113
Average IQ among Americans of African ancestry: 85
Average IQ among sub-Saharan Africans: 70
Average IQ among Japanese: 110
To give some perspective, I have heard it said that a difference in IQ of 15 points or more makes people’s thought processes mutually incomprehensible.
The author, William Saletan, also points out that IQ has been pretty stringly linked to brain size. This tends to scotch the argument that it is an arbitrary or culturally-biased measure.
A grim reality, perhaps, but reality is reality.

Where are the North American Indians on this? Off the scale?
They don't do too badly. Around 90.
