Race and IQs

[The Grand Nudger]

You mean, if i took the test ten times..my score would only deviate 1 or 2 points?  That seems dubious.  

-and the differential in affluent and poor groups within the larger subset?  What does that look like?

No that's not what I meant.

For example, the mean IQ of the US is reported as 98 but it should be read as 98 +/- 1.

Then you didn;t answer the question, and it;s an instructive question.  Differences between individuals and groups can be consumed by a margin of error. Meh, moving forward-

Within -that- sub group of (largely) whites....is there any disparity between affluent and poor test takers?  How about the difference between an even smaller subgroup, african americans, and africans?  What does that look like? How about another subgroup? Differences between test takers with two white parents, one white and one black, and two black? How about two american, one american one african, and two african?

These are the questions, and these are the reasons that the "race scholar" is not considered credible. The research failed to account for disparities between geographic, cultural, and socio-economic factors that are known to effect test takers. Even if we lay aside the dodginess of "race".....it's not clear that the differences noted (if they arent consumed by margins of error) are actually measuring a difference in race, explicitly.
