Also, contradicting the cultural bias or chitterlings explanation for low Black IQ are studies showing that Hispanics
(who on average are poorer than Blacks) and who have obvious language and cultural handicaps (many being new
arrivals to our culture), score significantly higher than Blacks in the abstract sections of IQ tests. They consistently
score higher in the verbal sections as well. American Indians, who in comparison with Blacks are poorer and generally
more isolated from mainstream American culture and education centers, also do better than Blacks on IQ tests. Arthur
Jensen in Bias in Mental Testing wrote:

On a composite of twelve SES [Socio-Economic Status] and other environmental indices, the American
Indian population ranks about as far below black standards as blacks rank below that of Whites … but it
turns out that Indians score higher than blacks on tests of intelligence…. On a nonverbal reasoning test
given in the first grade, before schooling could have had much impact, Indian children exceeded the mean
score of blacks by the equivalent of 14 IQ points … opposite from what one would predict from the theory
that ethnic group differences in IQ merely reflect SES differences.[73]

Blacks consistently do better on the parts of the IQ tests that have the largest cultural component and poorest on the parts that were the most culture-free. Blacks do far better on the verbal parts of IQ tests than they do on the parts with
symbols measuring abstract mental abilities. If cultural bias is responsible for differences in Black and White IQ scores,
then the biggest gap should be in the more culturally-loaded verbal tests. But the opposite is true.
