Race and intelligence is a controversial area of anthropology and
intelligence research studying the nature, origins, and practical
consequences of racial and ethnic group differences in intelligence
test scores and other measures of cognitive ability.[1]
Much of the evidence currently cited is based on IQ testing in the
United States. While the distributions of IQ scores among different
racial-ethnic groups overlap considerably, groups differ in where their
members cluster along the IQ scale.[2] Similar clustering occurs with
related variables, such as school achievement, reaction time, and brain
size, and the gap shows up before age 3 on most standardized tests
after matching for variables such as maternal education.[3] Most
variation in IQ in the U.S. occurs within individual families, not
between races. However, even small differences in average IQ at the
group level might theoretically have large effects on social outcomes.
For example, a randomly selected group of Americans with an average IQ
of 103 had a poverty rate 25% lower than a group with an average IQ of
100. Similar substantial correlations in high school drop-out rates,
crime rates, and other outcomes have been measured.[4]
Many hypotheses have been proposed to explain racial-ethnic group
differences in IQ. Certain environmental factors, such as childhood
nutrition, are thought to modulate IQ in children[5], and other
influences have been hypothesized, including education level, richness
of the early home environment, and other social, cultural, or economic
factors. The primary focus of the scientific debate is whether group IQ
differences also reflect a genetic component. Hereditarianism
hypothesizes that a genetic contribution to intelligence could include
genes linked to neuron structure or function, brain size or metabolism,
or other physiological differences which could vary with biogeographic
ancestry.
The findings of this field are often thought to conflict with
fundamental social philosophies, and have thus engendered a large
controversy. Media portrayal of the role of genetic and environmental
factors in explaining individual and group differences in IQ was shown
in a 1988 study to be misleading regarding mainstream expert opinion.
Some critics examine the fairness and validity of cognitive testing and
racial categorization, as well as the reliability of the studies and
the motives of the authors, on both sides. Some critics fear the misuse
of the research, question its utility, feel that comparing the
intelligence of racial groups is itself unethical, whether justified or
unjustified. For instance, the disparity in average IQ among racial
groups is sometimes mistaken for the idea that all members of one race
are more intelligent than all members of another, or that ranking group
IQ averages from "high" to "low" implies a moral ranking of races from
"good" to "bad" or an overall ranking of "superior" to "inferior". The
conclusion that some racial groups have lower average IQ scores, and
the hypothesis that a genetic component may be involved, have led to
heated academic debates that have spilled over into the public sphere

Dit behoort die probleem meer duidlik te maak.
http://en.wikipedia.org/wiki/Race_and_intelligence_%28Averag e_gaps_among_races%29
IQ test score gap in the US
2003 SAT results by race/ethnicity. Redrawn from College Board
statistics. College Board classifications are not homogeneous; for
example, "Asian" includes East Asians and South Asians; "White"
includes Jewish Americans and other Whites.
2001-2002 GRE results by race/ethnicity. Source: [2], Table A.2In
almost every testing situation where tests were administered and
evaluated correctly, a difference of approximately one standard
deviation was observed in the US between the mean IQ score of Blacks
and Whites. In the United States, the mean IQ score among Blacks is
approximately 85 and the mean IQ score among Whites is approximately
100; the mean IQ score of Hispanics is usually reported to be between
the mean Black and White scores (Herrnstein and Murray report a mean
"Latino" IQ of 89 in The Bell Curve). The mean score for people of East
Asian and Jewish descent is usually higher than the mean score of
Whites, but the extent of that difference is not precisely known.
However, several studies place the median IQ of Ashkenazi Jews (who
make up the overwhelming majority of American Jews) at approximately
one standard deviation above the mean for other Whites, with the
primary Jewish advantage in verbal reasoning and the East Asian
advantage primarily in spatial reasoning. In The Bell Curve, Herrnstein
and Murray report mean IQ scores for East Asians and Jewish Americans
of 106 and 113 (on a scale where Whites = 103), respectively.
Similar gaps are seen in other tests of cognitive ability or aptitude,
including university admission exams such as the SAT and GRE as well as
employment tests for corporate settings and the military (Roth et al.
2001).
