According to my research, the average IQ of a white American is 100-105.
"Dr. William Shockley is a professor at Stanford University in Calif.
Basically the following constitute his views after many years of
painstaking study and research.
Major Findings of Dr. Shockley:
* Historically, blacks have an I.Q. 15 points lower than that of the
average White. The difference is due to heredity and not environment.
*... People with the low I.Q. of '80 make up a majority of the prison
population of America. (Average White I.Q. is 105).
People with the low I.Q. of '80 make up a majority of the prison
population of America. (Average White I.Q. is 105)."
"...Asians have one of the highest average IQ's in the world. The
average Asian American IQ is approximately 120, whilst the Average
Caucasian American is approximately 100..."
"In the United States, what little discussion there is about racial
differences revolves around intelligence. Study after study has
consistently shown that the average black IQ test score is 15 to 18
points lower than the white average. It appears that the gap starts at
about 15 points in childhood and widens to as much as 20 points in
adulthood. The gap has remained unchanged for 70 years?ever since IQ
tests were first given to large numbers of Americans."
"Despite overlapping intelligence distributions, only 16 percent of
blacks have IQs of more than 100, the white average. Whites are six to
eight times more likely to have scores in the ?gifted? range of 135
and higher, whereas blacks are six to eight times more likely to have
scores in the ?retarded? range of 70 or lower. At the very highest,
genius level IQ scores, blacks are hardly to be found at all."
