**Blacks have dramatically lower IQ, even if 50% White genes mixed in!** ====== Unpopular fact: USA Blacks are retarded, and Genes prove why they are retarded in negro DNA on US soil! **Half of USA Blacks are RETARDED!** ============= This fact is from official American Association on Mental Retardation, http://www.aamr.org For US Negroes, who are from race-mixing for over 200 years far far smarter than African Negros, the US Blacks are very retarded ON AVERAGE still. Niggers forced the US medical definition of "Retarded" to be altered because OVER HALF of negros are born with retarded IQs. **In 1959, AAMD set the IQ threshold for mental retardation at < 85**. The (((civil rights movement))) of the next decade forced psychologists to rethink this boundary, because half the African American population fell below it! **In 1973, responding to this concern, AAMD (by then AAMR) changed the threshold for retardation from IQ < 85 to IQ < 70**. The boundary moved south by one standard deviation! The proportion of blacks below the threshold instantly dropped from about 50 percent to 12 percent. Subsequent refinements made it still more difficult to meet the criteria for retardation. When Binet in 1905 produced the first IQ test, it promised to revolutionize the diagnosis and treatment of mental retardation. A half century later it came under attack for reasons Binet could not have imagined. Could any of the pioneer psychometricians have foreseen Larry P. v. Riles (1979), a California class-action suit that focused on IQ testing of young black children? **The court held that IQ tests were not valid for African Americans**. It banned California from using the tests for placing black students in classes for the "educable mentally retarded" or equivalent categories on the grounds that the tests were biased. After a series of appeals, the district court ruled that no special education related purposes exist for which IQ tests could be administered to black pupils. Though only a California ruling, the case began a political assault on standardized testing that has spread beyond the IQ test to college entrance exams, promotional exams and more. http://www.lagriffedulion.f2s.com/retard.htm La Griffe du Lion Volume 2 Number 9 : September 2000 **Court Bans Use of I.Q. Tests for Blacks for Any Purpose in California State**: https://eric.ed.gov/?id=EJ368279 **THE POLITICS OF MENTAL RETARDATION: A TAIL OF THE BELL CURVE**: https://archive.fo/1mNdz Niggers are retarded because pure blacks have %0.00 percent neanderthal high-IQ genes. Every other human on earth has large amounts of Neanderthal genes, even asians, who got them from fucking Denisovans a few times in history. Not one Neanderthal DNA gene has ever been found in any 300 year old or older skeleton in Africa, ever! %0.00 percent neanderthal high-IQ genes! DNA is well proven to be source of 80% of IQ based on huge research studies.

Who says so? Not a 'scientist' again?
