Search: Racial IQ Bell Curve

IQ by race:

         •   Ashkenazi Jews = 115          •   East Asians = 106          •   Whites = 102          •   Inuits and Eskimos = 91          •   South-East Asians = 87          •   American Indians = 87          •   Non-White Hispanics = 86          •   Koko (a western lowland gorilla) = 85          •   American Blacks = 85 (average 24% White admixture)          •   Middle East and North Africans = 84          •   African Blacks = 67 (only 2% of Whites score this low)          •   Australian Aborigines = 62          •   Kalahari Bushman = 54          •   Congo Pygmies = 54

Asian IQ scores cluster around the mean; thus, the cognitive variation among Whites produces more geniuses, but also more morons.

IQ studies are normed for every conceivable variable and have been confirmed on twins and trans-racial adoption studies, but the racial IQ gap persists, including on non-verbal tests such Raven's Matrices, digit span, and mental chronometry.

The American Psychological Association declares, "...large differences do exist between the average IQ scores of Blacks and Whites, and that these differences cannot be attributed to biases in test construction."

What we refer to as "Black" in America, and as depicted in the below graph, are mixed race (24% White admixture).

The latest and best evidence, using high-density genotype data, shows that the proportion of European ancestry in the Black American population is about 24% (Bryc, Durand, Macpherson, Reich, & Mountain, 2015).

African Blacks are 1SD lower in IQ; compare IQs between American Blacks who average 24% White admixture (IQ 85) to African Blacks (IQ 67).

Black-White IQ Distribution:

Blacks:                  5% above 110 IQ                  16% above 100 IQ                  40% above 90 IQ                  60% above 80 IQ                  40% below 80 IQ                  18% below 75 IQ                  10% below 70 IQ

Whites:                  10% above 120 IQ                  18% above 115 IQ                  27% above 110 IQ                  40% above 105 IQ                  50% above 100 IQ                  60% below 105 IQ                  35% below 95 IQ                  15% below 85 IQ

As the New York Times put it, "...the difference in IQ points between the groups is quite significant. It means that the top sixth of Blacks score only as well on IQ tests as do the top half of Whites."

The least intelligent 10% of Whites have IQs below 80 (low functioning); 40% of Blacks do.

Only one Black in six is more intelligent than the average White; five Whites out of six are more intelligent than the average Black.

Incidentally, Black female IQ is 2.4 points higher than Black male IQ. There are twice as many Black females as Black males with IQs over 120, and five times as many Black females as Black males with IQs over 140.

About 2.3% of Whites have an IQ of at least 130 (gifted), 20 times greater than the percentage of Blacks who do; only 0.00044% of African Blacks have an IQ over 130. 80% of gifted American Blacks have White admixture.

Geniuses by Race (IQ 140 or higher):                  •   African Blacks                 1:3,500,000            (0.000003%)           •   American Blacks             1:218,000               (0.0004%)            •   Whites                             1:83                        (1.2%)             

So, the per capita genius rate for Whites is 41,000 times higher than it is for African Blacks.  

If all Whites in America were replaced by Blacks, the number of geniuses in the country would fall from about 2.4 million to only 1,000.
