Simply, life is an IQ test.

In 156 American studies that have reported the IQ means of a Black and a White sample, the mean Black-White difference is 1.1 standard deviations (SDs), or about sixteen IQ points.

In 1980, the National Longitudinal Survey of Youth administered the largest and most carefully selected national sample of 6,502 Whites and 3,022 Blacks an IQ test and found a difference of 1.2 SDs.

An IQ gap of at least 1.1 SDs for American Blacks (average 24% White admixture) and Whites has been present for the entire 100+ year history of IQ tests. The gap between African Blacks and Whites is 2.0 SDs.

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.”

Intelligence measured in IQ is logarithmic. Each standard deviation higher indicates about double the level of intelligence. Therefore, someone with an IQ of 100 is twice as intelligent as someone with 85. Someone with IQ 115 is twice as intelligent as someone with 100.

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, male geniuses outnumber female geniuses 7-to-1. Female intelligence is packed much closer to the middle of the bell curve, whereas men’s intelligence has far greater variability. 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. This is contrary to every other race and every animal species.

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.
