I haven't verified the data below contrasting blacks and whites, reported in the comments here. But I have heard these numbers enough, in enough places, to find them trustworthy.
IQ tests measure the innate and immutable mental capability that involves abstract thinking, logical reasoning, ability to solve novel problems and comprehend complex ideas.
Intelligence is inherited and not equally distributed among the races.
IQ by race:
• Ashkenazi Jews = 115
• East Asians = 106
• Whites = 100
• Inuits and Eskimos = 91
• South-East Asians = 87
• American Indians = 87
• Non-White Hispanics = 86
• 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 conducted on twins and trans-racial adoptions, but the racial IQ gap persists, including on non-verbal tests such Raven's Matrices, digit span, and mental chronometry.
No Black civilization has ever independently developed. No modern creations exist in sub-Saharan Africa that were not brought there by Whites. Without continuous intervention, Blacks cannot even maintain what Whites gave them.
19 of the 20 poorest countries are sub-Saharan African.
There are no White Third-World nations, but all Black ones are.
Highest National IQs:
• 108 Singapore
• 106 South Korea
• 105 Japan
• 105 China
• 102 Italy
• 101 Iceland
• 101 Switzerland
• 100 Austria
• 100 Netherlands
• 100 Norway
Lowest National IQs:
• 68 Somalia
• 67 Guinea
• 67 Haiti
• 67 Liberia
• 66 Gambia
• 64 Cameroon
• 64 Gabon
• 64 Sierra Leone
• 64 Mozambique
• 59 Equatorial Guinea
Blacks are proto-humans; modern man evolved from Blacks by hybridizing with the large-brain Neanderthals:
• Blacks = 2% Archaic admixture
• Whites = 4% Neanderthal
• Asians = 5% Neanderthal + Denisovan
Genetic distance is a measure of the genetic divergence between populations. Blacks have a genetic distance of 0.23 from Whites and Asians, but only 0.17 from Erectus. That means Blacks are more genetically proximate to archaic man than to modern man.
Blacks are the only race with no DNA from the large-brain Neanderthals. Civilizations didn't begin until the Neanderthal hybridization created the larger brains in modern man:
Brain Size by Race:
• Blacks = 1267 cm
• Whites = 1347 cm
• Asians = 1364 cm
Whites' brains are faster, larger, denser, and more complex than Blacks' brains:
• 7% larger
• 126 grams heavier
• deeper fissuration in the frontal and occipital regions
• more complex convolutions
• larger frontal lobes
• more pyramidal neurons
• 16% thicker supra-grandular layer
• one standard deviation more cerebrum
• react faster on mental chronometry tests
• 600 million more neurons
Whites are only 10% of the world's population, yet are the most industrious and innovative race the world has known. Whites unlocked the secrets of DNA, and relativity, launched satellites, created automation, discovered electricity and nuclear energy, invented automobiles, aircraft, submarines, radio, television, computers, medicine, telephones, light bulbs, photography, and countless other technological miracles. Whites were the first to circumnavigate the planet by ship, and orbit it by spacecraft, to walk on the moon, probe beyond the solar system, climb the highest peaks, reach both poles, exceed the sound barrier, descend to the oceans depths... yet Blacks still can't even feed themselves.
Whites have to provide food, medical, financial, and engineering aid to every Black nation. Blacks cannot survive without White charity. Blacks became an out-of-control invasive species after Whites domesticated them.
No pre-contact Black society ever created a written language, or weaved cloth, or forged steel, or invented the wheel, or plow, or devised a calendar, or code of laws, or system of measurement, or math, or built a multi-story structure, or sewer, or drilled a well, or irrigated, or created any agriculture, or built a road, or sea-worthy vessel. They never domesticated animals, or exploited underground natural resources, or produced anything that could be considered a mechanical device.
Blacks were still living in the Stone Age when Whites discovered them just 400 years ago.
Blacks are the oldest race, so they should be the most advanced — but they never advanced at all. Blacks lived alone in Africa, a vast continent with temperate climates and abundant resources for 60,000 years; so they cannot blame slavery, racism, colonialism, culture, environment, or anything else for their failures.
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:
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
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.
Incidently, 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 about 1,000.
The so-called "achievement gap" by SAT scores:
Year White Black Gap
1985 1038 839 199
1990 1031 849 185
1995 1052 857 195
2000 1060 859 201
2005 1061 863 197
2010 1063 855 208
2015 1047 846 201
This gap is so significant that colleges award Blacks 230 SAT "race bonus" points to help them qualify for admission. The Black-only National Achievement Scholarship was created because Blacks are not competitive for the National Merit Scholarship.
IQ by Race and Highest Degree Earned (1972 — 2014):
Highest Degree White IQ Black IQ Gap
High School Drop-out: 89 82 7
High School Diploma 98 90 8
Junior College Degree 102 95 7
Bachelor's Degree 108 100 8
Graduate Degree 113 102 11
Therefore, a Black with a graduate degree has an IQ equivalent to a White with a junior college degree.
Blacks can only achieve because they are mixed with White genes or because they reside in White societies. Too few of them are smart enough to even build sufficient infrastructure to allow the Black intellectual elite to achieve.
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."
