It is widely accepted that intelligence is inherited by parents, people who developed for hundreds of thousands of years in different environments completely different are only different from the neck down? Come on. I could go into how before europeans arrived, Africans had no advanced form of a written language, how they had domesticated no beast of burden, ect.
Compared to Blacks, Whites' brains:
* are 7% larger (1438cc versus 1343cc)
* are 100 grams heavier
* have deeper fissuration in the frontal and occipital regions
* have more complex convolutions and larger frontal lobes
* have more pyramidal neurons
* have 16% thicker supra-grandular layer
* react faster on mental chronometry tests
* have 600 million more neurons (each carries about 600 billion synapses, which each carry one bit of cortical information)
Genes contribute to about 90% of the individual variation of brain size.
Blacks are the only racial group with no DNA from the large-brained Neanderthals, and also the only race without the derived form of MCPH1 microcephalin called haplogroup D which produces increased brain volume.
Black-White IQ Distribution (Google: racial IQ bell curve):
Blacks:
5% above 110 IQ
16% above 100 IQ
40% above 90 IQ
70% above 80 IQ
30% 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
So, the top 16% of Black intellectual elites are only as intelligent as the top 50% of Whites
The genetic distance between H.Sapien and H.Erectus is only 0.17, while the genetic distance between Blacks and Eurasians is 0.23. Therefore Blacks are more genetically proximate to archaic humans than to modern man (Whites and Asians).
For comparison, the genetic distance between Blacks and modern man is greater than the genetic distance between the common chimpanzee and the bonobo (0.103, or half the Black-White distance) and between the Gorilla gorilla and the Gorilla beringei (0.04, or 1/6 the Black-White distance). Thus, Whites and Blacks are more genetically distant than two different chimpanzee species, two different gorilla species, Eurasians and Neanderthals, and Eurasians and H.Erectus.
IQ distribution by race/ethnicity:
* Ashkenazi Jews = 115
* East Asians = 106
* Whites = 100
* South East Asians = 87
* Non-White Hispanics = 86
* American Blacks = 85 (average 24% White admixture)
* Middle East and North Africans = 84
* Sub-Saharan Blacks = 67 (Only 2% of Whites score this low)
* Australian Aborigines = 62
Sub-Saharan Africans never even created a written language. It was the White colonialists who gave the gift of literacy to them.
https://mattsjunk.com/blog/2017/5/12/wr ... -of-africaYeah first we gonna start with that bolded sentence right there, cause that's just a lie. I shouldn't expect much better though from a guy whose pride lies in his skin color, something he had no control over.
As for everything else you listed, you didnt prove that IQ is genetic. You only proved that there is a difference in IQ between different ethnic groups. People like myself argue that it is a result of social conditions and not genes. Some evidence of that is the existence of surprisingly low IQ scores in certain white populations. Under your theory, the average IQ in Serbia should not be 89. It should be at lowest in the upper 90s. And yet that isn't the case. Congrats on not proving your argument at all.
As for brain size, can you prove this affects black intelligence or are you grasping for straws again? And as for the number of neurons that you listed, I would suggest you read this study on environmental factors and neuron development:
http://www.urbanchildinstitute.org/arti ... evelopment
The least intelligent ten percent of Whites have IQs below 81; forty percent of Blacks have IQs that low. Only one Black in six is more intelligent than the average White; five Whites out of six are more intelligent than the average Black. These differences show in every test of general cognitive ability that anyone, of any race or nationality, has yet been able to devise. And they are reflected in countless everyday situations, “Life is an IQ test.â€
Further, only one-in-3.5 million (.00003%) African Blacks have an IQ of 140 or higher (genius level). But one-in-83 (1.2%) U.S. Whites is a genius. Therefore the per capita genius rate for U.S.-resident Whites is 41,000 times higher than it is for African Blacks.
The IQ distribution for US-resident Blacks having an average IQ of 85 and a standard deviation of 12.4 doesn't mean that there are no Blacks at all with IQs above 140; it means that only one Black in about 218,000 will have an IQ above 140. Meanwhile one-in-83 Whites have an IQ above 140. So given equal sized populations there will be about 2,600 times more White geniuses than Black geniuses. Since there are about 5.5 times more Whites than Blacks in the United States, White geniuses will outnumber Black geniuses by a ratio of about one-to-14,300. Therefore, if all the White people in the USA were replaced by Blacks having the IQ distribution of US-resident Blacks the number of geniuses in the country would fall from about 2.4 million to only about 1,000.
For every one gifted Black there are 8 gifted Whites, 80% of gifted Blacks are mixed race.
Incidentally, though the average IQ of East Asians is 6 points higher than the average non-Jewish White, the percentage distribution of East Asians with IQs above 140 is slightly lower. The reason for this is that the range of cognitive variation among Whites is greater than among East Asians. Specifically, Asians' IQs are more clustered around the mean; therefore, Whites produce more geniuses, but also more morons.
Psychometricians regard IQ tests as having high statistical reliability. A high reliability implies that although test-takers may have varying scores when taking the same test on differing occasions, and they may have varying scores when taking different IQ tests at the same age, the scores generally agree with one another and across time.
Standardized intelligence testing has been called one of psychology's greatest successes and is the field's most widely-used invention. Since standardized tests were first used to identify learning-impaired children in the early 1900s they have become one of the primary tools for identifying children with learning disabilities, they assist the military place new recruits, job screening and for evaluating professional athletes.
The scores on the SAT (especially the SAT-math) and the ACT are for all practical purposes interchangeable with IQ test scores. In 2005, 153,132 Black Americans took the SAT test. They made up 10.4 percent of all SAT test takers. But only 1,132 Black college-bound students scored 700 or above on the math SAT and only 1,205 scored at least 700 on the verbal SAT. On the math SAT, only 0.7 percent of all Black test takers scored at least 700 compared to 6.3 percent of all White test takers. Thus, Whites were nine times as likely as Blacks to score 700 or above on the math SAT. Only 0.16 percent of all Black test takers scored 750 or above compared to 1.8 percent of White test takers. Thus, Whites were more than 11 times as likely as Blacks to score 750 or above on the math SAT.
This gap is so significant that colleges give a "race bonus" of 230 points to Blacks, 185 to non-White Hispanics and penalize Asians by 50 points, all in an effort to help the low-IQ races gain admittance.
Studies also show there are some significant differences in what is called the structure of mental abilities. For example, if you took a sample of Black and White children, all of whom had scored around 100 on the WISC-R (the Wechsler Intelligence Scale for Children) meaning the Black kids in the sample were well above the Black average -- you would find significant Black-White differences on six of the thirteen subtests. The average Black child would do better on arithmetic and digit span; where the average White child would do better on comprehension, block design, object assembly, and mazes.
A person's level of moral reasoning is correlated with intelligence. Studies sequencing the stages of moral development support what we all know; you have to be cognitively mature to reason morally. IQ tests correlate with moral maturity.
There is also a strong correlation between IQ and success. Economists have started taking an interest in the value of human capital, particularly the factor that psychologists call cognitive ability. In other words, it’s the ability of a person to solve a problem most efficiently. Not with violence, but by thinking. It is worth noting here that Blacks possess 9.4 times more of the dysfunctional MAOA gene ("warrior gene") and have mean testosterone levels 19% higher than in Whites, both strongly correlated with impulsive, aggressive and violent behavior.
The farther north the populations migrated out of Africa, the more they encountered the cognitively demanding problems of gathering and storing food, gaining shelter, making clothes, and raising children during prolonged winters. Consequently, as the original African populations evolved into present-day Whites and Asians, they did so by hybridizing with Neanderthals which created larger brains and greater intelligence, but also slower rates of maturation, lower levels of sex hormones, and concomitant reductions in sexual potency and aggressiveness, and increases in family stability and social conformity.
When humans evolved from Blacks they hybridized with the large-brained Neanderthals 40,000 years ago in southern Europe. 37,000 years ago the gene that creates an increase in cranium capacity and a heavier, denser, and more developed brain appeared in humans, called MCPH1 microcephalin. Blacks are the only race without MCPH1 microcephalin.
The microcephalin and ASPM genes (which appeared about 8,500 years ago) are known to be involved in determining brain size and so far have no other known function.
Non-Black humans average 4% Neanderthal DNA. This is significant because there is only 1.5% difference between human and chimpanzee DNA. It is equivalent to having one Neanderthal great-great-great-grandparent. Blacks are the only race with no Neanderthal genes. Blacks also coexisted and interbred with archaic sapiens (H.heidelbergensis) for longer than those who left Africa. At least 30% of the Neanderthal genome made its way into non-Black humans.
Blacks are Humans 1.0; modern man evolved from Blacks and are Humans 2.0, the improved version. They were formed by hybridization with the large-brained Neanderthals which created larger, denser, more complex brains:
* Blacks = 2% Archaic admixture
* Whites = 4% Neanderthal admixture
* Asians = 5% Neanderthal + Denisovan
Pre H.Sapiens are Blacks; modern man (Whites and Asians) is hybridized with Neanderthal and is the improved version.
Sub-Saharan Blacks did not receive Neanderthal or Denisovan gene introgression, which is why Blacks are the most genetically distant of all the human races.
However, Blacks received significant gene introgression from other early (and unknown) hominid species, which the other races do not have because they left sub-Sahara before the introgression occurred. These early hominids remain "unknown" due to the simple fact that their DNA has not been retrieved nor sequenced, Only Neanderthal and Denisovan DNA have been, thus far.
Forensic scientists can determine race by cranium shape; Blacks have a small frontal lobe and sloping frontal plane and a smaller cranium-to-mandible ratio. Whites have the largest craniums, an almost vertical frontal slope and a massive frontal lobe. The Asian is very similar and also more evolved. It is the frontal lobe that separates our behavior most from the animals and is responsible for language and rational thought.
Blacks show primitive traits associated with lower primates, such as prognathism, which is the slope of the face from the forehead to the jaws. A protruding jaw is associated with a sloping forehead which indicates a smaller prefrontal cortex, the area of the brain that handles planning, inhibition and self-control.
Blacks have more robust cranial bones, simpler cranial sutures, a higher rate of unclosed sutures, a lower cephalic index, a higher rate of saggital keel, more post-orbital constriction, a more sloped forehead, more rectangular eye sockets, a wider nasal index, less nasal prominence, a higher rate of joined nasal bones, a higher rate of sub-nasal prognathism, a lower facial angle, the presence of the "Simian shelf", a more rectangular palate, larger and wider-apart teeth, fur instead of hair, less spinal curvature, shorter spinal length, a lower sacral index, and longer arms and legs.
At birth Africans have fewer cranial bones than Eurasians. The skull and other bones in Blacks are thicker and denser, even in the fetus, making them more difficult to break. The Black skull is smaller, with less space in the forehead, but proportionately more at the back.
Based on studies of brain weight at autopsy, endocranial volume of empty skulls, head size measurements by the U.S. military and NASA, and two dozen MRI volumetric studies Blacks' brain size is 7% smaller than Whites', and 8% smaller than Asians'. There is a correlation of brain size with IQ of about 0.40 and that these racial differences in brain size are present at birth. Genes contribute to about 90% of the individual variation of brain size.
In addition to brain size are differences in brain shape, fissuration, number of pyramidal neurons and supra-grandular layer thickness. The depth of fissuration is related to superior intelligence and the brains of Whites have deeper fissures in the frontal and occipital regions. The supra-grandular layer of Blacks' brains is 16% smaller than it is for Whites' brains.
The average human brain contains 86 billion neurons. Whites, on average, have 600 million more neurons than Blacks. Each neuron carries about 600 billion synapses, each of which carries, as a minimum, one bit of cortical information.
Further, this reflects what we observe in real life (including the large and persistent so-called "Achievement Gap"). People have made long-term observations of the different races and reached rational conclusions; the more White a society is the more prosperous, inventive and safe it is. 19 of the 20 poorest countries are sub-Saharan African (Haiti). In sub-Saharan Africa the only countries that could be considered successful were White-governed, (Rhodesia and S. Africa). To this day they still can't even feed themselves even though they lived alone in Africa, a vast continent with temperate climates and abundant resources, for 60,000 years. So they cannot blame racism, poverty, imperialism or anything else for their failures.
No pre-contact sub-Saharan African society ever created a written language, or weaved cloth, or forged steel, invented the wheel or plow, or devised a calendar, or code of laws, or any social organization, or formal religion, or system of measurement, or math, or built a multi-story structure or bridge or sewer, or infrastructure of any kind, and they never harnessed a river, or even drilled well or irrigated, or built a road or railway or sea-worthy vessel, they never domesticated animals, or exploited underground natural resources, or produced anything that could be considered a mechanical device.
The 41 nations of sub-Saharan Africa produce no more wealth than the tiny country of Belgium, which has only 1/45 the population. Of all of the regions economic production, White-run South Africa accounts for three-quarters. That Whites are only 8% of South Africa's population, it demonstrates how productive and industrious Whites are that so relative few can carry the load for so many unproductive Blacks. But a constantly A constantly dwindling number of Whites are at the mercy of a predatory welfare class and its possible they cant and wont carry the rest of the population. If things get worse for them, they will simply flee the country.
Sub-Saharan Africans have never made a contribution to the world. Blacks can only achieve either because they are mixed with White genes or because they reside in White societies. Blacks are unable to achieve within their own race because not enough of them are smart enough to build a sufficient infrastructure. If allowed to become too numerous they destroy previously-thriving and safe White cities.
This is why Blacks seethe with jealousy and hatred of Whites yet can't seem to stay away because they want what we create and maintain, no matter if they deserve it or not. They want our peaceful and clean neighborhoods, our law and order, our technology and science, our school systems, our inventions, the jobs we create, the food we grow, the transportation we invent, the entertainment we provide..... Blacks hate us but can't live without us. That's why they demand that we take care of them and give them special rights and privileges that we don't grant ourselves, just to compensate for their inability at living in a modern and technologically-advanced civilization.
