I was wrong about the adoption studies.

Adoption Studies

In addition to prenatal environment, the studies also fail to control for social environment. ... dy#Results
table of the Flynn-effect corrected results, 3rd table under Results...
It's interesting that the adopted children had a larger drop in IQ from 7 to 17, but the average drop for the adopted non-whites ((55*12.2+12*4.9+21*7.7)/(55+12+21)=10.1) was equal the drop for the adopted whites (10.1). The drop was smaller for the adopted blacks specifically (7.7), which could be due to the decline with age in the effect of "pre-adoption variables".
According to the Wikipedia article, Loehlin suggested prenatal effects, noting that among the adopted interracials, 66 of their 68 biological mothers were white. You'll notice that this group's IQ was only below the adopted whites by 6 and 8 IQ points, whereas the adopted blacks were below by 20 and 18 IQ points, more than twice below at age 17 and nearly four-times below at age 7.

Suffice it to say, the adoption studies results were influenced by many non-genetic variables, and it shouldn't be surprising that the adopted blacks still scored lower on IQ tests.

I think there is no correlation between brain size and IQ level. If compare brains of whale and elephant with humans, ours is too small. But we have very high intelligence. I think some connections between neurons or some unknown factors determine intelligence.

The Worldwide Pattern of IQ Scores. East Asians average higher on IQ tests than Whites, both in the U. S. and in Asia, even though IQ tests were developed for use in the Euro-American culture. Around the world, the average IQ for East Asians centers around 106; for Whites, about 100; and for Blacks about 85 in the U.S. and 70 in sub-Saharan Africa.

although environment is the major factor in determining IQ, genes (ie as in bigger brains which contribute to some innate intelligence) play a small- but not empirical- role. do not forget that Asians scored 6 points ahead due to their lower and unrepresented sample of selected subjects and higher visuospatial intelligence, but very average to below average verbal intelligence (a cause most likely due to selective breeding). in any case, there are other factors that determine intelligence- social, emotional, rhythmic, and others- that are often neglected by researchers, making IQ tests less credible. in the end, the way one is raised and their level of nourishment and nurture are major contributors to their intelligence.

1. There's no such thing as a "black brain." So your brain size claim has no validity.

2. The 70 IQ claim for Africans is a well-known fraud.

The physical body's brain has nothing to do with IQ. It is the result of the Spirit fused with the body at birth. Remove the Spirit from the body and the body drops into a comma.

What is missing from the south african human speies is the absence of the Adam and Eve genes, the stablelising evolutionary genes for young spirits that are evolving on their assigned planets. Adam and Eve's Evolutionary Contribution was interrupted and time shortened.

Same with asiams - missing adamic genes. You will soon detect the Adamic Gene.

Negative force spirits can be detected by a minus level EM generation of energy. A spiritual-souil who has not betrayed belonging to God the Father and Mother measures in the plus level.

Islamics are not worshipping the four members of the Family of God, therefore, can never become Immortal. Those Islamics that murder will be returned to the early animal realm that allows them to lose their current memory and start over.

All animals are pre-human evolutionary biological forms. At this time the Spirit learns how to use eyes, ears, and keep the eventual biological cells function.

Never ge tazared, as it destroys your spirit's memory and in next life, autism or cells that do not function. Tazar your hard drive for proof. That much destruction to your own Spirit.
