Despite being Negroid in skin color, even the blackest Indians are often 100% Caucasoid in facial structure and hair texture
Popular stereoypes, as well as psychometric and historical data, had left me with the impression that South Asians were more intelligent than sub-Saharans. For starters, South Asians had left Africa. had created an arguably independent civilization and were part of the Caucasoid race. In addition, immigrants from India are overachievers in North America.
So imagine my surprise when I started noticing that Indians appear to have smaller brains than sub-Saharans. At first I didn’t notice this because HBDers like Rushton and Lynn would lump South Asians in with Caucasoids or Middle Easterners respectively, or just ignore them completely.
However an excellent data-set analyzed by Rushton showed that North Indian and South Indian men averaged 1305 cm3 and 1237 cm3 respectively. Splitting the difference, this suggests an Indian man mean of 1271 cm3. By contrast, West African men averaged 1339 cm3!
Of course given the extreme levels of malnutrition in 20th century India, the brain sizes are likely well below their genetic potential, however the same might be said for sub-Saharans.
Invoking notions of evolutionary progress, Rushton argued that sub-Saharans were the least advanced race because humans evolved in Africa, with non-African Sapiens emerging later in evolution. If so we’d expect Indians, who are arguably Caucasoid, to have bigger brains than sub-Saharans, but the opposite is the case. Was this another flaw in Rushton’s theory or could the paradox be solved?
Body Size
When I was in high school, an extremely muscular Indian classmate was dismayed that everyone thought he was black. I explained to him that it was because his physique fit the stereotype of black explosive strength and not the nerdy Indian stereotype the school had come to embrace.
Indeed, despite living in the developed World, a New Zealand study found Indian men were a colossal 1.94 standard deviations (SDs) smaller than White men as measured by fat-free body weight. To put that in perspective, the height gap was 1.16 SD and the overall weight gap was only 0.48 SD.
Source: Rush, E. C., Freitas, I., & Plank, L. D. (2009). Body size, body composition and fat distribution: comparative analysis of European, Maori, Pacific Island and Asian Indian adults. British Journal of Nutrition, 102(04), 632. doi:10.1017/s0007114508207221
Meanwhile, another study found black American men are 0.13 standard deviations heavier on lean mass than are white American men, but because black Americans are only about 75% sub-Saharan genetically, we should probably correct this figure for white admixture (0.13 SD/0.75) which increases it to 0.17 SD.
Source: Lean mass, muscle strength, and physical function in a diverse population of men: a population-based cross-sectional study by Andre Araujo et al .
Although fat-free mass (FFM) and lean mass (LM) are not quite the same thing and were not measured the same way in both studies, and although neither study directly compared blacks to Indians, by adding the Indian-white gap in FFM (1.94 SD) to the black-white gap in LM (0.17 SD), we should get at least a rough proxy of the Indian-black gap on measures of intrinsic size and that gap is 2.11 SD.
Now at least among soldiers of the same rank, the correlation (within race and sex) between cranial capacity and weight is 0.41 (Rushton 1992). Assuming the same within race correlation between cranial capacity and intrinsic weight (solders have low fat) among men in the civilian population, then a 2.11 SD gap in intrinsic weight predicts a 0.41(2.11 SD) = 0.87 SD gap in brain size. Since the within race SD for men’s cranial capacity is about 91 cm3, at least among enlisted soldiers (Rushton, 1992; inferred from standard error) then this predicts a brain size gap of 0.87(91 cm3) = 79 cm3.
In other words, if the average man in India (brain size = 1271 cm3 ) had as much intrinsic mass as the average West African man (brain size = 1339 cm3) his brain would increase by 79 cm3, making it 1350 cm3.
Paradox resolved!

There is some things to consider here before making up things out of the ordinary. The Indians on the New Zealand study are still comparatively shorter and lighter than other groups of people so they will have a lower fat free mass overall, however what needs to studied is their fat free mass to overall body weight ratio. The average Maori and Pacific Islanders are considerably overall larger than Indians in terms of overall weight and fat mass. Another thing that needs to be considered is that Indian people tend to be vegetarians regardless of being generational in New Zealand which doesn’t help their overall weight and fat free mass. A person directly from West Africa who eats meat will still have more fat free mass. Another thing to consider is that both Africa and India are diverse in general. Most Indians in New Zealand are from the Eastern parts of Indians. Now I do not have the statistics but from my experience. The recent Punjabi Sikhs here in Canada look significantly larger than even Indians directly from the Caribbean who have had access to much better diets compared to Indians directly from India. I have seen Punjabis in Canadian power lifting such as the lifter Inderraj Singh. I have not seen any Indo Caribbeans in heavy strength sports. These are Sikhs directly from India. It could be due to lactose tolerance. Same reason why West Africans look significantly bigger than East Africans despite both having black skin.
As for brain size, its probably how the brain is designed and the overall body to brain ratio that matters. Last time I checked, the Eskimos have some of the largest brains in the world but historically speaking, they have not shown many worthwhile accomplishments, no offense to them. When Christopher Columbus was sailing all across the world. He was not looking for the big head Native American Indians. He was looking for the smaller brained Indians in Asia. I see that Indians even have smaller brains compared to Middle Easterners in the study. However a good chunk of the Arab number system came from Indians whereas not much knowledge went vice versa. Another thing to take into consideration is that Einstein had a much smaller brain size too.
Even within India, its a stereotype that the darker skinned smaller head South Indians are smarter overall compared to North Indians.
From my experience, Indians do not tend to be mechanical kind of smart, they are more specialization kind of smart. They are good at math and vocabulary but they lack in organization and spatial abilities. I have noticed that Indians unlike East Asians and Europeans cannot build good organized well functioning cities with nice looking building but they seem to be good at using the limited resources they have and getting the job done. The Indian space program with a dirt poor budget managed to find water on the south side of the moon. Indians also tend to be better at business compared to East Asians. I have noticed Chinese people in Canada would open up one Chinese restaurant and the whole family works at that Chinese restaurant. They would also nickel and dime the black customers. I have seen Indian convenience store owners expand much more and they end up owning 15 convenience stores and they generally tend to let the black customers go if they’re a dollar short because Indians seem to look at the bigger picture in business whereas Chinese business owners care about even giving away free hot sauce packets. Indians however will over charge black customers and not label their products sometimes and they black customers would not even know it. I do not see Chinese doing shady business practices. They tend to charge you exactly the amount that is listed.
