I was at a cafe in Romana when the idea came to me about the differences in brain size in different ethnic groups and in the history of the species. I had recently read a controversial article by an equally controversial Dane about the intelligence of the Nordics and the "stupidity" of the Southerners. In fact, he didn't tell them directly, but from his studies it appeared that blondes are not like in the banks with blondes, on the contrary. Unfortunately, man is an animal that adapts to the environment, which does what other organisms do in case of exposure to environmental factors, such as the cold. And, it's true, northerners have bigger brains than southerners, whites than blacks, Neanderthal man than modern man, but also the man of now 10000 than the current man, but with few exceptions, which is somewhat correlated with the lack of climatic changes during this period.
It is known that the height of some species increases from the Equator with increasing latitude. The sizes of individuals within the same species are correlated with temperature, in the growing ice ages (study cited in "The Civilization of Hunger"). Hormones certainly vary. The brain grows like any other organ under the influence of growth hormones, both before and after birth. More, these hormones also vary seasonally, and differences in brain development, reflected in pathology, appear in the temperate zone in humans, but also in other mammals.
But a bigger brain necessarily means more intelligence? Sure, not, because intelligence is something complex, difficult to evaluate. But more typically human psychic characters? Probable, and, some. But not others. Better behavioral control? Probable. But not necessarily better verbal skills and a certain type of creativity. Definitely more autism. Maybe more non-conformity, related to a better power of concentration. But this is always a good thing? Anders Breivik might have a very big brain, as have other famous serial criminals in history.
Careful, the last paragraph contains data from my theory, which I admit could have less politically correct consequences. (That is, it could be interpreted as such, although who can penetrate and make predictions about the minds of people who discriminate on such superficial criteria? They probably find something that suits them from any research and any theory. ) But be careful, she also says that other environmental factors can shape the brain after birth in various ways. It is very good that people are different, the problem is that people from other populations and other cultures are too little present with what they have to offer in culture, science, economy, precisely for reasons of discrimination, not least economic. I mention that I would adopt a girl from Ethiopia. And who wouldn't hire a secretary like Kim Kardashian's rapper? 🙂
