r/K Selection Theory Rebuttals
The other day Anonymous Conservative (AC) published an article titled Criticism Of r/K Theory In The Comments. I’m not too worried about what he wrote in the main article (I may tackle that later if I feel up to it), but what I am worried about is someone’s critique of my article r/K Selection Theory: A Response to Anonymous Conservative. Since this guy uses AC’s writings who, of course, is influenced by Rushton’s application of r/K to humans, it shows that he’s pretty clueless about 1) the theory as a whole and 2) the theory’s ultimate status in biology. (Also check out Phil’s comments in the AC thread.)
The individual in question, one ‘Samuel Skinner’ calls my critique of AC “genuinely bad” and that he would “cover the most obvious mistakes“, well let’s take a look at my ‘genuinely bad‘ critique to AC.
RR: You don’t get it. Mongoloids being r-selected is straight from Rushton. He asserts that they have cold-adaptations. Cold adaptations are due to cold weather. Cold weather is an agent of r-selection (temperature extreme).
Samuel Skinner: Mongoloids have a variety of genetic adaptions to cold. If you drop one buck naked in the winter, they will still freeze to death. The actual adaption they have is wearing thick clothing covering the entire body, something that is both K and not existent in Africa. Needless to say knowing how to gather materials, make clothing and maintain it is a K selective pressure.
So “the actual adaptation they have” is to “wear thick clothing“? This is bullshit and you know it. I covered human physiological adaptations to the cold last month: Human Physiological Adaptations to Climate. Clothes weren’t made in Africa? “Knowing how to gather materials, make clothing and maintaining it” is not a “K selective pressure“.
RR: Endemic (native) disease is an agent of K-selection. Since the disease is constant, then the population under that agent of K-selection can prepare ahead for disease.
Samuel Skinner: That requires the preparation to actually work; if preparation has less effect on genetic pay offs then having children faster, having children faster wins.
The preparation does work. In the case of malaria (an endemic disease), one-fifth of patients use traditional malarial remedies in malaria-stricken countries (Wilcox and Bodecker, 2004).
Endemic and infectious disease is an agent of K-selection:
(From Anderson, 1991: 53)
RR: Do groups not work together in Africa to reach common goals? In the Pleistocene as well? Citations? Think before you write (and cite), because hunting bands in our species began with Homo erectus.
Samuel Skinner: NPC talks about clannishness and IQ difference in other posts. So he does believe that groups in Africa do not work together to reach common goals. I’m honestly not sure what he is thinking here.
Yes I do. But to say that ‘Africans don’t work together’ is stupid because Africa is a huge continent. Which African ethnies? Etc. And that’s also an incorrect claim.
RR: Density-dependent pressures are things such as endemic disease in Africa—which is necessary for a K-selected history since density-dependent natural selection occurs at or close to the environmental carrying capacity
Samuel Skinner: Yes, if a disease is transmitted through person to person contact and non-discriminatory. Malaria is transmitted through mosquitoes; the amount adding additional people increases its rate is negligible.
“This therefore provides empirical confirmation that sex ratio has an immediate impact on transmission success and that it is density-dependent” (Mitri et al, 2009). Endemic disease (like malaria) work in a density-dependent fashion (Anderson, 1991: 51).
Here is what people like Samuel Skinner and AC don’t get: r/K selection theory WAS discarded; it is no longer in use. Age-specific mortality better explains these trends than r/K selection (Reznick et al, 2002: 1518). I’ve also covered how the so-called ‘unidimensional construct’ or r on one end and K at another is wrong: “It appears that the original HKSS items are best represented as four distinct but related dimensions, and do not represent a unidimensional construct. This conclusion is reinforced by relationships between HKSS total scores and life history measures: The significant correlations that were found were contrary to the predictions made by the Differential K literature (Figueredo et al., 2013; Rushton, 1985). We found that high K scores were related to earlier sexual debut and unrelated to either pubertal onset or number of sexual partners. This suggests that the HKSS does not reflect an underlying “K dimension” (Copping, Campbell and Muncer, 2014).
It truly is tiring rebutting the same old bullshit arguments on r/K theory. I see AC’s bullshit on Twitter when I search ‘r/K Selection Theory’, but the individual who pushes the bullshit will not accept my invitation to come to this blog and discuss it with me.
The most important thing to know here is that the unidimensional construct that Pianka (1970) formulated is wrong. Joseph Graves (2002) reviews some of the literature on the theory, showing that Pianka’s (1970) verbal theory is wrong, and that r/K selection fell out of favor in the late 70s. It’s worth noting that Pianka gave NO experimental rationale (Graves, 2002: 135) to his unidimensional construct (which Copping, Campbell and Muncer, 2014). Do you see how this theory holds no weight in evolutionary biology anymore?
Samuel Skinner also says: “So they changed the name and kept some of the components. If the components they dropped are ones AC is using, say so.”
Here is what Reznick et al (2002) write:
Although life-history theory has shifted away from a focus on r- and K-selection, the themes of density-dependent regulation, resource availability, and environmental fluctuations are integral to current demographic theory and are potentially important in any natural system
I see the term density-dependent regulation, which I do not see on AC’s blog (the only thing that comes up if you search that term on his blog are the responses to me… that should tell you something). In regards to resource availability Reznick et al (2002: 1517) write: We have also found a potential role of resource availability, either as a consequence of environmental factors that are correlated with, but otherwise independent of predators, or as a consequence of indirect effects of predation (Reznick et al. 2001)”. If I were you I’d read some of the literature on this before writing more bullshit.
Skinner also writes: “Again, not following. The link between fertility and disease is pretty clear- after a die off the population rebounds. If a population is near carrying capacity and suffers a die off, the growth rate of the survivors increases.” Except African populations have had much more time to reach their environmental carrying capacity and to experience the K-selected agents of natural selection, like endemic disease (Anderson, 1991: 59).
Then AC jumps in and writes: “You cannot take a Biology 101 class without learning about r/K. It is in the textbooks, and it is seen as an excellent theory, akin to Newtonian Physics. Sure relativity and Quantum Mechanics came along and showed that Newtonian physics wasn’t the entire ball of wax. But you still learn Newtonian Physics, because it is fundamental to understanding everything else.” This, again, is bullshit. AC, have you taken a Bio 101 class? I took one. Not one mention of this discredited theory, I have an in use biology textbook (Understanding Biology, 2nd edition, Mason et al, 2017; check pages 905-908 in the textbook to verify this) and in the section on reproductive strategies (which is what r/K selection theory is, at its core) r/K selection is not mentioned once. Why make claims that you know you cannot verify?
AC: “What we are doing here is not something where you can point to a single old study, and say, here it all is, in one place. Bringing all this together is new, even if what is being brought together is well established.“
That doesn’t mean it’s right.
AC: The issue is, you have one area of study of humans (political science) where it is long established that humans spontaneously diverge into two groups, which the literature has recognized are so divergent that they call them Left and Right, as in each points in the opposite direction.
So stop dodging me and answer this question: Are liberals and conservatives local populations? If so, where did they evolve?
AC: “Now I know you didn’t read the book because you are hung up on the use of the phrase “r/K Theory.” In the book there is a chapter devoted to that. I use the meme of r/K Theory for the same reason it is taught in biology – it is a quick way to bring people up to speed on the purposes of these traits, and how they affect reproduction/survival under different conditions.”
Don’t worry; I’ll read your book soon enough and will probably have tons of material to rebut. Anyway, using discredited bio theories isn’t a good way to push something.
AC: “If it is done right, this will ultimately be a massive field of study with thousands of biologists and political scientists taking it apart and trying to figure how aggressive stimuli affect people’s r/K traits, vs sexual stimuli, vs pleasureable things like food, vs quick blips of K followed by long periods of r, vs long constant K, vs disease mortality that is totally random, and on and on.”
You have some strange dreams. It won’t happen. Individuals WITHIN A SPECIES are not R OR K. R AND K ARE NOT ADJECTIVES (Anderson, 1991: 57).
AC: “On Rushton, unless he ever mentioned politics (he didn’t),“
That’s meaningless though. You’re using the continuum he grabbed from Pianka (1970). THEREFORE, you’re wrong with your application since Pianka (1970) was rebutted decades ago (Graves, 2002)!
AC: “You have married black conservatives and married white conservatives and married Asian conservatives. They all have more in common psychologically than the leftists of their fellow races. Mixing them along racial lines only muddies the waters, and hides that all races have been exposed to harshness and ease, and have adapted the requisite psychologies to function and persist under either.“
No it doesn’t ‘muddy the waters’. I believe now you’ll point to black Trump supporters going against BLM or white Leftists going against their interests. SO WHAT. You can create any just-so story you’d like, you won’t be right.
Something AC doesn’t get is that using the discredited r/K continuum, conservatives would be r (lower IQ, more children; women who reported being religious stated that having children was more important to them; Hayford and Morgan, 2008) in comparison to liberals who would be K (fewer children, higher IQs). Of course, he just immediately states that cons are K and libs are r, since the verbal theory from Pianka (1970) had the ‘good traits’ on K and ‘bad traits’ on r. (Read r/K theory: Conservatives = r, liberals = K (reminder to the ignorant)). I’ve already covered that libs are more intelligent than cons (Kanazawa, 2010; Kanazawa, 2014), and that conservative countries have lower IQs (and are non-white and third world) in comparison to liberal countries (which are majority white…). Conservatives are more likely to be religious (Morrison, Duncan, and Parton, 2015; McAdams et al, 2015), and religious people have lower IQs (Zuckerman, Silberman, and Hall, 2013; Ritchie, Gow, and Deary, 2014; Pennycook et al, 2016; Dutton and Linden, 2017). Intelligence is also associated with social and economic liberal views (Carl, 2014). Lastly, research into the psychology of continents shows that liberal continents are more intelligent than conservative continents (African countries conservative, European countries liberal… what’s that tell you?) (Stankov and Lee, 2016). So, using Rushton’s/Pianka’s continuum, who looks r and K now?
This, as usual, is the perfect example of implicit bias. My team is best and has the good traits, the other team is worse and has the bad traits. It’s dumb, it doesn’t make sense. AC will try to get ‘the truth’ about this theory out to people, well he has a foil in myself. I enjoy talking about this and debating it, but it seems like most people don’t understand the ecology behind the theory. They have their biases and will search for anything to confirm them. That’s not science.
Stop pushing r/K theory. It’s long dead. Just because some non-specialist idealogue pushes something and warps studies to fit his views while ignoring contrary evidence, DOES NOT mean that the theory is ‘back’ in style or anything to that effect. One biased person picked up the dead body of the (discredited) r/K continuum and attempted to revive it. Well I’ve shot it back down. It’s dead. Let it rest in peace and stop attempting to revive it.

Pumpkinperson on the history of Black Africa
By Afrosapiens, 3650 words.
This article is a point by point refutation of Pumpkin Person’s extremely inaccurate and unscientific depiction of Black Africa’s history based on astrophysicist Michael Hart’s book Understanding Human History. While it might sound like a waste of time to give any attention to the writings of a clueless blogger, I found it was the perfect occasion to share the main specialist views on civilizational development and Sub-Saharan African history that many are still unaware of.
Although a couple of our commenters have been citing a lot of the accomplishments of black Africa, Dr. Michael H. Hart paints a very different picture in his book Understanding Human History.
To begin with, we have to question the value of Michael Hart’s account of human history when we know that this man is only an astrophysicist with no specialist background in history or archeology of any region of the world. Aside from Hart’s blatant incompetence in these areas of study, I can’t fail to mention his close links with the white nationalist movement and his well known association with American Renaissance. Knowing this, it is hard to believe that an incompetent writer with known ideological leanings would have produced an objective description of human history.
Hart’s book was published in 2007 so some of his claims may no longer be accepted as the archeological record has since become more complete and politically correct.
Pumpkin Person needs to elaborate on how the archaeological record could be “politically correct” or incorrect. Archeology is factual, not political. Either way, Michael Hart’s claims were wrong in 2007 and are just as wrong as of 2017 as his account of African history is in contradiction with the earliest reports by explorers of the continent.
For starters, Hart claims that farming was not practiced in Africa until it was brought to Egypt by Southwest Asians in 6000 BC and from there it spread to Ethiopia, Sudan and then West Africa by 3000 BC. Central and Southern Africa however, were still living in the paleolithic until 1000 BC, according to Hart.
This claim is obviously wrong and unsupported by genetic or botanical evidence. Pumpkin Person, doesn’t understand that societies do not invent “farming”, instead populations domesticate specific plants. The first plants were domesticated in West Africa around 5000BCE, these crops (sorghum, African rice, pearl millet, yam, fonio) are direct descendants of their local wild ancestors and were not grown in the Middle East and North Africa. This fact makes an introduction from those regions impossible, especially since transaharan communication was impossible before the domestication of the camel in the horn of Africa or southern Arabia around 3000 BCE. An other fact that Pumpkin Person seems to ignore is that populations do not transition from hunting and gathering to farming just from being exposed to agricultural populations, foreign crops are instead adopted by sedentary horticulturalist populations that have already domesticated non-grain plants. For this reason, the most common mode of diffusion of farming is not contact with another population but migration of the farmers themselves, which is why agriculture did not reach the southern half of Africa until the farming Bantu populations of West African origin gradually settled the region.
By 600 BC iron smelting occurred in Nigeria. Hart writes “It seems probable that knowledge of iron work had been introduced from the North or brought from the eastern Sudan.” Introduced or brought in by Caucasoids?
Once again, the external introduction hypothesis is unsupported by any sort of evidence, especially since West Africans started smelting copper in the Sahel by 2000 BCE, which was the first stage of metal working development before iron-metallurgy. Evidence from metal working and crop domestication confirm West Africa’s status as a place of independent transition from the paleolithic to the neolithic.
Hart notes that prior to 1500, sub-Saharan Africa could be divided into two wildly different sections. The exposed zone and the secluded zone. The exposed zone was all the parts that were in contact with Caucasoids, such as West Africa, Ethiopia, Somalia, small remote parts of the Indian Ocean colonized by Arab traders, and parts of the Atlantic coast where Portuguese traders had set up shop. The rest of sub-Saharan Africa was the secluded zone. A terrifying region roughly twice the size of Europe.
Being familiar with African historiography, I was very surprised to learn about this pretended division between a “secluded” and an “exposed” zone marking the history of the continent before 1500. Such a division never appears in the literature and searching for it on the Internet only led me to Pumpkin Person’s article, which implies that this distinction only exists in Pumpkin Person and Michael Hart’s heads. Also, it’d be interesting to find an actual map of the pretended “secluded zone” as well as a scientific translation of its “terrifying” character.
Nevertheless, it is true that African regions that were more exposed to the outside world benefited from the exchange of goods, knowledge and technology more than the more isolated parts of the continent, similarly to the rest of the world. However, places like the pre-islamic Sahel and savanna (Ghana Empire, Nok Civilization, Djenne-Djeno), the Gulf of Guinea (Benin, Yoruba states, Igbo states), the Great Lakes regions (Rwanda, Buganda), the Lower Congo (Kongo Kingdom, Kuba Kingdom) and Zimbabwe developed complex organized societies independently from Eurasian contact before 1500.
While the exposed zone was not poor, and benefitted from written languages brought by Muslim slave traders, Hart feels the indigenous peoples still failed to make a single contribution to World civilization.
Bold claims here. Firstly, it is well acknowledged that the University of Timbuktu founded under the rule of the Mali Empire was one of the Islamic world’s main learning centers staffed by local West African scholars with thousands of religion, science, poetry, history and novel manuscripts still remaining to this day. Secondly, “the Muslim slave traders” were not foreigners of North African or Middle Eastern ancestry as Pumpkin Person or Hart seem to imply, these Muslims were Black African Muslims (close to half Sub-Saharans are Muslim) and they were not “slave traders” per se. They indeed traded slaves, along with gold, ivory and gum and other African products.
But it is the vast secluded zone that bears the brunt of Hart’s poison pen. Described as a primitive and backward region until as recently as the 19th century, Hart notes that there were:
Interesting, but what is this “secluded zone” that he’s referring to? Can someone name some populations of this “secluded zone”?
-no wheeled vehicles, nor even the potter’s wheel
Which is common to every isolated region with low population density.
– no method of even joining together pieces of wood
It’s extremely hard to understand what he’s referring to. Given that most Africans all over the continent built wooden houses, or assembled different pieces of metal and wood to manufacture tools, weapons or musical instruments, this allegation doesn’t stand the test of reality.
-no beasts of burden or draft animals (though cattle was raised)
These characteristics are far from being exclusive to Africa even if we’re only mentioning the “secluded zone”, these animals were absent in the Americas too. Keeping large animals was made even more difficult in tropical Africa by the presence of tsetse flies killing animals and humans by transmitting African trypanosomiasis also known as sleeping sickness.
-not a single written language in the entire region, and thus no law codes, no philosophical works, no literature or even oral epic-poetry
Before expanding on the topic of writing, I must quickly react on this obviously wrong assertion that any place in Africa was devoid of oral literature. Besides the very rich record of such an oral literary tradition, African societies all over the continent are noticed by the existence of a social caste of storytellers best exemplified by the West African griots. As for writing, although it is true that most of Subsaharan Africa remained illiterate until colonization and the literate parts adapted or adopted foreign scripts (writing was only invented in Egypt, Sumer, China and Mesoamerica according to most specialists), evidence, mainly from the Cross River region of current day Nigeria, shows that Africans had developed proto-writing with the Nsibidi system used in courts and were thus only a few centuries away from developing a complete, fluid and ideographic writing system, tonal languages making alphabets hard to use.
-no coins or money
This remark makes no sense since all forms of exchange were barter or a slightly improved form of it before the introduction of real, modern fiat money. Anyway, differently shaped pieces of metal, shells and salt were common means of transaction all over Africa in precolonial times.
– no math beyond simple arithmetic,
Although the absence of written language greatly limits the development of mathematic science, it is obviously wrong to claim that Africans anywhere in the continent were unable of calculation above the level of simple arithmetic. Indeed, as this paper demonstrates in the case of central Africa, various memorization techniques were used to execute complex calculations prior to colonization.
-no cities beyond small towns
Anyone who knows that the difference between a city and a small town or a village is not the intelligence but the number of its inhabitants can only wonder what this is supposed to prove besides the fact that Africa’s population density was and is still very low, which is in line with the leading and unchallenged position among specialists that complex societies are the consequence of population density.
no temples, large monuments nor domes, arches, schools, hospitals, libraries nor paved roads.
Same thing as with cities, monumental architecture was not the product of superior intelligence, instead, it relied on huge pools of laborers to erect such structures whose construction commonly spanned over several decades or centuries.
Hart credits the ruins of Great Zimbabwe as the most notable construction in the secluded zone, but feels it was nothing compared to the Machu Picchu in South America, or Cambodia’s Angkor Wat complex, or Mesoamerica’s large cities and religious buildings. Hart notes that the giant statues on the tiny isolated Polynesian Easter Island were more impressive than anything found in the entire, secluded zone of black Africa.
This passage contains many inaccuracies. Firstly, Angkor Wat was by no means an isolated place. It was a Hindu, then Buddhist temple, and both religions went to Cambodia from India. As an assemblage of multiple stones to form a fortification system, Great Zimbabwe certainly necessitated more complex skills than carving statues in volcanic monoliths as seen in Easter Island. Machu Picchu, which is not a monument but an abandoned town is actually very similar to Great Zimbabwe, both are settlements built with locally available materials with a relatively simple architecture. Regarding Mesoamerican pyramids, they are absolutely not comparable to either Machu Picchu, Great Zimbabwe or Easter Island monoliths as they were built in a highly populated literate region with advanced mathematics and geometry which greatly facilitate architectural development.
-Almost no maritime skills. Hart notes the stunning fact that took Indonesians from the other side of the Indian Ocean, coming from 3000 miles away, to inhabit Madagascar in 500 AD, because Africans still had not reached it, even though it was only 250 miles off the East African coast. Nor did they reach the Cape Verde Islands, just a few hundred miles off the West African coast.
Africans are continental peoples, contrary to Indonesians who had spent millennia on archipelagos where seafaring across calm waters was the only means of communication between tiny islands. The African coast is straight and boarded by tumultuous oceanic waters, without peninsulas nor islands visible from the coast. For the same reason, Europeans never reached Madeira, the Azores or the Americas (apart from the Vikings, reaching Greenland and Newfoundland from Iceland at an unknown period) before the age of discoveries, Native Americans never reached Bermuda or the Galapagos and East Asians didn’t reach the Americas or any island in the Pacific. Continentality does not promote the development of seafaring skills whereas oceanic waters, with no island in sight from the coast give the impression of a boundary of the world. Nevertheless, Bantu peoples reached the Comoros in the sixth century soon after reaching the Eastern coast from their West African homeland, from there, they settled Madagascar at about the same time as Austronesians.
Hart also claims the secluded zone was primitive when it came to political and ethical matters, noting the lack of democracy and civil liberties and the common use of slavery and occasional cannibalism.
I wonder if this part has to be taken seriously. In fact, those things were common features in Africa, in and out of the “secluded” zone. But they were also common all over the world until someone invented and then enforced the idea of human rights. Duh!
Why was the secluded zone of black Africa so far behind virtually everyone else on Earth? In Guns, Germs and Steel, Jared Diamond argues that black Africa was simply cut off from the rest of the World, and thus didn’t have access to advances in knowledge, however Hart rejects this explanation because Native Americans were even more geographically isolated than black Africans, yet their societies were so much more advanced.
Wrong, Mesoamerica has impressive pyramids, the Andes have ancient ruined cities but those things definitely aren’t a common sight from Alaska to Patagonia. In fact, the area of the Americas where complex societies never existed is much larger than the whole Subsaharan part of Africa and is also much more “backward” since most populations did not acquire metallurgy and barely practiced agriculture, which makes them paleolithic societies.
Instead Hart favours the cold winters explanation. Races who left Africa tens of thousands of years ago, and got at least some exposure to the ice age, evolved higher intelligence to survive the cold, and once the ice age ended, this allowed them to create advanced culture and technologies.
This explanation is not supported by any genetic, archaeological, anthropological evidence. No Wurm-glaciation-related bottleneck has ever been reported by any geneticist, nor did any other related adaption on another trait. The only noticeable anthropometric change that came after the Wurm Glaciation is shrinking brain and body sizes. Also, the cradles of the neolithic revolution (all in low subtropical latitudes) were actually mildly affected by the last glacial maximum whereas such a scenario would have led one to expect agriculture or metallurgy to appear in more northerly regions.
Secondly, there is already a leading theory on the emergence and development of civilization that isn’t challenged and fits observable patterns. This theory does not focus on “qualitative” factors of human populations such as intelligence but simply on quantitative factors such as population density and exposure to long distance trade.
And it is no coincidence that complex societies emerged and developed in environments that were able to sustain high population densities thanks to their climate and vegetation, the quality of their soil, some characteristics of their terrain that prevented population dispersal and facilitated crowding, low disease burden and access to world trade. For these reasons, the different regions of the world experienced different trajectories of social development.
Australia and Oceania
Mostly lying in the tropical zone and greatly isolated from the Eurasian landmass, indigenous Australian and Oceanian societies developed in hostile environments and tiny islands preventing demographic expansion. Whereas Polynesia was settled by Austronesian populations that developed seafaring skills in the Indonesian Archipelago, Australia and Melanesia had no contact with the outer world until European exploration. No agriculture was ever developed in Australia, however Papua New Guinea is one place of independent domestication of crops, which along with continental Asian cultivates spread to Micronesia, Polynesia and Melanesia.
Central And Northern Asia
As a flat, arid and cold continental mass, Central and Northern Asia’s environments do not favor population density and complex social organization. Nomadism was traditionally a prevalent mode of subsistence in the region and and only a few complex permanent settlements emerged along the southern silk roads that were crucial to trans-Eurasian trade. Although the region has virtually no indigenous advancements, the Turkic and Mongolic warlike nomadic tribes have been able to take over the well established empires of Europe, East Asia, India, Persia and the Near-East.
Benefiting from some of the most fertile soils of the world, a temperate climate enabling long growing seasons and lowering the prevalence of disease, as well as a terrain made of enclosed plains and valleys in Northern China and narrow peninsulas and islands in Japan and Korea. East Asia’s environment has allowed the development of very complex societies that still boast some of the highest population densities in the world. Expanding southwards to the subtropical area, the Han Chinese found the ideal conditions for year long high yield riziculture allowed by abundant rainfall and fertile soils. East Asia is noticeable within the Eurasian landmass for the indigenous development of its agriculture and writing and its historical resistance to foreign influences, which likely resulted in a delayed social development relative to the potential conferred by its excellent environmental conditions.
Receiving neolithic technologies from the near east, complex societies first developed in the southern peninsulas of Greece and Italy where the terrain and the Mediterranean climate quickly allowed high population densities. By the end of the first millennium AD, Mediterranean technologies were established in the northern areas and the large scale movement of deforestation cleared vast agricultural areas with fertile soils under an excellent temperate low-disease climate that led to a population boom that quickly allowed Europe to rise to global prominence.
Middle East and North Africa
Often called the cradle of civilization, the Middle East and North Africa reunite the optimal conditions for the emergence of complex societies. A warm, temperate climate with balanced rainfall combined with fertile valleys (Nile and Mesopotamia) allowing year-long irrigation, all enclosed by inhospitable deserts preventing population dispersal. Moreover, the region finds itself at the crossroads of the Old World and has dispersed then received technologies and commodities from neighboring eras.
North America and the Arctic
Similarly to South America and contrary to Subsaharan Africa as depicted by Pumpkin Person and Michael Hart, North America shows a stark contrast between highly developed Mesoamerica and the mostly paleolithic other regions and is a perfect illustration of the fundamental role of population density in the emergence of civilization. Whereas the narrow temperate highlands and warm lowlands of the Mesoamerican isthmus enabled highly productive yearlong agriculture and prevented population dispersal thus leading to very high population density and civilization in isolation from the Old World, the northern areas remained underpopulated due to a vast, flat continental landmass.
Nevertheless, the eastern temperate areas of Canada and the United States, benefiting from a balanced climate and fertile soils sustained some small scale agriculture but it is only after European settlement that these ideal conditions were fully exploited. Another specificity of the Americas compared to the Old World is the absence of disease due to lack of domestication of large animals. Whereas this could have been beneficial for demographic growth in precolumbian times, it proved to be fatal quickly after contact with the old-world as the indigenous populations had evolved no genetic immunity to resist Old World disease or to spread New World disease to the invaders.
Comparably to North America, the development of complex societies is restricted to the very narrow Andine Altiplano, a temperate highland plateau where indigenous populations subsisted on the cultivation of potatoes. A colder climate and a shorter growing season prevented Andine societies to achieve population densities that equaled that of Mesoamerica and for this reason, they couldn’t develop complex technologies to the same level. The rest of the South American landmass has similar environmental characteristics to Subsaharan Africa which is a very warm area of flat arid grasslands and equatorial rainforests. The soils are poor for grain crops and the population densities are accordingly low.
Entirely lying in the tropical zone, South-East Asia includes the Indochinese peninsula and the Indonesian Archipelago. Whereas some volcanic islands like Java as well as more temperate regions in Cambodia, Thailand and Vietnam were able to sustain high population densities, most of the local technology and cultural elements were acquired from the Indian Subcontinent and, to a lesser extant, East Asia. The constellation of islands in Indonesia led to the formation of thalassocracies whose maritime tradition allowed the settlement of Austronesian peoples in remote islands like Hawaii, Madagascar and Easter, but curiously not Australia.
Southern Asia was for a long time the second most advanced region in the world after the Middle East and North Africa and similarly adopted and spread technologies and cultural practices from and to the neighboring regions. Centered around the Indus and the Ganges valleys as well as the Deccan plateau, Southern Asia has fertile soils, warm and moderately humid climates in that alternate with more arid climates where a large variety of crops can be grown all year thanks to powerful rivers that allow irrigation. Seasonal monsoon provide ideal rainfall for rice cultivation. Along with Eastern China, Northern India currently has some of the most densely populated areas of the world.
Subsaharan Africa is a vast, flat landmass under very warm climates which result in environments made of deserts, arid grasslands and equatorial rainforests. Short growing seasons, high disease burden and population dispersal (slave trade included) have made it particularly difficult to achieve sufficient population densities that lead to more complex societies compared to the rest of the world from which the region remained partially isolated. Nevertheless, centralized states were established in the Sahel and the northern Savannas of West Africa, in the Gulf of Guinea, the Lower Congo, the Ethiopian Highlands, the Great Lakes region, the Swahili Coast and Southern Africa. Contrary to the imaginary “secluded zone” theory proposed by Pumpkin Person and Michael Hart, social complexity is in Africa as elsewhere in the world more a function of population density than a function of exposure to “more evolved races”.

Why Do Jamaicans, Kenyans, and Ethiopians Dominate Running Competitions?
Much has been written about the genotypic and phenotypic differences in Jamaicans, Kenyans, and Ethiopians. Why do they dominate these competitions? Is it cultural? Genetic? Does training matter more? Grit? Expertise? There are multiple reasons that they have such an advantage, the most important one being their morphology/somatype. Of course other physiologic and morphologic factors come into play for these three populations, but the greatest physical advantage they have is their somatype which lends itself to running—whether short, medium or long distance.
Back in July, I argued that the wide-hipped Neanderthals were stronger than the recently migrated Homo sapiens, due mostly to pelvic anatomy (along with Neanderthal protein intake). That’s one of the keys to explaining African dominance in running: their long slender bodies with high limb ratios.
Kenyans and Ethiopians
Kenyan distance running is driven by an ethny named the Kalenjin, particularly of the Nandi tribe. Much research has been undertaken on the physiology and morphology of certain subpopulations of Kenyans, with a complex genotype, phenotype, and even SES interaction driving the dominance of this subpopulation (Tucker, Onywera, and Santos-Concejero, 2015). Another important factor is their low BMI. Kenyans have the lowest BMIs in the world at 21.5, which considerably helps in regards to distance running (Radovanovic et al, 2014; Shete, Bute, and Deshmukh, 2014; Sedeaud et al, 2015).
Kenyans—like Jamaicans and Ethiopians—dominate these competitions due to a complex interaction between genes, environment and SES (Tucker, Onywera, and Santos-Concejero, 2015). Though, of course, a lot of what makes certain Kenyan populations dominate is trainable in other populations. Caucasians can have similar trainability in regards to Vo2 max, oxidative enzymes, and running economy. However, Kenyans are more likely to be slender with longer limbs which is a huge advantage in these competitions. So having a good running economy and a high Vo2 max may be the primary causal factors that cause them to be so good at distance running, with, as I’ve noted in the past, a higher genetic ceiling for high Vo2 max, along with high-altitude training (Larsen, 2003). Though Saltin et al (1995) conclude that physical activity during childhood combined with intense training as a teenager explains the higher Vo2 max in Kenyan boys. Other factors such as low blood lactate and ammonia accumulation are also important.
Genetics, though, is the most likely explanation for African distance-running dominance (Vancini et al, 2014; see Scott and Pitsiladis, 2007 for alternative view that as of yet there are no genetic evidence for African running superiority).
Not all studies show that Kenyans have more slow-twitch (type I) fibers than Caucasians, though the oxygen cost of running at a given velocity was found to be lower in elite Kenyan runners compared to non-Kenyans, which may be due to body dimensions. Apparently, there is no indication that Kenyans possess a pulmonary system that confers a physiologic advantage over non-Kenyans (Larsen and Sheel, 2015). Ethiopian diets, however, met the most recommendations for macronutrients, but fluids were lacking (Beis et al, 2011), similar to what is found on similar studies in Kenyans (Onywera et al, 2003).
It is important to note that not all of the literature out there says that there are mainly physiologic/genetic reasons for their success in distance running; other factors that may be at play are somatype which leads to exceptional biomechanical and metabolic efficiency, high-altitude training, and the want to succeed for economic and social advancement (Wilbur and Pitsiladis, 2012). Oxygen transport of the blood doesn’t explain Kenyan dominance either, they have similar oxygen transport as elite German runners (Prommer et al, 2010). Though, women and men from Ethiopia and Kenya, although they only account for <0.1% of the marathons and half-marathons, achieved the fastest times and were the youngest in the half-marathons and full-marathons (Knechtle et al, 2016). Similar results were seen in Switzerland, with male Africans being faster and younger than non-Africans (Aschmann et al, 2013).
From the years 2000-2014, Knechtle et al (2017) analyzed the Boston, Berlin, New York, and Chicago marathon along with the Stockholm marathon. Over this time period, Ethiopian men improved their times, but Ethiopian women didn’t. Age increased in Ethiopian men, but not women. Female and male marathon runners from Ethiopia were the fastest (Knechtle et al 2017). More studies, though, are needed to unravel the complex relationship between environmental and genetic factors that cause East Africans to dominate distance running (Onywera, 2009). However, elite endurance athletes consistently test higher than non-elite athletes on running economy, Vo2 max, and anaerobic threshold (Lorenz et al, 2013), and mechanical work may be able to predict recreational long distance performance (Tartaruga et al, 2013).
Jamaican sprinting dominance has been chalked up to numerous factors, most recently, symmetry of the knees and ankles (Trivers, Palestis, and Manning, 2013; Trivers et al, 2014). Trivers et al (2014) write in the Discussion:
Jamaicans are the elite sprinters of the world. Why? If symmetry of knees and ankles is a factor, why should Jamaicans be especially symmetrical (there is no knowledge of whether they actually are)? One possibility is heterozygosity for genes important to sprinting. The slave trade greatly increased heterozygosity on the West African side by mixing genes up and down the West coast of Africa from Senegal to Nigeria , . Recently a mtDNA haplotype has been isolated that correlates with success in African American–but not Jamaican–sprinters . Since there is a general (if often weak) positive relationship between heterozygosity and body symmetry  we are eager to do targeted studies of genomics on areas associated with sprinting, including energy substrate utilization, muscle fibre-type distribution and body composition analyses (with specific reference to the shape and size of the glutei maximi). Fast twitch (anaerobic) muscle fibres are characterized by specific adaptations which benefit the performances of explosive high-intensity actions such as those involved in sprinting. Notably, West Africans appear to have a higher fast twitch muscle fibre content than do comparable Europeans (67.5% vs 59% in one sample , as cited in ).
It’s interesting to note that the mtDNA haplotype predicts success in African American sprinters, but not Jamaicans. In regards to mtDNA haplotypes, Jamaican sprinters had statistically similar mtDNA haplotypes, which suggests that the elite sprinters arose from the same source population which indicates that there is no population stratification or isolation on sprint performance. African American sprinters and non-sprinters, on the other hand, had statistically significant differences in mtDNA, which implies that maternal ancestry plays a part in sprinting performance (Deason et al, 2011). Studying both maternal and paternal haplotypes to see where source populations originate is important in these fields, since if we know where their population came from, then we can better understand the hows and whys of elite running performance—especially between race. Though demographic studies on Jamaicans show that elite sprinters come from the same demographic population, so genetics cannot possibly account for Jamaican sprinting success, so their sprinting success may be related to environmental and social factors (Irving et al, 2013). We know little about the genomics of elite sporting performance (Pitsiladis et al, 2013), so the physical correlates (somatype) and physiologic correlates will do for now.
Usain Bolt is the current fastest man in the world, due in part to his anthropometric advantage (Krzystof and Mero, 2013). As everyone knows, you cannot teach speed (Lombardo and Deaner, 2014). Bolt himself has a large advantage, in part, to his power development and biomechanical efficiency compared to the people he competes with (Beneke and Taylor, 2010). Though one study has noted that a human may be able to run faster quadrupedally than bipedally–stating that at the 2048 Olympic Games, that the fastest human on the planet may well be a quadrupedal runner (Kinugasa and Usami, 2016). One of the most important factors of acceleration in the 100m sprint is stride frequency (Mackala, Fostiak, and Kowalski, 2015).
In Afro-Caribbean adolescents, body height and stride number to body height ratio were the main determinants of sprint performance (Copaver, Hertogh, and Hue, 2012). Body height being a predictor of sprint performance is nothing new; taller people have longer limbs; longer limbs cover more distance per step. Indeed, sprinters are taller than the American population, there is more variability in men than in women, sprinters have lower body mass and the height range excludes people who are really tall or really short (Uth, 2005).
I will touch on fiber typing again since I’ve come across new information on it.
East Asians are less likely to have the RR allele of the ‘sprint gene’ (MacArthur and North, 2004) (ACTN3) while Bantus are more likely to have it. Alpha-actinen-3 is a skeletal muscle isoform which is encoded by the ACTN3 gene. Alpha-actinen-3 deficiency is common in the general population (North, 2008; Berman and North, 2010), which means that most people in the general population are XX. Eighteen percent of the population on earth is homozygous for this mutation (Ivarsson and Westerblad, 2015). This allele is the 577X allele, and Bantus are less likely to have it while Eurasians are more likely to have it. The frequency of the RR genotype is also highest in Bantus than in Asians (Mills et al, 2001). This is one very important reason why Eurasians are not faster than Africans (somatype matters too, of course).
Elite sprinters are more likely to be RR and less likely to be XX. Why does this matter? It matters because the RR genotype with the right morphology, fiber type (fast twitch) and contractile properties of the individual fast twitch fibers contribute to heightened performance with an RR genotype (Broos et al, 2016). Jamaicans are also less likely to have the XX genotype (~2 percent) along with Kenyans (Scott et al, 2010). So this shows that since Jamaicans are less likely to be XX, they’re more likely to be RR. So since XX i negatively associated with sprint status, then populations that have a lower frequency will be more likely to have more sprinters, whereas a population that has the genotype will have fewer sprinters.
This is one of many genetic factors that account for elite sprinting performance between populations. So, clearly, the right muscle fiber type combined with the right genotype from the ACTN3 gene infers an advantage, contrary to Daniel MacArthur’s claims that it does not (one of the authors of numerous studies on the ACTN3 gene).
The genetics of sprinting/distance running is currently poorly understood. Though we have a few candidates (and they’re really good, showing variation where they should) like the RR ACTN3 genotype combined with fast twitch fibers. This is very important to note. If you’re missing this, and you’re short with a low Vo2 max and low limb length, there’s an extremely high chance you will not be an elite sprinter/distance runner. I cannot emphasize enough how much the physical factors mean when it comes to this.
It is possible that SES variables combined with other psycho-social factors could explain why these three populations excel so well in these sports. Though, on the other hand, you cannot discount that the individual has to have the right somatype and physical capabilities first. Contrary to popular belief, fiber typing DOES give an advantage, especially if combined with other variables. Low BMI is very important, as are long limbs and a taller than average height.
When it comes to Jamaicans, symmetry of the knees and ankles help considerably, along with a low body mass and taller body. SES factors could be driving the will to compete in these three populations, however, the physical ability needs to be there first, then it needs to be nurtured. Over the next 5 to 10 years, we will have a better understanding of why some populations excel over others and that will largely be due to somatype, physiology, and genetic factors, with SES and other psycho-social factors driving the want to excel in the sport.
The physical differences that underlie the success of these three populations needs more study. Elite athletes of Jamaican, Kenyan, and Ethiopian descent need to be studied more to untangle the physiologic, psychological, physical and social factors that have them excel so well. We know that certain combinations of traits infer a great advantage in certain populations, we now just need enough elite athletes of these populations to study to see how and why they excel so much. The current body of research reviewed here is a good start, though it does leave some questions unanswered.
Weight Loss and the Microbiome
Last month I argued that there was more to weight loss than CI/CO. One of the culprits is a virus called Ad-36. Obese people are more likely to have Ad-36 antibodies in comparison to lean people, which implies that they have/had the virus and could be a part of the underlying cause of obesity. However, a paper was recently published that your stool can predict whether or not you can lose weight. This is due to how certain bacteria in the gut respond to different macronutrients ingested into the body.
ScienceDaily published an article a few days ago titled Your stools reveal whether you can lose weight. In the article, they describe the diets of the cohort, which followed 31 people, some followed the New Nordic Diet (NND), while others followed the Average Danish Diet (ADD) (Hjorth et al, 2017; I can’t find this study!! I’ll definitely edit this article after I read the full paper when it is available). So 31 people ate the NDD for 26 weeks, and lost 3.5 kg (7.72 pounds for those of us who use freedom numbers) while those who ate the ADD lost an average of 1.7 kg (3.75 pounds for those of us who use freedom numbers). So there was a 1.8 kg difference in pounds lost between the two diets. Why?
Here’s the thing: when people were divided by their microbiota, those who had a higher proportion of Prevotella to Bacteriodoites lost 3.5 more kg (7.72 pounds) in 26 weeks when they ate the NND in comparison to the ADD. Those who had a lower proportion of Prevotella to Bacteriodoites lost no additional weight on the NND. Overall, they say, about 50 percent of the population would benefit from the NND, while the rest of the population should diet and exercise until new measures are found.
The New Danish Diet is composed of grains, fruits, and vegetables. The diet worked for one-half of the population, but not for the other. The researchers state that people should try other diets and to exercise for weight loss while they study other measures. This is important to note: the same diet did not induce weight loss in a population; the culprit here is the individual microbiome.
Now that those Bacteroidotes have come up again, this quote from Allana Collen’s 2014 book 10% Human: How Your Body’s Microbes Hold the Key to Health and Happiness:
But before we get too excited about the potential for a cure for obesity, we need to know how it all works. What are these microbes doing that make us fat? Just as before, the microbiotas in Turnbaugh’s obese mice contained more Firmicutes and fewer Bacteroidetes, and they somehow seemed to enable the mice to extract more energy from their food. This detail undermines one of the core tenets of the obesity equation. Counting ‘calories-in’ is not as simple as keeping track of what a person eats. More accurately, it is the energy content of what a person absorbs. Turnbaugh calculated that the mice with the obese microbiota were collecting 2 per cent more calories from their food. For every 100 calories the lean mice extracted, the obese mice squeezed out 102.
Not much, perhaps, but over the course of a year or more, it adds up. Let’s take a woman of average height. 5 foot 4 inches, who weights 62 kg (9st 11 lb) and a healthy Body Mass Index (BMI: weight (kg) /(height (m)^2) of 23.5. She consumes 2000 calories per day, but with an ‘obese’ microbiota, her extra 2 per cent calorie extraction adds 40 more calories each day. Without expending extra energy, those further 40 calories per day should translate, in theory at least, to a 1.9 kg weight gain over a year. In ten years, that’s 19 kg, taking her weight to 81 kg (12 st 11 lb) and her BMI to an obese 30.7. All because of just 2 percent extra calories extracted from her food by her gut bacteria.
This corresponds with the NND/ADD study on weight loss… This proves that there is more than the simplistic CI/CO to weight loss, and that an individual’s microbiome/physiology definitely does matter in regards to weight loss. Clearly, to understand the population-wide problem of obesity we must understand the intricate relationship between the microbiome/brain/gut/body relationship and how it interacts with what we eat. Because evidence is mounting that the individual’s microbiome houses the key to weight loss/gain.
Exercise does not induce weight loss. A brand new RCT (randomized controlled trial) showed that in a cohort of children who were made to do HIIT (high-intensity interval training) did show better cardiorespiratory fitness, but there were no concomitant reductions in adiposity and bio blood markers (Dias et al, 2017). What this tells me is that people should exercise for health and that ‘high’ that comes along with it; if people exercise for weight loss they will be highly disappointed. Note, I am NOT saying to not exericse, I’m only saying to not have any unrealistic expectations that cardio will induce it, it won’t!
Bjornara et al (2016) showed that, when the NND was compared to the ADD, there was better adherence to the NND when compared to the ADD. Poulskin et al (2015) showed that the NND provided higher satisfaction, and body weight reduction with higher compliance with the NND and with physical activity (I disagree there, see above).
This study is important for our understanding of weight loss for the population as a whole. More recent evidence has shown that our microbiome and body clock work together to ‘pack on the pounds‘. This recent study found that the microbiome “regulate[s] lipid (fat) uptake and storage by hacking into and changing the function of the circadian clocks in the cells that line the gut.” The individual microbiome could induce weight gain, especially when they consume a Western diet, which of course is full of fat and sugar. One of the most important things they noticed is that mice without a microbiome fared much better on a high-fat diet.
The microbiome ‘talks’ to the gut lining. Germ-free mice were genetically unable to make NFIL3 in the cell lining of the gut. So germ-free mice lack a microbiome and lower than average production of NFIL3, meaning they take up and store fewer lipids than those with a microbiome.
So the main point about this study is the circadian rhythm. The body’s circadian clock recognizes the day/night system, which of course are linked to feeding times, which turn the body’s metabolism on and off. Cells are not directly exposed to light, but they capture light cues from visual and nervous systems, which then regulates gene expression. The gut’s circadian clock then regulates the expression of NFIL3 and the lipid metabolic machinery which is controlled NFIL3. So this study shows how the microbiome interacts with and impacts metabolism. This could also, as the authors state, explain how and why people who work nights and have shift-work disorder and the concurrent metabolic syndromes that come along with it.
In regards to the microbiome and weight loss, it is poorly understood at the moment (Conlon and Bird, 2015), though a recent systematic review showed that restrictive diets and bariatric surgery “reduce microbial abundance and promote changes in microbial composition that could have long-term detrimental effects on the colon.” They further state that “prebiotics might restore a healthy microbiome and reduce body fat“(Segenfrado et al, 2017). Wolf and Lorenz (2012) show that using “good” probiotic bacteria may induce changes in the obese phenotype. Bik (2015) states that learning more about the microbiome, dysbiosis (Carding et al, 2015), and how the microbiome interacts with our metabolism, brain, and physiology, then we can better treat those with obesity due to the dysbiosis of the microbiome. Clark et al (2012) show how the mechanisms behind the microbiota and obesity.
Weight loss is, clearly, more than CI/CO, and once we understand other mechanisms of weight loss/gain/regulation then we can better treat people with these metabolic syndromes that weirdly are all linked to each other. Diets affect the diversity of the microbiome, the diversity of the microbiome already there though, may need other macro/micro splits in order to show differing weight loss, in the case of the NND and ADD study reviewed above. Changes in weight do change the diversity of the microbiome of an individual, however, the heritable component of the microbiome may mean that some people need to eat different foods compared to others who have a different microbiome. Over time, new studies will show how and why the macro/micronutrient content matters for weight loss/gain.
Clearly, reducing the complex physiological process of weight gain/loss to numbers and ignoring the physiological process and how the microbiome induces weight gain/loss and works together with our other body’s cells. As the science grows here we will have a much greater understanding of our body’s weight loss mechanisms. Once we do that, then we can better help people with this disease.
Does Human Potential Lie in the Embryo?
The debate on human potential—and whether or not it is innate and ‘in the genes’—is steeped in bias and ideology from both sides (despite the claims that HBD ‘has no ideological bias’). Hereditarians assume that human potential is ‘in the genes’, and some even believe that human potential is testable during embryonic development (like psychologist Stuart Ritchie). However, this assumes two things: 1) that genes are the masters of development, and not the slaves, and 2) that differences in potential are already encoded in the genes of the homunculus. I will show that these two assumptions are wrong.
Embryonic development is a part of a larger whole of a complex process. Cells, in the beginning of embryonic development, are totipotent—meaning they have the ability to become any type of cell (Condic, 2014) depending on what the intelligent system calls for. This is important to note: at the beginning, all cells are the same and, despite having the same genes, “they have the same potential to become any kind of differentiated cell for a particular organism” (Richardson, 2017: 156). It is also possible to grow stem cells in a lab that are pluripotent—which have the ability to become any cell in the body—called iPS cells.
Even embryos that are of low quality do end up developing into healthy babes (emphasis in second para mine):
Embryo quality as we see it under the microscope in the IVF lab gives us some reasonable ability to predict the chances for pregnancy after the embryo transfer procedure. However, because there are many other contributing factors involved that we can not see or measure, the generalizations about “quality” made from grading embryos are often inaccurate.
We see some cycles fail after transferring 3 perfect looking embryos, and we also see beautiful babies born after transferring only one “low grade” embryo. The true genetic potential of the embryo to continue normal development is very difficult to measure accurately unless we utilize preimplantation genetic screening (PGS) to select chromosomally normal embryos for transfer.
So it seems that not even just looking at the quality of the embryo will show you if it will grow into a healthy baby with no birth complications. Potential must come after the embryonic stage of development. Another thing about testing the ‘quality’ of the embryo: it tells nothing about “what is going on inside the embryo genetically“.
The thing is, most chromosomal and other defects in any embryos can be noted under a microscope within 3 days of the embryo forming. And if you paid attention to totipotent cells earlier, you’d know that those cells have the potential to become any cell in the body—which is driven by the body’s intelligent systems/cells.
So embryonic quality really has no bearing on whether or not the embryo will eventually reach birth. As I’ve argued before in Human Mating and Aggression—An Evolutionary Perspective, the age of the mother is one of the strongest predictors of whether or not there will be deleterious effects on the child—mostly after 35 years of age (O’Reilly-Green and Cohen, 1993; van Katwijk and Peeters, 1998; Stein and Susser, 2010; Lampinen, Vehviläinen-Julkunen, and Kankkunen, 2009, Jolly, 2010; Yaniv et al, 2010; Liu et al, 2011). However, there is evidence that a woman can be too young to become a mother (Geronimus, Korenman, and Hillemeier, 1994; Fall et al, 2015) and that children born to young mothers “might be better off if the parents waited a few years” (Myrskyla and Fenelon, 2012). The same holds true for fathers, with it recently being observed that older fathers and their offspring have lower evolutionary fitness even over across four centuries (Arslan et al, 2017). So it seems that the best predictor of embryonic quality is parental age (Scheffer et al, 2017)—not what an embryo really looks like or the totipotent cells already in the embryo.
So there is no test for the genetic potential of embryos and sperm—with the best tell being parental age. Embryonic development is a part of the intelligent developmental system and each stage of embryonic development is brand new, rather than being the cause of an already laid out blueprint. So even though the embryo has all of the same genes (in totipotent cells), they have the potential to become any cell in the body which is directed by the intelligent system (as noted above).
So if you understand embryonic development and how it’s a part of the intelligent system itself and not a part of an already laid out blueprint, then you’ll understand how potential—as we know it— is not in the embryo. They all have the same kinds of totipotent cells which have the chance to become any cell in the body which are then activated and used by the intelligent physiology. The age of both parents are the best predictors of embryonic quality—just by looking at the embryos after they’ve developed from blastocytes, you cannot infer that embryo’s potential.
Ken Richardson also responded to Stuart Ritchie’s article It’s now possible, in theory, to predict life success from a genetic test at birth to which Ken Richardson responded to. Potential is not in the embryo due to the number of totipotent cells in the embryo. Even ‘low-quality’ embryos can become healthy babes, so ’embryonic quality’ is not a good measure of whether or not it will be born with a defect, etc.
Worldwide IQ estimates based on education data
By Afrosapiens, 2851 words
One of the leading theories to explain differences in cognitive test performance between time and place is that intelligence as measured by such tests is affected by exposure to formal schooling and the cognitive demands of a high-technology society (D. Marks, JR. Flynn). One of the strongest evidence for such an effect of schooling on IQ comes from a reform in the Norwegian school system in which an expansion of compulsory schooling was associated with a 3.7 points increase in IQ per additional year of education between pre-reform and post-reform cohorts. In order to test this relationship between years of schooling and commonly reported national IQ averages, I used data from the United Nation’s Development Program to estimate the average IQ of each country’s adult and school-age population. Adult IQs were estimated from mean years of schooling completed by adults aged 25 and older whereas School-population IQs were estimated based on the expected years of schooling that a student is supposed to complete if the enrollment ratios from primary through tertiary education remain constant. All variables were reported in year 2015. Great Britain was chosen as the reference country and assigned a default value of 100 on both variables. For each country, a difference of one year in completed or expected schooling added or removed 3.7 IQ points. Adult IQ and School-age population IQ were averaged to estimate the most probable mean IQ that would be found by randomly reviewing literature without controlling for the age or the health and socio-economic profile of the sampled individuals.

In comparison to the mean national IQs mainly reported by Richard Lynn, 65 countries differed by less than 5 IQ points using the present methodology. It can be said that such small differences validate Lynn’s estimates since it is unlikely that years of education have the same cognitive value in every country and likewise, averaging adult IQ and school-age population IQ without controlling for a country’s age structure somewhat weaken the representativeness of my findings. Differences larger than 5 points were found for 30 countries, and in these cases, I suspect it is due to Lynn manipulating the data to fit racial patterns, Sub-Saharan African countries have been systematically under-estimated and East-Asian ones have been systematically over-estimated by Lynn, also, Some nations in Europe, the Middle-East, South-Asia and Latin America seem to have their scores manipulated in order to appear closer to what they would be based on their racial composition.
Such inconsistencies result in incoherences between the reported IQs and the educational and socio-economic outcomes (regardless of which variable influences the other) of the affected countries and support the accusations of racially-motivated fraud in Richard Lynn’s data collection. In the same way, estimating the mean IQs of countries for which direct data is missing by averaging the figures of neighboring countries of similar ethno-racial composition is unwarranted as race does not seem to play a role in a country’s cognitive performance.
In spite of all the deserved criticism that Lynn’s data met, it can be said that most of the commonly cited mean IQs out of Africa and East-Asia are reliable and that a strong relationship between human capital and human development exists whether we measure it by IQ or years of education. The causes of international variation in school quality and enrollment are well-known and come down to school and student characteristics. Schools in developing countries face numerous challenges: lack of basic amenities such as electricity, potable water, air-conditioning and heating, like of educational supplies (school rarely have enough textbooks and rely on chalk and blackboards), high student to teacher ratios (primary school classes with more than 50 students are common low-income countries), chronic teacher absenteeism (teachers usually have a business on the side), obsolete pedagogy, outdated or irrelevant curricula, multilingualism, exam-corruption, low public funding, misguided policies, gender and ethnic discrimination. Pupils are held back by poor health and nutrition resulting in developmental delays, tuition fees and supplies that poor families can’t afford, war, population displacement, absent educational resources at home, low parental education, lack of transportation, child labor, excessive use of grade repetition, mismatch between school curricula and daily life demands and many other factors. Differences in human capital have large implication in terms of workforce qualification and social behavior, which contribute for a large part to a country’s socio-economic development. The present findings provide evidence for large international inequalities in inter-generational change in educational outcomes which are probably the driving cause of the Flynn effect.
Intergenerational change in cognitive performance.
Estimating IQs from the current school enrollment rates and the mean educational attainment of adults provide insights regarding intergenerational differences in cognitive performance. We can see from these figures that the countries that developed the fastest show large intergenerational differences in education/IQ favoring the younger cohorts, these countries are concentrated in South America, Southern Europe, West Africa, the Middle-East and Oceania, Ethiopia and China also show trends that are in line with their recent economic success. On the other hand, many ex-USSR countries, as well as Japan, Cuba, South Africa, Zimbabwe and the Philippines have been stagnant or even declining relative to the United Kingdom and this is also reflect in their poor socio-economic performance in the last decades. War-torn South Sudan and the Central African Republic experience alarming declines in their educational performance that expose them to grave humanitarian crises in the future. Although there is a clear relationship between socio-economic progress and gains in cognitive performance, a country’s ability to capitalize on its intellectual potential remains highly dependent on its leadership and the odds of the world-market, that’s why theories claiming that IQ is the main driver of global inequalities are not tenable in the light of the current evidence.
Update 09/07/2017 – Detailed comparison with Lynn’s Data
To test the predictive power of my estimates in comparison to Lynn’s, I decided to focus only on the world’s 20 most populous countries. The reason for that is that these countries are home to 70% of the world’s population and the law of large numbers says that they are likely more representative of whatever they could represent. On the other hand, the 100+ other countries are home to only 30% of humanity. They are a source of statistical noise due to extreme outlying values and differences in regional political fragmentation that would hide or weaken general trends better evidenced by considering large countries.
Correlations and averages:
Noticing an abnormal 22 points gap between Sub-Saharan African IQs and the world average on Lynn data, Suspecting that extremely low values would flaw the correlations, I tested if my estimates and Lynn’s would retain the same predictive power with the African IQs excluded. My assumption was that a strong causal relationship would leave the correlations unchanged no matter which countries were included whereas any change in predictive power resulting from excluding some countries would cast doubt on the accuracy of the reported data.
Similarly to my previous calculation including all the countries for which data were available, I found a 0.96 correlation between my estimates and HDI, Lynn’s estimates correlation with HDI was higher (+0.06) than with the worldwide data, but still largely inferior to mine. Removing African countries, the predictive power of my estimates remained the same (+02) whereas Lynn’s significantly decreased (-0.13) and left a predictive gap of 0.24 favoring my estimates. However, given the fact that my estimates are based on variables that are included in the calculation of HDI, such a high predictive power as to be met with caution.
IQ-GDP per capita correlation:
My previous calculation from the worldwide data yielded a correlation coefficient of 0.65 between my IQ estimates and GDP/capita and 0.60 for Lynn’s. Among the 20 most populated countries, the correlation rose by 0.24 points to 0.89 with my estimates and by 0.12 points to 0.72 with Lynn’s. Excluding Sub-Saharan African countries did not affect the predictive power of my estimates (+0.01) and further weakened Lynn’s by 0.04 points, resulting in a 0.22 gap in predictive power favoring my estimates again. This correlation of 0.89 between my IQ estimates and GDP per capita within the world’s population top 20 countries likely is the highest correlate of IQ ever reported in the psychological science and gives strong support to the relationship between schooling, economic development and cognitive ability.
IQ-Life expectancy correlation:
Compared with the worldwide database, the correlation between my IQ estimates and life expectancy was down 0.04 points within the world’s top 20 to 0.76, Lynn’s went up by o.o5 points to 0.84. However, removing Sub-Saharan Africa left the predictive power of my estimates unchanged whereas Lynn’s fell by 0.13 points to 0.71. My estimates again predicted life expectancy better by a small 0.4 points this time.
Not estimated previously, my data finds an non-existent relationship between IQ and homicide rate (-0.01) and excluding Sub-Saharan Africa confirmed a null relationship between homicide rates and IQ in the rest of the world. Lynn’s estimates showed a low negative correlation between IQ and homicide (-0.35) and the exclusion of African countries further lowered the correlation (-0.25). Lynn’s estimates had a better predictive power which still remained in the range of low statistical significance.
Adding a new variable, I found a negative correlation of -0.69 between my IQ estimates and Fertility, the correlation remained the same (-0.68) with the African countries excluded. The correlation between Lynn’s IQs and fertility was stronger (-0.84), but removing African data decreased it by 0.18 points to 0.66. My estimates ended up with a slightly stronger predictive power (+0.02).
In addition to having a stronger and globally consistent predictive power, my estimates reveal how Richard Lynn manipulates the data to fit desired racial patterns.
As expected from the 0.96 correlation between my IQ data and HDI, the ranking of countries by cognitive ability shows a perfect gradient from high to low development status. Moreover, the highest gap between two following countries is the 6 points separating Russia and Iran, showing a marked difference between the developed and the developing world.
Ranking countries by Lynn-estimated IQs results in a whole other pattern in which a country’s dominant ancestry seems to be the only variable that matters. East-Asians are on top, followed by Western Europeans, then Eastern-Europeans, South-East Asians, fair skinned Middle-Easterners (Turkey and Iran) and Latin Americans, Austronesians (Indonesia and the Philippines), South Asians and Arabs, and finally Sub-Saharan Africans far below, with a huge 10 points gap (the largest between two following countries in his dataset) separating Bangladesh from Nigeria.
The manipulation is quite apparent, Lynn largely over-estimated China (+22), Japan (+7) to make East-Asians cluster on top, thus protecting himself from accusations of nordicism and giving support to the inter-cultural validity of the IQs that he cherry-picked. The western European and Russian data remained mostly unchanged. Vietnam (+11) and Thailand (+5) were given a bonus for their genetic proximity to North-East Asia that is supposed to make them score in the low 90s despite their lack of development. Little changes were brought to the scores of the Latin American, Middle-Eastern and Austronesian countries usually scoring in the mid-80s. Major fraud (+14 in Pakistan, +7 in Bangladesh) was done to lift up South-Asian countries out of the 70s range and excluding Sub-Saharan Africa as the only region scoring 70 or below and downgrading Nigeria (-4) and the DR. Congo (-7) in the process.
By pointing this out, I’m warning honest researchers and laymen about the dangers of relying on data resulting from undisclosed, unsystematic and un-replicable methodology. And although my estimates do not result from any actual IQ measurement beyond the relationship between IQ and schooling evidenced in Norwegian cohorts, my method uses a single, universal conversion factor applied to representative official data collected by professional demographers whereas Lynn’s and the likes’ cherry-picking of samples is only the hobby of a dozen scholars and pseudo-scholars. This is how I found out strong, consistent and meaningful correlations between IQ and various development variables.
Although they are likely more representative of the worldwide distribution of cognitive ability, my estimates still provide evidence that a large part (the largest part, actually) of the world’s population scoring below one standard deviation on Western-normed IQ tests, which is the case for 11 of the world’s 20 most populated countries. Although this may sound alarming, with Pakistan and Ethiopia scoring in the range of mental disability (70 and 66 respectively), I think this effect comes from using Western populations as a reference for standardization.
In fact, another picture emerges when we compare countries with the world’s average, replacing the eurocentric British Greenwich IQ of 100 by an universal IQ of 84 and thus giving a more accurate idea of what is normal cognitive ability by the standards of humanity. In this sample, China, the Philippines and Indonesia are representative of the top of the bell curve whereas Ethiopia, the United States and Germany are the only outliers left with respective Universal IQs of 81.6, 115.6 and 116.6. For this reason, I recommend the use of Chinese or South-East Asian normalization samples in international IQ comparisons.
Does Exogenous Oxytocin Make Xenophobic People Non-Xenophobic?
Oxytocin (OXT) is known as ‘the love hormone’, since it facilitates bonding from mother to child (Galbally et al, 2011; Feldman and Bakermans-Kranenburg, 2017), facilitates childbirth and breastfeeding (since OXT is released in large amounts after nipple stimulation) (Magon and Kalra, 2011), and increases trust in humans (Kosfeld et al, 2005). It is also implicated in some psychiatric disorders (Marrazziti and Del’Osso, 2008; Cochran et al, 2013). OXT, furthermore, also has endocrine and paracrine roles in male reproduction (Nicholson, 1996; Thackare, Nicholson, and Whittleson, 2006), so it is not strictly ‘a female hormone’ (Saladin, 2010). The hormone induces numerous important behaviors that attach the mother—emotionally speaking—to her new child.
A recent study published back in July titled “Oxytocin-enforced norm compliance reduces xenophobic outgroup rejection” (Marsh et al, 2017), purports to observe that, xenophobic individuals administered a nasal spray with OXT and then shown pro-social behaviors to other ethnies (refugees) show a reduction in xenophobic attitudes. First, I will cover the science aspect of it, then, I will cover the ideological aspect of the paper, and finally will address the societal implications this paper may have in the future. I will conclude with my thoughts on both the science and ideology behind the paper (because, in my opinion, there was a clear ideological drive behind the paper, though, the same holds for most other fields).
In the first experiment, 53 males and 23 females (n=76) were given either the spray with the OXT or a placebo. They were then administered a test that tested how high they scored on a ‘Xenophobia index’. Marsh et al (2017: 9,318) write:
In a separate screening session, we evaluated xenophobia by measuring the attitudes toward refugees based on an adapted assessment instrument developed by Schweitzer and colleagues (33). Adaptions encompassed the wording; for example, “Australian refugee” was replaced by “German refugee.” The assessment instrument contained two inventories, in which participants indicated how strongly they associate refugees with realistic and symbolic threats.
The realistic threat scale items encompass different threat perceptions; for example: “Refugees are not displacing German workers from their jobs” or “Refugees have increased the tax burden on Germans.” Responses were coded on a 10-point Likert scale, ranging from 1 (“I strongly disagree”) to 10 (“I strongly agree”). All items were recoded such that higher values reflected greater feelings of perceived realistic threats. The term Xi index, which we used for subsequent analyses, refers to a subject’s mean score achieved on the realistic threat inventory.
Higher Xi scores imply that an individual is more xenophobic. For experiment 1, they put the subjects into a lecture hall to establish altruistic norms, which enabled reputation pressures if one was seen to not be generous when giving. Marsh et al (2017) discovered that those who donated to refugees donated 19 percent more money. Further, donations to natives or refugees—including outgroup bias—was not dependant on gender. The bias (19 percent more donation) indicated altruistic actions and was lowest in those with high Xi scores.
Experiments 2 and 3 were randomized controlled trials (RCTs) of a random sample of 107 males (mean age of 24). They were administered either the OXT nasal spray or a placebo by a blind researcher. They separated them into high Xi scorers or low Xi scorers (n=53 and n=54 respectively). The OXT administered to low Xi scorers specifically increased altruistic behavior towards the ingroup and outgroup “evident in a 68% (outgroup) and an 81% (ingroup) increase in the donated sums” (Marsh et al, 2017: 9315). However, this effect was not noticed in high Xi scorers, so the researchers wondered if showing pro-social behaviors after being administered OXT would show a change in xenophobic behavior.
So people who scored high on the Xi index and were administered OXT showed no change in altruistic behavior. However, when those who scored high on the XI index were administered OXT and prosocial behavior to the outgroup was seen by those with higher Xi scores, they increased their donations to the outgroup by 74 percent.
Figure 1 shows, clearly, that those who were administered OXT and were exposed to altruistic norms from co-ethnics to the outgroup showed more generosity towards the outgroup than those administered the placebo. It’s also worth noting that these findings (of course) are not generalizable to women.
How does ideology affect this? Of course, both the Right and Left can use this study for their own agendas, but, of course, the Marsh et al (2017) may have biases themselves (everyone has biases, even the most well-known, most respected scientists), so now I will look at the ideology behind this paper through both a Right and Left lens, since political bias permeates our every day lives, and due to this, people won’t be able to think rationally about things, ironically, using their emotions to guide their thought processes/conclusions.
Marsh et al (2017: 9317) write:
The effect of solutions combining selective enhancement of OXT signaling and peer influence would be expected to diminish selfish motives, and thereby increase the ease by which people adapt to rapidly changing social ecosystems. More generally, our results imply that an OXT-enforced social norm adherence could be instrumental in motivating a more generalized acceptance toward ethnic diversity, religious plurality, and cultural differentiation resulting from migration by proposing that interventions to increase altruism are most effective when charitable social cues instill the notion that one’s ingroup shows strong affection for an outgroup. Furthermore, UNESCO has emphasized the importance of developing neurobiologically informed strategies for reducing xenophobic, hostile, and discriminatory attitudes (47). Thus, considering OXT-enforced normative incentives in developing future interventions and policy programs intended to reduce outgroup rejection may be an important step toward making the principle of social inclusion a daily reality in our societies.
This seems pretty bad to me. “If you won’t accept people in your countries, you must take this exogenous OXT while watching your ethnic group show altruistic behavior towards the outgroup so then you too will no longer be a ‘racist’.”
In regard to ref 47, it is a 2001 UNESCO address on ‘racism’. Of course, it begins by stating that “Science – modern genetics in particular – has constantly affirmed the unity of the human species, and denied that the notion of `race’ has any foundation.” This, as regular readers know, is false. Race is a social construct of a biological reality. Self-reported race is a great metric to gauge geographic ancestry (Risch et al, 2002), while Tang et al (2005) showed that self-reported race correlated almost perfectly with geographic ancestry. Though I can forgive this since it is a 2001 address.
Here is the money quote (emphasis mine):
Similarly, respect for others and acceptance of the right to be different should be built in the minds of human beings to replace hostile, discriminatory and xenophobic attitudes.
So it seems that Marsh et al (2017) is the first step in UNESCO’s quest for “[building] the minds of human beings to replace hostile, discriminatory and xenophobic attitudes … I can assure you that UNESCO will work actively to achieve this goal in close cooperation with other UN bodies and specialised agencies, other intergovernmental and nongovernmental organizations and with all interested partners.“. This screams social engineering to me, and it seems that the authors would approve of this, especially if you read the Discussion of the paper. This seems to be whatever the Left thinks would make for a better society, they’ll attempt to enact it. People believe they’re the opposite sex? Give them ‘gender-affirming surgery’ (whatever that means). People are ‘racist’? Better strap them down into a chair and shoot exogenous OXT up their nose while their eyes are forced open while watching videos of prosocial behaviors to the outgroup! The numerous possible scenarios that can be thought up due to this paper are mind boggling. For instance, maybe they can use our Internet history and see who the ‘wrongthinkers’ are to forcibly administer OXT to the ‘racists’. But I thought people should be who they are….?
I’d like to know what the baseline levels of OXT in the subjects were. For instance, did the people who had a high Xi score have higher levels of endogenous OXT? Furthermore, were they around people who did not show altruistic behavior towards ‘refugees’? That, then, would show that higher levels of endogenous OXT combined with non-altruistic behavior would increase ethnocentrism (Dreu et al, 2010). OXT has also been called by journalists ‘the love and trust hormone‘ and ‘the cuddle hormone‘, however, the results of Dreu et al (2010) call this into question showing that the hormone may be a cause of inter-group violence along with outgroup derogation. Dreu et al (2010) also conclude that OXT contributes to prosocial behaviors for the ingroup and facilitates outgroup derogation.
So OXT doesn’t make us prosocial on its own; OXT functions as a way to differentiate the ingroup vs. the outgroup, along with giving the in-group more preferential treatment (though other analyses fail to find that outgroup trust decreases; IJzendoorn and Bakermans-Kranenburg, 2011). Dreu et al (2010) also states that ethnocentrism that’s driven by high levels of endogenous OXT “paves the way for intergroup bias, conflict, and violence.” However, the results of Marsh et al (2017) show that OXT may facilitate prosocial behavior.
This study—especially with the discussion and the authors’ citation of the 2001 UNESCO address about “[building] the minds of human beings” is pretty scary. If you don’t go by what society says is ‘good’ and ‘right’ (whatever that means), you’re a heretic and you must be shown the way—forced OXT and watch the altruistic behavior, you don’t want to be ‘racist’ now, do you? We know that those that run our Western countries would like to make us how they think we should be—non-‘xenophobic’, accepting of migration, and they don’t want use to complain about it. So why not attempt to social engineer the populace into conforming to what the government wants?
Of course, over the past decade or so, mass immigration from outside the West has increased. I won’t go into the causes for that since I don’t discuss politics, however, unchecked immigration—no matter what the ultimate cause is—will change the host society. Go somewhere for X amount of benefits? If enough migration occurs to that nation and the native population is displaced enough, how would those benefits continue if those that migrated still exhibit the same behavior they did in their native countries?
This seems to be the start of “If we don’t like what you think or your beliefs, we will attempt to administer hormones to you and force you to watch this in order to cure you of your unnatural (in our egalitarian society) ‘racism’.” Measures such as this have, as far as I know, been spoken about since the turn of the last millennium and the completion of the Human Genome Project. It seems that as more and more migration occurs to the West, more and more anti-migrant attitudes will be had. The plan here seems to be to socially engineer people to be accepting of their replacement. Why? I thought that people should ‘be themselves’, that’s what they tell transgenders, anyway. Why would ‘racists’ be any different? Oh, because it’s not acceptable in today’s increasingly multi-ethnic society.
I won’t go down the path of the naturalistic fallacy (re: ethnocentrism is good and natural because we evolved that way), however, there is, of course, great adaptive significance to such behavior. If you show more altruistic behavior towards the in-group, you’re more likely to show more altruistic behavior to your family members and thusly have a better chance of protecting co-ethnics.
This is a great example of people attempting to enact policies to socially engineer people, a la Brave New World or 1984. Hormones influence behaviors, yes. Further, watching similar others engage in an action facilitates the possibility that they would also take t at same action. Administering exogenous OXT while seeing that would, according to Marsh et al (2017), cure ‘racism’ and make people happy about being displaced in their own countries. Non-Western people are abnormal to our societies, and when migration occurs to the West, this leads to a decrease in social trust in the native population (Putnam, 2007).
The paper (and its results) seem heavily driven by political bias. Will these political biases doom us to further social engineering through administering the populace with whatever hormones are discovered to do what ‘they‘ (the government) want us to do and how ‘they‘ want us to act? All I know is that it’s pretty scary to hear that this is even being talked about. I hope this never comes to fruition.
