Is sociopathy an illness? We often think so … to the point that the word “sick” has taken on a strange secondary meaning. If we call a ruthless, self-seeking person “sick,” we mean he should be shunned at all costs. We don’t mean he should take an aspirin and get some rest.

Sociopathy doesn’t look like a mental illness, being much less incapacitating than schizophrenia and most mental disorders. A sociopath can deal with other people well enough, perhaps too well. As Harpending and Sobus (2015) point out:

It is a psychopathology because of what sociopaths do to us, and it has significant legal, political, and moral consequences for all of us. Most criminals are probably sociopaths according to some definition (the figure of 80% is often quoted).

Sociopaths regularly present the following characteristics:

  • onset before age 15, childhood hyperactivity, truancy, delinquency, disruption in school
  • early and often aggressive sexual activity, marital histories of desertion, non-support, abandonment
  • persistent lying, cheating, irresponsibility without visible shame
  • sudden changes of plan, impulsiveness, unpredictability
  • charm and a façade of sensitivity
  • high mobility, vagrancy, use of aliases

Sociopaths follow a life strategy that is adaptive for themselves but ruinous for society. Harpending and Sobus (2015) argue that they succeed so well because they know how to manipulate social relationships to their advantage.

Sociopathy is at least moderately heritable (Hicks et al., 2004). Interestingly, it seems to cluster with hysteria in first-degree relatives, with sociopathy being expressed in the males and hysteria in the females. Harpending and Sobus (2015) argue that “hysteria is the expression in females of the same genetic material that leads to sociopathy in males.” In short, “sociopathy in females is the result of a greater dose of the genetic material that leads, in smaller doses, to hysteria, namely, hysteria is mild sociopathy.”

If sociopathy is adaptive, why does it affect only a minority of us? It seems that the rest of us have developed counter-strategies of looking for signs of sociopathy and expelling suspects from society … and the gene pool. This is probably why sociopaths tend to be always on the move—if they stay too long with the same people, they risk being detected and dealt with.

Gene-culture coevolution

We adapt to our cultural environment as we do to our natural environment. More so in fact. The last 10,000 years have seen far more genetic change in our ancestors than the previous 100,000, this speeding up of evolution being driven by the entry of humans into an increasingly diverse range of cultural environments.

Sociopathy may thus propagate itself more easily in some cultures than in others, with the result that its incidence may likewise differ from one to another. In a small band of hunter-gatherers, a sociopath will not last long because he is always interacting with the same small group of people:

In a 1976 study anthropologist Jane M. Murphy, then at Harvard University found that an isolated group of Yupik-speaking Inuits near the Bering Strait had a term (kunlangeta) they used to describe “a man who … repeatedly lies and cheats and steals things and … takes sexual advantage of many women—someone who does not pay attention to reprimands and who is always being brought to the elders for punishment.” When Murphy asked an Inuit what the group would typically do with a kunlangeta, he replied, “Somebody would have pushed him off the ice when nobody else was looking.”(Lilienfeld and Arkowitz, 2007)

In a larger community, a sociopath may evade detection long enough to reproduce successfully and pass on his mental traits. Finally, in some cultures he can use his manipulative skills to dominate the community, becoming a “big man” and enjoying very good opportunities for reproduction.

This Pandora’s Box was opened when humans gave up hunting and gathering and became farmers. First, farming supported a much larger population, so it became easier for sociopaths to move about from one group of unsuspecting people to another. Second, farming created a food surplus that powerful individuals could use to support underlings of various sorts: servants, soldiers, scribes, etc. There was thus a growing class of people who did not directly support themselves and whose existence depended on their ability to manipulate others.

Finally, in the tropical zone, farming greatly increased female reproductive autonomy. Through year-round farming, women could provide for themselves and their children with less male assistance. Men accordingly shifted their reproductive strategy from monogamy to polygyny, i.e., from providing for a wife and children to inseminating as many women as possible. This kind of cultural environment selected for male seducers and manipulators rather than male providers. Conversely, it selected for women who feel only an intermittent need for male companionship and who from time to time are able to coax assistance from people who are not so inclined:

Ethnographic descriptions of women who live in social contexts of low male parental investment portray women who are very demanding. Young women demand help from kin on behalf of children. When the help is not forthcoming the mothers often summarily dump or deposit the child or children at the door of a relative who (in their judgment) will not turn the children away. Women demand gifts from boyfriends for themselves.(Harpending and Draper, 1988)

In women, this selection pressure favors a condition known medically as Briquet’s syndrome and more commonly as “hysteria”:

When males are not good risks for parental investment, females will adjust their behavior accordingly. A common clinical characterization of Briquet’s syndrome is a woman who exaggerates need, who demands high levels of attention and investment, who deceives herself and others as to her requirements. The strategy (learned or inherited) makes sense for a woman with high exposure to low investment males. These males, however, are so fickle and so mobile that they can be dunned only in the short run.(Harpending and Draper, 1988)

Sociopathic behavior, be it hysteria or full-blown sociopathy, is not favored in hunter-gatherers, since both sexes invest heavily in their offspring and in each other. The selection is for men and women who can bond strongly with one partner:

[...] abandonment of the pair bond by either partner is likely to be deadly for the offspring. Draper (manuscript) finds that men with more children spend more time hunting than men with fewer dependents; that is to say that more offspring are directly translated into more parental work for the male. Pennington and Harpending (manuscript) found that infant mortality among women who had more than one mate during their reproductive careers was nearly twice as great as infant mortality of women who had only one husband. [...] In societies of this type the contexts for the anti-social trait are unfavorable. There will be no pay-offs for anti-social behavior and the bearer of the trait will be readily detected and ostracized. (Harpending and Draper, 1988)

Strategy and counter-strategy

Sociopathy is therefore not an illness but a strategy. It has been least successful in small societies where both sexes invest heavily in care for their partners and offspring. It has been more successful in larger societies, particularly those where men invest less in partners and offspring. Indeed, because sociopathy does so well in such contexts, it may have hindered the development of larger and more complex societies.

In most large societies, people seek out and expel sociopaths from their local kin group and treat everyone else with suspicion. The result is the “amoral familialism” we see throughout much of the world. People prefer to deal with relatives, hire only relatives for their businesses and, as a rule, act morally only towards relatives. Thus, the high-trust environment of the family cannot extend to society in general. Among other things, this is why the market economy has failed to develop spontaneously over most of the world and over most of history. Without strong-armed government intervention (military pacification, police, courts, etc.), markets remain marketplaces—places of exchange that are highly localized in space and time. The market principle cannot spread to most economic transactions.

Some humans have resolved this problem by freeing themselves from the straitjacket of kinship, by adhering to social rules that apply to everyone, and by ruthlessly expelling rule breakers wherever they may be. This is the adaptation that Europeans have developed to the north and west of the Hajnal line. The relative weakness of kinship ties and, correspondingly, the relative strength of individualism favored a complex of psychological traits that may be summarized as follows:

- capacity to internalize punishment for disobedience of social rules (guilt proneness).

- capacity to simulate and then transfer to oneself the emotional states of other people, especially when such people are affected by rule-breaking either by oneself or by others (affective empathy).

- tendency to frame moral rules in universal, absolute terms, i.e., moral universalism and moral absolutism, as opposed to situational morality based on kinship. Rule-breakers are likewise condemned in absolute terms and may be expelled from the entire community, as opposed to being ostracized by close kin.

The above mental package brought Northwest Europeans closer than other humans to the threshold where one could escape the limitations of kinship and organize society along other lines, notably the market economy, the modern State, and political ideology. It thus became possible to meet the challenge of creating larger societies while ensuring compliance with social rules and a high degree of personal autonomy.

Black metal is a musical subgenre that grew out of death metal and, more broadly, heavy metal. In general, it pushes certain aspects of this genre to even farther extremes: fast tempos, shrieking vocals, and violent stage acts. Black metal bands can be found almost anywhere—Europe, North America, East Asia, even Indonesia and Israel.

In one country, however, it has developed differently, taking violence off-stage and into the political arena. That country is Norway. In the early to mid-1990s, black metallists launched a wave of arson attacks on churches, including one dating from the 12th century. By 1996 there had been 50 church burnings, with similar attacks spreading to Sweden.

Those convicted showed no remorse, and lack of remorse still prevails among many in the black metal scene:

Many, such as Infernus and Gaahl of Gorgoroth, continue to praise the church burnings, with the latter saying “there should have been more of them, and there will be more of them”. Others, such as Necrobutcher and Kjetil Manheim of Mayhem and Abbath of Immortal, see the church burnings as having been futile. Manheim claimed that many arsons were “just people trying to gain acceptance” within the black metal scene. Watain vocalist Erik Danielsson respected the attacks, but said of those responsible: “the only Christianity they defeated was the last piece of Christianity within themselves. Which is a very good beginning, of course”.(Wikipedia, 2015b)

Why this hostility to Christianity? And why is it more extreme in Norway? These questions are raised in a review of black metal around the world:

Individualistic and anti-Christian rhetoric is common across the American death metal scene, and metal bands worldwide look to native traditions as a means to combat cultural hegemony [...], yet nothing on the scale of the crimes in Norway has occurred elsewhere. (Wallach et al., 2011, p. 198)

One reason is the role of organized religion in Norwegian life. Although there are other denominations, the Church of Norway is the leading one and receives State support. Despite recent legislation in 2012 to weaken this relationship with the State, all clergy remain civil servants, the central and regional church administrations remain part of the state administration, all municipalities must support the Church of Norway’s activities, and municipal authorities are still represented in its local bodies (Wikipedia, 2015a)

As either a partner or a rival of the government, the Church of Norway has helped to make public policy: first, the postwar expansion of the welfare state and, later, the boycotts against South Africa. Now, it is leading the push for large-scale non-European/non-Christian immigration, which began in the early 1990s through the “sanctuary movement.” By 1993, as many as 140 congregations were housing 650 Albanians from Kosovo. By reframing immigration in moral terms, the Church made it that much harder to place limits on it, since morality is normally perceived in absolute terms, e.g., murder is always wrong, and not wrong within limits (Lippert and Rehaag, 2013, pp. 126-129).

After a lull, this movement is once more on the upswing:

As the group of unreturnable refugees in Norway has risen over recent years, churches have again become places for public appeals for these groups, through hunger strikes, tents camped as protest at the walls of central churches, and asylum marches following old pilgrimage paths. (Lippert and Rehaag, 2013, p.129).

The Church of Norway is now working with Lutherans elsewhere in Northern Europe to facilitate immigration from Africa and the Middle East. At a meeting this year in Trondheim, the Lutheran World Federation pushed for three measures: expansion of Italy’s Mare Nostrum initiative to the entire Mediterranean; creation of “safe passage” corridors for migrants; and “just distribution” of migrants within Europe (Anon, 2015).

Norway is not the only country where churches have been promoting African and Muslim immigration, but church involvement is especially pivotal there and in Scandinavia as a whole. Because immigration was very limited until recent decades, it is legitimized much more by Christian universalism than by a pre-existing tradition of immigration, as in the United States, Canada, and France. A second reason is the relative dominance of one State-supported church and the unthinking adherence of most Scandinavians, even atheists, to the Lutheran tradition. Thus, in comparison to other predominantly Christian societies, they can more quickly reach a policy consensus, or have one imposed on them.

When a stage act leaves the stage

This was the social context that radicalized Norway’s black metal scene, causing it to go beyond the fake violence of stage performances. Wallach et al. (2011, p. 196) argue that the acts of arson had their roots in “disaffection and alienation from the dominant society,” which many musicians tried to channel into “an extended campaign to return Norway to an idealized pagan past through acts of destruction.”

That campaign failed. It foundered on the movement’s nihilism and contempt for ordinary men and women. “Extreme metal in general does not lend itself well to inciting social change beyond its own scene, since the lyrics are frequently indecipherable and the musical characteristics are often confounding to the uninitiated listener” (Wallach et al., 2011, p. 196). Moreover, as a haven for disaffected people, the metal scene tended to attract loners, exhibitionists, and other misfits. Though perhaps better at seeing through the lies of mainstream society, they lacked the social skills to win the mainstream over to their point of view.

There were of course other reasons why they failed to win over the mainstream. The burning of historic churches antagonized Norwegians in general, including traditionalists and even many black metallists, thus making it easier for the police to crack down and sentence key individuals to lengthy prison terms. Commercial success caused others to become apolitical: “many black metal musicians are now attempting to focus on their actual music and do not want that to be overshadowed by social and political activism” (Wallach et al.,2011, p. 196).

Today, the black metal scene exists mostly as a weird subgenre:

Isolated acts of vandalism still occur, and some in the scene, like Gaahl of Gorgoroth, still engage in violence. Yet the incendiary rhetoric frequently leveled at Western urban society, multiculturalism, and Christianity has not produced the uprising and pagan resurgence that some in the scene claim to desire. (Wallach et al., p. 196)

And Breivik?

It would be tempting to see the church burnings as a prelude to Anders Breivik and the 2011 Norway attacks. Yet, by his own account, Breivik was never into black metal, preferring hip-hop instead. In his manifesto, he disparaged the Oslo metal scene as quiet and law-abiding, an indication that the church burnings had limited support even within that subculture.

[...] As for the right wing community at that time, it was simple. They loved metal and we loved hip-hop. Being into the very small right wing community or the larger mainstream rock community meant Goth girls and hard rock. I disliked both. The big irony was that they; Edward and his friends, were a lot more “normal” than us during this period. They were peaceful while we were violent. They followed the law and rules while we broke the law and ignored the rules again and again. At the same time, the hip-hop community was cheered by the media, praised as the pinnacle of tolerance among the new generation, while THEY were condemned for their political views, systematically harassed and beaten by non-white gangs, extremist Marxist gangs (Blitz etc) and the police. (Berwick, 2011)

During this time of his life, he saw young Muslim men as role models and looked down on “ethnic Norwegians” as sissies:

If I ever got in to trouble I expected my friends to back me up 100% without submitting or running away, as I would for them. Very few ethnic Norwegians shared these principles. They would either “sissy out”, allow themselves to be subdued or run away when facing a threat. [...] The majority of people who shared these principles of pride was the Muslim youths and the occasional skinhead.

In time, Breivik became disenchanted, eventually leaving the hip-hop milieu after a personal incident. The more he associated with Muslims and antifas, the more his respect for them became a simple matter of “necessity”:

In Oslo, as an ethnic Norwegian youth aged 14-18 you were restricted if you didn’t have affiliations to the Muslim gangs. Your travel was restricted to your own neighbourhoods in Oslo West and certain central points in the city. Unless you had Muslim contacts you could easily be subject to harassment, beatings and robbery. Our alliances with the Muslim gangs were strictly seen as a necessity for us, at least for me. We, however, due to our alliances had the freedom of movement.

In short, there is no reason to believe that the black metal scene helped to push Breivik toward his terror attacks. The only elements common to both are Norway itself, its policy of demographic change, and the weak hold of mainstream culture on marginal individuals.

Conclusion

Aside from a few frozen islands and a brief claim to part of Greenland, Norway never had a colonial empire. Nor was it ever involved in the slave trade. Yet, today, the average Norwegian feels more guilt over having white skin and more deference toward dark-skinned people than do citizens of most European countries, including former colonial powers. This is a relatively recent development, being postwar and mostly post-1960—a time when Norway and other Scandinavian countries were striving to assimilate modern Western values, including antiracism.

Scandinavians have been very good at internalizing and acting out those values. They are like model students who have learned to outdo their teachers. This partly reflects—ironically—their cultural homogeneity and their ability to reach consensus and act collectively with little foot-dragging.

This also reflects certain profound psychological traits that characterize Northwest Europeans in general, with Scandinavians forming the epicenter. To the north and west of the Hajnal line, Europeans have long had weaker kinship ties and correspondingly stronger individualism. This social environment has in turn favored a greater emphasis on absolute, universally applicable rules, combined with a stronger desire to expel rule breakers. This system of morality differs from the relativistic, kin-based morality that prevails elsewhere in the world, where right and wrong are more a matter of whose side you are on … and who does what to whom.

Moral universalism and moral absolutism have brought many benefits. They have enabled Northwest Europeans to free themselves from the limitations of kinship and build large high-trust societies that leave greater room for the individual. But such societies have an Achilles heel. They are vulnerable to people who play by a different rule book, be they native deviants who practice “selfishness for me and selflessness for thee” or immigrants from low-trust, kin-based societies … in short, the majority of humans on this planet.

In the past, this was no problem because Norway received few immigrants and because rule breakers of any origin were ruthlessly ostracized. Over the past half-century, however, Norwegians have been persuaded that the supreme rule is Thou shalt not be racist. It follows, therefore, that racists are supreme offenders who must be expelled from society, like witches and heretics of another age. A psychological mechanism that once enabled Norwegian society to perpetuate itself has been reprogrammed to ensure its self-liquidation.

That outcome is not far off. In a country of five million or so, it doesn’t take long to elect a new people. Even remote Arctic communities like Narvik are starting to look like a cross between Mogadishu and Karachi. Will Norwegians stop before it’s too late?

Stopping means dismantling the moral consensus that has legitimized this massive demographic change. But how? Violence simply confirms the judgment that racism is evil. This is what happened after the church burnings and the attacks of 2011. A moral consensus can be dismantled only by moral means …by denouncing it openly and nonviolently.

That won’t be easy. No one wants to be a “bad” person, and in a conformist society like Norway a rule-breaker is “bad” no matter how stupid the rule may seem. As long as the rule is affirmed and never challenged, people will obey and make others obey. Only when enough people challenge it—openly and defiantly—will the moral consensus weaken and collapse. To get from here to there will be difficult but it can be done. Rules of sexual morality were deconstructed. Why not antiracism?

Finally, Norwegians should remember the cost of being “good.” A “good” member of a death cult will die just as surely as a “bad” member. And that is exactly what antiracism has become for Norway. A death cult.

I’ve published an article on the evolution of long head hair in humans. The following is the abstract:

In many humans, head hair can grow to a much greater length than hair elsewhere on the body. This is a “derived” form that evolved outside Africa and probably in northern Eurasia. The ancestral form, which is frizzier and much shorter, survives in sub-Saharan Africans and in other groups whose ancestors never left the tropics. This original hair form is nonetheless relatively straight and silky during infancy. Head hair thus seems to have lengthened in two stages: 1) retention of the infant hair form at older ages; and 2) further lengthening to mid-back and even waist lengths. These changes seem to have gone farther in women, whose head hair is thicker and somewhat longer. The most popular evolutionary explanations are: 1) relaxation of selection for short hair; and 2) sexual selection for women with long hair. Neither hypothesis is satisfactory. The first one cannot explain why head hair lengthened so dramatically over so little time. The second hypothesis suffers from the assumption that some populations have remained naturally short-haired because they consider long-haired women undesirable. Almost the opposite is true in traditional African cultures, which have a long history of lengthening and straightening women’s hair. It is argued here that sexual selection produced different outcomes in different populations not because standards of beauty differed but because the intensity of sexual selection differed. In the tropical zone, sexual selection acted more on men than on women and was thus too weak to enhance desirable female characteristics. This situation reversed as ancestral humans spread northward into environments that tended to limit polygyny while increasing male mortality. Because fewer men were available for mating, women faced a more competitive mate market and were selected more severely.

Religiosity is moderately heritable—25 to 45% according to twin studies (Bouchard, 2004; Lewis and Bates, 2013). These figures are of course underestimates, since any noise in the data gets classified as ‘non-genetic’ variability. So the estimates would be higher if we could measure religiosity better.

But what does it mean to be religious? Does it mean adhering to a single organized religion with a clergy, a place of worship, and a standardized creed? This definition works fairly well in the Christian and Muslim worlds, but not so well farther afield. In East Asia, people often have more than one faith tradition: “If one religion is good, two are better.” Moreover, ‘religion’ has never controlled East Asian societies to the extent that Christianity and Islam have controlled theirs, as Francis Fukuyama notes in The Origins of Political Order. This word becomes even more problematic in simple societies. Did hunter-gatherers have religion? If we take the example of the Inuit, they believed in spirits of various kinds, but those spirits were indifferent to humans and their concerns, being not at all like the fellow in the Christmas jingle:

He sees you when you’re sleeping.

He knows when you’re awake.
He knows if you’ve been bad or good,
So be good for goodness sake!

Simple hunter-gatherers had no idea that a moral God exists. Nor did they see morality as being absolute or universal. A human action could be good or bad, depending on who was doing what to whom. Morality could not be separated from kinship. Your first moral obligation was to yourself, then to your family, then to your close kin. Beyond, who cares?

So what exactly is the heritable component of religiosity? Or should we say components? These questions were addressed by a recent twin study, which concluded that “religiosity is a biologically complex construct, with distinct heritable components” (Lewis and Bates, 2013). The most important one seems to be ‘community integration,’ which is the desire to be among people who befriend each other and help each other on a regular basis. Much research shows that religious people have stronger social needs than the rest of us, and they tend to lose interest in religion when such needs are no longer met. When former Methodist church members were asked why they left their church, the most common response was their failure to feel accepted, loved, or wanted by others in the congregation (Lewis and Bates, 2013).

The second most important component seems to be ‘existential certainty’—belief in a controlling God who will ultimately take care of everything. Belief in divine control reduces anxiety and actually increases one’s sense of personal control. As such, it provides “an epistemic buffer from a range of factors such as unpredictability, instability, and concerns over mortality that exist in this world.”

In sum, this study found that community integration accounts for 45% of innate religiosity and existential certainty for 11%. These two components represent most of what we call ‘religiosity.’

Just one thing. The study was done with a sample of Americans who were 85.1% Christian, the rest being mostly atheist, agnostic, or ”no religious preference.” Would the results have been similar with participants from the Middle East, Africa, or East Asia?

I don’t think so. Religiosity, by its very nature, should be very sensitive to gene-culture coevolution. It’s moderately heritable and serves different purposes in different cultural environments. Any one religion will favor its own ways of being and acting, and people who conform will do better than those who don’t. Thus, over successive generations, the gene pool of believers will become characterized by certain predispositions, personality traits, and other heritable aspects of mental makeup. These characteristics will tend to persist even if the believers cease to believe and become secularized.

This point is made by the authors, albeit indirectly. On the one hand, a community of believers will modify their religion to suit their social and existential needs:

[...] religion per-sé may not be the sole organization or system able to fill the niche created by human needs for community and existential meaning. The succession, displacement, and evolution of religions can be viewed in this light as the shaping of religious systems by their adherents to maximize the extent to which their needs are met.

On the other hand, a religion will modify its community of believers by favoring the survival of those with the “right” mindset and by removing those with the “wrong” mindset:

[...] this ”exchangeable goods” notion of religion may fail to acknowledge the tight fit between religious belief and human psychology: ”religious practices and rituals co-evolved with religiously inclined minds, so that they now fit together extremely well.”

In short, Man has made religion in his own image, but religion has returned the favor. In a very real sense, it has made us who we are.

African Americans sleep on average almost an hour less than do Euro Americans. The two groups have mean sleep times of 6.05 hours and 6.85 hours. This finding has recently been discussed by Brian Resnick in National Journal and by our Steve Sailer.

Researchers reject a genetic explanation: “There is a consensus that innate biological differences between blacks and whites are not a factor” (Resnick, 2015). So what is the cause?

One study points the finger at racism: “If you can take out that discrimination piece, the average African-American and the average Caucasian look at lot more similar. [...] “It’s not perfect, but in terms of sleep, a lot of the disparity goes away” (Resnick, 2015).

The study is by Tomfohr et al. (2012). It found that duration of deep sleep and duration of Stage 2 of light sleep correlated in African Americans with perceived discrimination, which is defined as “the extent to which an individual believes that members of his or her ethnic group have been discriminated against in society.”

Nonetheless, as the authors note, sleep duration still differs significantly between African and Euro Americans even when the difference is adjusted for the effects of perceived discrimination. So we are left with a curious finding: two separate causes, one genetic and the other environmental, are producing the same pattern of effects. Both are reducing deep sleep and Stage 2 light sleep in African Americans while not affecting Stage 1 light sleep.

Whenever I see this kind of finding, I start looking for confounds. Is one cause a sock puppet for the other? It may be that perceived discrimination increases with African ancestry. Perhaps African Americans who feel conscious of discrimination also tend to be darker-skinned and more visibly African than those who don’t. This confound has actually been shown by several studies, such as the following:

This study tested the extent to which skin color is associated with differential exposure to discrimination for a sample of 300 Black adults. Results revealed that dark-skinned Blacks were 11 times more likely to experience frequent racial discrimination than their light-skinned counterparts; 67% of subjects reporting high discrimination were dark-skinned and only 8.5% were light-skinned. (Klonoff and Landrine, 2000; see also Keith and Herring, 1991)

Even if perceived discrimination could fully explain the race difference in sleep duration, we still couldn’t exclude a genetic explanation, since the degree of perceived discrimination is confounded with the degree of African ancestry.

In reality, perceived discrimination accounts for only part of the race difference, and since this difference remains significant even if we factor out that putative cause, the most parsimonious explanation is a genetic cause. Only that cause can fully account for shorter sleep duration in African Americans.

Studies in Africa

Another way to solve this puzzle is to look at Africans living in Africa. Do they show the same pattern we see in African Americans?

We know less about sleep patterns in Africa, but what we do know suggests that Africans, too, have shorter sleep duration. When Friborg et al. (2012) studied sleep in Ghanaians and Norwegians, they found that Ghanaians slept about an hour less than do Norwegians on weekends and between a quarter and half an hour less on weekdays. Oluwole (2010) studied sleep in Nigerian undergraduates and found they slept an average of 6.2 hours plus another 70 minutes in the afternoon. This pattern is actually typical in the tropical zone. People prefer to get some sleep when the temperature is at its peak and spend more time awake when it’s more bearable.

But why would this pattern persist in African Americans? Perhaps it’s hardwired to some degree. When siestas become the cultural norm, there is selection for those individuals who enjoy being normal (and against those who don’t).

Sleep patterns are heritable:

Assessed self-reported sleep data from 2,238 monozygotic (MZ) and 4,545 dizygotic (DZ) adult twin pairs born in Finland before 1958. Results indicate a significant hereditary effect on sleep length and on sleep quality. When the data were examined in subgroups defined by sex, age (18-24 yrs and 25+ yrs), and cohabitation status of the twin pair, the highest heritability estimates for sleep length were for Ss living together aged 25 yrs or older. For Ss living apart, the heritability estimates were statistically significant in all Ss aged 25 yrs or older. For sleep quality, significant heritability estimates were found for all groups except women living together. Results indicate that a significant proportion of the variance in sleep length and quality was due to factors that make MZ Ss more similar than DZ Ss. (Partinen et al., 1983)

A single genetic polymorphism seems to explain much of the variability between individuals in sleep patterns, particularly deep sleep and slow wave activity (SWA):

Here we show in humans that a genetic variant of adenosine deaminase, which is associated with the reduced metabolism of adenosine to inosine, specifically enhances deep sleep and SWA during sleep. In contrast, a distinct polymorphism of the adenosine A2A receptor gene, which was associated with interindividual differences in anxiety symptoms after caffeine intake in healthy volunteers, affects the electroencephalogram during sleep and wakefulness in a non-state-specific manner. Our findings indicate a direct role of adenosine in human sleep homeostasis. Moreover, our data suggest that genetic variability in the adenosinergic system contributes to the interindividual variability in brain electrical activity during sleep and wakefulness. (Retey et al., 2005)

Conclusion

So African Americans are getting enough sleep at night. It’s just that they’re not getting enough afternoon naps. But aren’t naps for kids? Or old fogeys? Actually, they’re quite normal for adults in much of the world. In the Nigerian study, 82% of the participants regularly took afternoon naps.

It’s ironic that the “r word” has been injected into this debate. If a behavior deviates from the white American norm, and if racism is held responsible either directly or indirectly, one is assuming that this deviation is pathological. It is “deviant.” It shouldn’t exist and something should be done about it. The white American norm thus becomes a norm for all humans, and all humans—if they want to be fully human—should strive toward it.

In reality, there is no single human nature. Genetic evolution didn’t slow down when humans began to split up and settle the different continents. It accelerated. And not just because our ancestors were adapting to different natural environments. Most of the acceleration took place long after the globe had been settled from the equator to the arctic. It happened when humans began to adapt to an increasingly diverse range of cultural environments. And those adaptations were mostly behavioral and psychological.

One of them is the way we sleep. The African sleep pattern is normal in its native environment. It is simply an adaptation to a particular set of circumstances, just as the northern European sleep pattern is an adaptation to another set of circumstances.

In my last column, I reviewed the findings of Butovskaya et al. (2015) on testosterone and polygyny in two East African peoples:

- Testosterone levels were higher in the polygynous Datoga than in the monogamous Hadza. This difference is innate.

- Datoga men were more aggressive than Hadza men on all measures used (physical aggression, verbal aggression, anger, and hostility)

- Datoga men were larger and more robust than Hadza men

- All of these characteristics seem to be adaptive under conditions when men have to compete against other men for access to women

Testosterone levels were not only higher in the Datoga but also more variable. Alvergne et al. (2009) studied this variability in Senegalese men, finding that the monogamous ones differed from the polygynous ones in the way testosterone levels changed with age. The levels were higher in the polygynous men than in the monogamous men between the ages of 15 and 30. After 45, this pattern reversed: the monogamous men had the higher levels. At all ages, the polygynous men were more extraverted than the monogamous ones, this quality being defined as “pro-social behavior which reflects sociability, assertiveness, activity, dominance and positive emotions.” Extraversion may assist a reproductive strategy of seducing women, rather than providing for them.

Thus, when Africans gave up hunting and gathering for farming, there was selection for a new package of male traits. Some of these traits are physiological (higher testosterone levels), some anatomical (denser bones, greater arm and leg girth; changes to muscle fiber properties, etc.), and some behavioral (polygyny, aggressiveness, extraversion, etc.). But this selection didn’t eliminate older genotypes, at least not wholly. There seems to be a balanced polymorphism that allows a minority of quieter, monogamous men to thrive in a high-polygyny society like Senegal. When polygynous men become too numerous, they may spend too much time looking for mating opportunities and not enough checking up on their current wives to avoid being cuckolded. It might be better for some to live continuously with one wife.

African Americans versus Euro Americans

The above differences within sub-Saharan Africa (Datoga vs. Hadza, polygynous Senegalese vs. monogamous Senegalese) are also seen between African Americans and Euro Americans. In all these cases, the differences are of degree and proportion, rather than absolute and non-overlapping.

Testosterone reaches high levels in young African American adults (Pettaway, 1999; Ross et al., 1986; Ross et al., 1992; Winters et al., 2001). African Americans are also likelier to have alleles for high androgen-receptor activity (Kittles et al.,2001). Lifetime exposure to testosterone is reflected in development of prostate cancer, with African American men having the world’s highest incidences (Brawley and Kramer, 1996). It was once thought that lower incidences prevail among black West Indians and sub-Saharan Africans, but underreporting is now thought to be responsible (Glover et al., 1998; Ogunbiyi and Shittu, 1999;Osegbe, 1997).

In African Americans, blood testosterone levels peak during adolescence and early adulthood, being higher than those of Euro Americans of the same age. Levels decline after 24 years of age, and by the early 30s are similar to those of European Americans (Gapstur et al., 2002; Nyborg, 1994, pp. 111-113; Ross et al., 1986; Ross et al., 1992; Tsai et al., 2006; Winters et al., 2001). This is the same pattern we saw in polygynous Senegalese men versus monogamous Senegalese men. In short, polygyny seems associated with a more exaggerated pattern of variation with age.

The demographic contradictions of a high-polygyny society

Testosterone levels are normally higher in all young men, but why are they higher still when polygyny is common? The reason seems to be the scarcity of available women. High-polygyny societies generate a shortage of mateable women, and this shortage is managed by giving priority to men who are at least ten years past puberty. For instance, among the Nyakyusa: “[...] there is a difference of ten years or more in the average marriage-age of girls and men, and it is this differential marriage-age which makes polygyny possible” (Wilson, 1950, p. 112).

By concentrating celibacy among young men, this age rule compels them to seek sex through warfare or illicit means. According to Pierre van den Berghe (1979, pp. 50-51):

Typically, the more men are polygynous in a given society, the greater the age difference between husbands and wives. [...] The temporary celibacy of young men in polygynous societies is rarely absolute, however. While it often postpones the establishment of a stable pair-bond and the procreation of children, it often does not preclude dalliance with unmarried girls, adultery with younger wives of older men, or the rape or seduction of women conquered in warfare. Thus, what sometimes looks like temporary celibacy is, in fact, temporary promiscuity. These young men often devote themselves to warfare during their unmarried years and sometimes homosexuality is tolerated during that period.

For young men in a high-polygyny society, warfare—typically raids against neighboring communities—is the main way to gain access to women. In a sense, war becomes a means of resolving the demographic contradictions of a high-polygyny society. Polygyny creates a wife shortage among young men, and this contradiction is resolved by turning it outward. As warriors, young men are encouraged to satisfy their sexual urges through raids against neighboring peoples. Warfare thus becomes endemic.

This relationship between polygyny and war has often been noted in studies of African societies:

Dorjahn (1959) says African warfare emphasized taking captives, rather than killing the enemy. Kelly’s discussion of Nuer warfare provides an interesting perspective on this phenomenon. In Nuer warfare the main casualties were younger men and older women, with male and female mortality being almost equal. Younger women and children were captured. Female captives were valued because they could be used to generate bridewealth when they were married to other Nuer, whereas captive boys were adopted into the lineage of their captor and would require bridewealth payment when they married. Consequently, few males were taken captive (Kelly 1985:56-57). (White and Burton, 1988)

In their cross-cultural study of the causes of polygyny, White and Burton (1988) conclude that “polygyny is associated with warfare for plunder and/or female captives”:

[...] polygyny is seen as associated with the expansion of male-oriented kin groups through favorable environments, facilitated by capture of women or bridewealth via warfare. Following this analysis, it is difficult to see polygyny as having benign effects upon the lives of all women. Rather, polygyny produces benefits for senior wives, who have sons and can mobilize the labor of junior wives and children (Hartung 1982); it has negative effects on women who become slaves, captives, or junior wives, or who do not have sons.

We now come to a leading cause of the African slave trade. Polygyny led to warfare, which led to a surplus of unwanted male captives. These captives could be sold as slaves, but local markets would soon be saturated. The excess supply had to be sold farther away, with the result that slave trading networks began to reach the Middle East as early as the time of Christ (Frost, 2008).

While outsiders from the Middle East and Europe would later get more and more involved, becoming not only traders but also captors, it was Africans themselves who initially controlled the supply chain. In its early stages, and even later, this trade was driven by factors internal to Africa.

Contrary evidence

Whenever I discuss this subject, some people will counter that certain studies have shown an absence of racial/ethnic differences in testosterone levels. Let me discuss these studies at some length.

Richard et al. (2014)

This meta-analysis concluded: “After adjustment for age, black men have a modestly but significantly 2.5 to 4.9% higher free testosterone level than white men.” Here, “adjustment for age” means comparing black and white men of the same age. The conclusion isn’t surprising, since African American men have a testosterone advantage only from puberty to their early 30s. At other ages, their testosterone levels are either equal to or less than those of Euro American men.

This meta-analysis has two other flaws. First, it included only studies on “men,” thus excluding studies on teenagers, among whom the race difference is greatest.

Second, it included Rohrmann et al. (2007). This study suffers from serious methodological problems, as I will now explain.

Rohrmann et al. (2007)

This study concluded that “contrary to the postulated racial difference, testosterone concentrations did not differ notably between black and white men.”

This study also found that 45-69 year old black men have higher testosterone levels (5.62 ng/ml) than do 20-44 year old black men (5.35 ng/ml). Such a finding is paradoxical and indicates a faulty dataset. The authors used serum samples from the National Center for Health Statistics that had been earlier collected for its Third National Health and Nutrition Examination Survey (NHANES III). The authors state they used 1,479 samples that remained out of an initial total of 1,998. Over 25% of the original samples were missing. The authors state that some samples were missing because they were being used for another study.

The same serum bank had in fact been used for research on a sexually transmitted disease. This was the study by Fleming et al. (1997), who reported that more than 25% of adults between 30 and 39 years of age were positive for HSV-2 (Herpes Simplex virus type 2). Those samples may have been set aside either for further testing or for legal reasons. The serum bank would have thus lost some of its most polygynous donors.

Ellison et al. (2002)

This study measured salivary testosterone in young men (15-30 years) from the United States, Congo, Nepal, and Paraguay. Americans had the highest levels (335 pmol/l), followed by Congolese (286 pmol/l), Nepalese (251 pmol/l), and Paraguayans (197 pmol/l).

Who were these Americans? They are simply identified as … young Americans—a demographic that is now less than 60% of European descent. In Boston, where the study was conducted, public schools in 2005 were 46% black and 31% Latino (mainly Puerto Ricans and Dominicans). The authors also state that “the USA participants were recruited by public advertisement.” The pool of participants may have therefore resembled that of people who give blood in exchange for payment, i.e., it may have been disproportionately poor and non-white. In any event, the results are unusable without any information on racial background.

The Congolese participants were likewise unrepresentative of Congolese in general. They were Lese who inhabit the Ituri forest in proximity to the Efe pygmies. Many Lese are, in fact, partly of pygmy ancestry. As such, their testosterone levels would be closer to that of hunter-gatherers with lowers levels of polygyny and less male-male competition for mates.

Richards et al. (1992)

This study concluded that testosterone levels did not differ between African American and Euro American boys between the ages of 6 and 18. Such a finding is to be expected for the first few years of this age range, when no difference should exist between the two groups. The main flaw, however, is that the participants were compared not by age but by Tanner stage. Since African Americans enter puberty earlier, this study compared younger African American boys with older Euro American boys.

Testosterone levels may differ between the two groups because of earlier maturation by African American boys. But why would this difference persist beyond adolescence and into the mid-twenties? This question remains unresolved because none of the participants were older than 18.

Various African studies

Several studies have found lower testosterone levels in African populations than in North Americans. This difference might be partly due to the effects of malnutrition or infectious diseases, notably among the Zimbabwean subjects studied by Lukas et al. (2004). The main reason, however, is that these studies mostly had middle-aged or even elderly participants. Lukas et al. (2004) report a mean age of 42.18. The scatter plot (Fig. 2) suggests a logarithmic decline in testosterone with age, but there were too few participants below 25 for analysis of that age group. The same criticism applies to Campbell et al. (2003), a study of testosterone levels in Ariaal pastoralists from northern Kenya. The mean age was 46.8.

In addition, some of these studies concern hunter-gatherers, like the !Kung of Namibia and the Ituri Forest pygmies of the Congo, who have low polygyny rates and weak male-male competition for mates (e.g., Winkler and Christiansen, 1993). Their low testosterone levels are thus to be expected.

Humans differ in paternal investment—the degree to which fathers help mothers care for their offspring. They differ in this way between individuals, between populations, and between stages of cultural evolution.

During the earliest stage, when all humans were hunter-gatherers, men invested more in their offspring with increasing distance from the equator. Longer, colder winters made it harder for women to gather food for themselves and their children. They had to rely on meat from their hunting spouses. Conversely, paternal investment was lower in the tropics, where women could gather food year-round and provide for themselves and their children with little male assistance.

This sexual division of labor influenced the transition to farming. In the tropics, women were the main providers for their families as gatherers of fruits, berries, roots, and other wild plant foods. They were the ones who developed farming, thereby biasing it toward domestication of wild plants.

This may be seen in sub-Saharan Africa, where farming arose near the Niger’s headwaters and gave rise to the Sudanic food complex—a wide range of native crops now found throughout the continent (sorghum, pearl millet, cow pea, etc.) and only one form of livestock, the guinea fowl (Murdock, 1959, pp. 44, 64-68). Many wild animal species could have been domesticated for meat production, but women were much less familiar with them. Men knew these species as hunters but had little motivation to domesticate them. Why should they? Women were the main providers.

And so women shouldered even more the burden of providing for themselves and their offspring. Men in turn found it easier to go back on the mate market and get second or third wives. Finally, men had to compete against each other much more for fewer unmated women.

There was thus a causal chain: female dominance of farming => female reproductive autonomy => male polygyny => male-male rivalry for access to women. Jack Goody (1973) in his review of the literature says: “The desire of men to attract wives is seen as correlated with the degree of women’s participation in the basic productive process.” The more women produce, the lower the cost of polygyny.

In sub-Saharan Africa, the cost was often negative. Goody quotes a 17th century traveler on the Gold Coast: the women till the ground “whilst the man only idly spends his time in impertinent tattling (the woman’s business in our country) and drinking of palm-wine, which the poor wives are frequently obliged to raise money to pay for, and by their hard labour maintain and satisfie these lazy wretches their greedy thirst after wines.”

Goody cites data from southern Africa showing that the polygyny rate fell when the cost of polygyny rose:

In Basutoland one in nine husbands had more than one wife in 1936; in 1912, it was one in 5.5 (Mair 1953: 10). Hunter calculates that in 1911 12 per cent of Pondo men were plurally married and the figure was slightly lower in 1921. In 1946, the Tswana rate was 11 per cent; according to a small sample collected by Livingstone in 1850 it was 43 per cent. The figures appear to have changed drastically over time and the reasons are interesting. ‘The large household is now not a source of wealth, but a burden which only the rich can bear’ (Mair 1953: 19). Not only is there a specific tax for each additional wife, but a man’s wives now no longer give the same help in agriculture that they did before. One reason for this is that the fields are ploughed rather than hoed. Among the Pondo, ‘the use of the plough means that the amount of grain cultivated no longer depends on women’s labour’ (Goody, 1973)

Although polygynous marriage has become less common in southern Africa, polygynous behavior seems as frequent as ever. To a large degree, polygynous marriage has given way to more transient forms of polygyny: prostitution and other informal arrangements. Goody also notes that polygyny rates have remained high in the Sahel, where pastoralism has nonetheless increased male participation in farming. He gives the example of Ghana. Polygyny rates are about the same in the north and the south, yet in the north men participate much more in farming.

So what is going on? Goody concludes that “female farming and polygyny are clearly associated in a general way” but ultimately the “reasons behind polygyny are sexual and reproductive rather than economic and productive.” It would be more parsimonious to say that the polygyny rate increases when the cost of providing for a woman and her children decreases for men. Over time, low-cost polygyny selects for men who are more motivated to exploit sexual opportunities. This new mindset influences the subsequent course of gene-culture coevolution.

Such gene-culture coevolution has gone through four stages in the evolutionary history of sub-Saharan Africans:

First stage

Tropical hunter-gatherers were already oriented toward low paternal investment. Men had a lesser role in child rearing because year-round food gathering provided women with a high degree of food autonomy. Women were thus selected for self-reliance and men for polygyny. Pair bonding was correspondingly weak in both sexes.

Second stage

This mindset guided tropical hunter-gatherers in their transition to farming. In short, female-dominated food gathering gave way to female-dominated horticulture—hoe farming of various crops with almost no livestock raising. Women became even more autonomous, and men even more polygynous. There was thus further selection for a mindset of female self-reliance, male polygyny, and weak pair bonding.

Third stage

A similar process occurred with the development of trade. Female-dominated horticulture tended to orient women, much more than men, toward the market economy. This has particularly been so in West Africa, where markets are overwhelmingly run by women. Trade has thus become another means by which African women provide for themselves and their children.

Fourth stage

Female-dominated horticulture has given way to male-dominated pastoralism in some regions, such as the Sahel. Despite higher male participation in farming, the pre-existing mindset has tended to maintain high polygyny rates. We see a similar tendency in southern Africa, where polygyny rates have fallen over the past century, and yet polygynous behavior persists in the form of prostitution and less formal sexual arrangements.

The Hadza and the Datoga

Mode of subsistence, mating system, and mindset are thus interrelated. These interrelationships are discussed by Butovskaya et al. (2015) in their study of two peoples in Tanzania: the largely monogamous Hadza (hunter-gatherers) and the highly polygynous Datoga (pastoralists). In their review of previous studies, the authors note:

In hunter-gatherer societies, such as the monogamous Hadza of Tanzania (Africa), men invest more in offspring than in small-scale pastoralist societies, such as the polygynous Datoga of Tanzania [12-14]. Polygyny and between-group aggression redirect men’s efforts from childcare toward investment in male-male relationships and the pursuit of additional mates [15]. When men participate in childcare, their testosterone (T) level decreases [15-18]. Muller et al. [19] found that, among the monogamous, high paternally investing Hadza, T levels were lower for fathers than for non-fathers. This effect was not observed among the polygynous, low paternally investing Datoga. (Butovskaya et al., 2015).

Butovskaya et al. (2015) confirmed these previous findings in their own study:

Datoga males reported greater aggression than Hadza men—a finding in line with previous reports [29,30]. It is important to mention several striking differences between these two cultures. There is a negative attitude toward aggression among the Hadza but not among the Datoga. In situations of potential aggression, the Hadza prefer to leave [30]. In contrast, aggression is an instrument of social control—both within the family and in outgroup relations in Datoga society. Datoga men are trained to compete with each other and to act aggressively in particular circumstances [30]

The authors also confirmed differences in reproductive behavior between the two groups:

Our research indicates a difference in the number of children in Hadza and Datoga men achieved after the age of 50. This may be interpreted as differences attributable to different life trajectories and marriage patterns. Beginning in early childhood, boys in the two societies are subjected to different social and environmental pressures (e.g., it is typical for Datoga parents to punish children for misbehavior, while parental violence is much less typical for Hadza parents). Hadza men start reproducing in the early 20s, but their reproductive success later in life is associated with their hunting skills [15]. In the Datoga, men marry later, typically in their 30s. Male status and, consequently, social and reproductive success in the Datoga are positively correlated with fighting abilities and risk-taking in raiding expeditions among younger men, and with wealth, dominance, and social skills among older men. In the Datoga, as in other patrilineal societies, fathers do not invest directly in child care, but children do benefit from their father’s investment in the form of wealth and social protection, as well as various services provided by father’s patrilineal male relatives [56]. In polygynous societies, spending resources on attracting additional wives may be more beneficial [40,57,58]. It would be difficult for some men to invest directly in providing for all their children, given that men with multiple wives can father a considerable number of children, and that households with wives may be located at substantial distance from one another.

This behavioral difference seems to be mediated by differing levels of androgens, such as testosterone:

The effect of androgens, such as T, operates through stimulation of androgen receptors [21-23]. The androgen receptor (AR) gene contains a polymorphic and functional locus in exon 1, comprising two triplets (CAG and GGN). This locus supports a regulatory function that responds to T, with fewer CAG repeat clusters being more effective in transmitting the T signal [22]. Moreover, the length of the GGN repeat predicts circulating and free T in men.

At the androgen receptor gene, the authors found fewer CAG repeats in the Datoga than in the Hadza. The number of repeats was also more variable in the Datoga. The Datoga’s higher and more variable polygyny rates thus seem to correlate with higher and more variable levels of testosterone.

The authors also wished to see whether these differing levels of testosterone correlate with differing levels of aggressiveness. To this end, they interviewed the Hadza and Datoga participants:

They were asked to provide information including their age, sex, marital status, number of children, ethnicity and aggression history (especially fights with other tribal members). All questions were read aloud in one-to-one dialogues and further explanations were provided, if necessary. Self-reported aggression was assessed with the Buss-Perry Aggression Questionnaire (BPAQ; [48]). The BPAQ includes 29 statements, grouped into four subscales—physical aggression (9 items), verbal aggression (5 items), anger (7 items), and hostility (8 items)—answered on aLikert scale anchored by 1 (extremely uncharacteristic of me) and 5 (extremely characteristic of me).

Total aggression was found to correlate negatively with CAG repeat number. Age group did not predict aggression.

More polygyny = stronger sexual selection of men

Finally, the authors suggest that Datoga men, with their higher polygyny rate and fiercer competition for access to women, have undergone greater sexual selection. They have thus become bigger and more masculine than Hadza men. Although this selection pressure also exists among the Hadza, the driving force of sexual selection has been weaker because Hadza men are more monogamous and less sexually competitive:

Our findings are in concordance with other research, demonstrating that even among the relatively egalitarian Hadza there is selection pressure in favor of more masculine men [59-62]. At the same time, preference for more masculine partners, with greater height and body size, is culturally variable and influenced by the degree of polygyny, local ecology, and other economic and social factors [59-62]. Many Datoga women commented that they would like to avoid taller and larger men as marriage partners, as they may be dangerously violent [44,62]. Only 2% of Hadza women listed large body size as an attractive mate characteristic [63]. Hadza marriages in which the wife is taller than the husband are common, and as frequent as would be expected by chance [64]. (Butovskaya et al., 2015)

This is consistent with what we see in nonhuman polygynous species. Successful males tend to be the ones that are better not only at attracting the opposite sex but also at fighting off rivals. They thus become bigger, tougher, and meaner.

This is also consistent with what we see generally in the highly polygynous farming peoples of sub-Saharan Africa. They and their African-American descendants exceed European-descended subjects in weight, chest size, arm girth, leg girth, muscle fiber properties, and bone density (Ama et al., 1986; Ettinger et al.,1997; Himes, 1988; Hui et al., 2003; Pollitzer and Anderson, 1989; Todd and Lindala, 1928; Wagner and Heyward, 2000; Wolff and Steggerda, 1943; Wright et al., 1995).

Until three years ago, Canada’s human rights commissions had the power to prosecute and convict individuals for “hate speech.” This power was taken away after two high-profile cases: one against the magazine Maclean’s for printing an excerpt from Mark Steyn’s book America Alone; and the other against the journalist Ezra Levant for publishing Denmark’s satirical cartoons of the prophet Mohammed. Both cases were eventually dismissed, largely because the accused were well known and popular. As Mark Steyn observed:

[...] they didn’t like the heat they were getting under this case. Life was chugging along just fine, chastising non-entities nobody had ever heard about, piling up a lot of cockamamie jurisprudence that inverts the principles of common law, and nobody paid any attention to it. Once they got the glare of publicity from the Maclean’s case, the kangaroos decided to jump for the exit. I’ve grown tired of the number of Canadian members of Parliament who’ve said to me over the last best part of a year now, “Oh, well of course I fully support you, I’m fully behind you, but I’d just be grateful if you didn’t mention my name in public.” (Brean, 2008)

Despite the dismissals, both cases had a chilling effect on Canadian journalism. Maclean’s made this point in a news release:

Though gratified by the decision, Maclean’s continues to assert that no human rights commission, whether at the federal or provincial level, has the mandate or the expertise to monitor, inquire into, or assess the editorial decisions of the nation’s media. And we continue to have grave concerns about a system of complaint and adjudication that allows a media outlet to be pursued in multiple jurisdictions on the same complaint, brought by the same complainants, subjecting it to costs of hundreds of thousands of dollars, to say nothing of the inconvenience. (Maclean’s, 2008)

This situation had come about gradually in Canada. At first, human rights commissions fought discrimination only in employment and housing, and there was strong resistance to prosecution of people simply for their ideas. This situation changed from the 1970s onward. Human rights took the place in society that formerly belonged to religion, and human rights advocates acquired the immunity from criticism that formerly belonged to the clergy. Discrimination was no longer wrong in certain cases and under certain circumstances. It became evil, and people who condoned it in any form and for any reason were likewise evil.

This view of reality progressively transformed human rights commissions. On the one hand, they were given an ever longer list of groups to protect. On the other, their scope of action grew larger, expanding to include not only the job and housing markets but also the marketplace of ideas. Their power increased until they became a parallel justice system, the key difference being that they denied the accused certain rights that had long existed in traditional courts of law, particularly the presumption of innocence and the right to know one’s accuser. All of this was made possible by section 13 of the Human Rights Act (1977):

Section 13 ostensibly banned hate speech on the Internet and left it up to the quasi-judicial human rights commission to determine what qualified as “hate speech.” But, unlike a court, there was no presumption of innocence of those accused of hate speech by the commission. Instead, those accused had to prove their innocence.(Akin, 2013)

In 2012, the House of Commons repealed section 13. The ensuing three years brought a return to normal and a dissipation of the chill that had descended on Canadian journalists and writers.

Today, our Indian summer is coming to an end. In Alberta, the human rights commission is pushing to see how far it can go, and Ezra Levant is again being prosecuted:

This October I will be prosecuted for one charge of being “publicly discourteous or disrespectful to a Commissioner or Tribunal Chair of the Alberta Human Rights Commission” and two charges that my “public comments regarding the Alberta Human Rights Commission were inappropriate and unbecoming and that such conduct is deserving of sanction.”

Because last year I wrote a newspaper editorial calling Alberta’s human rights commission “crazy”. (Levant, 2015)

Last month in Quebec, the government passed a bill that greatly expands the powers of its human rights commission to prosecute “hate.”

Bill 59, introduced by Quebec Premier Philippe Couillard’s Liberal government, would make it illegal to promote hate speech in Quebec, without defining what hate speech is. Despite this, it would expand the definition of hate speech to include “political convictions” for any speech deemed by Quebec’s human rights bureaucracy to promote “fear of the other”, an absurdly vague term which could easily lead to prosecutorial abuses.

Bill 59 would empower Quebec’s human rights commission to investigate anonymous complaints, or to launch investigations on its own, without any complaint, culminating in charges before Quebec’s Human Rights Tribunal. The tribunal would be able to impose fines of up to $10,000 for first offenders, $20,000 for repeat offenders. Those found to have violated the legislation would be named and shamed on a publicly accessible list of offenders, maintained by the government. (Editorial, 2015)

The new law also casts a wider net by defining two forms of complicity in hate speech, direct and indirect:

Engaging in or disseminating the types of speech described in section 1 is prohibited.

Acting in such a manner as to cause such types of speech to be engaged in or disseminated is also prohibited. (Gouvernement du Québec, 2015)

“Hate speech” is supposedly defined in section 1 of Bill 59, but this section merely repeats the same term:

The Act applies to hate speech and speech inciting violence that are engaged in or disseminated publicly and that target a group of people sharing a characteristic identified as prohibited grounds for discrimination under section 10 of the Charter of human rights and freedoms (chapter C-12).(Gouvernement du Québec, 2015)

In short, “hate speech” will be defined by the Quebec Human Rights Commission, the only limitation being that the speech must target a protected group.

How did this piece of legislation come to be? It had been sold to the public as a means to fight Islamist terrorism and, as such, gained the support of many people, including right-wing politicians who thought its “ant-hate” language was just window dressing to make it more palatable. In its final form, however, there are no references at all to Islamism or terrorism. As columnist Joanne Marcotte points out:

Nowhere in the bill is this goal mentioned. It doesn’t seem that this is the intention of the Liberal Party, which is perhaps more concerned about a supposedly Islamophobic current of opinion than about the pressure that radical religious fundamentalists are exerting on our values of individual freedom.

As Joanne Marcotte notes ironically, this bill was pushed through by a center-right government that claims to believe in individual freedom. Even more ironically, the strongest support for the new law comes from the far left. A demonstration in Montreal against Bill 59 was broken up by a hundred antifas. The police were there but not one antifa was arrested (Kamel, 2015).

This is a growing trend in Western countries: a strange alliance between center-right regimes and far-left antifas. For all intents and purposes, the latter are becoming an extrajudicial police, just as human rights commissions are becoming a parallel justice system.

Conclusion

After a brief lull, a new offensive has begun against “hate speech” in Canada. Quebec is leading the way with legislation that is not only punitive but also broadly-worded. Hate speech is whatever the human rights commission considers to be hate speech.

Outside Quebec, existing laws are likewise being interpreted more punitively and more broadly, as seen in the prosecution of Ezra Levant for “disrespectful” speech. This trend may lead to new legislation in other provinces and perhaps at the federal level, especially if the Liberal Party takes power on October 19.

Although the Liberal Party of Canada is legally distinct from the Liberal Party of Quebec, the two work together and cater to the same clientele. The major difference is that the former defines itself as center-left and the latter as center-right. In practice, the difference is trivial, “left” and “right” referring more and more to the same ideology. Today, the left pushes for cultural globalism (multiculturalism, antiracism), while the right pushes for economic globalism (outsourcing to low-wage countries, insourcing of low-wage labor).

Quebec’s Bill 59 may thus become a template for federal legislation. The Liberal leader, Justin Trudeau, has in fact promised to amend the Human Rights Act while not spelling out his plans, other than to say he will recognize transgendered individuals as a protected group.

So will I be packing my bags and going south of the border? No, I love my country too much and, frankly, I don’t envy Americans. The U.S. doesn’t have anti-hate laws because it doesn’t need them. Most Americans have fully internalized the antiracist ethos and can be counted on to be willing partners in their own dispossession.

The situation is different in Canada, especially in Quebec: the new ethos is more recent, has a weaker hold on people, and cannot be counted on “to do its job.” This is why we have legislation like Bill 59. It’s a sign of weakness, not of strength.

Chanda Chisala has written another piece on IQ and African immigrants to the UK:

One of the biggest problems I had with the commenters were readers who apparently were only exposed to the statistical concept of Regression to the Mean from outside the IQ debate. [...]. The problem is not that the black immigrant children were not regressing to the point of equaling their source population mean IQ (that’s also not what hereditarians predict either), but that they were clearly not even moving (or being pulled) towards that extremely low IQ, as hereditarians predict.

The correct term is not “regression to the mean.” It’s “non-inheritance of acquired characteristics.” In other words, each person has a single genotype and a range of possible phenotypes. A culture can push its members to either limit of this range, thus creating a phenotype unlike that of other people with the same genetic endowment. But this phenotype has to be recreated with each succeeding generation. For instance, there used to be a Chinese custom of binding a girl’s foot to make it four inches long and of limited use for walking. When the custom was outlawed, the next generation of women had normal feet. The phenotype bounced back to its initial form, so to speak, much like an elastic band when you stop stretching it (see note 1).

Regression to the mean is something else. It happens because ofgenetic change. For instance, a man with above-average IQ will likely marry a woman with above-average IQ. But only part of their above-averageness is genetic. The rest is due to favorable circumstances. Or simply luck. So their children’s IQ will likely be a bit closer to the mean of the overall population. That second generation will in turn marry people with similar IQs. And their children will likewise be closer still to the population mean. Eventually, several generations later, the descendants of that original couple will have a mean IQ that matches the population mean.

That’s regression to the mean. It’s a multigenerational genetic change. It’s not what happens when genes stay constant and culture changes.

Chanda is really talking about what happens when a culture stops pushing people to excel. The phenotype reverts to its usual state and the pressure to excel comes only from within. This is a legitimate argument, and it may have great explanatory value. When people from certain cultures move to Western countries, the second and third generations do a lot worse than the first generation over many indicators—academic achievement, crime rates, family stability, etc. This is a frequent outcome when people move from an environment where behavior is tightly controlled by family and community to one where behavior is much more self-controlled.

Such social atomization is less toxic for people of Northwest European descent because they have adapted to it over a longer time. For at least the past millennium, they have had weaker kinship ties and stronger tendencies toward individualism than any other human population. This cultural environment has favored individuals who rely less on external means of behavior control and more on internal means, specifically guilt proneness and affective empathy (Frost, 2014).

But that isn’t Chanda’s argument. That’s the argument he attributes to something called “the HBD position.” In reality, there are at least three HBD positions:

1. African immigrants to the UK perform better than whites academically because they are a select group, either because they have elite backgrounds or because they tend to be more motivated than the people who stay behind.

2. African immigrants perform better than whites academically, but this academic performance is weakly linked to the heritable component of IQ, especially in modern Britain. Teachers tend to “over-reward” black students who satisfy basic requirements (regular attendance, assignments turned in on time, non-disruptive behavior, etc.). African parents also invest in private tutoring to improve exam results.

3. Most African immigrants perform worse than whites academically. Only certain African groups excel, notably the Igbo of Nigeria. Igbo excellence is due to their specific evolutionary history and cannot be generalized to all sub-Saharan Africans.

Are African immigrants better than the Africans left behind?

Chanda attacks the first argument, saying that the average African immigrant is very average:

I actually know that the average African immigrants to the UK from any nation or tribe are not from the African elite class, economically or intellectually (even if there is a small segment from the super-professional class)

He also points to the example of African American families. The children of middle-class and even upper-class African Americans do worse on IQ tests than the children of lower-class Euro-American families. So even if you select from the black elite, the next generation will still underperform whites.

One could counter that the African American middle class largely works for the government. In Africa, the middle class is more likely to be self-made men and women. Also, a selection effect may exist despite the averageness of most African immigrants to the UK. Even if most are average, it may be that fewer are below-average. Below a certain level of ability, many Africans may not bother to emigrate.

Fuerst (2014) has studied this question and found that black immigrants to the U.S. have a mean IQ that is one third of a standard deviation above the mean IQ of their home countries. So there is a selection effect. But it seems too weak to explain the difference in IQ—more than one standard deviation and possibly two—between African immigrants to the UK and Africans back home, unless one assumes that migration to the UK is a lot more selective than migration to the US.

What does the GCSE actually measure?

We now come to the second explanation. It is assumed in this debate that the GCSE (General Certificate of Secondary Education) is a good proxy for IQ, which in turn is a proxy for the heritable component of intelligence. Is this true? Or does the GCSE largely measure something that is culturally acquired rather than heritable? Perhaps something as simple as showing up for class, doing one’s assignments, or having a private tutor. This point is raised by one commenter:

[...] black Africans in London, even if poor and living in social housing, hire private tutors for their children. White British do not, especially the working class. This much better explains the GCSE results, a very tuition friendly test [...]

Furthermore, many African immigrants may be targeting those exams they can do best on and avoiding those they are less sure about:

[...] one needs to know how many children from each racial group take the exams. For example, the pass rate for Higher Mathematics is very high, not because the exams are easy, but because they are hard, and frighten off most applicants.

Interestingly, Chanda replies to this GCSE skepticism by pointing out that the same “Nigerians” (Igbos) who do well on the GCSE also do well in Nigeria:

For example, the subgroups within the Nigerian group that are the best in Nigeria or even in the US etc are also the best on the GCSEs. Also, the Traveller white (or whatever precise race) groups are placed by the GCSEs exactly where you would expect to find them.


The Igbo factor

This brings us to the third explanation. It’s the one I favor, although the other two probably play a role. African excellence in the UK seems largely driven by a single high-performing people: the Igbo of southeastern Nigeria. Let’s begin with the example of Harold Ekeh, whom Chanda describes in glowing terms:

Harold Ekeh showing off his acceptance letters to all 8 Ivy League Schools. He was born in Nigeria and migrated with his parents at age 8.

Ekeh is an Igbo name, and the Igbo (formerly known as Ibo) have a long history of academic success within Nigeria (Frost, 2015). Chanda himself referred to this success in his first article:

The superior Igbo achievement on GCSEs is not new and has been noted in studies that came before the recent media discovery of African performance. A 2007 report on “case study” model schools in Lambeth also included a rare disclosure of specified Igbo performance (recorded as Ibo in the table below) and it confirms that Igbos have been performing exceptionally well for a long time (5 + A*-C GCSEs); in fact, it is difficult to find a time when they ever performed below British whites. (Chisala, 2015a)

This superior achievement was widely known in Nigeria by the time of independence:

All over Nigeria, Ibos filled urban jobs at every level far out of proportion to their numbers, as laborers and domestic servants, as bureaucrats, corporate managers, and technicians. Two-thirds of the senior jobs in the Nigerian Railway Corporation were held by Ibos. Three-quarters of Nigeria’s diplomats came from the Eastern Region. So did almost half of the 4,500 students graduating from Nigerian universities in 1966. The Ibos became known as the “Jews of Africa,” despised—and envied—for their achievements and acquisitiveness. (Baker, 1980)

The term “Jews of Africa” recurs often in the literature. Henry Kissinger used it back in the 1960s:

The Ibos are the wandering Jews of West Africa — gifted, aggressive, Westernized; at best envied and resented, but mostly despised by the mass of their neighbors in the Federation.(Kissinger, 1969)

To what degree is African success Igbo success? If we go back to Chanda’s first article, we see that high African achievers are overwhelmingly “Nigerians” (Chisala, 2015a). This is evident in a chart that lists mean % difference from the mean English GCSE score in 2010-2011 by ethnicity:

Nigerian: +21.8

Ghanaian: +5.5
Sierra Leone: +1.4
Somali: -23.7
Congolese: -35.3

Clearly, high academic achievement is due to something that is very much present in Nigeria, a little bit in Ghana, and not at all in Somalia and Congo. Could this something be the Igbo? The Igbo make up 18% of Nigeria’s population and form a large diaspora elsewhere in West Africa and farther afield. In fact, they seem to be disproportionately represented in overseas Nigerian communities, making up most of the Nigerian community in Japan and a large portion of China’s Nigerian community (Wikipedia, 2015). Statistics are unfortunately lacking for the UK.

Conclusion

What happens when we remove Igbo students from the GCSE results? How well do the other Africans do? To some degree, Chanda answered that question in his first article. African excellence seems to be overwhelmingly Igbo excellence.

So why doesn’t he speak of Igbo excellence? Probably because he assumes that all sub-Saharan Africans are fundamentally the same. Or maybe he assumes that all humans are fundamentally the same. Both assumptions are wrong, and neither can be construed as an “HBD position.”

We are all genetically different, even within our own families. So why the surprise that different African peoples are … different? The Igbo have for a long time specialized in a trading lifestyle that favors a certain mental toolkit: future time orientation; numeracy, and abstract reasoning. This is gene-culture coevolution. When circumstances push people to excel in a certain way, there will be selection for people who can naturally excel in that way, without the prodding of circumstances. And it doesn’t take eons of time for such evolution to work.

Will we hear more about the Igbo in this debate? Probably not. There is a strong desire, especially in the United Kingdom, to show that blacks are converging toward white norms of behavior, including academic performance. There is indeed some convergence, but almost all of it can be traced to the growing numbers of high-performing “Nigerians” (Igbos) and the growing numbers of biracial children (the census now has a mixed-race category, but most biracial people still self-identify as “black”). In the UK, 55% of Black Caribbean men and 40% of Black Caribbean women have a partner from another ethnic background. It’s very likely that half of all “black” children in the UK are at least half-white by ancestry (Platt, 2009, p. 7).

Nor is it likely that we’ll hear more about the Igbo from Chanda. As he sees it, the debate should be over. The academic excellence of Igbo students proves that the black/white IQ gap in the U.S. cannot have a genetic basis:

[It is not] a function of global racial evolution (Sub-Saharan African genes versus European genes), as most hereditarians believe, especially those who identify with the Human Biodiversity or HBD intellectual movement (generally known as “scientific racism” in academic circles, but we are avoiding such unkind terms).

Thank you, Chanda, for avoiding unkind terms. Well, I know a bit about HBD. The term was coined by Steve Sailer in the late 1990s for an email discussion group that included myself and various academics who may or may not want their names disclosed. It’s hard to generalize but we were all influenced by findings that genetic evolution didn’t slow down as cultural evolution speeded up in our species. In fact, the two seemed to feed into each other. This is why genetic evolution accelerated over 100-fold about 10,000 years ago when humans began to abandon hunting and gathering for farming, which in turn led to ever more diverse societies. Our ancestors thus adapted much more to their cultural environments than to their natural environments. These findings were already circulating within our discussion group before being written up in a paper by Hawks et al. (2007) and later in a book by Greg Cochran and Henry Harpending (2009).

Yes, previously it was thought that genetic evolution slowed to a crawl with the advent of culture. Therefore, groups like the Igbo couldn’t possibly differ genetically from other sub-Saharan Africans, at least not for anything culture-related. But that kind of thinking wasn’t HBD or even racialist. It was simply the old anthropological narrative, and it’s still accepted by many anthropologists, most of whom aren’t “scientific racists.”

Oh sorry, I forgot we promised to avoid that term.

Note

(1) Of course, if the cultural pressure is maintained long enough, there may be selection for individuals who naturally produce the new phenotype—with no prodding and pushing. Let’s suppose that foot binding had never been outlawed in China. Through chance mutations, some Chinese women might be born with tiny feet, and their descendants would become more and more numerous because of their better life prospects. So what began as a new phenotype could end up becoming a new genotype. Culture pushes the limits of phenotypic plasticity, and then favors genotypes that don’t have to be pushed. That’s gene-culture coevolution.

In a mixed group, women become quieter, less assertive, and more compliant. This deference is shown only to men and not to other women in the group. A related phenomenon is the sex gap in self-esteem: women tend to feel less self-esteem in all social settings. The gap begins at puberty and is greatest in the 15-18 age range (Hopcroft, 2009).

Do women learn this behavior? Why, then, do they learn it just as easily in Western societies where constraints on female behavior are much weaker and typically stigmatized?

In U.S. society most of the formal institutional constraints on women have been removed, and ideologies of the inferiority of women are publicly frowned on. Sexual jealousy is also publicly disapproved, however much private expectation there may be of the phenomenon. Resources inequalities between men and women have also been reduced, although not eradicated. Certainly, male violence against women is still a reality and may play a role promoting deference behaviors in college-aged women. However, it seems unlikely that fear of physical violence is enough to explain why young women typically defer to men when involved in non-sex typed tasks in experimental settings. (Hopcroft, 2009)

Moreover, why would this behavior be learned mainly between 15 and 18 years of age?

[...] by many measures, girls at this age in the United States are doing objectively better than boys — they get better grades, have fewer behavioral and disciplinary problems, and are more likely to go to college than boys (Fisher 1999: 82). Qualitative studies also show the decline in female confidence and certainty at adolescence (Brown and Gilligan 1992). Brown and Gilligan’s (1992) study was done in an elite private girls’ school among girls who were likely to have every opportunity in life. Why would their self confidence be eroded at puberty? Certainly, there are few differences in resources between teenage boys and girls. Brown and Gilligan (1992) argue that our sexist culture strikes at girls during puberty, stripping girls of their self esteem. It seems odd that our patriarchal culture should wait until that precise moment to ensnare girls. (Hopcroft, 2009)

Female self-esteem seems to be hormonally influenced. It declines at puberty, reaches its lowest levels in late adolescence, gradually increases during adulthood, and peaks after menopause.

[...] evidence from many cultures [shows that] post-menopausal women often enjoy a status equal to that of men: they become in effect “honorary men.” [...] Even in the most gender restrictive societies they are freed from menstrual taboos and purdah, often begin to inherit property and acquire wealth, and in general have increased freedom, status, power and influence in society. A recent experimental study of influence in small groups showed that older women (50 and older) do not defer to older men, and that older men do not display lack of deference to older women. (Hopcroft, 2009)

Female deference varies not only over a woman’s lifetime but also from one woman to the next, i.e., some women are more predisposed than others. This variability may exist for one or more reasons:

- Not enough time has elapsed for selection to remove contrary predispositions (non-deference) from the gene pool.

- The selection pressure is relatively weak: contrary predispositions appear through mutation as fast as they are removed through selection.

- The strength or weakness of selection may vary among human populations. Gene flow may reintroduce contrary predispositions from populations where the selection pressure against them is relatively weak.

- There may be frequency-dependent selection. Non-deferring women may be better liked when less common.

Sexual selection?

For all these reasons, evolutionary psychologist Rosemary Hopcroft (2009) argues that female deference is an innate predisposition and not a learned behavior. It has become so widespread because deferential women have been better at survival and reproduction via sexual selection. When women compete on the mate market, success goes to the more deferential ones.

One might point out that deferential behavior would be advantageous not only at the time of mating but also later—during pregnancy and infant care. So, strictly speaking, the selection pressure wouldn’t be just sexual selection.

But Hopcroft’s argument is vulnerable to a more serious objection: sexual selection of females is the exception and not the rule in most animal species, especially mammals. The males are the ones that have to compete for mates. This reflects differing contributions to procreation, the female being saddled with the tasks of pregnancy, nursing, and early infant care. Meanwhile, the male is usually free to go back on the mate market, with the result that mateable males outnumber mateable females at any one time.

Hopcroft knows this but argues that the human species is a special case because “human fathers often invest heavily in their children.” But often they don’t. What about societies where men do very little to raise their offspring? This point doesn’t disprove Hopcroft’s argument. In fact, it may provide a way to prove it, i.e., female deference should be stronger where paternal investment is higher.

If we look at hunter-gatherers, paternal investment tends to follow a north-south cline. It’s low in the tropical zone where women gather food year-round and can thus provide for themselves and their children with little male assistance. It’s higher farther away from the equator, where winter limits food gathering and makes women dependent on food that men provide through hunting. Paternal investment is highest in the Arctic: almost all food is provided by men and women specialize in tasks unrelated to food procurement (garment making, shelter building, meat processing).

This north-south cline was maintained and in some cases accentuated when hunting and gathering gave way to farming. In the tropical zone, farming developed out of female food gathering and thus became women’s work, as is still the case in sub-Saharan Africa and Papua New Guinea. This sexual division of labor also explains why tropical farmers preferred to domesticate plants for food production. Only one animal species, the guinea fowl, has been domesticated in sub-Saharan Africa, and it was apparently domesticated by women. All other forms of livestock have come from elsewhere.

How universal is female deference?

Female deference should therefore vary within our species. In particular, it should correlate with the degree of paternal investment in offspring and, relatedly, the intensity of female-female competition for mates. This doesn’t mean that women are actually more deferential in societies where men are providers. It simply means that they create an impression of deference, while continuing to do much of the real decision-making.

This issue is sidestepped by Hopcroft, who speaks only of ‘women’ and ‘men’—as if all human groups show the same pattern of female deference. She cites many studies to prove her point, but this literature is overwhelmingly based on Euro-American or European participants. There is one study on African Americans, but it was limited to boys and girls 11 to 14 years old (Weisfeld et al., 1982).

In fact, this presumed universality of female deference was already disproven by a study published two years earlier:

Much feminist literature has described the relative silence of girls in classrooms and a concomitant drop in self-esteem for girls in their early teens (Sadker & Sadker, 1994; American Association of University Women, 1992). But other work has noted that Black girls maintain their self-esteem and their classroom “voice” into adolescence despite the fact that they may feel neglected in education (Orenstein, 1994; Taylor et al., 1995). (Morris, 2007)

Over a period of two years, Morris (2007) studied African American girls in grades 7 and 9 of an American middle school referred to as “Mathews.” The students were 46% African American and the teachers two-thirds African American.

He found that African American girls seemed to feel little inhibition in the presence of boys:

Indeed, at Matthews I often observed girls—particularly Black girls—dominating classroom discussion.

[...] I noticed this active participation of girls to a greater extent in English classrooms, particularly when, as in this example, the subject concerned gender issues or relationships. However, the topic in this example also concerned computers and technology, areas more commonly dominated by boys. Furthermore, girls at Matthews, especially Black girls, spoke out to ask and answer questions in science and math classes as well, although to a lesser extent than in English and history classes. This willingness of African American girls to compete and stand up to others also emerged in their non-academic interactions with boys.

[...] Black girls at Matthews often challenged physical contact initiated by boys by hitting and chasing them back. They did not yield to and accept this behavior from boys, nor did they tend to seek adult authority to protect themselves and punish the boys.

[...] Thus, most African American girls in my observations did not hesitate to speak up in classrooms, and stand up to boys physically. Few Black girls I observed created disruptions in classrooms, but most consistently competed with boys and other girls to gain teachers’ positive attentions.

[..] I observed this outspokenness at Matthews. Black girls there appeared less restrained by the dominant, White middle-class view of femininity as docile and compliant, and less expectant of male protection than White girls in other educational research.

These observations were consistent with those of the teachers, who generally described African American girls as being confrontational, loud, and unladylike:

Teachers, particularly women, often scolded Black girls for supposedly subverting their authority in the classroom.

[...] By far the most common description and criticism of African American girls by all teachers at Matthews was that they were too “loud.”

[...] For many adults at Matthews, the presumed loud and confrontational behavior of African American girls was viewed as a defect that compromised their very femininity. This emerged most clearly in educators castigating Black girls to behave like “ladies.”

Morris attributed this behavioral pattern to America’s history of slavery and race relations. It would be useful to examine comparable data from sub-Saharan Africa. Do African women show less deference to men in mixed-gender settings?

According to a study of Akan society in Ghana, wives traditionally deferred to their husbands, but such deference was less common than in European society because social interactions were less frequent between husband and wife, being limited to certain areas of family life:

Traditional norms stipulated, for example, that the wife should not eat with the husband; that she alone must carry the foodstuffs from the farm; take water for the husband to the bathroom; sweep the compound; do the cooking; clean her husband’s penis after sexual intercourse; and show deference to him in speech and action. (van der Geest, 1976)

Husbands and wives seldom made decisions jointly:

Joint decision-making is believed to be a departure from the past when decisions were made in a much more autocratic way by the husband alone or when spouses decided over their own matters separately (van der Geest, 1976).

A very different picture existed in mixed-gender settings outside family life. In the community, African women of all ages showed little deference to men, the situation being similar to that of older women in European societies.

Despite these outward rules, however, women held considerable power and commanded wide respect. They played a role in traditional politics and religion and were nearly always economically independent of their husbands. Moreover, women enjoyed a high degree of freedom to enter and to terminate marital unions, and in the matrilineal society of the Akan they were the focal points of descent lines. (van der Geest, 1976)

It is unclear to what degree modernization has changed these social dynamics. Van der Geest (1976) found much interest among younger Akan in the European model of family life, i.e., husband and wife eating and socializing together, and making decisions together. His own study, however, failed to find a significant difference between older and younger Akan in this respect. He concluded that the elite were moving toward European models of behavior, but not the majority of the population:

There are indications that—contrary to the situation in elite circles—marriage in lower socioeconomic groups remains an institution of secondary importance. Spouses have relatively low expectations of their marriage partners and of marriage in general. Men are often reluctant or unable to provide sufficient financial support for their families, and not infrequently women bear the burden of parenthood alone. [...] Wives remain more attached to their families of origin than to their partners, and in almost half of all cases husband and wife do not even constitute a residential unit. The relatively low status of marriage in Kwahu is perhaps best reflected in the high incidence of divorce and extramarital sex. (van der Geest, 1976)

This is consistent with findings from other studies. The pair bond is relatively weak in sub-Saharan Africa. Husband and wife tend to feel greater attachment to their respective kin. The husband is more certain that his sister’s offspring are his blood relatives, whereas the wife sees her mother, sisters, and other female relatives as more reliable sources of child care.

Poewe found in her fieldwork that the marriage institution was highly flexible and discouraged strong, intense, or lasting solidarity between husband and wife. The male in these matrilineal societies did not produce for his progeny or for himself, but usually for a matrician with whom he might or might not reside. His role, as husband, was to sexually satisfy and impregnate his wife and to take care of her during her pregnancies, but under no circumstances should a man be the object of “exclusive emotional investment or focus of attention. Instead, women are socialized to invest their emotions and material wealth in their respective matrilineages.”(Saidi, 2010, p. 16).

For this reason, European outsiders see parental neglect of children where Africans see no neglect at all—simply another system of child care. As Africans move to other parts of the world, they tend to recreate the African marriage system in their host countries by using local people and institutions as “surrogate kin.” This is the case in England, where young African couples often place their children in foster homes:

The foster parents interpret the infrequent visiting of their wards’ “real” parents as signs of parental neglect and become strongly attached to the foster children. This sometimes results in legal suits for transfer of custody to the foster parents (Ellis 1977). Meanwhile, the African parents make no comparable assumption that the delegation of care means they have surrendered formal rights in children. They consider that by having made safe and reliable arrangements for the care of children and by regular payment of fees, they are dispatching their immediate responsibility. (Draper, 1989, p.164)

In recent years, there has been much talk of an “adoption crisis” in Africa, where millions of children are not being raised by both parents and thus purportedly need to be placed in Western homes. Yet this situation is far from new. In fact, it’s unavoidable in a culture where women cannot count on male assistance and have to make other arrangements:

In most African communities, the concept of “adoption” does not exist in the western sense. Children are fostered, a prevalent, culturally sanctioned procedure whereby natal parents allow their children to be reared by adults other than the biological parent [35] [36]. Child fostering is a reciprocal arrangement and contributes to mutually recognised benefits for both natal and fostering families [37]. In Tanzania, less than one quarter of children being fostered by relatives other than their biological parent were orphans. (Foster and Williamson, 2000).

Conclusion

Evolutionary psychologists believe that all human populations share the same genetic influences on behavior. They defend this belief by pointing to the complexity of behavior and the presumably long time it would take for corresponding genetic influences to evolve coherently from scratch. But why do they have to evolve from scratch? Evolution usually proceeds through minor modifications to what already exists. This is no less true for genetic determinants of behavior. For instance, an innate mental algorithm may be partially or completely deactivated. Or its range of targets may be broadened. Or it may deactivate more slowly with increasing age.

To the extent that human groups differ genetically in mental makeup, the differences are not due to some groups having completely new mental algorithms. Instead, the differences are due to the same algorithms being modified in various ways, often subtly so. For example, learning is primarily an infant behavior that becomes more difficult with increasing age. People may differ in learning capacity not because their learning algorithms differ but because these algorithms remain fully active for a longer time in some people than in others.

Another example may be female deference. In early modern humans, women tended to feel deferential in the presence of men, but this tendency was weak because a woman’s interactions with her husband were infrequent and less important for her survival and the survival of her children. This is still the case in human groups that never left the tropical zone.

As humans spread beyond the tropics, this behavioral tendency became more easily triggered, particularly during the ages of 15 to 18 when young women entered the mate market. This evolutionary change came about because women in non-tropical environments were more dependent on men for food, particularly in winter. Women were, so to speak, in a weaker bargaining position than men, first of all on the mate market and later during pregnancy and infant care.
