Wishing you a merry ... something


 
Yale was founded by English Congregationalist ministers. Today, only 22% of its student body has a Christian European background of any sort.

 

Last year, around this time, friends and acquaintances offered me all sorts of religiously neutral salutations: Seasons Greetings! Happy Holidays! Joyeuses fêtes! Meilleurs vœux! Only two people wished me Merry Christmas.

One was Muslim, the other was Jewish.

They meant well. After all, isn't that the culturally correct greeting? In theory, yes. In practice, most Christians feel uncomfortable affirming their identity. And this self-abnegation gets worse the closer you are to the cultural core of Anglo-America. Immigrants of Christian background enjoy being wished Merry Christmas. Black people likewise. Catholics seem to split half and half, depending on how traditional or nominal they are.

But the WASPs. Oh, the WASPs! With them, those two words are a faux pas. The response is usually polite but firm: "And a very happy holiday season to you!"

Things weren’t always that way. The situation calls to mind a Star Trek episode where Capt. Kirk persuades an alien robot to destroy itself. "That which excludes is evil. If you affirm your identity, you are excluding those who don't share your identity. You are therefore evil."

I could question this logic. What about other cultural groups? Why single out just one? But I’ve heard the answer already. WASPs and their culture dominate North America. The path to power, or simply a better life, runs through their institutions. Minorities can affirm their own identities without restricting the life choices of others, but the same does not hold true for WASPs. Their identity affects everyone and must belong to everyone.

I’m still not convinced. Yes, WASPs did create the institutions of Anglo-America, but their influence in them is now nominal at best. The U.S. Supreme Court used to be a very WASPy place. Now, there's not a single White Protestant on it. That's a huge underrepresentation for a group that is still close to 40% of the population. We see the same thing at the Ivy League universities, which originally trained Protestant clergy for the English colonists. Today, how many of their students have any kind of Christian European background? The proportions are estimated to be 20% at Harvard, 22% at Yale, and 15% at Columbia (Unz, 2012).

Sometimes reality is not what is commonly believed.  WASPs are not at all privileged. In fact, they have been largely pushed aside in a country that was once theirs.

Whenever this ethnic displacement comes up for discussion (it usually doesn't), it gets put down to meritocracy. In the past, WASPs were the best people for the job of running the country. Now it's a mix of Jews, Asians, and other high-performing groups. A cynic might ask whether merit is the only factor ... and whether the U.S. is better run today than it was a half-century ago. Indeed, the latest Supreme Court appointee had little experience as a solicitor general and a scanty record of academic scholarship.

Merit isn't the whole story. There is also networking. In most parts of the world, an individual gets ahead in life by forming bonds of reciprocal assistance with family and kinfolk. "You scratch my back, I'll scratch yours." That's how most of the world works.

But not all of the world. Northwest Europeans have diverged the most from this pattern, at least since the 12th century (Macfarlane, 1978a - 2012). Their kinship ties have been weaker and their sense of individualism correspondingly stronger. As a result, their cultural evolution has to a large degree been emancipated from the restraints of kinship, and this emancipation has facilitated other ways of organizing social relations: the nation-state, ideology, the market economy ... not to mention the strange idea of personal advancement through personal merit alone. This model of society has succeeded economically, militarily, and geopolitically, but it's vulnerable to people who don't play by the rules, since the threat of kin retaliation is insufficient to keep them in line. Societal survival is possible only to the extent that rule-breakers are ostracized and immigration restricted from cultures that play by other rules. 

This brings us to the dark side of traditional WASP culture: the busybodiness, the judgmentalism, the distrust of foreigners no matter how nice or refined they may seem. That mentality still exists, but it has been turned against itself. The people to be excluded are now those who exclude. The cultural programming for survival has been turned into a self-destruct mechanism ... as in that Star Trek episode.

Even if we could somehow abort this self-destruct sequence, it's hard to see how WASPs can survive on the current playing field. WASPs believe in getting ahead through rugged individualism. Most of the other groups believe in using family and ethnic connections. Guess who wins.

Anyway, I wish all of you a merry end of 2014! Far be it for me to exclude anyone from the merriment.

We are not equally empathic


 
The Child at Your Door (c. 1917-1919). We're not equally empathic toward strangers. This largely heritable trait varies continuously from psychopathy to extraordinary altruism (source: Wikicommons)

 

In a previous post, I discussed why the capacity for affective empathy varies not only between individuals but also between populations. First, its heritability is high: 68% (Chakrabarti and Baron-Cohen, 2013). So natural selection has had something to grab hold of. Second, its usefulness varies from one culture to another. It matters less where kinship matters more, i.e., where people interact mainly with close kin and where non-kin are likely to be enemies. The threat of retaliation from kin is sufficient to ensure correct behavior.

Affective empathy matters more where kinship matters less. This is a situation that Northwest Europeans have long known. Historian Alan Macfarlane argues that kinship has been weaker among the English—and individualism correspondingly stronger—since at least the 12th century and perhaps since Anglo-Saxon times (Macfarlane, 2012; Macfarlane, 1992, pp. 173-174). A weaker sense of kinship seems to underlie the Western European Marriage Pattern (WEMP), as seen by its defining characteristics: late age of marriage for both sexes; high rate of celibacy; strong tendency of children to form new households; and high circulation of non-kin among families. The WEMP has prevailed since at least the 12th century west of the Hajnal Line, a line running approximately from Trieste to St. Petersburg (Hallam, 1985; Seccombe, 1992, p. 94).

Can natural selection specifically target affective empathy?

So if affective empathy helps people to survive and reproduce, there will be more and more of it in succeeding generations. If not, there will be less and less.

But what exactly is being passed on or not passed on? A specific capacity? Or something more general, like pro-social behavior? If it's too general, natural selection could not easily make some populations more altruistic than others. There would be too many nasty side-effects.

Although pro-social behavior superficially looks like affective empathy, the underlying mental processes are different. Pro-social behavior is a willingness to help others through low-cost assistance: advice, conversation, a helping hand, etc. The logic is simple: give some help now and perhaps you'll receive a lot later from the grateful beneficiary. By the same logic, you may stop helping someone who seldom reciprocates.

Affective empathy is less conscious. It seems to have developed out of cognitive empathy: the ability to simulate what is going on in other people's minds, but not necessarily for the purpose of helping them. Con artists have plenty of cognitive empathy. Empathy is affective when you not only simulate how other people feel but also experience their feelings (Chakrabarti and Baron-Cohen,2013). Their wellbeing comes to matter as much as your own. 

Empathy of either sort relies on unconscious mimicry: "empathic individuals exhibit nonconscious mimicry of the postures, mannerisms, and facial expressions of others (the chameleon effect) to a greater extent than nonempathic individuals" (Carr et al., 2003). The ability to mimic is key to the empathic process of relaying information from one brain area to another via "mirror neurons":

- The superior temporal cortex codes an early visual description of another person's action and sends this information to posterior parietal mirror neurons.

- The posterior parietal cortex codes the precise kinesthetic aspect of the action and sends the information to inferior frontal mirror neurons.

- The inferior frontal cortex codes the purpose of the action.

- Parietal and frontal mirror areas send copies of motor plans back to the superior temporal cortex in order to match the visual description of the person's action to the predicted sensory consequences for that person.

- The mental simulation is complete when the visual description has been matched to the predicted sensory consequences (Carr et al., 2003).

By simulating the sensory consequences of what someone does or intends to do, we gain an understanding of that person that goes beyond what our senses immediately tell us. 

[...] we understand the feelings of others via a mechanism of action representation shaping emotional content, such that we ground our empathic resonance in the experience of our acting body and the emotions associated with specific movements. As Lipps noted, ''When I observe a circus performer on a hanging wire, I feel I am inside him.'' To empathize, we need to invoke the representation of the actions associated with the emotions we are witnessing. (Carr et al., 2003)

Affective empathy exists when this mental representation is fed into our own emotional state. We feel what the other person feels and we act appropriately. This is much more than pro-social behavior.

From psychopaths to extraordinary altruists

The capacity for affective empathy varies from one person to the next. It is least developed in psychopaths:

Psychopathy is a heritable developmental disorder characterized by an uncaring nature, antisocial and aggressive behavior, and deficient prosocial emotions such as empathy, guilt, and remorse. Psychopaths exhibit consistent patterns of neuroanatomical and functional impairments, such as reductions in the volume of the amygdala and in the responsiveness of this structure to fear-relevant stimuli. These deficits may underlie the perceptual insensitivity to fearful facial expressions and other fear-relevant stimuli observed in this population. (Marsh et al., 2014)

Mainstream opinion accepts that psychopaths are heritably different because they are "sick." Heritable differences are thus thought to be unusual and even pathological. "Normal" individuals may vary in their capacity for affective empathy, but surely that sort of variability is due to their environment, isn't it?

No it isn't. That variability, too, is largely genetic. Affective empathy varies over a largely heritable continuum, and an arbitrary line is all that separates psychopaths from "normal" individuals. There may be many psychopaths or there may be few; it depends on where you set the cut-off point.

At the other end of this continuum is another interesting group: extraordinary altruists. A research team has recently looked at the brains of such people, specifically individuals who had donated one of their kidneys to a stranger:

Given emerging consensus that psychopathy is a continuously distributed variable within the general population and that psychopaths represent one extreme end of a caring continuum, we hypothesized that extraordinary altruism may represent the opposite end of this continuum and be supported by neural and cognitive mechanisms that represent the inverse of psychopathy; in particular, increased amygdala volume and responsiveness to fearful facial expressions. (Marsh etal., 2014)

In extraordinary altruists, the right amygdala is larger and responds more to fearful facial expressions. This is the inverse of what we see in psychopaths, who have smaller amygdala and are less responsive to fearful facial expressions.

Affective empathy is thus a specific mental trait, like psychopathy. It is not a form of pro-social behavior any more than psychopathy is a form of antisociality:

[...] it is important to distinguish between antisociality that results from psychopathy, which is specifically associated with reduced empathy and concern for others, as well as with reduced sensitivity to others' fear and distress, and antisociality that results from any of a variety of other factors, such as impulsivity or trauma exposure, that are not closely related to empathy. (Marshet al., 2014)

Marsh et al. (2014) cite a number of studies to show the relative independence of these two behavioral axes: prosociality / antisociality and affective empathy / psychopathy.

Conclusion

Affective empathy is specific and largely heritable. People differ continuously in their innate capacity for affective empathy, and it is only by setting an arbitrary cut-off point that we classify some as "psychopaths" and others as "normal," including extraordinary altruists who may be a small minority.

Affective empathy is an intricate adaptation that must have evolved for some reason. Initially, it may have served to facilitate the relationship between a mother and her children, this being perhaps why it is stronger in women than in men (Baron-Cohen and Wheelwright, 2004). In some cultures, natural selection may have increased this capacity in both sexes and extended it to a wider range of social interactions. This scenario would especially apply to Northwest Europeans, who have long had relatively weak kinship. They have consequently relied more on internal means of behavior control, like affective empathy (Frost, 2014).

Dear Fred


In a recent post, Fred Reed asks:


Why should I not indulge my hobby of torturing to death the severely genetically retarded? This would seem beneficial. We certainly don't want them to reproduce, they use resources better invested in healthy children, and it makes no evolutionary difference whether they die quietly or screaming.


The short answer is that any killing, for whatever reason, increases the likelihood of killing for other reasons. One exception is self-defence, but that's not done for pleasure. Another exception is capital punishment, but that, too, is not done for pleasure. More to the point, no single citizen can carry out an execution. It requires a lengthy judicial process. The same reasoning applies to the final exception of war. No single citizen can declare war.

It's not for nothing that killing is so taboo, especially recreational killing. Several things have contributed to the success of Western societies, but a leading one is the relatively peaceful nature of social relations. When people can go about their business without fearing for their lives, much becomes possible that otherwise would not be. This taboo is so crucial that we even extend it to nonhumans. Cats and dogs have no inherent right to life, yet it is a serious offence to torture them to death.
 

That's society. What about biology?

At this point, Fred may speak up: "But those are social reasons against killing of any sort. What are the biological reasons?"

The immediate biological reason is empathy. If I try to hurt someone, I feel the pain I inflict. Truth be told, the only life forms I enjoy killing are flies and mosquitoes. If a moth flies into our home, I'll go to some length to capture it and set it free outside, and I know others who do similar things. Just think of all the car drivers who come to a screeching halt to avoid running over some poor animal.

It's empathy that makes me and others act that way. And I cannot easily turn it off. It shuts down only when feelings of contempt enter my mind, as with those contemptible flies and mosquitoes.

Empathy is hardwired. It's 68% heritable in the case of affective empathy, i.e., the capacity to respond with the appropriate emotion to another person's mental state (Chakrabarti and Baron-Cohen, 2013). To date, studies have focused on disorders caused by too much empathy or too little. Psychopaths may have intact cognitive empathy, but impaired affective empathy. They keenly understand how others feel without actually experiencing those feelings. The reverse impairment may affect autists. As for depressives, they may suffer from being too sensitive to the distress of others and to guilt over not helping them enough. 

These disorders exist at the tail ends of a normal distribution. By focusing on these extremes, we forget the variability among healthy individuals. We all vary in our capacity for empathy, just as we do for almost any mental capacity.
 

How can evolution explain empathy?

Why do we feel empathy? How could natural selection favor such selflessness? This is of course the point that Fred is trying to make. Empathy keeps us from doing things that supposedly make evolutionary sense. Therefore, it could not have evolved. It must have been given to us by a Great Designer.

But why did this Great Designer give more of it to some people than to others? We're talking about a heritable trait. It's not as if everyone starts off the same way, with some later falling behind through their own wrongdoing.

And how has the Great Designer preserved this selfless behavior? Unless something is done, empathic people will eventually be overwhelmed by a tidal wave of cheaters, free riders, and people shouting "Gimme! Gimme! Gimme!" This is as much a mystery for creationists as it is for evolutionists. It's one thing to explain how altruism came to be. It's another to explain how it manages to survive in this cynical world.

These questions passed through my mind when I was going through my late mother's effects. I discovered she had for years been donating money for various projects in the Third World, at a time when she was a widow with no pension. Meanwhile, as a teenager, I had to take on all kinds of odd jobs to help us make ends meet. Looking over those donor receipts I shook my head and felt some resentment. How do good Christians like her manage to survive?

Yet she did, like others before her. For one thing, she was suspicious of strangers, and this suspicion extended to some ethnic groups more than to others. She was prejudiced and "postjudiced." If someone acted dishonestly with her once too often, she would have no more to do with him or her. Such people were "contemptible."

Today, that sort of behavior might seem un-Christian. But her Christianity was of an older, judgmental sort, being inspired more by the punitive Old Testament than by the forgiving New Testament. She would judge people, and her judgment could be harsh, very harsh.
 

Over space and time

Just as the capacity for empathy varies from one individual to another, it also varies statistically from one human population to another, being strongest in the "guilt cultures" of Northwest Europe. Guilt is the twin sister of empathy. Both flow from a simulation of how another person thinks or feels (an imaginary witness to a wrongdoing, a person in distress) and both ensure correct behavior by inducing the appropriate feelings (anguish, pity).

Why are guilt and empathy so strong in Northwest Europeans? Other societies ensure good behavior by relying on close kin to step in and enforce social rules. This policing mechanism has been less effective west of the Hajnal line (which runs roughly from Trieste to St. Petersburg) because kinship ties have been correspondingly weaker. There has thus been stronger selection for internal means of behavior control, like guilt and empathy.

This zone of relatively weak kinship is associated with unusual demographic tendencies, called the Western European Marriage Pattern:

- relatively late marriage for men and women

- many people who never marry

- neolocality (children leave the family household to form new households)

- high circulation of non-kin among different households (Hajnal, 1964; ICA, 2013)


The Western European Marriage Pattern was thought to have arisen after the Black Death of the 14th century. There is now good evidence for its existence before the Black Death and fragmentary evidence going back to 9th century France and earlier (Hallam, 1985; Seccombe, 1992, p. 94). Historian Alan Macfarlane likewise sees an English tendency toward weaker kinship ties before the 13th century and even during Anglo-Saxon times (Macfarlane, 2012; Macfarlane, 1992, pp. 173-174). I have argued that this tendency probably goes still farther back (Frost, 2013a; Frost, 2013b).
 

Whatever the ultimate cause, Northwest Europeans seem to have been pre-adapted for later shifts away from kinship and toward alternate means of organizing social relations (i.e., ideology, codified law, commerce). This tendency has taken various forms: the intense guilt-driven Christianity of the Anglo-Saxon penitential tradition and, later, Protestantism; the medieval alliance between Church and State to pacify social relations; and the post-medieval rise of the market economy. This cultural evolution has been described by the historical economist Gregory Clark for the English population between the 12th and 19th centuries. As England became a settled society, success went to those who could resolve disputes amiably and profit from thinking ahead—in short, those who had middle-class values of thrift, foresight, self-control, nonviolence, and sobriety. This English middle class, initially tiny, grew in numbers until its lineages accounted for most of its country’s gene pool (Clark, 2007; Clark, 2009a; Clark, 2009b).
 

But what does that have to do with evolution???
 
At this point, Fred may again speak up, with more than a touch of exasperation: "You're ducking my question! You're talking about culture, society, and religion! What does that have to do with evolution???"

Everything, Fred. Everything. Unlike other animals, humans have to adapt not only to their physical environment but also to their cultural environment. In short, we've become participants in our own evolution. We have domesticated ourselves.

Let me return to your initial question. What's to stop you from torturing to death the severely retarded? First, your sense of empathy should. If it doesn't, you're the one with a severe mental defect. I wouldn't want you as a fellow citizen, let alone as a neighbor. The law of the jungle may give you the right to torture defenceless people to death, but it also gives me the right to organize a lynch mob and hang you from the nearest tree.

How universal is empathy?


 
Bronislaw Malinowski with natives on the Trobriand Islands (1918 - source). Pro-social behavior seems to be a human universal, but is the same true for full empathy?
 

What is empathy? It has at least three components:

- pro-social behavior, i.e., actions of compassion to help others

- cognitive empathy, i.e., capacity to understand another person's mental state

- affective or emotional empathy, i.e., capacity to respond with the appropriate emotion to another person's mental state (Chakrabarti and Baron-Cohen, 2013)

In their review of the literature, Chakrabarti and Baron-Cohen (2013) conclude that all three components are moderately to highly heritable, although the affective component seems to show the highest heritability (68%). This is in line with Davis et al. (1994), who found significant heritability for the affective facets of empathy (empathic concern and personal distress) but not for non-affective perspective taking.

All three components can vary from one individual to another, although studies to date have focused on pathological variation:

For example, it is suggested that people with psychopathic personality disorder may have intact cognitive empathy (hence being able to deceive others), but impaired affective empathy (hence being able to hurt others), whilst people with autism may show the opposite profile (hence finding the social world confusing because of their deficit in cognitive empathy, but not being over-represented among criminal offenders, having no wish to hurt others, suggesting their affective empathy may be intact) (Chakrabarti and Baron-Cohen, 2013)


People with depression may suffer from too much empathy, i.e., being too sensitive to the needs or distress of others (O'Connor et al., 2007). In short, these disorders seem to be the tail ends of a normal distribution. By focusing on these extremes, we forget that most of the genetic variability in empathy occurs among healthy individuals (Gillberg, 2007). 

Using research findings on autism and Asperger syndrome, Chakrabarti and Baron-Cohen (2013) have identified nine candidate genes that seem to promote empathy. They fall into three functional categories: sex-steroid synthesis and metabolism; neural development and connectivity; and social-emotional responsivity. The first category includes the degree to which a fetus is androgenized or estrogenized before birth, as shown by digit ratio (Frost, 2014).
 

Variation among human populations

If the genes associated with empathy vary among healthy individuals, do they also vary among human populations? This would be expected because populations have differed in their needs for different components of empathy, particularly since hunting and gathering gave way to farming some 10,000 years ago—when genetic change speeded up over a hundred-fold. At that time, humans were no longer adapting to new physical environments. They were adapting to new cultural environments that differed in social structure, in division of labor, in means of subsistence, in norms of conduct, in future time orientation, in degree of sedentary living, and so on. Our ancestors were now reshaping their environments, and these human-made environments were now reshaping them—in other words, gene-culture co-evolution (Hawks et al., 2007).

Humans have been transformed especially by the shift from small bands of hunter-gatherers to larger and more complex groups of farmers and townsfolk. With social relations expanding beyond the circle of close kin, kinship obligations were no longer enough to ensure mutual assistance and stop free riding. There was thus selection for pro-social behavior, i.e., a spontaneous willingness to help not only kin but also non-kin.

Pro-social behavior is attested across a wide range of cultures. It is the subject of a recent book about the nature and limits of empathy in Oceanic cultures. The Banabans of Fiji for instance express the idea of pro-sociality through the term nanoanga, which they normally translate into English by "compassion" or "pity."

[...] compassion is the basis for their capacity to bond socially with others, even compassion to the point of readiness to take strangers into their community. Their empathy therefore relates causally to how they act socially toward others. Here compassion or pity embraces both understanding and fellow feeling: the islanders understand that the stranded mariner is at the end of his strength, which is why they succor him and treat him as one of their own. They understand him because he, like them, is a human being, a person. [...] Thus, for example, when someone passing by a house does not belong to the immediate family of those inside, it is customary to welcome the passer-by by calling out the words mai rin! (Come in!), which carry the implication that food and drink will not be found wanting inside. (Hermann, 2011, p. 31)


This desire to help non-kin is not unconditional. The author notes that prior experiences with an individual in distress can determine whether compassion will be given or withheld. Moreover, Barnabans can "proceed strategically when deciding whether to extend trust to others or to keep thoughts and feelings to themselves" (Hermann, 2011, p. 31). This is not the affective empathy of entering another person's mind to feel his or her pain.
 
When the Barnabans compare themselves with others, and when by their behavior toward the stranger they show that they understand him and feel with him, they do not, however, equate themselves fully and entirely with him. (Hermann, 2011, p. 32)

 
Another contributor to the same book writes similarly about the inhabitants of Vanatinai, in the Trobriand Islands.
 
On the island of Vanatinai, when someone, including an ethnographer, privately asks a trusted confidant, "Why did she/he act like that?" "What was she/he thinking?" the common answer, often uttered in tones of puzzlement and despair, or anxiety and fear, expresses one of the islanders' core epistemological principles: "We cannot know their renuanga." Renuanga is a word that refers to a person's inner experiences, both and inseparably thought and emotion.

 
[...] And their psychic states, their inner thought and feelings, are inherently unknowable. It may never be clear why they were angry or sympathetic, and what caused them to act and influence an event in someone's life [...] (Lepowsky, 2011, p. 44)

 
In short, Oceanic cultures display hospitality but not full empathy, which would be considered undesirable anyway:

The philosophical principle of personal opacity, the interiority of others' thoughts/feelings (renuanga), is closely bound to the islanders' fierce insistence on personal autonomy, both as cultural ideology and as daily social practice (Lepowsky, 2011, p. 47)

 

From pro-sociality to full empathy

Whereas pro-sociality is attested across a wide range of cultures, full cognitive/affective empathy is more localized. The difference is like the one we see between shame and guilt. Most cultures primarily use shame to enforce correct behavior, i.e., if other people see you breaking a rule, you feel ashamed and this feeling is reinforced by social disapproval. In contrast, only a minority of cultures—largely those of Northwest Europe—rely primarily on guilt, which operates even when only you see yourself breaking a rule or merely think about breaking a rule (Benedict, 1946; Creighton, 1990).

Northwest Europeans have thus undergone two parallel changes in behavioral control: 1) a shift from pro-sociality to full cognitive/affective empathy; and 2) a shift from shame to guilt. Indeed, full empathy and guilt may be two sides of the same coin. Both are the consequences of a mental model that is used to simulate how another person thinks or feels (an imaginary witness to a wrongful act, a person in distress) and to ensure correct behavior by inducing the appropriate feelings (anguish, pity).

Finally, full empathy and guilt are most adaptive where kinship ties are relatively weak and where rules of correct behavior require a leveling of the playing field between kin and non-kin. This has long been the case in Northwest Europe. There seems to be a longstanding pattern of weak kinship ties west of a line running from Trieste to St. Petersburg, as shown by several culture traits that are rare or absent elsewhere:

- relatively late marriage for men and women

- many people who never marry

- neolocality (children leave the family household to form new households)

- high circulation of non-kin among different households (typically young people sent out as servants) (Hajnal, 1965)

Commonly called the Western European Marriage Pattern, this geographic zone of relatively weak kinship was thought to have arisen after the Black Death of the 14th century. There is now good evidence for its existence before the Black Death and fragmentary evidence going back to 9th century France and even earlier (Hallam, 1985; Seccombe, 1992, p. 94). Historian Alan Macfarlane likewise sees an English tendency toward weaker kinship ties before the 13th century and even during Anglo-Saxon times (Macfarlane, 2012; Macfarlane, 1992, pp. 173-174).

This weak kinship zone may have arisen in prehistory along the coasts of the North Sea and the Baltic, which were once home to a unique Mesolithic culture (Price, 1991). An abundance of marine resources enabled hunter-fisher-gatherers to achieve high population densities by congregating each year in large coastal agglomerations for fishing, sealing, and shellfish collecting. Population densities were comparable in fact to those of farming societies, but unlike the latter there was much "churning" because these agglomerations formed and reformed on a yearly basis. Kinship obligations would have been insufficient to resolve disputes peaceably, to manage shared resources, and to ensure respect for social rules. Initially, peer pressure was probably used to get people to see things from the other person's perspective. Over time, however, the pressure of natural selection would have favored individuals who more readily felt this equivalence of perspectives, the result being a progressive hardwiring of compassion and shame and their gradual transformation into empathy and guilt (Frost, 2013a; Frost, 2013b).

Empathy and guilt are brutally effective ways to enforce social rules. If one disobeys these internal overseers, the result is self-punishment that passes through three stages: anguish, depression and, ultimately, suicidal ideation.

People suffering from depression are looking at both others and themselves with suspicion, often believing whatever they have was obtained by cheating, and that it is more than they deserve. Depressives, burdened by moralistic standards, are harsh evaluators of both themselves and others. The self-punishment meted out by depressives is a common if disturbing symptom; while thinking 'I deserve this', they may engage in altruistic punishment turned upon the self. Just as altruistic punishers experience a neuronally based reward from punishing defectors, despite material costs, depressed patients report a sense of relief upon inflicting self-punishment. Patients who are 'cutters', describe relief from tension after cutting and depressives with suicidal ideation may describe the relief they felt when on the verge of attempting a suicidal action. (O'Connor et al., 2007, p. 67)


This pathology is progressively less common in populations farther south and east, not so much because each stage is less common but rather because depression is much less likely to result from empathic guilt and much less likely to lead to suicide (Stompe et al., 2001). This 3-stage sequence does not seem to be a human universal, at least not to the same extent as in Northwest Europeans, a reality that Frantz Fanon noted when describing clinical depression in Algerians: 

French psychiatrists in Algeria found themselves faced with a difficult problem. When treating a melancholic patient, they were accustomed to being afraid of suicide. The melancholic Algerian kills, however. This disease of the moral conscience that is always accompanied by self-accusation and self-destructive tendencies assumes hetero-destructive forms in the Algerian. The melancholic Algerian does not commit suicide. He kills. (Fanon, 1970, pp. 219-220)

Compliance with moral norms: a partly heritable trait?


 
Election poster from the 1930s for Sweden’s Social Democratic Party (source). Is the welfare state more workable if the population is more predisposed to obey moral norms?
 

Do we differ genetically in our ability, or willingness, to comply with moral norms? Please note: I'm talking about compliance. The norms themselves can vary greatly from one historical period to another and from one society to another.

Apparently some people are more norm-compliant than others. This is the conclusion of a recent twin study from Sweden (Loewen et al., 2013). A total of 2,273 individuals from twin pairs were queried about the acceptability of four dishonest behaviors: claiming sick benefits while healthy (1.4% thought it totally or fairly acceptable), avoiding paying for public transit (2.8%), avoiding paying taxes (9.7%), and accepting bribes on the job (6.4%).

How heritable were the responses to the above questions? The heritabilities were as follows: 

Claiming sick benefits while healthy - 42.5%
Avoiding paying for public transit - 42.3%
Avoiding paying taxes - 26.3%
Accepting bribes on the job - 39.7%

Do these results indicate a specific predisposition to obey moral norms? Or is the genetic influence something more general, like religiosity or risk-taking, both of which are known to be partly heritable? To answer this question, the authors ran correlations with other factors:


Significant correlations were exhibited for age (r=.10, p=.00), sex (r=.12, p=.00), religiosity (r=.06, p=.00), preferences for risk (r=-.09, p=.00) and fairness (r=-.10, p=.00), locus of control (r=-.03, p=.01), and charitable giving (r=.09, p=.00). However, these significant correlations were relatively weak, suggesting that our measure is not merely standing in for these demographic and psychological differences between individuals. There were no significant correlations with behavioral inhibition (r=-.00, p=.81) or volunteering (r=.01, p=.29). (Loewen et al., 2013)


The jury is still out, but it looks like compliance with moral norms has a specific heritable component.
 

Population differences

Does this heritable component vary from one population to another, just as it seems to vary from one individual to another? The authors have little to say, other than the following:


Replication in other countries should occur, as the exact role and extent of genetic and common environment-influence could change in different national and cultural contexts. Such a multi-country approach could thus offer some clues on the generalizability of our findings. (Loewen et al., 2013)


Swedes seem to be better than most people at obeying moral norms. Only 1.4% think it acceptable to claim sick benefits while healthy! Maybe that's why they've been so successful at creating a welfare state. So few of them want to be free riders on the gravy train:


Gunnar and Alva Myrdal were the intellectual parents of the Swedish welfare state. In the 1930s they came to believe that Sweden was the ideal candidate for a cradle-to-grave welfare state. First of all, the Swedish population was small and homogeneous, with high levels of trust in one another and the government. Because Sweden never had a feudal period and the government always allowed some sort of popular representation, the land-owning farmers got used to seeing authorities and the government more as part of their own people and society than as external enemies. Second, the civil service was efficient and free from corruption. Third, a Protestant work-ethic—and strong social pressures from family, friends and neighbors to conform to that ethic—meant that people would work hard, even as taxes rose and social assistance expanded. Finally, that work would be very productive, given Sweden´s well-educated population and strong export sector. (Norberg, 2006)


This is not how most of the world works. While studying in Russia, I noticed that the typical Russian feels a strong sense of moral responsibility toward immediate family and longstanding friends, more so than we in the West. Beyond that charmed circle, however, the general feeling seems to be distrust, wariness, or indifference. There was little of the spontaneous willingness to help strangers that I had taken for granted back home. People had the same sense of right and wrong, but this moral universe was strongly centered on their own families.

In sociology, the term is amoral familialism. Family is everything and society is nothing, or almost nothing. It was coined by American sociologist Edward Banfield:


In 1958, Banfield, with the assistance of his wife, Laura, published The Moral Basis of a Backward Society, in which they explained why a region in southern Italy was poor. The reason, they said, was not government neglect or poor education, but culture. People in this area were reluctant to cooperate outside of their families. This kind of "amoral familialism," as they called it, was the result of a high death rate, a defective system of owning land, and the absence of extended families. By contrast, in an equally forbidding part of southern Utah, the residents were engaged in a variety of associations, each busily involved in improving the life of the community. In southern Italy, people did not cooperate; in southern Utah, they scarcely did anything else. (Banfield, 2003, p. viii)
 

Where did Western societies get this desire to treat family and non-family the same way? To some extent, it seems to be a longstanding trait. English historian Alan Macfarlane sees a tendency toward weaker kinship ties that goes back at least to the 13th century. Children had no automatic rights to the family property. Parents could leave their property to whomever they liked and disinherit their children if they so wished (Macfarlane, 2012).

Indeed, Macfarlane argues that "Weber's de-familization of society" was already well advanced in Anglo-Saxon times (Macfarlane, 1992, pp. 173-174). This picture of relatively weak kinship ties is consistent with the Western European marriage pattern. If we look at European societies west of a line running from Trieste to St. Petersburg, we find that certain cultural traits predominate:

- relatively late marriage for men and women
- many people who never marry
- neolocality (children leave the family household to form new households)
- high circulation of non-kin among different households (typically young people sent out as servants) (Hajnal, 1965; see also hbd* chick)

Again, these characteristics go back at least to the 13th century and perhaps much farther back (Seccombe, 1992, p. 94).

Historians associate this model of society with the rise of the market economy. In other words, reciprocal kinship obligations were replaced with monetized economic obligations, and this process in turn led to a broader-based morality that applied to everyone equally. In reality, the arrow of causation seems to have been the reverse. Certain societies, notably those of northwestern Europe, were pre-adapted to the market economy and thus better able to exploit its possibilities when it began to take off in the late Middle Ages. The expansion of the market economy and, later, that of the welfare state were thus made possible by certain pre-existing cultural and possibly genetic characteristics, i.e., weaker kinship ties and a corresponding extension of morality from the familial level to the societal level.
