Till Eulenspiegel, a classical trickster in European cultures

The trickster type may really be Nature's penetration tester who tests our defences against adversity. 

The type probably emerges in contexts of unequal power (Person A has the shotgun; person B doesn’t). Thus, an abiding fear is the soil out of which tricksterism grows, by the following positive feedback: A successful trick shows up the more powerful persons and shows them in a feckless light, which reduces the fear level of the trickster, which reinforces trick-playing. This is a short-term high that comes at the expense of worse relations with the more powerful persons and thus eventually even greater fear levels for the tricksters, which they try to remedy with still more tricks. An example of an unequal power relationship is between a foreign invader and the defenders. Invasion is such a common event in history that by now, countermeasures will have evolved. Tricksterism is likely to be a tile in the mosaic of any such adaptation. 

Tricksterism also seems to be a form of play. A result from animal ethology is that the play of young animals is a form of learning. The thing learned in playing tricks may be how to manage power inequalities.

A biological precedent for penetration testing?

Evidence for a biological precedent may be the many retroviruses integrated into the human genome. One of these may become active now and then at random and kills the host cell if the anti-viral defences of the latter have become weak due to some somatic mutation. The red team-blue team strategy seems to be too good a trick for nature to miss.

Evolution of the trickster

Modern human populations may have two independent axes of political polarization: oppressor-oppressed and trickster-control valuer. The first may subserve dispersal by generating refugee groups and the second may subserve building. Any built thing must serve in a complex world in which many constraints must be simultaneously observed. Thus, after the initial build, a long period of tweaking must typically follow. The role of the tricksters is to powerfully motivate this tweaking, for example, by cleverly making someone’s shelter fall down, before the complacency of the control-valuer builders leads to disaster. This may have been how engineering was done by an archaic version of Homo sapiens. Tricksterism may have evolved out of a previously evolved capacity for military strategy, which involves essentially putting one over on the enemy. 

Tricksterism today

The tricksters can also make mistakes, causing damage that cannot have a silver lining in any possible world, and moving to correct this is a natural role of the builders. If you are a builder, ask this: “What is the best use of my indignation?” It is to keep to a strict harm-reduction approach. 

Tricksterism can intensify into sadism, in which the protagonist takes pleasure in the victim’s torment and wants to make it last. However, if you make it last, you are giving the victim plenty of time and motivation to figure out solutions, like a patient old instructor giving his pupil his lessons one at a time, as he is ready for them, and this is how the wise victim will construct the situation. Such a victim will end up with information and know-how others will pay for. 

Before the trickster

Our evolutionary forebears may have been champion dispersers for a long time before the ice age forced some of them to become champion builders, initially, of shelters and warm clothing. (Champion environment modifiers may be closer to the mark.) It is an interesting fact that physically, humans exceed all other animals only in long-distance running, which can be read as dispersal ability. Our carelessness with preserving the local environments and our propensity for overpopulation can be read as typical r-selected disperser behavior. The r-selecting niche may have been big game hunting. H. erectus sites indicate consumption of medium and large meat animals. Overhunting would have occurred routinely, due to the slow reproduction rates of large animals and the high hunting efficiency of H. erectus due to tool use, so that dispersal of the hunters to new habitats would likewise have been routine.

#53. Where are All the Space Aliens? [evolution, evolutionary psychology]

EP    EV

Red, theory; black, fact

Canada's remote Algonquin Radio Observatory,

which took over SETI duty between 1988-91.

Astronomical observations and the Fermi paradox

Contemporary exoplanet research keeps turning up extra-solar-system planets that seem to be promising abodes of life of the Earthly variety (never mind the completely weird biochemistries that may exist on other planets). In the habitable exoplanets catalogue (HEC), kept by the Planetary Habitability Laboratory, University of Puerto Rico, Arecibo, the list of planets found orbiting in the conservative habitable zone now has 17 entries, and a 2013 paper by Petigura et al. ("Prevalence of Earth-size planets orbiting Sun-like stars") placed the percentage of stars in our galaxy with potentially habitable planets at 22 ± 8. Accumulating evidence suggests that life is common in our galaxy, yet SETI research—the search for extraterrestrial civilizations that send out radio signals that bear some stamp of intelligence—has drawn a complete blank, as far as I know. And if it did find something, it would make such a sensation in the media that no-one could help knowing. So I ask you: where are all the space aliens? This question is generally attributed to 20th-century physicist Enrico Fermi and has since become known as the Fermi Paradox.

My hypothesis is this:

Life is one thing; intelligent life is quite another. This is a form of the Rare Earth hypothesis, which is one of the avenues that has been explored through the years in the search for a resolution of the Fermi Paradox.

Biospheres may not be permanent 

No doubt there are many, many planets in our part of the galaxy that have some form of primitive life, and many, many more "graveyard planets" that once had life but are now sterile. Mars may well be an example of this kind of planet in our own solar system.

Biochallenge!

I conjecture that if we seem to be alone in this part of the galaxy, based on the negative SETI evidence, it is because we are, and this is because we have evolved to the level of intelligence first in this galactic neighborhood, because evolution on the Earth is egregiously rapid. It has taken us four billion years to get this far, which doesn't sound so fast, but everything is relative. This rapid evolution is plausibly a response to challenges: all the various natural disasters we are subject to here on Earth, examples being bolide (meteor) crashes, continental glaciations, drifting continents, droughts, earthquakes, floods, hurricanes, long climatic warm spells, tornadoes, tsunamis, volcanism, wild weather, wildfires, and winter.

Sept 23, 2018: Tornadoes knock out primary transformer station in my town.

Case in point: a large bolide strike is believed to have triggered the extinction of the dinosaurs, making way for the rise of the mammals, and we ourselves are the descendants of those mammals. The bolide may have killed the dinosaurs indirectly, by touching off a climate shift in our dangerously unstable world. This would explain the temporary presence of dinosaur fossils above the Cretaceous/Tertiary iridium anomaly, which has been a problem for the bolide hypothesis.

Case in point: the rise of modern humans seems to have coincided with the end of the last continental glaciation. The rigorous, cold-climate conditions prevailing then might have selected our ancestors for high ability in building shelters and sewing protective clothing. These skills might have required the rapid evolution of a high ability to process spatial information, which we then leveraged into the building of civilizations upon the return of temperate climatic conditions.

To contrive a planet that is so challenging and difficult, yet has not succeeded in destroying life altogether in four billion years, may require a very rare combination of parameters (e.g., our distance from the sun, the size and composition of the Earth, the presence of the asteroid belt, the presence of the Oort cloud), and this rarity has led to our emerging into intelligence before it happened anywhere else in this part of the galaxy.

These parameters may well have special values at which critical behavior occurs, such as the onset of positive feedbacks leading to heating or cooling. Earth may be simultaneously close to several of these critical points, a rare circumstance, but one that does not require extreme, atypical values of any given variable.

My take on the Rare Earth hypothesis therefore emphasizes what are called "evolutionary pumps" (e.g., glaciations, bolide crashes, etc.) in discussions of this hypothesis, as well as the anthropic principle.

Evolution

I further conjecture that the difficulties of our past have left their mark on us, and we call it "evil." Some will deny that this concept has any construct validity, saying, "It's not a thing," but I think that it is an approximate version of something that does, which I term "dispersalism" in this blog. This is because a basic strategy for surviving disasters is dispersal. 

Our planet's predilection for disaster has deeply ingrained dispersal tendencies into most species here, by the mechanism of natural selection. Humans now get their food from agriculture. However, agriculture requires a settled existence and is therefore in opposition to dispersal, so the plot thickens.

This characteristic of agriculture results in the psychological pressure for dispersal relentlessly building, pressure-cooker fashion, across time, until a destructive explosion occurs (war or revolution), thereby accomplishing the long-delayed dispersal.

#51. Advanced Human Depopulation Model [population, evolutionary psychology]

PO   EP

Red, theory; black, fact

Picture 1: A four-stage model of a human depopulation event. C = cycle; growth = growth phase; depop = depopulation

Picture 1 shows a four-stage model of human depopulation events that is intended to account for more data than heretofore. The same two emotional programs, the anger cycle and the sadness cycle occur in two "generations," with the second generation having greater violence and using modified signals.

• Stage 1: depopulation by emigration; accomplishes dispersal of the human species; coordinated by an exchange of anger signals;
• Stages 2-4: depopulation by mass murder: accomplishes long-term population density confinement within limits;
• Stage 2: coordinated by an asymmetric exchange of contempt and sadness signals; has similarities with cannibalism;
• Stage 3: total war program; coordinated by an exchange of anger signals with mimicry added;
• Stage 4: loss of civilization; triggered by a repudiation of the social contract by trusted elites with grudges: coordinated by increasing paralysis on the part of victims and increasing cynicism on the part of perpetrators. May be too recent an evolutionary development to have an efficient halting signal.

Nevertheless, the modes of worship of Islam are the best place to look for such a signal or other remedy if it exists. In this connection, the Islamic prayer discipline has potential to alter brain physiology, based on variations in blood flow to this organ, known to be highly sensitive to same. The variations would come about as a result of the highly regimented posture changes occurring during Islamic prayer. I have coded these postures according to the probable effect on blood pressure measured at the brain, and the result looks like this:

Picture 2. The inferred brain physiology of Islamic prayer. Source of data: YouTube, "Time to pray with Zacky," accessed 05-23-2019.

 Shown are my inferred variations in brain oxygenation during two rakat, or units of prayer. Bowing is coded the same as sitting, namely 1. Prostration is coded as 2 and standing is coded as 0. Some forms of Islam prescribe up to 19 rakat per day. Special procedures (Sujud Sahwi) exist for fixing prayers performed erroneously due to "forgetfulness" but this "forgetfulness" I find suggestive of temporary brain dysfunction due to lack of oxygen from getting up too quickly, possibly at about minute 2, above.

The above observation is to help establish that Islamic prayer manipulates a variable that matters, always an important issue at the outset of a research project. You don't want to waste taxpayer money blindly researching variable after variable and concluding at great expense merely that none of them was relevant.

#47. Science and Proto-science [evolutionary psychology]

EP

Red, theory; black, fact

Is protoscience fundamentally playful?

Why does religion continue to be so popular in today's supposedly enlightened age? In what category of things should we place religion for purposes of analysis? The least bad answer that I have come up with is: "Religion is the last protoscience."

Protoscience is most easily defined by a few well-known examples: alchemy and astrology. These disciplines can be thought of as crude, primordial versions of chemistry and astronomy, respectively, and unable to quickly divest themselves of bad theories due to an over-reliance on aesthetics as a way to truth.

If religion is a protoscience, that then, is the corresponding science? Will religion someday transform into some kind of super-science, marvelous beyond all prior imagining, and capable of robustly duplicating all the miracles of Christ, just for starters?

The science that could replace the protoscience religion is likely to be the study of adaptive, distributed, and unconscious behavioural effects in human populations. This will be a division within sociobiology focused on human swarm intelligence acting on an historical time scale. From my own examined experience, I have reason to believe that such things exist. 

Historical Protosciences

Alchemy is thought to have become chemistry with the isolation of oxygen in pure form by Priestly, which was quickly followed by its recognition as an element by Lavoisier, who had met Priestly in Paris and learned of the new "air" direct from the discoverer. This clue led Lavoisier to a correct theory of the nature of combustion. Priestly published his discovery of oxygen (Lavoisier's term), which he called "dephlogisticated air" (an alchemical term), in letter form, in 1775.

The corresponding intellectual hand-off from astrology to astronomy seems to have been from Tycho Brae (1546-1601), who seems to have been much involved with astrology, to his assistant Johannes Kepler (1571-1630; "The Legislator of the Heavens"), who derived three famous mathematical laws of planetary motion from Brae's data.

Where Are They Now?

While the former astrology continues to this day as basically a form of amusement, and the former alchemy has utterly perished (as theory, not practice), religion continues to pay its way down the time stream as a purveyor of a useful approximate theory.

The Longevity of Religion

An approximate theory is useful to have if all you need is a quick and dirty answer. The theory that the Earth is flat is an approximate theory that we use every time we take a step. The corresponding exact theory, that the Earth is spherical and gravitating, is only needed for challenging projects such as travelling to the moon.

The God Hypothesis

Thus, the God hypothesis is the theory of natural selection seen "through a glass darkly." However, the experiences contributing to the formulation of the God hypothesis would have been due to any cause of seemingly miraculous events over the horizon or beyond the reach of individual memory. This would comprise a mixture of the fastest effects of evolution and the slowest effects of synaptic plasticity/learning (e.g., developmental sensitive periods). However, the capacity for learning is itself due to natural selection and learning is, like natural selection, a trial-and-error process. Thus, the two sources of biological order hinting at the existence of God should usually be pulling in the same direction but perhaps with different levels of detail. Modern skepticism about religion seems to be directed at the intellectual anchor point: the God hypothesis. Since I believe that they are best de-faithed who are least de-faithed, let us simply shift the anchor to natural selection and carry on.

Future Directions

I think it premature to abandon classical religion as a source of moral guidance before evolutionary psychology is better developed, and given the usefulness of approximate theories, complete abandonment may never be practical. However, in our day, humanity is beset with many pressing problems, and although atheism appears to be in the ascendent, it may be time to integrate religion with science so as not to throw out any babies with the bathwater.

The Practices May Outlive the Protoscience

The modes of worship in use in many modern religions may well confer psychological benefits on the pious not yet suspected or articulated by mainstream science. Scientific investigation of the modes of worship that many religions have in common seems in order, especially since they amount to folk wisdom, which is sometimes on the money. Examples of common practices that seem to have potential for inducing neurophysiological changes are prayer, fasting, pilgrimage, incense-burning, and even simple congregating.

#42. A Discovery of Hackers [population, evolutionary psychology]

PO   EP

Red, theory; black, fact

The hacker phenomenon may be psychologically and sociologically akin to what was once called witchcraft, and I think witchcraft is a scientifically accessible social phenomenon. 

The Past

However, the height of the witchcraft hysteria in Europe occurred during the Sixteenth century, when there were no computers. (I focus on Europe here because my ancestors came from there as did those of most people I know.) It was, however, a time of unprecedented scientific advance, and if science paced technology then as now, quite a few new technologies were coming into knowledge for the first time.

The Future

I suggest that the defining toxic ingredient in black-hat hacking is new technology per se. We should therefore expect that with time, computer hacking will spread to new-technology hacking in general and that the computer-centric version must be considered the embryonic form. This is bad news because there has never been so much new technology as now, but at what point in history has this not been true?

The Mystery of Witch Hysteria

Belief in and persecution of witches is so widespread across human cultures that it must be considered a cultural universal. Scholars focus on the persecution part, blithely assuming that there is absolutely nothing real driving it, and that the subject people of the study are, by implication, gullible and cruel. Is this stance elitist? Never judge a man until you have walked a mile in his shoes. Those people all have brains in their heads built to the exact same design as our own, and the role of education may be overrated when cultural universals are in play.

A Contemporary Interpretation 

The defining idea of the witches/technology hackers may be viewing new technology as a possible means to increase personal power. After siege mentality sets in, fear of apprehension and punishment leads to a mad-dog rejection of all morality, like a gambler chasing the money, or in this case, the indemnity. 

A Contemporary Interpretation of Black Magic

A technology ideal for hacking/witchcraft must be usable without the identity of the agent coming into general knowledge, and is thus  similar to the ring of Gyges mentioned in Plato's Republic. The anonymity conferred by the Internet makes it one of our worst rings of Gyges.  More will be discovered in other realms of technology as the hackers branch out, perhaps in alliance with the currently popular Maker movement. 

How common are Gygean technologies? Hard to say, but it may help to list some.

• Ionizing radiation was known from the work of Roentgen in 1895 (x-rays) and Villard in 1900 (gamma rays) and for the first time, a means to destroy healthy, living tissue silently and through walls solid enough to conceal all signs of the agent, had become available. 
• The lead pencil, introduced in the Sixteenth century already alluded to, was originally made with actual lead metal instead of graphite and clay mixtures, which we now know to be insidiously neurotoxic, especially to children--knowledge to warm the heart of any proper witch.
• In the time of Christ in the Middle East, the Roman occupiers knew of ten or so plant-derived poisons, including opium. The very concept of a poison could have been new in those days, and poisons are the classical hard-to-detect weapons. If the weapon is hard to detect, so is the agent. A crypto-technological explanation for some of the events of the New Testament seems possible.

Gygean weapons are doubly "invisible" when based on new technology because these modus operandi are not yet on anybody's radar, so the first x number of people who spot them are likely to be disbelieved and their sanity questioned.

Witches have always operated in the zone of perceptual blindness to abuses that transiently opens up after the introduction of any new technology. The psychological invisibility of weapons based on new technology is probably the factor that led witches to become associated with magic. 

Psychological Aspects 

Moreover, since the technology is unprecedented in human evolution, the levels of resentment that become inducible in the victims are potentially unprecedented and unphysiologically intense, leading to grotesquely disproportionate punishments being meted out to discovered witches, and this for strings of crimes that would have been extremely serious even considering strictly proportionate punishments. The historical accounts of witch-burnings may have all been cleaned up for a squeamish readership.

Why were a majority of European accused witches female? It is probably relevant that the female-specific scold’s bridle was in use at this time. At the height of the anti-witch hysteria, the Catholic Church was pushing back against the Protestant Reformation, and yet Catholicism was relatively tolerant of witchcraft. The most witch trials per capita were in high-latitude or high-altitude countries (e.g., Norway, Scotland, Switzerland) that would have been most affected by the  “little ice age” of the 1600s. Other crimes like theft and murder surged when witchcraft did. I’m not sure what all this adds up to beyond a society under stress.

The Present

Today, the hackers are mostly male and the demographic challenge is too many people, not too few. Calhoun's overpopulation experiments on rodents imply that people will become more aggressive if forced to live at higher population densities, and such a relentless increase in aggressiveness may be driving the current reemergence of the witch/hacker. 

It doesn't help that organized religion, the traditional enemy of witchcraft, is withering on the vine in this country, probably due to the intellectual fallout from Darwin's theory of evolution combined with the failure of the public to understand that a scientific world-view is never finished and may some day substantially validate the claims of religion after some reinterpretation of terms.

#41. Corporate Sin [evolutionary psychology]

EP

Red, theory; black, fact

Not all of humanly willed destruction is due to two persons interacting, either in a sadness cycle or an anger cycle. Wars of depopulation and wars of dispersal represent these interactions promoted to the level of entire societies. This promotion theory assumes that the same hard-wired wetware is being used for both levels, but with the addition of a few more bits of code to support the social level.

Theologians such as Bishop Baycroft, writing in "The Anglican Way," are well aware of this extra dimension of human misery, referring to it as "corporate sin," and admit that it is a more difficult problem than individual sin. The advice I give in "Signaletics for Salvation" will not help you efficiently if your unhappiness has its roots in corporate sin (for example, if you are caught up in a military draft or are a slave), but it may be better than nothing. What about those extra bits of code?

The basic code design seems to be to transform a tiff between two individuals into a tiff between two leaders, then copy the emotions of the leaders into the heads of all the followers on both sides. Thus, a political leader is a kind of emotional conductor. This is why we have leaders.

By this theory, World War II was a tiff between Adolf Hitler and Winston Churchill, both famous for their speeches in which they inspired passions in their followers.

How do you get to be leader? The simplest answer seems to be that you just get famous and you are also someone who doesn't see a way to end his pain without involving the whole world. 

An attractive theory about fame, in turn, is that fame is 90% being-famous-for-being-famous, and 10% is being famous for something else, the predisposing factor. Human intergroup interactions have the form we observe because these predisposing factors are not random but are due to natural selection. Moreover, they are conditional upon prevailing conditions, such as the price of bread relative to wages. Finally, they already exist at the individual level. The process of garnering the absurd 90% of fame is the by-now familiar phenomenon of going viral, and its earlier historical equivalents. 

I imagine that this process is a positive feedback loop in the brain that involves the attentional system and Hebbian plasticity, the latter well known for having a built-in positive feedback. We also know that emotions are contagious (See: Hatfield E, Cacioppo JT, Rapson RL. Emotional Contagion. New York: Cambridge University Press, 1994).

#37. The Fallacy of Justice [evolutionary psychology]

EP

Red, theory; black, fact

The Biology of Badness

Evil and criminality may sub-serve either dispersal or preemptive population reduction, both valuable biological processes that tend to prolong the survival of species. 

The algorithms for achieving these ends would have been created over time by some form of evolution.

Evolution and the Role of Emotion

The genetically inherited parts of our behavior enter consciousness as emotions, and can therefore be easily identified. The main outlines of civilization are probably due to the inherited behavior component, and not to the reasoning, conscious mind, which is often just a detail-handler. How could civilization rest on a process that can't even remember what happened last weekend?

Thus, humans have a dual input to behavior, emotion and reason. The above arguments show that evil and criminality come from the emotional input. Yet the entire deterrence theory of justice assumes the opposite, by giving the person a logical choice: "You do this, we do that, and you won't like it. So you don't do this, right?"

However, I think that people commit crimes for emotional reasons. As usual, the criminal's reasoning faculties are just an after-the-decision detail handler. The direction that this detail handler then takes is fascinatingly monstrous, but this does not mean that crime begins in reason.

Conclusion: the deterrence theory of justice is based on a category error.

Past and Future Responses to Badness

Religion, with its emphasis on emotion, was all the formal "law enforcement system" anyone needed up until only about 200 years ago, at the industrial revolution. We may be able to go beyond where religion takes us by means of a disease model of criminality.

It does make some sense to lock criminals up, because with less freedom they cannot physically commit as many crimes. Many prisons become dungeons, however, because of the public's desire for revenge. However, all revenge-seeking belongs to the dispersal/depopulation dynamic and is thus part of the problem. A desire for revenge may follow a crime very predictably, but logically, it is a non-sequitur.

A more nuanced theory of crime prevention is possible, where logical and technological constraints on behavior complement efforts to reduce the motivation for committing crimes at the source: the individual's perception of the fairness of society, which will be due to a combination of objective realities and the filters through which they are viewed. However, I originally wrote as I did because I don't think that logical and technological constraints are the squeaky wheel at the moment.

#21. The Cogs of Armageddon [evolutionary psychology]

EP

Red, theory; black, fact

The Mechanism of Human Dispersal 

How does everyday human behaviour eventually accomplish the biological function of dispersal for the human race? 

Background 

Dispersal is things like dandelions shedding airborne seeds, slime molds developing into spore cases on stalks and releasing the spores into the wind, territorial systems of birds and mammals forcing the unlanded young to seek widely for their own territories, and humans going into space because our science fiction writers keep scaring us about the possibility of meteor crashes wiping out life on Earth. 

The slime mold Dictyostelium is triggered into its dispersal program by the food supply running short; I will adopt the assumption that the human dispersal program is also triggered by the end of the good times, that is, the price of bread rising relative to wages.

The Psychology of Dispersal

Human neural pathways may potentiate aggression when the hard times come, but of an elaborate kind featuring many evolved adaptations that ensure efficient dispersal (i.e., with minimal loss of life). 

Our evolved dispersal program begins with a two-person feud of the sort illustrated in cultural references too numerous to mention. An arbitrary stimulus, made offensive by some piece of Pavlovian conditioning, is traded back and forth with rapidly increasing energy. 

Features of Human Dispersal Explained by Evolution 

1) The emotional component is strongly threatening because the participants must be induced to seek allies, which people do when  threatened, until all of society is eventually polarized. The acts of provocation being traded back and forth become progressively more outrageous, as they must, to keep the polarization process going. Eventually, one side gets the upper hand and forces the other to flee.

2) The result is a diaspora, i.e., dispersal. Because of the long polarization process, an entire group is expelled, not single individuals one at a time. Thus, members of such a group can assist each other to survive and relocate, thereby reducing the mortality associated with dispersal, thereby making the dispersal event more efficient in terms of number of people relocated.

3) The group who flees is then seen by the international community as the blameless victim, and the group who stays is seen as the unprincipled aggressor. This tends to elicit a sheltering of the refugees and an intimidation of the "aggressor," who is deterred from pressing his advantage, that is, pursuing the refugees and slaughtering them to the last man, which is what each side would like to do to the other by this point. This, again, is an efficiency from the point of view of producing dispersal.

4) However, if each side is continually threatening the other, why don't they flee each other's presence during the very early stages? Humans may have a reflex that converts feeling threatened into a wish to injure the threatening party, possibly a behavioural leftover from some earlier adaptation, such as an anti-predation defence. To injure, you have to stick around. 

5) Finally, settled refugees usually do not integrate completely into the host society, instead forming ethnic neighbourhoods. Being seen as ethnic by the host society, due to slow integration, could improve the reproductive success of refugees because of disassortative mate-choice effects evolved to favor genes that produce dispersal.

6) The dispersal-producing dynamic just outlined is powerful, because it must overcome all the reasons a person would not leave their homeland forever at some arbitrary time: expense, risk of mortality in transit, opportunity costs, temporary loss of livelihood, need to learn a new language and customs, vulnerability to exploitation in the new country, etc.

#17. Hell's Kitchen [evolutionary psychology]

EP

Red, theory; black, fact

Ever since the assassination of JFK in '63, people of my generation have been wondering why the Americans kill off their best and brightest. It's not just the Americans, of course. The same thing happened to Gandhi and Our Savior no less.

I think a homey kitchen metaphor nails it. Once you have emptied the milk carton of all its milk, you can use it to dispose of the grease. That is, by the logic of "The Insurance of the Heart," once tremendous acclaim has been conferred on someone's name, the physical person no longer matters for the purposes of enhancing the name their descendants will inherit, and so can safely be used to draw the fire of the genetic undesirables; the resulting tremendous indignation will confer bad odor on the name of said undesirable for quite long enough to eradicate their meh genes in all copies.

Thus, Booth's genes were eradicated to make way for Lincoln's, and Oswald's genes were eradicated to make way for Kennedy's, without overall change in population density.

If the intermind could be said to have thoughts, this is what they would be like. Clearly, it's not God.

#16. The Intermind, Engine of History? [evolutionary psychology]

EP

A Mechanism of Rapid Evolution 

A plausible reason for having a mechanism of rapid evolution is that it permits evolutionary enlargement of body size without loss of evolvability; larger size leads to more internal degrees of freedom and therefore access to previously impossible adaptations. For example, eukaryotes can phagocytose their food; prokaryotes cannot. However, larger body size comes at the expense of longer generation time, which reduces evolvability. A band of high frequencies in the spectrum of environmental fluctuations therefore develops where the large organism has relinquished evolvability, opening it to being out competed by its smaller rivals. 

What I call the intermind would be a proxy for classical evolution that fills the gap, but it needs an objective function to provide it with its ultimate gold standard of goodness of adaptations. Species-replacement group selection could ensure that the objective function is close to optimal. This group selection process takes place at enormously lower frequencies than those the intermind is tracking, because if the timescales were  too similar, chaos would result. For example, in model predictive control, the model is updated on a much longer cycle than are the predictions derived from it.

This genetic intelligence may construct our sociobiology in an ad hoc fashion, by rearranging a knowledge base, or construction kit, of rules of conduct into algorithm-like assemblages. This rearrangement would be blindingly fast by the standards of classical Darwinian evolution, which only provides the construction kit itself, and presumably some further, special rules equivalent to a definition of an objective function to be optimized. The ordinary rules translate experiences into the priming of certain emotions, not the emotions themselves, 

Its Properties 

The set of ordinary rules or intermind would be intermediate in speed between classical evolution and learning by operant conditioning. (All three depend on trial-and error.) The name is also appropriate in that the intermind would be a distributed intelligence, acting over continental, or a least national, areas. Its objective function, which is simply whatever produces survival, will be explicitly encoded into the genes specifying the intermind. (For more on multi-tier, biological control systems with division of labor according to time scale, see "Sociobiology: the New Synthesis," E. O. Wilson, 1975 & 2000, chapter 7.)

Evil Explained

The intermind may account for evil because it is only concerned with survival of the entire species and not with the welfare of individuals.

Evolutionary Mechanisms 

The intermind will have been created by group selection of species. Higher taxonomic units such as genus or family will scarcely evolve because the units that must die out to permit this are unlikely to do so, because they comprise relatively great genetic and geographical diversity. However, we can expect intermind-related adaptations that facilitate the creation of new species, the units of selection. Imprinted genes may be one such adaptation, which might enforce species barriers by a lock-and-key mechanism that kills the embryo if any imprinted gene is present in either two or zero active copies. Species-replacement group selection need act only on the objective function used by trial-and-error processes.

What Are Its Objectives?

In these times, we have come to know that species survival is imperiled by loss of range and by loss of genetic diversity. Thus, the objective function will tend to produce range expansion (exploration in humans) and optimization of genetic diversity. 

However, all this is insufficient to explain the creativity of humans, starting at the end of the last ice age with cave paintings, followed shortly thereafter by the momentous invention of agriculture. The hardships of the ice age must have selected genes for a third, novel component, or pillar, of the species objective function, namely optimization of memetic diversity. Controlled diversification of the species memeplex may have been the starting point for cultural creativity and the invention of all kinds of aids to survival. Art forms may represent the sensor of a feedback servomechanism by which a society measures its own memeplex diversity, measurement being necessary to control.

Insurance-like Adaptations

We live in an uncertain world, the best reason to buy insurance while you can. Insurance is too good a trick for evolution to have missed. When food is plentiful, as it now is in my country, people get obese, as they are now doing here, so that they can live on their fat during possible future hard times. They don't do this consciously; it's in their genes.

However, eating foregone during hard times has only a subtractive effect on your footprint on society's demand for scarce resources; how many kids you have affects your footprint multiplicatively. Thus, the effectiveness of biological insurance taken out in children foregone during times of plenty would be greater than that taken out in food consumed in advance.

The Role of Reputation 

Building on the multiplicative mechanism, the existence of which I am simply assuming, a still more powerful insurance mechanism exists; how well and long remembered the family name is that you bequeath to your children affects your footprint exponentially. I assume that a good or bad "name" affects the reproductive success of all your descendants having that name until you are finally forgotten. Compared to exponential returns, everything else is chump change. ("Who steals my purse steals trash." - Shakespeare)

Advance Evolution 

There remains the problem of food going to waste during times of plenty because the social forces associated with the multiplicative mechanism prevent a quick population increase. I conjecture that the extra energy available is invested by society in contests of various sorts, for example, the Circus Maximus during the heyday of ancient Rome, that act as a proxy to evolutionary selection pressure, whereby the society accelerates it's own evolution. Although natural selection pressure is maximal during the hard times, relying on these to do all your evolving for you can make you extinct; better to do some "preventative evolution" ahead of time.

Since future environmental demands are partly unforeseeable, a good strategy would be to accelerate one's evolution in multiple directions, keeping many irons in the fire. Indeed, in the Olympics just concluded, thirty-nine sports were represented.

Evolutionary Psychology 

The power of these contests is maximized by using the outcomes as primary conditioned stimuli that are associated with the family names of the winners and losers: the secondary conditioned stimuli. In this way, one acquires a good or bad "name" that will affect the reproductive success of all who inherit it, an exponential effect. To ground this discussion biologically, it must be assumed that the contests are effective in isolating carriers of good or bad genes (technically, alleles), and that the resulting "name" is an effective proxy for natural selection in altering the frequency of said genes. To keep the population density stable during all this, winners must be balanced by losers. The winners are determined and branded in places like the tennis courts, and the losers are determined and branded in the legal courts.

#3. Human Reproductive Control [population, engineering, evolutionary psychology]

Red, theory; black, fact

Here, I go into detail about the human population controller introduced in the previous post.

The Relevance of Engineering 

I assume that this controller is a masterful piece of engineering, like everything in the natural (i.e., evolved) world, as Leonardo Da Vinci declared.

Application of Filter Theory

The way to build an ideal feed forward controller is the inverse plant method, where the controller contains the mathematical inverse of a mathematical model of the system to be controlled.  To derive the model, you take the Laplace transform of the system's impulse response function. For populations, a suitable impulse would be the instantaneous introduction of the smallest viable breeding population into an ideal habitat.

The Impulse Response Function 

What happens then is well known, as least in microbial life forms too simple to already have a controller: unrestrained, exponential population growth as per Malthus, with no end in sight.

This exponential curve is then the impulse response function we need, and its Laplace transform is simple: 1/(S - r), where S is complex frequency and r is the Malthusian constant, that is, percent population growth per year. 

The Inverse Model

The mathematical inverse is even simpler: S - r, which is multiplied by the sensor-error Laplace transform to get the controller output. Multiplication by S followed by subtraction of the zero-time signal is equivalent to differentiation in the time domain. The effect of S-domain subtraction and multiplication by a constant remain the same when transferred to the time domain.

In humanly engineered systems, a feedforward controller typically operates in conjunction with a downstream feedback controller.

  

The Sensor Signal

The level of the noise produced so copiously by small children is probably the signal that people unconsciously use to estimate birth rate, and the wailing and long faces following a death probably serve the same purpose for estimating death rate.  My married older brother once showed me the developmental time course of child noise in the air with his hand, and it looked like an EPSP, the response of a neuron to an incoming action potential. The EPSP is the convolution kernel by which a neuron decodes a rate code. This suggests that the differentiation operation is telescoped into the sensing operation.
