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



Red, theory; black, fact.

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? This is a very important question. The least bad answer that I have come up with is: "Religion is the last protoscience." (By this I mean "classical protoscience"; a contemporary field of study, string theory, has also been labelled "protoscience," a result I base on a DuckDuckGo search on "Is string theory a protoscience?" on 20 Feb, 2022.)

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 laughably 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?

08-03-2020: Formerly at this location, now deprecated: Religion is the protoscience of origins and Darwin's theory its successor via the clergyman Malthus. Malthus was one of Darwin's influences, as attested explicitly in the writings of the latter.

07-26-2020: The science that could replace the protoscience religion is likely to be the study of adaptive, distributed, and unconscious behavioral effects in human populations. <07-30-2020: 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. I called them "macro-homeostatic effects" in the post "The Drill Sergeants of the Apocalypse."

Alchemy is thought to have become chemistry with the isolation of oxygen in pure form by Priestly, followed in short order 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.

06-28-2019: 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 onetime assistant Johannes Kepler (1571-1630; "The Legislator of the Heavens"), who derived three famous mathematical laws of planetary motion from Brae's data.

While the former astrology continues to this day as basically a form of amusement and favorite whipping-boy of sophomores everywhere who are just discovering the use of their brains, 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.

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.

03-13-2020: 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.

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 reconcile religion with science, so as not to throw out any babies with the bathwater.

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.

#47. Body-mod Bob's [evolution, evolutionary psychology]




EV     EP     
Red, theory; black, fact.

In the previous post, "Goddesses of the Glacier," evolution appears to be operating in cooperation with a general capacity for technology. Natural selection operates on the brain pathways underlying our aesthetic preferences concerning our own appearance and that of possible reproduction partners and then a technology is automatically developed to satisfy them.

As a first example, consider the oil and brush technology previously assumed for differentiating women from men by hair smoothness. A further step in this direction is to posit that hair color may have been used to code gender. The first step would have been selection for a blond(e) hair colour in both women and men. Since this is a very light colour, it will show the effect of dyeing maximally. Concurrently with this, the aesthetic preferences of men and women would have been differentiated by selection, resulting in blonde women who experience a mild euphoria from being blonde and blond men who experience a mild dysphoria from the same cause. The men would predictably get busy inventing hair-dyeing technologies to rectify this. The necessary dyes are readily obtained from plant sources such as woad and walnut shells. The result would be an effective blonde-female/nonblond-male gender code.

This style of evolution could be very fast if the brain pathways of aesthetic preferences require few mutations for their modification compared with the number required for the equivalent direct modification of the body. Let us assume this and see where it leads.

Faster evolution is generally favored if humans are typically in competition with other species to be the first to occupy a newly possible ecological niche. Such niches will be created in abundance with every dramatic change in the environment, such as a glaciation and the following deglaciation. Possibly, these specific events just slide the same suite of niches to higher or lower latitudes, but the amount of land area in each is likely to change, leading to under-capacity in some, and thus opportunity. These opportunities will vanish much faster than evolution can follow unless a diversity of phenotypes is already present in the prospective colonizing population, which might happen as a result of genetic drift in multiple, isolated sub-populations.

If technologically assisted evolution has general advantages, then we can expect its importance to grow with increases in the reach of technology. Today, we seem to be at a threshold, with male-to-female and female-to-male gender transitions becoming well known. Demand for this service is probably being driven by disordered neural development during fetal life due to contamination of the fetus by environmental pollutants that have estrogenic properties (e.g., bisphenol A, PCBs, phthalates, etc.). The result is the birth of individuals with disordered and mutually contradictory, gendered aesthetic preferences, which is tragic. However, it is an interesting natural experiment.

With further development of cell biology in the direction of supporting body-modification technology, who knows what bizarre hankerings will see the light of day on demand from some customer? Remember that in evolution, the mutation comes first, and the mutation is random. Predictably, and sadly, most such reckless acts of self-indulgence will be punished by reduced employability and reduced reproductive success, doubtless exacerbated by prejudice on the part of the normal, normative majority.

However, the very occasional success story is also to be expected, involving the creation of fortuitously hyperfunctional individuals, and thus the technologically assisted creation of a new pre-species of human.

If the engineering details learned by the body-modification trade during this process are then translated into germ-line genetic engineering, then a true artificial humanoid species will have been created.

#46. The Goddesses of the Glacier [evolutionary psychology]

Sorry, not found on Unsplash. (Spirits are flying in bearing mukluks and a parka.)


Red: theory; black, fact.

This post is about long hair, of all things (which I totally dig), and I will argue that humans evolved the trait to keep them warm during geologically recent continental glaciations. (Please pardon the teleological phrasing; I use it here only for the sake of brevity.)

Can having long hair really confer such a benefit under cold conditions? The anecdotal evidence supporting this idea seems abundant. For example, go to the site shown below
for a near-unanimous list of affirmative replies to the question: ‘Does long hair keep you warm?’ One respondent in particular (#32), from Sweden, seems to have exactly reproduced the method for ensuring this that must have been used in eras of glaciation, assuming that our distant forbears could at least make themselves simple parkas out of animal skins.

They would have supplemented this protection by tucking their long hair down inside the parka. Leaving it outside would have been good fashion but bad engineering, since the locks would have been quickly parted by the first gust of wind and precious, life-saving body heat lost.

I began this with mention of goddesses, but of course the males would have had long hair too, probably a meter long, in outrageous violation of modern gender expectations concerning hair length.

I find that this situation suddenly makes better aesthetic sense if you imagine this long hair as tousled in the males and smooth and perfect-looking in the females (and perhaps only in the portion showing above the neckline.) Seen this way, both males and females look gorgeous in the imagination and the aesthetic problem is solved. I call this the "rock-star solution." The females could have smoothed their hair by lubricating it with oil and brushing, and a brush is not hard to make. Meanwhile, the males would only need their fingers for cultivating a charming, insouciant look.

While moderns socially code gender as hair length, this parameter was unavailable to our glaciation-era forebears (the last glaciation maximum occurred 26,000 years ago) because they would have been unwilling to cut their hair, knowing at some level of insight that they needed it for survival and mating success. Therefore, they might have coded gender as hair smoothness as described above. 

I assume that these people were living in some glaciation "refugium," as such terrain is technically called, which is a fortuitously ice-free zone surrounded by continental glacier.

While writing this, I was struck by the amount of detailed information I was able to retrieve from my own aesthetic preferences, some of which would have evolved under stringent, cold-climate conditions to produce mate choices favoring traits with survival value. 

The heart may have its reasons that reason knoweth not, but reason is learning*.

11-26-2019 I have not mentioned beards yet and the main question there is why women do not have them. The answer seems to be that a long beard would interfere with breastfeeding, whereas long scalp hair can be pushed back. Moreover, women have more subcutaneous fat than men, so their thermoregulation problem in a cold climate would not be as severe.

#45. The Denervation-supersensitivity Theory of Mental Illness [neuroscience, evolution, genetics]

NE     EV     GE     
Red, theory; black, fact.

People get mental illness but animals seemingly do not, or at least not outside of artificial laboratory models such as the unpredictable, mild-stress rodent model of depression. A simple theory to account for this cites the paleontological fact that the human brain has been expanding at breakneck speed over recent evolutionary time and postulates that this expansion is ongoing at the present time, and that mental illness is the price we are paying for all this brain progress.

In other words, the mentally ill carry the unfavorable mutations that have to be selected out during this progress, and the mutation rate in certain categories of mutation affecting human brain development is elevated in modern humans by some sort of "adaptive" hot-spot system. "Adaptive" is in scare quotes here to indicate that the adaptation inheres in changes in the standard deviation of traits, not the average, and is therefore not Lamarkian.

In brain evolution, the growth changes in the various parts very probably have to be coordinated somehow. I conjecture that there is no master program doing this coordination. Rather, I conceive of the human brain as comprising scores of tissue "parcels," each with its own gene to control the final size that parcel reaches in development. (This idea is consistent with the finding of about 400 genes in humans that participate in establishing body size.) All harmonious symmetry, even left-right symmetry, would have to be painstakingly created by brute-force selection, involving the early deaths of millions of asymmetrical individuals. This idea was outlined in post 10.

Assuming that left and right sides must functionally cooperate to produce a fitness improvement, mutations affecting parcel growth must occur in linked, left-right pairs to avoid irreducible-complexity paradoxes. I have previously conjectured in these pages that the crossing-over phenomenon of egg and sperm maturation serves to create these linked pairs of mutations, where the two mutations are identified with the two ends of the DNA segment that translocates. (See "Can Irreducible Complexity Evolve?")

Most of the evolutionary expansion of the human brain appears to be focused on association cortex, which I conjecture implements if-then rules, like those making up the knowledge bases familiar from the field of artificial intelligence. The "if" part of the rule would be evaluated in post-Rolandic cortex, i.e., in temporal and parietal association cortices, and the "then" part of the rule would be created by the pre-Rolandic association cortex, i.e., the prefrontal cortex. The white matter tracts running forward in the brain would connect the "if" part with the "then" part, and the backward running white-matter tracts would carry priming signals to get other rules ready to "fire" if they are commonly used after the rule in question.

Due to such tight coordination, I would expect that the ideal brain will have a fixed ratio of prefrontal cortex to post-Rolandic association cortex. However, the random nature of the growth-gene bi-mutations (perhaps at mutational hot-spots) permitting human brain evolution will routinely violate this ideal ratio, leading to the creation of individuals having either too much prefrontal cortex or too much temporal/parietal cortex. In the former case, you will have prefrontal cortex starved of sensory input. In the latter case, you will have sensory association cortex starved of priming signals feeding back from motoric areas.

Denervation supersensitivity occurs when the normal nerve supply to a muscle is interrupted, resulting in a rapid overexpression of acetylcholine receptors on the muscle. This can be seen as an attempt to compensate for weak nerve transmission with a tremendous re-amplification of the signal by the muscle. Analogous effects have been found in areas of the cerebral cortex deprived of their normal supply of sensory signals, so the effect seems to be quite general.

In cases of genetically-determined frontal-parietal/temporal imbalance, I conjecture that the input-starved side develops something like denervation supersensitivity, making it prone to autonomous, noise-driven nervous activity.

If the growth excess is in sensory association cortex, this autonomous activity will manifest as hallucinations, resulting in a person with schizophrenia. If the growth excess is in the prefrontal cortex, however, the result of the autonomous activity will be mania or a phobia. Depression may originally have been an adaptation to the presence of a man-eating predator in the neighborhood, but in civilized contexts, it can get activated by the unpredictable (to the sufferer) punishments resulting from manic activity. If the mania is sufficiently mild to co-exist with depression, as in type II bipolar disorder, then the overall effect of the depressive component may be like a band-aid on the mania.

The non-overgrown association cortex might even secondarily develop the opposite of denervation supersensitivity as the result of continual bombardment with autonomous activity from the other side of the Rolandic fissure. This could account for the common observation of hypoprefrontality in cases of schizophrenia.

#44. Sunshine in Covey's Gap [evolutionary psychology, neuroscience]

EP     NE     
Red, theory; black, fact.

Who has not felt frustration at the difficulty and seeming impossibility of making a disagreeable emotion go away before we weaken and act it out, to our detriment? Techniques of true emotional control, i.e., making the bad feelings disappear rather than white-knuckle, open-ended resistance to acting them out, are not impossible, just non obvious. You just have to persuade yourself that this bad is good and believe it.

For the modern person, that second part, the believing, is difficult to achieve robustly if one is using religious solutions to the problem, the domain of soteriology (being "saved"), easier with psychoanalytical solutions, and, I am here to say, easiest of all with scientific solutions. "Believing," for me, means being prepared to bet your life on the truth of a proposition.

Steven Covey writes in "The Seven Habits of Highly Effective People" that between stimulus and [emotional] response, humans have, somewhat metaphorically, a "gap" in the causal chain and animals do not. In the gap, you find such things as imagination, self-awareness, conscience, and self will. He correctly lays tremendous emphasis on this point. George Santayana seems to have grasped this truth when he wrote: "Our dignity is not in what we do but in what we understand. The whole world is doing things." [source, Wiki quotes, accessed 11-06-2018]

Neuroscientist Joseph LeDoux has even elucidated what could be the neural pathways that make Covey's gap possible. A direct pathway from the thalamus to the amygdala mediates the basic fear response but an indirect pathway that leads from thalamus to cerebral cortex to amygdala provides a more nuanced, intelligent amendment to the first response. Full cancellation of the direct pathway by the indirect would account for Covey's gap, and in principle, this could be done by a cortical relay through the inhibitory interstitial neurons of the amygdala that terminate on the amygdalar projection cells.

The doctrines of classical religion probably lead to such cancellation of emotions such as hate and fear by activating the same circuits that are used by a parent to reassure a needlessly fearful infant.

Apparently, classical religion is all about getting people to do the right things for the wrong reasons. When the discipline of evolutionary psychology is sufficiently developed, we can look forward to the age when people do the right things for the right reasons.

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

PO     EP     
Red, theory; black, fact.

9-07-2018: I was saving this for the Sunday before Halloween, but decided that it couldn't wait. The basic idea of this post is that the hacker phenomenon is psychologically and sociologically akin to what was once called witchcraft. Let me hasten to clarify that I am talking about witchcraft the social phenomenon, because I don't believe in anything supernatural. 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.

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 statement not been true?

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, a bunch of blithering idiots, and sadists to boot. I find this stance elitist. Never judge a man until you have walked a mile in his shoes. These 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.

I suggest that the defining idea of the witch/technology-hacker (tacker) is viewing new technology as a possible means to increased personal power. To produce a tacker, this idea must be combined with a mad-dog rejection of all morality. 

A technology ideal for tacking/witchcraft must be usable without the identity of the agent coming into general knowledge, and is thus sociologically 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, but just wait. More will be discovered in other realms of technology as the hackers branch out, perhaps in unholy alliance with the currently popular Maker movement. Makers, wake up! It's not too early for a manifesto!

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. (See my blog "Journalist's Progress," at (Link under reconstruction)https://xrra.blogspot.com )
  • 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 modi operandi are not yet on any body'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. 

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. I suspect that the historical accounts of witch-burnings have all been cleaned up for a squeamish readership.

Why were a majority of European witches female? At the height of the anti-witch hysteria, the Black Death was raging and the local human population was probably having trouble keeping its numbers up. On general adaptationist assumptions, all kinds of social forces would have been working to reduce women to baby-making machines, whatever their endowments or aptitudes. This would have created an inevitable push-back in the most intelligent women to reclaim some of their personal power, and witchcraft would have seemed an attractive option for doing this.

Today, the hackers (soon-to-be tackers) 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/tacker. 

It doesn't help that organized religion, the traditional great 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.

9-08-2018: Proposed definition of "witch": a person in moral free fall under the corrupting influence of technologies that lend themselves to secret abuse for the increase of personal influence.

#42. Corporate Sin [evolutionary psychology]

Red, theory; black, fact.

7-25-2018: A moment's reflection reveals that not all of humanly willed unhappiness 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" (https://nightbull.blogspot.com) 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. But let's see what we can surmise about those extra bits of code.

The basic 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. <07-21-22: As for how I ended my own pain, minding my own business and reaching out to family at times of need seems to have sufficed. I also had a talk with my federal MP at one point.>

An attractive theory about fame, in turn, is that all fame is 90% being-famous-for-being-famous, and 10% (or less) is being famous for something else, call it the predisposing factor. Human inter group interactions have the form we observe because these predisposing factors are not random but are due to natural selection. Furthermore, 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 among students of neuroscience 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).

The final bit of code we need to produce leaders and thus corporate sin is a tendency of this contagiousness to be potentiated by the famousness of the emoter one is observing. This mechanism of social control is distinctly different from the snowball effect that I likened to a black hole in an earlier post. It will take more thinking to decide which is more accurate.

#41. The Sadness Cycle [evolutionary psychology, neuroscience]

EP     NE     
Red, theory; black, fact.

7-20-2018: This post builds on "Signaletics for Salvation," a post in the companion blog, "Experimentalist's Progress, " at https://nightbull.blogspot.com. The theory part of that post is reprinted below with slight modification for the convenience of the reader.

The anger cycle and the sadness cycle reach their full flower in wars of dispersal and wars of depopulation, respectively. These were discussed in the post "Two Kinds of War" in this blog.

Wars of depopulation serve to prevent Malthusian disasters such as general famine. The sadness cycle is a form of altruism that facilitates this depopulation by making a portion of the population sad and suicidal and the remainder contemptuous and entitled. The contemptuous ones take everything the sad ones have, ultimately their lives, and the sad ones let them.

If the sacrificial lambs were fighting what is essentially a form of cannibalism tooth and nail, the transfer of property would leave the heritors with many injuries, which would defeat the purpose of the whole process, which is to leave the residual population stronger and healthier than before under conditions of restricted food supply. However, always bear in mind that the sad ones and the contemptuous ones are playing two roles within the same adaptation; if you can play one role, you can play the other. However, if you unfortunately carry some unfavorable mutation, you will be predisposed to the sad role. This is another way the adaptation leaves the population more robust than before.

Since no altruism can evolve in the presence of selfishness unless the altruists are only altruistic to other altruists, a signaling cycle is required to lock the altruists together to the exclusion of non-altruists. Thus, sadness induces contempt and contempt induces sadness, and so on in a vicious cycle leading to the complete destruction of the sad ones and the transfer of all their property specifically to the contemptuous ones. This dynamic could be the origin of elder abuse and clinical depression.

Macchiavelli wrote, "He is made contemptible who is held to be changeable, light, effeminate, pusillanimous, irresolute, and from these the Prince must guard himself as from a reef." The traits listed appear to be the symptoms of unacknowledged sadness, and were no doubt quite lethal in Macchiavelli's time. Due to the present skyrocketing of the world population with the concomitant "Calhoun effect" from crowding stress, we are no doubt due for a remacchiavellianization of daily life. For example, should I even be sharing these insights with you instead of keeping them to myself to my own advantage or at least posting them on a commercialized blog? Does my slowness to commercialize indicate suicidally self-giving tendencies that will one day prove fatal?

6-29-2018: The Anger Cycle (reprinted)
Much of human unhappiness comes from destructive, escalating signaling cycles, usually between two persons. Examples: arguments, feuds, schools of thought, gang wars, revolutions. The signals exchanged are initially personal expressions of anger. Importantly, these expressions are multi modal, and therefore highly redundant. (e.g., threatening utterances, tones of voice, facial expressions, gait, crashing and banging things, spying, following, etc.) Your anger comes out of you "through every pore."

These signals are too many and varied for conscious control, which is why most people remain enslaved by their signals and cycles. The anger cycle is presumed to escalate until one of the parties must leave the country. When people are threatened, they seek allies, so all of society eventually gets drawn in and polarized as the escalation proceeds apace, like a black hole. Therefore, it is a group that must eventually leave, not a single individual, which is the basis of the refugee phenomenon. 

In ecological terms, the refugee phenomenon is clearly sub serving the function of dispersal. However, dispersal-producing behavior is fundamentally altruistic in a backhanded way. The benefit to the supposed loser, the group that eventually gets driven out, is that occasionally they find a newly-emptied vacant habitat in which to settle and therefore can reproduce without competition. This is a tremendous benefit in evolutionary terms and may once have been great enough to redeem all the waste and suffering of human-style dispersal. 

However, altruistic behavior cannot evolve in the presence of non-altruists unless a signaling system is established to ensure that altruists are only altruistic to other altruists. That is why I lay so much emphasis on signaling here. The reason why the signals are so multi modal is that the altruism program probably breaks down occasionally because of the short-term advantages of being a non-altruist. This has probably happened many times in the past and the broken algorithm was repaired each time by natural selection with the addition of yet another signal component. 

Multi modality implies the existence of a neuronal OR-element somewhere on the sensory side, and the amygdalae could be these OR-elements. More precisely, the amygdalae could be specialized for providing OR-elements generally to the brain by virtue of a characteristic, unique amygdalar cytoarchitecture.

7-20-2018: The various signal cycles may reinforce each other. The four signal cycles that seem to form the framework of human life seem to have such an interdependence. These are: mother-child bonding, which could potentiate man-woman bonding, which could potentiate the anger cycle (via jealousy), which could potentiate the sadness cycle. These insights come from introspection and my own biographical data.

#40. The 1950 Ramp [population, genetics, evolutionary psychology, engineering, neuroscience]

PO     EN     EP     NE     GE     
Red, theory; black, fact.

6-01-2018; 
Since about 1950, the world population has been increasing along a remarkably steady ramp function with no slackening in the rate of increase yet apparent, although one cycle of oscillation in the slope occurred during the Sixties. Malthusian reasoning predicts an exponential increase, which this is not. From several lines of evidence, I keep coming back to the idea that humans must have a subconscious population controller in their heads, and yet such a controller would have leveled out the increase by now. Until now, no theory has sufficed to explain the facts.

I here propose that the natural population curve for humans in good times is a saw-tooth waveform, with population ramps alternating with political convulsions that result in a large group being expelled permanently, resulting in the precipitous but limited drop in local population density that ends the saw-tooth cycle. This cycle accomplishes the ecological dispersal function to which I allude many times in these pages. The population must ramp up for a time to sustainably create the numbers needed for the expulsions. The WHO population curve shows only a ramp because it is a worldwide figure and therefore population losses in expelling regions are balanced by population increases in welcoming regions. This also implies that human population has been increasing in a way unrestrained by food or resource availability or any other external constraint since 1950, to now.

Clearly, human population is being controlled by instinctive factors, but not to a constant absolute density, but rather to a constant rate of increase. Population density would go up along the much faster, steeper, and more disastrous exponential curve of Malthus if there were actually no controller.

My formal training in engineering and neuroscience justifies a bit of speculation as to mechanisms at this point. Look first for such a controller in the hypothalamus, already known to control other variables, such as temperature, by feedback principles.

In school, I was taught that nature does not reinvent the wheel, which I understand to mean that once a brain structure evolves to serve a particular computational function, it will be tapped for all future needs for such a calculation. This process may make it grow larger or develop sub-nuclei, but additional, independent nuclei for the same computation will never evolve.

I will continue to assume that the controller is a conventional PID controller, as in previous posts. To make it control rate of increase rather than absolute population density, you put a differentiator in the feedback pathway. Look first in the amygdala for such a differentiator. If you are of the opinion that human population control is urgent, then you must knock out this differentiator and replace it with a simple feed-through connection. Fortunately, one common way for evolution to implement differentiation in mammals is to begin with such a feed-through connection and supplement it with an inhibitory, slow, parallel feed-forward connection. If this is the case here, then you just inhibit the feed-forward pathway pharmacologically as specifically as may be, and the job is done. Subjectively, the effect of such a drug would be to take away people's ability to get used to higher population density in deciding how many children to have. An increased propensity to riot should not occur.

I assumed in the last post that the political convulsions that produce dispersal are triggered by the value on the integrator of the PID controller rising above a threshold. However, in the above design solution, the convulsion would be triggered by the raw, undifferentiated population-density signal rising above some threshold. Look in the amygdala for this signal as well. Consistent with this, bilateral removal of the amygdalae and hippocampi in monkeys is known to have a profound taming effect accompanied by hypersexuality, known as the Kluver-Bucy syndrome.

6-17-2018: To be consistent, I would have to say that the differentiator for the population signal is more likely to be in the hippocampal formation by the argument of nature not reinventing the wheel, because in an earlier post, I interpreted the hippocampus as the site of four successive differentiations that carry out a Fourier transform by mapping sinusiodal waves back onto themselves at a particular best frequency, in the presence of a map of such best frequencies.

However, this setup would require the creation of two neuron-to-neuron connections for its evolution; a first connection to send the amygdalar raw population signal to the hippocampus, and a second to send the differentiated result back for further processing. At best, this would require two simultaneous mutations. Either change by itself would be at best useless and could never be selected. This appears to be another example of irreducible complexity requiring the bi-mutation mechanism described in the previous post. 

The mechanisms usually offered to explain cases of apparent irreducible complexity, such as spandrelling, exaptation, and scaffolding, all appear to lack time efficiency and processiveness. I previously said that in evolution there are no (absolute)  deadlines, but relative deadlines can easily be created by an interaction of processes. In the presence of relative deadlines, such as adaptive footraces to be the first clade to exploit a newly-habitable area or a new niche, time is of the essence and selection for speed and evolvability can be expected. Such selection will create mechanisms such as crossing over that enhance evolvability.

#39. Can Irreducible Complexity Evolve? [genetics, evolution]

EV     GE     
Red, theory; black, fact.

5-26-2018: Influential biologist Richard Dawkins wrote in "The God Delusion" that a genuine case of irreducible complexity will never be found in biology. A case of irreducible complexity would be some adaptation that would require an intelligent designer because it could never evolve one mutation at a time, and Dawkins believes there is no such intelligent designer in biology.

In classic natural selection, each mutation must be individually beneficial to its possessor in order for selection to increase its prevalence in the population to the point where the next incremental, one-mutation improvement becomes statistically possible. In this way, all manner of wondrous things are supposed to evolve bit by tiny bit.

However, I am seeing irreducible complexity all over the place these days. For example, your upper-jaw dentition must mesh pretty accurately with that of your lower jaw or you can't eat. Thus, the process of evolutionary foreshortening of the muzzle of the great apes to the flat human face could never have happened, assuming that a single mutation affects only the upper or lower jaw. But it did. (Let us gloss over the fact that that is an assumption, because the contrary seems to require non-local rules in development.)

Furthermore, how can any instinctive signaling system evolve one mutation at a time? At a minimum, you always need both the transmitter adaptation and the receiver adaptation, not to mention further mutations to connect the receiver circuit to something useful. The evolution of altruism presents a similar problem. The lonely first altruist in the population is always at a disadvantage in competition with the more selfish non-mutants unless it also has a signaling system that lets it recognize fellow altruists (initially, close relatives) and a further mutation that places the altruistic behavior under the control of the receiver part of this system. Thus, altruists would only be altruistic to their own kind, the requirement for altruism to be selected in the presence of selfishness. Finally, the various parts of this system must be indissolubly linked in a way that the non-altruists cannot fake.

My solution is to label the crossing-over events that occur during meiosis as "tetra-mutations." In crossing over, two homologous chromosomes pair up along their length and swap a long segment of DNA, a process requiring four double chain breaks and their corresponding repairs. Because of the presence of single-nucleotide polymorphisms, the homologous chromosomes are not exactly the same, so that each of the upstream sides of the four chain breaks ends up in a subtly different genetic environment. If the break point falls between a cis-acting regulatory element and the corresponding structural gene, for instance, the former may now control the expression of a slightly different protein. Thus, there could be as many as four distinct functional consequences of one crossing-over event. Why not call that a tetra-mutation?

In this way, a concerted change affecting four distinct sites becomes possible. The two ends of the recombinant segment can in principle be functionally unrelated initially. They become related if both are affected by the same tetra-mutation and the entire change increases fitness and is thus selected.

A single tetra-mutation could in principle produce viable altruism at one stroke because of the number of simultaneous changes involved. 

The probability of a combination of simultaneous local changes being beneficial to the organism is much smaller on mathematical grounds than is the probability of a given single-nucleotide change being beneficial. However, these unfavorable statistics are at least partly offset by the existence of a dedicated system for producing tetra-mutations in large numbers, namely meiosis, part of the process of maturation of egg cells and sperm cells.

In the big picture, tetra-mutations provide a way for a species to discontinuously jump into new niches as they open up, possibly explaining how a capacity for this kind of mutation could spread and become characteristic of surviving species over time. This idea also provides a ready explanation for the lack of transitional forms in the fossil record.

5-30-2018: Here is the search description again, in case you missed it or could not see all of it: Sexual reproduction may allow the evolution of irreducible complexity by increasing the intrinsic complexity of the basic building block of change, the mutation.

6-12-2018: Upon further reflection, it seems that the tetramutation construct described above lacks validity because during gamete maturation it falls apart into two bi-mutations, both of which cannot contribute to the same zygote. The bi-mutation is stable, however, because of the intervening translocated DNA segment. It is harder to see how a complex adaptation like altruism could evolve out of nothing but mono-mutations and bi-mutations, but that does not mean the theory put forward in this post is necessarily wrong. One must not argue from lack of imagination. It is an interesting question, actually, what is the minimum set of all mutation types necessary to account for all known adaptations.

8-27-2019: In my ignorance, I have undersold the bi-mutation idea. A very far-reaching change to the genetic information can occur during crossing-over that is not at all subtle and is termed unequal crossing-over. This form of the process arises because of inaccuracies, sometimes major, in the initial alignment of the homologous chromosomes prior to crossing-over. When the process is finished, one chromosome has been shortened and the other has been lengthened, with gene duplication. This is the major source of gene duplication, which, in turn, is a major source of junk DNA, the part that is classified as broken genes. Two questions come to mind. The first is, are anatomical features such as jaw length and axon targets somehow controlled by variations in gene dose? The second, which is a tangent, is, are broken genes really broken or just temporarily switched off by genetic drift at some mutational hot spot in the recognition site of some transcription factor? The analogy here is to a generator in a power plant that has been placed in stand-down mode because of a temporary decrease in the demand for electrical power.

#38. The Fallacy of Justice [evolutionary psychology]

Red, theory; black, fact.

4-04-2018: In my treatment of evil and criminality so far, I have tried to show that they 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, with probably a large component coming from a hypothetical, fast form of evolution I call post-zygotic gamete selection (PGS), where gametes -- individual cells -- are effectively the units of selection. In general, the smaller the unit of selection, the faster the adaptation. PGS may have accelerated evolution to the point where it could be detected by simple record-keeping technologies, which may have led to the first record-keeping peoples eventually realizing that "someone is looking out for us," leading to the invention of monotheism.

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?"

I'm not so sure. 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.

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.

4-30-2018: 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. However, I originally wrote as I did because I don't think that the former is the squeaky wheel at the moment.

#37. Two Kinds of War [evolutionary psychology, engineering, neuroscience]

EN     EP     NE     
Red, theory; black, fact.

3-17-2018: In my post "The Pilgrim and the Whale", I propose that much human conflict sub serves dispersal.

12-28-2017: There are probably two basic biological uses for human anger, the other one being an emergency brake on population increase that avoids Malthusian disasters by triggering wars. This kind of war ends life without being notably efficient in producing mass migration. This is the use discussed in my post "The Iatrogenic Conflicts of the Twentieth Century." Mention of the destruction of Coventry was struck out because it looks better suited to population reduction than to triggering mass migration.

3-12-2018: I have long wondered why the Four Horsemen of the Apocalypse seem to include two gentlemen both in charge of warlike matters. Why the apparent duplication? The above postscript may give the reason: one (the guy with the bow) represents wars of (absolute) depopulation and the other (the guy with the sword) represents wars of displacement (relative depopulation).

The Coventry Blitz did, however, produce so much mass migration into the countryside surrounding that city that it was an embarrassment for the British government, calling into question Britain’s willingness to fight. This got me thinking: was Coventry some kind of watershed, before which the conflict was of the displacement type, and afterward, of the depopulation type?

The facts bear this out, considering Nazi treatment of the Jews as a litmus test of the zeitgeist of that time. After coming to power in 1933, the Nazis aimed at forcing the Jews to emigrate, and by the outbreak of hostilities in September, 1939, 250,000 of Germany’s 437,000 Jews had done so. The Coventry Blitz was in November, 1940. The Holocaust began, in terms of men, women, and children all being targeted for execution, in August, 1941, nine months later. The German zeitgeist, and perhaps that of the world, seems to have shifted gears in the fall of 1940, aiming at depopulation rather than displacement. I am obviously assuming that the evolutionary, selectionist justification of the Holocaust given at the time, in forums such as the 1942 Wannsee conference, was a rationalization.

I conjecture that wars brought on by population pressure begin as the displacement type, and if this does not result in sufficient local reduction in population pressure after a certain time, the hostilities shift gears to the depopulation type of conflict. If human population is under PID [proportional-integral-differential] control by the subconscious, the event causing the shift could be the amount of signal accumulated on the integrator rising above some threshold. This may actually be a second threshold, with the first and lower threshold controlling the outbreak of a war of displacement.

A paradoxical outcome of Calhoun's overpopulation experiments on rodents can be explained in terms of such an integrator. By providing unlimited food and water to a founder population of rats or mice, with regular bedding changes and exclusion of predators and parasites, the rodents were allowed to increase their population to fabulous numbers. However, the rodents were given no extra space. As the population soared to incredible densities, all kinds of pathological behaviors appeared along with a great deal of violence. Birth rates plummeted after a "behavioral sink" developed, and remained low, never recovering, as the population decreased all the way to zero.

My interpretation of the behavioral sink is that it is integrator windup, a pathology of humanly engineered PID controllers, and possibly natural ones too. The signal accumulated on the integrator has been building for so long, and the population crash is so sudden, that not enough time is spent at population densities below set point to cancel the "control debt" on the integrator, so it continues to insanely command a zero birth rate even as the population is heading for zero.

George Santayana wrote that "Fanaticism consists of redoubling your efforts when you have forgotten your aim." [source, Wiki quotes, accessed 06-11-2018] Sounds like integrator windup to me.

3-17-2018: To clean up some loose ends, let us postulate a third and highest threshold of the control debt, which, if crossed, leads to the human behavioral sink and the possible destruction of the human race due to essentially psychological causes. In the behavioral sink, I postulate that everyone would be a ZPG fanatic and unable to change without pharmacological help. (Good old booze? May not be that simple.) 

I myself may be a "ZPG fanatic", and produced in exactly this way, because I was born in 1953, just before suburbia became important, and may represent what most people in this country would now be had suburbia not been invented to take down the population pressure. At only 2 months from retirement age, I continue to be a virgin with no plans to change my ways, and I may be a straw in the wind, a harbinger of worse to come.

11-26-2019: I can testify from my own experience that the human behavioral sink is more like passive-aggressive personality disorder than anything else, but with particular attention to punishing the opposite sex by ignoring them.

3-22-2018: Correction: the modern suburbs were invented in London 200 years ago, but underwent explosive growth in North America after WWII. By 1950, half the American population was suburban.

#36. The Thought Process Through the Ages [evolutionary psychology]

Red, theory; black, fact.

2-01-2018: An alternative title of this post could be: "Where religion possibly fits in the big scheme of things."

If politics and science seem like strange bedfellows, consider that ancient rulers used to consult astrologers before making major decisions.

In the beginning, there was theology. At some point, intellectual endeavor split into wrestling with reality questions vs. morality questions. Then they had to figure out when to go with your gut and when not to.

2-23-2018: Just as emotion must not be allowed to contaminate scientific thought, is it equally true that reason must not be allowed to contaminate religious thought? Is failure to observe this restriction the cause of religious schisms?

08-03-2019: Thought-like processes dominated by emotion are believed to exist, e.g., the "emotional processing" of traumatic memories.
