Is there a common method for detecting the convergence of the Gibbs sampler and the expectation-maximization algorithm? - Quora
In practice and theory it is much easier to diagnose convergence in EM (vanilla or variational) than in any MCMC algorithm (including Gibbs sampling).

https://www.quora.com/How-can-you-determine-if-your-Gibbs-sampler-has-converged
There is a special case when you can actually obtain the stationary distribution, and be sure that you did! If your markov chain consists of a discrete state space, then take the first time that a state repeats in your chain: if you randomly sample an element between the repeating states (but only including one of the endpoints) you will have a sample from your true distribution.

One can achieve this 'exact MCMC sampling' more generally by using the coupling from the past algorithm (Coupling from the past).

Otherwise, there is no rigorous statistical test for convergence. It may be possible to obtain a theoretical bound for the convergence rates: but these are quite difficult to obtain, and quite often too large to be of practical use. For example, even for the simple case of using the Metropolis algorithm for sampling from a two-dimensional uniform distribution, the best convergence rate upper bound achieved, by Persi Diaconis, was something with an astronomical constant factor like 10^300.

In fact, it is fair to say that for most high dimensional problems, we have really no idea whether Gibbs sampling ever comes close to converging, but the best we can do is use some simple diagnostics to detect the most obvious failures.

Should I go for TensorFlow or PyTorch?
Honestly, most experts that I know love Pytorch and detest TensorFlow. Karpathy and Justin from Stanford for example. You can see Karpthy's thoughts and I've asked Justin personally and the answer was sharp: PYTORCH!!! TF has lots of PR but its API and graph model are horrible and will waste lots of your research time.

Updated Mar 12
Update after 2019 TF summit:

TL/DR: previously I was in the pytorch camp but with TF 2.0 it’s clear that Google is really going to try to have parity or try to be better than Pytorch in all aspects where people voiced concerns (ease of use/debugging/dynamic graphs). They seem to be allocating more resources on development than Facebook so the longer term currently looks promising for Google. Prior to TF 2.0 I thought that Pytorch team had more momentum. One area where FB/Pytorch is still stronger is Google is a bit more closed and doesn’t seem to release reproducible cutting edge models such as AlphaGo whereas FAIR released OpenGo for instance. Generally you will end up running into models that are only implemented in one framework of the other so chances are you might end up learning both.

Lateralization of brain function - Wikipedia
Language
Language functions such as grammar, vocabulary and literal meaning are typically lateralized to the left hemisphere, especially in right handed individuals.[3] While language production is left-lateralized in up to 90% of right-handers, it is more bilateral, or even right-lateralized, in approximately 50% of left-handers.[4]

Broca's area and Wernicke's area, two areas associated with the production of speech, are located in the left cerebral hemisphere for about 95% of right-handers, but about 70% of left-handers.[5]:69

Auditory and visual processing
The processing of visual and auditory stimuli, spatial manipulation, facial perception, and artistic ability are represented bilaterally.[4] Numerical estimation, comparison and online calculation depend on bilateral parietal regions[6][7] while exact calculation and fact retrieval are associated with left parietal regions, perhaps due to their ties to linguistic processing.[6][7]

...

Depression is linked with a hyperactive right hemisphere, with evidence of selective involvement in "processing negative emotions, pessimistic thoughts and unconstructive thinking styles", as well as vigilance, arousal and self-reflection, and a relatively hypoactive left hemisphere, "specifically involved in processing pleasurable experiences" and "relatively more involved in decision-making processes".

Chaos and Order; the right and left hemispheres: https://orthosphere.wordpress.com/2018/05/23/chaos-and-order-the-right-and-left-hemispheres/
In The Master and His Emissary, Iain McGilchrist writes that a creature like a bird needs two types of consciousness simultaneously. It needs to be able to focus on something specific, such as pecking at food, while it also needs to keep an eye out for predators which requires a more general awareness of environment.

These are quite different activities. The Left Hemisphere (LH) is adapted for a narrow focus. The Right Hemisphere (RH) for the broad. The brains of human beings have the same division of function.

The LH governs the right side of the body, the RH, the left side. With birds, the left eye (RH) looks for predators, the right eye (LH) focuses on food and specifics. Since danger can take many forms and is unpredictable, the RH has to be very open-minded.

The LH is for narrow focus, the explicit, the familiar, the literal, tools, mechanism/machines and the man-made. The broad focus of the RH is necessarily more vague and intuitive and handles the anomalous, novel, metaphorical, the living and organic. The LH is high resolution but narrow, the RH low resolution but broad.

The LH exhibits unrealistic optimism and self-belief. The RH has a tendency towards depression and is much more realistic about a person’s own abilities. LH has trouble following narratives because it has a poor sense of “wholes.” In art it favors flatness, abstract and conceptual art, black and white rather than color, simple geometric shapes and multiple perspectives all shoved together, e.g., cubism. Particularly RH paintings emphasize vistas with great depth of field and thus space and time,[1] emotion, figurative painting and scenes related to the life world. In music, LH likes simple, repetitive rhythms. The RH favors melody, harmony and complex rhythms.

...

Schizophrenia is a disease of extreme LH emphasis. Since empathy is RH and the ability to notice emotional nuance facially, vocally and bodily expressed, schizophrenics tend to be paranoid and are often convinced that the real people they know have been replaced by robotic imposters. This is at least partly because they lose the ability to intuit what other people are thinking and feeling – hence they seem robotic and suspicious.

Oswald Spengler’s The Decline of the West as well as McGilchrist characterize the West as awash in phenomena associated with an extreme LH emphasis. Spengler argues that Western civilization was originally much more RH (to use McGilchrist’s categories) and that all its most significant artistic (in the broadest sense) achievements were triumphs of RH accentuation.

The RH is where novel experiences and the anomalous are processed and where mathematical, and other, problems are solved. The RH is involved with the natural, the unfamiliar, the unique, emotions, the embodied, music, humor, understanding intonation and emotional nuance of speech, the metaphorical, nuance, and social relations. It has very little speech, but the RH is necessary for processing all the nonlinguistic aspects of speaking, including body language. Understanding what someone means by vocal inflection and facial expressions is an intuitive RH process rather than explicit.

...

RH is very much the center of lived experience; of the life world with all its depth and richness. The RH is “the master” from the title of McGilchrist’s book. The LH ought to be no more than the emissary; the valued servant of the RH. However, in the last few centuries, the LH, which has tyrannical tendencies, has tried to become the master. The LH is where the ego is predominantly located. In split brain patients where the LH and the RH are surgically divided (this is done sometimes in the case of epileptic patients) one hand will sometimes fight with the other. In one man’s case, one hand would reach out to hug his wife while the other pushed her away. One hand reached for one shirt, the other another shirt. Or a patient will be driving a car and one hand will try to turn the steering wheel in the opposite direction. In these cases, the “naughty” hand is usually the left hand (RH), while the patient tends to identify herself with the right hand governed by the LH. The two hemispheres have quite different personalities.

The connection between LH and ego can also be seen in the fact that the LH is competitive, contentious, and agonistic. It wants to win. It is the part of you that hates to lose arguments.

Using the metaphor of Chaos and Order, the RH deals with Chaos – the unknown, the unfamiliar, the implicit, the emotional, the dark, danger, mystery. The LH is connected with Order – the known, the familiar, the rule-driven, the explicit, and light of day. Learning something means to take something unfamiliar and making it familiar. Since the RH deals with the novel, it is the problem-solving part. Once understood, the results are dealt with by the LH. When learning a new piece on the piano, the RH is involved. Once mastered, the result becomes a LH affair. The muscle memory developed by repetition is processed by the LH. If errors are made, the activity returns to the RH to figure out what went wrong; the activity is repeated until the correct muscle memory is developed in which case it becomes part of the familiar LH.

Science is an attempt to find Order. It would not be necessary if people lived in an entirely orderly, explicit, known world. The lived context of science implies Chaos. Theories are reductive and simplifying and help to pick out salient features of a phenomenon. They are always partial truths, though some are more partial than others. The alternative to a certain level of reductionism or partialness would be to simply reproduce the world which of course would be both impossible and unproductive. The test for whether a theory is sufficiently non-partial is whether it is fit for purpose and whether it contributes to human flourishing.

...

Analytic philosophers pride themselves on trying to do away with vagueness. To do so, they tend to jettison context which cannot be brought into fine focus. However, in order to understand things and discern their meaning, it is necessary to have the big picture, the overview, as well as the details. There is no point in having details if the subject does not know what they are details of. Such philosophers also tend to leave themselves out of the picture even when what they are thinking about has reflexive implications. John Locke, for instance, tried to banish the RH from reality. All phenomena having to do with subjective experience he deemed unreal and once remarked about metaphors, a RH phenomenon, that they are “perfect cheats.” Analytic philosophers tend to check the logic of the words on the page and not to think about what those words might say about them. The trick is for them to recognize that they and their theories, which exist in minds, are part of reality too.

The RH test for whether someone actually believes something can be found by examining his actions. If he finds that he must regard his own actions as free, and, in order to get along with other people, must also attribute free will to them and treat them as free agents, then he effectively believes in free will – no matter his LH theoretical commitments.

...

We do not know the origin of life. We do not know how or even if consciousness can emerge from matter. We do not know the nature of 96% of the matter of the universe. Clearly all these things exist. They can provide the subject matter of theories but they continue to exist as theorizing ceases or theories change. Not knowing how something is possible is irrelevant to its actual existence. An inability to explain something is ultimately neither here nor there.

If thought begins and ends with the LH, then thinking has no content – content being provided by experience (RH), and skepticism and nihilism ensue. The LH spins its wheels self-referentially, never referring back to experience. Theory assumes such primacy that it will simply outlaw experiences and data inconsistent with it; a profoundly wrong-headed approach.

...

Gödel’s Theorem proves that not everything true can be proven to be true. This means there is an ineradicable role for faith, hope and intuition in every moderately complex human intellectual endeavor. There is no one set of consistent axioms from which all other truths can be derived.

Alan Turing’s proof of the halting problem proves that there is no effective procedure for finding effective procedures. Without a mechanical decision procedure, (LH), when it comes to … [more]

Eliminative materialism - Wikipedia
Eliminative materialism (also called eliminativism) is the claim that people's common-sense understanding of the mind (or folk psychology) is false and that certain classes of mental states that most people believe in do not exist.[1] It is a materialist position in the philosophy of mind. Some supporters of eliminativism argue that no coherent neural basis will be found for many everyday psychological concepts such as belief or desire, since they are poorly defined. Rather, they argue that psychological concepts of behaviour and experience should be judged by how well they reduce to the biological level.[2] Other versions entail the non-existence of conscious mental states such as pain and visual perceptions.[3]

Eliminativism about a class of entities is the view that that class of entities does not exist.[4] For example, materialism tends to be eliminativist about the soul; modern chemists are eliminativist about phlogiston; and modern physicists are eliminativist about the existence of luminiferous aether. Eliminative materialism is the relatively new (1960s–1970s) idea that certain classes of mental entities that common sense takes for granted, such as beliefs, desires, and the subjective sensation of pain, do not exist.[5][6] The most common versions are eliminativism about propositional attitudes, as expressed by Paul and Patricia Churchland,[7] and eliminativism about qualia (subjective interpretations about particular instances of subjective experience), as expressed by Daniel Dennett and Georges Rey.[3] These philosophers often appeal to an introspection illusion.

In the context of materialist understandings of psychology, eliminativism stands in opposition to reductive materialism which argues that mental states as conventionally understood do exist, and that they directly correspond to the physical state of the nervous system.[8][need quotation to verify] An intermediate position is revisionary materialism, which will often argue that the mental state in question will prove to be somewhat reducible to physical phenomena—with some changes needed to the common sense concept.

Since eliminative materialism claims that future research will fail to find a neuronal basis for various mental phenomena, it must necessarily wait for science to progress further. One might question the position on these grounds, but other philosophers like Churchland argue that eliminativism is often necessary in order to open the minds of thinkers to new evidence and better explanations.[8]

Christian ethics - Wikipedia
Christian ethics is a branch of Christian theology that defines virtuous behavior and wrong behavior from a Christian perspective. Systematic theological study of Christian ethics is called moral theology, possibly with the name of the respective theological tradition, e.g. Catholic moral theology.

Christian virtues are often divided into four cardinal virtues and three theological virtues. Christian ethics includes questions regarding how the rich should act toward the poor, how women are to be treated, and the morality of war. Christian ethicists, like other ethicists, approach ethics from different frameworks and perspectives. The approach of virtue ethics has also become popular in recent decades, largely due to the work of Alasdair MacIntyre and Stanley Hauerwas.[2]

...

The seven Christian virtues are from two sets of virtues. The four cardinal virtues are Prudence, Justice, Restraint (or Temperance), and Courage (or Fortitude). The cardinal virtues are so called because they are regarded as the basic virtues required for a virtuous life. The three theological virtues, are Faith, Hope, and Love (or Charity).

- Prudence: also described as wisdom, the ability to judge between actions with regard to appropriate actions at a given time
- Justice: also considered as fairness, the most extensive and most important virtue[20]
- Temperance: also known as restraint, the practice of self-control, abstention, and moderation tempering the appetition
- Courage: also termed fortitude, forebearance, strength, endurance, and the ability to confront fear, uncertainty, and intimidation
- Faith: belief in God, and in the truth of His revelation as well as obedience to Him (cf. Rom 1:5:16:26)[21][22]
- Hope: expectation of and desire of receiving; refraining from despair and capability of not giving up. The belief that God will be eternally present in every human's life and never giving up on His love.
- Charity: a supernatural virtue that helps us love God and our neighbors, the same way as we love ourselves.

The seven deadly sins, also known as the capital vices or cardinal sins, is a grouping and classification of vices of Christian origin.[1] Behaviours or habits are classified under this category if they directly give birth to other immoralities.[2] According to the standard list, they are pride, greed, lust, envy, gluttony, wrath, and sloth,[2] which are also contrary to the seven virtues. These sins are often thought to be abuses or excessive versions of one's natural faculties or passions (for example, gluttony abuses one's desire to eat).

originally:
1 Gula (gluttony)
2 Luxuria/Fornicatio (lust, fornication)
3 Avaritia (avarice/greed)
4 Superbia (pride, hubris)
5 Tristitia (sorrow/despair/despondency)
6 Ira (wrath)
7 Vanagloria (vainglory)
8 Acedia (sloth)

Golden Rule: https://en.wikipedia.org/wiki/Golden_Rule
The Golden Rule (which can be considered a law of reciprocity in some religions) is the principle of treating others as one would wish to be treated. It is a maxim that is found in many religions and cultures.[1][2] The maxim may appear as _either a positive or negative injunction_ governing conduct:

- One should treat others as one would like others to treat oneself (positive or directive form).[1]
- One should not treat others in ways that one would not like to be treated (negative or prohibitive form).[1]
- What you wish upon others, you wish upon yourself (empathic or responsive form).[1]
The Golden Rule _differs from the maxim of reciprocity captured in do ut des—"I give so that you will give in return"—and is rather a unilateral moral commitment to the well-being of the other without the expectation of anything in return_.[3]

The concept occurs in some form in nearly every religion[4][5] and ethical tradition[6] and is often considered _the central tenet of Christian ethics_[7] [8]. It can also be explained from the perspectives of psychology, philosophy, sociology, human evolution, and economics. Psychologically, it involves a person empathizing with others. Philosophically, it involves a person perceiving their neighbor also as "I" or "self".[9] Sociologically, "love your neighbor as yourself" is applicable between individuals, between groups, and also between individuals and groups. In evolution, "reciprocal altruism" is seen as a distinctive advance in the capacity of human groups to survive and reproduce, as their exceptional brains demanded exceptionally long childhoods and ongoing provision and protection even beyond that of the immediate family.[10] In economics, Richard Swift, referring to ideas from David Graeber, suggests that "without some kind of reciprocity society would no longer be able to exist."[11]

...

Seneca the Younger (c. 4 BC–65 AD), a practitioner of Stoicism (c. 300 BC–200 AD) expressed the Golden Rule in his essay regarding the treatment of slaves: "Treat your inferior as you would wish your superior to treat you."[23]

...

The "Golden Rule" was given by Jesus of Nazareth, who used it to summarize the Torah: "Do to others what you want them to do to you." and "This is the meaning of the law of Moses and the teaching of the prophets"[33] (Matthew 7:12 NCV, see also Luke 6:31). The common English phrasing is "Do unto others as you would have them do unto you". A similar form of the phrase appeared in a Catholic catechism around 1567 (certainly in the reprint of 1583).[34] The Golden Rule is _stated positively numerous times in the Hebrew Pentateuch_ as well as the Prophets and Writings. Leviticus 19:18 ("Forget about the wrong things people do to you, and do not try to get even. Love your neighbor as you love yourself."; see also Great Commandment) and Leviticus 19:34 ("But treat them just as you treat your own citizens. Love foreigners as you love yourselves, because you were foreigners one time in Egypt. I am the Lord your God.").

The Old Testament Deuterocanonical books of Tobit and Sirach, accepted as part of the Scriptural canon by Catholic Church, Eastern Orthodoxy, and the Non-Chalcedonian Churches, express a _negative form_ of the golden rule:

"Do to no one what you yourself dislike."

— Tobit 4:15
"Recognize that your neighbor feels as you do, and keep in mind your own dislikes."

— Sirach 31:15
Two passages in the New Testament quote Jesus of Nazareth espousing the _positive form_ of the Golden rule:

Matthew 7:12
Do to others what you want them to do to you. This is the meaning of the law of Moses and the teaching of the prophets.

Luke 6:31
Do to others what you would want them to do to you.

...

The passage in the book of Luke then continues with Jesus answering the question, "Who is my neighbor?", by telling the parable of the Good Samaritan, indicating that "your neighbor" is anyone in need.[35] This extends to all, including those who are generally considered hostile.

Jesus' teaching goes beyond the negative formulation of not doing what one would not like done to themselves, to the positive formulation of actively doing good to another that, if the situations were reversed, one would desire that the other would do for them. This formulation, as indicated in the parable of the Good Samaritan, emphasizes the needs for positive action that brings benefit to another, not simply restraining oneself from negative activities that hurt another. Taken as a rule of judgment, both formulations of the golden rule, the negative and positive, are equally applicable.[36]

The Golden Rule: Not So Golden Anymore: https://philosophynow.org/issues/74/The_Golden_Rule_Not_So_Golden_Anymore
Pluralism is the most serious problem facing liberal democracies today. We can no longer ignore the fact that cultures around the world are not simply different from one another, but profoundly so; and the most urgent area in which this realization faces us is in the realm of morality. Western democratic systems depend on there being at least a minimal consensus concerning national values, especially in regard to such things as justice, equality and human rights. But global communication, economics and the migration of populations have placed new strains on Western democracies. Suddenly we find we must adjust to peoples whose suppositions about the ultimate values and goals of life are very different from ours. A clear lesson from events such as 9/11 is that disregarding these differences is not an option. Collisions between worldviews and value systems can be cataclysmic. Somehow we must learn to manage this new situation.

For a long time, liberal democratic optimism in the West has been shored up by suppositions about other cultures and their differences from us. The cornerpiece of this optimism has been the assumption that whatever differences exist they cannot be too great. A core of ‘basic humanity’ surely must tie all of the world’s moral systems together – and if only we could locate this core we might be able to forge agreements and alliances among groups that otherwise appear profoundly opposed. We could perhaps then shelve our cultural or ideological differences and get on with the more pleasant and productive business of celebrating our core agreement. One cannot fail to see how this hope is repeated in order buoy optimism about the Middle East peace process, for example.

...

It becomes obvious immediately that no matter how widespread we want the Golden Rule to be, there are some ethical systems that we have to admit do not have it. In fact, there are a few traditions that actually disdain the Rule. In philosophy, the Nietzschean tradition holds that the virtues implicit in the Golden Rule are antithetical to the true virtues of self-assertion and the will-to-power. Among religions, there are a good many that prefer to emphasize the importance of self, cult, clan or tribe rather than of general others; and a good many other religions for whom large populations are simply excluded from goodwill, being labeled as outsiders, heretics or … [more]

Prisoner's dilemma - Wikipedia
caveat to result below:
An extension of the IPD is an evolutionary stochastic IPD, in which the relative abundance of particular strategies is allowed to change, with more successful strategies relatively increasing. This process may be accomplished by having less successful players imitate the more successful strategies, or by eliminating less successful players from the game, while multiplying the more successful ones. It has been shown that unfair ZD strategies are not evolutionarily stable. The key intuition is that an evolutionarily stable strategy must not only be able to invade another population (which extortionary ZD strategies can do) but must also perform well against other players of the same type (which extortionary ZD players do poorly, because they reduce each other's surplus).[14]

Theory and simulations confirm that beyond a critical population size, ZD extortion loses out in evolutionary competition against more cooperative strategies, and as a result, the average payoff in the population increases when the population is bigger. In addition, there are some cases in which extortioners may even catalyze cooperation by helping to break out of a face-off between uniform defectors and win–stay, lose–switch agents.[8]

https://alfanl.com/2018/04/12/defection/
Nature boils down to a few simple concepts.

Haters will point out that I oversimplify. The haters are wrong. I am good at saying a lot with few words. Nature indeed boils down to a few simple concepts.

In life, you can either cooperate or defect.

Used to be that defection was the dominant strategy, say in the time when the Roman empire started to crumble. Everybody complained about everybody and in the end nothing got done. Then came Jesus, who told people to be loving and cooperative, and boom: 1800 years later we get the industrial revolution.

Because of Jesus we now find ourselves in a situation where cooperation is the dominant strategy. A normie engages in a ton of cooperation: with the tax collector who wants more and more of his money, with schools who want more and more of his kid’s time, with media who wants him to repeat more and more party lines, with the Zeitgeist of the Collective Spirit of the People’s Progress Towards a New Utopia. Essentially, our normie is cooperating himself into a crumbling Western empire.

Turns out that if everyone blindly cooperates, parasites sprout up like weeds until defection once again becomes the standard.

The point of a post-Christian religion is to once again create conditions for the kind of cooperation that led to the industrial revolution. This necessitates throwing out undead Christianity: you do not blindly cooperate. You cooperate with people that cooperate with you, you defect on people that defect on you. Christianity mixed with Darwinism. God and Gnon meet.

This also means we re-establish spiritual hierarchy, which, like regular hierarchy, is a prerequisite for cooperation. It is this hierarchical cooperation that turns a household into a force to be reckoned with, that allows a group of men to unite as a front against their enemies, that allows a tribe to conquer the world. Remember: Scientology bullied the Cathedral’s tax department into submission.

With a functioning hierarchy, men still gossip, lie and scheme, but they will do so in whispers behind closed doors. In your face they cooperate and contribute to the group’s wellbeing because incentives are thus that contributing to group wellbeing heightens status.

Without a functioning hierarchy, men gossip, lie and scheme, but they do so in your face, and they tell you that you are positively deluded for accusing them of gossiping, lying and scheming. Seeds will not sprout in such ground.

Spiritual dominance is established in the same way any sort of dominance is established: fought for, taken. But the fight is ritualistic. You can’t force spiritual dominance if no one listens, or if you are silenced the ritual is not allowed to happen.

If one of our priests is forbidden from establishing spiritual dominance, that is a sure sign an enemy priest is in better control and has vested interest in preventing you from establishing spiritual dominance..

They defect on you, you defect on them. Let them suffer the consequences of enemy priesthood, among others characterized by the annoying tendency that very little is said with very many words.

https://contingentnotarbitrary.com/2018/04/14/rederiving-christianity/
To recap, we started with a secular definition of Logos and noted that its telos is existence. Given human nature, game theory and the power of cooperation, the highest expression of that telos is freely chosen universal love, tempered by constant vigilance against defection while maintaining compassion for the defectors and forgiving those who repent. In addition, we must know the telos in order to fulfill it.

In Christian terms, looks like we got over half of the Ten Commandments (know Logos for the First, don’t defect or tempt yourself to defect for the rest), the importance of free will, the indestructibility of evil (group cooperation vs individual defection), loving the sinner and hating the sin (with defection as the sin), forgiveness (with conditions), and love and compassion toward all, assuming only secular knowledge and that it’s good to exist.

Iterated Prisoner's Dilemma is an Ultimatum Game: http://infoproc.blogspot.com/2012/07/iterated-prisoners-dilemma-is-ultimatum.html
The history of IPD shows that bounded cognition prevented the dominant strategies from being discovered for over over 60 years, despite significant attention from game theorists, computer scientists, economists, evolutionary biologists, etc. Press and Dyson have shown that IPD is effectively an ultimatum game, which is very different from the Tit for Tat stories told by generations of people who worked on IPD (Axelrod, Dawkins, etc., etc.).

...

For evolutionary biologists: Dyson clearly thinks this result has implications for multilevel (group vs individual selection):
... Cooperation loses and defection wins. The ZD strategies confirm this conclusion and make it sharper. ... The system evolved to give cooperative tribes an advantage over non-cooperative tribes, using punishment to give cooperation an evolutionary advantage within the tribe. This double selection of tribes and individuals goes way beyond the Prisoners' Dilemma model.

implications for fractionalized Europe vis-a-vis unified China?

and more broadly does this just imply we're doomed in the long run RE: cooperation, morality, the "good society", so on...? war and group-selection is the only way to get a non-crab bucket civilization?

The nature of human altruism: http://sci-hub.tw/https://www.nature.com/articles/nature02043
- Ernst Fehr & Urs Fischbacher

Some of the most fundamental questions concerning our evolutionary origins, our social relations, and the organization of society are centred around issues of altruism and selfishness. Experimental evidence indicates that human altruism is a powerful force and is unique in the animal world. However, there is much individual heterogeneity and the interaction between altruists and selfish individuals is vital to human cooperation. Depending on the environment, a minority of altruists can force a majority of selfish individuals to cooperate or, conversely, a few egoists can induce a large number of altruists to defect. Current gene-based evolutionary theories cannot explain important patterns of human altruism, pointing towards the importance of both theories of cultural evolution as well as gene–culture co-evolution.

...

Why are humans so unusual among animals in this respect? We propose that quantitatively, and probably even qualitatively, unique patterns of human altruism provide the answer to this question. Human altruism goes far beyond that which has been observed in the animal world. Among animals, fitness-reducing acts that confer fitness benefits on other individuals are largely restricted to kin groups; despite several decades of research, evidence for reciprocal altruism in pair-wise repeated encounters4,5 remains scarce6–8. Likewise, there is little evidence so far that individual reputation building affects cooperation in animals, which contrasts strongly with what we find in humans. If we randomly pick two human strangers from a modern society and give them the chance to engage in repeated anonymous exchanges in a laboratory experiment, there is a high probability that reciprocally altruistic behaviour will emerge spontaneously9,10.

However, human altruism extends far beyond reciprocal altruism and reputation-based cooperation, taking the form of strong reciprocity11,12. Strong reciprocity is a combination of altruistic rewarding, which is a predisposition to reward others for cooperative, norm-abiding behaviours, and altruistic punishment, which is a propensity to impose sanctions on others for norm violations. Strong reciprocators bear the cost of rewarding or punishing even if they gain no individual economic benefit whatsoever from their acts. In contrast, reciprocal altruists, as they have been defined in the biological literature4,5, reward and punish only if this is in their long-term self-interest. Strong reciprocity thus constitutes a powerful incentive for cooperation even in non-repeated interactions and when reputation gains are absent, because strong reciprocators will reward those who cooperate and punish those who defect.

...

We will show that the interaction between selfish and strongly reciprocal … [more]

Second Bananas | West Hunter
Still thinking about domestication. Mostly,  the wild ancestors of domesticate animals were social: presumably, such behavioral tendencies were preadaptations that helped the domesticates come to bond with or at least tolerate people.   Social animals can have adaptive personality variation – difference behavioral strategies.  Sometimes those strategies are facultative, sometimes genetic, sometimes a mix.

I would guess that those wild individuals that account for most of the ancestry of f a domesticated species didn’t have a representative mix of personality types. Probably they were more likely to be followers rather than leaders – not the alphas of the pack, not the most aggressive stallions.  Sidekicks.  With dogs, we can probably check this hypothesis fairly easily, since wolves are still around.

https://westhunt.wordpress.com/2013/04/03/wyld-stallyns/
A few years ago, I was thinking about genetic male morphs. Turns out that you find qualitatively different forms of males in many species: Barry Sinervos’s lizards, Shuster’s isopods, Lank’s ruffs, jack salmon, etc. Logically, the Y chromosome would be the best place for a such a genetic switch, since that would avoid negative side effects in females. The problem is that the Y carries very few genes.

Alternate strategies don’t have to to be as complicated as they are in ruffs or Uta stansburiana. Different levels of aggressiveness, or different points on the cad/dad axis, would have different selective payoffs in different environments. If a new environment favored lower (or higher) aggressiveness in males , a Y-chromosome that induced lower (or higher) aggressiveness would take off. And since different Y chromosomes do indeed affect the level of aggressiveness in mice [which I just found out], possibly by affecting testosterone production – this mechanism is plausible.

This could explain a funny genetic pattern in the domestication of horses. There’s a fair amount of diversity in horse mtDNA: it looks as if many different mares were domesticated. On the other hand, it looks as if only one stallion was ever domesticated. All living stallions today are his descendants.

Stallions are pretty aggressive, and must have been hard to tame. Maybe one was genetically unusual – wimpier. Tameable.

Fortunately for all concerned, the selective value of aggressiveness, etc. has been the same for all human populations forever and ever, before and after the development of agriculture. Otherwise you might see weirdly rapid expansions of particular Y-chromosome haplogroups – common, yet only a few thousand years old.

https://westhunt.wordpress.com/2018/04/18/wyld-stallyns-part-deux/
A while ago, I wondered if modern stallions are a male morph adapted to domestication, one in which the strategy is mediated via the Y chromosome.

Looks as if I was right*. Check out “Decline of genetic diversity in ancient domestic stallions in Europe”.

Selection favored one particular kind of Y-chromosome. This had to be based on phenotype, not genealogy. Most likely it was favored under the new environment of domestication. Somehow, these stallions performed better, or were easier to get along with (my bet).

We already knew that Y-chromosomes could do things: Haplogroup I increases the risk of heart disease by about 50%, while the particular variant of Y chromosome influences aggression in mice.

Which means you have to re-examine the starburst phylogeny of R1b and R1a: it’s probably biology, rather than history, that drove those expansions. Some kind of selective advantage. Possibly one reason that those particular Y chromosomes far outraced steppe autosomal contributions. Most likely, R1a and R1b induce specific morphs – their carriers are somehow different. Maybe they’re born to be mild, or born to be princes of the universe. Maybe an R1b guy just finds it easier to cooperate with other R1b guys… Or maybe they’re resistant to typhoid.

All models are wrong - Wikipedia
Box repeated the aphorism in a paper that was published in the proceedings of a 1978 statistics workshop.[2] The paper contains a section entitled "All models are wrong but some are useful". The section is copied below.

Now it would be very remarkable if any system existing in the real world could be exactly represented by any simple model. However, cunningly chosen parsimonious models often do provide remarkably useful approximations. For example, the law PV = RT relating pressure P, volume V and temperature T of an "ideal" gas via a constant R is not exactly true for any real gas, but it frequently provides a useful approximation and furthermore its structure is informative since it springs from a physical view of the behavior of gas molecules.

For such a model there is no need to ask the question "Is the model true?". If "truth" is to be the "whole truth" the answer must be "No". The only question of interest is "Is the model illuminating and useful?".

Alzheimers | West Hunter
Some disease syndromes almost have to be caused by pathogens – for example, any with a fitness impact (prevalence x fitness reduction) > 2% or so, too big to be caused by mutational pressure. I don’t think that this is the case for AD: it hits so late in life that the fitness impact is minimal. However, that hardly means that it can’t be caused by a pathogen or pathogens – a big fraction of all disease syndromes are, including many that strike in old age. That possibility is always worth checking out, not least because infectious diseases are generally easier to prevent and/or treat.

There is new work that strongly suggests that pathogens are the root cause. It appears that the amyloid is an antimicrobial peptide. amyloid-beta binds to invading microbes and then surrounds and entraps them. ‘When researchers injected Salmonella into mice’s hippocampi, a brain area damaged in Alzheimer’s, A-beta quickly sprang into action. It swarmed the bugs and formed aggregates called fibrils and plaques. “Overnight you see the plaques throughout the hippocampus where the bugs were, and then in each single plaque is a single bacterium,” Tanzi says. ‘

All too often we see large, long-lasting research efforts that never produce, never achieve their goal.

For example, the amyloid hypothesis [accumulation of amyloid-beta oligomers is the cause of Alzheimers] has been dominant for more than 20 years, and has driven development of something like 15 drugs. None of them have worked. At the same time the well-known increased risk from APOe4 has been almost entirely ignored, even though it ought to be a clue to the cause.

In general, when a research effort has been spinning its wheels for a generation or more, shouldn’t we try something different? We could at least try putting a fraction of those research dollars into alternative approaches that have not yet failed repeatedly.

Mostly this applies to research efforts that at least wish they were science. ‘educational research’ is in a special class, and I hardly know what to recommend. Most of the remedial actions that occur to me violate one or more of the Geneva conventions.

Look,if I could find out the sort of places that I usually misplace my keys – if I did, which I don’t – I could find the keys more easily the next time I lose them. If you find out that practitioners of a given field are not very competent, it marks that field as a likely place to look for relatively easy discovery. Thus medicine is a promising field, because on the whole doctors are not terribly good investigators. For example, none of the drugs developed for Alzheimers have worked at all, which suggests that our ideas on the causation of Alzheimers are likely wrong. Which suggests that it may (repeat may) be possible to make good progress on Alzheimers, either by an entirely empirical approach, which is way underrated nowadays, or by dumping the current explanation, finding a better one, and applying it.

You could start by looking at basic notions of field X and asking yourself: How do we really know that? Is there serious statistical evidence? Does that notion even accord with basic theory? This sort of checking is entirely possible. In most of the social sciences, we don’t, there isn’t, and it doesn’t.

Defection – quas lacrimas peperere minoribus nostris!
https://quaslacrimas.wordpress.com/2017/06/28/discussion-of-defection/

Kindness Against The Grain: https://srconstantin.wordpress.com/2017/06/08/kindness-against-the-grain/
I’ve heard from a number of secular-ish sources (Carse, Girard, Arendt) that the essential contribution of Christianity to human thought is the concept of forgiveness. (Ribbonfarm also has a recent post on the topic of forgiveness.)

I have never been a Christian and haven’t even read all of the New Testament, so I’ll leave it to commenters to recommend Christian sources on the topic.

What I want to explore is the notion of kindness without a smooth incentive gradient.

The Social Module: https://bloodyshovel.wordpress.com/2015/10/09/the-social-module/
Now one could propose that the basic principle of human behavior is to raise the SP number. Sure there’s survival and reproduction. Most people would forget all their socialization if left hungry and thirsty for days in the jungle. But more often than not, survival and reproduction depend on being high status; having a good name among your peers is the best way to get food, housing and hot mates.

The way to raise one’s SP number depends on thousands of different factors. We could grab most of them and call them “culture”. In China having 20 teenage mistresses as an old man raises your SP; in Western polite society it is social death. In the West making a fuss about disobeying one’s parents raises your SP, everywhere else it lowers it a great deal. People know that; which is why bureaucrats in China go to great lengths to acquire a stash of young women (who they seldom have time to actually enjoy), while teenagers in the West go to great lengths to be annoying to their parents for no good reason.

...

It thus shouldn’t surprise us that something as completely absurd as Progressivism is the law of the land in most of the world today, even though it denies obvious reality. It is not the case that most people know that progressive points are all bogus, but obey because of fear or cowardice. No, an average human brain has much more neurons being used to scan the social climate and see how SP are allotted, than neurons being used to analyze patterns in reality to ascertain the truth. Surely your brain does care a great deal about truth in some very narrow areas of concern to you. Remember Conquest’s first law: Everybody is Conservative about what he knows best. You have to know the truth about what you do, if you are to do it effectively.

But you don’t really care about truth anywhere else. And why would you? It takes time and effort you can’t really spare, and it’s not really necessary. As long as you have some area of specialization where you can make a living, all the rest you must do to achieve survival and reproduction is to raise your SP so you don’t get killed and your guts sacrificed to the mountain spirits.

SP theory (I accept suggestions for a better name) can also explains the behavior of leftists. Many conservatives of a medium level of enlightenment point out the paradox that leftists historically have held completely different ideas. Leftism used to be about the livelihood of industrial workers, now they agitate about the environment, or feminism, or foreigners. Some people would say that’s just historical change, or pull a No True Scotsman about this or that group not being really leftists. But that’s transparent bullshit; very often we see a single person shifting from agitating about Communism and worker rights, to agitate about global warming or rape culture.

...

The leftist strategy could be defined as “psychopathic SP maximization”. Leftists attempt to destroy social equilibrium so that they can raise their SP number. If humans are, in a sense, programmed to constantly raise their status, well high status people by definition can’t raise it anymore (though they can squabble against each other for marginal gains), their best strategy is to freeze society in place so that they can enjoy their superiority. High status people by definition have power, and thus social hierarchy during human history tends to be quite stable.

This goes against the interests of many. First of all the lower status people, who, well, want to raise their status, but can’t manage to do so. And it also goes against the interests of the particularly annoying members of the upper class who want to raise their status on the margin. Conservative people can be defined as those who, no matter the absolute level, are in general happy with it. This doesn’t mean they don’t want higher status (by definition all humans do), but the output of other brain modules may conclude that attempts to raise SP might threaten one’s survival and reproduction; or just that the chances of raising one’s individual SP is hopeless, so one might as well stay put.

...

You can’t blame people for being logically inconsistent; because they can’t possibly know anything about all these issues. Few have any experience or knowledge about evolution and human races, or about the history of black people to make an informed judgment on HBD. Few have time to learn about sex differences, and stuff like the climate is as close to unknowable as there is. Opinions about anything but a very narrow area of expertise are always output of your SP module, not any judgment of fact. People don’t know the facts. And even when they know; I mean most people have enough experience with sex differences and black dysfunction to be quite confident that progressive ideas are false. But you can never be sure. As Hume said, the laws of physics are a judgment of habit; who is to say that a genie isn’t going to change all you know the next morning? At any rate, you’re always better off toeing the line, following the conventional wisdom, and keeping your dear SP. Perhaps you can even raise them a bit. And that is very nice. It is niceness itself.

Leftism is just an easy excuse: https://bloodyshovel.wordpress.com/2015/03/01/leftism-is-just-an-easy-excuse/
Unless you’re not the only defector. You need a way to signal your intention to defect, so that other disloyal fucks such as yourself (and they’re bound to be others) can join up, thus reducing the likely costs of defection. The way to signal your intention to defect is to come up with a good excuse. A good excuse to be disloyal becomes a rallying point through which other defectors can coordinate and cover their asses so that the ruling coalition doesn’t punish them. What is a good excuse?

Leftism is a great excuse. Claiming that the ruling coalition isn’t leftist enough, isn’t holy enough, not inclusive enough of women, of blacks, of gays, or gorillas, of pedophiles, of murderous Salafists, is the perfect way of signalling your disloyalty towards the existing power coalition. By using the existing ideology and pushing its logic just a little bit, you ensure that the powerful can’t punish you. At least not openly. And if you’re lucky, the mass of disloyal fucks in the ruling coalition might join your banner, and use your exact leftist point to jump ship and outflank the powerful.

...

The same dynamic fuels the flattery inflation one sees in monarchical or dictatorial systems. In Mao China, if you want to defect, you claim to love Mao more than your boss. In Nazi Germany, you proclaim your love for Hitler and the great insight of his plan to take Stalingrad. In the Roman Empire, you claimed that Caesar is a God, son of Hercules, and those who deny it are treacherous bastards. In Ancient Persia you loudly proclaimed your faith in the Shah being the brother of the Sun and the Moon and King of all Kings on Earth. In Reformation Europe you proclaimed that you have discovered something new in the Bible and everybody else is damned to hell. Predestined by God!

...

And again: the precise content of the ideological point doesn’t matter. Your human brain doesn’t care about ideology. Humans didn’t evolve to care about Marxist theory of class struggle, or about LGBTQWERTY theories of social identity. You just don’t know what it means. It’s all abstract points you’ve been told in a classroom. It doesn’t actually compute. Nothing that anybody ever said in a political debate ever made any actual, concrete sense to a human being.

So why do we care so much about politics? What’s the point of ideology? Ideology is just the water you swim in. It is a structured database of excuses, to be used to signal your allegiance or defection to the existing ruling coalition. Ideology is just the feed of the rationalization Hamster that runs incessantly in that corner of your brain. But it is immaterial, and in most cases actually inaccessible to the logical modules in your brain.

Nobody ever acts on their overt ideological claims if they can get away with it. Liberals proclaim their faith in the potential of black children while clustering in all white suburbs. Communist party members loudly talk about the proletariat while being hedonistic spenders. Al Gore talks about Global Warming while living in a lavish mansion. Cognitive dissonance, you say? No; those cognitive systems are not connected in the first place.

...

And so, every little step in the way, power-seekers moved the consensus to the left. And open societies, democratic systems are by their decentralized nature, and by the size of their constituencies, much more vulnerable to this sort of signalling attacks. It is but impossible to appraise and enforce the loyalty of every single individual involved in a modern state. There’s too many of them. A Medieval King had a better chance of it; hence the slow movement of ideological innovation in those days. But the bigger the organization, the harder it is to gather accurate information of the loyalty of the whole coalition; and hence the ideological movement accelerates. And there is no stopping it.

Econometric Modeling as Junk Science
The Credibility Revolution in Empirical Economics: How Better Research Design Is Taking the Con out of Econometrics: https://www.aeaweb.org/articles?id=10.1257/jep.24.2.3

On data, experiments, incentives and highly unconvincing research – papers and hot beverages: https://papersandhotbeverages.wordpress.com/2015/10/31/on-data-experiments-incentives-and-highly-unconvincing-research/
In my view, it has just to do with the fact that academia is a peer monitored organization. In the case of (bad) data collection papers, issues related to measurement are typically boring. They are relegated to appendices, no one really has an incentive to monitor it seriously. The problem is similar in formal theory: no one really goes through the algebra in detail, but it is in principle feasible to do it, and, actually, sometimes these errors are detected. If discussing the algebra of a proof is almost unthinkable in a seminar, going into the details of data collection, measurement and aggregation is not only hard to imagine, but probably intrinsically infeasible.

Something different happens for the experimentalist people. As I was saying, I feel we have come to a point in which many papers are evaluated based on the cleverness and originality of the research design (“Using the World Cup qualifiers as an instrument for patriotism!? Woaw! how cool/crazy is that! I wish I had had that idea”). The sexiness of the identification strategy has too often become a goal in itself. When your peers monitor you paying more attention to the originality of the identification strategy than to the research question, you probably have an incentive to mine reality for ever crazier discontinuities. It is true methodologists have been criticized in the past for analogous reasons, such as being guided by the desire to increase mathematical complexity without a clear benefit. But, if you work with pure formal theory or statistical theory, your work is not meant to immediately answer question about the real world, but instead to serve other researchers in their quest. This is something that can, in general, not be said of applied CI work.

This post should have been entitled “Zombies who only think of their next cool IV fix”
massive lust for quasi-natural experiments, regression discontinuities
barely matters if the effects are not all that big
I suppose even the best of things must reach their decadent phase; methodological innov. to manias……

Following this "collapse of small-N social psych results" business, where do I predict econ will collapse? I see two main contenders.
One is lab studies. I dallied with these a few years ago in a Kenya lab. We ran several pilots of N=200 to figure out the best way to treat
and to measure the outcome. Every pilot gave us a different stat sig result. I could have written six papers concluding different things.
I gave up more skeptical of these lab studies than ever before. The second contender is the long run impacts literature in economic history
We should be very suspicious since we never see a paper showing that a historical event had no effect on modern day institutions or dvpt.
On the one hand I find these studies fun, fascinating, and probably true in a broad sense. They usually reinforce a widely believed history
argument with interesting data and a cute empirical strategy. But I don't think anyone believes the standard errors. There's probably a HUGE
problem of nonsignificant results staying in the file drawer. Also, there are probably data problems that don't get revealed, as we see with
the recent Piketty paper (http://marginalrevolution.com/marginalrevolution/2017/10/pikettys-data-reliable.html). So I take that literature with a vat of salt, even if I enjoy and admire the works
I used to think field experiments would show little consistency in results across place. That external validity concerns would be fatal.
In fact the results across different samples and places have proven surprisingly similar across places, and added a lot to general theory
Last, I've come to believe there is no such thing as a useful instrumental variable. The ones that actually meet the exclusion restriction
are so weird & particular that the local treatment effect is likely far different from the average treatment effect in non-transparent ways.
Most of the other IVs don't plausibly meet the e clue ion restriction. I mean, we should be concerned when the IV estimate is always 10x
larger than the OLS coefficient. This I find myself much more persuaded by simple natural experiments that use OLS, diff in diff, or
discontinuities, alongside randomized trials.

What do others think are the cliffs in economics?
PS All of these apply to political science too. Though I have a special extra target in poli sci: survey experiments! A few are good. I like
Dan Corstange's work. But it feels like 60% of dissertations these days are experiments buried in a survey instrument that measure small
changes in response. These at least have large N. But these are just uncontrolled labs, with negligible external validity in my mind.
The good ones are good. This method has its uses. But it's being way over-applied. More people have to make big and risky investments in big
natural and field experiments. Time to raise expectations and ambitions. This expectation bar, not technical ability, is the big advantage
economists have over political scientists when they compete in the same space.
(Ok. So are there any friends and colleagues I haven't insulted this morning? Let me know and I'll try my best to fix it with a screed)

HOW MUCH SHOULD WE TRUST DIFFERENCES-IN-DIFFERENCES ESTIMATES?∗: https://economics.mit.edu/files/750
Most papers that employ Differences-in-Differences estimation (DD) use many years of data and focus on serially correlated outcomes but ignore that the resulting standard errors are inconsistent. To illustrate the severity of this issue, we randomly generate placebo laws in state-level data on female wages from the Current Population Survey. For each law, we use OLS to compute the DD estimate of its “effect” as well as the standard error of this estimate. These conventional DD standard errors severely understate the standard deviation of the estimators: we find an “effect” significant at the 5 percent level for up to 45 percent of the placebo interventions. We use Monte Carlo simulations to investigate how well existing methods help solve this problem. Econometric corrections that place a specific parametric form on the time-series process do not perform well. Bootstrap (taking into account the auto-correlation of the data) works well when the number of states is large enough. Two corrections based on asymptotic approximation of the variance-covariance matrix work well for moderate numbers of states and one correction that collapses the time series information into a “pre” and “post” period and explicitly takes into account the effective sample size works well even for small numbers of states.

‘METRICS MONDAY: 2SLS–CHRONICLE OF A DEATH FORETOLD: http://marcfbellemare.com/wordpress/12733
As it turns out, Young finds that
1. Conventional tests tend to overreject the null hypothesis that the 2SLS coefficient is equal to zero.
2. 2SLS estimates are falsely declared significant one third to one half of the time, depending on the method used for bootstrapping.
3. The 99-percent confidence intervals (CIs) of those 2SLS estimates include the OLS point estimate over 90 of the time. They include the full OLS 99-percent CI over 75 percent of the time.
4. 2SLS estimates are extremely sensitive to outliers. Removing simply one outlying cluster or observation, almost half of 2SLS results become insignificant. Things get worse when removing two outlying clusters or observations, as over 60 percent of 2SLS results then become insignificant.
5. Using a Durbin-Wu-Hausman test, less than 15 percent of regressions can reject the null that OLS estimates are unbiased at the 1-percent level.
6. 2SLS has considerably higher mean squared error than OLS.
7. In one third to one half of published results, the null that the IVs are totally irrelevant cannot be rejected, and so the correlation between the endogenous variable(s) and the IVs is due to finite sample correlation between them.
8. Finally, fewer than 10 percent of 2SLS estimates reject instrument irrelevance and the absence of OLS bias at the 1-percent level using a Durbin-Wu-Hausman test. It gets much worse–fewer than 5 percent–if you add in the requirement that the 2SLS CI that excludes the OLS estimate.

Methods Matter: P-Hacking and Causal Inference in Economics*: http://ftp.iza.org/dp11796.pdf
Applying multiple methods to 13,440 hypothesis tests reported in 25 top economics journals in 2015, we show that selective publication and p-hacking is a substantial problem in research employing DID and (in particular) IV. RCT and RDD are much less problematic. Almost 25% of claims of marginally significant results in IV papers are misleading.

Ever since I learned social science is completely fake, I've had a lot more time to do stuff that matters, like deadlifting and reading about Mediterranean haplogroups

Wait, so, from fakest to realest IV>DD>RCT>RDD? That totally matches my impression.

Logic | West Hunter
All the time I hear some public figure saying that if we ban or allow X, then logically we have to ban or allow Y, even though there are obvious practical reasons for X and obvious practical reasons against Y.

No, we don’t.

And on reflection it occurs to me that this is actually THE standard debate about change: some see small changes and either like them or aren’t bothered enough to advocate what it would take to reverse them, while others imagine such trends continuing long enough to result in very large and disturbing changes, and then suggest stronger responses.

For example, on increased immigration some point to the many concrete benefits immigrants now provide. Others imagine that large cumulative immigration eventually results in big changes in culture and political equilibria. On fertility, some wonder if civilization can survive in the long run with declining population, while others point out that population should rise for many decades, and few endorse the policies needed to greatly increase fertility. On genetic modification of humans, some ask why not let doctors correct obvious defects, while others imagine parents eventually editing kid genes mainly to max kid career potential. On oil some say that we should start preparing for the fact that we will eventually run out, while others say that we keep finding new reserves to replace the ones we use.

...

If we consider any parameter, such as typical degree of mind wandering, we are unlikely to see the current value as exactly optimal. So if we give people the benefit of the doubt to make local changes in their interest, we may accept that this may result in a recent net total change we don’t like. We may figure this is the price we pay to get other things we value more, and we we know that it can be very expensive to limit choices severely.

But even though we don’t see the current value as optimal, we also usually see the optimal value as not terribly far from the current value. So if we can imagine current changes as part of a long term trend that eventually produces very large changes, we can become more alarmed and willing to restrict current changes. The key question is: when is that a reasonable response?

First, big concerns about big long term changes only make sense if one actually cares a lot about the long run. Given the usual high rates of return on investment, it is cheap to buy influence on the long term, compared to influence on the short term. Yet few actually devote much of their income to long term investments. This raises doubts about the sincerity of expressed long term concerns.

Second, in our simplest models of the world good local choices also produce good long term choices. So if we presume good local choices, bad long term outcomes require non-simple elements, such as coordination, commitment, or myopia problems. Of course many such problems do exist. Even so, someone who claims to see a long term problem should be expected to identify specifically which such complexities they see at play. It shouldn’t be sufficient to just point to the possibility of such problems.

...

Fourth, many more processes and factors limit big changes, compared to small changes. For example, in software small changes are often trivial, while larger changes are nearly impossible, at least without starting again from scratch. Similarly, modest changes in mind wandering can be accomplished with minor attitude and habit changes, while extreme changes may require big brain restructuring, which is much harder because brains are complex and opaque. Recent changes in market structure may reduce the number of firms in each industry, but that doesn’t make it remotely plausible that one firm will eventually take over the entire economy. Projections of small changes into large changes need to consider the possibility of many such factors limiting large changes.

Fifth, while it can be reasonably safe to identify short term changes empirically, the longer term a forecast the more one needs to rely on theory, and the more different areas of expertise one must consider when constructing a relevant model of the situation. Beware a mere empirical projection into the long run, or a theory-based projection that relies on theories in only one area.

We should very much be open to the possibility of big bad long term changes, even in areas where we are okay with short term changes, or at least reluctant to sufficiently resist them. But we should also try to hold those who argue for the existence of such problems to relatively high standards. Their analysis should be about future times that we actually care about, and can at least roughly foresee. It should be based on our best theories of relevant subjects, and it should consider the possibility of factors that limit larger changes.

And instead of suggesting big ways to counter short term changes that might lead to long term problems, it is often better to identify markers to warn of larger problems. Then instead of acting in big ways now, we can make sure to track these warning markers, and ready ourselves to act more strongly if they appear.

Growth Is Change. So Is Death.: https://www.overcomingbias.com/2018/03/growth-is-change-so-is-death.html
I see the same pattern when people consider long term futures. People can be quite philosophical about the extinction of humanity, as long as this is due to natural causes. Every species dies; why should humans be different? And few get bothered by humans making modest small-scale short-term modifications to their own lives or environment. We are mostly okay with people using umbrellas when it rains, moving to new towns to take new jobs, etc., digging a flood ditch after our yard floods, and so on. And the net social effect of many small changes is technological progress, economic growth, new fashions, and new social attitudes, all of which we tend to endorse in the short run.

Even regarding big human-caused changes, most don’t worry if changes happen far enough in the future. Few actually care much about the future past the lives of people they’ll meet in their own life. But for changes that happen within someone’s time horizon of caring, the bigger that changes get, and the longer they are expected to last, the more that people worry. And when we get to huge changes, such as taking apart the sun, a population of trillions, lifetimes of millennia, massive genetic modification of humans, robots replacing people, a complete loss of privacy, or revolutions in social attitudes, few are blasé, and most are quite wary.

This differing attitude regarding small local changes versus large global changes makes sense for parameters that tend to revert back to a mean. Extreme values then do justify extra caution, while changes within the usual range don’t merit much notice, and can be safely left to local choice. But many parameters of our world do not mostly revert back to a mean. They drift long distances over long times, in hard to predict ways that can be reasonably modeled as a basic trend plus a random walk.

This different attitude can also make sense for parameters that have two or more very different causes of change, one which creates frequent small changes, and another which creates rare huge changes. (Or perhaps a continuum between such extremes.) If larger sudden changes tend to cause more problems, it can make sense to be more wary of them. However, for most parameters most change results from many small changes, and even then many are quite wary of this accumulating into big change.

For people with a sharp time horizon of caring, they should be more wary of long-drifting parameters the larger the changes that would happen within their horizon time. This perspective predicts that the people who are most wary of big future changes are those with the longest time horizons, and who more expect lumpier change processes. This prediction doesn’t seem to fit well with my experience, however.

Those who most worry about big long term changes usually seem okay with small short term changes. Even when they accept that most change is small and that it accumulates into big change. This seems incoherent to me. It seems like many other near versus far incoherences, like expecting things to be simpler when you are far away from them, and more complex when you are closer. You should either become more wary of short term changes, knowing that this is how big longer term change happens, or you should be more okay with big long term change, seeing that as the legitimate result of the small short term changes you accept.

The point here is the gradual shifts of in-group beliefs are both natural and no big deal. Humans are built to readily do this, and forget they do this. But ultimately it is not a worry or concern.

But radical shifts that are big, whether near or far, portend strife and conflict. Either between groups or within them. If the shift is big enough, our intuition tells us our in-group will be in a fight. Alarms go off.

Lucio Russo - Wikipedia
In The Forgotten Revolution: How Science Was Born in 300 BC and Why It Had to Be Reborn (Italian: La rivoluzione dimenticata), Russo promotes the belief that Hellenistic science in the period 320-144 BC reached heights not achieved by Classical age science, and proposes that it went further than ordinarily thought, in multiple fields not normally associated with ancient science.

La Rivoluzione Dimenticata (The Forgotten Revolution), Reviewed by Sandro Graffi: http://www.ams.org/notices/199805/review-graffi.pdf

Before turning to the question of the decline of Hellenistic science, I come back to the new light shed by the book on Euclid’s Elements and on pre-Ptolemaic astronomy. Euclid’s definitions of the elementary geometric entities—point, straight line, plane—at the beginning of the Elements have long presented a problem.7 Their nature is in sharp contrast with the approach taken in the rest of the book, and continued by mathematicians ever since, of refraining from defining the fundamental entities explicitly but limiting themselves to postulating the properties which they enjoy. Why should Euclid be so hopelessly obscure right at the beginning and so smooth just after? The answer is: the definitions are not Euclid’s. Toward the beginning of the second century A.D. Heron of Alexandria found it convenient to introduce definitions of the elementary objects (a sign of decadence!) in his commentary on Euclid’s Elements, which had been written at least 400 years before. All manuscripts of the Elements copied ever since included Heron’s definitions without mention, whence their attribution to Euclid himself. The philological evidence leading to this conclusion is quite convincing.8

...

What about the general and steady (on the average) impoverishment of Hellenistic science under the Roman empire? This is a major historical problem, strongly tied to the even bigger one of the decline and fall of the antique civilization itself. I would summarize the author’s argument by saying that it basically represents an application to science of a widely accepted general theory on decadence of antique civilization going back to Max Weber. Roman society, mainly based on slave labor, underwent an ultimately unrecoverable crisis as the traditional sources of that labor force, essentially wars, progressively dried up. To save basic farming, the remaining slaves were promoted to be serfs, and poor free peasants reduced to serfdom, but this made trade disappear. A society in which production is almost entirely based on serfdom and with no trade clearly has very little need of culture, including science and technology. As Max Weber pointed out, when trade vanished, so did the marble splendor of the ancient towns, as well as the spiritual assets that went with it: art, literature, science, and sophisticated commercial laws. The recovery of Hellenistic science then had to wait until the disappearance of serfdom at the end of the Middle Ages. To quote Max Weber: “Only then with renewed vigor did the old giant rise up again.”

...

The epilogue contains the (rather pessimistic) views of the author on the future of science, threatened by the apparent triumph of today’s vogue of irrationality even in leading institutions (e.g., an astrology professorship at the Sorbonne). He looks at today’s ever-increasing tendency to teach science more on a fideistic than on a deductive or experimental basis as the first sign of a decline which could be analogous to the post-Hellenistic one.

Justified by more than logos alone - The Unz Review
The scientific study of religion is another topic where I once had a lot of interest, but where I concluded that the basic insights have stabilized. Since I stopped reading much in this area I stopped writing much about it too. To get a sense of where I’m coming from, Scott Atran’s In Gods We Trust: The Evolutionary Landscape of Religion is probably the best place to start. It’s about 15 years old, but I don’t see that much has changed since then in the basics of the field.

And what are those basics? At its fundamental basics religious impulses must be understood as an outcome of our cognitive mental intuitions. All religion operates on top of this basic kernel of our mental OS. Religion may have functional utility as a social system of control, or channeling collective energies, as argued by David Sloan Wilson in Darwin’s Cathedral. Or, one might be able to fruitfully model “religious marketplaces” as argued in Marketplace of the Gods. But these are all basically simply applications installed into on top of the operating system.

...

Very few are Roman Catholic because they have read Aquinas’ Five Ways. Rather, they are Roman Catholic, in order of necessity, because God aligns with their deep intuitions, basic cognitive needs in terms of cosmological coherency, and because the church serves as an avenue for socialization and repetitive ritual which binds individuals to the greater whole. People do not believe in Catholicism as often as they are born Catholics, and the Catholic religion is rather well fitted to a range of predispositions to the typical human.

...

There are a subset of believers who are not well captured by the generalizations in books such as Slone’s, or in ethnographic descriptions which trace the assimilation of Catholicism into the American scene. They are usually highly intellectual and analytical in their orientation. Often, they seem to be converts. Rod Dreher was a convert to Catholicism from Methodism, before he became Orthodox. Leah Libresco and Eve Tushnet also seem to fall into this category. Highly intellectual. And, converts to Catholicism.

Because they are analytical and articulate, these sorts of religious people are highly prominent on the public stage, and, they also write the histories that come down to us through the centuries. These are also the type of people who are overrepresented in the clerical apparatus of any organized religion. This is a problem, because their prominence can obscure the reality that they are not as influential as you might think. As a metaphor, imagine mountainous islands scattering amidst a featureless ocean. The islands are salient. But it is the vast ocean which will ultimately be determinative. Similarly, the vast number of believers who move along a nexus of inscrutable social forces, and driven by powerful universal psychologies, may be hidden from our view.

And yet even for the “analytics” reason does not dictate. Both Dreher and Tushnet have made references to mystical and emotional occurrences and impulses which are beyond my ken. I have no need, no wish, no impulse, and no intuition as to what they are talking about in that dimension (Libresco seems a somewhat different case, but I haven’t read much of what she’s written; I suspect I’ve been in the same room with her since she worked for an organization which I have many personal connections with, but I’m not sure).

It isn’t a surprise that I think Hume was onto something when he asserted that “reason is a slave to the passions.” In many instances I suspect theological analysis is simply the analytic engine being applied to a domain whose ultimate rationale is driven by a passion.

Addendum: Leah Libresco seems to have been associated with the broad umbrella group of Bay Area rationalists. I’ve been associated in some fashion with these people as friends and acquaintances for nearly 10 years. I will admit that I’ve generally found the conceit of rationality as an ends, as opposed to a means, somewhat off-putting. Ultimately I’m more of a skeptic than a rationalist I suppose at the root.

This is the hard part for many intellectuals, religious or irreligious, to understand. For intellectuals ideas have consequences, and they shape their lives. Their religious world view is naturally inflected by this. And most importantly they confuse their own comprehension of religious life, the profession of creeds rationally understand and mystical reflection viscerally experienced, with modal religiosity. This has important consequences, because intellectuals write, and writing is permanent. It echoes down through the ages. Therefore our understanding of the broad scope of religious history is naturally shaped by how intellectuals view religion. In a superficial sense the history of religion is the history of theology, because theology is so amenable to preservation.

What Religion Is: https://www.gnxp.com/WordPress/2018/01/12/what-religion-is/
It’s been about 10 years since I addressed this topic. Largely because I have no new thoughts. But probably after 10 years, it’s useful to revisit/clarify on this topic to clarify confusions, since people have a lot of opinions on this topic.

People mean different things when they mean “religion,” and the different meanings are not contradictory, nor in conflict.

At the lowest level in terms of individual cognition religion emerges from deep intuitions about the nature of the universe. Colloquially one might say that religion bubbles out of our unconscious.

In relation to social units, say the clan or tribe, religion consists of these intuitions about the nature of the universe and the world around us, bound together with rituals and verbal descriptions and narratives. These rituals and communal narratives help forge some sort of group Weltanschauung that has a functional utility in terms of inter-group competition and relations. Here religion steps out of the individual and becomes an expression of collective consensus.

As human societies became more complex the role of religious professionals became more elaborated. The common role of a shaman can be thought of as a magician, one who manipulates and operates in the domain of the supernatural. Shamans are common and ubiquitous in pre-state societies (even if a tribe does not have a “professional” shaman, someone takes on the role when needed). The priest adds on top of this institutional authority, often supra-clan or tribal. No king, no priest. Eventually, though the shaman-priest took on the role of the metaphysician. The metaphysician generates abstract principles and rationales, which can transcend the tribe or ethnicity, and allows religion to generate meta-ethnic civilizational identities in the service of priestly functions.

So in the post-Axial Age, the religious professional is often shaman, priest, and philosopher.

...

What about the priest? Though I am wary of the term “political religion,” due to semantic confusion, it seems clear that the function of the priest can be stripped of its supernatural valence. Many of the most objectionable characteristics of religion for people of liberal orientations derives from the institutionalized priestly functions. Unfortunately, the persistence of the priest in the absence of gods, shamanic powers and metaphysical justification opens the doors to secular totalitarianism.

...

These different aspects of religiosity exist and persist simultaneously in most contexts, but sometimes in tension. Philosophers and priests often take a dim view of shamanic religiosity. In organized religion of the modern sort shamanism is marginalized, or highly constrained and regulated in sacraments. But the recession of state-sponsored Christianity across much of the West has arguably resulted in a resurgence of shamanism, and the proliferation of diverse supernatural beliefs which had previously been suppressed (much of East Asia is characterized by relative weakness of philosophical religion but the strength of shamanism).

The relevance of all this in relation to New Atheism is that New Atheism seems to posit a religious “Blank Slate.” That is, children are indoctrinated in religion at a small age, previous to which they had been atheists. Part of this is due to the fact that the philosophical-metaphysical aspect of religion is quite clearly indoctrination, and often of a superficial sort at that (judging by how weak most believer’s grasp of theology is). But the communal and psychological aspects are not indoctrination, as much as specific instantiations of general human sentiments, dispositions, and intuitions. The erasure of a Christian, Buddhist or Islamic religious orientation will not necessarily leave in its wake a mind primed for scientific naturalism. Rather, it will simply be one shorn of Axial-Age accretions, reverted back to the shamanic age…

Atheism As Mental Deviance: http://www.gnxp.com/WordPress/2011/09/18/atheism-as-mental-deviance/
Tyler Cowen points me to a PDF, Religious Belief Systems of Persons with High Functioning Autism, which has some fascinating results on the religiosity (or lack thereof) of people with high functioning autism. I’ve seen speculation about the peculiar psychological profile of atheists before in the cognitive science literature, and there’s a fair amount of social psychological data on the different personality profile of atheists (e.g., more disagreeable). But there hasn’t been a lot of systematic investigation of the possibility that autistic individuals are more likely to be atheist because they lack a fully fleshed “theory of mind,” which … [more]

INFECTIOUS CAUSATION OF DISEASE: AN EVOLUTIONARY PERSPECTIVE
A New Germ Theory: https://www.theatlantic.com/magazine/archive/1999/02/a-new-germ-theory/377430/
The dictates of evolution virtually demand that the causes of some of humanity's chronic and most baffling "noninfectious" illnesses will turn out to be pathogens -- that is the radical view of a prominent evolutionary biologist

A LATE-SEPTEMBER heat wave enveloped Amherst College, and young people milled about in shorts or sleeveless summer frocks, or read books on the grass. Inside the red-brick buildings framing the leafy quadrangle students listened to lectures on Ellison and Emerson, on Paul Verlaine and the Holy Roman Empire. Few suspected that strains of the organism that causes cholera were growing nearby, in the Life Sciences Building. If they had known, they would probably not have grasped the implications. But these particular strains of cholera make Paul Ewald smile; they are strong evidence that he is on the right track. Knowing the rules of evolutionary biology, he believes, can change the course of infectious disease.

https://www.theatlantic.com/past/docs/issues/99feb/germ2.htm
I HAVE a motto," Gregory Cochran told me recently. "'Big old diseases are infectious.' If it's common, higher than one in a thousand, I get suspicious. And if it's old, if it has been around for a while, I get suspicious."

In our genes
The D4 dopamine receptor (DRD4) locus may be a model system for understanding the relationship between genetic variation and human cultural diversity. It has been the subject of intense interest in psychiatry, because bearers of one variant are at increased risk for attention deficit hyperactivity disorder (ADHD) (1). A survey of world frequencies of DRD4 alleles has shown striking differences among populations (2), with population differences greater than those of most neutral markers. In this issue of PNAS Ding et al. (3) provide a detailed molecular portrait of world diversity at the DRD4 locus. They show that the allele associated with ADHD has increased a lot in frequency within the last few thousands to tens of thousands of years, although it has probably been present in our ancestors for hundreds of thousands or even millions of years.

Because the prominent phenotypic effects of 7R are in males, we need to ask what is the niche in human societies for males who are energetic, impulsive (i.e., unpredictable), and noncompliant? Whereas tests of hypotheses ought to be careful and conservative, generation of hypotheses ought to be speculative and free-ranging. There is a tradition of caution approaching self-censorship in discussions of human biological diversity, but we will break that tradition in what follows.

Wizard War | West Hunter
Some of his successes were classically thin, as when he correctly analyzed the German two-beam navigation system (Knickebein). He realize that the area of overlap of two beams could be narrow, far narrower than suggested by the Rayleigh criterion.

During the early struggle with the Germans, the “Battle of the Beams”, he personally read all the relevant Enigma messages. They piled up on his desk, but he could almost always pull out the relevant message, since he remembered the date, which typewriter it had been typed on, and the kind of typewriter ribbon or carbon. When asked, he could usually pick out the message in question in seconds. This system was deliberate: Jones believed that the larger the field any one man could cover, the greater the chance of one brain connecting two facts – the classic approach to a ‘thick’ problem, not that anyone seems to know that anymore.

All that information churning in his head produced results, enough so that his bureaucratic rivals concluded that he had some special unshared source of information. They made at least three attempts to infiltrate his Section to locate this great undisclosed source. An officer from Bletchley Park was offered on a part-time basis with that secret objective. After a month or so he was called back, and assured his superiors that there was no trace of anything other than what they already knew. When someone asked ‘Then how does Jones do it? ‘ he replied ‘Well, I suppose, Sir, he thinks!’

Not Final! | West Hunter
In mathematics we often prove that some proposition is true by showing that  the alternative is false.  The principle can sometimes work in other disciplines, but it’s tricky.  You have to have a very good understanding  to know that some things are impossible (or close enough to impossible).   You can do it fairly often in physics, less often in biology.

Thick and thin | West Hunter
There is a spectrum of problem-solving, ranging from, at one extreme, simplicity and clear chains of logical reasoning (sometimes long chains) and, at the other, building a picture by sifting through a vast mass of evidence of varying quality. I will give some examples. Just the other day, when I was conferring, conversing and otherwise hobnobbing with my fellow physicists, I mentioned high-altitude lighting, sprites and elves and blue jets. I said that you could think of a thundercloud as a vertical dipole, with an electric field that decreased as the cube of altitude, while the breakdown voltage varied with air pressure, which declines exponentially with altitude. At which point the prof I was talking to said ” and so the curves must cross!”. That’s how physicists think, and it can be very effective. The amount of information required to solve the problem is not very large. I call this a ‘thin’ problem’.

...

In another example at the messy end of the spectrum, Joe Rochefort, running Hypo in the spring of 1942, needed to figure out Japanese plans. He had an an ever-growing mass of Japanese radio intercepts, some of which were partially decrypted – say, one word of five, with luck. He had data from radio direction-finding; his people were beginning to be able to recognize particular Japanese radio operators by their ‘fist’. He’d studied in Japan, knew the Japanese well. He had plenty of Navy experience – knew what was possible. I would call this a classic ‘thick’ problem, one in which an analyst needs to deal with an enormous amount of data of varying quality. Being smart is necessary but not sufficient: you also need to know lots of stuff.

...

Nimitz believed Rochefort – who was correct. Because of that, we managed to prevail at Midway, losing one carrier and one destroyer while the the Japanese lost four carriers and a heavy cruiser*. As so often happens, OP-20-G won the bureaucratic war: Rochefort embarrassed them by proving them wrong, and they kicked him out of Hawaii, assigning him to a floating drydock.

The usual explanation of Joe Rochefort’s fall argues that John Redman’s ( head of OP-20-G, the Navy’s main signals intelligence and cryptanalysis group) geographical proximity to Navy headquarters was a key factor in winning the bureaucratic struggle, along with his brother’s influence (Rear Admiral Joseph Redman). That and being a shameless liar.

Personally, I wonder if part of the problem is the great difficulty of explaining the analysis of a thick problem to someone without a similar depth of knowledge. At best, they believe you because you’ve been right in the past. Or, sometimes, once you have developed the answer, there is a ‘thin’ way of confirming your answer – as when Rochefort took Jasper Holmes’s suggestion and had Midway broadcast an uncoded complaint about the failure of their distillation system – soon followed by a Japanese report that ‘AF’ was short of water.

Most problems in the social sciences are ‘thick’, and unfortunately, almost all of the researchers are as well. There are a lot more Redmans than Rocheforts.

Son of low-hanging fruit | West Hunter
You see, you can think of the thunderstorm, after a ground discharge, as a vertical dipole. Its electrical field drops as the cube of altitude. The threshold voltage for atmospheric breakdown is proportional to pressure, while pressure drops exponentially with altitude: and as everyone knows, a negative exponential drops faster than any power.

The curves must cross. Electrical breakdown occurs. Weird lightning, way above the clouds.

As I said, people reported sprites at least a hundred years ago, and they have probably been observed occasionally since the dawn of time. However, they’re far easier to see if you’re above the clouds – pilots often do.

Pilots also learned not to talk about it, because nobody listened. Military and commercial pilots have to pass periodic medical exams known as ‘flight physicals’, and there was a suspicion that reporting glowing red cephalopods in the sky might interfere with that. Generally, you had to see the things that were officially real (whether they were really real or not), and only those things.

Sprites became real when someone recorded one by accident on a fast camera in 1989. Since then it’s turned into a real subject, full of strangeness: turns out that thunderstorms sometimes generate gamma-rays and even antimatter.

Hidden Games | West Hunter
Since we are arguably a lot smarter than ants or bees, you might think that most adaptive personality variation in humans would be learned (a response to exterior cues) rather than heritable. Maybe some is, but much variation looks heritable. People don’t seem to learn to be aggressive or meek – they just are, and in those tendencies resemble their biological parents. I wish I (or anyone else) understood better why this is so, but there are some notions floating around that may explain it. One is that jacks of all trades are masters of none: if you play the same role all the time, you’ll be better at it than someone who keep switching personalities. It could be the case that such switching is physiologically difficult and/or expensive. And in at least some cases, being predictable has social value. Someone who is known to be implacably aggressive will win at ‘chicken’. Being known as the sort of guy who would rush into a burning building to save ugly strangers may pay off, even though actually running into that blaze does not.

...

This kind of game-theoretic genetic variation, driving distinct behavioral strategies, can have some really odd properties. For one thing, there can be more than one possible stable mix of behavioral types even in identical ecological situations. It’s a bit like dropping a marble onto a hilly landscape with many unconnected valleys – it will roll to the bottom of some valley, but initial conditions determine which valley. Small perturbations will not knock the marble out of the valley it lands in. In the same way, two human populations could fall into different states, different stable mixes of behavioral traits, for no reason at all other than chance and then stay there indefinitely. Populations are even more likely to fall into qualitatively different stable states when the ecological situations are significantly different.

...

What this means, think, is that it is entirely possible that human societies fall into fundamentally different patterns because of genetic influences on behavior that are best understood via evolutionary game theory. Sometimes one population might have a psychological type that doesn’t exist at all in another society, or the distribution could be substantially different. Sometimes these different social patterns will be predictable results of different ecological situations, sometimes the purest kind of chance. Sometimes the internal dynamics of these genetic systems will produce oscillatory (or chaotic!) changes in gene frequencies over time, which means changes in behavior and personality over time. In some cases, these internal genetic dynamics may be the fundamental reason for the rise and fall of empires. Societies in one stable distribution, in a particular psychological/behavioral/life history ESS, may simply be unable to replicate some of the institutions found in peoples in a different ESS.

Evolutionary forces themselves vary according to what ESS you’re in. Which ESS you’re in may be the most fundamental ethnic fact, and explain the most profound ethnic behavioral differences

Look, everyone is always looking for the secret principles that underlie human society and history, some algebra that takes mounds of historical and archaeological data – the stuff that happens – and explains it in some compact way, lets us understand it, just as continental drift made a comprehensible story out of geology. On second thought, ‘everyone’ mean that smallish fraction of researchers that are slaves of curiosity…

This approach isn’t going to explain everything – nothing will. But it might explain a lot, which would make it a hell of a lot more valuable than modern sociology or cultural anthropology. I would hope that an analysis of this sort might help explain fundamental long-term flavor difference between different human societies, differences in life-history strategies especially (dads versus cads, etc). If we get particularly lucky, maybe we’ll have some notions of why the Mayans got bored with civilization, why Chinese kids are passive at birth while European and African kids are feisty. We’ll see.

Of course we could be wrong. It’s going to have be tested and checked: it’s not magic. It is based on the realization that the sort of morphs and game-theoretic balances we see in some nonhuman species are if anything more likely to occur in humans, because our societies are so complex, because the effectiveness of a course of action so often depends on the psychologies of other individuals – that and the obvious fact that people are not the same everywhere.

Why Information Grows – Paul Romer
thinking like a physicist:

The key element in thinking like a physicist is being willing to push simultaneously to extreme levels of abstraction and specificity. This sounds paradoxical until you see it in action. Then it seems obvious. Abstraction means that you strip away inessential detail. Specificity means that you take very seriously the things that remain.

Commenter Gwen on the blog Infoproc hints at a possible neurological basis for this phenomenon, stating that “one bit of speculation I have: the neuroimaging studies seem to consistently point towards efficiency of global connectivity rather than efficiency or other traits of individual regions; you could interpret this as a general factor across a wide battery of tasks because they are all hindered to a greater or lesser degree by simply difficulties in coordination while performing the task; so perhaps what causes Spearman is global connectivity becoming around as efficient as possible and no longer a bottleneck for most tasks, and instead individual brain regions start dominating additional performance improvements. So up to a certain level of global communication efficiency, there is a general intelligence factor but then specific abilities like spatial vs verbal come apart and cease to have common bottlenecks and brain tilts manifest themselves much more clearly.” [10] This certainly seem plausible enough. Let’s hope that those far smarter than ourselves will slowly get to the bottom of these matters over the coming decades.

...

My main prediction here then is that based on HBD, I don’t expect China or East Asia to rival the Anglosphere in the life sciences and medicine or other verbally loaded scientific fields. Perhaps China can mirror Japan in developing pockets of strengths in various areas of the life sciences. Given its significantly larger population, this might indeed translate into non-trivial high-end output in the fields of biology and biomedicine. The core strengths of East Asian countries though, as science in the region matures, will lie primarily in quantitative areas such as physics or chemistry, and this is where I predict the region will shine in the coming years. China’s recent forays into quantum cryptography provide one such example. [40]

...

In fact, as anyone who’s been paying attention has noticed, modern day tech is essentially a California and East Asian affair, with the former focused on software and the latter more so on hardware. American companies dominate in the realm of internet infrastructure and platforms, while East Asia is predominant in consumer electronics hardware, although as noted, China does have its own versions of general purpose tech giants in companies like Baidu, Alibaba, and Tencent. By contrast, Europe today has relatively few well known tech companies apart from some successful apps such as Spotify or Skype and entities such as Nokia or Ericsson. [24] It used to have more established technology companies back in the day, but the onslaught of competition from the US and East Asia put a huge dent in Europe’s technology industry.

...

Although many will point to institutional factors such as China or the United States enjoying large, unfragmented markets to explain the decline of European tech, I actually want to offer a more HBD oriented explanation not only for why Europe seems to lag in technology and engineering relative to America and East Asia, but also for why tech in the United States is skewed towards software, while tech in East Asia is skewed towards hardware. I believe that the various phenomenon described above can all be explained by one common underlying mechanism, namely the math/verbal split. Simply put, if you’re really good at math, you gravitate towards hardware. If your skills are more verbally inclined, you gravitate towards software. In general, your chances of working in engineering and technology are greatly bolstered by being spatially and quantitatively adept.

...

If my assertions here are correct, I predict that over the coming decades, we’ll increasingly see different groups of people specialize in areas where they’re most proficient at. This means that East Asians and East Asian societies will be characterized by a skew towards quantitative STEM fields such as physics, chemistry, and engineering and towards hardware and high-tech manufacturing, while Western societies will be characterized by a skew towards the biological sciences and medicine, social sciences, humanities, and software and services. [41] Likewise, India also appears to be a country whose strengths lie more in software and services as opposed to hardware and manufacturing. My fundamental thesis is that all of this is ultimately a reflection of underlying HBD, in particular the math/verbal split. I believe this is the crucial insight lacking in the analyses others offer.

Sailer In TakiMag: What Does the Deep History of China and India Tell Us About Their Futures?: http://takimag.com/article/a_pair_of_giants_steve_sailer/print#axzz5BHqRM5nD
In an age of postmodern postnationalism that worships diversity, China is old-fashioned. It’s homogeneous, nationalist, and modernist. China seems to have utilitarian 1950s values.

For example, Chinese higher education isn’t yet competitive on the world stage, but China appears to be doing a decent job of educating the masses in the basics. High Chinese scores on the international PISA test for 15-year-olds shouldn’t be taken at face value, but it’s likely that China is approaching first-world norms in providing equality of opportunity through adequate schooling.

Due to censorship and language barriers, Chinese individuals aren’t well represented in English-language cyberspace. Yet in real life, the Chinese build things, such as bridges that don’t fall down, and they make stuff, employing tens of millions of proletarians in their factories.

The Chinese seem, on average, to be good with their hands, which is something that often makes American intellectuals vaguely uncomfortable. But at least the Chinese proles are over there merely manufacturing things cheaply, so American thinkers don’t resent them as much as they do American tradesmen.

Much of the class hatred in America stems from the suspicions of the intelligentsia that plumbers and mechanics are using their voodoo cognitive ability of staring at 3-D physical objects and somehow understanding why they are broken to overcharge them for repairs. Thus it’s only fair, America’s white-collar managers assume, that they export factory jobs to lower-paid China so that they can afford to throw manufactured junk away when it breaks and buy new junk rather than have to subject themselves to the humiliation of admitting to educationally inferior American repairmen that they don’t understand what is wrong with their own gizmos.

...

This Chinese lack of diversity is out of style, and yet it seems to make it easier for the Chinese to get things done.

In contrast, India appears more congenial to current-year thinkers. India seems postmodern and postnationalist, although it might be more accurately called premodern and prenationalist.

...

Another feature that makes our commentariat comfortable with India is that Indians don’t seem to be all that mechanically facile, perhaps especially not the priestly Brahmin caste, with whom Western intellectuals primarily interact.

And the Indians tend to be more verbally agile than the Chinese and more adept at the kind of high-level abstract thinking required by modern computer science, law, and soft major academia. Thousands of years of Brahmin speculations didn’t do much for India’s prosperity, but somehow have prepared Indians to make fortunes in 21st-century America.

- Study used two moderately large American community samples.
- Verbal and not nonverbal ability drives relationship between ability and ideology.
- Ideology and ability appear more related when ability assessed professionally.
- Self-administered or nonverbal ability measures will underestimate this relationship.

Every once in a while I realize something with my conscious mind that I’ve understood implicitly for a long time. Such a thing happened to me yesterday, while reading a post on Stalin, by Amritas. It is this:

S = P + E

Social Status equals Political Capital plus Economic Capital

...

Here’s an example of its explanatory power: If we assume that a major human drive is to maximize S, we can predict that people with high P will attempt to minimize the value of E (since S-maximization is a zero-sum game). And so we see. Throughout history there has been an attempt to ennoble P while stigmatizing E. Conversely, throughout history, people with high E use it to acquire P. Thus, in today’s society we see that socially adept people, who have inborn P skills, tend to favor socialism or big government – where their skills are most valuable, while economically productive people are often frustrated by the fact that their concrete contribution to society is deplored.

Now, you might ask yourself why the reverse isn’t true, why people with high P don’t use it to acquire E, while people with high E don’t attempt to stigmatize P? Well, I think that is true. But, while the equation is mathematically symmetrical, the nature of P-talent and E-talent is not. P-talent can be used to acquire E from the E-adept, but the E-adept are no match for the P-adept in the attempt to stigmatize P. Furthermore, P is endogenous to the system, while E is exogenous. In other words, the P-adept have the ability to manipulate the system itself to make P-talent more valuable in acquiring E, while the E-adept have no ability to manipulate the external environment to make E-talent more valuable in acquiring P.

...

1. All institutions will tend to be dominated by the P-adept
2. All institutions that have no in-built exogenous criteria for measuring its members’ status will inevitably be dominated by the P-adept
3. Universities will inevitably be dominated by the P-adept
4. Within a university, humanities and social sciences will be more dominated by the P-adept than … [more]
