Kayfabe

Kayfabe   (by Eric Weinstein link)

The sophisticated "scientific concept" with the greatest potential to enhance human understanding may be argued to come not from the halls of academe, but rather from the unlikely research environment of professional wrestling.

Evolutionary biologists Richard Alexander and Robert Trivers have recently emphasized that it is deception rather than information that often plays the decisive role in systems of selective pressures. Yet most of our thinking continues to treat deception as something of a perturbation on the exchange of pure information, leaving us unprepared to contemplate a world in which fakery may reliably crowd out the genuine. In particular, humanity's future selective pressures appear likely to remain tied to economic theory which currently uses as its central construct a market model based on assumptions of perfect information.

If we are to take selection more seriously within humans, we may fairly ask what rigorous system would be capable of tying together an altered reality of layered falsehoods in which absolutely nothing can be assumed to be as it appears. Such a system, in continuous development for more than a century, is known to exist and now supports an intricate multi-billion dollar business empire of pure hokum. It is known to wrestling's insiders as "Kayfabe". 

Because professional wrestling is a simulated sport, all competitors who face each other in the ring are actually close collaborators who must form a closed system (called "a promotion") sealed against outsiders. With external competitors generally excluded, antagonists are chosen from within the promotion and their ritualized battles are largely negotiated, choreographed, and rehearsed at a significantly decreased risk of injury or death. With outcomes predetermined under Kayfabe, betrayal in wrestling comes not from engaging in unsportsmanlike conduct, but by the surprise appearance of actual sporting behavior. Such unwelcome sportsmanship which "breaks Kayfabe" is called "shooting" to distinguish it from the expected scripted deception called "working". 

Were Kayfabe to become part of our toolkit for the twenty-first century, we would undoubtedly have an easier time understanding a world in which investigative journalism seems to have vanished and bitter corporate rivals cooperate on everything from joint ventures to lobbying efforts. Perhaps confusing battles between "freshwater" Chicago macro economists and Ivy league "Saltwater" theorists could be best understood as happening within a single "orthodox promotion" given that both groups suffered no injury from failing (equally) to predict the recent financial crisis. The decades old battle in theoretical physics over bragging rights between the "string" and "loop" camps would seem to be an even more significant example within the hard sciences of a collaborative intra-promotion rivalry given the apparent failure of both groups to produce a quantum theory of gravity. 

What makes Kayfabe remarkable is that it gives us potentially the most complete example of the general process by which a wide class of important endeavors transition from failed reality to successful fakery. While most modern sports enthusiasts are aware of wrestling's status as a pseudo sport, what few alive today remember is that it evolved out of a failed real sport (known as "catch" wrestling) which held its last honest title match early in the 20th century. Typical matches could last hours with no satisfying action, or end suddenly with crippling injuries to a promising athlete in whom much had been invested. This highlighted the close relationship between two paradoxical risks which define the category of activity which wrestling shares with other human spheres:
• A) Occasional but Extreme Peril for the participants.
• B) General: Monotony for both audience and participants.
Kayfabrication (the process of transition from reality towards Kayfabe) arises out of attempts to deliver a dependably engaging product for a mass audience while removing the unpredictable upheavals that imperil participants. As such Kayfabrication is a dependable feature of many of our most important systems which share the above two characteristics such as war, finance, love, politics and science.

Importantly, Kayfabe also seems to have discovered the limits of how much disbelief the human mind is capable of successfully suspending before fantasy and reality become fully conflated. Wrestling's system of lies has recently become so intricate that wrestlers have occasionally found themselves engaging in real life adultery following exactly behind the introduction of a fictitious adulterous plot twist in a Kayfabe back-story. Eventually, even Kayfabe itself became a victim of its own success as it grew to a level of deceit that could not be maintained when the wrestling world collided with outside regulators exercising oversight over major sporting events.

At the point Kayfabe was forced to own up to the fact that professional wrestling contained no sport whatsoever, it did more than avoid being regulated and taxed into oblivion. Wrestling discovered the unthinkable: its audience did not seem to require even a thin veneer of realism. Professional wrestling had come full circle to its honest origins by at last moving the responsibility for deception off of the shoulders of the performers and into the willing minds of the audience.

Kayfabe, it appears, is a dish best served client-side.

Detachment


I often remind people of the word "orrery". An orrery is a model that works perfectly well, its use results in highly accurate predictions… within bounds of application. The difference between an orrery and a theory, is that a orrery is not causally supported by foundational understandings of the universe. An orrery is internally consistent, but externally disassociated. The classic orrery of course is the painted balls on bent wires articulating around a set of gears and cams on spindles that classical scholars produced to explain the motion the sun and moon and other celestial bodies. Obviously, such models predict the behavior of the system, but don't come near explaining the causal hierarchy that leads to behavior. planets and stars aren't hooked to huge rods. It is theoretically possible to concoct an infinite number of orreries, causally false models, to explain and model any one system or domain. Randall Lee Reetz

Ontology & Epistemology

I tend to gravitate around "the Map is not the Territory" concept in the ontology/epistemology discussion. I understand «territory» as the event generator, aka reality. We are only able to measure events indirectly using our senses and tech (events with no effects are non-existent for all purposes). The 'map' is a tangled web of shared and private beliefs that we, Humanity, build and maintain for centuries. The «Map» is the meaning generator (I'm dropping the guillemets now).

The terms objective/subjective imho only make sense in the Map. Objective beliefs are those not dependent of personal mind states, and those dependent are subjective (this is more like a spectrum than a boolean feature, but let's keep it simple). Beliefs not dependent of private or social features (even if they are known just because of specific historical contexts) and which are known using logic/evidence/reason are (more) objective like Math. This does not mean that objective beliefs are necessarily 'true' (it depends on the semantics of the word 'true') but they are not, or should not be, dependent of persons X's or Y's state of mind. This also does not mean that objective beliefs are necessarily better than subjective ones (that requires a value judgement which is context-dependent). Anyway, this is why I think that, say, my liking of ice-cream is subjective. That is a private belief that would not exist if I would not exist. It depends of my current mind state. On the other hand, the theory of evolution by natural selection or the Central Limit Theorem are beliefs that do not depend on any person's mind. But, either objective or subjective, all are map denizens. Even scientific models are just that: maps; not intrinsically true or false, just more or less adequate to the known relevant evidence and current knowledge. 

However this way of classifying beliefs is just one way not the way. Thinking about the divide between public or private beliefs is as important as seeing them as objective or subjective (Ethics and Politics seems a much more interesting and important subject that Ontology and Epistemology but that's my perspective). 

One more thing: in a subtle way, every belief belongs to the Territory -- human beliefs are caused by certain neuro-electric impulses, and those are measurable events -- which is a trivial fact and not that interesting (even if it is important, because it protects this model of ontology against the charge of dualism, the Map is not independent of the Territory). The meaning of those brain impulses only makes sense in the Map. Without humans -- the makers and keepers of the Human Map -- the only thing that would exist would be the physical phenomena that we label with words and inject with meaning. Without a 'Map' there would be no stars, no colors or sounds, no art or philosophy or love. There would only exist 'meaningless indifferent stuff' (for lack of better words).

Percepção e Cultura


Os japoneses usam a palavra 'azul' descrever a luz verde dos semáforos. Esta particularidade deriva de, antes do período moderno, existir apenas uma palavra para os tons de azul e verde (ao). Por volta do século XI surgiu na literatura uma outra palavra para designar um tom esverdeado de azul (midori). Este tipo de conceito é comum também em português (e.g., escarlate é um tom de vermelho, mas não é normalmente considerado uma cor independente). Já no século XX, em parte por influencias culturais externas, midori foi promovida a cor, apesar de ainda restarem cicatrizes antigas como a designação da cor dos referidos semáforos. Esta falta de distinção ocorre noutras linguagens. Na Bíblia Hebraica ou na Odisseia de Homero, não existe palavra para azul. [1]


O mapa das cores é um espaço contínuo de tonalidades, e as cores são um sistema discreto de classificação. Existe sempre uma perda nesta discretização que, por sua vez, é cultural e historicamente contingente mas também dependente da forma como funcionam os nossos olhos e o nosso cérebro. Mas qual a influência da cultura? Brent Berlin and Paul Kay, nos anos 1960, procuraram regras universais que regiam como as culturas lidam com o espaço cromático. Eles descobriram que existem entre 2 e 11 nomes para as cores principais. E que quando existiam X cores, estas tendiam a ser as mesmas.
Segundo o diagrama, se uma cultura usa apenas duas cores, estas serão o branco e o preto (claro/escuro). Se uma cultura usa três cores, a terceira tendencialmente é o vermelho. E assim sucessivamente. Quando se chega à sexta cor é o momento em que o azul se separa do verde. Das 98 línguas estudadas, 92 seguiam este padrão.


E em português? É curioso como temos nomes para vários tons relacionados com vermelho (escarlate, laranja, púrpura, violeta, roxo, magenta) mas quase nada para o verde. No entanto, se olharmos para a seguinte foto dificilmente podemos afirmar que predomina uma única cor (verde) quando realmente há vários tons de verde e que apenas nos falta vocabulário para os nomear.


A cor é uma noção subjectiva, não existe 'lá fora', tendo apenas presença na imagem que o cérebro constrói para mapear o que o rodeia. O mesmo se passa com sons, sabores, a sensação de calor e outra informação recolhida pelos nossos vários sentidos. O vocabulário para cor, porém, ajuda-nos a processar de forma distinta uma parte do 'nosso' mundo, o umwelt (a selecção natural tende a eliminar os sentidos menos úteis em ralação à região habitada pela respectiva população). Um conjunto rico de palavras para cor permite uma maior qualidade da percepção, uma recolha mais fina da informação disponível. A foto acima seria mais rica se a língua portuguesa tivesse dez palavras distintas para verde. E a cor é apenas uma dimensão possível. Um botânico ou um jardineiro retirariam ainda mais detalhe da mesma foto. Àparte das nossas limitações cognitivas, uma cultura e uma língua mais ricas conceptualmente tornam a nossa visão do mundo numa experiência também ela mais rica.

Falácia de Projecção Mental

Alfred North Whitehead no seu livro Process and Reality de 1929 apresentou o que ficou conhecido como The Fallacy of Misplaced Concreteness:
neglecting the degree of abstraction involved when an actual entity is considered merely so far as it exemplifies certain categories of thought (pg.11).
Este é um aviso sobre o erro de confundir o abstracto com o concreto. Esta ideia possui várias denominações. Talvez a mais conhecida seja a de Alfred Korzybski, 'O mapa não é o território'.

A este mesmo problema E.T. Jaynes designou por Falácia de Projecção Mental. No texto seguinte Jaynes usa-o para discutir as interpretações da teoria quântica e como a confusão entre estes dois níveis -- entre ontologia e epistemologia -- pode ter estado na origem do célebre desacordo de que deus não joga aos dados entre Einstein e Bohr:

The failure of quantum theorists to distinguish in calculations between several quite different meanings of 'probability', between expectation values and actual values, makes us do things that don't need to be done; and to fail to do things that do need to be done. We fail to distinguish in our verbiage between prediction and measurement. For example, the famous vague phrases: 'It is impossible to specify...'; or 'It is impossible to define...' can be interpreted equally well as statements about prediction or statements about measurement. Thus the demonstrably correct statement that the present formalism cannot predict something becomes perverted into the logically unjustified (and almost certainly false) claim that the experimentalist cannot measure it!

We routinely commit the Mind Projection Fallacy: supposing that creations of our own imagination are real properties of Nature, or that our own ignorance signifies some indecision on the part of Nature. It is then impossible to agree on the proper place of information in physics. This muddying up of the distinction between reality and our knowledge of reality is carried to the point where we find some otherwise rational physicists, on the basis of the Bell inequality experiments, asserting the objective reality of probabilities, while denying the objective reality of atoms! These sloppy habits of language have tricked us into mystical, pre-scientific standards of logic, and leave the meaning of any QM result ambiguous. Yet from decades of trial-and-error we have managed to learn how to calculate with enough art and tact so that we come out with the right numbers!

The main suggestion we wish to make is that how we look at basic probability theory has deep implications for the Bohr-Einstein positions. Only since 1988 has it appeared to the writer that we might be able finally to resolve these matters in the happiest way imaginable: a reconciliation of the views of Bohr and Einstein in which we can see that they were both right in the essentials, but just thinking on different levels.

Einstein's thinking is always on the ontological level traditional in physics; trying to describe the realities of Nature. Bohr's thinking is always on the epistemological level, describing not reality but only our information about reality. The peculiar flavor of his language arises from the absence of all words with any ontological import. J. C. Polkinghorne (1989, pp. 78,79) came independently to this same conclusion about the reason why physicists have such difficulty in reading Bohr. He quotes Bohr as saying:
"There is no quantum world. There is only an abstract quantum physical description. It is wrong to think that the task of physics is to find out how nature is. Physics concerns what we can say about nature."
[...] Bohr would chide both Wigner and Oppenheimer for asking ontological questions, which he held to be illegitimate. Those who, like Einstein (and, up until recently, the present writer) tried to read ontological meaning into Bohr's statements, were quite unable to comprehend his message. This applies not only to his critics but equally to his disciples, who undoubtedly embarrassed Bohr considerably by offering such ontological explanations as "Instantaneous quantum jumps are real physical events." or "The variable is created by the act of measurement.", or the remark of Pauli quoted above, which might be rendered loosely as "Not only are you and I ignorant of x and p; Nature herself does not know what they are."

We disagree strongly with one aspect of Bohr's quoted statement above; in our view, the existence of a real world that was not created in our imagination, and which continues to go about its business according to its own laws, independently of what humans think or do, is the primary experimental fact of all, without which there would be no point to physics or any other science.

The whole purpose of science is learn what that reality is and what its laws are. On the other hand, we can see in Bohr's statement a very important fact, not sufficiently appreciated by scientists today as a necessary part of that program to learn about reality. Any theory about reality can have no consequences testable by us unless it can also describe what humans can see and know. For example, special relativity theory implies that it is fundamentally impossible for us to have knowledge of any event that lies outside our past light cone. Although our ultimate goal is ontological, the process of achieving that goal necessarily involves the acquisition and processing of human information. This information processing aspect of science has not, in our view, been sufficiently stressed by scientists (including Einstein himself, although we do not think that he would have rejected the idea).

Although Bohr's whole way of thinking was very different from Einstein's, it does not follow that either was wrong. In the writer's present view, all of Einstein's thinking (in particular the EPR argument) remains valid today, when we take into account its ontological purpose and character. But today, when we are beginning to consider the role of information for science in general, it may be useful to note that we are finally taking a step in the epistemological direction that Bohr was trying to point out sixty years ago.

But our present QM formalism is not purely epistemological; it is a peculiar mixture describing in part realities of Nature, in part incomplete human information about Nature - all scrambled up by Heisenberg and Bohr into an omelette that nobody has seen how to unscramble. Yet we think that the unscrambling is a prerequisite for any further advance in basic physical theory. For, if we cannot separate the subjective and objective aspects of the formalism, we cannot know what we are talking about; it is just that simple. E.T. Jaynes, Probability in Quantum Theory (1996).

Modelos

"What we see of the real world is not the unvarnished real world but a model of the real world, regulated and adjusted by sense data - a model that is constructed so that it is useful for dealing with the real world. The nature of that model depends on the kind of animal we are. A flying animal needs a different kind of world model from a walking, a climbing or a swimming animal. Predators need a different kind of model from prey, even though their worlds necessarily overlap. A monkey's brain must have software capable of simulating a three-dimensional maze of branches and trunks. A water boatman's brain doesn't need 3D software, since it lives on the surface of the pond in an Edwin Abbott Flatland. [...] The point is that the nature of the model is governed by how it is to be used rather than by the sensory modality involved. [...] The general form of the mind model - as opposed to the variables that are constantly being inputted by sensory nerves - is an adaptation to the animal's way of life, no less than its wings, legs and tail are."

Guilherme de Ockham

Ockham [...] deplored the inaccuracy of the terms used in philosophy, and spent half his time trying to make them more precise. He resented the Gothic edifice of abstractions- one mounted upon the other like arches in superimposed tiers- that medieval thought had raised. We cannot find in his extant works precisely the famous formula that tradition called "Ockham's razor": entia non sunt multiplicanda praeter necessitatem - entities are not to be multiplied beyond need. But he expressed the principle in other terms again and again: pluralitas non est ponenda sine necessitate - a plurality (of entities or causes or factors) is not to be posited (or assumed) without necessity; and frustra fit per plura quod potest fieri per pauciora - it is vain to seek to accomplish or explain by assuming several entities or causes what can be explained by fewer.

The principle was not new; Aquinas had accepted it, Scotus had used it. But in Ockham's hands it became a deadly weapon, cutting away a hundred occult fancies and grandiose abstractions. Applying the principle to epistemology, Ockham judged it needless to assume, as the source and material of knowledge, anything more than sensations. From these arise memory (sensation revived), perception (sensation interpreted through memory), imagination (memories combined), anticipation (memory projected), thought (memories compared), and experience (memories interpreted through thought). "Nothing can be an object of the interior sense" (thought) "without having been an object of the exterior sense" (sensation); here is Locke's empiricism 300 years before Locke.

All that we ever perceive outside ourselves is individual entities- specific persons, places, things, actions, shapes, colors, tastes, odors, pressures, temperatures, sounds; and the words by which we denote these are "words of first intention" or primary intent, directly referring to what we interpret as external realities. By noting and abstracting the common features of similar entities so perceived, we may arrive at general or abstract ideas- man, virtue, height, sweetness, heat, music, eloquence; and the words by which we denote such abstractions are "words of second intention," referring to conceptions derived from perceptions. These "universals" are never experienced in sensation; they are termini, signa, nomina - terms, signs, names - for generalizations extremely useful (and dangerous) in thought or reason, in science, philosophy, and theology; they are not objects existing outside the mind. "Everything outside the mind is singular, numerically one."

Reason is magnificent, but its conclusions have meaning only in so far as they refer to experience- i.e., to the perception of individual entities, or the performance of individual acts; otherwise its conclusions are vain and perhaps deceptive abstractions. How much nonsense is talked or written by mistaking ideas for things, abstractions for realities! Abstract thought fulfills its function only when it leads to specific statements about specific things. From this "nominalism" Ockham moved with devastating recklessness into every field of philosophy and theology. Both metaphysics and science, he announced, are precarious generalizations, since our experience is only of individual entities in a narrowly restricted area and time; it is mere arrogance on our part to assume the universal and eternal validity of the general propositions and "natural laws" that we derive from this tiny sector of reality. Our knowledge is molded and limited by our means and ways of perceiving things (this is Kant before Kant); it is locked up in the prison of our minds, and it must not pretend to be the objective or ultimate truth about anything.

Umwelt

"In 1909, the biologist Jakob von Uexküll introduced the concept of the umwelt. He wanted a word to express a simple (but often overlooked) observation: different animals in the same ecosystem pick up on different environmental signals. In the blind and deaf world of the tick, the important signals are temperature and the odor of butyric acid. For the black ghost knifefish, it's electrical fields. For the echolocating bat, it's air-compression waves. The small subset of the world that an animal is able to detect is its umwelt. The bigger reality, whatever that might mean, is called the umgebung. The interesting part is that each organism presumably assumes its umwelt to be the entire objective reality "out there." Why would any of us stop to think that there is more beyond what we can sense? [...] a blind person does not miss vision. They do not conceive of it. Electromagnetic radiation is simply not part of their umwelt.

The more science taps into these hidden channels, the more it becomes clear that our brains are tuned to detect a shockingly small fraction of the surrounding reality. Our sensorium is enough to get by in our ecosystem, but is does not approximate the larger picture." David Eagleman [link]

Ontologia

"[...] in our view, the existence of a real world that was not created in our imagination, and which continues to go about its business according to its own laws, independently of what humans think or do, is the primary experimental fact of all, without which there would be no point to physics or any other science.

This information processing aspect of science has not, in our view, been sufficiently stressed by scientists. [...] We suggest that the proper tool for incorporating human information into science is simply probability theory and not the currently taught "random variable" kind, but the original llogical inference" kind of James Bernoulli and Laplace. For historical reasons [...] this is often called "Bayesian inference". When supplemented by the notion of information entropy, this becomes a mathematical tool for scientific reasoning of such power and versatility that we think it will require Centuries to explore all its capabilities."
