The Virus Stats that Cost Everyone a Lot

By Martin Cohen
This is a post about statistics. Not that I’m actually a great mathematician, let alone a statistician, but I do at least appreciate that the power of numbers to influence debates. And a debate in particular where statistics have been thrown around since the beginning of the Covid one. 

So, travel with me back nearly two years to the origins, and take a second look at some key metrics that have been tossed about ever since. One problematic measure has been the “Case Fatality Rate”. This was officially put by the United Nations at just under 1%, making Covid a very deadly virus.

The bit we can agree on is the definition. The CFR is the number of deaths from Covid divided by the number of “confirmed cases”.

The problem is that deciding who actually died “from Covid” is very murky. A typical report is that 95% of people dying from Covid have other co-morbidities. This means that they may actually have died from these rather than from Covid. The issue is exacerbated when you see that the typical age of someone dying “from Covid” is pretty much the age at which anyone dies.

So the numerator part of this crucial figure is HIGHLY debatable - and the denominator part, the number of cases is too. For starters, one problem is that what you, me and Joe Public understand as “a confirmed case” is someone who has symptoms and goes to hospital and is tested and found to have the virus. That would all make sense. But in fact, a case is simply someone who has the virus. And again, it is agreed that the great majority of people who encounter the virus never have any symptoms. These people are often not counted. This is why the number of cases a country has depends essentially on how much testing the government chooses to do.

To make matters worse, it depends on the criteria used for the test. The benchmark test, the so called PCR (polymerase chain reaction ) test, considered “the gold standard” for detecting Covid. The test amplifies genetic matter from the virus in cycles; the more cycles used, the greater the amount of virus, or viral load, found in the sample. Crucial to the test, then, is how many cycles are used -and that, perhaps surprisingly, is not a medical decision but a political one. In Europe, for example, The European Centre for Disease Prevention and Control does not recommend a specific maximum amplification cycle threshold for PCR tests. However, it does recommend that if the values are high, e.g. > 35, “repeated testing should be considered”. In other words, it recognises the results are unsafe.

Yet that decision on the number of cycles is not even communicated when a “positive test” is returned. As Angela Rasmussen, a virologist at Columbia University in New York told the New York Times, “It’s just kind of mind-blowing to me that people are not recording the C.T. values from all these tests — that they’re just returning a positive or a negative.”

Ultimately, there is no standard cycle threshold value that is agreed upon internationally. The U.S. Food and Drug Administration currently gives laboratory manufacturers autonomy in determining how many cycles are needed to determine whether a sample is positive or negative.

How accurate the test is matters, because everyone admitted to hospital, for whatever reason - maybe they had a heart attack - is routinely tested for Covid. If they are considered positive, and later on die, they will be counted as a Covid fatality, as “dying within 21 days of a positive test”.

So that’s three rather big question-marks lurking in the Covid data. But the next one, I think, is worse. This statistic purports to show vaccines save people from the worst effects of the disease.

It’s the statistic that led the CDC in the US to say:
“COVID-19 vaccines are highly effective at preventing severe COVID-19 and death.”
And you can read that in all the papers, in all the fact-checkers, and so you “might” think it must be true. However, statisticians at Queen Mary College in London, looked at the UK data (which is representative of other countries too) and concluded:
“Official mortality data for England suggest systematic miscategorisation of vaccine status and uncertain effectiveness of C19 vaccination”
They noticed that the official statistics showed that, following vaccination, there was a sudden surge in the numbers of UNVACCINATED people dying. The so-called ‘healthy vaccine’ effect. A less cheery explanation was that vaccines might actually be killing people - but if the deaths occurred within 21 days, as most side-effects do - being classified as deaths of “unvaccinated”.

This is a possibility, and adverse effects databases like the European EudraVigilance database and US VAERs ones currently report alarmingly high numbers, in apparently compelling detail – however the miscategorisation does not need to mean that vaccines are killing a lot of elderly people. Rather, fragile people are prioritised for vaccination, and thus skew the figures. However, by grouping vulnerable people together statistically to be vaxed and then … calling this group the unvaccinated, the authorities have very conveniently created an apparently miraculous positive effect for vaccines. That it is not really there is indicated that the positive effect – “vaccines save lives” - is not only for Covid but for ALL CAUSE mortality!

This is known. Yet far from accepting the statistics mislead, governments and drug companies surmise that the treatments may have unexpected general positive effects.

In reality, the statistical anomaly is large because in countries like the UK, the NHS Guidelines explicitly state that the most critically ill people are the ones who must be prioritised for vaccination in each age group.

Let me try to sum it all up in three sentences! Vaccine data shows most of the advantage from the jab in the first few months. Because Covid vaccination programs prioritise very ill people, a significant number of whom die in the following 21 days - not from the vax necessarily, just because they were, well, vulnerable. Whatever the reason, again under the official guidelines, these deaths are classed as ‘unvaccinated’, creating the ‘bad news’ for the unvaccinated and the amazing, parallel, health boost for those who are.

So there you have it. Some examples of how duff statistics alone, not anything more secretive let alone worrying, could have created a Ten Trillion Dollar “pandemic” that maybe never was. Worse still, they could have led to policies that really have been killing people.

A Modest Proposal for Science

Posted by Andrew Porter

For several centuries, modern science has banked on and prided itself in ‘the scientific method’. This scheme of hypothesis and experiment has been useful and effective in countering superstition. Discoveries of all sorts have been made and verified, from the circumference of orbits to the range of elements to the function of organelles and proteins in a cell. Confirmation from experiment seems like a clear way to separate fact from fiction. But it is crucial to note that the scientific method also fails.

Recent conundrums of physicality, consciousness, entanglement, dark matter, and the nature of natural laws have spurred many to rethink assumptions and even findings. Our search for what is real and natural needs a new method, one that is in keeping with the natural facts themselves – natural facts not as reduced or squeezed or contorted by the scientific method, but as their own holistic selves. The method of approach and apprehending that seems to offer the most promising advance is that which consists of a whole person in a whole natural environment.

Why do I emphasise wholeness? Because facts shrink away at the first sign of partiality or limited agenda. Truth, conversely, tends to open itself to an apt seeker, to a method that goes whole at a host of levels. Nature tends to recognise her own, it seems.

Kristin Coyne, in an article called ‘Science on the Edge’ in the February 17, 2017 issue of the magazine, Fields: Science, Discovery & Magnetism, writes:
‘At the dividing line between two things, there’s often no hard line at all. Rather, there’s a system, phenomenon or region rich in diversity or novel behavior – something entirely different from the two things that created it.’
She offers various examples of the same: fringe physics, borderline biology, and crossover chemistry. Such ‘science on the edge’ is one aspect of the changes typical science is undergoing. Other researchers in areas such as telepathy and theoretical physics are pushing the bounds of science while arguing that it certainly is science, just a deeper form.

This suggested new method, that would largely overturn contemporary science, would measure, as it were, by that of nature’s measurements: it is anti-reductionist; it is synthetic more than analytic. As we are learning, it may not be too much to say that one has to be the facts to know the facts, to be a synergy of ‘observer’ and ‘observed’ at all levels. The knowledge gleaned from wholeness is like a star’s heat and light understood, not just the hydrogen and helium involved.

This idea of the ‘scientist’ in tune with nature in a thorough way would be the human equivalent of a goshawk whose instincts are a portion of Earth-wide wildness. No disjunct with results that turn self-referential and untrue. If one is studying an ecosystem, for instance, he or she, or his or her team, must, by the requirements of nature, be of the same stuff and of the same conceptions as the individualities, relations, and wholes of that ecosystem. So much more of the actuality reveals itself to the sympathetic, of-a-piece ‘observer’. If we ignore or shunt aside the question of what is a whole person, how can we ever expect to discern the deeper reality of nature?

It seems to hold true that the more receptive the subject is to the essence and character of the object, the better it is understood. Who knows one’s dog better: a sympathetic owner or an objective voice? If the dog is sick, perhaps the latter, but all the time the dog is exuberantly healthy, the former is the one who comprehends.

The goal, of course, is to elucidate facts, to unite in some meaningful way with reality. Delusion is all too easy, and partial truths sustain centuries of institutions, positions, governments, and cultures. Modern science started out as reactionary in the sense of being hostile to things like superstition or intuition or revelation. It substituted experiment and observation, keeping the studied apart from those who studied. This is fine for shallow comprehension, but it only gets you so far. It obscures another possibility, that is somewhat similar to the communion and connection between the quantum realm and the macro world.

I suggest that deep facts only reveal themselves to a person metamorphosed, as it were, into ways of being in keeping with the parts or portions of nature studied. All nature may be of this type, open to human comprehension only as that comprehension is within a whole person. What a complete person is and what a fullness of nature is might not only be a philosopher’s job, but the focus of science itself, re-trained to benefit from its transformed method.

The hint in current puzzlements is that science in the 21st century and beyond may benefit significantly by re-crafting itself. A transformed method might yield deeper or actual knowledge. That is, knowing as opposed to seeming to know, may require a new approach.

Jacob Needleman and David Applebaum wrote, ‘Unless scientific progress is balanced by another kind of enquiry, it will inevitably become an instrument of self-destruction.’

The ‘objective’ revolution need not be the last. In today’s world, we have the ball-and-chain of modern scientific ways and even scientism weighting our thinking; it would be good to free ourselves from this. But we are confused. About what of objectivity is liberating or limiting, and what of subjectivity is useful or obfuscatory.

Homeopaths, Holocaust Deniers and 'Philosophers of Science'

On January 20, 2010, at 10:23 (Oxford time, we may suppose), thousands of brilliant minds tried to prove, by guzzling homeopathy pills, that homeopathic remedies could not kill people, and thus that homeopathy doesn't work (and that "there's nothing in it"). A magnificient demonstration of public adherence to the scientific method!
Reposted and updated from Pi Alpha. Edited by Martin Cohen with original research by Perig Gouanvic


“The misrepresentations of history presented by Holocaust deniers and other pseudo-historians are very similar in nature to the misrepresentations of natural science promoted by creationists and homeopaths. ... we find a wide variety of movements and doctrines, such as creationism, astrology, homeopathy, and Holocaust denialism that are in conflict with results and methods that are generally accepted in the community of knowledge disciplines. ”

- Stanford Encyclopedia of Philosophy


The Mass Suicide of Homeopathy Skeptics

Almost all of the systematic reviews in conventional journals start on a skeptical note. Indeed, nine out of ten of the articles begin with a statement that questions the scientific plausibility of homeopathy. Some of the articles use relatively strong language to make the point. For example, one by ‘Ernst and Pittler’ suggests that it is the use of ‘highly diluted material that overtly flies in the face of science and has caused homeopathy to be regarded as placebo therapy at best and quackery at worst’.

But to get a good sense of what the masses, including those who make up ‘the scientific consensus’, really think, Wikipedia is a passable indicator. Wikipedians, amongst them, in such articles, we find watchdogs of ‘reason’, including various hired professionals from the ‘Public Understanding of Science’ (and their trusted mercenaries) love to indulge in this dusty old strawman argument:
‘a 12C [homeopathic] solution is equivalent to a 'pinch of salt in both the North and South Atlantic Oceans'... One third of a drop of some original substance diluted into all the water on earth would produce a remedy with a concentration of about 13C.’
This is a stunning demonstration of the lack of intelligence not only of the ‘scientific consensus’, but of the democratic process of knowledge itself. And leading the process is Wikipedia, which turns donkeys into horses on a daily basis, as Socrates would say, while in the background is the poor state of debate between the Orthodoxy and the scientists and philosophers who are trying to make sense of homeopathy. Hahnemann spoke about a ‘forc’ that remained after dilutions and succussions, but pseudoskeptics have kept making the same strawman argument for the last 200 years.

The reality is that Hahnemann wrote a great deal and never shied away from philosophical questions. He argues:
‘A substance divided into ever so many parts must still contain in its smallest conceivable parts always some of this substance, and that the smallest conceivable part does not cease to be some of this substance and cannot possibly become nothing; - let them, if they are capable of being taught, hear from natural philosophers that there are enormously, powerful things (forces) which are perfectly destitute of weight.’
You may not agree, but it is not foolish stuff. Indeed, these days, the ‘homeopathic force’, for instance, could be described in a context of systems biology.

According to Ilya Prigogine, a Russian-born Belgian chemist best known for his definition of dissipative structures ‘and their role in thermodynamic systems far from equilibrium’(work that led him being awarded the Nobel Prize in Chemistry in 1977), in the domain of deterministic physics, all processes are time-reversible, meaning that they can proceed backward as well as forward through time. As Prigogine explains, determinism is fundamentally a denial of the arrow of time. With no arrow of time, there is no longer a privileged moment known as the ‘present’, which follows a determined ‘past’ and precedes an undetermined ‘future’. Instead, all of time is simply a given, with the future just as determined as the past. With irreversibility, the arrow of time is reintroduced to physics. Prigogine notes numerous examples of irreversibility, including diffusion, radioactive decay, solar radiation, weather and the emergence and evolution of life.

This applies especially well to homeopathy. Orthodox scientists evaluate homeopathy through the lens of the results (it’s only water/alcohol!) and tirelessly calculate oceanographic metaphors to deride what they believe is homeopathy, oblivious of the fact that dilution is conceived as a process leading to a change in the way the molecules of the solvent behave together — a change in the structure of water and a concurrent change in the forces likely to make these structures possible.


Brian Josephson, Nobel laureate of physics, has commented on a typical debunking exercise made by the New Scientist journal that:
‘criticisms [of homeopathy] centred around the vanishingly small number of solute molecules present in a solution after it has been repeatedly diluted are beside the point, since advocates of homeopathic remedies attribute their effects not to molecules present in the water, but to modifications of the water's structure. Simple-minded analysis may suggest that water, being a fluid, cannot have a structure of the kind that such a picture would demand. But cases such as that of liquid crystals, which while flowing like an ordinary fluid can maintain an ordered structure over macroscopic distances, show the limitations of such ways of thinking. There have not, to the best of my knowledge, been any refutations of homeopathy that remain valid after this particular point is taken into account.’
The particular homeopathic claim that water can ‘remember’ substances with which it has been in contact, and that such memory might be mediated by hydrogen bonds has also been criticised, typically on theoretical grounds. Many such arguments involve the short duration of individual hydrogen bonds in liquid water ( which is about a picosecond).

However, it is not to be assumed that the mesoscale structure of water must change on the same time scale. For example, in ice, hydrogen bonds are also very shortlived but an ice sculpture can ‘remember’ its shape over extended periods. (Here our essay assumes a suitbly seasonal feel - Editor.) On a smaller scale, cation hydrates are commonly described with particular structure (for example,  the octahedral Na+(H2O)6 ion) even though the individual water molecules making up such structures have very brief residence times (measured in microseconds).

Such arguments ignore the fact that the behaviour of a large population of water molecules may be retained even if that of individual molecules is constantly changing, just as a wave can cross an ocean, remaining a wave although its molecular content is continuously changing.

Evidence denying the long life of water clusters is mostly based on computer simulations but these cover only nanoseconds of simulated time. Such short periods are insufficient to show longer temporal relationships, for example those produced by oscillating reactions. They also involve relatively few water molecules and small (nanometre) dimensions, insufficient to show mesoscale (micron) effects. In short, they use models of the water molecule whose predictions correspond poorly to the real properties of water.

Certain 'memory' effects in water are well established and uncontroversial: for instance the formation of clathrate hydrates from aqueous solutions whereby previously frozen clathrates within the solution, when subsequently melted, predispose later to more rapid clathrate formation. This is explained by the presence of nanobubbles, extended chain silicates or induced clathrate initiators.

Can a homeopathic remedy work if it contains none of the original curative substance?

John Dalton (1776 - 1844) was able to estimate relative atomic masses of various molecules, the smallest unit that a chemical can exist in without losing its identity. His values were soon improved by Amadeo Avogadro (1776 - 1856), in 1811. Avogadro made the very important proposal that the volume of a gas (strictly, of an ideal gas ) is proportional to the number of atoms or molecules that are present. Hence, the relative molecular mass of a gas can be calculated from the mass of a sample of known volume. BUT neither Avogadro nor Dalton knew how many molecules there were in a given mass of a substance.  This is historically significant because it means that, although Hahnemann realised that there was a limit to the dilutions that could be used, he had no way of knowing what that limit was. An historical curiousity - or confirmation of the importance of the homeopathic principle? - is the fact that Darwin tested out ultrahigh dilutions on carnivorous plants. In Insectivorous Plants (1875) he writes:
‘The reader will best realize this degree of dilution by remembering that 5,000 ounces would more than fill a thirty-one gallon cask [barrel]; and that to this large body of water one grain of the salt was added; only half a drachm, or thirty minims, of the solution being poured over a leaf. Yet this amount sufficed to cause the inflection of almost every tentacle, and often the blade of the leaf. … My results were for a long time incredible, even to myself, and I anxiously sought for every source of error. … The observations were repeated during several years. Two of my sons, who were as incredulous as myself, compared several lots of leaves simultaneously immersed in the weaker solutions and in water, and declared that there could be no doubt about the difference in their appearance. … In fact every time that we perceive an odor, we have evidence that infinitely smaller particles act on our nerves.’
But we have to be careful; homeopathy was not the declared, explicit, subject of this text, although it may have been an underlying riddle for Darwin (we know that he visited an homeopath, out of despair about his condition, and felt better after).

In any case, in the Sixth edition of Hahnemann's Organon, which is the ‘Bible’ for practising homeopaths, Hahnmann explicitly moves beyond ‘physical’ cause and effect into the mystical world of mesmerism - or healing by the mystical agency of the so-called vital force (popular at the time and perhaps similar to the notion of chi in Chinese medicine.)
‘I find it necessary to allude here to animal magnetism, as it is termed, or rather mesmerism (as it should be called, out of gratitude to Mesmer, its first founder), which differs so much in its nature from all other therapeutic agents. 
 
This curative power, often so stupidly denied, which streams upon a patient by the contact of a well-intentioned person powerfully exerting his will, either acts homoeopathically, by the production of symptoms similar to those of the diseased state to be cured; and for this purpose a single pass made, without much exertion of the will, with the palms of the hands not too slowly from the top of the head downwards over the body to the tips of the toes, is serviceable in, for instance, uterine haemorrhages, even in the last stage when death seems approaching; or it is useful by distributing the vital force uniformly throughout the organism, when it is in abnormal excess in one part and deficient in other parts, for example, in rush of blood to the head and sleepless, anxious restlessness of weakly persons, etc., by means of a similar, single, but somewhat stronger pass; or for the immediate communication and restoration of the vital force to some one weakened part or to the whole organism, - an object that cannot be attained so certainly and with so little interference with the other medicinal treatment by any other agent besides mesmerism.’
According to the German newspaper Bild, a seventh edition of the Organon was recently unearthed in his native Germany, and this reveals that the doctor had continued his work on replacing dilutions with mesmerism and had completed experiments on the resuscitation of dead dogs. Alas, as the newspaper puts it, ‘He died shortly afterwards.’

The bottom line is that homeopathic dilution has not been shown o work, but nor yet has it been shown to be impossible. Some will say ‘well, you cannot prove a negative’ which may be true, but clearly the history of science is of things that people rejected as impossible becoming accepted in the light on new and more sophisticated understandings. The same could yet be said for the mystery of homeopathic dilution.

Special Investigation: Gene Therapy and the Origins of Life

The process of natural selection and survival of the fittest lies at the surface of the great molecular chronicle of gene therapy. This investigation argues  the approach will play a great use in near future- as long as  attention is paid to the very spirit of its conceptualisation.

A Special Pi Investigation into the Biochemical Mechanisms involved in Origins and the Evolution of Life - centred on the role of Gene Shuffling.

by Muneeb Faiq and PI editors
Is gene therapy - or gene shuffling as we might alternatively call it -  a product of human genius or a traditional method employed by evolution for last 3.2 billion years in order to give rise to all forms of life that the planet earth has seen? 

Indisputably, this is a very important question which has escaped attention from theoretical biologists for almost four decades (since gene therapy was conceptualised) and there seems to be almost no literature available on it. Instead, there is a general tendency to think that gene therapy is a very recent phenomenon innovated by human mind to achieve desired functioning of a gene and consequently an organism.

That notion is correct in its own right but when you look at it with a little scrutiny, you have to be drawn to the conclusion that gene therapy has been the modus operandi of the process of evolution for billions of years and it is the process of gene therapy (or gene manipulation for that matter) that has brought about the variety and complexity of life that we witness today.

This philosophical investigation will oppose the self-evident notion that the best survives (which begs the question of what the 'best' means) by emphasising that it is the shuffling, the complexity, of gene manipulations that is the real engine of evolution.

What is a philosophical problem? The irrefutable metahypothesis

By Matthew Blakeway

If we ban speculation about metahypotheses, does philosophical debate simply evaporate? 



Karl Popper explained how scientific knowledge grows in his book Conjectures and Refutations. A conjecture is a guess as to an explanation of a phenomenon. And an experiment is an attempt to refute a conjecture. Experiments can never prove a conjecture correct, but if successive experiments fail to refute it, then gradually it becomes accepted by scientists that the conjecture is the best available explanation. It is then a scientific theory. Scientists don’t like the word “conjecture” because it implies that it is merely a guess. They prefer the word “hypothesis”. Popper’s rule is that, for a hypothesis to be considered scientific, it must be empirically falsifiable.

When scientists consider a phenomenon that is truly mystifying, it seems reasonable to ask “what might a hypothesis for this look like?” At this point, scientists are hypothesising about hypotheses. Metahypothetical thinking is the first step in any scientific journey. When this produces no results, frustration gets the upper hand and they pursue the following line of reasoning: “the phenomenon is an effect, and must have a cause. But since we don’t know what that cause is, let’s give it a name ‘X’ and then speculate about its properties.” A metahypothesis is now presumed to be 'A Thing', rather than merely an idea about an idea.

The problem is the irrefutability of its existence.

Plato, Democritus and Alternative Medicine

Could the history of philosophy, and in particular the unresolved debate between Plato and Democritus, explain the present debate between alternative and conventional approaches to nature and health?


'Alternative Medicine' is defined by the Oxford English Dictionary as "any of a range of medical therapies not regarded as orthodox by the medical profession", citing chiropractic, faith healing, herbalism, homeopathy and reflexology as examples. 1 Yet a study in the New England Journal of Medicine found that over one third of people preferred alternative medicine to conventional methods, citing the medical establishment's emphasis on diagnostic testing and drug treatments that did not consider the patient's well-being and health as a whole.2 Edzard Ernst, a Professor of Complementary Medicine at the University of Exeter in the U.K puts usage even higher, saying that "about half the general population in developed countries use complementary and alternative medicine".3 And in some countries, notably China and India, what are considered 'alternative' treatments are central to government health strategies. 4 In fact, there are social and cultural dimensions to health policy as well as scientific and historical ones. Nowhere is this more apparent than in the response and acceptance of so-called 'alternative' health treatments.

BBC propaganda

BBC propaganda

An alarming insight into how the BBC operates?
 

 

  Who's Churning the BBC Machine?

 • 'How the BBC became a propaganda machine for climate change zealots 
 - as recounted by its former news frontman, Peter Sissons




Based on  the Daily Wail story which in turn drew on Peter Sissons's memoirs, with additional comments by Pi editors.

Sissons diagnoses it as 'political correctness'. Worrying about manmade climate change was an incontrovertible duty - a view also taken, for example, at the Guardian and the Times newspapers. But Sisson's writes:

'From the beginning I was unhappy at how one-sided the BBC's coverage of 
the issue was, and how much more complicated the climate system was than 
the over-simplified two-minute reports that were the stock-in-trade of 
the BBC's environment correspondents.

These, without exception, accepted the UN's assurance that 'the science 
is settled' and that human emissions of carbon dioxide threatened the 
world with catastrophic climate change. Environmental pressure groups 
could be guaranteed that their press releases, usually beginning with 
the words 'scientists say..'. would get on air unchallenged.

On one occasion, an MP used BBC airtime to link climate change doubters 
with perverts and holocaust deniers, and his famous interviewer didn't 
bat an eyelid.

On another occasion, after the inauguration of Barack Obama as president in 2009, the science correspondent of Newsnight actually informed viewers: 
'scientists calculate that he has just four years to save the world'. What she didn't tell viewers was that only one alarmist scientist, NASA's James Hansen, had said that.

My interest in climate change grew out of my concern for the failings of 
BBC journalism in reporting it. In my early and formative days at ITN, I 
learned that we have an obligation to report both sides of a story. It 
is not journalism if you don't. It is close to propaganda.
