Science: Sins of Commission and of Omission

Posted by Henry Bauer on 2019/04/21

What statisticians call a type-I error is a scientific sin of commission, namely, believing something to be true that is actually wrong. A type-II error, dismissing as false something that happens to be true, could be described as a scientific sin of omission since it neglects to acknowledge a truth and thereby makes impossible policies and actions based on that truth.

The history of science is a long record of both types of errors that were progressively corrected, sooner or later; but, so far as we can know, of course, the latest correction may never be the last word, because of the interdependence of superficially different bits of science. If, for instance, general relativity were found to be flawed, or quantum mechanics, then huge swaths of physics, chemistry, and other sciences would undergo major or minor changes. And we cannot know whether general relativity or quantum mechanics are absolutely true, that they are not a type-I error — all we know is that they have worked usefully up to now. Type-II errors may always be hiding in the vast regions of research not being done, or unorthodox claims being ignored or dismissed.

During the era of modern science — that is, since about the 17th century — type-I errors included such highly consequential and far-reaching dogmas as believing that atoms are indivisible, that they are not composed of smaller units. A socially consequential type-I error in the first quarter of the 20th century was the belief that future generations would benefit if people with less desirable genetic characteristics were prevented from having children, whereby tens of thousands of Americans were forcibly sterilized as late as late as 1980.

A type-II error during the second half of the 19th century was the determined belief that claims of alleviating various ailments by electrical or magnetic treatments were nothing but pseudo-scientific scams; but that was corrected in the second half of the 20th century, when electromagnetic treatment became the standard procedure for curing certain congenital failures of bone growth and for treating certain other bone conditions as well.
Another 19th-century type-II error was the ignoring of Mendel’s laws of heredity, which were then re-discovered half a century later.
During the first half of the 20th century, a type-II error was the belief that continents could not have moved around on the globe, something also corrected in the latter part of the 20th century.


Science is held in high regard for its elucidation of a great deal about how the world works, and for many useful applications of that knowledge. But the benefits that society can gain from science are greatly restricted through widespread ignorance of and misunderstanding about the true history of science.

Regarding general social and political history, Santayana’s adage is quite well-known, that those who cannot remember the past are condemned to repeat it. That is equally true for the history of science. Since the conventional wisdom and the policy makers and so many of the pundits are ignorant of the fact that science routinely commits sins of both commission and omission, social and political policies continue to be made on the basis of so-called scientific consensus that may quite often be unsound.

In Dogmatism in Science and Medicine: How Dominant Theories Monopolize Research and Stifle the Search for Truth (McFarland 2012), evidence is cited from well-qualified and respectable sources that the mainstream consensus is flawed on quite a number of topics. Some of these are of immediate concern only to scholars and researchers, for example about the earliest settlements of the Americas, or the extinction of the dinosaurs, or the mechanism of the sense of smell. Other topics, however, are of immediate public concern, for instance a possible biological basis for schizophrenia, or the cause of Alzheimer’s disease, or the possible dangers from mercury in tooth amalgams, or the efficacy of antidepressant drugs, or the hazards posed by second-hand tobacco smoke; and perhaps above all the unproven but dogmatic belief that human-generated carbon dioxide is the prime cause of global warming and climate change, and the long-held hegemonic belief that HIV causes AIDS.

The topic of cold nuclear fusion is an instance of a possible type-II error, a sin of omission, the mainstream refusal to acknowledge the strong evidence for potentially useful applications of nuclear-atomic transformations that can occur under quite ordinary conditions.

On these, and on quite a few other matters * as well, the progress of science and the well-being of people and of societies are greatly hindered by the widespread ignorance of the fact that science always has been and will continue to be fallible,   committing sins of both omission and of commission that become corrected only at some later time — if at all.

On matters that influence public policies directly, policy-makers would be greatly helped if they could draw on historically well-informed, technically insightful, and above all impartial assessments of the contemporary mainstream consensus. A possible approach to providing such assistance would be the establishing of a Science Court; see chapter 12 in Science Is Not What You Think: How It Has Changed, Why We Can’t Trust It, How It Can Be Fixed (McFarland 2017).

      For a number of possible type-II errors, see for instance The Anomalist  and the publications of the Society for Scientific Exploration  and the Gesellschaft für Anomalistik

What everyone ought to know about global warming and climate change: an unbiased review

Posted by Henry Bauer on 2018/09/11

“What everyone knows” is that burning fossil fuels releases carbon dioxide, a “greenhouse gas” that holds in heat, warming the Earth and causing climate change, with catastrophic consequences if it isn’t stopped soon.

All official agencies, all mainstream scientific groups, say that.

What few people know is that a considerable number of experts and informed observers do not believe this AGW scenario to be correct: AGW = Anthropogenic Global Warming, global warming caused by human actions.

Those dissenting experts point out that actual data on temperature and carbon-dioxide levels, over the life of the Earth but also over the last century, show that carbon dioxide does not cause high global temperature.

But few people, again, can believe that “everyone” could be wrong about this, that “science” could be so dogmatically wrong. To form an opinion as to the relative merits of the official view and of the dissenting experts, therefore requires not only looking at the data but also at how the official view came into bring and how and why it persists. Few people want to take the time and make the effort to wade through huge amounts of writings by opposing advocates to ferret out the genuine facts and legitimate conclusions, which often calls for reading between the lines and being skeptical about everything.

My recent discovery of the Peter Ridd affair had a wonderfully beneficial consequence, learning about the writings of Don Aitkin, an Australian whose academic career included research on social and political matters as well as administrative experience that included heading a university (as Vice-Chancellor and President of the University of Canberra). Aitkin spent a decade or more reading and thinking about AGW, and summarized what he learned in a series of blogs. The last in the series, #16,  sums things up and has appropriate links to the earlier ones which concentrate on different aspects of the matter.

This offers a wonderfully convenient way for anyone to become genuinely informed about AGW, and “climate-change denialism”, and incidentally about the interaction between science and public policy. Aitkin is factually reliable and ideologically unbiased, an all-too-rare combination.

*                     *                   *                   *                   *                   *                   *                   *

My appreciation of Aitkin’s series on global warming was enhanced when he noted that the hysteria over AGW “bridges the space between science and politics in an almost unprecedented way, though it has some similarities to the ‘eugenics’ issue a hundred years ago”, something that had occurred to me also.

Another Aitkin blog-post, “A good starting position in discussions about ‘climate change’” cites the salient points made by Ben Pile at Climate Resistance:

  1. There is good scientific evidence that human activities are influencing the climate. But evidence is not fact, and neither evidence nor fact speak for themselves.
  2. The evidence for anthropogenic climate change is neither as strong nor as demanding of action as is widely claimed.
  3. Our ability to mitigate, let alone to reverse, any such change through reductions in CO2 emissions is even less certain, and may itself be harmful.
  4. The scientific consensus on climate change as widely reported inaccurately reflects the true state of scientific knowledge.
  5. How society should proceed in the face of a changing climate is the business of politics not science.
  6. Political arguments about climate change are routinely mistaken for scientific ones. Environmentalism uses science as a fig-leaf to hide an embarrassment of blind faith and bad politics.
  7. Science is increasingly expected to provide moral certainty in morally uncertain times.
  8. The IPCC is principally a political organisation.
  9. The current emphasis on mitigation strategies is impeding society’s ability to adapt to a changing climate, whatever its cause.
  10. The public remains unconvinced that mitigation is in its best interest. Few people have really bought into Environmentalism, but few people object vehemently to it. Most people are slightly irritated by it.
  11. And yet climate change policies go unchallenged by opposition parties.
  12. Environmentalism is a political ideology, yet it has never been tested democratically.
  13. Widespread disengagement from politics means that politicians have had to seek new ways to connect with the public. Exaggerated environmental concern is merely serving to provide direction for directionless politics.
  14. Environmentalism is not the reincarnation of socialism, communism or Marxism. It is being embraced by the old Right and Left alike. Similarly, climate change scepticism is not the exclusive domain of the conservative Right.
  15. Environmentalism will be worse for the poor than climate change.
  16. Environmentalism is a self-fulfilling prophecy.

*                   *                  *                     *                   *                   *                   *                   *

Aitkin is an Australian, and any connection to Australia always rekindles my appreciation for the sanctuary Australia provided the refuigee Bauers and the excellent public education from which I benefited in elementary school (Picton, NSW), at The Sydney Boys’ High School, and at the University of Sydney (moreover, in those years, at almost no cost to my parents!).
Browsing Aitkin’s writings, I came across an after-dinner speech about “Australian values”  that rings true to my own recollections and also, I think, offers some insights into the similarities and differences between American and Australian life.

What everyone knows is all too often wrong: dinosaur extinction, and much more

Posted by Henry Bauer on 2018/08/26

“What everyone knows” is all too often wrong, as I pointed out years ago, specifically about science punditry and TED talks and books;  and about climate change;  see also Who guards the guardians? Who guards science?; “Dangerous knowledge”; Dangerous knowledge II: Wrong knowledge about the history of science;  Dangerous knowledge III: Wrong knowledge about scienceDangerous knowledge IV: The vicious cycle of wrong knowledge.

Perhaps the main reason for “everyone” being wrong about so many things is that most of us take our knowledge on most or even all matters on the authority of other people, and those are all too often unwitting or witting false prophets [1]. Very few people ever bother to look for themselves into what the actual evidence is for commonly held beliefs.

I had become interested long ago in what science is and how it works, and my academic work came to focus on the “hard cases”: controversies in science, particularly the roles played by minority views and claims. So I had the time as well as the interest to dig quite deeply into the facts underlying a number of controversies, including controversies that the mainstream asserts not to be controversial. That is how I came to realize, for example, that HIV has never been proven to be the cause of AIDS, indeed has never even been proven to exist [2].

When I have the occasion to encounter someone who parrots HIV=AIDS theory, which “everyone knows”, I like to ask, “How do you know that HIV causes AIDS?”

Almost invariably the answer is, “Everyone knows that”.

Exactly. QED.

Increasingly since the 19th century, perhaps since about the early-to-middle 19th century, “science” has become the authority for most people as well as for organizations both private and public [3]. That even includes many scholars and pundits of whom one might expect better: When I had first collated HIV-test data and was giving talks about the failings of HIV/AIDS theory, a sociologist in a Science-Studies program said that I must be wrong because “tens of thousands of papers” had been published in the HIV=AIDS genre.

Until the most recent few decades, science has rarely played the role of false prophet on issues sufficiently salient as to inform public policies and actions; an exception in the first quarter of the 20th century was when misguided expert opinion about genetics and heredity led to the forced sterilization of tens of thousands of Americans [4].

Nowadays, unfortunately, science has grown so large and unwieldy as to be in many ways dysfunctional [5], so that it has given bad advice on at least two matters of considerable public importance: not only HIV/AIDS [2] but also climate change [6].

In past times and on less prominent issues whose significance rarely matters outside the scientific community itself, “science” has quite typically been wrong before it got things right. The “scientific consensus” at any given time is tentative and temporary; yet, human nature being what it is, the elite proponents of the consensus have always defended their view vigorously, including denigrating and even persecuting fellow scientists who disagree [7].

A case in point is the view that the extinction of the dinosaurs about 65 million years ago was caused by the impact on Earth of a large asteroid. A splendid recent article in the Atlantic magazine [9] gives full details of the career gauntlets run by paleontologist Gerta Keller as she has been amassing evidence against the asteroid hypothesis and for the earlier theory that the extinction was brought on by a lengthy episode of recurring intense volcanism — for perhaps 350,000 years, with particularly intense eruptions during the 100,000 or so years that coincide with the extinction. (Calculating the timing of happenings 65 million years ago is unlikely ever to permit accuracy of better than some tens of thousands of years.)

A point that seems powerful to a lay person like myself is that the dinosaur extinction was the fifth major mass extinction indicated by the fossil record, and expert opinion seems to be almost undivided that the first four extinctions had been caused by extremes of volcanic action.

The Atlantic article is also commendably accurate about contemporary science in noting how vigorously the mainstream consensus, the ruling elite, defends its point of view, how unscrupulously at least some members of that elite and their acolytes attack those who dissent; science has become riddled with knowledge monopolies.

Many examples of that sad state of affairs are at hand in a number of other fields [7]: Big-Bang cosmology, amyloid plaque as cause of Alzheimer’s disease, anti-depressant and other prescription drugs, first human settlement of the Americas, nuclear “cold fusion”, dangers of second-hand smoke, plate tectonics (“continental drift”), mechanism of the sense of smell, physiological correlates of schizophrenia, risks from mercury compounds in tooth fillings and in vaccines, possible relation between certain multiple vaccines and autism… .

It is really quite stunning, how many cases there are where “what everyone knows”, namely, the reigning scientific consensus, is questionable in light of the actual evidence, the unquestioned data.


That last is a most important thing that everyone does not know but should.

Intellectual charlatanry: TED doesn’t know how to distinguish between good science and bad science

Posted by Henry Bauer on 2018/08/07

On the Mad in America website I came across “TED betrays its own brand by flagging nutrition talk”. After following a number of links, I was led to the guidelines that the TED organization prescribes for talks eligible to be described as “TEDx” (“TEDx is an international community that organizes TED-style events anywhere and everywhere — celebrating locally-driven ideas and elevating them to a global stage. TEDx events are produced independently of TED conferences, each event curates speakers on their own, but based on TED’s format and rules.”).

Sadly, TED’s guidelines for what constitutes good science reveal abysmal ignorance:

Claims made using scientific language should:

  • Be testable experimentally.
    That would exclude all the science that relies only on observation because experimenting is not possible: astronomy, cosmology, geology, parts of biology, almost everything to do with human beings…. String theory, which presently dominates theoretical physics, is not testable experimentally, nor is cosmology’s consensus that “the universe” originated in a Big Bang about 13 billion years ago. And so on, The theory of evolution by natural selection is not testable experimentally.
    Much of what is nowadays regarded as “accepted science” or “settled science   consists just of reasonably solid observations supporting more or less plausible inductive explanations.
  • Have been published in a peer-reviewed journal (beware… there are some dodgy journals out there that seem credible, but aren’t. For further reading, here’s an article on the topic).
    The cited article does not begin to cover this issue. Peer review is not the guarantor of reliability that it is so widely taken to be (pp. 106-9 in “Science Is Not What You Think — how it has changed, why we can’t trust it, how it can be fixed”).
    Even what is published in highly regarded, long-established, peer-reviewed journals may be quite wrong. Perhaps 90% of the primary research literature in physics later turns out to have been faulty or flawed in some way (John Ziman, “Reliable Knowledge”, Cambridge University Press, 1978, p. 40). As an editor of The Lancet (Richard Horton) once put it, “Peer review … is simply a way to collect opinions from experts in the field. Peer review tells us about the acceptability, not the credibility, of a new finding”
    What peer review does very effectively is to entrench whatever the prevailing majority consensus happens to be; but the history of science is perfectly clear that any majority consensus may have a very limited useful life before it is superseded.
  • Be based on theories that are also considered credible by experts in the field.
    Thereby entrenching the possibly wrong contemporary consensus.
  • Be backed up by experiments that have generated enough data to convince other experts of its legitimacy.
    Nonsense, see detailed comments above.
  • Have proponents who are secure enough to acknowledge areas of doubt and need for further investigation.
    Proponents of a contemporary consensus are rarely so “scientific”.
  • Not fly in the face of the broad existing body of scientific knowledge.
    Again, thereby entrenching the possibly wrong contemporary consensus.
  • Be presented by a speaker who works for a university and/or has a phD [sic] or other bona fide high level scientific qualification.
    When we founded the Society for Scientific Exploration (which Wikipedia and other science-ignorant sources describe as a “fringe science” organization) it was made a requirement for full membership that applicants have a PhD or equivalent credentials. I found that rather funny, since anyone even slightly acquainted with academe or people with PhDs knows that these are absolutely no warranty of intelligence or competence or lack of kookiness.
  • Show clear respect for the scientific method and scientific thinking generally.
    “The scientific method” is a myth (“Scientific Literacy and Myth of the Scientific Method”, University of Illinois Press, 1992), and “scientific thinking” is no more easily defined than “the method” 

    Claims made using scientific language should not:

  • Be so obscure or mysterious as to be untestable
    See above re testable
  • Be considered ridiculous by credible scientists in the field
    Once more, relies on current consensus
  • Be based on experiments that can not be reproduced by others.
    For misguided views that “reproducibility” is a necessary criterion and is applied in practice, see pp. 53ff. in “Science Is Not What You Think”, book cited above
  • Be based on data that do not convincingly corroborate the experimenter’s theoretical claims.
    “Convincing” is in the eyes of the beholder
  • Come from overconfident fringe experts.
    Mainstream experts often suffer from overconfidence, and labeling someone a “fringe expert” is no easy matter
  • Use over-simplified interpretations of legitimate studies
    Simplification is a necessity in teaching and in talking to general audiences; what is “over” simplified is again in the eyes of the beholder


My detailed comments should make plain that whoever drew up these guidelines was insufficiently knowledgeable about science. That’s rather serious for an organization that says:
“Science is a big part of the TED universe, and it’s important that TEDx organizers sustain our reputation as a credible forum for sharing ideas that matter. It’s not always easy to distinguish between real science and pseudoscience…”

Indeed it isn’t, see for example Science or Pseudoscience: Magnetic Healing, Psychic Phenomena, and Other Heterodoxies (University of Illinois Press, 2001). It is likely to be impossible for an organization whose guidelines for distinguishing are ignorant rubbish, as above. And so it happened that TED “flagged” a TEDx talk about micronutrients and mental health given by a well-published PhD professor at a very respectable university:

“NOTE FROM TED: We’ve flagged this talk, which was filmed at a TEDx event, because it appears to fall outside TEDx’s curatorial guidelines. There is limited evidence to support the claims made by this speaker. Please do not look to this talk for medical advice.”

For comments on this flagging, see James Moore’s blog post “Julia Rucklidge: Nutrition, Mental Health and TED” which includes an audio of Moore’s interview with Rucklidge in which she describes the flagging (starting at about 18 minutes in the 30-minute interview).

My point here is not, however, just that the flagging was unwarranted. Anyone can learn that easily enough by checking Rucklidge’s publications and following a few other links. My point is to expose TED as practicing charlatanry, falsely claiming expertise it does not possess (“charlatan: a person falsely claiming to have a special knowledge or skill; a fraud, quack, sham, fake, impostor, hoaxer, cheat, deceiver, double-dealer, swindler, fraudster, mountebank; (informal) phony, shark, con man, con artist, scam artist, flimflammer, bunco artist, shyster, snake oil salesman; (dated) confidence man/woman”).

Not only charlatanry: sheer incompetence, and arrogant incompetence at that. Rucklidge’s TEDx talk was flagged by TED without notifying Rucklidge or the organizers of her talk. When Rucklidge learned of this, she wanted to find out the reason for the flagging — but has been unable to get any pertinent information from TED! However, TED did eventually modify the text of its flag, to:

“NOTE FROM TED: We’ve flagged this talk, which was filmed at a TEDx event, because it appears to fall outside TEDx’s curatorial guidelines. Given that the intersection of nutrition and mental health is an emerging field of study with limited conclusive evidence, please consult with a mental health professional and do not look to this talk for medical advice.” (

This still impugns Rucklidge’s reputation as a legitimate, credible scientist by claiming it is “outside TEDx’s curatorial guidelines”. That is an outrage; and no less an outrage that TED flags a talk without consulting its author and its sponsor, something that decency as well as plain common sense would dictate.

The only obvious reason for anyone to object to Rucklidge’s talk and work is that she points out that presently used psychiatric drugs do not work for some significant proportion of people who need help; and so mainstream psychiatry and Big Pharma may well feel challenged. But this remains conjecture so long as TED will not explain its actions. Clearly, TED ought to be held accountable; but how?

That question is likely to become more frequent and more pressing as time goes by, because it pertains not only to TED but to an increasing number of ventures on the Internet — Facebook, Twitter, etc., the whole genre nowadays categorized as “social media”.

Perhaps a first necessary step is for the realization to become general and widespread, that “social media” includes TED, TEDx, Wikipedia, and innumerable other sites that offer all sorts of purportedly authoritative, reliable information — dictionary definitions, say — and yet have no evident credentials and are frequently anonymous, offering no contactable individual who could be held accountable for errors or for committing personal libel like that visited on Professor Rucklidge.

In her interview with Moore, Rucklidge mentions the classic case of Semmelweiss as an example of unconventional work that was wrongly disdained by contemporary mainstream experts. Unfortunately, this and the fact of many similar cases are known usually only to historians of science or medicine; for further examples see Dogmatism in Science and Medicine: How Dominant Theories Monopolize Research and Stifle the Search for Truth).

Identifying the Loch Ness Monster

Posted by Henry Bauer on 2018/07/01

Thirty years ago, I explained [1] why science would make no effort to search for the creatures popularly known as Loch Ness Monsters or Nessies: the creatures are seen so rarely that any quest relying on a visual encounter with a Nessie, by eyesight or by photography, would be extremely unlikely to succeed. Scientists cannot sustain a career unless they obtain useful results; at Loch Ness they would be engaged in a war of attrition against the laws of chance, as Adrian Shine once put it. So I have not expected in my lifetime to learn what these creatures really are. Yet now it seems that we will find it out within about a year.

The breakthrough comes from the approach known as “eDNA”, environmental DNA.

“[L]iving things leave behind skin, hair, feathers, poo, bark, pollen and spores as part of their day-to-day activities. These traces result in a potpourri of organic material in our soil and water from which DNA can be extracted and sequenced. Our aim is to produce a census of life in Loch Ness and to establish if there is any scientific basis for the centuries-old monster legend” [2].

It seems incredible, or perhaps magical, but the technique seems to have extraordinary capabilities: “From about a litre or two of water here in Dunedin, we can detect very easily over 150 different species that are present in the inner harbour or the outer harbour” [3].

At Loch Ness, Gemmell’s team “collected 259 water samples from various parts of the loch, including its chilly depths, more than 200 metres down” [2]; so there are good grounds for Nessie believers like myself to be very hopeful that by early in 2019 we will at last know what sort of creature Nessie is.

A common opinion favors something related to the plesiosaurs which supposedly died out roughly 60 million years ago, so presumably authentic plesiosaur DNA is not available for comparison; but snakes and turtles are close relatives in the tree of life with presumably some significant similarities in DNA.

My own best guess, in fact my prediction for what will be found, is that DNA will suggest that Nessies are related to plesiosaurs much as are leatherback turtles, which have been seen at times in the cold waters around Scotland.

Unfortunately, eDNA is not foolproof: “It may be that there is no monster, but we can’t prove that … unfortunately it’s very difficult to prove a negative: the absence of evidence is not evidence of absence. So it might be that if there was a monster, we just didn’t sample water anywhere near where it had been over the last week or so or there may be other explanations” [4].

So we believers have a ready excuse if no marine reptilian DNA turns up. It’s actually a bit worrying if eDNA requires that the organic stuff had been shed within a week or so and somewhere near where the water was sampled — it’s generally agreed that there cannot be more than a couple of dozen Nessies at any given time, and the Loch is about 20 miles long and a mile wide and as deep as nearly 800 feet in some places. That’s why encounters are so rare. Sonar data also suggest that Nessies spend much time at the bottom; and some speculation about physiology and lifestyle suggests significant periods of inactivity.

Still, my hope is that it will be the contemporary doubters, the Nessie denialists, who will need to grasp at straws to find ways to explain away the presence of DNA from some sort of marine reptile. Turtles around the streams that flow into the Loch will be suggested, and much more as well — self-styled skeptics who can maintain that the large, rapidly-moving hump filmed by Tim Dinsdale was actually a boat can surely come up with other absurdly far-fetched suggestions.
We vindicated believers, on the other hand, will move on to point to larger lessons to be drawn from the many decades during which official science managed to ignore or dismiss the staggering amount of evidence: the Dinsdale film, the Rines underwater photos, the innumerable sonar contacts, and the thousands of eyewitness reports.
For a summary of all that evidence and links and references to further detail, see my Loch Ness web-page “Genuine facts about ‘Nessie’, the Loch Ness ‘Monster’”.

Who guards the guardians? Who guards science?

Posted by Henry Bauer on 2018/06/24

Quis custodiet ipsos custodes? This quotation attributed to Juvenal describes the inescapable dilemma as to how societies can be governed .

Today’s guardian of reliable knowledge is science. It is the acknowledged authority on the natural world, on what exists in the world and on how those things behave. Most governments accept as reliable, as true for all practical purposes, whatever the current scientific consensus is: on matters of health, the environment, the solar system, the universe. The mass media, too, accept that scientific consensus; and that largely determines what the general public believes, “what everyone knows”.

Nowadays in that category of “what everyone knows” there are literally innumerable things; among them that the universe began with a Big Bang; that ghosts and Loch Ness Monsters do not exist; that HIV causes AIDS; that hypertension causes heart attacks and strokes; that carbon dioxide released by burning fossil fuels is causing climate change and bringing more frequent and more extreme and more damaging events like hurricanes; etc., etc.

But what guards against the scientific consensus being wrong?

Nothing and nobody.

That really matters, because the history of science is crystal clear that contemporary science, the contemporary scientific consensus, has almost invariably been wrong until further progress superseded and replaced it.

That steady improvement over the centuries gave rise to a comforting shibboleth, that “science is self-correcting”. At any given moment, however, the scientific consensus stands possibly uncorrected and awaiting future “self”-correction. One cannot justifiably assert, therefore, that any contemporary scientific consensus is known to be unquestionably true. It is not known with absolute certainty that the universe began with a Big Bang; that ghosts and Loch Ness Monsters do not exist; that HIV causes AIDS; that hypertension causes heart attacks and strokes; that carbon dioxide released by burning fossil fuels is causing climate change and bringing more frequent and more extreme and more damaging events like hurricanes; etc., etc.

Nevertheless, contemporary society treats these and other contemporary scientific consensuses as true. This amounts to what President Eisenhower warned against: that “public policy could itself become the captive of a scientific-technological elite” [1]. Science can indeed mislead public policy, as when tens of thousands of Americans were forcibly sterilized in the misguided belief that this improved the genetic stock [2]. Science is far from automatically or immediately self-correcting [3].

I’ve wondered how Eisenhower could have been so prescient in 1960, because the conditions that conduce to public policies being misled by science were then just beginning to become prominent: the massive governmental stimulation of scientific activity that has produced today’s dysfunctional hyper-competitiveness, with far too many would-be researchers competing for far too few reliably permanent positions and far too little support for the resources that modern research needs [4]. Moreover, the scientific consensus is guarded not only by the scientists who generated it, powerful societal institutions are vested in the correctness of the scientific consensus [4]: It is virtually inconceivable, for instance, that official bodies like the National Institutes of Health, the Food and Drug Administration, the Centers for Disease Control & Prevention, the World Health Organization, and the like would admit to error of the views that they have promulgated; try to imagine, for example, how it could ever be officially admitted that HIV does not cause AIDS [5].

Reflect on how you formed an opinion about — Big-Bang theory? Loch Ness Monsters? Ghosts? Climate change? … etc. etc. Almost always it will not have been by looking into the evidence but rather by trusting someone’s assertion.

Who has the interest, time, and energy to study all those things? Obviously we must take our beliefs on many matters from trusted authorities; and for a couple of centuries the scientific consensus has been a better guide than most others. But that is no longer the case. The circumstances of 21st-century science mean that society needs guardians to check that what the scientific consensus recommends for public policy corresponds to the best available evidence. On many issues, a minority of experts differs from the scientific consensus, and it would be valuable to have something like a Science Court to assess the arguments and evidence pro and con [6].

I’ve had the luxury of being able to look into quite a few topics because that was appropriate to the second phase of my academic career, in Science & Technology Studies (STS). Through having made a specialty of studying unorthodoxy in science, I stumbled on copious examples of the scientific consensus treating, in recent times, competent minority opinions well within the scientific community with the same disdain, or even worse, as that traditionally directed towards would-be science, fringe science — Loch Ness Monsters, ghosts, UFOS, and the like.

In Dogmatism in Science and Medicine [7], I pointed to the evidence that the contemporary scientific consensus is wrong about Big-Bang theory, global warming and climate change, HIV/AIDS, extinction of the dinosaurs, and more, including what modern medicine says about prescription drugs. The failings of the scientific consensus in modern medicine have been detailed recently by Richard Harris [8] as well as in many works of the last several decades [9]. That the scientific consensus is wrong about HIV and AIDS is documented more fully in The Origin, Persistence and Failings of HIV/AIDS Theory (McFarland, 2007). Why science has become less believable is discussed in [4], which also describes many misconceptions about science and about statistics, the latter bearing a large part of the blame for what’s wrong with today’s medical practices.

But my favorite obsession over where the scientific consensus is wrong remains the existence of Loch Ness “Monsters”, Nessies. It was my continuing curiosity about this that led to my career change from chemistry to STS, which brought many unforeseeable and beneficial side-effects. My 1986 book, The Enigma of Loch Ness: Making Sense of a Mystery [10], showed how the then-available evidence could be interpreted to support belief in the reality of Nessies but could also be plausibly enlisted to reject the reality of Nessies. However, the book’s chief purpose was to explain why seeking to “discover” Nessies was not a sensible task for organized science.

Now in 2018 quite proper science, in the guise of “environmental DNA”, has offered a good chance that my belief in the reality of Loch Ness “Monsters” may be vindicated within a year or so by mainstream science. I plan to say more about that soon.

Science is NOT self-correcting (How science has changed — VII)

Posted by Henry Bauer on 2018/05/06

One of the common and popular shibboleths about science is that it is self-correcting. That implies happening inevitably and automatically. But despite the existence of innumerable scientific organizations and institutions, there is no overarching system or set of protocols or hierarchy that governs all scientific activity. Nothing about scientific activity is automatic or inevitable.

The illusion of self-correction may trace back to the fact that science has surely progressed over time, to better and deeper understanding of how the world works, superseding and rejecting mistakes and misunderstandings. However, this correcting of earlier mis-steps was never automatic; more important, it was never a sure thing. Barber [1] surveyed the long history of hegemonic scientific consensuses vigorously resisting correction. Stent [2] described the phenomenon of “premature discovery” whereby some hegemonic scientific consensuses have forestalled correction for decades — about 40 years with Mendel’s quantitative insight into heredity, about half a century with Wegener’s insight into continental movements.

Barber and Stent dealt with the more-or-less classic modern science that subsisted up until about the middle of the 20th century, the sort of science whose ethos could be fairly adequately described by the Mertonian Norms [3]; a cottage industry of independent, voluntarily cooperating, largely disinterested ivory-tower intellectual entrepreneurs in which science was free to do its own thing, seeking truths about the natural world. Individuals were free to publish their results with little or no hindrance. There were plenty of journals and plenty of journal space, and editors were keen to receive contributions: “From the mid-1800s, there was more journal space than there were articles . . . . assistant editors [had the] . . . primary responsibility . . . to elicit articles and reviews to fill the pages of the publication” [4].

The onus for ensuring that published work was sound rested on the authors, there was not the contemporary gauntlet of “peer reviewers” to run: “for most of the history of scientific journals, it has been editors — not referees — who have been the key decision-makers and gatekeepers. . . . It was only in the late 20th century that refereeing was rebranded as ‘peer review’ and acquired (or reacquired) its modern connotation of proof beyond reasonable doubt. . . . A Google ngram — which charts yearly frequencies of any phrase in printed documents — makes the point starkly visible: it was in the 1970s that the term ‘peer review’ became widely used in English. [We] . . . do not yet know enough about why the post-war expansion of scientific research . . . led to . . . ‘peer review’ [coming] . . . to dominate the evaluation of scholarly research” [5].

Nowadays, by contrast, where publication makes a career and lack of publication means career failure, journals are swamped with submissions at the same time as costs have exploded and libraries are hard pressed to satisfy their customers’ wishes for everything that gets published. Journals are now ranked in prestige by how small a proportion of submissions they accept, and “peer review” is pervaded by conflicts of interest. The overall consequence is that the “leading journals” hew to the current “scientific consensus” so that unorthodoxies, radical novelties, minority views find it difficult to get published. How extreme can be the efforts of “the consensus” to suppress dissent has been profusely documented on a number of topics, including the very publicly visible issues of HIV/AIDS and climate change [6, 7, 8].

Where the consensus happens to be in need of “self-correction”, in other words, today’s circumstances within the scientific community work against any automatic or easy or quick correction.

That situation is greatly exacerbated by the fact that correction nowadays is no simple revising of views within the scientific community. “Science” has become so entwined with matters of great public concern that particular beliefs about certain scientific issues have large groups of influential supporters outside the scientific community who seek actively to suppress dissent from “the consensus”; over HIV/AIDS, those groupies who abet the consensus include the pharmaceutical industry and activist organizations largely supported by drug companies; over climate change, environmentalists have seized on “carbon emissions” as a weapon in their fight for sustainability and stewardship of nature.

Science is not inevitably or automatically self-correcting. Its official agencies, such as the Food and Drug Administration, the Centers for Disease Control & Prevention, the National Institutes of Health, the World Health Organization, etc., are captives of the contemporary scientific consensus and thereby incapable of drawing on the insights offered by minority experts, which is also the case with the peer-review system and the professional journals.

Even when outright fraud or demonstrated honest mistakes have been published, there is no way to ensure that the whole scientific community becomes aware of subsequent corrections or retractions, so errors may continue to be cited as though they were reliable scientific knowledge. Even the journals regarded as the most reliable (e.g. Nature journals, Cell, Proceedings of the National Academy) make it quite difficult for retractions or corrections to be published [9], and even complete retraction seemed to reduce later citation by only about one-third, very far from “self-correcting” the whole corpus of science [10].

How science has changed — VI. The influences of groups

Posted by Henry Bauer on 2018/04/26

Popular stereotypes of scientists picture them as strikingly individual, whether admirably so (Galileo, Darwin, Einstein) or the opposite (Dr. Frankenstein and other mad or evil scientists [1]). That is one of the most significant ways in which the folklore about science differs from today’s reality: Science nowadays is by and large a group activity, and that has many far-reaching corollaries. This is not to deny that scientists see themselves as individuals and act as individuals, but they are also influenced to varying degrees by group memberships and associated loyalties, and that can interfere with truth-seeking.

Memberships in groups and the associated loyalties is a common human experience. First comes the family group; then there is the extended family or clan, and perhaps subgroups of the clan. Other groups cut across different lines, defined by religion, by ethnicity, by nationality; and also, very much pertinent to the circumstances of science, there are groups associated with the way in which we earn a living; we are influenced by our memberships in professional guilds or trade unions.

Under some circumstances it becomes necessary to set priorities with respect to loyalty to the various groups to which we belong. In most circumstances the highest priority is on loyalty to the family, though some individuals have placed a higher priority on religion or some other ideology. Among professional researchers, the most important thing is the current research project and the associated paradigm and scientific consensus: going with this group is the way to further a career whereas dissenting from the group can spell the blighting of a career.

The groups to which scientists belong is one of the most significant aspects of scientific activity, and that has changed fundamentally in recent times, since about WWII.
In the earlier stages of modern science, what we by hindsight describe as scientists were individuals who, for a variety of reasons, were interested in learning to understand the way the natural world works. One of the most crucial foundations of modern science came when groups of such inquiring minds got together, at first informally but soon formally; the Royal Society of London is generally cited as iconic. Those people came together explicitly and solely to share and discuss their findings and their interpretations. At that stage, scientists belonged effectively to just one science-related group, concerned with seeking true understanding of the workings of the world. Since this was a voluntary activity engaged in by amateurs, in other words by people who were not deriving a living or profit from this activity, these early pre-scientists were not much hindered from practicing loyalty simply to truth-seeking; it did not conflict with or interfere with their loyalties to their families or to their religion or to their other social groups.

As the numbers of proto-scientists grew, their associations were influenced by geography and therefore by nationality, so there came occasions when loyalty to truth-seeking was interfered with by questions of who should get credit for particular advances and discoveries. Even in retrospect, British and French sources may differ over whether the calculations for the discovery of Neptune should be credited most to the English John Couch Adams or the French Urbain Le Verrier — and German sources might assert that the first physical observation of the planet was made by Johann Gottfried Galle; again, British and German sources may still differ by hindsight over whether Isaac Newton or Gottfried Wilhelm Leibniz invented the calculus.

Still, for the first two or three centuries of modern science, the explicit ideal or ethos of science was the unfettered pursuit of genuine truth about how the world works. Then, in the 1930s in Nazi Germany and decades later in the Soviet Union, authoritarian regimes insisted that science had to bend to ideology. In Nazi Germany, scientists had to abstain from relativity and other so-called “Jewish” science; in the Soviet Union, chemists had to abstain from the rest of the world’s theories about chemical combination, and biologists had to abstain from what biologists everywhere else knew about evolution. In democratic societies, a few individual scientists were disloyal to their own nations in sharing secrets with scientists in unfriendly other nations, sometimes giving as reason or excuse their overarching loyalty to science, which should not be subject to national boundaries.

By and large, then, up to about the time of WWII, scientific activity was not unlike how Merton had described it [2], which remains the view of it that most people seem still to have of it today: Scientists as truth-seeking individuals, smarter and more knowledgeable than ordinary people, dedicated to science and unaffected by crass self-interest or by conflicts of interest.

That view does not describe today’s reality, as pointed out in earlier posts in this series [2, 3].   The present essay discusses the consequences of the fact that scientists are anything but isolated individuals freely pursuing truth; rather, they are ordinary human beings subject to the pressures of belonging to a variety of groups. Under those conditions, the search for truth can be hindered and distorted.

Chemists (say) admittedly do work individually toward a particular goal, but that goal is not freely self-selected: either it is set by an employer or by a source of funding that considered the proposed work and decided to support it. Quite often, chemists nowadays work in teams, with different individuals focusing on minor specific aspects of some overall project. They are aware of and accommodate in various ways other chemists who happen to be working toward the same or similar goals, be it in the same institution or elsewhere; and they also share some group interests with other chemists in their own institution who may be working on other projects. Chemists everywhere share group interests through national and international organizations and publications. Beyond that, chemists share with biologists, biochemists, physicists and others the group interest of being scientists, having a professional as well as personal interest in the overall prestige and status of science as a whole in the wider society — at the same time as chemists regard their discipline as just a bit “better” than the other sciences, it is “the central science” because it builds on physics and biologists need it; whereas physicists have long known that their discipline is the most fundamental, “the queen of the sciences”, without which there could not be a chemistry or any other science; and so on — biologists know that their field matters much more to human societies than the physical sciences since it is the basis of understanding living things and is indispensable for effective medicine.

So scientists differ among themselves in a number of ways. All feel loyalty to science by comparison to other human endeavors, but especial loyalty to their own discipline; and within that to their particular specialty — among chemists, to analytical or inorganic or organic or physical chemistry; and within each of those to experimental approaches or to theoretical ones. Ultimately, all researchers are obsessed with and loyal to the very specific work they are engaged in every day, and that may be intensely specialized.

For example, researchers working to perfect computer models to mimic global temperatures and climate do just that; they do not have time to work themselves at estimating past temperatures by, for instance, doing isotope analyses of sea-shells. Since such ultra-specialization is necessary, researchers need to rely on and trust those who are working in related areas. So those who are computer-modeling climate take on trust what they are told by geologists about historical temperature and climate changes, and what the meteorologists can tell them about relatively recent weather and climate, and what physicists tell them about heat exchange and the absorption of heat by different materials, and so on.

With all that, despite the fact that research is done within highly organized and even bureaucratic environments, there is actually no overarching authority to monitor and assess what is happening in science, let alone to ensure that things are being done appropriately. In particular, there is no mechanism for deciding that any given research project may have gone off the rails in the sense of drawing unwarranted conclusions or ignoring significant evidence. There is no mechanism to ensure that proper consideration is being given to the views of all competent and informed scientists working on a particular topic.

A consequence is that on quite a range of matters, the so-called scientific consensus, the view accepted as valid by society’s conventional wisdom and by the policy makers, may be at actual odds with inescapable evidence. That circumstance has been documented for example as to the Big-Bang theory in cosmology, the mechanism of smell, the cause of Alzheimer’s disease, the cause of the extinction of the dinosaurs, and more [4].

Of course, the scientific consensus was very often wrong on particular matters throughout the era of modern science. Moreover, the scientific consensus defends itself quite vigorously against the mavericks who point out its errors [5], until eventually the contrary evidence becomes so overwhelming that the old views simply have to give away, in what Thomas Kuhn [6] described as a scientific revolution.

Defense of the consensus illustrates how strong the group influence is on the leading voices in the scientific community; indeed, it has been described as Groupthink [7]. The success of careers, the gaining of eminence and leadership roles hinge on being right, in other words being in line with the contemporary consensus; thus admitting to error can be tantamount to loss of prestige and status and destruction of a career. That is why Max Planck, in the early years of the 20th century, observed that “A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it” [8]; a paraphrase popular among those of us who question an established view is that “Science progresses funeral by funeral”.

At the same time as the history of science teaches that any contemporary scientific consensus is quite fallible and may well be wrong, it also records that — up to quite recent times — science has been able to correct itself, albeit it could take quite a long time — several decades in the case of Mendel’s laws of heredity, or Wegener’s continental drift, or about the cause of mad-cow diseases or of gastritis and stomach ulcers.
Unfortunately it seems as though science’s self-correction does not always come in time to forestall society’s policy-makers from making decisions that spell tangible harm to individuals and to societies as a whole, illustrating what President Eisenhower warned against, that “public policy could itself become the captive of a scientific-technological elite” [9].

More about that in future blog posts.

How science has changed — II. Standards of Truth and of Behavior

Posted by Henry Bauer on 2018/04/08

The scientific knowledge inherited from ancient Babylon and Greece and from medieval Islam was gained by individuals or by groups isolated from one another in time as well as geography. Perhaps the most consequential feature of the “modern” science that we date from the 17th-century Scientific Revolution is the global interaction of the people who are doing science, and especially the continuity over time of their collective endeavors.
These interactions among scientists began in quite informal and individual ways. An important step was the formation of academies and societies, among which the Royal Society of London is usually acknowledged to be the earliest (founded 1660) that has remained active up to the present time — though it was not the earliest such institution and even the claim of “longest continually active” has been challenged [1].
Even nowadays, the global community of scientists remains in many ways informal despite the host of scientific organizations and institutions, national and international: the global scientific community is not governed by any formal structure that lays down how science should be done and how scientists should behave.
However, observing the actualities of scientific activity indicates that there had evolved some agreed-on standards generally seen within the community of scientists as proper behavior. Around the time of the Second World War, sociologist Robert Merton described those informal standards, and they came to be known as the “Mertonian Norms” of science [2]. They comprise:

Ø    Communality or communalism (Merton had said “communism”): Science is an activity of the whole scientific community and it is a public good — findings are shared freely and openly.
Ø    Universalism: Knowledge about the natural world is universally valid and applicable. There are no separations or distinctions by nationality or religion race or anything of that sort.
Ø    Disinterestedness: Science is done for the public good and not for personal benefit; scientists seek to be impartial, objective, unbiased, and not self-serving.
Ø    Skepticism: Claims and reported findings are subject to critical appraisal and testing throughout the scientific community before they can be accepted as proper scientific knowledge.

Note that honesty is not mentioned; it was simply taken for granted.
These norms clearly make sense for a cottage industry, as ideal behavior that individuals should aim for; but they are not appropriate for a corporate environment, they cannot guide the behavior of individuals who are part of some hierarchical enterprise.
In the late 1990s, John Ziman [3] discussed the change in scientific activity as it had morphed from the activities of an informal, voluntary collection of individuals seeking to understand how the world works to a highly organized activity with assigned levels of responsibility and authority and where sources of research funding have a say in what gets done, and which often expect to get something useful in return for their investments, something profitable.
The early cottage industry of science had been essentially self-supporting. Much could be done without expensive equipment. People studied what was conveniently at hand, so there was little need for funds to support travel. Interested patrons and local benefactors could provide the small resources needed for occasional meetings and the publication of findings.
Up to about the middle of the 20th century, universities were able to provide the funds needed for basic research in chemistry and biology and physics. The first sign that exceptional resources could be needed had come in the 1920s when Lawrence constructed the first large “atom-smashing machine”; but that and the need for expensive astronomical telescopes remained outliers in the requirements for the support of scientific research overall.
From about the time of the Second World War, however, research going beyond what had already been accomplished began to require ever more expensive and specialized equipment as well as considerable infrastructure: technicians to support the equipment, glass-blowers and secretaries and book-keepers and librarians, and managers of such ancillary staff; so researchers increasingly came to need support beyond that available from individual patrons or universities. Academic research came to rely increasingly on getting grants for specific research projects from public agencies or from wealthy private foundations.
Although those sources of research funds typically claim that they want to support simply “the best science”, their view of what the best science is does not necessarily jibe with the judgments of the individual researchers [4].
At the same time as research in universities was calling on outside sources of funding, an increasing number of industries were setting up their own laboratories for research specifically toward creating and improving their products and services. Such product-specific “R&D” (research and development) sometimes turned up novel basic knowledge, or revealed the need for such fundamentally new understanding. One consequence has been that some really striking scientific advances have come from such famous industrial laboratories as Bell Telephone Laboratories or the Research Laboratory of General Electric. Researchers employed in industry have received a considerable number of Nobel Prizes, often jointly with academics [5].
Under these new circumstances, as Ziman [3] pointed out, the traditional distinction between “applied” research and “pure” or “basic” research lost its meaning.
Ziman rephrased the Mertonian norms as the nice acronym CUDOS, adding the “O” for originality, quite appropriately since within the scientific community credit was and is given to for the most innovative, original contributions; CUDOS, or preferably “kudos”, being the Greek term for acclaim of exceptional accomplishment. By contrast, Ziman proposed for the norms that obtain in a corporate scientific enterprise, be it government or private, the acronym PLACE: Researchers nowadays get their rewards not by adhering to the Mertonian norms but by producing Proprietary findings whose significance may be purely Local rather than universal, the subject of research having been chosen under the Authority of an employer or patron and not by the individual researcher, who is Commissioned to do the work as an Expert employee.

Ziman too did not mention honesty; like Merton he simply took it for granted.
Ziman had made an outstanding career in solid-state physics before, in his middle years, he began to publish, starting in 1968 [6] highly insightful works about how science functions, in particular what makes it reliable. In the late 1960s, it had still been reasonable to take honesty in science for granted; but by the time Ziman published Prometheus Bound, honesty in science could no longer be taken for granted; Ziman had failed to notice some of what was happening in scientific activity. Competition for resources and for career advancement had increased to a quite disturbing extent, presumably the impetus for the increasing frequency with which scientists were found to have cheated in some way. Even published, supposedly peer-reviewed research failed later attempted confirmation in many cases, and all too often it was revealed as simply false, faked [7].

Dangerous knowledge IV: The vicious cycle of wrong knowledge

Posted by Henry Bauer on 2018/02/03

Peter Duesberg, universally admired scientist, cancer researcher, and leading virologist, member of the National Academy of Sciences, recipient of a seven-year Outstanding Investigator Grant from the National Institutes of Health, was astounded when the world turned against him because he pointed to the clear fact that HIV had never been proven to cause AIDS and to the strong evidence that, indeed, no retrovirus could behave in the postulated manner.

Frederick Seitz, at one time President of the National Academy of Sciences and for some time President of Rockefeller University, became similarly non grata for pointing out that parts of an official report contradicted one another about whether human activities had been proven to be the prime cause of global warming (“A major deception on global warming”, Wall Street Journal, 12 June 1996).

A group of eminent astronomers and astrophysicists (among them Halton Arp, Hermann Bondi, Amitabha Ghosh, Thomas Gold, Jayant Narlikar) had their letter pointing to flaws in Big-Bang theory rejected by Nature.

These distinguished scientists illustrate (among many other instances involving less prominent scientists) that the scientific establishment routinely refuses to acknowledge evidence that contradicts contemporary theory, even evidence proffered by previously lauded fellow members of the elite establishment.

Society’s dangerous wrong knowledge about science includes the mistaken belief that science hews earnestly to evidence and that peer review — the behavior of scientists — includes considering new evidence as it comes in.

Not so. Refusal to consider disconfirming facts has been documented on a host of topics less prominent than AIDS or global warming: prescription drugs, Alzheimer’s disease, extinction of the dinosaurs, mechanism of smell, human settlement of the Americas, the provenance of Earth’s oil deposits, the nature of ball lightning, the evidence for cold nuclear fusion, the dangers from second-hand tobacco smoke, continental-drift theory, risks from adjuvants and preservatives in vaccines, and many more topics; see for instance Dogmatism in Science and Medicine: How Dominant Theories Monopolize Research and Stifle the Search for Truth, Jefferson (NC): McFarland 2012. And of course society’s officialdom, the conventional wisdom, the mass media, all take their cue from the scientific establishment.

The virtually universal dismissal of contradictory evidence stems from the nature of contemporary science and its role in society as the supreme arbiter of knowledge, and from the fact of widespread ignorance about the history of science, as discussed in earlier posts in this series (Dangerous knowledge; Dangerous knowledge II: Wrong knowledge about the history of science; Dangerous knowledge III: Wrong knowledge about science).

The upshot is a vicious cycle. Ignorance of history makes it seem incredible that “science” would ignore evidence, so claims to that effect on any given topic are brushed aside — because it is not known that science has ignored contrary evidence routinely. But that fact can only be recognized after noting the accumulation of individual topics on which this has happened, evidence being ignored. That’s the vicious cycle.

Wrong knowledge about science and the history of science impedes recognizing that evidence is being ignored in any given actual case. Thereby radical progress is nowadays being greatly hindered, and public policies are being misled by flawed interpretations enshrined by the scientific consensus. Society has succumbed to what President Eisenhower warned against (Farewell speech, 17 January 1961) :

in holding scientific research and discovery in respect, as we should,
we must also be alert to the equal and opposite danger
that public policy could itself become the captive
of a scientific-technological elite.

The vigorous defending of established theories and the refusal to consider contradictory evidence means that once theories have been widely enough accepted, they soon become knowledge monopolies, and support for research establishes the contemporary theory as a research cartel(“Science in the 21st Century: Knowledge Monopolies and Research Cartels”).

The presently dysfunctional circumstances have been recognized only by two quite small groups of people:

  1. Observers and critics (historians, philosophers, sociologists of science, scholars of Science & Technology Studies)
  2. Researchers whose own experiences and interests happened to cause them to come across facts that disprove generally accepted ideas — for example Duesberg, Seitz, the astronomers cited above, etc. But these researchers only recognize the unwarranted dismissal of evidence in their own specialty, not that it is a general phenomenon (see my talk, “HIV/AIDS blunder is far from unique in the annals of science and medicine” at the 2009 Oakland Conference of Rethinking AIDS; mov file can be downloaded at, but streaming from there does not work).

Such dissenting researchers find themselves progressively excluded from mainstream discourse, and that exclusion makes it increasingly unlikely that their arguments and documentation will gain attention. Moreover, frustrated by a lack of attention from mainstream entities, dissenters from a scientific consensus find themselves listened to and appreciated increasingly only by people outside the mainstream scientific community to whom the conventional wisdom also pays no attention, for instance the parapsychologists, ufologists, cryptozoologists. Such associations, and the conventional wisdom’s consequent assigning of guilt by association, then entrenches further the vicious cycle of dangerous knowledge that rests on the acceptance of contemporary scientific consensuses as not to be questioned — see chapter 2 in Dogmatism in Science and Medicine: How Dominant Theories Monopolize Research and Stifle the Search for Truth and “Good Company and Bad Company”, pp. 118-9 in Science Is Not What You Think: How It Has Changed, Why We Can’t Trust It, How It Can Be Fixed (McFarland 2017).
