21st century science:   Group-Thinking Elites and Fanatical Groupies

Posted by Henry Bauer on 2018/08/11

Science has been a reliable resource for official policies and actions for much of the era of modern science, which is usually regarded as having begun around the 17th century.

It is almost without precedent that a mistaken scientific consensus should lead to undesirable and damaging public actions, yet that is now the case in two instances: the belief that carbon dioxide generated by the burning of fossil fuels is primarily responsible for global warming and climate change; and the belief that HIV is the cause of AIDS.

Both those beliefs gained hegemony during the last two or three decades. That these beliefs are mistaken seems incredible to most people, in part because of the lack of any well known precedent and in part because the nature of science is widely misunderstood; in particular it is not yet widely recognized how much science has changed since the middle of the 20th century.

The circumstances of modern science that conspire to make it possible for mistaken theories to bring misguided public policies have been described in my recent book, Science Is Not What You Think [1]. The salient points are these:

Ø     Science has become dysfunctionally large

Ø     It is hyper-competitive

Ø     It is not effectively self-correcting

Ø     It is at the mercy of multiple external interests and influences.

A similar analysis was offered by Judson [2]. That title reflects the book’s opening theme of the prevalence of fraud in modern science (as well as in contemporary culture). It assigns blame to the huge expansion in the number of scientists and the crisis that the world of science faces as it finds itself in something of a steady-state so far as resources are concerned, after a period of some three centuries of largely unfitted expansion: about 80% of all the scientists who have ever lived are extant today; US federal expenditure on R&D increased 4-fold (inflation-adjusted!) from 2003 to 2002, and US industry increased its R&D spending by a factor of 26 over that period! Judson also notes the quintessential work of John Ziman explicating the significance of the change from continual expansion to what Ziman called a dynamic steady-state [3].

Remarkably enough, President Eisenhower had foreseen this possibility and warned against it in his farewell address to the nation: “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 proponents of human-caused-climate-changer theory and of HIV/AIDS theory are examples of such elites.

A crucial factor is that elites, like all other groups, may be dysfunctionally affected by the phenomenon of Groupthink.

Janis [4] showed in detail several decades ago how that phenomenon of Groupthink had produced disastrously bad policy actions by the United States. The same phenomenon of Groupthink can cause bad things to happen in other social sectors than the government. Recently, Booker [5] has shown how Groupthink has been responsible for making it a worldwide belief, a shibboleth, a cliché, that humankind’s use of fossil fuels is causing global warming and climate change through the release of carbon dioxide.

Commonly held ideas about science do not envisage the possibility that a scientific consensus could bring misguided policies and actions on a global scale. What most people know — think they know — about science is that its conclusions are based on solid evidence, and that the scientific method safeguards against getting things wrong, and that science that has been primarily responsible for civilization’s advances over the last few centuries.

Those things that most people know are also largely mistaken [1, 6]. Science is a human activity and is subject to all the frailties and fallibilities of any human activity. The scientific method and the way in which it is popularly described does not accurately portray how science is actually done.

While much of the intellectual progress in understanding how the world works does indeed stand to the credit of science, what remains to be commonly realized is that since about the middle of the 20th century, science has become too big for its own good. The huge expansion of scientific activity since the Second World War has changed science in crucial ways. The number of people engaged in scientific activity has far outstripped the available resources, leading to hyper-competition and associated sloppiness and outright dishonesty. Scientists nowadays are in no way exceptional individuals, people doing scientific work are as common as are teachers, doctors, or engineers. It is in this environment that Groupthink has become significantly and damagingly important.

Booker [5] described this in relation to the hysteria over the use of fossil fuels. A comparable situation concerns the belief that HIV is the cause of AIDS [7]. The overall similarities in these two cases are that a quite small number of researchers arrived initially at more or less tentative conclusions; but those conclusions seemed of such great import to society at large that they were immediately seized upon and broadcast by the media as breaking news. Political actors become involved, accepting those conclusions quickly became politically correct, and those who then questioned and now question the conclusions are vigorously opposed, often maligned as unscientific and motivated by non-scientific agendas.

 

At any rate, contemporary science has become a group activity rather than an activity of independent intellectual entrepreneurs, and it is in this environment that Groupthink affects the elites in any given field — the acknowledged leading researchers whose influence is entrenched by editors and administrators and other bureaucrats inside and outside the scientific community.

A concomitant phenomenon is that of fanatical groupies. Concerning both human-caused climate change and the theory that HIV causes AIDS, there are quite large social groups that have taken up the cause with fanatical vigor and that attack quite unscrupulously anyone who differs from the conventional wisdom. These groupies are chiefly people with little or no scientific background, or whose scientific ambitions are unrequited (which includes students). As with activist groups in general, groupie organizations are often supported by (and indeed often founded by) commercial or political interests. Non-profit organizations which purportedly represent patients and other concerned citizens and which campaign for funds to fight against cancer, multiple sclerosis, etc., are usually funded by Big Pharma, as are HIV/AIDS activist groups.

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.” (https://www.youtube.com/watch?v=3dqXHHCc5lA)

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).

Human-caused global warming as Groupthink

Posted by Henry Bauer on 2018/08/02

Carbon dioxide (CO2) in the atmosphere
is not
the overarching determinant of global temperature.

Over the life of the Earth, carbon dioxide levels have been far higher than now during Ice Ages, for example. Since the mid-19th-century Industrial Revolution, levels of carbon dioxide have increased while temperatures were cooling rather than warming during ~1880-1910 and ~1940-1970s, and they have remained relatively steady since ~1998; see sources cited in Climate-change facts: Temperature is not determined by carbon dioxide. The lack of warming since the start of the 21st century is acknowledged surreptitiously by the Royal Society of London and the U.S. National Academy of Sciences in offering attempted explanations for it.

Since the evidence is quite clear, there exists a great mystery:
How has it happened that essentially the whole official world insists mistakenly that human generation of carbon dioxide is causing unnatural warming and climate change?

How could that happen in this modern era in which science is the supreme intellectual authority?

A huge literature of books, articles, pamphlets, and blogs has rehearsed the substantive flaws in the belief that human generation of carbon dioxide is causing global warming (AGW, Anthropogenic Global Warming) and climate change (ACC). There has not, however, been the same degree of analysis of how national and international institutions have come to accept this mistaken notion to the extent of making policies based on it.

Christopher Booker has now offered an explanation in GLOBAL WARMING: A case study in groupthink.

By “science” Booker here means psychology. He invokes and applies the concept of Groupthink which had been developed by psychologist Irving Janis [1, 2] several decades ago:

“Janis’s focus was on decision-making in the foreign policy arena. However, as soon as you look, you see that his ideas apply elsewhere. The climate debate is a case in point — all of the characteristic ‘rules’ of groupthink are there: warmist ideas can’t be tested against reality, and so to ensure they are upheld as the truth, they have to be elevated into a ‘consensus’ and anyone who challenges them must be crushed. These are precisely the features that Janis used to define Groupthink.”

So just as Groupthink led to the policy disasters of Pearl Harbour, the Bay of Pigs fiasco and Johnson’s escalation of the Vietnam war, attempts to suppress serious debate of climate science and the policies that are being promoted as solutions are leading to irrational behaviour, costly policy blunders and corruption on an unprecedented scale. This will only end when groupthink eventually bumps up against reality.

As Booker puts it in his conclusions:

“Every South Sea Bubble ends in a crash. Every form of Groupthink eventually has its day. This is invariably what happens when human beings get carried along by the crowd, simply because they have lost the urge or ability to think for themselves” [3].

I would differ with that last comment, however. Human beings do not customarily lose the urge or ability to think for themselves, all too often they never acquired it. That ability is not genetically inherent and it has to be gained against strong odds. We humans are raised to believe what we’re taught, by parents, by teachers, and by preachers and sundry self-appointed prophets; nowadays, by intrusive media and innumerable internet sources claiming to offer reliable facts and insights. The question is not, how people can believe clearly wrong things, even absurd things: examples are everywhere of people devoutly believing things that are against logic and against tangible facts. The mystery is how some people manage, at least some of the time, to come to think for themselves by forming beliefs on the basis of evidence, thereby rejecting their earlier indoctrination [4].

Booker describes the essential characteristics of Groupthink as
Ø      A group of people come to share a particular view or belief.
Ø      They insist that their belief is shared by a ‘consensus’ of all right-minded opinion
Ø      They defend it with irrational, dismissive hostility towards anyone who disagrees.

GLOBAL WARMING: A case study in groupthink shows rather convincingly how these factors played out in the rise and subsequent hegemony of AGW belief.

This historical analysis is invaluable in revealing the specific actions of specific actors that led initially to AGW belief among a group of scientists. That belief was congenial to various groups, outside the scientific community (notably environment al activists) whose internal consensuses then in turn also display the characteristic features of Groupthink.

Beliefs come in a very wide range of degrees of intensity. Human groups display conformity in matters small and large, sometimes to the degree of unanimity, and Groupthink is intellectual conformity that demands unanimity within the group.
Over AGW, this demand for unanimity is displayed in actions as well as words, in the conviction of being right and the hostility towards disbelievers, as when the latter are referred to as ignoramuses (“Flat-Earthers” is a common epithet) or as “denialists”, harking to the morally despicable genre of Holocaust deniers.

It has not often enough been remarked, how extraordinary it is that disagreements between scientists reach the level of hostility of charging fellow scientists not just with being ridiculously wrong but also with being as morally despicable as Holocaust deniers. And it also goes against the conventional wisdom about science to suggest that Groupthink exists in the scientific community. Popularly, scientists are regarded as strikingly individual, whether it be in a laudable way (Galileo, Darwin, Einstein) or the opposite (Dr. Frankenstein and other mad or evil scientists [5]). The conventional wisdom has not yet grasped just how drastically different today’s science is from its popular image; that was formed by the earlier centuries of modern (since ~17th century) and has not digested the enormous changes since about World War II [6]. Science nowadays is by and large a group activity. That is not to deny that scientists see themselves as individuals, but they are also to varying degrees subject to group influences. Chemists (say) not only do individual work toward a particular goal, they are aware of and accommodate in various ways the other chemists 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, of having a professional as well as personal interest in the prestige and status of science in the wider society.

The most intense group feeling of course concerns whatever the immediate research project is, since that determines professional career status, prestige, future prospects. If it were to turn out that AGW is wrong, that human generation of carbon dioxide is not causing global warming and climate change, this would be devastating for the careers of current proponents of AGW, and for their institutions. Little wonder, then, that the dogma of AGW is defended with such determination.

Intense competitiveness in science and its sad consequences became significant only since the second or third quarter of the 20th century, so AGW is something of a new phenomenon, international acceptance of a mistaken scientific consensus. There is one other instance already, though, which also took hold in the last couple of decades of the 20th century: the theory that HIV causes AIDS. That is distinctly contrary to copious evidence (The Case against HIV) yet it is propounded and defended so determinedly that it is simply inconceivable that official bodies would ever come to acknowledge that the theory is wrong (OFFICIAL!   HIV does not cause AIDS!).

 

It is a sad fact
that in the era of Fake (Political) News,
there has also come into being
Fake Scientific Consensuses.

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].

SUGGESTION TO THE READER:
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 changed — V. And changed academe

Posted by Henry Bauer on 2018/04/19

After WWII, lavish support for science made it a cash cow that academe used to change itself; a change abetted by the corruption of collegiate sport.

*               *               *              *                 *                *              *               *

Science began as an informal cottage industry; nowadays it is a highly organized bureaucratic behemoth that is pervasively intertwined with other sectors of human society.

Science began as a disinterested quest to understand how the world works; practical applications were an incidental though welcome byproduct. Nowadays, society values science for its byproducts more than for the truths it reveals about Nature.

Teaching institutions, colleges, universities were founded to educate (albeit sometimes indoctrinate) future generations. Nowadays much of academe has become a self-serving enterprise in which institutions seek status and prestige from what used to be incidental byproducts; research in academe now has an immediate eye out for patents and potential commercial applications, and intercollegiate sports for local enjoyment have become means of mass entertainment for lucrative revenue. A research university will have many dozens of administrators engaged in managing grant-related matters, intellectual property matters, compliance with regulations, status of research staff, and so on. Almost every university has many dozens of administrative staff engaged in managing its intercollegiate sports programs as well as coaches (whose salaries often exceed those of the university president) and assistant coaches (whose salaries are comparable to or exceed those of full professors).

*                  *                 *                *                *                *                *                *

Scientific activity changed from a cottage industry quite slowly at first, and in fits and starts. Already in the 19th century science had been important in the commercial dye-stuff industry. During the First World War, the German war effort was supported by the discovery, by the chemist Fritz Haber, how to synthesize fertilizers and explosives using the nitrogen in the air. During the 1930s, medical practice began to have genuinely curative capabilities with the discovery of bacteria-killing sulfonamides. But, by and large, up to the Second World War scientific activity remained something of a cottage industry, and basic scientific research was largely an academic ivory-tower activity.

World War II demonstrated the powerful capabilities of applications of scientific understanding; not only the war-ending atomic bombs but also and earlier the sonar that was such an invaluable weapon against submarines and the radar that was invaluable to Great Britain in staving off the German Blitzkrieg bombers; as well as all sorts of developments and improvements in weaponry in techniques of communication and of navigation.

Vannevar Bush had been director of the U.S. Office of Scientific Research and Development, seeing at first hand what science could accomplish. Shortly after the end of World War II he presented the president of the United States with a report entitled Science: The Endless Frontier,  which suggested that scientific research and development could be as valuable to peacetime society as science had proved to be in warfare.

Bush’s initiative is generally credited for the subsequent enormous, unprecedented resources directed into the expansion of scientific activity. The federal support of science came in part as grants to support research activity in the form of specific proposed projects, but also in large part through scholarships and fellowships to stimulate more students to go into science as a career.

That influx of funds led to truly far-reaching changes in academe.

Traditionally, the role of universities was to provide tertiary education, preparing people for the professions. A small proportion of academe comprised so-called “research universities” where the faculty were as much concerned with extending the boundaries of scholarship and of science as they were with the education and training of students; yet the research and scholarship were designed to serve the aim of educating students to become independent professionals. However, the emphasis on scientific research and on training more scientists led eventually to the contemporary circumstances where the primary aim is determined by the demands of the research project rather than by whether the work is best suited for the students to learn how to do independent research. Graduate students came to be seen as cheap technical help rather than as apprentices to be nurtured; science faculty among themselves could be heard referring to the graduate students they were mentoring as “pairs of hands”. In earlier days, prospective graduate students in the sciences would choose their mentors to fit with the students’ specific research interests; nowadays graduate students in the sciences sign on to mentors who have the research grants to support them and they work as cogs in the mentor’s long-term research program [1].

The overt aim of supporting and enhancing science had the corollary effect, no doubt unforeseen and unintended, of making science more prestigious than other intellectual fields within colleges and universities. In time, that tempted some of those other fields to distort themselves in trying to mimic science and gain comparable status and prestige thereby. And not only intellectual prestige: science (and engineering and medical) faculty had higher salaries than faculty in the humanities and the social sciences, and moreover scientists could augment their academic ”9-month” salaries with an extra 20-30% from their research grants as summer-time stipends.

In the humanities, for example — philosophy, history, to some degree psychology — scholarship traditionally focused on critical analysis of traditional classical insights gained by earlier scholars, with comparatively little expectation that entirely novel, ground-breaking insights could be attained. Scholars in the humanities would occasionally publish critiques and analyses and perhaps eventually scholarly monographs. By contrast, in the sciences the emphasis was on novelty, on going beyond what was already known. As other parts of academe developed the ambition to be as well-supported fiscally and thereby as highly regarded as the sciences, they also came to emphasize originality and publication. Graduate students working towards doctoral degrees in history or psychology or sociology are nowadays supposed to generate stuff that deserves publication, often as a monograph. The sciences have become an inappropriate role model for other intellectual disciplines.

The pots of gold available for science-related activities also tempted whole institutions, four-year colleges and teachers’ colleges in particular, to seek prestige and status by transforming themselves into “research” universities. By hiring scientists, grants could be obtained whose amounts were calculated not only to cover the actual costs of the research but also “overhead” costs to reimburse the whole institution for the use of its infrastructure pertinent to the research (“indirect costs” became a popular euphemism for “overhead”). Those indirect costs could be as high as a 50% surcharge on the actual costs of research, and that provided a pool of money that upper-level administrators could draw on for all sorts of things. In the 1940s, the United States had 107 doctorate-granting research universities; by 1950–54 there were 142, by 1960–64 there were 208, and by 1970–74 the number had grown to 307 [2]; since then the rate of growth has been much less, with a count of 334 in 2016 [3 ].

 

The influx of science-related money may have stimulated academe to change in inappropriate and undesirable ways, but science cannot be held responsible for all of today’s ills of academe. Like science, like sports, like so much else, academe has been corrupted by the love of money. One of the most serious consequences is the progressive elimination of tenure-track faculty, replaced by teachers on fixed-term contracts. Academic freedom cannot exist in the absence of tenure, and genuine freedom of thought, expression, and criticism cannot exist in the absence of academic freedom.

Perhaps the most fundamental problem is that both academe and science both should be venues for unfettered truth-seeking activities. But truth-seeking is inevitably subversive, and it is never supported for its own sake by the powers that be. The corruption and distortion of science and academe make it easier for non-truths to spread, which is dangerous for the long-term health of society.

How science changed — IV. Cutthroat competition and outright fraud

Posted by Henry Bauer on 2018/04/15

The discovery of the structure of DNA was a metaphorical “canary in the coal mine”, warning of the intensely competitive environment that was coming to scientific activity. The episode illustrates in microcosm the seismic shift in the circumstances of scientific activity that started around the middle of the 20th century [1], the replacement of one set of unwritten rules by another set [2].
The structure itself was discovered by Watson and Crick around 1950, but it was only in 1968, with the publication of Watson’s personal recollections, that attention was focused on how Watson’s approach and behavior marked a break from the traditional unwritten rules of scientific activity.
It took even longer for science writers and journalists to realize just how cutthroat the competition had become in scientific and medical research. Starting around 1980 there appeared a spate of books describing fierce fights for priority on a variety of specific topics:
Ø    The role of the brain in the release of hormones; Guillemin vs. Schally — Nicholas Wade, The Nobel Duel: Two Scientists’ 21-year Race to Win the World’s Most Coveted Research Prize, Anchor Press/Doubleday, 1981.

Ø    “‘Mentor chains’, characterized by camaraderie and envy, for example in neuroscience and neuropharmacology” — Robert Kanigel, Apprentice to Genius: The Making of a Scientific Dynasty, Macmillan, 1986.
Ø    High-energy particle physics, atom-smashers — Gary Taubes, Nobel Dreams: Power, Deceit, and the Ultimate Experiment, Random House, 1986.
Ø    “Soul-searching, petty rivalries, ridiculous mistakes, false results as rivals compete to understand oncogenes” — Natalie Angier, Natural Obsessions: The Search for the Oncogene, Houghton Mifflin, 1987.
Ø    “The brutal intellectual darwinism that dominates the high-stakes world of molecular genetics research” — Stephen S. Hall, Invisible Frontiers: The Race to Synthesize a Human Gene, Atlantic Monthly Press, 1987.
Ø    “How the biases and preconceptions of paleoanthropologists shaped their work” — Roger Lewin, Bones of Contention: Controversies in the Search for Human Origins, Simon & Schuster, 1987.
Ø    “The quirks of . . . brilliant . . . geniuses working at the extremes of thought” — Ed Regis, Who Got Einstein’s Office: Eccentricity and Genius at the Institute for Advanced Study, Addison-Wesley, 1987.
Ø    High-energy particle physics — Sheldon Glashow with Ben Bova, Interactions: A Journey Through the Mind of a Particle Physicist and the Matter of the World, Warner, 1988.
Ø    Discovery of endorphins — Jeff Goldberg, Anatomy of a Scientific Discovery, Bantam, 1988.
Ø    “Intense competition . . . to discover superconductors that work at practical temperatures “ — Robert M. Hazen, The Breakthrough: The Race for the Superconductor, Summit, 1988.

These titles illustrate that observers were able to find intense competitiveness wherever they looked in science; though mostly in medical or biological science, with physics including astronomy the next most frequently mentioned field of research.
Watson’s memoir had not only featured competition most prominently, it had also revealed that older notions of ethical behavior no longer applied: Watson was determined to get access to competitors’ results even if those competitors were not yet anxious to reveal all to him [3]. It was not only competitiveness that increased steadily over the years; so too did the willingness to engage in behavior that not so long before had been regarded as improper.
Amid the spate of books about how competitive research had become, there also was published. Betrayers of the Truth: Fraud and Deceit in the Halls of Science by science journalists William Broad and Nicholas Wade (Simon & Schuster, 1982). This book argued that dishonesty has always been present in science, citing in an appendix 33 “known or suspected” cases of scientific fraud from 1981 back to the 2nd century BC. These actual data could not support the book’s sweeping generalizations [4], but Broad and Wade had been very early to draw attention to the fact that dishonesty in science was a significant problem. What they failed to appreciate was why: not that there had always been a notable frequency of fraud in science but that scientific activity was changing in ways that were in process of making it a different kind of thing than in the halcyon few centuries of modern science from the 17th century to the middle of the 20th century.
Research misconduct had featured in Congressional Hearings as early as 1981. Soon the Department of Health and Human Services established an Office of Scientific Integrity, now the Office of Research Integrity. Its mission is to instruct research institutions about preventing fraud and dealing with allegations of it. Scientific periodicals began to ask authors to disclose conflicts of interest, and co-authors to state specifically what portions of the work were their individual responsibility.
Academe has proliferated Centers for Research and Medical Ethics [5], and there are now periodicals entirely devoted to such matters [6]. Courses in research ethics have become increasingly common; it is even required that such courses be available at institutions that receive research funds from federal agencies.
In 1989, the Committee on the Conduct of Science of the National Academy of Sciences issued the booklet On Being a Scientist, which describes proper behavior; that booklet’s 3rd edition, titled A Guide to Responsible Conduct in Research, makes even clearer that the problem of scientific misconduct is now widely seen as serious.
Another indication that dishonesty has increased is the quite frequent retraction of published research reports: Retraction Watch estimates that 500-600 published articles are retracted annually. John Ioannidis has made a specialty of reviewing literature for consistency, and reported: “Why most published research findings are false” [7]. Nature has an archive devoted to this phenomenon [8].

Researchers half a century ago would have been aghast and disbelieving at all this, that science could have become so untrustworthy. It has happened because science changed from an amateur avocation to a career that can bring fame and wealth [9]; and scientific activity changed from a cottage industry to a highly bureaucratic corporate industry, with pervasive institutional as well as individual conflicts of interest; and researchers’ demands for support have far exceeded the available supply.

And as science changed, it drew academe along with it. More about that later.

How science changed — III. DNA: disinterest loses, competition wins

Posted by Henry Bauer on 2018/04/10

The Second World War marked a shift of economic and political power from Europe to the United States, with associated changes in the manner and style with which those powers are deployed. Science began to change at about the same time and in somewhat analogous and perhaps associated ways.

The change in the norms of science, from CUDOS to PLACE, that Ziman had described (How science has changed — II. Standards of Truth and of Behavior) began with what happened in the middle of the 20th century. The first of the Mertonian norms to fade away was disinterestedness: Science came to be like other spheres of human activity in that some people chose to pursue it as an avenue for satisfying personal ambition rather than as an opportunity to serve the public good.

My cohort of science students in Australia in the early 1950s had been notably idealistic about science. We could imagine no finer future then the opportunity to earn a living doing science. The relative absence of excessive personal ambition may have stemmed in large part from the fact that Australia was at that time a profoundly egalitarian society; no one should imagine himself to be “better” than anyone else [1].

Our ideals about science included taking honesty for granted, as Merton had.

Our ranking of desirable occupations had doing research in a university setting at the top. Those who were not good enough to do innovative self-directed research would still be able to have a place in science by working in industry. If one were not talented enough even for that, one would have to make do with teaching science. And if one could not even do that, then it would have to be some sort of administrative job. I still recall the minor functionary at the University of Sydney who represented a living lesson for us in the wages of sin: As a graduate student in chemistry, he had faked some of his results, and so he had been condemned to lifelong labor as a paper pusher.

The sea change in science around the middle of the 20th century is illustrated in microcosm by the circumstances of the discovery of the structure of DNA by James Watson and Francis Crick. Watson’s description of that discovery in his memoir, The Double Helix (Atheneum, 1968), and the reactions to that book in the scientific community, illustrate the profound changes in scientific activity beginning to take place around that time. Gunther Stent’s annotated edition of The Double Helix [2] provides a ready source for appreciating how the DNA discovery touches on many aspects of how scientific activity changed profoundly, beginning in the middle of the 20th century; the edition includes the original text of the book, commentaries, many of the original book reviews, and pertinent articles.

Watson himself, as portrayed in his own memoir, exemplifies the brash, personally ambitious American ignorant of or simply ignoring the traditional ways of doing things, in personal behavior as well as in doing science [3].

In Watson’s memoir, traditional ways including disinterestedness are exemplified by the Europeans Max Perutz and Erwin Chargaff. Perutz had been working diligently for a decade or so, gradually refining what could be learned about the structure of proteins through the technique of X-ray crystallography. With similar diligence Erwin Chargaff had been analyzing the chemical constitutions of DNA from a variety of different sources. Both those research approaches comported with traditional experience that carefully accumulating sufficient pertinent information would eventually be rewarded by important new understanding. In Britain, since Maurice Wilkins and Rosalind Franklin were working on DNA structure via X-ray crystallography, no other British lab would trespass onto that research project.

Watson of course had no such scruples, nor was he prepared to wait for the traditional ways to pay off; Watson’s own words make it appear that his prime motivation was to make a name for himself — any advance in human understanding, for the public good, would be a byproduct.

To short-circuit old-fashioned laborious approaches, he and his co-worker Francis Crick looked to what had been pioneered by another American, Linus Pauling, who is often still regarded as the outstanding chemist of the 20th century. Pauling did also use X-ray crystallography, but only as a secondary adjunct. He had laid the foundations for an understanding of chemical bonding and had been interested from the beginning in the three-dimensional structures of molecules; applying his insights to the study of macromolecules, he succeeded in elucidating the configuration of protein molecules in part by constructing feasible molecular models.

Traditional cosmopolitan European culture could be disdainful and snobbish toward the parvenu, nouveau-riche American ways that were taking over the world, including the world of science. Erwin Chargaff provides an apposite, rather sad illustration. He disliked not only Watson’s personality and actions, he led himself to believe that his own diligent traditional work on the chemical composition of DNA should have been rewarded by a share of the Nobel Prize. Chargaff’s review [4] of The Double Helix flaunts his cultured erudition and also reveals his personal disappointment; later he refused Gunther Stent permission to reprint his review, in company with all the others, in Stent’s annotated edition.

The technical point at issue is that Chargaff had been content to allow results to accumulate until insight revealed itself rather than to take a gamble on some premature interpretation: he had merely remarked on an apparently consistent ratio of purines to pyrimidines in the DNA from a variety of sources [5]: “It is . . . noteworthy — whether this is more than accidental cannot yet be said — that in all deoxypentose nucleic acids examined thus far the molar ratios of total purines to total pyrimidines, and also of adenine to thymine and of guanine to cytosine, were not far from 1”.

The important insight, however, is that the numbers are exactly equal; adenine faces thymine, and guanine faces cytosine in the molecular structure of DNA, and that is the central and crucial feature of the double helix. In hindsight, Chargaff wanted his tentative statement of approximate equality to be construed as “the discovery of   the base-pairing regularities” [4].

Erwin Chargaff may have been acerbic and ungenerous in his book review, but he will also have spoken for generations of scientists in his regret for the passing of the more idealistic, disinterested, traditional order and distaste for what was replacing it: “in our time a successful cancer researcher is not one who ‘solves the riddle,’ but rather one who gets a lot of money to do so” [6]; “Watson’s book may contribute to the much-needed demythologization of modern science”; “with very few exceptions, it is not the men that make science; it is science that makes the men” [4].

That disappearing idealistic traditional order might be exemplified in Sinclair Lewis’s Arrowsmith. Published in 1925 by Harcourt, Brace, according to amazon.com there have been more than 80 later editions, including a 2008 paperback. Evidently the yearning remains strong for disinterested science for the public good. The book’s protagonist, after some early mis-steps and yieldings to commercial temptations, opts for pure research for the good of humankind. Even a couple of decades ago, an academic of my generation (a biochemist) told me that he still gave his graduate students Arrowsmith to read as a guide to the proper ethos of science.

That occasion for being reminded of Arrowsmith was a series of seminars I was then holding on our campus about ethics in research [7], a topic that was just becoming prominent as instances of dishonesty in scientific work were beginning to be noted with increasing frequency.

More about that in a future blog post.

I encountered ambitious young go-getters who luxuriated in the [then!] largesse of research support, inserting personal pleasures into publicly funded research travel, for example studying aspects of marine environments in ways that made possible scuba-diving and general cavorting in the Caribbean. I participated in the WETS, one of the informal associations of young up-and-comers who used to sample fleshly diversions as part of research-grant-paid trips to professional conferences
