Science is broken

Posted by Henry Bauer on 2017/11/21

Science is broken: Perverse incentives and the misuse of quantitative metrics have undermined the integrity of scientific research is the full title of an article published in the on-line journal AEON . I learned of it through a friend who was interested in part because the authors are at the university from which I retired some 17 years ago.

The article focuses on the demands on researchers to get grants and publish, and that their achievements are assessed quantitatively rather than qualitatively, through computerized scoring of such things as Journal Impact Factor and numbers of citations of an individual’s work.

I agree that those things are factors in what has gone wrong, but there are others as well.

The AEON piece is an abbreviated version of the full article in Environmental Engineering Science (34 [2017] 51-61; DOI: 10.1089/ees.2016.0223). I found it intriguing that the literature cited in it overlaps very little with the literature with which I’ve been familiar. That illustrates how over-specialized academe has become, and with that the intellectual life of society as a whole. There is no longer a “natural philosophy” that strives to integrate knowledge across the board, from all fields and specializations; and there are not the polymath public intellectuals who could guide society through the jungle of ultra-specialization. So it is possible, as in this case of “science is broken”, for different folk to reach essentially the same conclusion by extrapolating from quite different sets of sources and quite independently of one another.

I would add more factors, or perhaps context, to what Edwards and Roy emphasized:

The character of research activity has changed out of sight since the era or “modern science” began; for example, the number of wannabe “research universities” in the USA has tripled or quadrupled since WWII — see “Three stages of modern science”; “The science bubble”; chapter 1 in Science Is Not What You Think [McFarland 2017].

This historical context shows how the perverse incentives noted by Edwards and Roy came about. Honesty and integrity, dedication to truth-seeking above all, were notable aspects of scientific activity when research was something of an ivory-tower avocation; nowadays research is so integrated with government and industry that researchers face much the same difficulties as professionals who seek to practice honesty and integrity while working in the political realm or the financial realm: the system makes conflicts of interest, institutional as well as personal, inevitable. John Ziman (Prometheus Bound, Cambridge University Press) pointed out how the norms of scientific practice nowadays differ from those traditionally associated with science “in the good old days” (the “Mertonian” norms of communality, universality, disinterestedness, skepticism).

My special interest has long been in the role of unorthodoxies and minority views in the development of science. The mainstream, the scientific consensus, has always resisted drastic change (Barber, “Resistance by scientists to scientific discovery”, Science, 134 [1961] 596–602), but nowadays that resistance can amount to suppression; see “Science in the 21st century”; Dogmatism in Science and Medicine: How Dominant Theories Monopolize Research and Stifle the Search for Truth [McFarland, 2012]). Radical dissent from mainstream views is nowadays expressed openly almost only by long-tenured full professors or by retired people.

I’m in sympathy with the suggestions at the end of the formal Edwards and Roy paper, but I doubt that even those could really fix things since the problem is so thoroughgoingly systemic. Many institutions and people are vested in the status quo. Thus PhD programs will not change in the desired direction so long as the mentoring faculty are under pressure to produce more publications and grants, which leads to treating graduate students as cheap hired hands pushing the mentor’s research program instead of designing PhD research as optimum for neophytes to learn to do independent research. The drive for institutional prestige and status and rankings seems the same among university leaders, and they seek those not by excelling in “higher education” but by winning at football and basketball and by getting and spending lots of grant money on “research”. How to change that obsession with numbers: dollars for research, games won in sports?

That attitude is not unique to science or to academe. In society as a whole there has been increasing pressure to find “objective” criteria to avoid the biases inherent inevitably in human judgments. Society judges academe by numbers — of students, of research expenditures, of patents, of magnitude of endowment , etc. — and we compare nations by GDP rather than level of satisfaction among the citizens. In schools we create “objective” and preferably quantifiable criteria like “standards of learning” (SOLs), that supersede the judgments of the teachers who are in actual contact with actual students. Edwards and Roy cite Goodhart’s Law, which states that “when a measure becomes a target, it ceases to be a good measure”, which was new to me and which encapsulates so nicely much of what has gone wrong. For instance, in less competitive times, the award of a research grant tended to attest the quality of the applicant’s work; but as everything increased in size, and the amount of grants brought in became the criterion of quality of applicant and of institution, the aim of research became to get more grants rather than to do the most advancing work that would if successful bring real progress as well as more research funds. SOLs induced teachers to cheat by sharing answers with their students before giving the test. And so on and on. The cart before the horse. The letter of every law becomes the basis for action instead of the human judgment that could put into practice the spirit of the law.

Can truth prevail?

Posted by Henry Bauer on 2017/10/08

Recently I joined the Heterodox Academy, whose mission is to promote viewpoint diversity :

We are a politically diverse group of social scientists, natural scientists, humanists, and other scholars who want to improve our academic disciplines and universities.
We share a concern about a growing problem: the loss or lack of “viewpoint diversity.” When nearly everyone in a field shares the same political orientation, certain ideas become orthodoxy, dissent is discouraged, and errors can go unchallenged.
To reverse this process, we have come together to advocate for a more intellectually diverse and heterodox academy.

My personal focus for quite some time has been the lack of viewpoint diversity on scientific issues — HIV/AIDS, global warming, and a host of less prominent topics (see Dogmatism in Science and Medicine: How Dominant Theories Monopolize Research and Stifle the Search for Truth). But earlier I had been appalled — and still am — over political correctness, by which I mean the dogmatic assertion that certain sociopolitical views must not only prevail but must be enforced, including by government action.

I became aware of political correctness when it came to my university in the late 1980s (distinctly later than elsewhere) and led to the resignation of Alan Mandelstamm, a nationally renowned teacher (of economics) who had for more than a decade attracted more students to his classes than any other teacher of any subject, as well as having a variety of faculty members from other fields sit in on his classes purely for the learning experience. I’ve described the circumstances of Al’s resignation in a couple of articles (The trivialization of sexual harassment: Lessons from the Mandelstamm Case; Affirmative action at Virginia Tech: The tail that wagged the dog). Al passed away some years ago; his obituary has been funded to be permanent and the contributors to it testify to what a marvelous instructor Al was, to the benefit of untold numbers of individuals: 4 years after Al died, former students and associates who learn of his passing continue to add their recollections. Al and I had both participated in the Virginia chapter of the National Association of Scholars (NAS), which stands for traditional academic ideals:
NAS is concerned with many issues, including academic content, cost, unfairness, academic integrity, campus culture, attitudes, governance, and long-term trends. We encourage commitment to high intellectual standards, individual merit, institutional integrity, good governance, and sound public policy.

What that involves in practice is illustrated in the newsletter I edited until my retirement.

Common to NAS, the Heterodox Academy, and dissenting from dogmatism on HIV/AIDS, global warming, and many other issues is the belief that views and actions ought to be consonant with and indeed formed by the available evidence and logical inferences from it — by the truth, in other words, at least as close as humans can come to it at any given time.

Ideologies and worldviews can make it difficult for us even to acknowledge what the evidence is when it seems incompatible with our beliefs. Since my interest for many decades has been in unorthodoxies, I’ve looked into the evidence pertaining to a greater number of controversial issues, in more detail and depth, than most people have had occasion to, with the frustrating consequence that nowadays many of the people with whom I share the preponderance of sociopolitical preferences are not with me regarding HIV/AIDS or global warming; I’m the rare example of “A politically liberal global-warming skeptic”; and I wish that those who seem to agree with me did not include people whose sociopolitical views and actions are abhorrent to me (say, Ted Cruz or Jeff Sessions).

At any rate, in science and in the humanities and in politics, in all aspects of human life, the thing to aim for is to find the best evidence and to be guided by it. Through the Heterodox Academy I learned recently of the Pro-Truth Pledge; see “How to address the epidemic of lies in politics: The ‘Pro-Truth Pledge,’ based on behavioral science research, could be part of the answer”.

The badge of that pledge is now on my personal website, and I encourage others to join this venture.

 

I don’t expect quick results, of course, but “The journey of a thousand miles begins with one step” (often misattributed to Chairman Mao, but traceable more than a millennium further back to Lao Tzu or Laozi, founder of Taoism).

Scientific consensus vs. the evidence: Big-Bang theory and fudge factors

Posted by Henry Bauer on 2017/09/02

The scientific consensus is that the universe began in a “Big Bang” around 13 billion years ago.

As with the scientific consensus on most matters, the media and society at large treat this consensus as unquestionable truth. Serious and competent dissenters are almost invisible, and much of the media depict people who don’t accept the consensus as Flat-Earthers, crackpots.

Again as with the scientific consensus on many matters, the actual evidence, the facts, do not support the consensus unequivocally. Sorely missing from society’s respect for “science” is an appreciation of the difference between facts and theories.

Concerning the Big Bang, the facts are the differences in colors of the light emitted by the chemical elements as observed on Earth and on cosmic objects.

“Color” is the human sensation experienced when visible light of particular wavelengths (or frequencies, inversely proportional to wavelengths) hits the eye’s retina. A well established physical phenomenon is the Doppler Effect: an observer moving away from a source of waves registers a longer wavelength than an observer at the source itself (and vice versa, an observer traveling towards a source of waves registers an apparently shorter wavelength). The example typically given in schools, long ago in the days of steam-engine trains, was that the whistles from the train’s engine sounded a higher tone when the train was approaching the station and a lower note when moving away from the station; the Internet offers many illustrations of this, for example “Brass band on train demonstrates Doppler effect”.

All observations of distant cosmic objects show a “redshift”: the colors of light emitted by the chemical elements on the objects are shifted to longer wavelengths, to the red end of the spectrum of visible light. According to the Doppler Effect, that means the objects are moving away from Earth, in all directions; the universe is expanding, in other words.

However: Is the Doppler Effect the only possible reason for the cosmic redshifts?

No, according to observational evidence accumulated by astronomer Halton Arp, which suggests that the light emitted by quasars has a redshift that is only partly a Doppler Effect, the other part possibly characteristic of newly formed matter. Quasars are “quasi-stellar objects”, emitting much larger amounts of energy than would stars of apparently similar size, and they are key components in calculations of the distances and speeds of cosmic objects. If Arp was right, then Big-Bang cosmology might well be replaced by the Steady-State theory of the universe promoted by Fred Hoyle and others. Since quasars are far from fully understood (Frequently asked questions about Quasars ), Arp may turn out to have been right.

At any rate, that the scientific consensus on Big-Bang cosmology is almost universally accepted, that the common conventional wisdom has no doubts about it, illustrates how a scientific consensus can become popular public dogma even when there are substantive reasons to doubt its validity.

There are actually many reasons to doubt the validity of the Big-Bang hypothesis, set out for instance by the late Tom Van Flandern (The Top 30 problems with the Big Bang Theory) or more recently and succinctly by “Tanya Techie” (Top Ten scientific flaws in the Big Bang Theory).

What has seemed to me the kiss of death for Big-Bang Theory is the need for the fudge factors of “dark matter” and “dark energy” to explain the calculated rate of universe expansion; fudge factors that seem utterly absurd given that they are supposed to represent amounts much larger than the known amounts of normal matter and energy (Rethinking “Star Soup”) but have never actually been observed, they are postulated to exist solely to make Big-Bang Theory work.

An additional ground for doubt is that the calculations on which dark matter-energy are estimated appear to be seriously flawed: Donald G. Saari, “N-body solutions and computing galactic masses”, Astronomical Journal, 149 (2015) 174; “Mathematics and the ‘Dark Matter’ puzzle”, American Mathematical Monthly, 122 (2015) 407.

*                     *                   *                   *                   *                   *                   *                   *

Big-Bang Theory is far from alone as an almost universally accepted doctrine that in reality conforms only doubtfully with the actual evidence. Close examination of the actual facts on quite a number of other topics reveals that there are reasonable doubts about the validity of the scientific consensus on how to interpret the evidence about

Ø      the extinction of the dinosaurs

Ø      the mechanism of smell

Ø      the efficacy of anti-depressants

Ø      the cholesterol theory of cardiovascular disease

Ø      the blood-pressure theory of strokes and heart attacks

Ø      the cause of AIDS

Ø      when and from where the first human settled in the Americas

Ø      the hazards of second-hand tobacco smoke

Ø      whether nuclear fusion is feasible at ordinary temperatures (“cold fusion”)

Ø      whether human-generated carbon dioxide is responsible for climate change

Ø      whether continental drift (plate tectonics) adequately explains all the facts about earthquakes and other geological phenomena

Ø      the cause(s) of Alzheimer’s disease

Ø      the potential danger of mercury in vaccines and in dental amalgams

and more; see Dogmatism in Science and Medicine: How Dominant Theories Monopolize Research and Stifle the Search for Truth

Slowing of global warming officially confirmed — by reading between the lines

Posted by Henry Bauer on 2017/08/12

Climate-change skeptics, deniers, denialists, and also unbiased observers have pointed out that measured global temperatures seem to have risen at a slower rate, or perhaps ceased rising at all, since about 1998.
But the media have by and large reported the continuing official alarmist claims that each year has been the hottest on record, that a tipping point is nearly upon us, catastrophe is just around the corner — exemplified perhaps by Al Gore’s recent new film, An Inconvenient Sequel, with interviews of Gore in many media outlets.

However, that the pause in global warming is quite real is shown decisively by the way in which the mainstream consensus has tried to discount the facts, attempting to explain them away.
For example a pamphlet, published jointly by the Royal Society of London and the National Academy of Sciences of the USA, asserts that human-caused release of greenhouse gases is producing long-term warming and climate change, albeit there might be periods on the order of decades where there is no or little warming, as with the period since about 2000 when such natural causes as “lower solar activity and volcanic eruptions” have “masked” the rise in temperature (“Climate-Change Science or Climate-Change Propaganda?”).

That assertion misses the essential point: All the alarmist projections are based on computer models. The models failed to foresee the pause in temperature rise since 1998, demonstrating that the models are inadequate and therefore their projections are wrong. The models also fail to accommodate the period of global cooling rather than warming from the 1940s to the 1970s.

The crux is that the models do not incorporate important natural forces that affect the carbon cycle and the energy interactions. Instead, when the models are patently wrong, as from 1940s to 1970s and since 1998, the modelers and other researchers vested in the theory of human-caused climate change speculate about how one or other natural phenomenon somehow “masks” the asserted underlying temperature rise.

Above all, of course, the theorists neglect to mention that the Earth is still rebounding from the last Ice Age and will, if the last million years are any guide, continue to warm up for many tens of thousands of years (Climate-change facts: Temperature is not determined by carbon dioxide).
The various attempts to explain away the present pause in temperature rise were listed a few years ago at THE HOCKEY SCHTICK“Updated list of 66 excuses for the 18-26 year ‘pause’ in global warming — ‘If you can’t explain the ‘pause’, you can’t explain the cause’”.
Here are a few of the dozens of excuses for the failure of global temperature to keep up with projections of the climate models:

1. Lower activity of the sun
That ought to raise eyebrows about this whole business. Essentially all the energy Earth receives from out there comes from the Sun. Apparently the computer models do not start by taking that into account?
(Peter Stauning, “Reduced solar activity disguises global temperature rise”, Atmospheric and Climate Sciences, 4 #1, January 2014 “Without the reduction in the solar activity-related contributions the global temperatures would have increased steadily from 1980 to present”)
And of course if the Sun stopped shining altogether…
Anyway, the models are wrong.

2. The heat is being hidden in the ocean depths (Cheng et al., “Improved estimates of ocean heat content from 1960 to 2015”, Science Advances, 10 March 2017, 3 #3, e1601545, DOI: 10.1126/sciadv.160154
In other words, the models are wrong about the distribution of supposedly trapped heat.

3. Increased emission of aerosols especially in Asia (Kühn et al., “Climate impacts of changing aerosol emissions since 1996”, Geophysical Research Letters, 41 [14 July 2014] 4711–18, doi:10.1002/2014GL060349)
The climate models are wrong because they do not properly take aerosol emissions into account.

3a. “Volcanic aerosols, not pollutants, tamped down recent Earth warming, says CU study”
       In other words, the models are wrong because they cannot take into account the complexities of natural events that affect climate.

4. Reduced emission of greenhouse gases, following the Montreal Protocol eliminating ozone-depleting substances (Estrada et al, “Statistically derived contributions of diverse human influences to twentieth-century temperature changes”, Nature Geoscience, 6 (2013) 1050-55 doi:10.1038/ngeo1999
       The climate models are wrong because they do not take into account all greenhouse-gas emissions.

5. “Contributions of stratospheric water vapor to decadal changes in the rate of global warming” (Solomon et al., Science, 327 [2010] 1219-12;
DOI: 10.1126/science.1182488)
In other words, the models are wrong because they do not take account of variations in water vapor in the stratosphere.

6. Strengthened trade winds in the Pacific
Again, the models are wrong because they cannot take account of the innumerable natural phenomena that determine climate.

6a.     An amusing corollary is that “Seven years ago, we were told the opposite of what the new Matthew England paper says: slower (not faster) trade winds caused ‘the pause’”

And so on though another 50 or 60 different speculations. Although they are all different, there is a single commonality: The computer models used to represent Earth’s climate are woefully unable to do so. That might well be thought to be obvious a priori in view of the astronomical number of variables and interactions that determine climate. Moreover, a little less obviously perhaps, “global” climate is a human concept. The reality is that short- and long-term changes in climate by no means always occur in parallel in different regions.

Take-away points:

Mainstream climate science has demonstrated that
all the climate models are inadequate
and their projections have been wrong

Since the late 1990s, global temperatures have not risen
to the degree anticipated by climate models and climate alarmists
but that is not officially admitted
even as it is obvious from the excuses offered
for the failure of the models

What science says about global warming and climate change

Posted by Henry Bauer on 2017/07/06

There is strong evidence that global temperatures are not significantly dependent on the amount of carbon dioxide in the atmosphere (Climate-change facts: Temperature is not determined by carbon dioxide).

That’s what science — the evidence, the facts — says.

Nevertheless, the overwhelmingly widespread belief among public and governments is the opposite, believing carbon dioxide to be the single most important determinant of global temperature and climate.

How could such a disparity between fact and public belief come about?

President Eisenhower foresaw the possibility half a century ago:
“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” (Farewell speech, 17 January 1961).

Such influence of a scientific-technological elite is possible because “science” has become believed in superstitiously: on authority, not because it offers sound evidence and logic (Superstitious belief in science). A number of popular misunderstandings about science conspire to maintain this state of affairs, notably a failure to appreciate how drastically different scientific activities became following World War II, different from earlier times; science nowadays is not self-correcting and it does not follow the so-called scientific method. A full discussion of those points is in my just-published Science Is Not What You Think — How it has changed, Why we can’t trust it, How it can be fixed.

The “fix” refers to the possible establishment of a Science Court to adjudicate expert differences over technical issues. That was first suggested more than half a century ago when the experts were at loggerheads and arguing publicly over whether power could be generated safely using nuclear reactors.
More recently, some legal scholars have pointed out that such an institution could help the legal system to cope with cases where technical issues play an important role.
Beyond that, I suggest that a Science Court is needed to force the prevailing “scientific consensus” to respond substantively to critiques like those made by the many critics of human-caused global warming and climate change.

Vaccines: The good, the bad, and the ugly

Posted by Henry Bauer on 2017/05/21

Only in recent years have I begun to wonder whether there are reasons not to follow official recommendations about vaccination. In the 1930s, I had the then-usual vaccinations, including (in Austria, perhaps Europe) against smallpox. A few others in later years when I traveled quite a bit.

But the Andrew Wakefield affair *, and the introduction of Gardasil **, showed me that official sources had become as untrustworethy about vaccines as they have become about prescription drugs.

It seems that Big Pharma had just about run out of new diseases to invent against which to create drugs and had turned to snake-oil-marketing of vaccines. We are told, for example, that 1 in 3 people will experience shingles in their lifetime and should get vaccinated against it. Have one in three of your aged friends ever had shingles? Not among my family and friends. One of my buddies got himself vaccinated, and came down with shingles a couple of weeks later. His physician asserted that the attack would have been more severe if he hadn’t been vaccinated — no need for a control experiment, or any need to doubt official claims.

So it’s remarkable that the Swedish Government has resisted attempts to make vaccinations compulsory (“Sweden bans mandatory vaccinations over ‘serious health concerns’” by Baxter Dmitry, 12 May 2017).

That article includes extracts from an interview of Robert F. Kennedy, Jr., on the Tucker Carlson Show, which included such tidbits as the continued presence of thimerosal (organic mercury compound) in many vaccines including the seasonal flu vaccines that everyone is urged to get; and the huge increase in number of things against which vaccination is being recommended:

“I got three vaccines and I was fully compliant. I’m 63 years old. My children got 69 doses of 16 vaccines to be compliant. And a lot of these vaccines aren’t even for communicable diseases. Like Hepatitis B, which comes from unprotected sex, or using or sharing needles – why do we give that to a child on the first day of their life? And it was loaded with mercury.”

Superstitious belief in science

Posted by Henry Bauer on 2017/05/16

Most people have a very misled, unrealistic view of “science”. A very damaging consequence is that scientific claims are given automatic respect even when that is unwarranted — as it always is with new claims, say about global warming. Dramatic changes in how science is done, especially since mid-20th century, make it less trustworthy than earlier.

In 1987, historian John Burnham published How Superstition Won and Science Lost, arguing that modern science had not vanquished popular superstition by inculcating scientific, evidence-based thinking; rather, science had itself become on worldly matters the accepted authority whose pronouncements are believed without question, in other words superstitiously, by society at large.

Burnham argued through detailed analysis of how science is popularized, and especially how that has changed over the decades. Some 30 years later, Burnham’s insight is perhaps even more important. Over those years, certain changes in scientific activity have also become evident that support Burnham’s conclusion from different directions: science has grown so much, and has become so specialized and bureaucratic and dependent on outside patronage, that it has lost any ability to self-correct. As with religion in medieval times, official pronouncements about science are usually accepted without further ado, and minority voices of dissent are dismissed and denigrated.

A full discussion with source references, far too long for a blog post, is available here.

Climate-change orthodoxy: alternative facts, uncertainty equals certainty, projections are not predictions, and other absurdities of the “scientific consensus”

Posted by Henry Bauer on 2017/05/10

G. K. Chesterton once suggested that the best argument for accepting the Christian faith lies in the reasons offered by atheists and skeptics against doing so. That interesting slant sprang to mind as I was trying to summarize the reasons for not believing the “scientific consensus” that blames carbon dioxide for climate change.

Of course the very best reason for not believing that CO2 causes climate change are the data, as summarized in an earlier post

–>      Global temperatures have often been high while CO2 levels were low, and vice versa

–>     CO2 levels rise or fall after temperatures have risen or fallen

–>     Temperatures decreased between the 1940s and 1970s, and since about 1998 there has been a pause in warming, perhaps even cooling, while CO2 levels have risen steadily.

But disbelieving the official propaganda becomes much easier when one recognizes the sheer absurdities and illogicalities and self-contradictions committed unceasingly by defenders of the mainstream view.

1940s-1970s cooling
Mainstream official climate science is centered on models: computer programs that strive to simulate real-world phenomena. Any reasonably detailed description of such models soon reveals that there are far too many variables and interactions to make that feasible; and moreover that a host of assumptions are incorporated in all the models (1). In any case, the official models do not simulate the cooling trend of these three decades.
“Dr. James Hansen suspects the relatively sudden, massive output of aerosols from industries and power plants contributed to the global cooling trend from 1940-1970” (2).
But the models do not take aerosols into account; they are so flawed that they are unable to simulate a thirty-year period in which carbon emissions were increasing and temperatures decreasing. An obvious conclusion is that no forecast based on those models deserves to be given any credence.

One of the innumerable science-groupie web-sites expands on the aerosol speculation:
“40’s to 70’s cooling, CO2 rising?
This is a fascinating denialist argument. If CO2 is rising, as it was in the 40’s through the 70’s, why would there be cooling?
It’s important to understand that the climate has warmed and cooled naturally without human influence in the past. Natural cycle, or natural variability need to be understood if you wish to understand what modern climate forcing means. In other words modern or current forcing is caused by human industrial output to the atmosphere. This human-induced forcing is both positive (greenhouse gases) and negative (sulfates and aerosols).”

Fair enough; but the models fail to take account of natural cycles.

Rewriting history
The Soviet Union had an official encyclopedia that was revised as needed, for example by rewriting history to delete or insert people and events to correspond with a given day’s political correctness. Some climate-change enthusiasts also try to rewrite history: “There was no scientific consensus in the 1970s that the Earth was headed into an imminent ice age. Indeed, the possibility of anthropogenic warming dominated the peer-reviewed literature even then” (3). Compare that with a host of reproductions and citations of headlines from those cold times when media alarms were set off by what the “scientific consensus” indeed then was (4). And the cooling itself was, of course, real, as is universally acknowledged nowadays.

The media faithfully report what officialdom disseminates. Routinely, any “extreme” weather event is ascribed to climate change — anything worth featuring as “breaking news”, say tsunamis, hurricanes, bushfires in Australia and elsewhere. But the actual data reveal no increase in extreme events in recent decades: not Atlantic storms, nor Australian cyclones, nor US tornadoes, nor “global tropical cyclone accumulated energy”, nor extremely dry periods in the USA, in the last 150 years during which atmospheric carbon dioxide increased by 40% (pp. 46-51 in (1)). Nor have sea levels been rising in any unusual manner (Chapter 6 in (1)).

Defenders of climate-change dogma tie themselves in knots about whether carbon dioxide has already affected climate, whether its influence is to be seen in short-term changes or only over the long term. For instance, the attempt to explain 1940s-70s cooling presupposes that CO2 is only to be indicted for changes over much longer time-scales than mere decades. Perhaps the ultimate demonstration of wanting to have it both ways — only long-term, but also short-term — is illustrated by a pamphlet issued jointly by the Royal Society of London and the National Academy of Science of the USA (5, 6).

No warming since about 1998
Some official sources deny that there has been any cessation of warming in the new century or millennium. Others admit it indirectly by attempting to explain it away or dismiss it as irrelevant, for instance “slowdowns and accelerations in warming lasting a decade or more will continue to occur. However, long- term climate change over many decades will depend mainly on the total amount of CO2 and other greenhouse gases emitted as a result of human   activities” (p. 2 in (5)); “shorter-term variations are mostly due to natural causes, and do not contradict our fundamental understanding that the long-term warming trend is primarily due to human-induced changes in the atmospheric levels of CO2 and other greenhouse gases” (p. 11 in (5)).

Obfuscating and misdirecting
The Met Office, the UK’s National Meteorological Service, is very deceptive about the recent lack of warming:

“Should climate models have predicted the pause?
Media coverage … of the launch of the 5th Assessment Report of the IPCC has again said that global warming is ‘unequivocal’ and that the pause in warming over the past 15 years is too short to reflect long-term trends.

[No one disputes the reality of long-term global warming — the issue is whether natural forces are responsible as opposed to human-generated carbon dioxide]

… some commentators have criticised climate models for not predicting the pause. …
We should not confuse climate prediction with climate change projection. Climate prediction is about saying what the state of the climate will be in the next few years, and it depends absolutely on knowing what the state of the climate is today. And that requires a vast number of high quality observations, of the atmosphere and especially of the ocean.
On the other hand, climate change projections are concerned with the long view; the impact of the large and powerful influences on our climate, such as greenhouse gases.

[Implying sneakily and without warrant that natural forces are not “large and powerful”. That is quite wrong and it is misdirection, the technique used by magicians to divert attention from what is really going on. By far the most powerful force affecting climate is the energy coming from the sun.]

Projections capture the role of these overwhelming influences on climate and its variability, rather than predict the current state of the variability itself.
The IPCC model simulations are projections and not predictions; in other words the models do not start from the state of the climate system today or even 10 years ago. There is no mileage in a story about models being ‘flawed’ because they did not predict the pause; it’s merely a misunderstanding of the science and the difference between a prediction and a projection.
[Misdirection again. The IPCC models failed to project or predict the lack of warming since 1998, and also the cooling of three decades after 1940. The point is that the models are inadequate, so neither predictions nor projections should be believed.]

… the deep ocean is likely a key player in the current pause, effectively ‘hiding’ heat from the surface. Climate model projections simulate such pauses, a few every hundred years lasting a decade or more; and they replicate the influence of the modes of natural climate variability, like the Pacific Decadal Oscillation (PDO) that we think is at the centre of the current pause.
[Here is perhaps the worst instance of misleading. The “Climate model projections” that are claimed to “simulate such pauses, a few every hundred years lasting a decade or more” are not made with the models that project alarming human-caused global warming, they are ad hoc models that explore the possible effects of variables not taken into account in the overall climate models.]”

The projections — which the media (as well as people familiar with the English language) fail to distinguish from predictions — that indict carbon dioxide as cause of climate change are based on models that do not incorporate possible effects of deep-ocean “hidden heat” or such natural cycles as the Pacific Decadal Oscillation. Those and other such factors as aerosols are considered only in trying to explain why the climate models are wrong, which is the crux of the matter. The climate models are wrong.

Asserting that uncertainty equals certainty
The popular media disseminated faithfully and uncritically from the most recent official report that “Scientists are 95% certain that human are responsible for the ‘unprecedented’ warming experienced by the Earth over the last few decades

Leave aside that the warming cannot be known to be “unprecedented” — global temperatures have been much higher in the past, and historical data are not fine-grained enough to compare rates of warming over such short time-spans as mere decades or centuries.

There is no such thing as “95% certainty”.
Certainty means 100%; anything else is a probability, not a certainty.
A probability of 95% may seem very impressive — until it is translated into its corollary: 5% probability of being wrong; and 5% is 1 in 20. I wouldn’t bet on anything that’s really important to me if there’s 1 chance in 20 of losing the bet.
So too with the frequent mantra that 97% or 98% of scientists, or some other superficially impressive percentage, support the “consensus” that global warming is owing to carbon dioxide (7):

 

“Depending on exactly how you measure the expert consensus, it’s somewhere between 90% and 100% that agree humans are responsible for climate change, with most of our studies finding 97% consensus among publishing climate scientists.”

In other words, 3% (“on average”) of “publishing climate scientists” disagree. And the history of science teaches unequivocally that even a 100% scientific consensus has in the past been wrong, most notably on the most consequential matters, those that advanced science spectacularly in what are often called “scientific revolutions” (8).
Furthermore, “publishing climate scientists” biases the scales a great deal, because peer review ensures that dissenting evidence and claims do not easily get published. In any case, those percentages are based on surveys incorporating inevitable flaws (sampling bias as with peer review, for instance). The central question is, “How convinced are you that most recent and near future climate change is, or will be, the result of anthropogenic causes”? On that, the “consensus” was only between 33% and 39%, showing that “the science is NOT settled” (9; emphasis in original).

Science groupies — unquestioning accepters of “the consensus”
The media and countless individuals treat the climate-change consensus dogma as Gospel Truth, leading to such extraordinary proposals as that by Professor of Law, Philippe Sands, QC, that “False claims from climate sceptics that humans are not responsible for global warming and that sea level is not rising should be scotched by an international court ruling”.

I would love to see any court take up the issue, which would allow us to make defenders of the orthodox view attempt to explain away all the data which demonstrate that global warming and climate change are not driven primarily by carbon dioxide.

The central point

Official alarms and established scientific institutions rely not on empirical data, established facts about temperature and CO2, but on computer models that are demonstrably wrong.

Those of us who believe that science should be empirical, that it should follow the data and change theories accordingly, become speechless in the face of climate-change dogma defended in the manner described above. It would be screamingly funny, if only those who do it were not our own “experts” and official representatives (10). Even the Gods are helpless in the face of such determined ignoring of reality (11).

Climate-change facts: Temperature is not determined by carbon dioxide

Posted by Henry Bauer on 2017/05/02

The mainstream claims about carbon dioxide , global warming, and climate change, parroted by most media and accepted by most of the world’s governments, are rather straightforward: carbon dioxide released in the burning of “fossil fuels” (chiefly coal and oil) drives global warming because CO2 is a “greenhouse gas”, absorbing heat that would otherwise radiate harmlessly out into space. Since the mid-19th century, when the Industrial Revolution set off this promiscuous releasing of CO2, the Earth has been getting hotter at an unprecedented pace.

The trouble with these claims is that actual data demonstrate that global temperature is not determined by the amount of CO2 in the atmosphere.

For example, during the past 500 million years, CO2 levels have often been much higher than now, including times when global temperatures were lower (1):

“The gray bars at the top … correspond to the periods when the global climate was cool; the intervening white space corresponds to the warm modes … no correspondence between pCO2 and climate is evident …. Superficially, this observation would seem to imply that pCO2 does not exert dominant control on Earth’s climate …. A wealth of evidence, however, suggests that pCO2 exerts at least some control …. [but this Figure] … shows that the ‘null hypothesis’ that pCO2 and climate are unrelated cannot be rejected on the basis of this evidence alone.” [To clarify convoluted double negative: All the evidence cited in support of mainstream claims is insufficient to over-rule what the above Figure shows, that CO2 does not determine global temperatures (the “null hypothesis”).]

Again, with temperature levels in quantitative detail (2):

Towards the end of the Precambrian Era, CO2 levels (purple curve) were very much higher than now while temperatures (blue curve) were if anything lower. Over most of the more recent times, CO2 levels have been very much lower while temperatures most of the time were considerably higher.

Moreover, the historical range of temperature fluctuations makes a mockery of contemporary mainstream ambitions to prevent global temperatures rising by as much as 2°C; for most of Earth’s history, temperatures have been about 6°C higher than at present.

Cause precedes effect

The data just cited do not clearly demonstrate whether rising CO2 brings about subsequent rises in temperature — or vice versa. However, ice-core data back as far as 420,000 years do show which comes first: temperature changes are followed by CO2 changes (3):

On average, CO2 rises lag about 800 years behind temperature rises; and CO2 levels also decline slowly after temperatures have fallen.

Since the Industrial Revolution

Over the last 150 years, global temperatures have risen, and levels of CO2 have risen. This period is minuscule by comparison to the historical data summarized above. Crucially, what has happened in this recent sliver of time cannot be compared directly to the past because the historical data are not fine-grained enough to discern changes over such short periods of time. What is undisputed, however, is that CO2 and temperature have not increased in tandem in this recent era, just as over geological time-spans. From the 1940s until the 1970s, global temperatures were falling, and mainstream experts were telling the mass media that an Ice Age was threatening (4) — at the same time as CO2 levels were continuing their merry rise with fossil fuels being burnt at an ever-increasing rate (5):

1945 to 1977 cool period with soaring CO2 emissions. Global temperatures began to cool in the mid–1940’s at the point when CO2 emissions began to soar … . Global temperatures in the Northern Hemisphere dropped about 0.5°C (0.9° F)
from the mid-1940s until 1977 and temperatures globally
cooled about 0.2°C (0.4° F) …. Many of the world’s glaciers advanced during this time and recovered a good deal
of the ice lost during the 1915–1945 warm period”.

Furthermore (5):

Global cooling from 1999 to 2009. No global warming has occurred above the 1998 level. In 1998, the PDO [Pacific Decadal Oscillation] was in its warm mode. In 1999, the PDO flipped from its warm mode into its cool mode and satellite imagery confirms that the cool mode has become firmly entrenched since then and global cooling has deepened significantly in the past few years.”

In short:
–>       Global temperatures have often been high
while CO2 levels were low, and vice versa
–>        CO2 levels rise or fall after temperatures have risen or fallen
–>         CO2 levels have risen steadily but temperatures decreased
between the 1940s and 1970s, and since about 1998
there has been a pause in warming, perhaps even cooling

Quite clearly, CO2 is not the prime driver of global temperature. Data, facts, about temperature and CO2 demonstrate that something else has far outweighed the influence of CO2 levels in determining temperatures throughout Earth’s history, including since the Industrial Revolution. “Something else” can only be natural forces. And indeed there are a number of known natural forces that affect Earth’s temperature; and many of those forces vary cyclically over time. The amount of energy radiated to Earth by the Sun varies in correlation with the 11-year periodic cycle of sun-spots, which is fairly widely known; but there are many other cycles known only to specialists, say the 9-year Lunisolar Precession cycle; and these natural forces have periodically warmed and cooled the Earth in cycles of glaciation and warmth at intervals of roughly 100,000 – 120,000 years (the Milankovitch Cycles), with a number of other cycles superposed on those (6).

So the contemporary mainstream view, the so-called “scientific consensus”, is at odds with the evidence, the facts.

That will seem incredible to many people, who might well ask how that could be possible. How could “science” be so wrong?

In brief: because of facts about science that are not much known outside the ranks of historians and philosophers and sociologists of science (7): that the scientific consensus at any given time on any given matter has been wrong quite often over the years and centuries (8); and that science nowadays has become quite different from our traditional view of it (9).

The banality of evil — Psychiatry and ADHD

Posted by Henry Bauer on 2017/04/25

“The banality of evil” is a phrase coined by Hannah Arendt when writing about the trial of Adolf Eichmann who had supervised much of the Holocaust. The phrase has been much misinterpreted and misunderstood. Arendt was pointing to the banality of Eichmann, who “had no motives at all” other than “an extraordinary diligence in looking out for his personal advancement”; he “never realized what he was doing … sheer thoughtlessness … [which] can wreak more havoc than all the evil instincts” (1). There was nothing interesting about Eichmann. Applying Wolfgang Pauli’s phrase, Eichmann was “not even wrong”: one can learn nothing from him other than that evil can result from banality, from thoughtlessness. As Edmund Burke put it, “The only thing necessary for the triumph of evil is for good men to do nothing” — and not thinking is a way of doing nothing.

That train of thought becomes quite uncomfortable with the realization that sheer thoughtlessness nowadays pervades so much of the everyday practices of science, medicine, psychiatry. Research simply — thoughtlessly — accepts contemporary theory as true, and pundits, practitioners, teachers, policy makers all accept the results of research without stopping to think about fundamental issues, about whether the pertinent contemporary theories or paradigms make sense.

Psychiatrists, for example, prescribe Ritalin and other stimulants as treatment for ADHD — Attention-Deficit/Hyperactivity Disorder — without stopping to think about whether ADHD is even “a thing” that can be defined and diagnosed unambiguously (or even at all).

The official manual, which one presumes psychiatrists and psychologists consult when assigning diagnoses, is the Diagnostic and Statistical Manual of Mental Disorders (DSM), published by the American Psychiatric Association, now (since 2013) in its 5th edition (DSM-5). DSM-5 has been quite widely criticized, including by such prominent psychiatrists as Allen Frances who led the task force for the previous, fourth, edition (2).

Even casual acquaintance with the contents of this supposedly authoritative DSM-5 makes it obvious that criticism is more than called for. In DSM-5, the Diagnostic Criteria for ADHD are set down in five sections, A-E.

A: “A persistent pattern of inattention and/or hyperactivity-impulsivity that interferes with functioning or development, as characterized by (1) and/or (2):
     1.   Inattention: Six (or more) of the following symptoms have persisted for at least 6 months to a degree that is inconsistent with developmental level and that negatively impacts directly on social and academic/occupational activities
           Note: The symptoms are not solely a manifestation of oppositional behavior, defiance, hostility, or failure to understand tasks or instructions. For older adolescents and adults (age 17 and older), at least five symptoms are required.
a.     Often fails to give close attention to details or makes careless mistakes in schoolwork, at work, or during other activities (e.g., overlooks or misses details, work is inaccurate)
b.     Often has difficulty sustaining attention in tasks or play activities (e.g., has difficulty remaining focused during lectures, conversations, or lengthy reading).”
and so on through c-i, for a total of nine asserted characteristics of inattention.

Paying even cursory attention to these “criteria” makes plain that they are anything but definitive. Why, for example, are six symptoms required up to age 16 when five are sufficient at 17 years and older? There is nothing clear-cut about “inconsistent with developmental level”, which depends on personal judgment about both the consistency and the level of development. Different people, even different psychiatrists no matter how trained, are likely to judge inconsistently in any given case whether the attention paid (point “a”) is “close” or not. So too with “careless”, “often”, “difficulty”; and so on.

It is if anything even worse with Criteria A(2):

“2.    Hyperactivity and Impulsivity:
Six (or more) of the following symptoms have persisted for at least 6 months to a degree that is inconsistent with developmental level and that negatively impacts directly on social and academic/occupational activities
       Note: The symptoms are not solely a manifestation of oppositional behavior, defiance, hostility, or failure to understand tasks or instructions. For older adolescents and adults (age 17 and older), at least five symptoms are required.
a.    Often fidgets with or taps hands or feet or squirms in seat.”
and so on through b-i, for again a total of nine supposed characteristics of inattention. There is no need to cite any of those since “a” amply reveals the absurdity of designating as the symptom of a mental disorder a type of behavior that is perfectly normal for the majority of young boys. This “criterion” makes self-explanatory the reported finding that boys are three times more likely than girls to be diagnosed with ADHD, though experts make heavier weather of it by suggesting that sex hormones may be among the unknown causes of ADHD (3).

A(1) and (2) are followed by
“B. Several inattentive or hyperactivity-impulsivity symptoms were present prior to age 12 years.
C. Several inattentive or hyperactivity-impulsivity symptoms are present in two or more
settings  (e.g., at home, school, or work; with friends or relatives; in other activities).
D. There is clear evidence that the symptoms interfere with, or reduce the quality of, social,
academic, or occupational functioning.
E. The symptoms do not occur exclusively during the course of schizophrenia or another
psychotic disorder and are not better explained by another mental disorder (e.g., mood
disorder, anxiety disorder, dissociative disorder, personality disorder, substance
intoxication or withdrawal).”

It should be plain enough that this set of so-called criteria is not based on any definitive empirical data, as a simple thought experiment shows: What clinical (or any other sort of) trial could establish by observation that six symptoms are diagnostic up to age 17 whereas five can be decisive from that age on? What if the decisive symptoms were apparent for only 5 months rather than six; or five-and-three-quarters months? How remarkable, too, that “inattention” and hyperactivity and impulsivity” are both characterized by exactly nine possible symptoms.

Leaving aside the deplorable thoughtlessness of the substantive content of DSM-5, it is also saddening that something published by an authoritative medical society should reflect such carelessness or thoughtlessness in presentation. Competent copy-editing would have helped, for example by eliminating the many instances of “and/or”: “this ungraceful phrase … has no right to intrude in ordinary prose” (4) since just “or” would do nicely; if, for instance, I tell you that I’ll be happy with A or with B, obviously I’ll be perfectly happy also if I get both.
Good writing and proper syntax are not mere niceties; their absence indicates a lack of clear substantive thought in what is being written about, as Richard Mitchell ( “The Underground Grammarian”), liked to illustrate by quoting Ben Jonson: “Neither can his Mind be thought to be in Tune, whose words do jarre; nor his reason in frame, whose sentence is preposterous”.

At any rate, ADHD is obviously an invented condition that has no clearly measurable characteristics. Assigning that diagnosis to any given individual is an entirely subjective, personal judgment. That this has been done for some large number of individuals strikes me as an illustration of the banality of evil. Countless parents have been told that their children have a mental illness when they are behaving just as children naturally do. Countless children have been fed mind-altering drugs as a consequence of such a diagnosis. Some number have been sent to special schools like Eagle Hill, where annual tuition and fees can add up to $80,000 or more.

Websites claim to give information that is patently unfounded or wrong, for example:

“Researchers still don’t know the exact cause, but they do know that genes, differences in brain development and some outside factors like prenatal exposure to smoking might play a role. … Researchers looking into the role of genetics in ADHD say it can run in families. If your biological child has ADHD, there’s a one in four chance you have ADHD too, whether it’s been diagnosed or not. … Some external factors affecting brain development have also been linked to ADHD. Prenatal exposure to smoke may increase your child’s risk of developing ADHD. Exposure to high levels of lead as a toddler and preschooler is another possible contributor. … . It’s a brain-based biological condition”.

Those who establish such websites simply follow thoughtlessly, banally, what the professional literature says; and some number of academics strive assiduously to ensure the persistence of this misguided parent-scaring and children-harming. For example, by claiming that certain portions of the brains of ADHD individuals are characteristically smaller:

“Subcortical brain volume differences in participants with attention deficit hyperactivity disorder in children and adults: a cross-sectional mega-analysis” by Martine Hoogman et al., published in Lancet Psychiatry (2017, vol. 4, pp. 310–19). The “et al.” stands for 81 co-authors, 11 of whom declared conflicts of interest with pharmaceutical companies. The conclusions are stated dogmatically: “The data from our highly powered analysis confirm that patients with ADHD do have altered brains and therefore that ADHD is a disorder of the brain. This message is clear for clinicians to convey to parents and patients, which can help to reduce the stigma that ADHD is just a label for difficult children and caused by incompetent parenting. We hope this work will contribute to a better understanding of ADHD in the general public”.

An extensive detailed critique of this article has been submitted to the journal as a basis for retracting that article: “Lancet Psychiatry Needs to Retract the ADHD-Enigma Study” by Michael Corrigan & Robert Whitaker. The critique points to a large number of failings in methodology, including that the data were accumulated from a variety of other studies with no evidence that diagnoses of ADHD were consistent or that controls were properly chosen or available — which ought in itself be sufficient reason not to find publication.

Perhaps worst of all: Nowhere in the article is IQ mentioned; yet the Supplementary Material contains a table revealing that the “ADHD” subjects had on average higher IQ scores than the “normal” controls. “Now the usual assumption is that ADHD children, suffering from a ‘brain disorder,’ are less able to concentrate and focus in school, and thus are cognitively impaired in some way. …. But if the mean IQ score of the ADHD cohort is higher than the mean score for the controls, doesn’t this basic assumption need to be reassessed? If the participants with ADHD have smaller brains that are riddled with ‘altered structures,’ then how come they are just as smart as, or even smarter than, the participants in the control group?”

[The Hoogman et al. article in many places refers to “(appendix)” for details, but the article — which costs $31.50 — does not include an appendix; one must get it separately from the author or the journal.]

As usual, the popular media simply parroted the study’s claims, illustrated by headlines cited in the critique:

And so the thoughtless acceptance by the media of anything published in an established, peer-reviewed journal contributes to making this particular evil a banality. The public, including parents of children, are further confirmed in the misguided, unproven, notion that something is wrong with the brains of children who have been designated with a diagnosis that is no more than a highly subjective opinion.

The deficiencies of this article also illustrate why those of us who have published in peer-reviewed journals know how absurd it is to regard “peer review” as any sort of guarantee of quality, or even of minimal standards of competence and honesty. As Richard Horton, himself editor of The Lancet, has noted, “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” (5).

The critique of the Hoogman article is just one of the valuable pieces at the Mad in America website. I also recommend highly Robert Whitaker’s books, Anatomy of an Epidemic and Mad in America.
