Decision regarding complaints
against Bjorn Lomborg
1. The cases and their consideration
During the first quarter of 2002 the Danish Committees on
Scientific Dishonesty (UVVU, or DCSD in English) received
three complaints about Bjørn Lomborg (BL):
Case I: On 21 February 2002 DCSD received a complaint
from Mr Kåre Fog, MSc, PhD, a biologist (Case No.
612-02-0001)
Case II: On 7 March 2002 DCSD received a complaint from
Ms Mette Hertz & Mr Henrik Stiesdal (Case No.
612-02-0002)
Case III: On 22 March 2002 DCSD received a
complaint from Messrs Stuart Pimm & Jeffrey Harvey (Case
No. 612-02-0004).
DCSD has adhered to customary preliminary investigation
practice and has obtained the written contributions of the
parties in accordance with Section 4, subs. 2 of the Rules of
Procedure for the Danish Committees on Scientific
Dishonesty.
Furthermore, on 22 November 2002, DCSD received a complaint
from Dr Torben Stockfleth Jørgensen, DPhil. In view of the
consideration being given to the other complaints, however,
this complaint was received so late on that it has not been
subject to separate consideration. The complainant will
receive a copy of the present ruling, which is deemed to be
adequate at general level, also in relation to his
complaint.
The complaints about scientific dishonesty were directed at
Bjørn Lomborg's book "The Skeptical Environmentalist",
Cambridge University Press, 2001. The complaints include
many counts and deliberations. Following the round of
consultative comments from interested parties, the cases
considered include a total of 656 pages (Case I: 378 pages,
Case II: 143 pages and Case III: 135 pages).
DCSD discussed the three cases at a joint meeting of all
DCSD's committees on Tuesday, 11 June 2002. Discussions at the
meeting centred mainly on whether or not the book "The
Skeptical Environmentalist" should be classified as
science. A number of DCSD members stated that the book fails
to meet the customary requirements of science and that DCSD
ought therefore not to deal with the case. Other members
thought that the term "bad science" should not be an obstacle
to a complaint being admitted for consideration by DCSD.
It was decided to form a working party under DCSD with an
eye to reviewing the extensive material and considering
whether a book of this nature can warrant an assessment of
scientific dishonesty on the basis of the standards otherwise
applied to scientific works. The Working Party was made up as
follows:
Dr Nils Axelsen, MD, consultant, head of department
(Chairman) Professor Finn Collin, DPhil Professor Jørgen
Dalberg-Larsen, LLD Professor Arne Helweg, DSc (Agronomy),
research professor Professor Margareta Järvinen,
DPolSci
In September 2002 the working party submitted its report.
DCSD's three committees considered the case at joint meetings
on 9 October and 10 December 2002.
2. The Working Party's examination of "The Skeptical
Environmentalist"
"The Skeptical Environmentalist" is published by
Cambridge University Press, 2001. The book is more than 500
pages in length, as well as including 25 chapters, divided
into Parts I-VI, notes totalling 2,930 numbers and more than
1,800 references (bibliography). Combined, the notes and
bibliography take up 152 pages. The book has 173 figures and 9
tables. The Danish version, entitled "Verdens sande
tilstand" (literally: "The True State of the World") is
included in the Department of Political Science's list of
publications in the University of Aarhus's 1998 annual report,
the English-language version being listed as a monograph under
the Department's research publications for the year 2001.
The contents of "The Skeptical Environmentalist" can
be briefly summarized as follows:
Part I, The Litany (klagesang), describes how
one of the sources of the litany is the Worldwatch Institute's
annual reports, "The State of the World", which have
appeared since 1984. One of the protagonists in the criticism
of the Worldwatch Institute is Lester Brown of the Earth
Policy Institute. Bjørn Lomborg does not feel that this and
other institutions live up to their objectives and points out
that the premises, the facts, must be set straight. That is
what he has set out to do in this book.
Part II, Human Welfare, examines the size of the
world's population and its development, life expectancy and
health, food and hunger, and prosperity. It is concluded that
there has never been such a great degree of prosperity as now.
Part III, Can Human Prosperity Continue?, discusses
the prospects of having sufficient future resources: food,
forests, energy, non-energy resources and water. It is
concluded that there are enough resources for continued
prosperity.
Part IV, Pollution, Does it Undercut Human
Prosperity?, examines air pollution, acid rain and forest
death, indoor air pollution, water pollution and waste. It is
concluded that the pollution burden has diminished.
Part V, Tomorrow's Problems, examines chemicals,
biodiversity and global warming. It is concluded that the fear
of chemicals and reduction of species is exaggerated, and that
the colossal sums it is planned to deploy on reducing global
warming will be money ill spent.
Part VI, The Real State of the World, is introduced
thus: "Throughout this book I have tried to present all the
facts, to give us a rounded feel of the real state of the
world, and I have tried to compare and contrast it to our
current understanding, stemming from the recurrent
incantations of the Litany". The message is that priorities
must be assigned and that prioritization must be done on the
basis of facts. Cost-benefit analyses must be established.
Being overly optimistic is not without its costs, but being
overly pessimistic is very expensive. The book concludes:
"Thus, this is the very message of the book: Children born
today - in both the industrialized world and developing
countries - will live longer and be healthier. They will get
more food, a better education, a higher standard of living,
more leisure time and far more possibilities - without the
global environment being destroyed. And that is a beautiful
world".
3. The Working Party's reproduction of the professional
published critique of "The Skeptical Environmentalist" prior
to the complaints to DCSD
"The Skeptical Environmentalist" has given rise to
extensive public discussion and debate, both in Denmark and
internationally. There have been enthusiastic reviews in some
of the world's top newspapers such as the Washington Post and
the New York Times, and in The Economist.
The magazine Scientific American asked four leading experts
to assess Bjørn Lomborg's treatment of their own fields:
global warming, energy, population and biodiversity, devoting
11 pages to this in January 2002.
Stephen Schneider: "Global Warming, Neglecting the
Complexities" Schneider is a particularly
respected researcher who has been discussing these problems
for 30 years with thousands of fellow scientists and policy
analysts in myriad articles and formal meetings.
Most of Bjørn Lomborg's quotes allude to secondary
literature and media articles. Bjørn Lomborg uses
peer-reviewed articles only when they support his
rose-coloured point of view. By contrast, the authors on the
Intergovernmental Panel on Climate Change (IPCC) were
subjected to three rounds of audits by hundreds of external
experts.
Bjørn Lomborg employs no clear and discrete distinction
between various forms of probabilities. He makes frequent use
of the word "plausible" but, strangely for a statistician, he
never attaches any probability to what is "plausible". IPCC
gives a large "range" for the majority of projections, but
Bjørn Lomborg selects the least serious outcomes.
Stephen Schneider then provides a specific criticism of
Bjørn Lomborg's four main arguments:
1. Climate Science: Bjørn Lomborg quotes an article in
Nature (from the Hadley Center, 1989), uncritically and
without the authors' caveats. BL quotes Lindzen's
controversial "iris effect" as evidence that IPCC's climate
range needs to be reduced by a factor of almost three. BL
either fails to understand this mechanism or else omits to
state that the data stem from only a few years' data in a
small part of a single ocean. Extrapolating this sample to the
entire globe is wrong. Similarly, he quotes a controversial
Danish paper claiming that solar magnetic events can modulate
cosmic radiation and produce a clear connection between global
low-level cloud cover and incoming cosmic rays as an
alternative to CO2 in order to explain climate
change. The reason IPCC discounts this theory is "that its
advocates have not demonstrated any radiative forcing
sufficient to match that of much more parsimonious theories,
such as anthropogenic forcing."
2. Emissions scenarios: Bjørn Lomborg assumes that over
the next several decades, improved solar machines and other
new technologies will crowd fossil fuels off the market, which
will be done so efficiently that the IPCC scenarios vastly
overestimate the chance of major increases in CO2.
This is not so much analysis as wishful thinking contingent on
policies capable of reinforcing the incentives for such
development, and BL is opposed to such policies. No credible
analyst can just assert that a fossil-fuel-intensive scenario
is not "plausible" and, typically, BL gives no probability
that this might occur.
3. Cost-benefit calculations: Bjørn Lomborg's most
egregious distortions and feeblest analyses are his citations
of cost-benefit calculations. First, he chides the governments
that modified the penultimate draft of the IPCC report. But
there was a reason for that modification, which downgraded
aggregate cost-benefit studies: these studies fail to consider
so many categories of damage held to be important by political
leaders, and it is therefore not the "total cost-benefit"
analysis that Bjørn Lomborg wants. Again, BL cites only a
single value for climate damage - 5 trillion dollars -
although the same articles indicate that climate change can
vary from benefits to catastrophic losses. It is precisely
because the responsible scientific community cannot rule out
catastrophic outcomes at a high level of confidence that
climate mitigation policies are seriously proposed. For some
inexplicable reasons, BL fails to provide a range of climate
damage avoided, only a range for climate policy costs. This
estimate is based solely on the economics literature but
ignores the findings of engineers and does not take into
account pre-existing market imperfections such as
energy-inefficient machinery, houses and processes. Thus, five
US Dept. of Energy laboratories have suggested that such a
substitution can actually reduce some emissions at below-zero
costs.
4. The Kyoto Protocol: Bjørn Lomborg's invention of a
100-year regime for the Kyoto Protocol is a distortion of the
climate policy process. Most analysts know that "an extended"
Kyoto Protocol cannot deliver the 50% reduction in CO2
emissions needed to prevent large increases at the end
of the 21st century and during the 22nd century, and that
developed and developing countries alike will have to
cooperate to fashion cost-effective solutions over time. Kyoto
is a starting point, and yet with his 100-year projection BL
would squash even this first stage.
Bjørn Lomborg's book is published by the social sciences
side of Cambridge University Press. It is no wonder, then,
that the reviewers failed to spot BL's unbalanced presentation
of the natural science. It is a serious omission on the part
of an otherwise respected publishing house that
natural-science researchers were not taken on board. "Lomborg
admits, 'I am not myself an expert as regards ENVIRONMENTAL
PROBLEMS' - truer words are not found in the rest of the
book".
John P. Holdren: "Energy: Asking the Wrong
Questions" Bjørn Lomborg's chapter on energy
covers a scant 19 pages and is devoted almost entirely to
attacking the belief that the world is running out of energy,
a belief that BL appears to regard as part of the
"environmental litany". But only a handful of environmental
researchers, if any at all, believe this today. Conversely,
what they do say about this topic is that we are not running
out of energy, but out of environment, i.e. the capacity of
air, water, soil and biota to absorb, without intolerable
consequences for human well-being, the effects of energy
extraction, transport, energy transformation and energy use.
They also say that we are running out of the ability to manage
other risks of the energy supply, such as overdependence on
Middle East oil and the risk of nuclear energy systems leaking
weapons materials and expertise into the hands of
proliferation-prone nations or terrorists. This has been the
position of the environmental researchers for decades (e.g.
from 1971, 74, 76 and 77).
So whom is BL so resoundingly refuting with his treatise on
the abundance of world energy resources? The professional
analysts have not been arguing that the world is running out
of energy, only that the world could run out of cheap oil.
BL's dismissive rhetoric notwithstanding, this is not a silly
question, nor one with an easy answer.
Oil is currently the most valuable of the conventional
fossil fuels that have long provided the bulk of the world's
energy, including almost all energy for transport. The
quantity of recoverable oil resources is thought to be far
less than coal and nnatural gas, and those reserves are
located in the politically volatile Middle East. Much of the
rest is located offshore and in other difficult and
environmentally fragile areas. There is, accordingly, a
serious technical literature, produced mainly by geologists
and economists, exploring the questions of when world oil
production will peak and begin to decline, and what the price
might be in 2010, 2030 or 2050 - with considerable
disagreement among informed professionals.
BL seems not to recognize that the transition from oil to
other sources will not necessarily be a smooth one or occur at
prices as low as the price of oil today. BL shows no sign of
understanding why there is real debate about this among
serious-minded people.
BL offers no explanation of the distinction between "proved
reserves" and "remaining ultimately recoverable resources",
nor of the fact that the majority of the latter category is
located in the Middle East, but placidly informs us that it is
"imperative for our future energy supply that this region
remains reasonably peaceful" - as if that observation does not
undermine any basis for complacency.
BL is right in his basic proposition that the resources of
oil, oil shale, nuclear fuels and renewable energy are
immense. But that is disputed by only few environmental
researchers-and no well-informed ones. But his handling of the
technical, economic and environmental factors that will govern
the circumstances and quantities in which these resources
might actually be used is superficial, muddled and often plain
wrong. His mistakes include apparent misreadings and
misunderstandings of statistical data, the very kinds of
errors he claims are pervasive in the writings of
environmentalists. By the same token, there are other
elementary blunders of a type that should not be committed by
any self-respecting statistician. Thus, it is wrong that
measures in the developed countries have eliminated the vast
majority of SO2 and NO2 from smoke from
coal-burning facilities: it is only a minor proportion. Other
examples are given, and when it comes to nuclear energy,
plutonium is such a great security problem as regards the
potential production of nuclear weapons that it may preclude
use of the "breeding" approach unless a new technology is
invented that is just as cheap.
BL uses precise figures, where there is no basis for such,
and he produces assertions based on single citations and
without detailed elaborations, which is far from
representative of the literature.
Most of what is problematic about the global energy picture
is not covered by BL in the chapter on energy but in the
chapters dealing with air pollution, acid rain, water
pollution and global warming. The latter has been
devastatingly critiqued by Schneider.
There is no space to deal with the other energy-related
chapters, but their level of superficiality, selectivity and
misunderstandings is roughly consistent with what has been
reviewed here.
"Lomborg is giving skepticism - and statisticians - a bad
name."
John Bongaarts: "Population: Ignoring Its Impact"
Bjørn Lomborg's view that the number of people is not the
problem is simply wrong. The global population growth rate has
declined slowly, but absolute growth remains close to the very
high levels observed in past decades. Any discussion of global
trends is misleading without taking account of the enormous
contrasts between world regions, where the poorest nations of
Africa, Asia and Latin America have rapidly growing and young
populations, whereas Europe, North America and Japan have
virtually zero, and in some cases even negative, growth. As a
consequence, all future growth will be concentrated in the
developing countries, where four-fifths of the world's
population lives: from 4.87 to 6.72 billion between 2000 and
2025, or just as large as the record-breaking increase in the
past quarter of the (21st) century. This growth in the poorest
parts of the world continues virtually unabated. The growth
has led to high population density in many countries, but BL
dismisses concerns about this issue, based on a simplistic and
misleading calculation of density as the ratio of people to
land. In Egypt this would make 88/km2, but
deducting the uncultivated and unirrigated part of Egypt, it
makes 2,000/km2 - no wonder Egypt has to import
foodstuffs! Measured correctly, population densities have
reached extremely high levels, particularly in large countries
in Asia and the Middle East. This makes demands in terms of
agricultural expansion on more difficult, hitherto untilled
terrain, increased water consumption and a struggle for the
scarce water resources between households, industry and
farming. The upshot will be to make growth in food production
more expensive to achieve. BL's view that increased food
production is a non-issue rests heavily on the fact that
foodstuffs are cheap; but BL overlooks the fact that it is
large-scale subsidies to farmers, particularly in the
developed countries, that keep prices artificially low.
Appreciably expanding farming will result in a reduction of
woodland areas, loss of species, soil erosion, and pesticide
and fertilizer run-offs. Reducing this impact is possible but
costly, and would be easier if the growth in population were
slower.
BL overlooks the fact that population growth contributes to
poverty. First, children have to be fed, housed, clothed and
educated - while economically non-productive - then jobs have
to be created once they reach adulthood. Unemployment lowers
wages to subsistence level. Counteracting population growth
has fuelled "economic miracles" in a number of East Asian
countries.
BL overlooks the fact that the favourable trend in life
expectancy is due to intensive efforts on the part of
governments and the international community, but despite this,
800 million are still malnourished and 1.2 billion are living
in abject poverty. Population is not the main cause of the
world's social, economic and environmental problems, but it is
a substantial contributory factor. If future growth can be
slowed down, future generations would be better
off.
Thomas Lovejoy: "Biodiversity: Dismissing Scientific
Progress" In less than a page, Bjørn Lomborg discounts
the value of biodiversity both as a library for the life
sciences and as a provider of ecosystem services (partly due
to the general absence of markets for these services). When he
does get round to extinction, he confounds the process by
which a species is judged to have been made extinct with
estimates and projections of extinction rates. In contrast to
BL's claim, the loss of species from habitat remnants is a
widely documented phenomenon. A number of factual errors are
highlighted. BL takes particular exception to Norman Myer's
1979 estimate that 40,000 species are being lost every year,
failing to acknowledge that Myer deserves credit for being the
first to point out that the number was large and at a time
when it was difficult to do so accurately. Current estimates
are given in terms of the increases over normal extinction
rates. BL cynically spurns this method, because such estimates
sound more ominous. Instead, he ought to acknowledge that this
method is an improvement in the science. These rates are
currently 100 to 1,000 times' the normal, and are certain to
rise as natural habitats continue to dwindle.
The chapter on acid rain is equally poorly researched and
presented. BL establishes that acid rain has nothing to do
with urban pollution, though it is a fact that nitrogen
compounds (NOx) from traffic are a major source. Errors are
pointed out in BL's view of acid rain on forests.
The chapter on forests suffers from BL not knowing that
FAO's data are marred by the weight of so many different
definitions and methods that any statistician should know they
are not valid in terms of a time series. There are errors in
the figures from Indonesia in 1997. BL confuses forests with
tree plantations, and asserts that the only value of forests
is harvestable trees. That is analogous to valuing computer
chips for their silicon content only.
It is important to know that while deforestation and acid
rain are reversible, extinction of species is not.
BL entirely overlooks the fact that environmental
scientists identify a problem, posit hypotheses, test them
and, having reached their conclusions, suggest remedial
policies. By focusing on the first and last stages in this
process, BL implies incorrectly that all environmentalists do
is exaggerate.
Continued discussion between BL and the critics in
Scientific American Bjørn Lomborg, in his replies to
the scientists mentioned, accepts virtually nothing of the
full-scale criticism levelled at him. On Scientific American's
homepage (15 April 2002) John Rennie and John
Holdren presented a powerful rebuttal of Bjørn Lomborg's
replies to Scientific American's examination of the four
topics, also including a critique of BL's style of argument.
This is how Holdren's rejection is set out under the
headings:
"Misrepresenting what I wrote, Obfuscating what he wrote,
Persistent conceptual confusions, Vagueness where specificity
was required, Illusory precision where only approximations are
possible, Concluding observation"
Time Magazine devotes 60 pages on 2 September 2002 to a
series of articles under the heading "How to Preserve the
Planet and Make This a Green Century". Bjørn Lomborg's book is
referred to on page 58 under the heading "Danish darts.
Reviled for sticking it to the ecological dogma. Bjorn [sic]
Lomborg laughs all the way to the bank." It says the following
about the scientific critique: "Some scientists say they
initially hoped to ignore Lomborg, but in the wake of this
book's popularity have reacted with a fury rarely seen in
academia. Peter Raven, chairman of the American Association
for the Advancement of Science, calls Lomborg 'the prime
example in our time of someone who distorts statistics and
statements to meet his own political end.' A dozen esteemed
scientists, including Raven and Harvard's Edward O. Wilson,
are demanding that Lomborg's publisher cut him loose. 'We are
deeply disturbed that Cambridge University Press would publish
and promote an error-filled, poorly referenced and
non-peer-reviewed work', they write in a letter calling on
Cambridge to transfer publishing rights to a popular,
nonscholarly press."
The Working Party concludes its examination of the
criticism thus: The topics dealt with by Bjørn
Lomborg's book are of great social import and hence of
corresponding political interest. It is the view of the
Working Party that the many, particularly American
researchers, who have received Bjørn Lomborg's book with great
gusto, even in a specifically negative fashion, are unlikely
to have even given the book the time of day unless it had
received such overwhelmingly positive write-ups in leading
American newspapers and in The Economist. The USA is the
society with the highest energy consumption in the world, and
there are powerful interests in the USA bound up with
increasing energy consumption and with the belief in free
market forces. The USA is also responsible for a substantial
part of the research into this and other areas dealt with by
Bjørn Lomborg.
Bjørn Lomborg claims that he has presented all the
facts and has substantiated this with a large body of notes
and a bulky bibliography. The exchanges of views between Bjørn
Lomborg and his critics are technical, scientific and
scholarly in content. What is not usual in "common"
specialist-scientific discussion is Bjørn Lomborg's personal
attacks and apparent inability to take part in such a
discussion, cf. the critique of BL's style of argument and of
the fact that he, so to speak, accepts nothing of the massive
criticism.
Apart from the unusually widespread professional
disagreement with Bjørn Lomborg, the critics are offended at
his belittling a number of researchers and lumping researchers
together with environmental activists, parts of the serious
scientific research community at any rate being accused of
having misunderstood the relevant concepts, of misrepresenting
relevant facts, of understating uncertainties, of
cherry-picking data and of not acknowledging errors when these
had been proven - in a nutshell, at members of the research
community being guilty of large-scale infractions of the
researchers' code of conduct.
4. The Working Party's examination of the three
complaints
In the three complaints, BL is accused of fabricating data,
selectively and surreptitiously discarding unwanted results,
of the deliberately misleading use of statistical methods,
consciously distorted interpretation of the conclusions,
plagiarization of others' results or publications, and
deliberate misrepresentation of others' results. Together, the
three complaints cover the bulk of the chapters in Bjørn
Lomborg's book. In Case III Stuart Pimm and Jeffrey Harvey
use an extensive portion of the published criticism, including
the Scientific American discussion, as a basis for their
complaint.
In his replies, BL dismisses practically all the counts on
which he offers his position, but as with the discussion in
Scientific American, his rebuttals are not accepted by the
complainants.
5. The Working Party's deliberations on the scientific
process and dissemination of scientific results to the
public
The scientific process In the report that formed the
basis for the creation of DCSD in the health science domain,
the following brief description of the scientific process was
given:
"The result of scientific work is knowledge, cognition,
in the form of notions, assumptions and hypotheses
about 'the correct correlation between things'. Given that
the point of the exercise is to broaden our knowledge, the
actual core of science is the critical reasoning conducted in
the scientific literature, based on documented observations.
By virtue of this process, it is decided whether new ideas can
withstand massive criticism and be declared sound, and whether
less sustainable ideas should be sidelined."
The best quality control is achieved when science is
published in scientific journals. These are prolific in number
and, particularly within health and natural science, output is
high. Every specialist discipline has a kind of hierarchy of
journals, and special interest and attention attaches to those
located at the top end of the range in terms of scholarly
scientific quality. High quality is statistically correlated
with the stringent requirements imposed on the manuscripts
submitted with the aid of their adjudicators, referees who
provide the authors with pointed, critical counterthrust. A
manuscript will often pass back and forth several times, with
the possible addition of new observations and lines of
reasoning, before a final editorial stance is taken on
publication or rejection. The referee system is a mainstay of
the scientific world. So it is with good reason that
researchers ascribe great importance to where a scientific
paper has been published.
Dissemination of scientific results to the
public Safeguarding the public's legitimate interest in
being kept informed of progress in research is the ongoing
subject of many deliberations in many scientific fora and on
the editorial boards of many journals etc.
It is out of keeping with good scientific practice for a
researcher to publish by bypassing specialist academic fora,
i.e. to notify news media of a result that has not yet been
subjected to professional scrutiny in the customary fashion.
Good journals make publication conditional on no such form of
publication having taken place. It is in the interest of all
parties that these simple guidelines be followed in order to
deter unclear, unreliable or possibly misleading information
from being disseminated to the public, thus ensuring that the
public debate and any potential political consequences rest on
a foundation that is as sure-footed and substantial as
possible.
Furthermore, when researchers make statements to the press
about research results, their opinions are often ascribed
greater importance than those of non-researchers, regardless
of whether such statements relate to topics remote from their
own area of expertise and in which they therefore have no
qualified opinion to match their formal position and any
academic degree they may hold. This requires researchers not
to misuse their title and position in communications with the
public.
6. The Working Party's recommendation to
DCSD
Against the backdrop of their review of the material, the
Working Party has discussed the question on which DCSD had
directed it to take up a position:
Can a book of this nature warrant an evaluation of
scientific dishonesty on the basis of the standards otherwise
applied to scientific works?
No consensus on the Working Party was forthcoming in its
reply to this question, as some members of the Working
Party argued that the book is not science/research but
in its manifest onesidedness gives the appearance of a topical
debate-generating book, while other members of the
Working Party argued that the book has been
presented and, in wide circles including the scientific
community, perceived as research/science and must therefore be
assessed in accordance with scientific standards, i.e. be
examined on its individual merits in accordance with the
Executive Order on the Danish Committees on Scientific
Dishonesty.
7. DCSD's consideration of the complaints
As already mentioned, there has been extremely extensive
correspondence during DCSD's deliberation of the matter.
Rather than record this in detail, DCSD has deemed it fit to
present not only the Working Party's summary but the
complaints in full, complete with appendices, so that as an
appendix to this ruling, incl. the discussions in Scientific
American, they form part of the description of the case. The
same applies to Bjørn Lomborg's replies to the complaints. The
interested public will thus be granted an opportunity to have
full access to the facts of the case.
The whole of DCSD can endorse the Working Party's
description of the three complaints and of the problems
associated with the issue of whether Bjørn Lomborg's book
should even be evaluated on the basis of scientific criteria
and thus with determining the continued course of action in
its consideration of the case.
Nor during DCSD's discussion of the cases has there been
consensus as to whether the book "The Skeptical
Environmentalist" is a scientific work and should be assessed
in accordance with scientific standards. Some members do not
regard the book as science, but rather as a debate-generating
book. In this, they refer to the fact that, with the vast
breadth of topics treated and the lack of qualification of any
scientific method - including criteria for the selection of
sources - the book does not present the appearance of a
scientific work but precisely that of a provocative
debate-generating publication. Other members refer to the fact
that Bjørn Lomborg himself has opted to present himself as
Associate Professor of Statistics at the Department of Social
Sciences at the University of Aarhus and has given his book
scientific shape by virtue of the copious use of notes and
references. Adding to this that the book appears as a research
monograph in the University of Aarhus Yearbook for 2001 and is
widely perceived as being scientifically founded, these
members did not feel that DCSD could merely decline to deal
with the complaints.
Accordingly, by way of conclusion to this discussion, all
members of the three DCSD committees concur in the view that
DCSD should not simply decline to take a position on the
complaints.
Both in Denmark and abroad, in broad professional circles
and particularly from the pens of natural scientists, powerful
professional objections have emerged concerning the
correctness of the conclusions cited by Bjørn Lomborg. The
correctness of Bjørn Lomborg's conclusions is thus disputed,
inter alia by the researchers who have expressed their
opinions in Scientific American at the request of the editors
concerned.
However, it is not DCSD's remit to decide who is right in a
contentious professional issue, but merely whether a complaint
about scientific dishonesty is justified.
This task is laid down in Danish Executive Order No. 933 of
15 December 1998:
Section 2. The Danish Committees on Scientific
Dishonesty are mandated to consider cases of scientific
dishonesty lodged with the Committees in the form of a
complaint ..................
Section 3. Scientific dishonesty includes actions or
omissions in research which give rise to falsification or
distortion of the scientific message or gross
misrepresentation of a person's involvement in the research,
and includes:
- Fabrication and construction of data.
- Selective and surreptitious discarding of undesirable
results.
- Substitution with fictitious data.
- Deliberately misleading use of statistical methods.
- Deliberately distorted interpretation of results and
distortion of conclusions.
- Plagiarization of others' results or publications.
- Consciously distorted reproduction of others' results.
- Inappropriate credit as the author or authors.
- Applications containing incorrect
information.
Subs. 2. In order to label a conduct as scientific
dishonesty, it must be possible to document that the person in
question has acted deliberately or exercised gross negligence
in connection with the activities under
consideration.
Section 3, subs. 1 stipulates the objective fundamental
condition governing scientific dishonesty, namely that there
has been falsification or distortion of a scientific message,
enumerating a non-exhaustive list of examples of such actions.
Subs. 2 of the provision lays down the subjective requirements
that must always have been met for an action to be able to be
characterized as scientifically dishonest.
The thing which is special about scientific assertions is
the process implemented by scientists prior to presenting the
result. In simplified terms, the process consists of
formulating a hypothesis, an outline of a method which lends
itself to falsifying or proving the probability of the
correctness of the hypothesis, completing the investigation
described and publishing the result following a thorough
review process.
Those who conduct such scientific investigations are
usually researchers who already command an in-depth knowledge
of the specialist area within which the investigation is to be
done. Within the field of the health and life sciences,
especially, it is currently very common for research to be
conducted by several individuals jointly, so that together
they cover the different academic and specialist fields
involved.
One problem peculiar to all research is that of avoiding a
situation in which the prior advancement of a hypothesis by
the scientist results in that scientist, in his or her work on
the material under investigation, eliciting the very data and
facts capable of supporting the hypothesis and omitting to
admit those considerations and observations that fail to
support the hypothesis. If this is done intentionally or as a
result of gross negligence, the outcome is scientific
dishonesty. As DCSD's cases show, such a thing is very seldom
documented. On the other hand, in the scientific process there
is always reason to be highly alert to the potential risk of a
scientist admitting data to corroborate a hypothesis more
subconsciously than data militating against it. The fear of
such a bias is at the root, for example, of the widespread use
by the health sciences of double-blind studies, in which the
researcher him/herself is kept in the dark about the
desirability or undesirability of a result in relation to the
hypothesis in the particular instance at hand. However, a
research technique of this kind does call for particularly
randomized trial material normally unavailable in other
branches of science such as the social sciences.
With the volume of data present in this day and age in
virtually all fields, any research process will typically
involve the need to make a selection too. This, coupled with
the risk of bias just mentioned, makes it particularly
imperative to be aware of and describe the criteria on the
basis of which the underlying material has been chosen, and
for the researcher not to be blinkered in his or her
selection, but precisely to bear in mind that the scientific
process is based on a critical approach, in which the aim is
to investigate whether or not the hypothesis put forward can
be supported by data.
Moreover, it should be noted that there are quite specific
difficulties associated with the elaboration of cost-benefit
analyses aimed at serving to elucidate where the application
of resources provides best value for money. Such an analysis
consists of converting all goods into a financial amount. Such
conversion often reflects a particularly discretionary choice
on the part of the analyst.
In the context of the present case, DCSD has been sensitive
to the World Bank's World Development Report 2003:
"Sustainable Development in a Dynamic World" and the UN's
summary of the publication: "Providing Global Public Goods,
Managing Globalization", published in 2002. In the latter
publication, reference is made to an attempt to draw up a
cost-benefit analysis that illustrates the annual cost of
providing certain global public goods (including a reduction
in comprehensive illness burdens and climate change) as
compared with the cost of remaining passive. It is mentioned
that making such cost-benefit analyses requires considerable
effort and in-depth analyses of concept, measurement method
and data. Yet a provisional attempt at such an analysis
indicates that passivity is particularly costly and that the
cost of doing nothing exceeds the cost of any initiative
taken. This is mentioned only to highlight the caution that
needs to be exercised in connection with such cost-benefit
analyses.
As reproduced above under item 3, Scientific American has
asked leading experts to assess Bjørn Lomborg's treatment of
the fields in which they have special scientific insight.
DCSD did consider whether a better basis for evaluating the
cases under review would be obtained by itself forming ad hoc
committees with accredited experts in the respective fields. A
number of members voiced the view that sourcing new expert
evaluations might possibly create scope to establish whether
the defendant has not only-as the experts at Scientific
American claim-used selective data, but whether he has done so
wilfully in order to delude the public, and hence enable DCSD
to ascertain the presence or absence of the subjective
conditions required to uphold scientific dishonesty.
DCSD, however, has reached the conclusion that new experts
would scarcely be able to add new dimensions to the case. In
this process of deliberation, a crucial role has also been
played by the fact that even on the existing basis there is
agreement at DCSD in adjudging the defendant's conduct to be
contrary to good scientific practice, as expressed below.
8. DCSD's position
On the basis of the material adduced by the complainants,
and particularly the assessment in Scientific American, DCSD
deems it to have been adequately substantiated that the
defendant, who has himself insisted on presenting his
publication in scientific form and not allowing the book to
assume the appearance of a provocative debate-generating
paper, based on customary scientific standards and in light of
his systematic onesidedness in the choice of data and line of
argument, has clearly acted at variance with good scientific
practice.
Subject to the proviso that the book is to be evaluated as
science, there has been such perversion of the scientific
message in the form of systematically biased representation
that the objective criteria for upholding scientific
dishonesty-cf. Danish Order No. 533 of 15 December 1998-have
been met. In consideration of the extraordinarily wide-ranging
scientific topics dealt with by the defendant without having
any special scientific expertise, however, DCSD has not
found-or felt able to procure-sufficient grounds to deem that
the defendant has misled his readers deliberately or
with gross negligence.
In accordance herewith and subject to the proviso that the
book under review is to be evaluated as science, DCSD has
arrived at the following
Ruling:
Objectively speaking, the publication of the
work under consideration is deemed to fall within the concept
of scientific dishonesty.
In view of the subjective requirements made in
terms of intent or gross negligence, however, Bjørn Lomborg's
publication cannot fall within the bounds of this
characterization. Conversely, the publication is deemed
clearly contrary to the standards of good scientific
practice.
For and on behalf of the Committees

Chairman of DCSD
