Pandora's Box the Dangers of Politically Corrupted Science for Democratic Public Policy
BY JOHN C. LUIK
The Context
THE ASSUMPTIONS ABOUT THE NATURE OF persons and of the legitimate
role of the State (of necessity unargued for) which structure
our argument are those of an unreconstructed liberal individualist,
namely, that the individuals who make of democratic society are
the best judges of the shape they wish their lives to take, and
consequently they should be accorded the maximum liberty, compatible
with similar liberty for everyone else, to think, believe, and
live as they choose. This means that the State's role is at least
fourfold: first, to prevent or minimize harms by one individual
to another individual; second, to minimize and where necessary
adjudicate the inevitable conflicts that occur between individuals
and between individuals and the community; third, to defer, wherever
possible, from moral judgments about how its citizens choose to
shape their lives; and finally, to create the minimal institutional
conditions which allow its citizens' self-chosen lives the best
chance of fulfillment.
What this means is that the State will resist the impulse, however
well-intentioned, to undermine and intrude upon its citizens'
capacities and inclinations for autonomy by defining one vast
and unassailable conception of the good live to which all must
subscribe. What this means is that the State will see its citizens
as persons of intrinsic worth, fully equivalent in moral standing
with itself, with lives not to be managed or saved, but to be
allowed to develop in ways of their own choosing.
In order to understand the ways in which science and public policy
intersect in the debate over smoking - as indeed over may other
"health" issues - it is necessary to place the smoking
controversy in general and the Environmental Tobacco Smoke controversy
in particular within the larger context of both governmental and
non government efforts to discourage tobacco use. For most of
the twentieth century the campaign to delegitimize smoking as
employed two major weapons, science, particularly epidemiology,
and morality, within the general conceptual framework of what
can be called health paternalism. Though the mix has varied,
the conjunction of the two has been not only consistent, but also
highly effective.
For example, once it was established that smoking increased the
risks of ill health in smokers, the groundwork was laid for a
series of moral arguments that purported to show that subjecting
oneself to these risks was both so irrational and immoral as to
justify government efforts to prevent one from assuming the risks.
The health paternalism at work here rests on a series of assumptions
about reason, autonomy, and the nature of persons that include
the following:
- autonomy is not the foundational democratic value inasmuch
as considerations of happiness and welfare frequently take
precedence over it;
- individuals are frequently irrational in that they
a. often do not understand their interests; and
b. even if they do understand their interests they do
not know how best to realize those interests;
- individuals need the State's help in
a. discovering and realizing their "true" interests; and
b. avoiding irrational courses of action that result
in unhappy consequences.
What unites these assumptions is the belief that the State is
justified in protecting competent adults from the allegedly harmful
consequences of their actions through restricting their autonomy.
Based on these assumptions, health paternalism advances the following
claims:
- health is the preeminent value which outweighs, in
most instances, all other values such that a rational person
would not normally place his health at risk in the interests
of some other value;
- there is but only healthy/rational way to live one's
life and such a way does not include activities that carry
with them significant risks to well-being or longevity;
- individuals have a moral obligation to order their
lives in this healthy/rational way; and
- the State is justified, indeed the State has a moral
obligation, to insure that its citizens conform to this health/rational
paradigm, even if they wish not to or are unable to through
their own efforts.
Health paternalism is thus a subtle shift away from the generally
uncontroversial right of the State to ensure that consumers are
fully informed about the risks of certain products or activities
to their health to the highly contentious claim that the State
is justified in attempting to manipulate and coerce. Despite
its highly problematic character, health paternalism has been
to some degree immune from the sorts of objections that are routinely
brought against other forms of paternalism. Health paternalism's
immunity from such criticism does not derive from the cogency
of its arguments but from the fact that it rests not just on moral
argument but on "unquestionable" scientific fact. And
in a world in which science is increasingly the source of both
truth and value the scientific character of health paternalism
is decisive.
But, however closely aligned to science, the ability of health
paternalism to secure all of the public-policy objections of the
anti-smoking movement was always constrained by the fact that,
at least within democratic societies, the justifications for government
intervention to protect adults from themselves - to coerce "healthy"
lifestyles - would continue to have a totalitarian flavor about
them that would ensure significant and widespread opposition.
It is only by demonstrating the dangers from smoking transcend
the smoker and extend to innocent bystanders that the anti-smoking
movement could move beyond obvious health paternalism and enlist
unambiguous support for public-policy measures designed to restrict,
ban, and criminalize public smoking. The movement away from the
risks of smoking for smokers to the alleged dangers of secondhand
smoke from nonsmokers does not mean that the health-paternalist
arguments have suddenly disappeared from the public-policy agenda
of the anti-smoking movement. Whether one is considering the
policy implications of tobacco advertising or the supposedly addictive
properties of nicotine, the paternalist justifications for government
interventions in the lives of smokers still constitute a significant
strand of the anti-smoking argument. What has changed is that
arguments about harms to self have assumed a secondary place to
arguments about harms to others. What has remained the same is
the fact that the new arguments about harms to others, to innocent
bystander, strongly resemble the old "paternalist" (often
religious) arguments. what is new is the consideration of science
and morality to justify public policy.
We wish to argue that:
- the "science" supporting the claims about
tobacco's risks to non-smokers is corrupted science, science
that has been politically laundered, science that because of
its corrupted status actually ceases to be science;
- the use of such science by the government and the anti-smoking
movement reveals not only the illegitimacy of their public-policy
agenda but the flawed character of the advocacy as well; and
- the existence and use of such corrupted science poses
a significant threat to legitimate democratic public policy.
CORRUPTED SCIENCE
If the government and the anti-smoking lobby are to justify their
claim that the debate in society about smoking in the last decade
of the twentieth century is really a debate about the dangers
that smoking poses to nonsmokers then it is imperative that those
dangers be demonstrable, compelling, unequivocal, and significant.
And it is only science that can deliver dangers with the requisite
pedigree. Should the scientific evidence be less than decisive,
the debate about smoking will return to a debate about the legitimacy
of health paternalism, which is a debate that neither the government
nor the anti-smoking movement can easily win. Everything, therefore,
depends on science. And with so much at stake, the pressure to
adjust, shave, create, ignore, reevaluate, even manipulate, is
enormous.
The pressure comes from a least four sources: from the dispositions
of scientists themselves, from the rational character of science
itself, from the structure of the scientific enterprise, and from
society's expectations of science.
- Scientists, like everyone else, have their own personal perspective,
values, and ideological agenda, whatever their commitment as scientists
to the objective nature of science. Indeed, a good many scientist,
either apart from their scientific training or because of it,
believe that tobacco use is dangerous and immoral. Most scientists
and most healthcare professionals have come of age in a professional
atmosphere
PAGE 2
that for the last twenty-five years has been increasingly hostile
to tobacco use. It is not unreasonable to assume that may scientists
have a strong professional interest in establishing their personal
beliefs and the beliefs of their milieu as scientific fact. As
William Broad and Nicholas Wade observe in Betrayers of Truth:
Fraud and Deceit in Science, "science is not a perfectly
objective process. Dogma and prejudice, when suitably garbed,
creep into science just as easily as into any other human enterprise,
and maybe more easily since their entry is unexpected."
- The ideology of science, which focuses almost exclusively
on the objective and rational character of science, tends to blind
both scientists and those who rely on science to the fact that
there are other elements involved in science besides strict logic
and rationality. "The presence of a strong rational element
in science has been taken to mean that that is the only significant
element of scientific thought. But creativity, imagination, intuition,
persistence, and many other nonrational elements are also essential
parts of the scientific process, and other less vital qualities
such as ambition, envy and the propensity to deception also play
a role" (Broad and Wade, p. 218). These other aspects of
the scientific process, which are common to other areas of creative
endeavor, tend to work against objectivity, particularly when
they are not acknowledged as part of the scientific paradigm.
- Scientific careers are advanced on the basis of published,
peer-reviewed findings findings that for the most part grow out
of funded research. The decisions about which research project
to pursue and which research results to publish are often determined
by a subtle interplay between scientific orthodoxy, funding procedures
quite genuine career considerations, and the search for scientific
truth.
- Science exists within a society that has certain expectations
about what science ought to do, one of which is that science exists
to make the case, as it were, against whatever it is that society
considers to be dangerous. The fact that much of society believes
tobacco to be dangerous creates a strong series of incentives
to establish and indeed enlarge the range of smoking-induced harms,
while at the same time ignoring or suppressing research that questions
these received orthodoxies.
But what, it might be asked, is corrupted science? And more
importantly, what is the evidence that the official Environmental
Tobacco Smoke (better known as ETA or "passive smoke")
story is indeed an instance of such a corrupted science? Could
it not be the story is indeed an instance of such science? Could
it not be the case, for instance, that the Environmental Protection
Agency's conclusions about ETS are in fact simply incompetent
science, science that has failed to do its work properly but not
science that has deliberately decided to tell the wrong story?
It is certainly true that not every instance of weak or flawed
science is an instance of corrupted science. Corrupted science
has at least three characteristics that mark it off from simply
incompetent science.
First, corrupt science is science that moves not from
hypothesis and data to conclusion but from mandated or acceptable
conclusion back to selected data in order to reach the mandated
or acceptable conclusion. That is to say, it is science that
uses selected data to reach the "right" conclusion,
a conclusion that by the very nature of the data necessarily misrepresents
reality.
Second, corrupt science is science that misrepresents
not just reality, but its own process in arriving at its conclusions.
Rather than acknowledging the selectivity of its process and
the official necessity of demonstrating the right conclusion,
and rather than admitting the complexity of the issue and the
limits of its evidence, it invests both process and its conclusions
with a mantle on indubitability.
Third, and perhaps most important, whereas, normal science
deals with dissent on the basis of the quality of its evidence
and argument and considers ad hominem argument as
inappropriate in science, corrupt science seeks to create formidable
institutional barriers to dissent through excluding dissenters
from the process of review and contriving to silence dissent not
by challenging its quality but by questioning its character and
motivation.
In effect the, corrupt science is science that is flawed in both
its substance and its process and that seeks to conceal these
essential flaws. It is essentially science that wishes to claim
the policy advantages of genuine science with doing the work of
real science.
The evidence that the EPA's science on ETS is corrupt science
falls into two categories: evidence about the substance of the
science and evidence about the process involved in creating and
using the science.
THE SUBSTANTIVE ISSUE
The EPA's report Respiratory Health Effects of Passive
Smoking: Lung cancer and Other Disorders claims that "based
on the weight of the available scientific evidence, the U.S. Environmental
Protection Agency has concluded that the widespread exposure to
environmental tobacco smoke in the United States presents a serious
and substantial public health impact." The hedging is in
the swerve from "hazard" to "impact." Is
this the case?
In order to answer this question one must first know something
about the data on which the EPA's decision is based. The EPA's
report refers to the thirty epidemiologic studies on spousal smoking
and lung cancer that have been published between 1982 and 1990.
It is important to note that in referring to the report then
EPA administrator William
PAGE 3
Reilly spoke about ETS in the workplace and, though the Report
has been used as a basis for demanding smoking bans both in public
places and in workplaces, the EPA did not examine those studies
that look at workplace ETS exposure. The overwhelming majority
of these do not find a statistically significant association between
exposure to ETS and lung cancer in nonsmokers: a fact that by
itself destroys the legitimacy of any harm based demand for public
or workplace smoking bans.
Thus, to begin with, the EPA's case is based not on workplace
or public-place ETS exposure , but on the risks of non-smokingspouses contracting lung cancer from their smoking spouse. But
what of the thirty studies? The thirty studies come from different
countries and vary substantially in size. Some studied fewer
than twenty subjects, others are based on larger populations,
with the largest study involving 189 cancers cases. Of the thirty
studies, twenty-four reported no statistically significant association;
only six reported a statistically significant t association, this
is, a statistically significant increased risk for those nonsmoking
spouses. Relative risks are further classified into strong risks
or weak risks depending on the magnitude of the risk ratio. Within
the thirty studies on ETS and lung cancer none reported
a strong relative risk. Moreover, whenever the assessment of
relative risk is weak, there is a substantial possibility that
the finding, the assessment, is artificial rather than real.
That is to say, there is a strong likelihood that even the weak
relative risk is a reflection not of some real-world risk, but
of problems with confounding variables or interpretative bias.
There are, for instance, at least twenty confounding factors
ranging from nutrition to socioeconomic status that have been
identified as associated with the development of lung cancer.
Yet none of the thirty studies attempts to control for all of
these factors. So in assessing the global scientific evidence
about ETS and lung cancer, the crucial conclusion is that none
of the studies report a strong relative risk for nonsmokers married
to smokers.
The EPA Report discusses all thirty studies but limits its statistical
analysis to only eleven U.S. studies of spouses of smokers. Of
the eleven studies, the EPA claims that ten reported no statistically
significant association between ETS exposure and lung cancer,
and only one reported a statistically significant association.
But this claim about the one U.S. study is in fact true only
by using the EPA's unique 90 percent confidence level. Using
the accepted 95 percent confidence level none of the eleven
studies reported a statistically significant risk.
The EPA analysis of these eleven studies claims that together
they show a statistically significant t difference in the number
of lung cancers occurring in the nonsmoking spouses of smokers,
such that they suffer 119 such cancers compared with 100 such
cancers in nonsmoking spouse of nonsmokers. It is this finding
of statistical significance, a finding based on only eleven U.S.
studies, none of which demonstrate a statistically significant
increased risk unless they are "reanalyzed" using the
EPA's 90 percent confidence interval (and even such "coaxing:
of the figures could produce only one study that purported to
show statistically significant increased risk), that provides
the only basis for the EPA's decision to classify ETS as a "Group
A" carcinogen.
In order to arrive at its "conclusion," the EPA pooled
the data from the eleven studies into a combined data assessment
called a meta-analysis. Meta-analysis is governed by its own
rules: not every study is a candidate for such combined analysis.
In general, meta-analysis is appropriate only when the studies
being analyzed together have the same structure. The difficulty
with the EPA's use of meta-analysis of the eleven ETS studies
is that it has failed to provide the requisite information about
the structure of those studies, information crucial for an independent
assessment of whether the studies are indeed candidates for meta-analysis.
Thus, the EPA conclusion is based on a meta-analysis that is
difficult, if not impossible, to verify.
Adjusted confidence levels are not, however, the only problem
with the EPA analysis. Equally disturbing is the EPA's use of
a one-tailed test as opposed to a two-tailed test. Two-tailed
tests (see sidebar) are generally used in statistical analysis
because it is rare for one to know a priori that a null
hypothesis can be discredited in only one direction. By using
a one-tailed test the EPA assumes that ETS exposure can only increase
the lung cancer risk, despite the fact that a substantial number
of studies show a decreased risk. (One recent large study
even showed a statistically significant decreased risk.) While
the EPA claims that a one-tailed analysis actually compensates
for a 90 percent confidence interval, what the use of such an
analysis actually does is reduce the confidence level even further.
PAGE 4
The quality of the EPA's ETS science is the issue of "confidence
intervals." Even by limiting its analysis to only eleven
studies, and even by lumping these studies together through a
meta-analysis, the EPA could not have achieved the "right"
result if it had not engaged in a creative use of what epidemiologists
call confidence intervals. Essentially, confidence intervals
express the likelihood that a reported association could have
occurred by chance. The generally accepted confidence interval
is 95 percent, which means that there is a 95 percent confidence
that the association did not occur by chance. Inasmuch as most
epidemiologists use the 95 percent confidence interval, the EPA
itself, until the ETS report, always used this interval. Curiously,
the EPA decided that in this instance it would use a 90 percent
confidence interval, something that effectively doubles the chance
of being wrong. Even more curious is the fact that when asked
to justify this departure from accepted scientific procedure,
EPA administrator Reilly simply replied that the 90 percent confidence
interval "was recommended to us by the scientific community
as appropriate to this data." What Mr. Reilly really means
by "appropriate to this data" is that without using
this 90 percent standard, the EPA could not have found that the
eleven U.S. studies were "statistically significant."
Without employing a novel standard, without in effect changing
the accepted rules of epidemiological reporting, the EPA result,
already painfully coaxed into existence, would not have existed,
and ETS could not have been labeled a "Group A" carcinogen.
Thus, despite all of its careful selection of the right data,
its meta-analysis and finally its relaxed confidence intervals,
the conclusive points remains, as Huber, Brockie, and Mahajan
notes in Consumers Research in the United States (1991),
that "no matter how the data from all of the epidemiological
studies are manipulated, recalculated, 'cooked,' or 'massaged,'
the risk from exposure to spousal smoking and lung cancer remains
weak.... No matter how these data are analyzed, no one has reported
a strong risk relationship for exposure to spousal smoking and
lung cancer."
THE PROCESS ISSUE
While a careful look at the substance of the EPA's ETS claims
clearly shows why this science can be called nothing less than
corrupt science, an examination of the process underlying this
science demonstrates even more clearly its wholly corrupted character.
There are at least ten specific process issues worth noting,
each of which highlights a slightly different dimension of the
corrupted character of the EPA's ETS science.
- First, EPA science issues from a perspective that can
be traced back to the Lalonde Doctrine propounded by former Canadian
Minister of National Health and Welfare, Marc Lalonde. Lalonde
argued that health messages must be vigorously promoted even if
the scientific evidence was incomplete, ambiguous, and divided.
Health messages must be "loud, clear and unequivocal"
even if the evidence did not support
PAGE 5
such clarity and definition. What we have in the EPA is simply
the Lalonde Doctrine as an institutionalized process. Clearly
the substance of the ETS data does not support its "Group
A" status, nor does it support public and workplace smoking
bans (desirable as some might find them on other grounds) on the
grounds that ETS threatens the health of nonsmokers.
But the substance of the ETS data is to be ignored because the
Lalonde Doctrine requires that the substance be portrayed as something
that it is not in order to further the health agenda.
What this does is to build into the heart of the scientific enterprise
an institutionalized motivation and justification for allowing
ends extrinsic to science to determine the findings of science,
for allowing science to be subject to an agenda not its own, for
allowing science to lie with a clear conscience. Once one has
come to see science as something that of necessity happens within
the context of health promotion, then the process corruptions
of the EPA follow quite "naturally."
This explains why at one level those involved with the EPA decision
on ETS are quite frank about the process. For instance, the EPA
official responsible for the revised ETS risk assessment was quoted
in Science (July 31, 1992) as admitting that "she
and her colleagues engaged in some fancy statistical footwork"
to come up with an "indictment" of ETS. (The footwork
to which she refers is the novel 90 percent confidence interval
and the one-tailed test.) Or to take another process example,
the Science Advisory Board which reviewed the initial draft risk
assessment on ETS, and found the case against ETS based on its
association with lung cancer unconvincing, actually urged the
EPA staff to attempt to "make the case" against ETS
on the basis of the similarities between ETS and mainstream smoke.
To be fair, the consequences of the Lalonde Doctrine are not
confined to the EPA's anti-smoking agenda. For instance, an article
in the Journal of the American Medical Association for
July 29, 1989, reported a study that claimed to show a link between
ETS exposure and an increased risk of cervical cancer. In response
to critics who noted that such a link was biologically implausible
and that the study had ignored confounding factors, the authors
replied that the study was justified simply on the ground that
it might reinforce the "dangers of smoking" message.
"While we do not know of a biologic mechanism for either
active...smoking or ETS to be related to cervical cancer, we do
know that cigarette smoking is harmful to health. The message
to the public, as a result of this study, is one that reinforces
the message that smoking is detrimental to health." It would
be difficult to find a more succinct example of the Lalonde Doctrine
at work. There is no compelling evidence to support our claim,
the authors all but admit, but it is import, in the interests
of health promotion, that the public be made to think that there
is scientific evidence of harm.
- But second, while those involved in the EPA process
are at one level open about the process, at another level they
are profoundly dissembling. For instance, the EPA fails to mention
that the "Group A" status for ETS was arrived at using
a process that violates its own Guidelines for Carcinogenic Risk
Assessment. Rather than acknowledging that this suggested
that both the substance of its findings and the process were corrupt,
the Science Advisory Board reviewing the ETS issue argued that
this suggested a need: not that ETS posed no threat to the health
of nonsmokers, but rather that the Guidelines for Carcinogenic
Risk Assessment be changed. Given that the right conclusion must
be reached, and the data do not support that conclusion, one must
manipulate the data and revise the guidelines governing the process
and the conclusion.
- Third, the ETS risk assessment process has been corrupted
from the outset by the fact that it has repeatedly violated the
standards of objectivity that prevail in legitimate science by
utilizing individuals with anti-smoking biases. One member of
the group working on the ETS issue at the EPA is an active member
of U.S. anti-smoking organizations, while the Science Advisory
Board that examined the EPA's ETS work included not only a leading
anti-smoking activists, but several others strongly opposed to
tobacco use. Finally, the EPA contracted some of the work on
certain documents related to the ETS risk assessment to one of
the founders of a leading anti-smoking group.
- Fourth, the EPA changed the accepted scientific standard
with respect to confidence intervals, without offering any compelling
justification, on order to make its substantive findings statistically
significant.
- Fifth, the EPA's Workplace Policy Guide which as a
policy document would, in the course of normal scientific process,
be developed only after the scientific evidence was in, was actually
written before the scientific risk assessment was even completed,
let alone reviewed and finalized. Quite obviously, science was
to be made to fit with policy, rather than policy with science.
- Sixth, the EPA fails to note that, if the two most
recent U.S. ETS studies were to be included along with its eleven
other studies, it would have resulted in a risk assessment that
was not statistically significant, even using the 90 percent confidence
interval. With its entire "conclusion" at risk, there
are exceedingly compelling process reasons for the EPA to have
excluded these two later studies from their analysis.
- Seventh, exclusion, however, was apparently insufficient,
for the EPA does more than simply not use the studies, it actually
refers to them in an appendix and misrepresents one of them by
claiming that it supports the EPA's ETS conclusions. The study,
by Brownson, et. al, which appeared in the November, 1992 American
Journal of Public Health, reported no statistically
significant increase in risk between lung cancer and ETS exposure.
In order to get around this politically unacceptable conclusion,
the EPA quotes Brownson as concluding: "Ours and other recent
studies suggest a small by consistent increased risk of lung cancer
from passive smoking." But this is not the issue, as the
EPA well knows. The questions is not whether there is a small
increased risk, but whether there is a statistically significant
risk, which Brownson concludes there is not. In effect, the EPA
misrepresents a scientific finding by changing their terms of
reference from statistical significance to just plain risk.
This penchant for misrepresentation is not, however, confined
to recent studies. For instance, the EPA analysis consistently
makes reference to the Garfinkel, et. al. study. At Chapter 5.48
the EPA claims that the Garfinkel study presents "at least
suggestive evidence of an association between ETS and lung cancer...."
But a careful reading of Garfinkel does not confirm this at all.
Garfinkel actually says that "we found an elevated risk
of lung cancer, ranging from 13-31 percent, in women exposed to
smoke of others, although the increase was not statistically significant."
(L. Garfinkel at al, "involuntary Smoking and Lung Cancer:
A case-Control Study," Journal of the National Cancer
Institute, 75, 1985.) The entire questions of suggestive
evidence is bogus: the relevant questions is whether Garfinkel
found a risk that was statistically significant. He did not,
and the EPA misrepresents his findings.
- Eighth, the EPA represents it process as a comprehensive
and objective analysis of the ETS data. In the usual course of
things this would imply a careful examination of the criticisms
that have be leveled at the studies used to reach its conclusions,
However, a careful examination of the bibliography accompanying
the report suggests that this is not the case. Although the note
with the bibliography indicates that it is not a "comprehensive
list of all references available on the topic," it is still
a list of all references cited and reviewed for the report. Yet,
to take but one example, one would never know from the report
or its bibliography that the work of Trichopoulous had been subjected
to significant criticism by both Burch and Heller, since neither
is mentioned in the bibliography. Nor would one know that Trichopoulous
acknowledged such criticism and even criticized his study himself.
(See Trichopoulous et. al, "Lung Cancer and Passive Smoking"
Int. J. Cancer, 27:1-4.)
Now the possible explanations for such selectivity are that:
1. The authors of the study are not familiar with such criticisms,
which would suggest incompetence, or
2. They are familiar with the criticisms but have misunderstood,
ignored, or discounted them.
But even if one were to discount or ignore them, it is still
odd, if one is committed to objectivity and openness, not to cite
them. Not to cite them suggests that one wishes to act as if
they didn't exist, and to do this is to give rise to more than
the suspicion that the EPA's ETS work is really an instance of
a closed-loop process abuse. In a closed loop the circle is never
opened up to divergent, dissenting views that challenge the orthodox
conclusion. It is not simply that such divergent views are discounted,
it is rather that, as the EPA discussion and bibliography indicate,
they simply are never heard - indeed judging from the bibliography
they don't exist. When one considers this closed loop process
in the context not merely of what the EPA excluded in terms of
dissenting voices, but in the context of what it sought to include
in terms of determining voices - the anti-smoking movement - then
it is hard to assign any degree of objectivity to the process.
- Ninth, there is significant evidence that the EPA ignored
the misgivings of its own scientists about it ETS assessment process
and conclusion. Two internal EPA documents (April 27, 1990, and
March 23, 1992) both by the EPA's Environmental Criteria and Assessment
Office and both recently released by Congressman Tim Valentine,
suggest that the EPA process and report was badly conceived and
argued, that the alleged "causal" connection between
lung cancer and ETS was overstated, and that the evidence does
not support a Group A carcinogen classification of ETS.
PAGE 6
- Tenth, despite the significant difficulties that
have been raised about the quality of EPA science, the EPA process
is incapable of correcting itself. This was made particularly
clear by the Expert Panel in its report Safeguarding the Future:
Credible science, Credible Decisions, which noted that:
1. EPA "science is of uneven quality";
2. the "EPA has not clearly conveyed to those outside
or even inside the Agency its desire and commitment to make high-quality
science a priority";
3. "the science advice function - that is the process
of ensuring that policy decisions are informed by clear understanding
of relevant science - is not well defined or coherently organized
with EPA";
4. the "agency does not have a uniform process to
ensure a minimum level of quality assurance and peer review for
all the science developed in support of Agency decision making";
5. the "Agency lacks the critical mass of externally
recognized scientists needed to make EPA science generally credible
to the wider scientific community";
6. "science should never be adjusted to fit policy."
This is perhaps the most significant process corruption of all,
namely, a process that is quite conscious of its problems but
is unwilling and unable to address them. Of course even this
characterization is perhaps too kind given that what the Expert
Panel describes as problems are really, for the anti-smoking movement,
just the normal way that science must proceed if it is to make
the anti-smoking case. If this the case, then there is no conscious
sense of process problems. What the Expert Panel's Report actually
provides, of course, is another description of corrupted science
- science corrupted in its substance and its process; science
driven by a predetermined policy agenda; science based on inadequate
data; science of uneven quality and inadequately peer-reviewed;
science lacking critical validation by outside scientists representative
of "wider scientific community;" and science, finally,
fully aware of its corruption, but unable to heal itself.
THE USES OF CORRUPTED SCIENCE
It is clear from the way in which the EPA has handled the ETS
issue that the anti-smoking movement is aware of, if not directly
involved in, using corrupted science in the pursuit of its public-policy
agenda. Indeed, as Alvan Feinstein, a Yale University epidemiologist
writing in Toxicological Pathology noted, a prominent epidemiologist
commenting on the EPA's work on ETS admitted that, "Yes,
it's rotten science, but it's in a worthy cause. It will help
us to get rid of cigarettes to become a smoke-free society."
But what sorts of moral questions are raised by the anti-smoking
movement, a movement that has always claimed the moral high ground
for itself alone, using and pressuring governments to use corrupted
science as a basis for public policy?
One moral questions is obviously the questions of the legitimacy
of misrepresentation, for corrupted science is a bottom science
that misrepresents the state of reality. and what a careful analysis
of the scientific claims of the EPA and the anti-smoking movement
reveal is a profound and systematic disregard for the truth about
the dangers from ETS. Not only are data manipulated to produce
the desired results and suppressed or dismissed when they do not
fit the standards of political correctness, but accepted standards
about confidence intervals are changed without justification.
In effect, one has an ethic that legitimizes misrepresentation
in the service of a good cause - "a smoke-free society."
But is a smoke-free society a sufficient justification for a
public health movement founded on unreliable science and blatant
misrepresentation? We would suggest that it isn't. First structuring
a public health campaign on deceit is to place it upon terrain
that is both notoriously slippery and crevice-laden. The frightening
thing about institutionalized deceit, even in the allegedly righteous
cause of eliminating smoking, is that like any moral corrosive
it is both so easy to justify and so difficult to restrict its
use to the ends that originally justified its employment. Second,
the entire project of corrupted science, like all projects of
deception, is designed to manipulate individuals and society to
do things that they would not normally do, and to do so based
on a false picture of reality. The liar's game, is after all,
morally deviant precisely because it subverts our autonomy by
misinforming us. the liar distorts the truth in order to obtain
our consent not through argument but through coercion. And the
great enemy of freedom is not so much overt coercion but the coercion
brought about by biased information. The corruption of a science
that misrepresents is moral corruption of the most foundational
sense, for it corrupts a centerpiece of both morality and democracy,
namely our ability to act freely.
But there is a second moral question here that goes beyond the
morality of misrepresentation into what might be called the morality
of suppressing dissent. Both the process of producing corrupted
science and of utilizing it as the basis for public policy demand
a fundamental intolerance of dissent, both scientific and otherwise.
The imperatives of health promotion are such that both the ambiguities
and uncertainties that form a legitimate part of science and more
importantly, serious questions about the quality of the evidence
and whether it justifies the proposed public-policy measures,
cannot be tolerated. This means that scientific and public-policy
dissent must be suppressed by portraying dissenters as in the
pay of the tobacco industry or marginal to the scientific establishment.
This strategy raises a host of subsidiary moral questions. Whatever
the cost, "science" must be seen to provide a conclusive
and united answer to the question of tobacco and its harms to
the innocent. Thus, despite the vital role of questions, argument,
and dissent in science as well
PAGE 7
as in democratic life, the anti-smoking movement seeks to silence
dissent in the interests of protecting not the truth but its misrepresentation
of the truth.
The third moral question centers on what the manufacture and
use of such science does both to science and to legitimate democratic
public policy. Corrupted science is rather like an intellectual
acid rain that eats away at everything that it touches. For instance,
it gnaws away at the distinguishing characteristic of science
- its objectivity - and threatens to render science essentially
worthless for public-policy purposes. Though science is never
completely objective, if indeed complete objectivity is possible,
it at lease, in distinction from much of the political process,
professes a fundamental interest in reason, evidence, and bias-free
judgment. In fact, much of science's standing in contemporary
society derives from its objective character, as does much of
its usefulness in the public-policy process.
In effect, we have a high degree of confidence in the scientific
process as providing a careful, evidenced, and to some degree,
value-free, assessment of certain questions relating to public
policy, and it is precisely this utility that the use of corrupted
science threatens. If science ceases to work outside of the political
and policy process, if it ceases to be a tool available to all
sides of an issue, if it becomes politicized and ideologically
sensitive, then it ceases to be valuable in the policy process.
Rather than acting on the voice of reason, it becomes nothing
more than another special pleading.
In this sense, to use corrupted science, for however allegedly
worthy an end, is inevitable and irretrievable to corrupt science
itself. No one who genuinely cares about good public policy,
policy crafted on the basis of careful argument, cogent reasoning,
and compelling data, policy that can stand the test of careful
probing and consistent dissent, can countenance the corruption
of science.
But the use of bogus ETS science to manipulate the public-policy
debate on smoking threatens not just science, but also the standards
of rationality that distinguish legitimate public policy. Adherence
to the norms of rationality require that the identification of
problems, causes, and solutions be based on empirical evidence
of the most rigorous sort, evidence that is specific, strong,
consistent, or coherent and demonstrates the appropriate causal
connections, that rest on rational arguments which are clear and
logically compelling. Problems and solutions that cannot meet
this standard of argument are not allowed a place in the public-policy
process since to do so is to abandon the commitment to reason
that is a fundamental democratic value.
Yet the use of corrupted ETS science as a basis of public policy
is nothing less than an abandonment of rationality as a measure
of legitimate public policy. As we noted above, the EPA and the
anti-smoking movement's ETS science cannot meet any of the tests
of rationality that determine legitimate public policy problems
and solutions. the ETS "evidence" is not specific,
strong, consistent, coherent, nor does it demonstrate the appropriate
causal connections. If it fails these tests, it cannot provide
compelling rational reasons - as opposed to rhetorical and emotional
reasons - for its public-policy recommendations.
The use of corrupted ETS science is, however, more than simply
an abandonment of reason in the public policy process; it is also
frightening, an attempt to institutionalize a particular irrational
view of the world as the only legitimate perceptive: to replace
rationality with dogma as the legitimate basis of public policy.
If the use of corrupted ETS science by the EPA and the anti-smoking
movement represented simply the abandonment of reason, then such
actions, would be simply nonrational. But the EPA's efforts go
beyond the nonrational to the irrational, to an assault on reason
itself. By refusing to include evidence of scientific dissent
from the officially determined "truth" about ETS, as
evidenced in the omission from key bibliographies of any references
to criticisms of key findings and studies, by manipulating and
mis-reporting data, and by portraying those who disagree as being
"mouthpieces: for the tobacco industry, the proponents of
the anti-smoking policy agenda reveal themselves as enemies of
the open and self-correction process of reason. In a very real
sense the "truth" about ETS ceases to be open to rational
assessment and assumes instead the status of revealed dogma.
And only those who ultimately fear, if not loathe, reason are
comfortable with dogma as the basis of public policy.
By far the most morally objectionable aspect of the anti-smoking
movement's use of the ETS issue is its readiness to use corrupted
science to deprive smokers not only of their right to pursue their
pleasure in public, but quite possible to gain or retain their
employment, or advance their prospects. Put more bluntly, it
is the question of whether it is morally justifiable to use bad
science to hurt people? What should never be lost sight of in
this debate is that without the alleged scientific justification
of harm to innocent parties, there is no compelling public-policy
rational for banning or restricting smoking in public places or
workplaces. Once the corrupted science is stripped away, there
simply are no harms, and without
PAGE 8
those harms, smoking becomes a self-regarding behavior, interventions
against which can only be advanced on patently paternalistic grounds.
The anti-smoking movement might still argue that public and workplace
smoking should be banned in order to discourage smokers from smoking,
but this argument loses its compelling harm-to-others' character
and becomes instead nothing more than an argument about the state
intervening in the private lives of competent adults.
What is so morally offensive here is that truly morally blameless
people - not the alleged victims of smokers - but smokers themselves,
are to be harmed in significant ways on the basis of bogus science
and for no good reason. What makes the morality of the anti-smoking
movement as corrupt as its science is that it is prepared to exploit
for its own ends our readiness to deprive individuals of certain
rights if the exercise of those rights appears to harm others
by explicitly manufacturing harms to others. In doing so, the
anti-smoking movement simultaneously violates perhaps the two
most fundamental moral principles, first by treating persons,
in this case smokers and their alleged harms to others, as merely
means to the end of a smoke-free society and not as ends in their
own right, and second by inflicting substantial pain on an entire
class of people without their consent and for no compelling reason.
But the question of the moral justifiability of using corrupted
science to hurt people goes beyond the question of depriving individuals
of their right to a significant pleasure, or even a job, to something
far more crucial, namely the justifiability of depriving individuals
of their moral standing through stigmatizing them as moral outcasts.
In the end, this is, of course, the logical outcome of ETS science,
to make smokers a class of moral miscreants who see themselves
and are seen by others as so ruthlessly intent on pursuing their
own interests that they are blind to the harm they inflict on
others. It is indeed but a short way from the claim, "Smoking
kills" to the conclusion that "Smokers kill."
But then, such a conclusion is the public-policy justification
for bans on public smoking.
The debate about Environmental Tobacco Smoke, though ostensibly
a debate about smoking, is really a debate about much more than
smoking. It is a debate at bottom about the legitimacy of perverting
science and public policy founded on science in the interests
of a particular health ideology. It is a debate a bottom about
the worth of a health paternalism that guarantees to leave all
of substantially less free but not less ill.
