A HISTORICAL VIEW OF SOCIAL RESPONSIBILITY IN GENETICS
Title: “A Historical View of Social Responsibility in Genetics.
Author(s): Beckwith, Jon
Source: Bioscience; May93, Vol. 43 Issue 5, p327, 7p
In the fictional Jurassic Park (Crichton
1991), mischievous genetic engineers let
loose breeds of dinosaurs that might
wreak havoc on the world. Partly
through the efforts of other scientists,
the damage is limited to a small region
of the globe and eventually the animals
are eliminated. The image of the
scientist who carries out ill-considered
experiments, often with claims for
benefits to humanity, is one of the most
common representations of scientists in
film and fiction.
Less common is the image of the socially
responsible scientist who takes action to
prevent damaging results of scientific
discoveries. However, particularly since
the development of atomic weapons, a
thin but fragile undercurrent has been
running through the scientific
community arguing that scientists must
take responsibility for the social
consequences of scientific research,
whether their own or others'.
Scientists were among the most vocal
spokespersons asking for bans or
restrictions on nuclear weapons in the
1950s and 1960s. In the 1970s, a group
of molecular biologists called
successfully for a moratorium on
recombinant DNA research until the
potential health hazards were
addressed. In the late 1980s, James
Watson, in initiating the Human
Genome Project, announced that several
percent of the funds for the project
would go to addressing the ethical, legal,
and social implications of the research
(Beckwith 1991). Organizations of
scientists such as Science for the People,
the Council for Responsible Genetics,
and the Union of Concerned Scientists
have challenged an array of uses of
science and technology that were
considered to have potentially harmful
results. These activities are important
because it is often the scientists who
may be better able to anticipate
problems and to help the public
understand technical aspects of the
research.
But this undercurrent of responsibility is
thin. The majority of scientists continue
their scientific research careers with
little regard for the potentially harmful
consequences of their own work or of
work in their field. Or worse, they may
contribute (unwittingly or not) to the
potential for harm through their own
public statements or participation in
public discussion.
Today, as reflected in Jurassic Park and
other works of science fiction, the
science of genetics most prominently
presents society with a double-edged
sword. Fortunately, there is the
opportunity for geneticists to become
sensitized to these problems through a
study of a time past when genetic
science played a large social role.
With regard to genetics, there are
striking parallels between conditions
today and in the early part of this
century in the United States. In both
periods, dramatic breakthroughs
generated highly productive periods in
genetics research. In 1900, the
rediscovery of Mendel's laws opened up
the field of genetics as we now know it.
Today, we see an era in which technical
developments ranging from
recombinant DNA to DNA sequencing to
the polymerase chain reaction have
produced a revolution in the ease with
which genetic problems can be
addressed. In the early 1900s, the new
era in genetics was accompanied by a
powerful eugenics movement that
influenced social policy. Today, the
increasing focus on genetics both within
biology and in the media is beginning to
shift public attention to genetic
explanations and genetic solutions to
health problems and social problems.
From an examination of this history, we
can learn much about the role of
scientists' participation in work with
socially harmful effects. We can also
explore how science is transmitted to the
public and the responses of scientists to
potential or actual harm resulting from
work in their field.
The eugenics movement in the
United States
In the early 1900s, the burgeoning field
of genetics was quickly incorporated
into the eugenics movement (Chase
1977, Kevles 1985, Ludmerer 1972). The
origins of this movement are complex,
evolving in part from a cattle breeding
association and led by a number of men
from the upper social classes.
Prominent aristocratic figures in the
eugenics movement such as Madison
Grant, author of the popular eugenics
book The Passing of the Great Race
(1916), and Robert DeCourcy Ward, a
leader of the Immigration Restriction
League, used the new concepts of
genetics to support their claims for the
inferiority of certain ethnic groups and
of the lower social classes. But, more
important for our purposes, many of the
leading geneticists supported the
eugenicists or even became active in the
enterprise. According to Kenneth
Ludmerer (1972), in the early days
(1906-1915) of this movement most of
the leading geneticists were seduced by
or promoted eugenic theory.
For instance, every member of the first
editorial board of the journal Genetics
(founded in 1916)--Thomas Hunt
Morgan, William E. Castle, Edward M.
East, Herbert S. Jennings and Raymond
Pearl--gave support to the eugenics
movement. Pearl stated, "I doubt if
there is any other line of thought or
endeavor on which common
international discussion and action can
be so well and so profitably brought
about as with eugenics" (author's
emphasis) Michael Guyer (a confirmer
of Mendelian theory) worried that "our
very civilization hangs on the issue"
(Ludmerer 1972, p.35). East (who
ultimately showed that many traits were
determined by multiple genes) felt that
without eugenics "man's troubles will
speedily multiply as they never have
before" (Ludmerer 1972, p.37).
Textbooks in genetics, written by
eminent geneticists such as Harvard's
Castle, included sections on eugenics.
Either straight eugenics courses or
courses that included sections on
eugenics were taught in three-quarters
of all colleges and universities in the
country (Allen 1975, Ludmerer 1972).
Yet, the new so-called science of
eugenics, was, in retrospect at least,
based on shoddy and primitive scientific
analysis. For instance, Charles
Davenport, who had done impressive
scientific work in showing that
Huntington's Disease was inherited as a
dominant Mendelian trait, also argued
that social phenomena such as
criminality, poverty, intelligence, and
even seafaringness could be attributed
to single genes (Ludmerer 1972). These
conclusions were often based on nothing
more than crude family studies or
population-based use of IQ tests. Even
less evidence was used to argue that
reproductive intermingling of different
racial and ethnic groups would lead to
inferior progeny (Provine 1973).
However, it is unlikely that the nature of
the science alone explains the
prevalence of eugenics ideology among
geneticists. The leading geneticists of
this period came mainly from the upper
social classes, descendants of early
American ancestors (Ludmerer 1972).
At a time of considerable social turmoil,
labor strife, and major immigration
movements, explanations for social
phenomena that took away the
responsibility for problems from those
governing the society and attributed
them to the genetic defects of
individuals or groups must have been
soothing to those in the upper echelons
of society. Rather than having to
surrender any privilege, this class could
look on eugenics as a solution.
Why did so many scientists promote
eugenic theories, given the weakness of
the underlying science? Perhaps if we
can understand this phenomenon, we
will be better prepared to anticipate and
avoid such trends today. The early days
of genetics were a series of successes
where one after the other simple trait
was shown to follow Mendel's laws of
inheritance. From Mendel's pea plants
to traits of the fruit fly Drosophila to
human metabolic disorders such as
alkaptonuria, the concept of single-gene
determinants appeared to hold sway.
This unquestionably powerful new
analytic tool may have generated an
overweening confidence among
geneticists that led them to imagine that
the same approaches could be used to
explain more complex human traits.
Simplification and reduction are natural
tendencies within science. The
attraction of theories that are allexplanatory is often too much to
withstand.
However, this analysis cannot explain all
the various strands of the eugenics and
anti-immigration movement. At various
points, these movements included major
figures in the labor movement and
socialists such as Margaret Sanger.
Furthermore, eugenics ideology was
strong among socialists in both
Germany and the Soviet Union (the
latter until Lysenkoism took power;
Graham 1977).
At any rate, this combination of a social
movement and an apparently scientific
base allowed the eugenicists to have
significant social impact (Allen 1975,
Chase 1977, Kevles 1985, Ludmerer
1972). The push for eugenics programs
played a role in both state and federal
legislation that affected people's lives. A
majority of states passed laws that
allowed sterilization for low intelligence,
certain kinds of criminality, and other
characteristics. These laws were based
on the claims of eugenicists that these
traits were genetically determined.
Many states also passed miscegenation
laws forbidding marriage between
individuals of different races, based on
flawed scientific theories of the
inferiority of hybrid races. Finally, the
United States Congress passed the
Immigration Restriction Act of 1924,
which dramatically reduced the number
of people allowed in the country from
Southern and Eastern Europe and from
other cultures considered inferior.
Although the factors leading to the
passage of this bill were many,
eugenicists played a significant role in
mustering support for it.
An important key in generating the
atmosphere in which such legislation
became possible was the development of
popular attitudes toward the issues
eugenicists were promoting. These
attitudes are often fostered by the
popular press and by other societal
institutions. The eugenics movement
presented its views to the public in many
ways. From the presentation of eugenic
displays at county and state fairs to the
teaching of eugenics in colleges and
"Going through Ellis Island" (describing
the characteristics of various immigrant
groups; 82: 5-18)
"A study in Jewish psychopathology"
(82: 264-271)
"Heredity and the Hall of Fame" (82:
445-482)
"The biological status and social worth
of the mulatto" (82: 573-582)
"Heredity, culpability, praiseworthiness,
punishment and reward" (83: 33-39)
"Eugenics with special reference to
intellect and character" (83: 125-138)
universities, various sectors of society
were exposed to eugenics science and
theories (Allen 1975). The
communication of these theories was
spread even more widely by its
appearance in the popular magazines of
the day. Articles with titles such as
"Decadence of human heredity" in the
Atlantic Magazine in 1914, (vol. 114,
p.302) ,"Plain remarks on immigration
for plain Americans" in the Saturday
Evening Post in 1921 (Chase 1977,
p.255), and " Danger that world scum
will demoralize America" in the Boston
Herald in 1921 (Chase 1977, p. 173)
helped to strengthen eugenic attitudes
among the public.
An examination of Popular Science
Monthly, edited by respected
psychologist James McKeen Cattell,
from the years 1913 and 1915
demonstrates the influence of
eugenicists on popular culture. The
following articles all reflected the
position of the eugenics movement of
that time:
"Immigration and the public health"
(83: 313-338)
"A problem in educational eugenics"
(83: 355-367)
"Economic factors in eugenics" (83: 471483)
"The racial element in national vitality"
(86: 331-333)
"Eugenics and war: the dysgenic effects
of war" (86: 417-427)
"Families of American men of science"
(86: 504-515)
"Biological effects of race movements"
(87: 267-270)
A few examples from these articles gives
a sense of this "popular science." A
report on "Jewish psychopathology"
argues that "Jews are a highly inbred
and psychopathically inclined race" (vol.
82, p. 265) and that "Among the frankly
feeble-minded, the Jews stand next to
the top of the list of those immigrants
who are deported on that account" (p.
269). David Starr Jordan, evolutionist
and president of Stanford University, in
"Biological effects of race movements,"
spoke of the "lower races" that were
immigrating into the United States from
Europe and Asia and lowering "our own
average" (vol. 87, p. 270). H. E. Jordan
of the University of Virginia in "The
biological status and social worth of the
mulatto" cites geneticists Davenport and
Karl Pearson in concluding that "negro
traits (e.g. cheerful temperament, vivid
imagination...) are of the nature of unit
characters [i.e., Mendelian traits]" (vol.
82, p. 580).
Thus, the evolution of the eugenics
movement proceeded from academic
theorizing and academic
pronouncements, to their translation to
the public via the media and other
institutions, and, finally, with the
appropriate public attitudes generated,
to the formulation of social policy.
Eugenicists and psychologists active in
the mental testing movement were well
mobilized for these political activities.
By the time the eugenics movement had
reached its peak, many of the geneticists
had withdrawn their backing. This
falling off of scientific support, however,
had little effect on the implementation
of eugenics policies. Geneticists
generally stayed away from the fray,
even though they recognized the harm
that was being done. They rarely spoke
out against these policies, and, by the
time they did, it was essentially too late
(Allen 1975, Ludmerer 1972). For
instance, East, Castle, and Jennings
began to criticize the eugenically based
Immigration Restriction Act and the
arguments that had been put forth for
many years only at about the time the
act was being passed by Congress.
The studies and proclamations of the US
eugenicists were also closely followed in
Germany in the 1920s and 1930s. The
perhaps most widely used text in human
genetics during this period was by the
prominent German geneticists Fritz
Lenz and Erwin Baur and German
anthropologist Eugen Fischer (Baur et
al. 1931). This book, which used data
and conclusions from US mental testers
such as L. Terman and E. L. Thorndike
and US eugenicists such as Davenport,
was a eugenics and biological
determinist text. It contained
characterizations of races and ethnic
groups as exhibiting certain genetically
based personality traits:
"Fraud and the use of insulting language
are commoner among Jews" (p. 681)
"In general, a Negro is not inclined to
work hard..."(p.628)
[T]he Mongolian character...inclines to
petrifaction in the traditional" (p. 636)
"The Russians excel in suffering and in
endurance..." (p.639)
"[I]n respect of mental gifts the Nordic
race marches in the van of mankind" (p.
655)
Members of the German "Racial
Hygiene" movement pointed to the laws
and influence of the US eugenics
movement as support for their positions
(Muller-Hill 1988, Proctor 1988,
Waldinger 1973). As in the United
States, many scientists were ardent
supporters of these policies (Muller-Hill
1988).
With the extreme misuse of genetics by
German scientists and finally the Nazi
government, some English and US
geneticists began to speak out more
openly. At the seventh International
Congress of Genetics in 1939, a number
of geneticists issued a manifesto
criticizing eugenic programs (Crew et al.
1939). Among the signers were J. B. S.
Haldane, J. S. Huxley, H. J. Muller, T.
Dobzhansky, and A. G. Steinberg,
several of whom, although they still held
eugenics views themselves, were
appalled by the implementation of
eugenics in Germany. For the most
part, the opposition of geneticists to the
misapplication of their field was too
little and too late, and it had a minimal
effect.
Recent history
The universal revulsion at the Nazi
eugenics policies after World War II led
to a rejection of many of the general
claims of the eugenics movement. In
particular, the position that human
behavioral traits and social problems
had their origins in genetics was
replaced by the position that
environment was the determining factor
in such issues. Some of these positions
are reflected in two statements issued by
UNESCO in the early 1950s. One of
these, prepared by leading physical
anthropologists and geneticists (several
of them from the group that wrote the
1939 statement), criticized the concept
of race and argued that differences in
culture, intellectual achievement, and
behavior between ethnic groups were
not genetic in origin (Montagu 1963).
However, beginning in the late 1960s,
scientific arguments for a genetic basis
for various behavioral traits began to
attract increasing attention. One of the
earliest and most dramatic of such
claims was the proposal that males with
an extra Y chromosome (XYY males) are
more aggressive than the average male
(Jacobs et al. 1965) and exhibit a
susceptibility to lead criminal lives
(Price and Whatmore 1967). Despite the
weakness of the initial evidence, the
myth of the "criminal chromosome"
took hold of the public imagination
(Pyeritz et al. 1977). Within a few years
of the first findings, it became clear that
XYY males were neither hyperaggressive
nor doomed to lives of criminality
(Bender et al. 1984, Borgaonkar and
Shah 1974, Theilgaard 1983, Witkin et
al. 1976; see most recently Evans et al.
1991). But by the time these conclusions
were reached, the XYY myth was already
being presented as fact in everything
from high school biology texts to
medical school psychiatry texts.
There followed other controversial
claims of evidence for a genetic basis for
black-white differences in performance
on IQ tests (Jensen 1969), for boy-girl
differences in performance on
mathematical examinations (Benbow
and Stanley 1980), and for a host of
human behavioral traits including male
dominance, xenophobia, religiosity, and
shyness (Bouchard et al. 1990, Wilson
1975). The XYY research was carried
out for the most part by geneticists, but
the remaining studies were the work of
psychologists or students of animal
behavior. Thus, there was little
involvement of the genetics community
in the resurgence of interest in genetic
explanations of human social behavior
and aptitudes.
The recombinant DNA era and
the Human Genome Project
Although it is possible that the
molecular biology of the 1950s and
1960s generated an environment in
which reductionist approaches to a wide
range of problems seemed appropriate,
the breakthroughs in genetics in the
1970s have even more clearly created
such an environment. The
improvements in DNA sequencing
techniques, the development of
recombinant DNA approaches to gene
cloning and manipulation, and a host of
further advances have made simpler the
genetic approaches to biological
problems in any organism, including
humans. The successes in biology based
on this progress have been
extraordinary. A partial list of such
achievements include mapping and
characterization of genes involved in
numerous genetic diseases, working out
of developmental pathways at the
genetic level in several organisms,
refinement of evolutionary trees based
on DNA sequence homology, and an
extraordinary increase in the
understanding of the development and
functioning of the immune system.
As a result of the technological
breakthroughs, biology's focus has
shifted dramatically to the analysis of
genes. This shift has been
extraordinarily productive and exciting.
The reductionist approach of focusing
on genes has worked for a host of
previously intractable biological
problems. However, accompanying this
transformation of biology has been a
strengthening of an extreme
reductionist position toward both the
science itself and its social applications.
As with the period that initiated genetics
at the turn of the century, the successes
of the science have been translated into
a world view. First, some molecular
biologists have implied that essentially
all biological problems are best
approached by studying genes. For
instance, according to Walter Gilbert
(1991), "To identify a relevant region of
DNA, a gene, and then to clone and
sequence it is now the underpinning of
all biological science."
Second, many leaders of the revolution
in molecular biology have publicly
claimed a nearly all-explanatory role for
genetics. Many of these claims have
been associated with the initiation of the
Human Genome Project. James Watson
was quoted in Time magazine, "We used
to think our fate was in our stars. Now
we know, in large measure, our fate is in
our genes" (Jaroff 1989, p. 67). Norton
Zinder calls the human genome
sequence a "Rosetta Stone" (Hall 1990,
p. 42), whereas Walter Gilbert termed it
the "Holy Grail of genetics" (Hall 1990,
p. 42). Gilbert also stated that from the
sequence "we can have the ultimate
explanation for a human being"
(DelGuercio 1987).
Robert Sinsheimer says that the
sequence is what "defines a human
being" (Hall 1988, p. 64). Charles
DeLisi entitled a subsection of his article
on the Human Genome Project "The
blue print for life" (DeLisi 1988). Paul
Berg stated at a recent Stanford
conference, "Many if not most human
diseases are clearly the result of
inherited mutations" (Berg 1991).
Frances Collins suggests that "[The
Human Genome Initiative] will likely
transform medicine in the 21st century
into a preventive mode, where genetic
predispositions are identified and
treated before the onset of illness rather
than after illness is under way" (Collins
1991).
In an editorial in Science magazine and
elsewhere, Daniel Koshland argued that
the Human Genome Project will provide
solutions to many of our social
problems, including homelessness
(Koshland 1989). "The homeless
problem is tractable. One third of
homeless are mentally ill--some say
50%. These are the ones who will most
benefit from the Genome Project"
(Koshland 1991). Koshland's rationale is
that mental illness has a genetic basis
and that finding the postulated genes for
mental illness will allow cures to be
developed.
These attitudes toward the future of
biology and its relevance to social
problems reflects, as Levins and
Lewontin have put it, "the confusion of
reduction as a tactic with reductionism
as an ontological stance" (Levins and
Lewontin 1985). That is, the remarkable
successes of genetics in approaching a
number of biological and medical
problems have been translated into a
view in which genetics is the strategy of
choice in biology and the explanatory
framework for society's medical and
social problems. But the movement
within biology to concentrate on genes
as the basis of all biological studies is a
myopic view of the field. The questions
we study in biology arise in many
different ways. Some come from the
discovery of new genes, but many others
are only made possible because of years
of descriptive work.
There are many complex basic and
applied problems that require
approaches other than genetics.
Although the improvement in genetic
techniques has occurred at an incredibly
rapid pace, comparable improvement in
techniques of cell biology have been
neglected. The greatest rewards in
biology today come for those working in
the areas of DNA and gene
manipulation.
The devaluing of descriptive biological
work and of technical innovations in
such areas as electron microscopy could
ultimately lead to a drying up of the
source of the very information that is
needed to make sense of genetic studies
or even to stimulate new areas of genetic
research. The training of students in the
latest technological developments to the
detriment of broader biological training
could also contribute to an
impoverishment of the field. Molecular
biologists should not be blinded by the
dazzling successes of genetics to the
balance in approaches that are required
for future progress.
The translation of the reductionist
approach to an analysis of everything
from human health to the human
condition is also problematic. The
arguments about health are based, in
part, on the finding that some instances
of susceptibility to common diseases
such as heart disease or cancer are
correlated with the inheritance of an
altered gene. It is likely that more such
instances will be found. However, such
findings do not imply that most cancer
or most heart disease is related to such
susceptibility genes. Further, in those
cases where there is a susceptibility, it is
usually only a susceptibility. The actual
development of cancer will be due to
many factors, including other genes and
the environment. It is not at all clear
that the best way to approach cures or
prevention of cancer is a study of a
cancer gene, as opposed to systematic
analysis of environmental factors and
the many other approaches that are
currently employed in studying this
problem.
This area is full of uncertainty. There
are few examples that would give us
confidence that gene characterization
will lead to solutions to health problems.
For instance, researchers have
understood the molecular basis of
sickle-cell anemia in terms of the amino
acid change in the hemoglobin protein
for more than three decades (Ingram
1957), but it has been continuing
medical studies on the progress of the
disease rather than genetic knowledge
that has contributed to the significant
improvements there have been in
survival and health of those suffering
from the condition (Kolata 1987). It is
only quite recently that the molecular
genetic studies have begun to bear fruit
in this area (Leery 1993).
Of even more concern are the claims
concerning genetics and social problems
such as homelessness (Koshland 1989).
It is useful to analyze the content of such
claims. First, a social problem is
relegated to the realm of medicine or
biology when the roots are often in
failings of the society itself. Clearly,
some of the homeless do have severe
mental problems, but much
homelessness has its roots in economic
deprivation. Second, the reliance on
genetics to account for mental disorders
exaggerates and distorts what we know.
There is relatively convincing evidence
that, for example, some cases of manic
depressive illness have a heritable
component, although a gene has yet to
be discovered; but this evidence does
not mean that all manic depressive
illness can be traced to genes and
certainly not that all depression has a
genetic basis. Furthermore, even in
those cases where there is substantial
evidence for manic depressive illness
having a genetic correlate in certain
families, it is clear that not everyone
who inherits the susceptibility develops
the disorder. It seems likely that
environmental factors are also
important and should be explored in
considering how to deal with the
disorder.
Third, the fact that a gene plays a role in
a particular disease does not necessarily
imply that genetics will provide
solutions. As discussed above, although
finding a gene for a particular condition
will certainly promote better
understanding of that condition, there is
no certainty that cures or treatments will
be generated. Finally, the recent
molecular genetic searches for genes
related to such conditions as manic
depressive illness, schizophrenia, and
alcoholism have suffered from much of
the same hastiness and overconfidence
that characterized the behavior genetics
of the eugenics era (Barnes 1989, Baron
et al. 1990, Billings et al. 1992).
Fortunately, molecular genetic studies
are more easily replicable, and, as a
result, mistaken conclusions have been
rapidly picked up. The problems with
the current attempts to discover genes
for these complex behavioral traits has
led to suggestions that the search will be
long and arduous and to restoring of
some balance in examining genetic and
environmental contributors.
Consequences of biological
determinist attitudes
In the last 15 years, the public has not
only witnessed an explosion of genetic
information but also has been deluged
with reports of the discovery of genes for
everything from cystic fibrosis to
alcoholism. These are exciting times,
and the publicity for the achievements of
genetics is warranted. But, what kind of
environment is now being generated by
the publicity that genetics has achieved
with the grandiose claims that
accompany it? One effect of this
publicity has been to promote the
conception that genetics is allexplanatory. Reductionist statements
from scientists of the sort quoted above
only reinforce a distorted perception of
the basis of the human condition. Genes
are used in the popular media more and
more to explain social phenomena.
Everything from the attitudes of TV
critics (Stewart 1991) to the basis of
violence among soccer fans in Great
Britain (Lehmann Haupt 1992) to
presidential candidate Ross Perot's
frugality (Wright 1992) are ascribed to
genes. As in the early part of this
century, the media is serving as a means
of transmission of the perspective of
scientists and, thus, helping form public
opinion that can influence social policy.
It may be that the increased attention to
genetics in society will give greater
courage to those who argue that our
social problems and social inequities are
genetic in origin. For example, recent
reports of gene discoveries have been
used to support the arguments made by
proponents of human sociobiology in
the 1970s. A number of sociobiologists
received considerable public attention
for their suggestions that such social
characteristics as xenophobia, male
dominance, and class structure were
genetically based. In 1988, Melvin
Konner (Konner 1988), one of the
contributors to this field, referred to the
mapping of genes for Huntington's
disease ( Gusella et al. 1983) and manic
depressive illness (Egeland et al. 1987)
as a refutation of the critics of
sociobiology. (The report of the
mapping of the manic-depressive-illness
gene was later retracted; Kelsoe et al.
1989.) These discoveries were seen by
Konner as showing that human behavior
was strongly influenced by genes, and
thus, by inference, providing greater
support for sociobiological theories of
human behavior.
The reawakened interest in issues of
genetics, human behaviors, and social
policy is also reflected in the resurgence
of academic controversy over arguments
that blacks are genetically inferior to
whites in intelligence (Allen 1992,
Anderson 1990, Holden 1991, Kaufman
1992, Maddox 1992, Palca 1989, Selvin
1991a,b). It may be that the
reappearance of this controversy is
facilitated by the climate in which
genetics is made to appear more and
more important. Of course, racism is
not generated by genetics, and an
important source of the renewed interest
in these issues arises out of the political
climate, including the debate over
affirmative action. But, historically,
arguments from the scientific
community have provided important
support for racist ideology and political
action.
Overall, then, overextension of the
applications of genetics can have
profound effects on society. In general,
the focus on genetics alone as
explanatory of disease and of social
problems tends to direct society's
attention away from other means of
dealing with such problems. At its
extreme, a false hope of cures for disease
distorts the distribution of resources.
Genetic explanations for intelligence,
sex role differences, or aggression lead
to an absolving of society of any
responsibility for its inequities, thus
providing support for those who have
interest in maintaining these inequities.
They can influence the development of
social policy in such areas as education.
In the early 1970s, arguments for
genetically based racial differences in
intelligence were used as a justification
for the dismantling of compensatory
education programs and in school
desegregation controversies. Claims for
women's inferiority in mathematics
ability influenced the attitudes of both
female students and their parents.
Genetics has also intruded into
discussions of the problem of crime in
the United States. The temporary ado
about XYY males led to screening
programs of both newborns and juvenile
delinquents in some states. We may not
have to worry about a eugenics program
in this country in the foreseeable future,
but the other consequences of
misguided biological determinist claims
are severe enough. (It should be noted
that eugenics programs are in effect in
some societies such as Singapore, where
scientific studies from the United States
are marshaled in support of the policy;
Nature 1984.)
The future
An examination of the history of
genetics and its relationship to social
issues holds many lessons. First, the
work of geneticists can ultimately be
translated into social policy, sometimes
with deleterious consequences. These
consequences may occur with the active
participation of scientists themselves.
In the eugenics movement of the early
part of the twentieth century, geneticists
played a significant role. But even
geneticists who are not committed to a
public role in influencing social policy
may still contribute to the potential
repercussions by their public
statements.
Second, statements by geneticists, with
or without their active participation, are
rapidly translated for the public. This
translation occurs, in part, by the
popular media's representation of
scientific advances and scientists' views.
Today's geneticists, caught up in the
enthusiasm of the successes of the new
molecular biology, are contributing to an
unbalanced view of the role of genetics
and environment. A climate is being
created in which social policy and
individual attitudes may be formulated
on the basis of incomplete or incorrect
views of the human condition. Care for
the way in which genetics is presented to
the public and involvement in
countering any misrepresentations is a
responsibility of the genetics
community.
Finally, the history of eugenics and its
disastrous consequences raises the
question of the role of the genetics
community in dealing with the social
impact of its field. Even after they
became disaffected from the science and
politics of the eugenics movement,
geneticists did little to blunt its effects.
It seems likely to me that if geneticists
such as Morgan and Castle had spoken
out loud and often of their disdain for
eugenic science, the outcome might well
have been different.
Today, dealing with the concerns about
the social consequences of the new
genetics and the Human Genome
Project is being relegated, for the most
part, to ethicists, social scientists,
lawyers, and other nonscientists. Yet,
those involved in the science have a key
role to play and a responsibility to
ensure that progress in their field is not
used to harm rather than benefit people.
This role calls for more knowledge of
history and less hubris.
