Vol. 300, No. 5618
A review of James D. Watson, with Andrew Berry, DNA: The
Secret of Life (New York: Knopf, 2003), and Victor K. McElheny,
Watson and DNA: Making a Scientific Revolution (Cambridge,
MA: Perseus, 2003)
The time has come, in the world of James D. Watson, to leave
behind societal fears of genetic technologies. It is time to
start using germ-line genetic engineering to make people who
are more intelligent, more attractive, and resistant to HIV.
It is time to use genetically modified organisms to improve
the environment and end world hunger. And it is time for everyone
to contribute their DNA to databases, both private and public.
Fortunately, there is no need to worry too much about abuse,
injustice, commodification, technical error, or social stratification
grounded in biological difference. Such worries are groundless
because science shows that people are biologically inclined
to care about one another and to care about building a good
society. The Bible also mentions how important human love is.
Despite their propensity for caring, of course, people are
often fanatical, unscientific, ignorant, dishonest, prone to
"Luddite paranoia," irrational, and unwilling to accept
the true facts that science reveals--as Watson notes in his
latest public promotion of genomics, DNA: The Secret of Life.
People just need to stop worrying so much about power and money.
It is true that politics and economics do drive science, but
Watson insists that they should be irrelevant to its assessment.
And people also need to stop worrying so much about "the
human spirit." The idea that there "is no gene for
the human spirit" reflects irrational prejudice. People
wish that there were no such gene and this constitutes "a
dangerous blind spot in our society." In any case, back
in 1953, molecular ghostbusters Watson and Crick cleared out
any spirits that might be hanging around inside the cell: "Is
there something divine at the heart of a cell that brings it
to life? The double helix answered that question with a definitive
No."
I have just summarized the normative framework that drives
Watson's book. The alert reader might well ask how such a convoluted
nexus of belief and prophecy could gain cultural legitimacy,
or even a sympathetic publisher. What forces made this incoherent
tangle of mysticism, historical ignorance, religiosity, corporatism,
exaggerated technocratic rationality, intemperance, and social
naïveté plausible to so many people? Or even to
James D. Watson? It would be comforting to attribute all to
Watson himself, but both the texts reviewed here suggest Watson
is merely a potent sign of what has happened to the biological
sciences in the last 50 years. Biology is now an important corporate
sector, and Watson is a captain of industry. Indeed, in his
latest account of himself, written with Harvard biologist Andrew
Berry, as well as in Victor McElheny's biography Watson and
DNA, Watson emerges as that richly American character, the great
salesman. And salesmen, as every attentive consumer knows, sometimes
hedge on the details.
These two books join a wave of texts and events celebrating
the 50th anniversary of the elucidation of the helical structure
of DNA. Watson's book is linked to a five-part television series
(which airs this month on PBS) and provides an overview of the
history, science, and politics of DNA. McElheny, a science journalist
who has covered molecular biology for decades and worked for
Watson at Cold Spring Harbor, finds Watson boyishly charming
and refers to him as "Jim" throughout the book. His
biography is written in strong journalistic style, thick with
quotations from people who were there. McElheny presents his
subject's life as a high-energy, high-action sequence of personal
confrontations--with nature, the Cold Spring Harbor Laboratory
advisors and investors, other scientists, Bernadine Healy at
the National Institutes of Health, ignorant critics of science,
and so on. The biography briefly touches on Watson's personal
life, but it offers little exploration of the interior person.
Watson is all gossip, public pronouncements, machinations, clever
intrigue, and shock value. The result is a fast-paced, though
flat, account intended to appeal to the general public.
Watson's own book has the same intended audience, but broader
goals. Whereas McElheny's book primarily promotes Watson, Watson's
book promotes his views of what the findings of molecular biology
tell us about ourselves and our world. It mentions data suggesting
racial differences in intelligence, sexual differences in mathematical
ability, the inheritance of genes for violence (are these on
the Y chromosome?), and the biological tendency of younger women
to marry older men (as in Watson's own life story).
Throughout his account, Watson is unconstrained by either
evidence or logic. For example, stressing that DNA predicts
just about everything, he repeats the common claim that DNA
reveals what is most important about individual human beings.
However, he also believes that no one should be too concerned
about making their own DNA freely available to the criminal
justice system, the military, employers, the education system,
health care insurers, and so on.
Anyone who is concerned about privacy, he suggests, is not
thinking clearly. In another example, he invokes the existence
of a bioethics industry to suggest that there is no reason to
get too worked up about ethical concerns: The ethicists are
on the job; the public can relax. But the reason ethicists have
taken an interest in genomics is that it is an endeavor that
could lead to practices devastating to human rights, a potential
exacerbated by the pronouncements such as Watson's. The bioethics
industry built around genomics is a sign not that the public
should be complacent, but that it should actively resist the
kinds of answers provided in Watson's book.
If Watson, for example, wants to theorize about world hunger,
perhaps he should consult the work of his fellow Nobelist Amartya
Sen. Sen has demonstrated, (through finely textured, detailed,
specific, and data-rich accounts of major famines since 1943)
that famines are not simply the result of inadequate food supplies.
They are the result of economic systems (1). People can starve
when the grain elevators are full; they can have enough to eat
when crop yields are disastrous. India, for example, has in
recent years faced dual crises of both overproduction of food
and profound malnutrition. By December 2000, millions of tons
of wheat and rice stocks were rotting in India's granaries,
while 1.5 million children were dying annually of diseases linked
to malnutrition. Promoters of genetically modified organisms
often claim that anyone opposed to transgenic crops is turning
a blind eye to the needs of those who are starving. But the
anthropologist Glenn Davis Stone has suggested that the real
moral outrage is the strategic use of hungry people to justify
corporate programs to develop these crops. "Malthusian
biotechnologists need to explain why crop genetic modification
will feed hungry Indians when 41.2 million tons of excess grain
will not" (2). Famine is an economic and political phenomenon.
It cannot, therefore, be eliminated by genetically modified
organisms or by any food product, though Watson seems to think
it can. When Watson turns to the Icelandic genome, he again
gives the story a meaning that the details cannot sustain. The
Icelandic genome was sold to investors on the premise that Icelanders
were a uniquely homogeneous population. deCODE Genetics arranged
a deal with
Iceland's parliament to construct and market to pharmaceutical
companies a database that combined Icelandic genotypes, medical
records, and genealogies. These companies could then study genetic
predispositions to common conditions such as cancer and heart
disease. But if Icelanders were no more homogeneous than any
other population, they would be far less valuable commercially
and scientifically. Einar Arnason, at the University of Iceland,
has demonstrated that Icelanders are among the most genetically
heterogeneous populations in Europe. Those who calculated Icelandic
homogeneity in the early promotional years were using public
databases of mitochondrial DNA, databases now known to be filled
with errors. Arnason tracked down the errors, proved that they
were there by contacting the original authors, and used blood
group and allozyme variation (in conjunction with more accurate
DNA data) to show that the Icelanders have experienced, unsurprisingly,
plenty of genetic admixture (3). Earlier conclusions were based,
essentially, on typographical mistakes (4, 5); as molecular
geneticist Peter Forster has wryly observed, the "postgenomic
age promises to become a proofreading age" (6). Like the
investors and the buyers, the Icelanders themselves were conned
into a corporate scheme that was the equivalent of selling swampland,
entering into arrangements that profoundly compromised their
privacy. Watson uses the deCODE story to hint at the promise
that complex, multifactorial disease genes will soon be tracked
down, profiting both patients and the biotech industry. But
the deCODE story is also about speculative hype; rapid profits
based on inaccurate information; and disadvantaged, ill-informed
patient consumers.
Similarly, Watson repeats the commonplace claim that identifying
genes which are linked to a disease leads to cures for people
who have the disease. For the last 15 years or so, the overwhelming
majority of scientific and press reports about such newly found
genes have included a suggestion that the discovery carries
us toward a cure for the relevant disease. This is ubiquitous
enough to be understood as a literary convention in genomics.
But discovered genes do not lead directly to cures (7), and
the gap between promise and performance is drawing increasing
attention from the media. Francis Collins, the director of the
U.S. National Human Genome Research Institute, has become publicly,
openly concerned about the need for an actual clinical payoff
from gene mapping. And even parents driven to hunt for genes
have found that locating the gene does not cure their children:
Brad Margus, a former shrimp merchant who has started a biotechnology
company related to genomics, has two sons with ataxia telangiectasia.
He helped raise $7 million to support the efforts to find the
gene responsible for this fatal genetic disease. Although the
gene was successfully identified in 1995, in 2000 he lamented,
"Every time I see [my sons], I know we haven't done anything,
because we haven't stopped the progression. My kids are slipping
away" (8).
Now that the sequencing of the human genome is essentially
"finished," Watson proposes that there is a new Holy
Grail--the transcriptome--that would elucidate how all genes
are expressed. Developing the transcriptome will, of course,
cost a lot of money. But like the mapping of the human genome,
it will supposedly lead to medical breakthroughs and cures.
Meanwhile, genetic disease continues to be controlled almost
entirely through the selective abortion of affected fetuses,
which in Watson's world is conflated quietly with compassionate
medical and educational intervention. So, for example, Watson
suggests that the controversial testing of school children for
fragile X syndrome is intended solely to help "tailor"
educational plans to their needs. But he also immediately points
out that each of these children costs at least $2 million more
in health care expenses than would a child without fragile X.
"The ever-increasing challenge of providing affordable
health care should itself suggest a potent argument for giving
every mother the right to be tested." The mother he refers
to is the pregnant, prospective mother, and the right to be
tested is the right to abort a fetus with fragile X. Although
selective abortion is an intervention much valued by some families
at risk, it does not constitute a cure for people who are living
with genetic diseases, many of which are disabling, painful,
and life-threatening. And Watson's invocation of health care
costs to justify testing and selective abortion is vintage eugenics.
Watson urges biologists to "stand tall" and "not
be intimidated by the inevitable criticism" that will come
with promoting germ-line gene therapy to "redress genetic
injustice." Injustice comes in many forms, of course. For
most people on the globe today, germ-line gene therapy to improve
their children is not remotely possible--their pressing health
care needs are for vaccines, nutrition, and environmental justice.
An argument could be made that health care expenditures should
reflect human needs, rather than potential corporate profits.
Celebrations this month mark both the discovery of the helical
structure of DNA and the completion of the sequencing of the
human genome. Both events should be celebrated. DNA is an important
and interesting molecule, and the map of the human genome does
provide a baseline for the elucidation of crucial questions
about evolution, development, disease, and health. The gene
map does not, however, solve all social and economic problems
or transform clinical care, and the exaggerated promotions and
insupportable claims are becoming tiresome.
Watson is fond of saying that mapping the human genome reveals
"what makes us human," and on this point I have to
agree. The genome project does reveal our extraordinary ability
to imagine and create institutions and ideologies that reflect
our social organization, our practices of commerce and trade,
and our needs. Perhaps someday, when the body's complex operations
are better understood, the knowledge the project has produced
will appear as quaint as phlogiston or mesmerism. But its organizational
and ideological qualities are timeless testimony to the nature
of the human species. They reveal our tendency to elevate what
we craft into the realm of neutral, absolute truth, and make
manifest our vulnerability to propaganda. Watson has been the
genome project's marketing director and prime salesman. His
latest promotional brochure is not worth anyone's time.
