The Zero Risk Fiction by Thomas R. DeGregori

By ACSH Staff — Apr 24, 2002
Arguments against constructive change take many forms. One is what I have called the myth of the "riskless alternative." Every change has its risks, whether the change is political, scientific, or technological, but a simple assertion of risk is not in and of itself an argument against change.

Arguments against constructive change take many forms. One is what I have

called the myth of the "riskless alternative." Every change has its risks,

whether the change is political, scientific, or technological, but a

simple assertion of risk is not in and of itself an argument against

change.

The risks of change have to be measured against the benefits of change and

the risks of not changing. Increasingly, we hear impossible demands for a

zero-risk society. In public discourse, scientists are asked to guarantee

that an innovation, be it genetically-modified food or a new

pharmaceutical, has no possibility of ever causing harm. Given that no

reputable scientist can ever answer such a question with absolute

certainty, the interrogator has seemingly won the argument by default - if

one believes that there is some totally risk-free alternative, either in

the status-quo or in some presumed prior way of doing things.

Opposition to change in favor of the status-quo-ante used to be considered

a conservative or reactionary position; now it has become the battle cry

of presumptive radicals from the streets of Seattle to those of Genoa and

beyond. Having "won" the argument by showing that safety cannot be

guaranteed with absolute certainty, the believers feel no need to subject

their proposed alternatives to the same tests, tests that would often

reveal that the radicals' plans carry far more risks than the innovations

they oppose.

Along with "riskless" change, there are now demands for "victimless"

change. Unfortunately, if there are possible risks, there are always

possible victims. If we examine the many changes over the past century

changes that have reduced infant and child mortality over 90%, have given

Americans nearly thirty years of added life expectancy, have recently

caused an even more rapid growth in disability-free years of life, and

have allowed comparable or greater advances in other countries we will

find that all those changes carried risks. Indeed, all those changes had

and continue to have organized opposition: chlorination of water,

pasteurization of milk, synthetic fertilizers, chemical pesticides, modern

medicine, and immunization, to name a few. Pasteurization took nearly

fifty years to be introduced into the United States and the arguments

against it were identical to those used today against food irradiation.

Most every health intervention carries some risk, but those that we have

come to depend upon carry vastly fewer risks than the threat to life and

good health from the diseases that they protect against. But again,

nothing in life carries zero risk (although some vaccines seem to be

getting very close to that). I have a question that I have been asking for

over a quarter of a century: If technology and science are killing us, why

are we living so long?

Infant and child mortality and morbidity have so successfully been reduced

that we, individually and collectively, forget the scourge of the diseases

against which we are now protected. Unfortunately, infants and children

still suffer from other maladies, many with uncertain causes. Since

infants are given a regimen of eleven successive immunizations, it is not

surprising that some shots happen to coincide with the onset of an

unexplained malady. The anti-science and anti-technology coterie are quick

to assign the blame to immunization without a scintilla of evidence, and

they frighten parents into not immunizing their children. The evidence is

overwhelming that a decline in immunization will eventually lead to an

increase in disease, often with death or permanent health impairment

following in its wake. In the United Kingdom and Germany, some of these

fears have led to declines in immunization, which have lowered the

immunization rate perilously close to the minimum necessary for "herd" or

"community" immunity. That could lead to epidemics of diseases such as

measles.

There is a role for the genuine radical in calling attention to victims of

change, encouraging us to ask, for instance, whether the costs of change

are falling unfairly upon certain groups or individuals. Focusing on the

victims and the risks sometimes helps us find ways to reduce the adverse

outcomes (by making our vaccines ever safer, for instance). The smallpox

vaccination that I received as a boy had more antigens than the combined

total of all eleven vaccines that are administered to infants and children

today. Those who were harmed by the vaccinations obviously knew it, while

the vastly greater number who didn't get smallpox (or any other disease

against which we were protected) went on with their lives without thinking

about the horrors they might have suffered without the vaccinations.

One of the problems in defending modern science and technology against its

critics is that so many of the benefits are unseen: nasty things that

don't happen to us. Suppressing a technology such as immunization creates

far more victims that does utilizing it. In other areas, such as

globalization of the world economy, it is not only who is harmed that

matters but who and how many benefit. Unfortunately, globalization

critics, as is increasingly the case for the critics of most of the

modernizing transformations, provide us with a litany of victims or

alleged victims without noting the many beneficiaries, such as the

hundreds of millions of people who have been able to rise out of poverty

as a result of having their economies opened to change. There is a kind of

Gresham's Law of social protest whereby the increasingly strident

opposition to all globalization drowns out more reasoned arguments for

making globalization fairer.

Wealthy advocacy groups largely controlled by white, northern-European and

North American males with sophisticated command of public relations and

media access have created a new form of neo-colonialist imperialism,

hijacking the political agendas of many oppressed peoples and misusing the

suffering of those people to oppose globalization and change. With six

billion people in close to two hundred sovereign political entities, the

world is replete with injustices, legitimate grievances, and indigenous

groups seeking a just remedy for them. Tragically, they are not able to

get a hearing in the media without the aid of the developed countries'

advocacy groups. Those advocacy groups demand that the poor of other

nations make their claims using slogans that conform to their own ideology

and fund-raising needs. To draw media attention to poverty in a southern

nation, local activists may have to conform to the party line of northern

groups such as Greenpeace. Thus, their real grievances are diluted or lost

as are the grievances of any groups pressured to use the litany of

political complaints favored by wealthy countries' elite activist groups.

Justice requires that the poorest and most needy in the world have the

opportunity to experience the changes that have benefited the rest of us.

They should not be hindered by groups that oppose change for others while

enjoying it themselves. Taking reasonable risks turns out to provide us

all with greater safety. Those who would force us to pursue the impossible

goal of absolute safety put us all in greater jeopardy. --
