Assessing
the risk
A
As a title for a supposedly unprejudiced debate on
scientific progress, “Panic attack: interrogating our obsession with risk” did
not bode well. Held last week at the Royal Institution in London, the event
brought together scientists from across the world to ask why society is so
obsessed with risk and to call for a “more rational” approach. “We seem to be
organising society around the grandmotherly maxim of ‘better safe than sorry’,”
exclaimed Spiked, the online publication that organised the event. “What are
the consequences of this overbearing concern with risks?”
B
The debate was preceded by a survey of 40 scientists who
were invited to describe how awful our lives would be if the “precautionary
principle” had been allowed to prevail in the past. Their response was: no
heart surgery or antibiotics, and hardly any drugs at all; no aeroplanes,
bicycles or high-voltage power grids; no pasteurisation, pesticides or
biotechnology; no quantum mechanics; no wheel; no “discovery” of America. In
short, their message was: no risk, no gain.
C
They have absolutely missed the point. The precautionary
principle is a subtle idea. It has various forms, but all of them generally
include some notion of cost-effectiveness. Thus the point is not simply to ban
things that are not known to be absolutely safe. Rather, it says: “Of course
you can make no progress without risk. But if there is no obvious gain from
taking the risk, then don’t take it.”
D
Clearly, all the technologies listed by the 40 well-chosen
savants were innately risky at their inception, as all technologies are. But
all of them would have received the green light under the precautionary
principle because they all had the potential to offer tremendous benefits – the
solutions to very big problems – if only the snags could be overcome.
E
If the precautionary principle had been in place, the
scientists tell us, we would not have antibiotics. But of course, we would – if
the version of the principle that sensible people now understand had been
applied. When penicillin was discovered in the 1920s, infective bacteria were
laying waste to the world. Children died from diphtheria and whooping cough,
every open-drain brought the threat of typhoid, and any wound could lead to
septicaemia and even gangrene.
F
Penicillin was turned into a practical drug during the
Second World War when the many pestilences that result from were threatened to
kill more people than the bombs. Of course antibiotics were a priority. Of
course, the risks, such as they could be perceived, were worth taking.
G
And so with the other items on the scientists’ list:
electric light bulbs, blood transfusions. CAT scans, knives, the measles
vaccine – the precautionary principle would have prevented all of them, they
tell us. But this is just plain wrong. If the precautionary principle had been
applied properly, all these creations would have passed muster, because all
offered incomparable advantages compared to the risks perceived at the time.
H
Another issue is at stake here. Statistics are not the only
concept people use when weighing up risk. Human beings, subtle and evolved
creatures that we are, do not survive to three-score years and ten simply by
thinking like pocket calculators. A crucial issue is the consumer’s choice. In
deciding whether to pursue the development of new technology, the consumer’s
right to choose should be considered alongside considerations of risk and
benefit. Clearly, skiing is more dangerous than genetically modified tomatoes.
But people who ski choose to do so; they do not have skiing thrust upon them by
portentous experts of the kind who now feel they have the right to reconstruct
our crops. Even with skiing, there is the matter of cost-effectiveness to
consider: skiing, I am told, is exhilarating. Where is the exhilaration in GM soya?
I
Indeed, in contrast to all the other items on Spiked’s
list, GM crops stand out as an example of a technology whose benefits are far
from clear. Some of the risks can at least be defined. But in the present
economic climate, the benefits that might accrue from them seem dubious.
Promoters of GM crops believe that the future population of the world cannot be
fed without them. That is untrue. The crops that really matter are wheat and
rice, and there is no GM research in the pipeline that will seriously affect
the yield of either. GM is used to make production cheaper and hence more
profitable, which is an extremely questionable ambition.
J
The precautionary principle provides the world with a very
important safeguard. If it had been in place in the past it might, for example,
have prevented insouciant miners from polluting major rivers with mercury. We
have come to a sorry pass when scientists, who should above all be
dispassionate scholars, feel they should misrepresent such a principle for the
purposes of commercial and political propaganda. People at large continue to
mistrust science and the high technologies it produces partly because they
doubt the wisdom of scientists. On such evidence as this, these doubts are
fully justified.

the survey were sending was people shouldn’t take risks.
4..................... All the 40 listed technologies are riskier
