Opinion Polls Introduction
How much does an
opinion poll influence the population at large? If
it is a poll question addresses a humorous or
trivial issue, it will be taken with a pinch of salt
- it will be treated as a joke. The accuracy of the
question will not be too relevant because of it's
nature. But what happens when the poll question
addresses a serious issue?
The
pro-fluoridation lobby certainly have a reputation
for putting a great deal of faith in fluoridation
poll questions, even to the point where they
(regularly) rig such polls to get the answer they
desire. Methods of poll-rigging are not always
clear.
Sometimes loaded
questions are asked where it is deliberately implied
that fluoridated water could reduce tooth decay.
Other poll results are distorted by the propaganda
that precedes the crucial question. This can be
actually contained within an overall questionnaire
where the question of whether to add fluoride to
water follows some less than subtle suggestions that
fluoridation is an effective way to fight tooth
decay.
On other occasions,
single poll questions on fluoride follow can be
preceded by vile and libellous public campaigns by
the poll sponsor, and aimed at those who oppose the
measure.
Something you
may not want
Trying to persuade
people they want something without actually getting
their permission to impose it upon them is not so
straightforward. For example, if you are laying out
hard cash for a product then the chances are you
would want to see a contract first. You would also
normally look for some kind of guarantee or
indemnity. The pro-fluoride lobby were in no
position to hand out guarantees about the safety and
efficacy of fluoridated water so therefore an
alternative tactic had to be employed. Enter the
spectre of the 'conveniently structured' (or even
rigged) opinion poll.
The first thing you
should realise is that an opinion poll is not a
contract. You do not 'sign on the dotted line', so
to speak. Consequently, when the person interviewed
(the respondent) states they are in favour of a
proposition, it is non-binding. In other words, it
is a subjective rather than objective approval of a
particular contention. However, and despite these
facts, the pro-fluoride lobby has used, and
continues to use, opinion polls as evidence of the
general public's approval of fluoridation. This type
of activity is deplorable and indefensible.
We must also
consider that the sponsors of pro-fluoridation
opinion polls use hypothesis to obtain support. By
structuring questions that induced a positive
response, it is possible to get 'approval' for
fluoridation - if only by proxy. Think about it,
it's easy to see how even the most moderate
confidence trickster could get you to say yes to a
proposition, a proposition which you may say no to
in an environment where you have more of the facts
at your disposal.
There are a number
of ways you can achieve these goals. The first is
the 'hit-and-run' tactic of a 'street poll'. By
approaching people on the street you can catch them
off-guard. The second is by visiting people in their
own homes. In this scenario, the opinion poll
respondent has more time to consider their reply.
However, in this this type of situation,
'conditioning' is sometimes required to obtain the
desired result.
In either
situation, you need an organisation that appears to
be independent but which is more than capable of
meeting their contractor's needs.

1992 UK Poll: "79%
NOW IN FAVOUR" |

Hardly surprising
considering the question is loaded. "Do you
think fluoride should be added to water if it
can reduce tooth decay?" A positive association
with fluoride produces a positive answer. |
Referenda
This is why this
type of question is favoured above a properly held
referendum where the respondent is allowed to make
an informed choice. Referenda show that on the
majority of occasions, people tend to reject the
idea of water fluoridation.
In 1985, during the
passage of the Water Fluoridation Bill, former
Health Minister Ken Clarke stated that he was not in
favour of a referendum to determine public opinion
on fluoridation. He alluded to the fact that because
the population in general did not understand the
intricacies of fluoridation that it was pointless
holding a referenda.
What he really
implied was that we should not be trusted with a
vote, despite it being an important aspect of
democracy. It's a bit like an incumbent but very
unpopular Government prior to a General Election
saying that there will be no Election because most
of the electorate aren't wise enough to cast a vote
in their favour.
The final example
which highlights the pro-fluoride lobby's dislike of
referenda is a story which appeared in the
Fluoride Report in April 1994.
In 1990, a health
officer of the state of Florida gave a blueprint for
introducing fluoridation to an official of St
Petersburg. He was told one of the most important
tactics to consider is:
"Avoid a
referendum. The statistics are 3 out of 4
fluoridation referenda fail."
(From letter
written by Susan Allen, RDH, BS, Fluoridation
Co-ordinator, Public Health Dental Program, State
of Florida Department of Health & Rehabilitive
Services to H. Tolson, May 7, 1990).
Perhaps the advice
should have been to avoid a referenda when it
cannot be rigged in your favour!
