The
Wichita Poll [30th January 2001]
A second opinion
poll conducted in the USA between January 2nd -
15th, 2001, gave a clearer demonstration of how
biased such a survey could be.
The Wichita Eagle
(Kansas) published the following headline on the
30th January, 2001;-
"Poll: Wichitans
express support for fluoridation". What is perhaps
not readily visible to the reader is that the poll
was conducted by the newspaper's own "Research
Centre."
There is nothing
wrong with a newspaper publishing the outcome of
it's own opinion poll but when such a poll was
contrived to influence the respondent into giving a
reply which favours fluoridation, the issue takes on
a new perspective.
A total of 20
questions were asked in the 'Wichita poll', some of
which are not relevant to this story. Questions 1
and 2 asked about the respondents residency.
Questions 11 to 20 asked about dental insurance and
social practices. This left questions 3 to 10 to
focus on fluoridation.
Question 3
was a 'primer' and made a positive assertion about
fluoride;-
"Fluoride is a
naturally occurring element that prevents tooth
decay. Some communities add fluoride to the
public's water supply to help improve resident's
dental health. How familiar are you with the use
of fluoride to prevent tooth decay?"
Three times an
association between fluoride and improved dental
health was made. However, no mention was made of the
fact that fluoride added to water can contain many
impurities such as arsenic, cadmium, mercury, lead,
cyanide, etc. The question also failed to present
any credible evidence that fluoride in water
prevents tooth decay. There is no doubt that this
question introduced an element of conditioning.
Question 4
asked where the respondent obtained their
information about fluoride.
Question 5
then asked if the respondent was in favour of or
opposed to adding fluoride to Wichita's water. This
question was supplemented and the respondent had to
explain their point of view.
Questions 6 and
7 made further numerous positive assertions
about fluoridation. This is an attempt to reinforce
question 3 and to sway the respondents who are
opposed to fluoridation ( possibly with a view to
influencing the respondents views in a future poll
).
Question 8
was a repeat of question 4 except the respondent was
asked which source they considered the best for
information about fluoridating Wichita's water. This
again is a clever ploy to dissuade opponents who may
not have based their views on 'sanitised'
information sources.
Question 9
asked the respondent who was best placed to decide
on a plan to introduce fluoridation, a Government
official, the voter, or 'do not know'.
Question 10
asked how the respondent would vote if given the
opportunity.
