The public feels the media were too quick to report
maverickclaims
The media love a maverick. That's one reason why a figure suchas
Dr Andrew Wakefield, who challenged established thinkingover the
measles, mumps, and rubella (MMR) vaccine, has receivedso much
coverage in the British press. But although some newspapershave
presented Wakefield as a popular hero, fighting scientific
officialdom on behalf of parents worried about
autism, nearlyhalf of the public believes that
journalists should have subjectedhis claims to more scrutiny before
reporting them.
Wakefield: not "comprehensively"
challenged

A study of what and how people learn about science from themedia
discovered that 48% of the public felt that when scientistsgo
against the grain, as Wakefield did in suggesting a linkbetween MMR
and autism, the media should wait
until other studiesconfirm those findings before covering them.
Thirty-four percent of the survey sample of more than 1000 people
thought that the media should give such scientists prominent coverage
and 18% expressed no opinion.
The public's reticence might seem "odd," particularly sinceMMR
"does not involve issues of privacy, and since such workmay already
be in the public domain through publication inreputable journals,"
say the researchers from Cardiff UniversitySchool of Journalism.
"But it speaks to the degree to whichmany people feel the need for
expert guidance on scientificissues."
The researchers analysed the way in which science and science
related issues were reported on television news, radio news,and in
the press during seven and a half months in 2002. Theyalso used two
nationwide surveys (using representative samplesof more than 1000
people), carried out in April and October2002, which tracked the
public's knowledge, opinion, and understandingof science related
issues reported in the media. The focusof their attention was on
climate change, the MMR controversy,and cloning and genetic medical
research.
Their report, Towards a Better Map: Science, the Public andthe
Media, published last month, found that what people knewusually
corresponded with those aspects of a story that receivedmost
persistent coverage. "The details or subtleties of mediacoverage
are, in this respect, much less important than thegeneral themes of
that coverage, in which certain ideas arerepeated and associated
with one another," says the report.MMR and
autism is one example of such repetition and
association."While this does mean some information is communicated
effectivelyto most people, it can also result in widespread
misunderstandingevenif the reporting itself is generally accurate."
In the case of MMR and autism,
people were also misled by thejournalistic quest for balance in
reporting. The researcherssay, "We discovered that the coverage was
unintentionally misleadingin creating the impression that the
evidence for the link wasas substantial as the evidence against it."
This is a findingthat also emerged in preliminary results released
last September(BMJ 2002;325: 603[Free Full Text]). Only 30%
in the April survey and 23%in the October survey were aware that the
bulk of the evidencefavoured supporters of the MMR vaccine.
The researchers found that Wakefield's claimsof a speculative
link between the MMR vaccine and autism,
"with questionablescientific data to support it"were not
"comprehensivelyor systematically challenged in media coverage."
Instead, themedia leapt to the speculative link, and then, because
therisks of non-vaccination were fairly clear, the idea of offeringthree single jabs gained a great deal of currency. This put
government and scientists supporting MMR on the defensive, and
pitched them against the notion of parental choice. "This createda
serious difficulty for the scientists and health professionals,who
are only able to propose dry generalisations against themore emotive
and sympathetic figures of parents concerned forthe welfare of their
children," says the report.
The researchers say that "while Wakefield's claims are of legitimatepublic interest, our report does give credence to the viewthat
research questioning the safety of something that is widelyused
should be approached with caution, both by scientistspublishing that
research and journalists covering it." Theyadd, "This is especially
the case if any decline in publicconfidence has negative
consequences for public health."
This does pose a difficulty for journalists, however, and for
non-specialist reporters in particular: how to distinguishan MMR
from a thalidomide. Sometimes, it seems, the publicwants them to
raise the alarm and sometimes it doesn't. Andsometimes there is
simply just no alarm for them to raise.
