12th European Skeptics Congress.
Pseudoscience, Alternative Medicine And The Media
Brussels, Belgium, October 13-16, 2005
by Dr Richard Hardwick, Brussels
Contents
The 12th European Skeptical Congress was billed as "an exceptional
occasion, right in the middle of the capital of Europe, to share
experiences and build a platform of rationality. Skeptics, scientists
and journalists from all over Europe will gather to explore the field
of knowledge and knowledge communication". And yes, it is bizarre
what some people believe. But there you go, there's nowt so queer as
folk
(UK informal saying; said to emphasize that people sometimes behave in a very
strange way),
one man's meat is another man's poison, it would be a dull
world if we all thought the same, and there's an end on it.
Except, except, that some people's bizarre beliefs seem to get up
other people's noses. So much so that there are even a few bizarre
academics who spend their time and tax payers' (?) money enquiring
why other bizarre people adopt bizarre beliefs. Does it matter? Is it
worth starting to save up for the next European Skeptics Congress??
Well yes, after three enjoyable days at the 2005 Congress, I think
all this does matter, and I think it probably will be worth going to
the next European Skeptics Congress (Ireland, 2007) - provided, that
is, that the European Skeptics promise to start taking their own
medicine. What is sauce for the goose is sauce for the gander, or
ce qui est bon pour l'un l'est pour l'autre, as we Europeans
say.
I should note straight off that the 2005 Congress was well organized,
with a (mostly) excellent set of contributions, a nice venue, good
logistics support, and even a much appreciated book-stall. There is
also a first class
website for the Congress . It's a pity that the programme had nothing on Skepticism
and the EU, but perhaps that's a subject for another time.
I suppose that most readers of this page will want to read about the final
event on the programme. I think the Congress organisers foresaw this as a
barbecue-with-fireworks, where Rupert Sheldrake would be spit-roasted by the
assembled company, led by Dr. Jan Willem Nienhuys (ex University of
Eindhoven), with Prof Johan Braeckman (University of Ghent) to see fair play.
It didn't quite turn out like that.
But before talking about the Sheldrake event I must give an overview of the
Congress as a whole. You can find summaries of all the talks on
the Congress web site (see end note 1). I have also put links
to the Congress web site's nice biographies of the speakers into this text.
First then there were reports from the skeptics' front line.
Herbal fraud in the Netherlands: Libidfit (Marie Prins,
NL) related the tale of a "400-year old recipe used by the Royal
Court" that is undoubtedly efficacious for flaccid Royal males, but
only, it turns out, thanks to some undeclared, and much less than 400
year old, additional molecules of Viagra.
From the Sokal affair to the Teissier affair (Professor Jean
Bricmont, University of Louvain, BE) ran from post modernist fun and
games - which are still not over (see end note 2) - to the more
recent affair of François Mitterrand's astrologer Dr Elizabeth
Teissier whose doctorate was awarded her by the Sorbonne, no
less.
From Africa, Professor Fadel Niang (Ecole Supérieure Polytechnique -
Senegal) had an excellent presentation on Pseudosciences,
libertés médiatiques et esprit critique en Afrique de l'Ouest
(Pseudoscience, exaggerations in the media, and the critical approach in West Africa).
Finally back in Europe and
On the policy of some Dutch
medical-scientific societies towards their members, practicing
alternative medicine: reproachable negligence by Dr Cees
Renckens (Westfries Gasthuis - NL), a skeptical doctor at the front
line, who described how he had detected questionable practices of
certain Dutch internists, neurologists, clinical chemists and dental
surgeons; and blown the whistle. The results were somewhat variable.
Overall it seems to me that skeptical detecting is a good sport, but
that the technology has not advanced much since the time of I.J Good
(see end note 3).
Then there were presentations by academics; by those who are teaching
their students how to think skeptically - Richard Monvoisin (EDISCE, FR)
Forewarned is forearmed - How to use examples of pseudoscientific
gaps and insidious philosophical trends in science magazines to teach
critical thinking and by those who do research, trying to
understand whats going on in the minds of uncritical believers;
James E. Alcock (York University - Canada)
The appeal of
alternative medicine;
Barry Beyerstein (Simon Fraser University
- Canada)
Errors of perception and reasoning that make bogus
therapies seem to work;
Michael Heap (University of Sheffield -
UK) (no biography found on the Congress website) Let's wave goodbye to the unconscious mind;
Christopher French (Goldsmiths College London- UK)
The "Haunt" Project: Can we build a "haunted" room?
The teaching approach seemed to me very Cartesian, first teaching a
typology of errors, then applying it to dismember someone else's
straw man. I would prefer to teach critical thinking via a bit of
hands on enquiry (lets try to walk on water, on fire), or at least
via Socratic dialogue, in the fashion of Oxbridge supervisions. But
perhaps that's not judged cost-effective, in these cash-strapped
times.
Among the academic researchers, I was heartened to listen to
some good plain common sense; for example
- Alcock; … the appeal of alternative medicine is not dissimilar to the
appeal of evidence-based medicine as it was traditionally provided by family
physicians in the past … There is much more to medicine than medicine:
- Beyerstein … the majority of those who sell bogus products, however,
are not deliberate frauds, but "sincere but self-deluded.":
- Heap …If activities cause us fear, anxiety, guilt, anger and so on we
often avoid doing them; this avoidance can be habitual and we may not be
fully aware that we are doing this. … the therapist helps the person to
confront the things that he or she is avoiding through anxiety and so on, and
to be able to deal appropriately with them
But the Congress flier says … it will be necessary to understand
what's making them (bogus therapies and pseudoscientific stories) so
attractive and why -- among other things -- politicians so often lend
them a helping hand.
I do not judge that such understanding was demonstrated, at least not
in the sense of being able to predict what strange things people
will believe next. Perhaps, after all, its enough to conclude that
there's nowt so queer as folk.
The speakers certainly did demonstrate that some in our society are
vulnerable to poppycock dressed up as expertise, and that we cant
always rely on our official gatekeepers to filter it out. However,
see end note 4 for a case of official gatekeepers
who have done their job. Perhaps the 2007 Congress should try to draw
up a gate-keepers' score-sheet; goals for and goals
against.
Its not easy, though. Knowing nothing about the affair of
The
WHO and homeopathy, I was carried away by Professor Willem Betz
(VUB Brussels BE) "…Organisations that sell or promote un-scientific
or anti-scientific medicine have infiltrated the decision making
levels of the WHO. The latest scandal was the secret attempt to
prepare a dishonest pro-homeopathy propaganda pamphlet for
publishing. Is was only thinly disguised as a scientific study …".
Strong sceptical stuff.
But after the Congress I cross checked on
WHO's website… and found this:
New WHO guidelines to promote proper use of alternative medicines
Adverse drug reactions to alternative medicines have more than doubled in
three years
"WHO supports traditional and
alternative medicines when these have demonstrated benefits for the
patient and minimal risks", said Dr LEE Jong-wook, Director-General of
WHO. "But as more people use these medicines, governments should have
the tools to ensure all stakeholders have the best information about
their benefits and their risks".
Doesn't seem dishonest to me. So is Professor Betz over-stating
his case (no-score draw)? Or did WHO secretly beat a retreat (Betz 1, WHO
nil)? Until bureaucracies publish a mea culpa, keeping a skeptical score is
going to be difficult.
For levering stories out of laboratories, or out of bureaucracies,
investigative journalists are are the full-time professionals. It was
therefore very good to have an analysis from a watcher of the media,
Frits Van Dam (Universiteit van Amsterdam)
Fluctuations in the
use of alternative cancer therapies through the years, the influence
of mass media. And it was even better to listen to real working
journalists; Dirk Volckaerts (BE)
On Ethics and Credibility in
Newspaper Journalism; Luis Alfonso Gámez (ES)
Paranormal in
the Press. A skeptical point of information for millions of
readers, and Hans van Maanen (NL)
Sex and science.
All the journalists underlined the importance, and the efficiency, of
journalistic ethics, and I don't think that their stories from the
newsrooms supported the assertions in the Congress flier that … All
too many bogus therapies and pseudoscientific stories get unbridled
attention … Accuracy and truthfulness are all too often sacrificed
on the altar of the news breaking scoop…. I suppose it depends on
what is meant by "too many", "too often".
And here the problem is, as Professor Jean-Paul Van Bendegem (VUB
Brussels) showed in his talk
2 + 2 = 4, or whatever you
want, "In a sense you have to be a bit of a mathematician to get
the mathematical "feeling" (for what is totally convincing
evidence)". The size of that "bit" is non-negligeable. I speak with
passion, having wrestled for the last 18 months with the felicitious,
indispensable, but for me as non-mathematician, impenetrable
Jaynes .
Which brings me to
Paranormal beliefs: the psychological approach by the unfortunate Dr
Jean-Michel Abrassart (Centre for psychology of religion Louvain-la-Neuve
BE). In response to a (my) question about his analyses of the relationship
between predispositional and situational factors x,and belief in
paranormal phenomena y, Dr Abrassart replied that he could not say
whether the values of r which his computer had calculated for him
were correlation coefficients, or Spearman's rank coefficients. At this
point I would have hoped that the EuroSkeptics would have howled for blood,
or thrown paper darts, or at least chanted the Belgian Skeptics' mantra (end note 6). But the room fell silent, and no-one followed up.
The Congress flier asks "How good is your critical remark when the
pseudoscientific claim gets all the attention?" To my mind,
critiquer les autres. c'est s'exposer à la
critique (people who live in glasshouses are best advised not
to throw stones). But from this experience I conclude that Skeptics are not
too good at autocriticism
So finally to the end of the Congress and the Sheldrake versus Nienhuys
spit-roast. Dr Sheldrake was on first. Sheldrake of course is not a
University professor. On the contrary, he comes well prepared, and he speaks
fluently and clearly, as if he really wants to communicate. He marshals his
arguments with precision, he provides (so far as I can judge) evidence for
his statements, and he brings his nul hypotheses out into the open, ready to
be shot down by the force of disproof.
In my judgement, Nienhuys' counterattack failed. Sheldrake mostly
discussed his work on animal behaviour. His hypotheses were there for the
taking. I cite just one example, on the apparently coordinated movements of
flocking birds. Sheldrake claimed that this coordination cannot be explained
by individual reactions, because eye-brain-muscular responses are too slow.
A quick check with Google after the congress gets me a paper in Nature in
1984 that seems to agree, and to provide an alternative, the Chorus Line
Hypothesis of Manoeuvre Coordination in Avian Flocks (end note
7), which does not involve morphic resonance.
This is an alternative nul hypothesis that is testable. I don't know
whether it has been tested or not; but it should be easy to find out
see note added in proof (end note 8).
And I guess that there must be more, probably one for each of
Sheldrake's hypotheses. But it seems Dr Nienhuys had not done his
homework. He did not have any data or analyses to hand, and his
attack fizzled out.
So in the questionnaire that was (commendably) distributed to the
participants for filling in afterwards, I scored the encounter, not
"game set and match to Sheldrake", but at least Sheldrake 40,
Nienhuys love. A small cluster gathered around Sheldrake at the end
of the Congress. They seemed to be talking with him, rather than
pumelling him to the ground, so perhaps they agreed with me.
The opportunity of a real skeptical public test of opposing
hypotheses has been missed this time. Perhaps for Ireland in 2007?

- The chorus line hypothesis - note added in proof.
Dr Sheldrake tells me
that indeed
"I discuss Potts' chorus line hypothesis in my book THE PRESENCE OF THE
PAST, and show it is not a real alternative - Potts, who invoked it,
proposed that birds responded to a maneuver wave in the flock, and these
are now modelled on computers by field models. So if your research had
gone further, it would have led back to the field idea.
And if Nienhuys had
brought up the point you made, I would have replied by pointing this out.
So although your point was that he was poorly prepared is certainly true,
this is not a particularly fair example."
