Informationsnetzwerk Homöopathie


Informationsnetzwerk Homöopathie (Information Network Homeopathy, INH) is a working group of the German skeptics organization GWUP and is currently the most popular group of critics of homeopathy in the German speaking countries. Coverage in the leading media is excellent, and we think we contributed a lot to the increasing discussion on homeopathy - and the critical position some politicians assumed in recent time.

As such INH is the most successful venture of GWUP over the past years. This presentation is to give some history of INH from its beginning in 2016. I will present our targets and our strategies how we set about to reach them. What websites we run, how we handle social media, what projects did we realize, who are the key persons and the key success factors - and how the winds have turned against homeopathy in its last European stronghold.

How skepticism helped me become pro-nuclear


In a world where strong positions are held, substantiation is key. As a skeptic I take tentative positions based on evidence and evidence alone. Both in the Climate Change discussion as the discussion surrounding Nuclear Energy many claims are made. But whose claims are true, and whose claims are false. After years of following and partaking in debates I’ve concluded that the evidence in support for climate change is overwhelming; If Climate Change is true the corollary questions is: “What should we do about it?” and that’s where my adventure truly began. Can we power the world using wind and solar? Or do we need extra technologies to solve the climate change conundrum?

Con men in the art world


"Con men" are people with a special talent to gain other people's trust and confidence, in order to trick them into something, deceive them, steal from them or abuse them in some other way. A con men often pretends to be someone he is not, e.g. a pilot, a surgeon or an academic. More often than not, they'll get away with it. Most people,  no matter what their level of education or intelligence might be, seem to be vulnerable for the way experienced con men operate. In this lecture, we explore the modus operandi of con men specialized in creating and selling fake art. Studying the way they manage to fool people, is a very interesting case study in critical thinking and skeptical investigation.

Near-death experiences: actual considerations


The notion that death represents a passing to an afterlife, where we are reunited with loved ones and live eternally in a utopian paradise, is common in the anecdotal reports of people who have encountered a “Near-Death Experience” (NDE). These experiences are usually portrayed as being extremely pleasant including features such as a feeling of peacefulness, the vision of a dark tunnel leading to a brilliant light, the sensation of leaving the body, or the experience of a life-review. NDEs are increasingly being reported as a clearly identifiable physiological and psychological reality of clinical and scientific significance. The definition and causes of the phenomenon as well as the identification of NDE experiencers is still a matter of debate. The phenomenon has been thoroughly portrayed by the media but the science of NDEs is rather recent and still lacking of rigorous experimental data and reproducible controlled experiments. It seems that the most appropriate theories to explain the phenomenon tend to integrate both psychological and neurobiological mechanisms. The paradoxical dissociation between the richness and intensity of the memory, probably occurring during a moment of brain dysfunction, offers a unique opportunity to better understand the neural correlates of consciousness.

The battle against SCAM. Are we winning?


What do governments and health organisations like WHO do against quackery?

Given the common use of quackery in virtually all countries, one would expect that governments and international organisations like the WHO would have developed effective strategies to limit its prevalence and minimise the harm quackery unquestionably does. Sadly, very few such initiatives seem to exist. Those organisations that actively fight quackery tend not to be run by governments but rely on private, altruistic initiatives. The WHO even has been responsible for several actions that arguably are not fighting but promoting quackery. This lecture will review several recent examples. It is concluded that governments and the WHO have, in the past, turned a blind eye to quackery. In the interest of public health, this situation has to change.

Is it still possible to rationally address modern agriculture ?


Due to some issues such as mad cow disease, water pollution, food safety, a lot of technical or scientific discussions regarding modern agriculture, such as about GMOs, neonicotinoids or glyphosate, were held in the media, political bodies and the public . These discussions very often forget scientific evidence, to focus on a dogmatic point of view regarding safety, environment or quality of life. All these arguments to justify a return to the past, also forget how old ways of farming were difficult and unsafe.

My talk will more or less address the following points:

  • 3 decades which changed public perception of agriculture

  • Idealized agriculture vs real agriculture

  • Rejected innovation in agriculture: science and dogmatism

  • Some proposals to reconcile modern agriculture and society’s needs

Biographical information

Comedian-Mentalist Gili (aka Lieven Gheysen) launched his carreer as Belgium’s best known magician and mentalist with a theater show “Iedereen Paranormaal” (Everybody Paranormal), as a reaction to the media-tsunami about the paranormal TV show “Het Zesde Zintuig” (the sixth sense). His next show "CTRL: Alles onder controle" (CTRL: Everything under control) sent whole audiences home in confusion, doubting their senses.

Gili uses his five senses so well that he appears to have a sixth sense: this has become his trademark, by which he makes fun of presumed psychics and clairvoyants.

The Netherlands and France as well fell for his charms, in talk shows and on stage. This spring he presented shows in the famous Apollo theater in Paris, and for one month this summer he was a guest at the theater festival of Avignon.

Science and decision: towards restoring scientific integrity in policy making


50 years ago (November 1968) a journalist, Michel Rouzé, founded the French Agency for Scientific Information and began with publishing its notebooks.

Three decades later (1999) the magazine Science & pseudo-sciences was followed by some hundreds of subscribers and decision was taken, under the impulsion of the astrophysicist and member of the French Academy of Science Jean-Claude Pecker, to impulse the association towards a new dimension.

Today (2019), with roughly 1500 association members, 3000 magazine subscribers, and 25,000 printed copies of the magazine disseminated by the press networks, the Association Française pour l’Information Scientifique (AFIS) became the biggest organization in France of the scientific rationalism.

Scientific rationalism can be synthetized with two assertions. (1) There is no better method than the scientific method to apprehend reality with reliability. (2) Reason is the best tool that man has at his disposal to pose with relevance and successfully solve the problems that arise for him, individually and collectively.

In addition to the traditional matters of a skeptical organization (pseudo-therapies, astrology and other old or new unfounded beliefs, paranormal pretentions, …) AFIS and Science & pseudo-sciences work also to enlighten the advancement of science and the interface between technologies and society.

The context has moved since the end of the 60’s. At the beginning of the 21st century, the controversies that have developed at the interface between science, technology and society have become much more important in everyone's preoccupations.

The classical process should be well known. When it is relevant to get a political decision, the decider ask scientists to drive a fact based instruction and to report. Then, the decider takes in account these elements and add the other necessary dimensions (economics, ethics, politics, social acceptance, etc.) : Science says (what is true, what is false, what is uncertain) but does not dictate (what to do or not to do).

Even if science can describe us as well as possible the reality; even if it can anticipate as plausibly as we want on the possible consequences of our action or inaction; the need or the desirability of an action is not and cannot be a scientific deduction.

Nevertheless, it happens regularly on these controversial issues (GMOs, ionizing radiation, electromagnetic waves, new breeding technologies, plant protection, vaccination, public health, etc.) that a significant fraction of the opinion and of the policymakers, remains hermetic to the conclusions of scientific expertise.

Descent into one’s own illusion


The astrological claims of French psychologist Michel Gauquelin date from 1955 onwards. One of his claims was that sports champions are born slight more often when Mars rises than chance would predict. This claim occupied skeptics between roughly 1967 and 1997. It seems to be an illusion, partially created by the desire to get as many as possible reliable data.

Jan Willem Nienhuys (1942) studied mathematics in the Netherlands and the USA. He teached mathematics at universities in Taiwan and, from 1973 onwards, at the Eindhoven University of Technology in the Netherlands. He is a free lance translator of popular science books, and writes frequently on subjects like pseudo-science and quackery.

When using magicians to study how paranormal beliefs come about


Humans belief, in many things. Popular are supernatural beliefs, hotly debated by believers and skeptics alike. Psychologists reported on various variables that correlate with such beliefs (e.g., appreciation of chance, more open to experiences). Yet, these latter studies are correlational unable to convey whether existing beliefs predict the appreciation of chance  (e.g., becoming more associative), or whether being more associative predicts the formation or reinforcement of paranormal beliefs. Over the last years, we performed several series in which we investigated the causality of belief change / reinforcement. In these studies, a magician performed a central event (e.g., a medium talking to a dead person, pseudo-scientific mind reading). Therefore, we could compare psychological variables we assessed before and after the event (tackling causality). Also, we could assess which pre-existing variables (e.g., paranormal beliefs, associative processing) predicted paranormal interpretations. Performing all studies in the classroom, we observed an overall high willingness to accept what the persons had just seen. In one study, around 65% considered that they had witnessed a genuine psychic event. Higher paranormal beliefs and affective reactions predicted a higher endorsement of a psychic explanation. Seeing how easily people are convinced by what they see, we are now starting to “debunking” participants in order to test which pre-performance information we have to provide to render participants more critical as to what is presented to their eyes. We assume that once the magician spells the beans, the belief in what one sees should be gone.

Today, her research focuses on two major domains (human belief, colour and affect). In the domain of human belief, she is studying the cognitive, neuropsychological, and personality correlates of magical and paranormal beliefs for many years. She performs studies in the laboratory aimed at determining the mechanisms that can explain, at least partially, the extent in which people vary in their beliefs. Over the last years, she developed a comprehensive research program with Dr. Gustav Kuhn (London) using magic. They are designing research paradigms that help us understand the causal mechanisms of human belief formation. Part of these studies will be presented here.

Energy and decarbonisation


Critical Thinking: Taking Green Energy Goals Seriously

 Scientific skepticism has an important role not only in recognition of real and pressing environmental threats, but also in assessing the best tools for tackling them. We must ensure that our environmentally motivated efforts are not merely symbolic, but that they translate to real and concrete effects in conserving nature and mitigating climate change.

The sincere wish to do good combined with a failure to fully assess the premises of our thinking in an evidence-based way, have lead to many institutional and popular sentiments that are seemingly environmental, but which end up interfering with environmental goals through strong ideological opposition to important options, like is the case with nuclear power, and easy acceptance of options that feel ‘greener,’ but where a skeptical assessment quickly reveals severe drawbacks, like with suggestions to dramatically ramp-up biomass production, or to build massive redundancies into land and resource-intensive solar, wind, and battery-installations.

All environmental harm should matter, and we should strive to minimise it over the board. The impacts of land use, resource use, and emissions all need to be taken into consideration – a small decrease in one area does not get us far if it drastically increases problems in other important aspects. There are few technologies where broad scientific assessments of such benefits and drawbacks are so much at odds with popular and political sentiments than it is with nuclear energy. If we do take the green energy goals seriously, however, this is highly concerning, because as the recent International Energy Agency reports underlines: nuclear can make a significant contribution to achieving sustainable energy goals and enhancing energy security.

Our energy policies are in dire need of scientific skepticism. We should look to countries that have come furthest with decarbonisation of their grids, learn from them, and look further still: we need to put the onus on how low-carbon energy can help with deep decarbonisation of our societies not only with regards to electricity, but also the sectors of heating and transportation. We need rapid advances in serious, science-based energy policy in order to conserve nature and protect human societies from the gravest effects of climate change.

Vitamin B12 clinics: An example of a hype that results in clinics with quackery


In the late 1950s, Sir Bradford Hill, a British public health scientist defined nine criteria for causality in medicine, of which ‘experimental proof’ and ‘biological plausibility’ are two main criteria that distinguish straightforward quackery from evidence-based medicine. In recent years, some shrewd quacks have found a niche by prescribing drugs or technology which are being used in regular medicine under strict conditions, but which are now also prescribed beyond those strict conditions for which they have not been tested and not approved.

Vitamin B12 is such a drug: vitamin B12 or cobolamine is required for many metabolic processes, amongst others for the formation of red blood cells and nerves. Animal products (milk, eggs, meat) are rich natural sources of vit. B12. There are a few groups at risk for development of genuine Vit. B12 deficiency: Vit B12 is absorbed in the stomach, and patients who had a gastric bypass or removal of the stomach, who have atrophia of the gastric epithelium (pernicious anaemia) or who are severely malnourished or who follow a strict vegan diet may develop deficiency of vit. B12 with nervous problems and anaemia. These cases can easily be diagnosed by any family physician, -all have anaemia and a specific medical history-, and are for a few euros cured by vit. B12.

However, in recent years, an increasing number of persons without anaemia but with none-specific symptoms of chronic fatigue or nervous irritability is tested for serum vit. B12 levels (and related substrates methyl-malonic-acid and homocysteine); those with marginal low levels are then diagnosed with quasi-vitamin B12 deficiency and are recommended chronical parenteral vit. B12 in commercial vit. B12 clinics. Except for inciodental case studies, there is however not a single cohort  or case-control study in persons without anaemia or known medical cause of vit. B12, that has shown a cause-effect relation between marginal low vit B12 level (or low methylmalonic acid level) and symptoms, and the few randomized studies did not show benefit of more than physiological doses of vit. B12. Since many of the symptoms in patients with marginally low vit B12 are qualitative (fatigue, irritability, non-objective visual disturbances, lack of appetite, bad mood), a double-blind randomized trial is needed to test the efficacy of vit. B12 injections. Such a study has never been done and physicians of commercial Vitamin B12 Deficiency organizations have in the last 20 years not been successful to initiate such a study. For the time being: Parenteral Vit B12 treatment of marginally low Vit B12 without anaemia or known cause is pseudo-scientific abusive medical practice.
