A cult can be defined not just in a religious context, but also as a” usually nonscientific method or regimen claimed by its originator to have exclusive or exceptional power in curing a particular disease.” After ~20 years of researching this area, I have come to suspect that much of alternative medicine resembles a cult – a bold statement, so I better explain.
One characteristic of a cult is the unquestioning commitment of its members to the bizarre ideas of their iconic leader. This, I think, chimes with several forms alternative medicine. Homeopaths, for instance, very rarely question the implausible doctrines of Hahnemann who, to them, is some sort of a semi-god. Similarly, few chiropractors doubt even the most ridiculous assumptions of their founding father, D D Palmer who, despite of having been a somewhat pathetic figure, is uncritically worshipped. By definition, a cult-leader is idealised and thus not accountable to anyone; he (yes, it is almost invariably a male person) cannot be proven wrong by logic arguments nor by scientific facts. He is quite simply immune to any form of scrutiny. Those who dare to disagree with his dogma are expelled, punished, defamed or all of the above.
Cults tend to brain-wash their members into unconditional submission and belief. Likewise, fanatics of alternative medicine tend to be brain-washed, i.e. systematically misinformed to the extend that reality becomes invisible. They unquestioningly believe in what they have been told, in what they have read in their cult-texts, and in what they have learnt from their cult-peers. The effects of this phenomenon can be dramatic: the powers of discrimination of the cult-member are reduced, critical questions are discouraged, and no amount of evidence can dissuade the cult-member from abandoning even the most indefensible concepts. Internal criticism is thus by definition non-existent.
Like religious cults, many forms of alternative medicine promote an elitist concept. Cult-members become convinced of their superiority, based not on rational considerations but on irrational beliefs. This phenomenon has a range of consequences. It leads to the isolation of the cult-member from the rest of the world. By definition, critics of the cult do not belong to the elite; they are viewed as not being able to comprehend the subtleties of the issues at hand and are thus ignored or not taken seriously. For cult-members, external criticism is thus non-existent or invalid.
Cult-members tend to be on a mission, and so are many enthusiasts of alternative medicine. They use any conceivable means to recruit new converts. For instance, they try to convince family, friends and acquaintances of their belief in their particular alternative therapy at every conceivable occasion. They also try to operate on a political level to popularize their cult. They cherry pick data, often argue emotionally rather than rationally, and ignore all arguments which contradict their belief system.
Cult-members, in their isolation from society, tend to be assume that there is little worthy of their consideration outside the cult. Similarly, enthusiasts of alternative medicine tend to think that their treatment is the only true method of healing. Therapies, concepts and facts which are not cult-approved are systematically defamed. An example is the notion of BIG PHARMA which is employed regularly in alternative medicine. No reasonable person assumes that the pharmaceutical industry smells of roses. However, the exaggerated and systematic denunciation of this industry and its achievements is a characteristic of virtually all branches of alternative medicine. Such behaviour usually tells us more about the accuser than the accused.
There are many other parallels between a cult and alternative medicine, I am sure. In my view, the most striking one must be the fact that any spark of cognitive dissonance in the cult-victim is being extinguished by highly effective and incessant flow of misinformation which often amounts to a form of brain-washing.
The main aim of our systematic review was to estimate the prevalence of use of alternative medicine (AM) in the UK. Five databases were searched for peer-reviewed surveys published between 1 January 2000 and 7 October 2011. In addition, relevant book chapters and files from our own departmental records were searched by hand. Eighty-nine surveys were included, with a total of 97,222 participants. Surely, fact that this large amount of UK surveys had emerged in only about one decade, speaks for itself.
Most studies turned out to be of poor methodological quality. Across all surveys, the average one-year prevalence of AM-use was 41.1%, and the average lifetime prevalence was 51.8%. However, many of these investigations were flimsy. According to methodologically sound surveys, the equivalent rates were 26.3% and 44%, respectively. In surveys with response rates >70%, the average one-year prevalence was nearly threefold lower than in surveys with response rates below 50%. Herbal medicine was the most popular CAM, followed by homeopathy, aromatherapy, massage and reflexology.
To the best of my knowledge, this is the first time that four crucial points about such surveys have been clearly documented:
1) The amount of surveys in AM is staggering.
2) They contribute very little worthwhile knowledge and mostly seem to be exercises in AM-promotion.
3) Their methodological quality is usually low.
4) The poor quality surveys systematically over-estimate the prevalence of AM-use.
I think it is time that AM investigators focus on real research answering important questions which advance out knowledge, that AM-journal editors stop publishing meaningless nonsense, and that decision-makers understand the difference between promotion dressed up as science and real research.
Even after all these years of full-time research into alternative medicine and uncounted exchanges with enthusiasts involved in this sector, I find the logic that is often applied in this field bewildering and the unproductiveness of the dialogue disturbing.
To explain what I mean, it be might best to publish a (fictitious, perhaps slightly exaggerated) debate between a critical thinker or scientist (S) and an uncritical proponent (P) of one particular form of alternative medicine.
P: Did you see this interesting study demonstrating that treatment X is now widely accepted, even by highly critical GPs at the cutting edge of health care?
S: This was a survey, not a ‘study’, and I never found the average GP “highly critical”. Surveys of this nature are fairly useless and they “demonstrate” nothing of real value.
P: Whatever, but it showed that GPs accept treatment X. This can only mean that they realise how safe and effective it is.
S: Not necessarily, GPs might just give in to consumer demand, or the sample was cleverly selected, or the question was asked in a leading manner, etc.
P: Hardly, because there is plenty of good evidence for treatment X.
S: Really? Show me.
P: There is this study here which proves that treatment X works and is risk-free.
S: The study was far too small to demonstrate safety, and it is wide open to multiple sources of bias. Therefore it does not conclusively show efficacy either.
P: You just say this because you don’t like its result! You have a closed mind!
In any case, it was merely an example! There are plenty more positive studies; do your research properly before you talk such nonsense.
S: I did do some research and I found a recent, high quality systematic review that arrived at a negative conclusion about the value of treatment X.
P: That review was done by sceptics who clearly have an axe to grind. It is based on studies which do not account for the intrinsic subtleties of treatment X. Therefore they are unfair tests of treatment X. These trials don’t really count at all. Every insider knows that! The fact that you cite it merely confirms that you do not understand what you are talking about.
S: It seems to me, that you like scientific evidence only when it confirms your belief. This, I am afraid, is what quacks tend to do!
P: I strongly object to being insulted in this way.
S: I did not insult you, I merely made a statement of fact.
P: If you like facts, you have to see that one needs to have sufficient expertise in treatment X in order to apply it properly and effectively. This important fact is neglected in all of those trials that report negative results; and that’s why they are negative. Simple! I really don’t understand why you are too stupid to understand this. Such studies do not show that treatment X is ineffective, but they demonstrate that the investigators were incompetent or hired with the remit to discredit treatment X.
S: I would have thought they are negative because they minimised bias and the danger of generating a false positive result.
P: No, by minimising bias, as you put it, these trials eliminated the factors that are important elements of treatment X.
S: Such as the placebo-effect?
P: That’s what you call it because you irrationally believe in reductionist science.
S: Science requires no belief, I think you are the believer here.
P: The fact is that scientists of your ilk negate all factors related to human interactions. Patients are no machines, you know, they need compassion; we clinicians know that because we work at the coal face of health care. Scientists in their ivory towers have no idea about patient care and just want science for science sake. This is not how you help patients. Show some compassion man!
S: I do know about the importance of compassion and care, but here we are discussing an entirely different topic, namely tests the efficacy or effectiveness of treatments, not patient-care. Let’s focus on one issue at a time.
P: You cannot separate things in this way. We have to take a holistic view. Patients are whole individuals, and you cannot do them justice by running artificial experiments. Every patient is different; clinical trials fail to account for this fact and are therefore fairly irrelevant to us and to our patients. Real life is very different from your imagined little experiments, you know.
S: These are platitudes that are nonsensical in this context and do not contribute anything meaningful to the present discussion. You do not seem to understand the methodology or purpose of a clinical trial.
P: That is typical! Whenever you run out of arguments, you try to change the subject or throw a few insults at me.
S: Not at all, I thought we were talking about clinical trials evaluating the effectiveness of treatment X.
P: That’s right; and they do show that it is effective, provided you consider those which are truly well-done by experts who know about treatment X and believe in it.
S: Not true. Only if you cherry-pick the data will you be able to produce an overall positive result for treatment X.
P: In any case, the real world results of clinical practice show very clearly that it works. It would not have survived for so long, if it didn’t. Nobody can deny that, and nobody should claim that silly little trials done in artificial circumstances are more meaningful than a wealth of experience.
S: Experience has little to do with reliable evidence.
P: To deny the value of experience is just stupid and clearly puts you in the wrong. I have shown you plenty of reliable evidence but you just ignore everything I say that does not go along with your narrow-minded notions about science; science is not the only way of knowing or comprehending things! Stop being obsessed with science.
S: No, you show me rubbish data and have little understanding of science, I am afraid.
P: Here we go again! I have had about enough of that and your blinkered arguments. We are going in circles because you are ignorant and arrogant. I have tried my best to show you the light, but your mind is closed. I offer true insight and you pay me back with insults. You and your cronies are in the pocket of BIG PHARMA. You are cynical, heartless and not interested in the wellbeing of patients. Next you will tell me to vaccinate my kids!
S: I think this is a waste of time.
P: Precisely! Everyone who has followed this debate will see very clearly that you are obsessed with reductionist science and incapable of considering the suffering of whole individuals. You want to deny patients a treatment that really helps them simply because you do not understand how treatment X works. Shame on you!!!
Reiki is a form of healing which rests on the assumption that some form “energy” determines our health. In this context, I tend to put energy in inverted commas because it is not the energy a physicist might have in mind. It is a much more mystical entity, a form of vitality that is supposed to be essential for life and keep us going. Nobody has been able to define or quantify this “energy”, it defies scientific measurement and is biologically implausible. These circumstances render Reiki one of the least plausible therapies in the tool kit of alternative medicine.
Reiki-healers (they prefer to be called “masters”) would channel “energy” into his or her patient which, in turn, is thought to stimulate the healing process of whatever condition is being treated. In the eyes of those who believe in this sort of thing, Reiki is therefore a true panacea: it can heal everything.
The clinical evidence for or against Reiki is fairly clear – as one would expect after realising how ‘far out’ its underlying concepts are. Numerous studies are available, but most are of very poor quality. Their results tend to suggest that patients experience benefit after having Reiki but they rarely exclude the possibility that this is due to placebo or other non-specific effects. Those that are rigorous show quite clearly that Reiki is a placebo. Our own review therefore concluded that “the evidence is insufficient to suggest that Reiki is an effective treatment for any condition… the value of Reiki remains unproven.”
Since the publication of our article, a number of new investigations have become available. In a brand-new study, for instance, the researchers wanted to explore a Reiki therapy-training program for the care-givers of paediatric patients. A series of Reiki training classes were offered by a Reiki-master. At the completion of the program, interviews were conducted to elicit participant’s feedback regarding its effectiveness.
Seventeen families agreed to participate and 65% of them attended three Reiki training sessions. They reported that Reiki had benefited their child by improving their comfort (76%), providing relaxation (88%) and pain relief (41%). All caregivers thought that becoming an active participant in their child’s care was a major gain. The authors of this investigation conclude that “a hospital-based Reiki training program for caregivers of hospitalized pediatric patients is feasible and can positively impact patients and their families. More rigorous research regarding the benefits of Reiki in the pediatric population is needed.”
Trials like this one abound in the parallel world of “energy” medicine. In my view, such investigations do untold damage: they convince uncritical thinkers that “energy” healing is a rational and effective approach – so much so that even the military is beginning to use it.
The flaws in trials as the one above are too obvious to mention. Like most studies in this area, this new investigation proves nothing except the fact that poor quality research will mislead those who believe in its findings.
Some might say, so what? If a patient experiences benefit from a bogus yet harmless therapy, why not? I would strongly disagree with this increasingly popular view. Reiki and similarly bizarre forms of “energy” healing are well capable of causing harm.
Some fanatics might use these placebo-treatments as a true alternative to effective therapies. This would mean that the condition at hand remains untreated which, in a worst case scenario, might even lead to the death of patients. More important, in my view, is an entirely different risk: making people believe in mystic “energies” undermines rationality in a much more general sense. If this happens, the harm to society would be incalculable and extends far beyond health care.
Five years ago to the day, Simon Singh and I published an article in The Daily Mail to promote our book TRICK OR TREATMENT… which was then about to be launched. We recently learnt that our short article prompted a “confidential” message by the BRITISH CHIROPRACTIC ASSOCIATION to all its members. “Confidential” needs to be put in inverted commas because it is readily available on the Internet. I find it fascinating and of sufficient public interest to reproduce it here in full. I have not altered a thing in the following text, except putting it in italics and putting the section where the BCA quote our text in bold for clarity.
CONFIDENTIAL FOR BCA MEMBERS ONLY
Information for BCA members regarding an article in the Daily Mail – April 8th 2008
A double page spread appeared in the edition of the Daily Mail April 8th 2008 on page 46 and 47 and titled ‘Alternative Medicine The Verdict’.
The article was written by Simon Singh and Edzard Ernst and is a publicity prelude to a book they have written called ‘Trick or Treatment? Alternative Medicine on Trial’, which will be published later this month.
The article covers Alexander Technique, Aromatherapy, Flower Remedy, Chiropractic, Hypnotherapy, Magnet Therapy and Osteopathy.
The coverage of Chiropractic follows a familiar pattern for E Ernst. The treatment is oversimplified in explanation, with a heavy emphasis on words like thrust, strong and aggressive. There is tacit acknowledgement that chiropractic works for back pain, but then there is a long section about caution regarding neck manipulation. The article concludes by advising people not to have their neck manipulated and not to allow children to be treated.
WHAT IS IT? Chiropractors use spinal manipulation to realign the spine to restore mobility. Initial examination often includes X-ray images or MRI scans.
Spinal manipulation can be a fairly aggressive technique, which pushes the spinal joint slightly beyond what it is ordinarily capable of achieving, using a technique called high-velocity, low-amplitude thrust – exerting a relatively strong force in order to move the joint at speed, but the extent of the motion needs to be limited to prevent damage to the joint and its surrounding structures.
Although spinal manipulation is often associated with a cracking sound, this is not a result of the bones crunching or a sign that bones are being put back; the noise is caused by the release and popping of gas bubbles, generated when the fluid in the joint space is put under severe stress.
Some chiropractors claim to treat everything from digestive disorders to ear infections, others will treat only back problems.
DOES IT WORK? There is no evidence to suggest that spinal manipulation is effective for anything but back pain and even then conventional approaches (such as regular exercise and ibuprofen) are just as likely to be effective and are cheaper.
Neck manipulation has been linked to neurological complications such as strokes – in 1998, a 20-year-old Canadian woman died after neck manipulation caused a blood clot which led to stroke. We would strongly recommend physiotherapy exercises and osteopathy ahead of chiropractic therapy because they are at least effective and much safer.
If you do decide to visit a chiropractor despite our concerns and warnings, we very strongly recommend you confirm your chiropractor won’t manipulate your neck. The dangers of chiropractic therapy to children are particularly worrying because a chiropractor would be manipulating an immature spine.
Daily Mail 2008 April 8th.
As we are aware that patients or potential patients of our members will be confronted with questions regarding this article, we have put together some comment and Q&As to assist you.
• Please consider this information as strictly confidential and for your use only.
• Only use this if a patient asks about these specific issues; there is nothing to be gained from releasing any information not asked for.
• Do not duplicate these patient notes and hand out direct to the patient or the media; these are designed for you to use when in direct conversation with a patient.
The BCA will be very carefully considering any questions or approaches we may receive from the press and will respond to them using specially briefed spokespeople. We would strongly advise our members not to speak directly to the press on any of the issues raised as a result of this coverage.
Please note that In the event of you receiving queries from the media, please refer these direct to BCA (0118 950 5950 – Anne Barlow or Sue Wakefield) or Publicasity (0207 632 2400 – Julie Doyle or Sara Bailey).
The following points should assist you in answering questions that patients may ask with regard to the safety and effectiveness of chiropractic care. Potential questions are detailed along with the desired ‘BCA response’:
o “The Daily Mail article seems to suggest chiropractic treatment is not that effective”
Nothing could be further from the truth. The authors have had to concede that chiropractic treatment works for back pain as there is overwhelming evidence to support this. The authors also contest that pain killers and exercises can do the job just as well. What they fail to mention is that research has shown that this might be the case for some patients, but the amount of time it may take to recover is a lot longer and the chance of re-occurrence of the problem is higher. This means that chiropractic treatment works, gets results more quickly and helps prevent re-occurrence of the problem. Chiropractic is the third largest healthcare profession in the world and in the UK is recognised and regulated by the UK Government.
o “The treatment is described as aggressive, can you explain?”
It is important to say that the authors of the article clearly have no direct experience of chiropractic treatment, nor have they bothered to properly research the training and techniques. Chiropractic treatment can take many forms, depending on the nature of the problem, the particular patient’s age and medical history and other factors. The training chiropractors receive is overseen by the government appointed regulator and the content of training is absolutely designed to ensure that an individual chiropractor understands exactly which treatment types are required in each individual patient scenario. Gentle technique, massage and exercise are just some of the techniques available in the chiropractor’s ‘toolkit’. It is a gross generalisation and a demonstration of lack of knowledge of chiropractic to characterise it the way it appeared in the article.
o “The article talked about ‘claims’ of success with other problems”
There is a large and undeniable body of evidence regarding the effectiveness of chiropractic treatment for musculoskeletal problems such as back pain. There is also growing evidence that chiropractic treatment can help many patients with other problems; persistent headaches for example. There is also anecdotal evidence and positive patient experience to show that other kinds of problems have been helped by chiropractic treatment. For many of these kinds of problems, the formal research is just beginning and a chiropractor would never propose their treatment as a substitute for other, ongoing treatments.
o “Am I at risk of having a stroke if I have a chiropractic treatment?”
What is important to understand is that any association between neck manipulation and stroke is extremely rare. Chiropractic is a very safe form of treatment.
Another important point to understand is that the treatments employed by chiropractors are statistically safer than many other conservative treatment options (such as ibuprofen and other pain killers with side effects such as gastric bleeding) for mechanical low back or neck pain conditions.
A research study in the UK, published just last year studied the neck manipulations received by nearly 20,000 chiropractic patients. NO SERIOUS ADVERSE SIDE EFFECTS WERE IDENTIFIED AT ALL. In another piece of research, published in February this year, stroke was found to be a very rare event and the risk associated with a visit to a chiropractor appeared to be no different from the risk of a stroke following a visit to a GP.
Other recent research shows that such an association with stroke may occur once in every 5.85 million adjustments.
To put this in context, a ‘significant risk’ for any therapeutic intervention (such as pain medication) is defined as 1 in 10,000.
Additional info: Stroke is a natural occurring phenomenon, and evidence dictates that a number of key risk factors increase the likelihood of an individual suffering a stroke. Smoking, high blood pressure, high cholesterol and family medical histories can all contribute; rarely does a stroke occur in isolation from these factors. Also, stroke symptoms can be similar to that of upper neck pains, stiffness or headaches, conditions for which patients may seek chiropractic treatment. BCA chiropractors are trained to recognise and diagnose these symptoms and advise appropriate mainstream medical care.
o “Can you tell if I am at risk from stroke?”
As a BCA chiropractor I am trained to identify risk factors and would not proceed with treatment if there was any doubt as to the patient’s suitability. Potential risks may come to light during the taking of a case history, which may include: smoking, high cholesterol, contraceptive pill, Blood clotting problems/blood thinning meds, heart problems, trauma to the head etc and on physical examination e.g. high blood pressure, severe osteoarthritis of the neck, history of rheumatoid arthritis
o “Do you ever tell patients if they are at risk?”
Yes, I would always discuss risks with patients and treatment will not proceed without informed consent.
o “Is it safe for my child to be treated by a chiropractor”
It is a shame that the article so generalises the treatment provided by a chiropractor, that it makes such outrageous claims. My training in anatomy, physiology and diagnosis means that I absolutely understand the demands and needs of spines from the newborn baby to the very elderly patient. The techniques and treatments I might use on a 25 year old are not the same as those I would employ on a 5 year old. I see a lot of children as patients at this clinic and am able to offer help with a variety of problems with the back, joints and muscles. I examine every patient very thoroughly, understand their medical history and discuss my findings with them and their parents before undertaking any treatment.
– Chiropractic is a mature profession and numerous studies clearly demonstrate that chiropractic treatment, including manipulative and spinal adjustment, is both safe and effective.
– Thousands of patients are treated by me and my fellow chiropractors every day in the UK. Chiropractic is a healthcare profession that is growing purely because our patients see the results and GPs refer patients to us because they know we get results!
This article is to promote a book and a controversial one at that. Certainly, in the case of the comments about chiropractic, there is much evidence and research that has formed part of guidelines developed by the Royal Society of General Practitioners, NICE and other NHS/Government agencies, has been conveniently ignored. The statements about chiropractic treatment and technique demonstrate that there has clearly been no research into the actual education that chiropractors in the UK receive – in my case a four year full-time degree course that meets stringent educational standards set down by the government appointed regulator.
Shortly after the article in The Daily Mail, our book was published and turned out to be much appreciated by critical thinkers across the globe — not, however, by chiropractors.
At the time, I did, of course, not know about the above “strictly confidential” message to BCA members, yet I strongly suspected that chiropractors would do everything in their power to dispute our central argument, namely that most of the therapeutic claims by chiropractors were not supported by sufficient evidence. I also knew that our evidence for it was rock solid; after all, I had researched the evidence for or against chiropractic in full depth and minute detail and published dozens of articles on the subject in the medical literature.
When, one and a half weeks after our piece in the Mail, Simon published his now famous Guardian comment stating that the BCA “happily promote bogus treatments”, he was sued for libel by the BCA. I think the above “strictly confidential” message already reveals the BCA’s determination and their conviction to be on firm ground. As it turned out, they were wrong. Not only did they lose their libel suit, but they also dragged chiropractic into a deep crisis.
The “strictly confidential” message is intriguing in several more ways – I will leave it to my readers to pick out some of the many gems hidden in this text. Personally, I find the most remarkable aspect that the BCA seems to attempt to silence its own members regarding the controversy about the value of their treatments. Instead they proscribe answers (should I say doctrines?) of highly debatable accuracy for them, almost as though chiropractors were unable to speak for themselves. To me, this smells of cult-like behaviour, and is by no means indicative of a mature profession – despite their affirmations to the contrary.
There probably is no area in health care that produces more surveys than alternative medicine. I estimate that about 500 surveys are published every year; this amounts to about two every working day which is substantially more than the number of clinical trials in this field.
I have long been critical of this ‘survey-mania’. The reason is simple: most of these articles are of such poor quality that they tell us nothing of value.
The vast majority of these surveys attempts to evaluate the prevalence of use of alternative medicine, and it is this type of investigation that I intend to discuss here.
For a typical prevalence survey, a team of enthusiastic researchers might put together a few questions and design a questionnaire to find out what percentage of a group of individuals have tried alternative medicine in the past. Subsequently, the investigators might get one or two hundred responses. They then calculate simple descriptive statistics and demonstrate that xy% (let’s assume it is 45%) use alternative medicine. This finding eventually gets published in one of the many alternative medicine journals, and everyone is happy – well, almost everybody.
How can I be such a spoil-sport and claim that this result tells us nothing of value? At the very minimum, some might argue, it shows that enthusiasts of alternative medicine are interested in and capable of conducting research. I beg to differ: this is not research, it is pseudo-research which ignores most of the principles of survey-design.
The typical alternative medicine prevalence survey has none of the features that would render it a scientific investigation:
1) It lacks an accepted definition of what is being surveyed. There is no generally accepted definition of alternative medicine, and even if the researchers address specific therapies, they run into huge problems. Take prayer, for instance – some see this as alternative medicine, while others would, of course, argue that it is a religious pursuit. Or take herbal medicine – many consumers confuse it with homeopathy, some might think that drinking tea is herbal medicine, while others would probably disagree.
2) The questionnaires used for such surveys are almost never validated. Essentially, this means that we cannot be sure they evaluate what we think they evaluate. We all know that the way we formulate a question can determine the answer. There are many potential sources of bias here, and they are rarely taken into consideration.
3) Enthusiastic researchers of alternative medicine usually use a small convenience sample of participants for their surveys. This means they ask a few people who happen to be around to fill their questionnaire. As a consequence, there is no way the survey is representative of the population in question.
4) The typical survey has a low response rate; sometimes the response rate is not even provided or remains unknown even to the investigators. This means we do not know how the majority of patients/consumers who received but did not fill the questionnaire would have answered. Often there is good reason to suspect that those who have a certain attitude did respond, while those with a different opinion did not. This self-selection process is likely to produce misleading findings.
And why I am so sure about all of theses limitations? To my embarrassment, I know about them not least because I have made most these mistakes myself at some time in my career. You might also ask why this is important: what’s the harm in publishing a few flimsy surveys?
In my view, these investigations are regrettably counter-productive because:
they tend to grossly over-estimate the popularity of alternative medicine,
they distract money, manpower and attention from the truly important research questions in this field,
they give a false impression of a buoyant research activity,
and their results are constantly misused.
The last point is probably the most important one. The argument that is all too often spun around such survey data goes roughly as follows: a large percentage of the population uses alternative medicine; people pay out of their own pocket for these treatments; they are satisfied with them (if not, they would not pay for them). BUT THIS IS GROSSLY UNFAIR! Why should only those individuals who are rich enough to afford alternative medicine benefit from it? ALTERNATIVE MEDICINE SHOULD BE MADE AVAILABLE FOR ALL.
I rest my case.
The ‘Samueli Institute’ might be known to many readers of this blog; it is a wealthy institution that is almost entirely dedicated to promoting the more implausible fringe of alternative medicine. The official aim is “to create a flourishing society through the scientific exploration of wellness and whole-person healing“. Much of its activity seems to be focused on military medical research. Its co-workers include Harald Walach who recently was awarded a rare distinction for his relentless efforts in introducing esoteric pseudo-science into academia.
Now researchers from the Californian branch of the Samueli Institute have published an articles whic, in my view, is another landmark in nonsense.
Jain and colleagues conducted a randomized controlled trial to determine whether Healing Touch with Guided Imagery [HT+GI] reduced post-traumatic stress disorder (PTSD) compared to treatment as usual (TAU) in “returning combat-exposed active duty military with significant PTSD symptoms“. HT is a popular form of para-normal healing where the therapist channels “energy” into the patient’s body; GI is a self-hypnotic from of relaxation-therapy. While the latter approach might be seen as plausible and, at least to some degree, evidence-based, the former cannot.
123 soldiers were randomized to 6 sessions of HT+GI, while the control group had no such therapies. All patients also received standard conventional therapies, and the treatment period was three weeks. The results showed significant reductions in PTSD symptoms as well as depression for HT+GI compared to controls. HT+GI also showed significant improvements in mental quality of life and cynicism.
The authors concluded that HT+GI resulted in a clinically significant reduction in PTSD and related symptoms, and that further investigations of biofield therapies for mitigating PTSD in military populations are warranted.
The Samueli Institute claims to “support science grounded in observation, investigation, and analysis, and [to have] the courage to ask challenging questions within a framework of systematic, high-quality, research methods and the peer-review process“. I do not think that the above-named paper lives up to these standards.
As discussed in some detail in a previous post, this type of study-design is next to useless for determining whether any intervention does any good at all: A+B is always more than B alone! Moreover, if we test HT+GI as a package, how can we conclude about the effectiveness of one of the two interventions? Thus this trial tells us next to nothing about the effectiveness of HT, nor about the effectiveness of HT+GI.
Previously, I have argued that conducting a trial for which the result is already clear before the first patient has been recruited, is not ethical. Samueli Institute, however, claims that it “acts with the highest respect for the public it serves by ensuring transparency, responsible management and ethical practices from discovery to policy and application“. Am I the only one who senses a contradiction here?
Perhaps other research in this area might be more informative? Even the most superficial Medline-search brings to light a flurry of articles on HT and other biofield therapies that are relevant.
Several trials have indeed produces promissing evidence suggesting positive effects of such treatments on anxiety and other symptoms. But the data are far from uniform, and most investigations are wide open to bias. The more rigorous studies seem to suggest that these interventions are not effective beyond placebo. Our review demonstrated that “the evidence is insufficient” to suggest that reiki, another biofield therapy, is an effective treatment for any condition.
Another study showed that tactile touch led to significantly lower levels of anxiety. Conventional massage may even be better than HT, according to some trials. The conclusion from this body of evidence is, I think, fairly obvious: touch can be helpful (most clinicians knew that anyway) but this has nothing to do with energy, biofields, healing energy or any of the other implausible assumptions these treatments are based on.
I therefore disagree with the authors’ conclusion that “further investigation into biofield therapies… is warranted“. If we really want to help patients, let’s find out more about the benefits of touch and let’s not mislead the public about some mystical energies and implausible quackery. And if we truly want to improve heath care, as the Samueli Institute claims, let’s use our limited resources for research which meaningfully contributes to our knowledge.
On January 27, 1945, the concentration camp in Auschwitz was liberated. By May of the same year, around 20 similar camps had been discovered. What they revealed is so shocking that it is difficult to put it in words.
Today, on ‘HOCOCAUST MEMORIAL DAY’, I quote (shortened and slightly modified) from articles I published many years ago (references can be found in the originals) to remind us of the unspeakable atrocities that occurred during the Nazi period and of the crucial role the German medical profession played in them.
The Nazi’s euthanasia programme, also known as “Action T4″, started in specialized medicinal departments in 1939. Initially, it was aimed at children suffering from “idiocy, Down’s syndrome, hydrocephalus and other abnormalities”. By the end of 1939, the programme was extended to adults “unworthy of living.” We estimate that, when it was stopped, more than 70,000 patients had been killed.
Action T4 (named after its address: Tiergarten Strasse 4) was the Berlin headquarters of the euthanasia programme. It was run by approximately 50 physicians who, amongst other activities, sent questionnaires to (mostly psychiatric) hospitals urging them to return lists of patients for euthanasia. The victims were transported to specialized centers where they were gassed or poisoned. Action T4 was thus responsible for medically supervised, large-scale murder. Its true significance, however, lies elsewhere. Action T4 turned out to be nothing less than a “pilot project” for the extinction of millions of prisoners of the concentration camps.
The T4 units had developed the technology for killing on an industrial scale. It was only with this know-how that the total extinction of all Jews of the Reich could be planned. This truly monstrous task required medical expertise.
Almost without exception, those physicians who had worked for T4 went on to take charge of what the Nazis called the ‘Final Solution’. While action T4 had killed thousands, its offspring would murder millions under the trained instructions of Nazi doctors.
The medical profession’s role in these crimes was critical and essential. German physicians had been involved at all levels and stages. They had created and embraced the pseudo-science of race hygiene. They were instrumental in developing it further into applied racism. They had generated the know-how of mass extinction. Finally, they also performed outrageously cruel and criminal experiments under the guise of scientific inquiry [see below]. German doctors had thus betrayed all the ideals medicine had previously stood for, and had become involved in criminal activities unprecedented in the history of medicine (full details and references on all of this are provided in my article, see link above).
It is well-documented that alternative medicine was strongly supported by the Nazis. The general belief is that this had nothing to do with the sickening atrocities of this period. I believe that this assumption is not entirely correct. In 2001, I published an article which reviews the this subject; I take the liberty of borrowing from it here.
Based on a general movement in favour of all things natural, a powerful trend towards natural ways of healing had developed in the 19(th)century. By 1930, this had led to a situation in Germany where roughly as many lay-practitioners of alternative medicine as conventional doctors were in practice.This had led to considerable tensions between the two camps. To re-unify German medicine under the banner of ‘Neue Deutsche Heilkunde’ (New German Medicine), Nazi officials eventually decided to create the profession of the ‘Heilpraktiker‘ (healing practitioner). Heilpraktiker were not allowed to train students and their profession was thus meant to become extinct within one generation; Goebbels spoke of having created the cradle and the grave of the Heilpraktiker. However, after 1945, this decision was challenged in the courts and eventually over-turned – and this is why Heilpraktiker are still thriving today.
The ‘flag ship’ of the ‘Neue Deutsche Heilkunde’ was the ‘Rudolf Hess Krankenhaus‘ in Dresden (which was re-named into Gerhard Wagner Krankenhaus after Hess’ flight to the UK). It represented a full integration of alternative and orthodox medicine.
An example of systematic research into alternative medicine is the Nazi government’s project to validate homoeopathy. The data of this massive research programme are now lost (some speculate that homeopaths made them disappear) but, according to an eye-witness report, its results were entirely negative (full details and references on alt med in 3rd Reich are in the article cited above).
There is,of course, plenty of literature on the subject of Nazi ‘research’ (actually, it was pseudo-research) and the unspeakable crimes it entailed. By contrast, there is almost no published evidence that these activities included in any way alternative medicine, and the general opinion seems to be that there are no connections whatsoever. I fear that this notion might be erroneous.
As far as I can make out, no systematic study of the subject has so far been published, but I found several hints and indications that the criminal experiments of Nazi doctors also involved alternative medicine (the sources are provided in my articles cited above or in the links provided below). Here are but a few leads:
Dr Wagner, the chief medical officer of the Nazis was a dedicated and most active proponent of alternative medicine.
Doctors in the alternative “Rudolf Hess Krankenhaus” [see above] experimented on speeding up the recovery of wounded soldiers, on curing syphilis with fasting, and on various other projects to help the war effort.
The Dachau concentration camp housed the largest plantation of medicinal herbs in Germany.
Dr Madaus (founder of the still existing company for natural medicines by the same name) experimented on the sterilisation of humans with herbal and homeopathic remedies, a project that was deemed of great importance for controlling the predicted population growth in the East of the expanding Reich.
Dr Grawitz infected Dachau prisoners with various pathogens to test the effectiveness of homeopathic remedies.
Schuessler salts were also tested on concentration camp inmates.
So, why bring all of this up today? Is it not time that we let grass grow over these most disturbing events? I think not! For many years, I actively researched this area (you can find many of my articles on Medline) because I am convinced that the unprecedented horrors of Nazi medicine need to be told and re-told – not just on HOLOCAUST MEMORIAL DAY, but continually. This, I hope, will minimize the risk of such incredible abuses ever happening again.
As I am drafting this post, I am in a plane flying back from Finland. The in-flight meal reminded me of the fact that no food is so delicious that it cannot be spoilt by the addition of too many capers. In turn, this made me think about the paper I happened to be reading at the time, and I arrived at the following theory: no trial design is so rigorous that it cannot to be turned into something utterly nonsensical by the addition of a few amateur researchers.
The paper I was reading when this idea occurred to me was a randomised, triple-blind, placebo-controlled cross-over trial of homeopathy. Sounds rigorous and top quality? Yes, but wait!
Essentially, the authors recruited 86 volunteers who all claimed to be suffering from “mental fatigue” and treated them with Kali-Phos 6X or placebo for one week (X-potencies signify dilution steps of 1: 10, and 6X therefore means that the salt had been diluted 1: 1000000 ). Subsequently, the volunteers were crossed-over to receive the other treatment for one week.
The results failed to show that the homeopathic medication had any effect (not even homeopaths can be surprised about this!). The authors concluded that Kali-Phos was not effective but cautioned that, because of the possibility of a type-2-error, they might have missed an effect which, in truth, does exist.
In my view, this article provides an almost classic example of how time, money and other resources can be wasted in a pretence of conducting reasonable research. As we all know, clinical trials usually are for testing hypotheses. But what is the hypothesis tested here?
According to the authors, the aim was to “assess the effectiveness of Kali-Phos 6X for attention problems associated with mental fatigue”. In other words, their hyposesis was that this remedy is effective for treating the symptom of mental fatigue. This notion, I would claim, is not a scientific hypothesis, it is a foolish conjecture!
Arguably any hypothesis about the effectiveness of a highly diluted homeopathic remedy is mere wishful thinking. But, if there were at least some promissing data, some might conclude that a trial was justified. By way of justification for the RCT in question, the authors inform us that one previous trial had suggested an effect; however, this study did not employ just Kali-Phos but a combined homeopathic preparation which contained Kalium-Phos as one of several components. Thus the authors’ “hypothesis” does not even amount to a hunch, not even to a slight incling! To me, it is less than a shot in the dark fired by blind optimists – nobody should be surprised that the bullet failed to hit anything.
It could even be that the investigators themselves dimly realised that something is amiss with the basis of their study; this might be the reason why they called it an “exploratory trial”. But an exploratory study is one whithout a hypothesis, and the trial in question does have a hyposis of sorts – only that it is rubbish. And what exactly did the authos meant to explore anyway?
That self-reported mental fatigue in healthy volunteers is a condition that can be mediatised such that it merits treatment?
That the test they used for quantifying its severity is adequate?
That a homeopathic remedy with virtually no active ingredient generates outcomes which are different from placebo?
That Hahnemann’s teaching of homeopathy was nonsense and can thus be discarded (he would have sharply condemned the approach of treating all volunteers with the same remedy, as it contradicts many of his concepts)?
That funding bodies can be fooled to pay for even the most ridiculous trial?
That ethics-committees might pass applications which are pure nonsense and which are thus unethical?
A scientific hypothesis should be more than a vague hunch; at its simplest, it aims to explain an observation or phenomenon, and it ought to have certain features which many alt med researchers seem to have never heard of. If they test nonsense, the result can only be nonsense.
The issue of conducting research that does not make much sense is far from trivial, particularly as so much (I would say most) of alt med research is of such or even worst calibre (if you do not believe me, please go on Medline and see for yourself how many of the recent articles in the category “complementary alternative medicine” truly contribute to knowledge worth knowing). It would be easy therefore to cite more hypothesis-free trials of homeopathy.
One recent example from Germany will have to suffice: in this trial, the only justification for conducting a full-blown RCT was that the manufacturer of the remedy allegedly knew of a few unpublished case-reports which suggested the treatment to work – and, of course, the results of the RCT eventually showed that it didn’t. Anyone with a background in science might have predicied that outcome – which is why such trials are so deplorably wastefull.
Research-funds are increasingly scarce, and they must not be spent on nonsensical projects! The money and time should be invested more fruitfully elsewhere. Participants of clinical trials give their cooperation willingly; but if they learn that their efforts have been wasted unnecessarily, they might think twice next time they are asked. Thus nonsensical research may have knock-on effects with far-reaching consequences.
Being a researcher is at least as serious a profession as most other occupations; perhaps we should stop allowing total amateurs wasting money while playing at being professioal. If someone driving a car does something seriously wrong, we take away his licence; why is there not a similar mechanism for inadequate researchers, funders, ethics-committees which prevents them doing further damage?
At the very minimum, we should critically evaluate the hypothesis that the applicants for research-funds propose to test. Had someone done this properly in relatiom to the two above-named studies, we would have saved about £150,000 per trial (my estimate). But as it stands, the authors will probably claim that they have produced fascinating findings which urgently need further investigation – and we (normally you and I) will have to spend three times the above-named amount (again, my estimate) to finance a “definitive” trial. Nonsense, I am afraid, tends to beget more nonsense.
In these austere and difficult times, it must be my duty, I think, to alert my fellow citizens to a possible source of additional income which almost anyone can plug into: become a charlatan, and chances are that your economic hardship is a memory from the past. To achieve this aim, I [with my tongue firmly lodged in my cheek] suggest a fairly straight forward step by step approach.
1. Find an attractive therapy and give it a fantastic name
Did I just say “straight forward”? Well, the first step isn’t that easy, after all. Most of the really loony ideas turn out to be taken: ear candles, homeopathy, aura massage, energy healing, urine-therapy, chiropractic etc. As a true charlatan, you want your very own quackery. So you will have to think of a new concept.
Something truly ‘far out’ would be ideal, like claiming the ear is a map of the human body which allows you to treat all diseases by doing something odd on specific areas of the ear – oops, this territory is already occupied by the ear acupuncture brigade. How about postulating that you have super-natural powers which enable you to send ‘healing energy’ into patients’ bodies so that they can repair themselves? No good either: Reiki-healers might accuse you of plagiarism.
But you get the gist, I am sure, and will be able to invent something. When you do, give it a memorable name, the name can make or break your new venture.
2. Invent a fascinating history
Having identified your treatment and a fantastic name for it, you now need a good story to explain how it all came about. This task is not all that tough and might even turn out to be fun; you could think of something touching like you cured your moribund little sister at the age of 6 with your intervention, or you received the inspiration in your dreams from an old aunt who had just died, or perhaps you want to create some religious connection [have you ever visited Lourdes?]. There are no limits to your imagination; just make sure the story is gripping – one day, they might make a movie of it.
3. Add a dash of pseudo-science
Like it or not, but we live in an age where we cannot entirely exclude science from our considerations. At the very minimum, I recommend a little smattering of sciency terminology. As you don’t want to be found out, select something that only few experts understand; quantum physics, entanglement, chaos-theory and Nano-technology are all excellent options.
It might also look more convincing to hint at the notion that top scientists adore your concepts, or that whole teams from universities in distant places are working on the underlying mechanisms, or that the Nobel committee has recently been alerted etc. If at all possible, add a bit of high tech to your new invention; some shiny new apparatus with flashing lights and digital displays might be just the ticket. The apparatus can be otherwise empty – as long as it looks impressive, all is fine.
4. Do not forget a dose of ancient wisdom
With all this science – sorry, pseudo-science – you must not forget to remain firmly grounded in tradition. Your treatment ought to be based on ancient wisdom which you have rediscovered, modified and perfected. I recommend mentioning that some of the oldest cultures of the planet have already been aware of the main pillars on which your invention today proudly stands. Anything that is that old has stood the test of time which is to say, your treatment is both effective and safe.
5. Claim to have a panacea
To maximise your income, you want to have as many customers as possible. It would therefore be unwise to focus your endeavours on just one or two conditions. Commercially, it is much better to affirm in no uncertain terms that your treatment is a cure for everything, a panacea. Do not worry about the implausibility of such a claim. In the realm of quackery, it is perfectly acceptable, even common behaviour to be outlandish.
6. Deal with the ‘evidence-problem’ and the nasty sceptics
It is depressing, I know, but even the most exceptionally gifted charlatan is bound to attract doubters. Sceptics will sooner or later ask you for evidence; in fact, they are obsessed by it. But do not panic – this is by no means as threatening as it appears. The obvious solution is to provide testimonial after testimonial.
You need a website where satisfied customers report impressive stories how your treatment saved their lives. In case you do not know such customers, invent them; in the realm of quackery, there is a time-honoured tradition of writing your own testimonials. Nobody will be able to tell!
7. Demonstrate that you master the fine art of cheating with statistics
Some of the sceptics might not be impressed, and when they start criticising your ‘evidence’, you might need to go the extra mile. Providing statistics is a very good way of keeping them at bay, at least for a while. The general consensus amongst charlatans is that about 70% of their patients experience remarkable benefit from whatever placebo they throw at them. So, my advice is to do a little better and cite a case series of at least 5000 patients of whom 76.5 % showed significant improvements.
What? You don’t have such case series? Don’t be daft, be inventive!
8. Score points with Big Pharma
You must be aware who your (future) customers are (will be): they are affluent, had a decent education (evidently without much success), and are middle-aged, gullible and deeply alternative. Think of Prince Charles! Once you have empathised with this mind-set, it is obvious that you can profitably plug into the persecution complex which haunts these people.
An easy way of achieving this is to claim that Big Pharma has got wind of your innovation, is positively frightened of losing millions, and is thus doing all they can to supress it. Not only will this give you street cred with the lunatic fringe of society, it also provides a perfect explanation why your ground-breaking discovery has not been published it the top journals of medicine: the editors are all in the pocket of Big Pharma, of course.
9. Ask for money, much money
I have left the most important bit for the end; remember: your aim is to get rich! So, charge high fees, even extravagantly high ones. If your treatment is a product that you can sell (e.g. via the internet, to escape the regulators), sell it dearly; if it is a hands-on therapy, charge heavy consultation fees and claim exclusivity; if it is a teachable technique, start training other therapists at high fees and ask a franchise-cut of their future earnings.
Over-charging is your best chance of getting famous – or have you ever heard of a charlatan famous for being reasonably priced? It will also get rid of the riff-raff you don’t want to see in your surgery. Poor people might be even ill! No, you don’t want them; you want the ‘worried rich and well’ who can afford to see a real doctor when things should go wrong. But most importantly, high fees will do a lot of good to your bank account.
Now you are all set. However, to prevent you from stumbling at the first hurdle, here are some handy answers to the questions you inevitably will receive from sceptics, this nasty breed that is never happy. The answers are not designed to convince them but, if voiced in public, they will ensure that the general opinion is on your side – and that’s what is paramount in the realm of quackery.
Q: Your treatment can cause considerable harm; do you find that responsible?
A: Harm? Do you know what you are talking about? Obviously not! Every year, hundreds of thousands die because of the medicine they received from mainstream doctors. This is what I call harm!
Q: Experts say that your treatment is not biologically plausible, what is your response?
A: There are many things science does not yet understand and many things that it will never understand. In any case, there are other ways of knowing, and science is but one of them.
Q: Where are the controlled trials to back up your claim?
A: Clinical trials are of very limited value; they are far too small, frequently biased and never depict the real life situation. This is why many experts now argue for better ways of showing the value of medical interventions.
Q: Professor Ernst recently said that your therapy is unproven, is that true?
A: This man cannot be trusted; he is in the pocket of the pharmaceutical industry! He would say that, wouldn’t he?
Anyway, did you know that only 15% of conventional therapies actually are evidence-based?
Q: Why is your treatment so expensive?
A: Years of training, a full research programme, constant audits, compliance with regulations, and a large team of co-workers – do you think that all of this comes free? Personally, I would treat all my patients for free (and often do so) but I have responsibilities to others, you know.
