Crank “scientific” conferences: A parody of science-based medicine that can deceive even reputable scientists and institutions

If there’s one thing that purveyors of pseudoscientific medical modalities crave, probably above all else, it’s legitimacy. They want to be taken seriously as Real Scientists. Of course, my usual reaction to this desire is to point out that anyone can be take seriously as a real scientist if he is able to do science and that science actually shows that there is something to his claims. In other words, do his hypotheses make testable predictions, and does testing these predictions fail to falsify his hypotheses? That’s what it takes, but advocates of so-called “complementary and alternative medicine” (CAM) or “integrative medicine” (IM, or, as I like to refer to it: “integrating” quackery with scientific medicine) want their woo to be considered science without actually doing the hard work of science.

There are several strategies that pseudoscientists use to give their beliefs the appearance of science, a patina of “science-y” camouflage, if you will. One, of course, is the cooptation and corruption of the language of science, which has been a frequent topic on this blog, particularly in posts written by Drs. Atwood and Sampson. Another is to produce journals that appear to be science, but are anything but. I’ve discussed one example, the Journal of American Physicians and Surgeons and Medical Acupuncture, but others include Homeopathy, the Journal of Alternative and Complementary Medicine, and Medical Hypotheses, which recently was forced to retract a horrible paper by arch-HIV/AIDS denialist Peter Duesberg. What’s worse is that some of these journals are even published by what are considered major publishers, such as Mary Ann Liebert, Inc., and Elsevier.

There is, however, a third strategy. How do scientists communicate their findings to other scientists, as well as meeting and mingling with other scientists? Why, they hold scientific meetings, of course! These meetings can be small or even as large as the American Association for Cancer Research meeting, which is attended by around 15,000 cancer researchers each year. So, too, do cranks hold meetings. These meetings often have all the trappings of scientific meetings, with plenary sessions, smaller parallel sessions, poster sesssions, and an exhibition hall, complete with exhibits by sponsoring companies. Sometimes these meetings can even appear so much like the real thing that they take in legitimate researchers and legitimate universities. Here, I present two examples of such conferences.

Even with the H1N1 pandemic flu strain going around, you should still be vaccinated against the seasonal flu

Even with the H1N1 pandemic flu going around you should still be vaccinated against the seasonal flu. revere has the details. Read. Enjoy. Be educated.

I guess that means Dr. Doug Bremner must think that revere is an idiot. After all, Bremner tells us that the flu vaccine is all a plot for big pharma to make money, don’t you know? Subtlety and weighing of risk-benefit ratios in a manner that doesn’t turn into an anti-big pharma rant is beyond him, as both Peter Lipson and I discussed (and Peter discussed again) not too long ago.

Fortunately it is not beyond revere to rationally weigh the risks and benefits of being vaccinated:

The truth is this. No one knows what’s going to happen. We’re all guessing. But in my estimation, the risk-benefit calculation for vaccine side-effects and flu is so markedly in favor of the vaccine that I made the decision to get vaccinated and that’s what I’d advise others, too. How confident am I? I’m confident it is the most rational thing to do given what we know.

Exactly. It is quite possible to look at the evidence and science and decide that the risk-benefit ratio is so much in favor of vaccination that it makes sense to be vaccinated. It’s also possible to look at the same literature and be less enthusiastic. You don’t need to appeal to big pharma conspiracy theories, and, in fact, such appeals only muddy the issue unnecessarily.

I’d love to see Bremner try to counter the arguments of a highly respected senior epidemiologist who can calmly discuss the pros and cons of flu vaccines from a scientific and practical standpoint based on evidence. Bremner points to “experts” who say that vaccination against the seasonal flu is a waste of money and time, but here’s one expert I bet that Bremner can’t refute. I won’t hold my breath waiting for him to try, though. It’s so much easier just to say that you’re an idiot if you get vaccinated against the seasonal flu. Obviously, in Bremner’s world, revere must be in the thrall of big pharma and pro-vaccination ideology.

Just like me, I guess.

An open letter to Dr. J. Douglas Bremner

Peter Lipson wrote a post last week entitled Before You Trust That Blog…, which was a criticism of Dr. J. Douglas Bremner’s blog Before You Take That Pill. Dr. Bremner was not pleased, and posted a rebuttal entitled Response to Peter Lipson MD of “Science” Based Blogs, My Blog Does Not Suck, Yours Does. Given the kerfuffle and my role as managing editor of SBM, I felt the need to put my two cents in, which is why I’m posting this open letter to Dr. Bremner. This letter started as a much briefer response that I was going to e-mail to Dr. Bremner, but as I wrote it grew and grew to the point where I decided that, given the public nature of the disagreement between Dr. Lipson and Dr. Bremner, I might as well make my commentary public too. Consider it a bonus post from me. I still plan a post for my usual slot on Monday. In the meantime, here’s my open letter:

“There must be a reason,” or how we support our own false beliefs

ResearchBlogging.orgFor a change of pace, I want to step back from medicine for this post, although, as you will see (I hope), the study I’m going to discuss has a great deal of relevance to the topics covered regularly on this blog. One of the most frustrating aspects of being a skeptic and championing science-based medicine is just how unyielding belief in pseudscience is. Whatever realm of science in which there is pseudoscience I wander into, I find beliefs that simply will not yield to science or reason. Whether it be creationism, quackery such as homeopathy, the anti-vaccine movement, the “9/11 Truth” movement, moon hoaxers, or any of a number of pseudoscientific movements and conspiracy theories, any skeptic who ventures into discussions of such a topic with believers will become very frustrated very fast. It takes a lot of tenacity to keep going back to the well to argue the same points over and over again and refute the same nonsense you’ve refuted over and over again. Many do not have sufficient stick-to-it-iveness, leading them to throw up their hands and withdraw from the fight.

Although some of us here have blamed this phenomenon on “cultishness” and, make no mistake, I do think that there is an element of that in many of these movement, particularly the anti-vaccine movements, cultishness alone can’t explain why people hold on so hard to beliefs that are clearly not supported by science or evidence, such as the belief that vaccines are responsible for an “autism epidemic.” Then last week, what should pop up in the newsfeeds that I regularly monitor but a rather interesting article in Science Daily entitled How We Support Our False Beliefs. It was a press release about a study1 that appeared a few months ago in Sociological Inquiry, and the the study was described thusly:

The perils and pitfalls of doing a “vaccinated versus unvaccinated” study

The anti-vaccine movement is nothing if not plastic. It “evolves” very rapidly in response to selective pressures applied to it in the form of science refuting its key beliefs. For instance, when multiple studies looking at the MMR vaccine and autism failed to confirm the myth that the MMR causes autism or “autistic enterocolitis,” most recently late last year, it was not a problem to the anti-vaccine movement. Neither was it a major problem to the movement when multiple studies similarly failed to find a link between mercury in the preservative thimerosal that used to be in most childhood vaccines and is no more (except the flu vaccine) and autism. No problem! Andrew Wakefield is alleged, based on strong evidence, to have falsified his data alleging a link between the MMR vaccine and “autistic enterocolitis”? Fuggedabouddit! The anti-vaccine movement simply pivoted neatly, de-emphasized points that the evidence was so clearly against that even they couldn’t spin it to a positive anymore, and found new bogeymen. These days, it’s the “toxins” (such as formaldehyde and the latest antivax bogeyman, squalene), and “too many too soon” (a gambit given seeming respectability by Dr. Bob Sears and Dr. Jay Gordon, apologists for and supplicants to the anti-vaccine movement both.

However, there is one trait of the anti-vaccine movement that, however its camouflaging plumage may evolve, never, ever changes. It is as immutable as believers say that God is. That trait is that, whatever other claims, the anti-vaccine movement makes, at its core it is always about the vaccines. Always. No matter how often science fails to find a link between vaccines and autism or vaccines and whatever other horreur du jour the anti-vaccine movement tries to pin on vaccines, no matter how many studies do not support the viewpoint that vaccines cause autism, no matter how much the anti-vaccine movement tries to deny and obfuscate by saying that it is not “anti-vaccine” but rather “pro-safe vaccine,” at its core the anti-vaccine movement is about fear and loathing of vaccines. Always. When inconvenient science doesn’t support their views, anti-vaccine activists either ignore the science, distort the science, or launch ad hominems against the people doing the science or citing the science. And, as I said before, the claims of the anti-vaccine movement evolve. Never again will the anti-vaccine movement make the horrific mistake of yoking itself to a hypothesis that is as easily testable as the hypothesis that mercury in vaccines causes autism. The claim that mercury in vaccines causes autism predicted that, if thimerosal were removed from vaccines or reduced to pre-”epidemic levels” of the early 1990s, then autism rates should plummet. Thimerosal was removed from nearly all childhood vaccines (the sole exception being some flu vaccines), reducing infant mercury exposure from vaccines to levels not seen since the 1980s; yet autism rates continue to rise. This is about as resounding a refutation of the hypothesis that mercury in vaccines is a major cause or contributor to autism that even the anti-vaccine movement has backed away from the pure claim, which has now evolved to unnamed “environmental toxins,” either in concert with mercury or with other nasty things, as being the Real One True Cause of Autism.

It’s evolution in action. These new claims are much “fitter” because they are much harder to falsify through scientific research, epidemiology, and clinical trials.

A Defense of Childhood Influenza Vaccination and Squalene-Containing Adjuvants; Joseph Mercola’s “Dirty Little Secret”

Fall is around the corner, and with it comes the influenza season.  Each year an average of 200,000 people in the US are hospitalized with influenza, and 36,000 die.1,2 With the addition of the novel H1N1 strain (swine flu), this season promises to be more interesting, and even less predictable, than most.  There can be no doubt, however, that this one set of viruses will exact a heavy toll for thousands of families this season.

Too often in medicine we find ourselves confronted with problems we cannot fix.  Some traumas are too severe, some infections have too much of a head start.  Some diseases are poorly understood, while others have no known treatment.  One of the darker adages of medicine still holds true: In spite of all our advances, the world mortality rate seems to be holding quite steady at 100%.

Thankfully, influenza is not a disease against which we are helpless. We have ways to limit its spread, and medicines with a modest effect in assuaging symptoms and shortening the length of illness.  Most importantly, we have vaccines that can safely prevent the disease altogether.

There are myriad misconceptions and fears surrounding the influenza and its vaccines, most are not new and have been addressed elsewhere, including the concern that the influenza vaccines cause the flu (they don’t), that the thimerosal they contain causes autism (it doesn’t), and that it can trigger Guillan Barre Syndrome (it can3, at a rate of 1/1,000,000, similar to the background rate of Guillan Barre in the population4).  The confusion has been compounded by the emergence of the novel H1N1 pandemic.  With so much at stake, it is exceedingly important to have clear, accurate information available to physicians and the public alike.

New SBM Resource – and a Word on Vaccines

We frequently receive requests from readers, our colleagues in medicine or fellow science bloggers for the best reference site that has all the information they need on a specific topic. There are many excellent resources on the net, but nothing I know of that quite puts it all together in that way – one-stop shopping for up-to-date information on the topics we are most concerned with.

So we decided to create just such a resource.

You will now see at the top of this page a new link for SBM Topic-Based Reference which leads to our new section by that name. There you will see the list of topics we are currently working on, and once they are complete more will be added. As of today only one topic is reasonably complete, Vaccines and Autism.

The format (which is subject to change as we build and use the resource) is as follows: We start with a brief topic overview. This is not meant to be a thorough discussion of the topic, but a quick summary to get people started. This is followed by an index of all SBM posts on that topic and then links to outside resources that we recommend.

Cashing In On Fear: The Danger of Dr. Sears

I generally know what’s coming next when a parent asks about altering their child’s vaccine schedule: “I was reading Dr. Sears….”

Dr. Sears is a genius. No, not in an Albert Einstein or Pablo Picasso kind of way. He’s more of an Oprah or a Madonna kind of genius. He’s a genius because he has written a book that capitalizes on the vaccine-fearing, anti-establishment mood of the zeitgeist. The book tells parents what they desperately want to hear, and that has made it an overnight success.

Dr. Robert Sears is perhaps one of the best-known pediatricians in the country. The youngest son of Dr. Bill Sears, the prolific parent book writer and creator of AskDrSears.com, Dr. Bob has become the bane of many a pediatrician’s existence. He has contributed to his family dynasty by co-authoring several books, adding content to the family website, and making myriad TV appearances to offer his sage advice. But Dr. Bob is best known for his best-selling The Vaccine Book: Making the Right Decision for your Child. This book, or at least notes from it, now accompanies many confused and concerned parents to the pediatrician’s office. Parents who have been misled by the onslaught of vaccine misinformation and fear-mongering feel comforted and supported by the advice of Dr. Sears, who assures parents that there is a safer, more sensible way to vaccinate. He wants parents to make their own “informed” decisions about whether or how to proceed with vaccinating their children, making sure to let them know that if they do choose to vaccinate, he knows the safest way to do it. And for $13.99 (paperback), he’ll share it with them.

In the final chapter of his book (entitled “What should you do now?”), after reinforcing the common vaccine myths of the day, Dr. Sears presents his readers with “Dr. Bob’s Alternative Vaccine Schedule.” He places this side-by-side with the schedule recommended by the American Academy of Pediatrics and the CDC’s Advisory Committee on Immunization Practices. He then explains why his schedule is a safer choice for parents who chose to vaccinate their children. Without a doubt, the alternative vaccine schedule is among the more damaging aspects of this book. It’s the part that gets brought along to the pediatrician’s office and presented as the the plan going forward for many parents today. But the book is also dangerous in the way in which it validates the pervasive myths that are currently scaring parents into making ill-informed decisions for their children. Dr. Sears discusses these now common parental concerns, but instead of countering them with sound science, he lets them stand on their own as valid. He points out that most doctors are ill-equipped to discuss vaccines with parents, being poorly trained in the science of vaccine risks and benefits. He then claims to be a newly self-taught vaccine expert, a laughable conceit given the degree to which he misunderstands the science he purports to have read, and in the way he downplays the true dangers of the vaccine-preventable diseases he discusses in his book. He then provides parents with what he views as rational alternatives to the recommended vaccination schedule, a schedule designed by the country’s true authorities on vaccinology, childhood infectious disease, and epidemiology.

So what does Dr. Sears have to say, exactly, about the risks of vaccines, and just how out of touch is he with medical science and epidemiology? (more…)

Vaccines and Autism: A Deadly Manufactroversy

I was recently asked to write about vaccines and autism for Skeptic magazine. I approached the project with trepidation. So much has been written, from Paul Offit’s book Autism’s False Prophets to a veritable flood of blogorrhea on the Internet. I didn’t have anything new to add, and I couldn’t hope to cover all aspects of the subject.

After some thought, I realized I could contribute something useful. I could organize the highlights into a concise and accessible story. While it awaits publication in the magazine, Michael Shermer elected to pre-publish it in the e-Skeptic newsletter. You can read it here.
