Lobbying for Quackery

The American Association of Naturopathic Physicians is lobbying Congress to pay naturopaths to treat vetarans, specifically for chronic pain. This, of course, goes beyond “health care freedom” (which itself is dubious) and is asking for taxpayer dollars to be spent on unproven and pseudoscientific treatments.

The open letter does not mention specific treatments that naturopaths would offer.  Instead it fearmongers about pharmacological treatments for pain. It is certainly true that opiates are a double-edged sword. They are powerful pain killers, but long term use causes dependence, tolerance, and may complicate pain management. Science-based physicians are well aware of this, and use a variety of approaches to minimize opiate use for chronic pain.

The letter claims that naturopaths have unique “natural” therapies that can effectively treat pain. This is one of the core myths of “alternative” medicine – if there were a treatment that objectively worked, it would be incorporated into mainstream medicine.

Thinking Style and Paranormal Belief

One burning question that comes up in skeptical circles is whether or not people who believe in the paranormal, are highly religious, or are enamored of conspiracy theories think differently than skeptics. Obviously they have different beliefs, but the question is whether or not their brains function differently in some respects from people who are more rational and scientific.

It certainly seems as if this is the case, but being skeptics we understand the irony of relying on intuition to conclude that other people rely more on intuition. Fortunately we have some psychological research to shed light on this question, including a recent study I will discuss below.

First let me dispense with the obvious false dichotomy – we should not think of this question as if there are two distinct types of people. Psychological studies will often do this, but they are simply dividing a continuum down the middle, or are only considering people at either end of the spectrum.

The Reproducibility Problem

Published by under General Science

A recent massive study attempting to replicate 100 published studies in psychology has been getting a lot of attention, deservedly so. Much of the coverage has been fairly good, actually – probably because the results are rather wonky. Many have been quick to point out that “science isn’t broken” while others ask, “is science broken?”

While many, including the authors, express surprise at the results of the study, I was not surprised at all. The results support what I have been saying in this blog and at SBM for years – we need to take replication more seriously.

Here are the results of the study:

We conducted replications of 100 experimental and correlational studies published in three psychology journals using high-powered designs and original materials when available. Replication effects (Mr = .197, SD = .257) were half the magnitude of original effects (Mr = .403, SD = .188), representing a substantial decline. Ninety-seven percent of original studies had significant results (p < .05). Thirty-six percent of replications had significant results; 47% of original effect sizes were in the 95% confidence interval of the replication effect size; 39% of effects were subjectively rated to have replicated the original result; and, if no bias in original results is assumed, combining original and replication results left 68% with significant effects. Correlational tests suggest that replication success was better predicted by the strength of original evidence than by characteristics of the original and replication teams.

FTC Responds to FDA on Homeopathy

The FDA (Food and Drug Administration) recently asked for public comment on its regulatory policies regarding homeopathy. They probably didn’t figure that a fellow federal agency, the FTC (Federal Trade Commission) would respond.

The FTC also recently asked for public comment on how it can better regulate homeopathic product advertising. While the FDA regulates food and drugs (including supplements), the FTC regulates claims that sellers can make about those foods and drugs. The FTC is now complaining to the FDA that their policies are in inherent conflict. They write:

The staff comment notes that the FDA’s regulatory framework for homeopathic drugs, set forth in a 1988 Compliance Policy Guide, does not require that over-the-counter (OTC) homeopathic drugs be approved by FDA as safe and effective if they satisfy certain conditions, including that the product’s label contains an indication for use. Yet the policy guide does not require sellers to have competent and reliable scientific evidence to support the indication for use.

The comment states that given the FTC’s long-standing advertising substantiation policy that health claims must be substantiated by such evidence the FDA’s current regulatory framework may harm consumers and confuse advertisers.

The New Seralini Study

Published by under General Science

Seralini, author of the infamous study alleging to show increased rates of tumors in rats fed GM food, the one that was retracted by the journal and then later republished in a separate journal, has published another controversial study.

The study, published in PLOSone, looks at the feed that is fed to lab rodents, the kinds used in GM research. They found:

All diets were contaminated with pesticides (1-6 out of 262 measured), heavy metals (2-3 out of 4, mostly lead and cadmium), PCDD/Fs (1-13 out of 17) and PCBs (5-15 out of 18). Out of 22 GMOs tested for, Roundup-tolerant GMOs were the most frequently detected, constituting up to 48% of the diet.

The implication is that all prior research looking at GMO and pesticide toxicity is now called into question because the control rodents would also have been fed a diet that contains some GMO, pesticides, and also heavy metal contaminants. The concept here is valid – control groups need to be proper controls. If you are testing the effects of a pesticide on rats, and the control rats are also getting the pesticide in their food, then the comparison is compromised. This would dilute out the effects of the test substance by increasing the background rate of tumors and other negative outcomes, the “noise” in the study. This would further mean that studies would have to be more powerful (contain more subjects in each group) in order to detect the diluted signal.

Drinking the “Integrative” Kool-Aid at the Atlantic

A recent article at the Atlantic by Jennie Rothenberg Gritzi demonstrates just how thoroughly the alternative medicine movement (I will refer to this as CAM) has been able to influence the cultural conversation over the practice of medicine.  This is great evidence of how successful a persistent marketing campaign can be.

Gritzi relates early on in the article that she was predisposed to CAM from a young age, which might explain her journalistic failures in this piece.  She writes:

After visiting the NIH center and talking to leading integrative physicians, I can say pretty definitively that integrative health is not just another name for alternative medicine.

Are We Seeing the End of Homeopathy?

Several years ago, during a lecture on Science-Based Medicine, I noted that if there were one medical pseudoscience that was vulnerable to extinction it was homeopathy. Homeopathy is perhaps the most obviously absurd medical pseudoscience. It is also widely studied, and has been clearly shown to not work. Further, there is a huge gap in the public understanding of what homeopathy is; it therefore seems plausible that the popularity of homeopathy can take a huge hit just by telling the public what it actually is.

Further, homeopathy is in a precarious regulatory position. Homeopathic products are presented and regulated as drugs, but clearly they are not, and they are also not supplements, herbal drugs, nutrition-based, or natural products. They are simply fraudulent drugs riding a wave of ignorance.

In the last few years homeopathy has had a rough time. While the industry is still growing, there are signs of clear trouble on the horizon. Let’s review:

Some Background

Homeopathy is a 200 year old pre-scientific system of medicine based upon magical thinking. It is mostly based on two notions, the first of which is that like cures like. In other words, a substance that causes a symptom can cure that symptom in extremely low doses. There is no scientific basis for this, despite the desperate attempts by homeopaths to invoke vaccine-like analogies, or their new favorite, hormesis.

Allergy and Other Health Scams

Allergies are a real problem, and for some people are life-threatening. Allergies also appear to be on the rise in developing countries, and scientists are not sure why.

Meanwhile, charlatans are exploiting fears of allergies and making bogus allergy diagnoses based upon bogus tests. Sense about Science recently published an excellent guide for the consumer to help make sense of what is real and what is fake when it comes to allergies. It is getting increasingly difficult for the consumer, as regulations increasingly fail to maintain a single science-based standard of care in medicine.

Narrative-Based Medicine vs Science-Based Medicine

Fake allergy diagnoses is just one manifestation of what might be called “narrative-based medicine.” I am seeing this phenomenon increasingly, both in my office as patients tell me their tales of their diagnostic misadventures, and as part of my science-based medicine (SBM) activism. The problem is that it takes a genuine dedication to, and thorough understanding of, science-based medicine in order to avoid falling into the trap of confirming your own compelling narrative. There is no sharp demarcation line, but there are examples at the extremes.

The Meddling Prince

Context is important. If a celebrity promotes a good cause, such as Michael J. Fox raising awareness about Parkinson’s disease, then that is considered altruism and charity. If, however, they promote something with which you disagree, then they are exploiting their celebrity.

I find this analogous to many legal and political claims. In the legal context, if you can’t win on the merits, then argue the law. In politics, if you oppose a law then you can challenge it based on state’s rights or as a constitutional purist. I am not opposed to these concepts – I just want to point out that often such arguments are used selectively when it is really the substance that is unwanted.

I am not decrying the use of celebrity itself. Celebrities have a right to advocate for whatever they want, and their celebrity will lend power to their advocacy. I do think that in general the public should not give weight to celebrity itself. They should be, in fact, more skeptical if celebrity is being used to support a claim. I also respect celebrities who use their power for good, and I am free to publicly criticize those who use it for “evil.” Indulge me while I engage in the latter.

Homeopathic Rant

Every now and then we get a public peek into the mind of a crank or pseudoscientist. This is not to say that they don’t utter complete nonsense often, but usually in public they try to put a sanitized and rational face on their quackery. An unfiltered rant can be refreshing and illuminating.

Recently a homeopath, Mary English, wrote such a public rant against Simon Singh, who is a science communicator and promoter of rationality. What has English so riled is the fact that Singh is threatening to sue the National Health Service (NHS) for wasting taxpayer money by funding homeopathy.

Singh is an open critic of so-called alternative medicine. He has written about homeopathy before, explaining why it is complete unscientific lunacy. He famously was sued by the British Chiropractic Association for daring to say that they embrace “bogus” therapies (because they do).  He works for a charity, the Good Thinking Society, which has challenged the UK powers-that-be to reconsider their support of homeopathy:

In February 2015, The Good Thinking Society, working with Bindmans LLP, wrote to Liverpool CCG (Clinical Commissioning Group) in order to highlight and challenge the CCG’s decision to approve spending on homeopathic treatments – a decision we believe to be unlawful, and contrary to the best interest of local patients. In April 2015, Liverpool CCG conceded our challenge and agreed to make a fresh decision on the issue.
