The Pharma Shill Gambit and Other Nonsense

Those of us who have been writing about science and medicine for a few years or more quickly experience the fact that there is a subculture of people who are greatly hostile to our message. In addition, they tend to use the same fallacious arguments against us over and over again, as if they are reading from the same script.

As a result we answer the same bad arguments repeatedly, at least so that those who are paying attention will be more prepared to deal with such arguments themselves. Earlier this week Harriet Hall wrote an excellent post over at Science-Based Medicine in which she answers 30 common fallacious arguments against SBM.  The next day I received a comment here that parroted some of the same arguments yet again.

I have addressed these common anti-SBM arguments multiple times, mostly in piecemeal, so it’s good to have Harriet’s post as a sort-of SBM FAQ. Before you leave a critical comment, read the FAQ.

Misinformation from Mayo Clinic

The Mayo Clinic is a recognized center for excellence in both clinical medicine and research. They also maintain one of the best medical information websites on the net. I often find myself there when searching for information on a topic with which I am not familiar.

The Mayo Clinic also represents the current problem with academic medicine and the current fad of so-called complementary and alternative medicine (CAM) – they just don’t get it. They do not seem to understand what CAM really is, its history,  its current practice, and the state of the evidence. But they know it’s out there and people are interested in it (because they are told they should be) and so they feel the need to address it.

When they do address CAM, however, they have apparently done what most academic centers have done in my experience – they turn it over to “CAM experts,” which ends up being CAM proponents. The result is that CAM propaganda and shameless promotion becomes endorsed by an academic institution (what my colleagues and I have come to call “quackademic medicine”).

Health Canada Misses the Point

This is an unintended follow up to my post yesterday about holding the line against pseudoscience – this time with regard to regulations. It is one thing to lend an organization’s reputation to pseudoscience, and another when outright unscientific practices are given official sanction by a government or regulatory body. It continues to amaze me how naive (or perhaps it’s just politically expedient) such regulators can be.

On September 6th Nathan Kunzler and Arthur Caplan published an excellent editorial in The Star in which they called out Canada’s public health agency for hypocrisy. They pointed out that, according to Health Canada’s own website:

“To be licensed in Canada, natural health products must be safe, effective, of high quality and carry detailed label information to let people make safe and informed choices.”

Therefore, if they license a product they are proclaiming it safe and effective. Health Canada licenses homeopathic products, which are not effective. They are nothing but placebos, magic potions based on prescientific notions and with “active ingredients” that are often diluted beyond the point where any original substance is likely to remain. Homeopathic products are therefore literally nothing. Further, clinical trials have consistently shown that they do not, in fact, work.

A Homeopathy Debate

On two occasions I was invited to UCONN to debate the scientific legitimacy of homeopathy - in 2007, and again in March of this year. I often directly confront or debate those who hold an unscientific belief. Sometimes this is criticized as being pointless, but that claim is premised on the assumption that the only point to such a debate is convincing the person on the other side, but that is not the case.

I have several goals in direct confrontation: to better understand the claims and logic of those holding that view, to explore my own position and improve my ability to explain it, and to demonstrate scientific and critical thinking with respect to this issue to the audience.

The more recent homeopathy debate was between me an Andre Saine, a Canadian naturopath and homeopath. During the debate we barely scratched the surface of this complex topic, so we both agreed to continue our discussion in writing, moderated by Peter Gold who organized the debate.

Here is Andre’s first question to me, and my answer.

The Younger Dryas

Published by under General Science

I love raging scientific controversies. I am not talking about vaccines and autism, global warming, evolution, or homeopathy – these are not actual scientific controversies. They are political controversies intruding onto science.

I prefer nerdy scientific debates that have insignificant political implications. I like to see two groups of scientists arguing about the evidence over some narrow scientific question.  That way you get pure science without all the distortion and nonsense of politics and ideology. That is when you see how science really works.

Take for example the Younger Dryas. The last glacial maximum ended about 20,000 years ago. That glacial period was followed by interstadial (warm) periods and stadial (cold) periods. The term Dryas refers to the indicator genus (Dryas octopetali) which is a tundra flower that was much more widely distributed during cold periods. Its pollen in core samples is therefore a good indicator of an stadial period.

Imagine applying for a job, a position you really want and feel is a good match for your skills, and during the interview process you are seated in front of a psychic. The psychic is wearing full regalia, with a turban, crystals, and mystical garb. They proceed to give you a psychic reading – a reading which will be used to decide whether or not you will be hired for your dream job.

You can substitute any number of techniques for the psychic reading – a tarot card reading, palm reading, astrological chart, or phrenological analysis. Would you feel comfortable with such techniques deciding your fate? Would you feel outraged?

That is exactly what is happening in many corporations today, particularly in France. The technique that is being used, however, is graphology. It is as legitimate as any cold-reading technique (that is, not at all) but retains a veneer of scientific legitimacy. Graphology, or handwriting analysis, is a psychic cold-reading dressed up for the corporate world.

Predicting the Future

An Iranian inventor claims to have created a machine that can predict an individual’s future 5-8 years in advance. Ali Razeghi claims to have registered “The Aryayek Time Traveling Machine” with the state-run Centre for Strategic Inventions, but the Iranian government denies this.

Details are, as you might suspect, sketchy. Razeghi claims his machine works by a complex “algorithm.” It sounds like it’s a machine, not just computer software. Also he claims that the machine works by simply touching the user.

Obviously this is nonsense, but stories like this (now spread far and wide by the internet) always raise the question for skeptics and scientists – how do we address scientific claims that are “impossible,” and is it even meaningful to characterize anything as impossible given the limitations of human knowledge?

Debating Homeopathy Part II

Yesterday I discussed a recent debate in which I participated at UCONN, focusing on the plausibility of homeopathy. Today I will discuss the clinical evidence, and address some of the strategies employed by my opponent in the debate, Andre Saine.

Does Homeopathy Work?

Yesterday I made the case that homeopathy is highly implausible in many ways, and after two hundred years of scientific advance this extreme implausibility has only become greater. Two centuries has apparently not been enough time for homeopaths to make their case and convince the mainstream scientific community. The only reasonable explanation for this is that homeopathy is simply not valid.

I also took the position that overall scientific plausibility must be considered when looking at any new claim – how well does it comport with existing scientific evidence? In medicine this means, when considering clinical evidence for a treatment, that evidence needs to be put into the context of the scientific plausibility of the treatment.

Debating Homeopathy Part I

Six years ago I was asked to participate in a group debate over the legitimacy of homeopathy at the University of CT (there were six speakers, three on each side). This year I was asked to participate in another homeopathy debate at UCONN, but this time one-on-one with Andre Saine ND from the Canadian Academy of Homeopathy taking the pro-homeopathy side. (I will provide a link when the video is posted online.)

While the basic facts of homeopathy have not changed in the past six years, the details and some of the specific arguments of the homeopaths have evolved, so it was good to get updated on what they are saying today. In this post I will discuss some overall patterns in the logic used to defend homeopathy and then discuss the debate over plausibility. In tomorrow’s post I will then discuss the clinical evidence, with some final overall analysis.

Believers and Skeptics

As with the last debate, the audience this time was packed with homeopaths and homeopathy proponents. When I was introduced as the president of the New England Skeptical Society, in fact, laughter erupted from the audience. But that’s alright – I like a challenge. It did not surprise me that the audience, and my opponent, were unfamiliar with basic skeptical principles. Andre, in fact, used the word “skeptic” as a pejorative throughout his presentation.

Homeopathy Debate

I have had to take a two day break from blogging to prepare for a number of presentations I have scheduled. Today I will be engaging in a debate about homeopathy at the University of Connecticut. I did this once before, in 2007. I will give you a full report after the event.

Seating is limited and requires preregistration. But if you are in the area and want to see if there are any spaces left you can e-mail peter_gold (at)
