Ebola Pseudoscience

It is natural for there to be a certain amount of fear and uncertainty surrounding the reported outbreak of a deadly virus. The recent ebola outbreak is the worst in history, with over 800 deaths reported out of over 1,400 infections (case fatality rate so far of 57%).

Crises like these tend to bring out the best and the worst in people. Health care workers are literally risking their lives to contain this outbreak. Meanwhile, charlatans are coming out of the woodwork to exploit the crisis to spread their nonsense.

Ebola was first discovered in 1976. The virus exists in central and western Africa, and outbreaks are usually small, involving isolated villages. The virus can exist in fruit bats, which is the usual reservoir that spreads to humans. Other animals can be the vector, however, including chimpanzees, gorillas, monkeys, forest antelope and porcupines. Once a human infection occurs, however, the virus can spread from person to person.

The Clinical Evidence for Homeopathy

Dana Ullman is a notorious apologist for homeopathy. He has a reputation, at least among skeptics, for cherry picking data and making dubious arguments – whatever it takes in order to defend his beloved homeopathy. He then tops it off by accusing skeptics of being closed-minded for not accepting his drivel.

An article of his recently popped up on the Skeptic subreddit (posted by rzeczpospolita) with the challenge, “Countless scientific studies showing that homeopathy works. Or are you “skeptics” too closed minded to accept this fact?”

The article is too long to deconstruct in one blog post, so I will focus on the key claim – that clinical evidence demonstrates that homeopathy works. His primary piece of evidence is this:

Drinkable Sunscreen

Recently the Daily Mail (some like to call it the “Daily Fail”) ran an article reporting, without any critical analysis, that a company is now offering drinkable sunscreen.

At first the claim seems extraordinary, but it is not impossible. It is theoretically possible to drink a substance that becomes deposited in the skin and absorbs or reflects UV radiation providing protection. However, upon reading the details it becomes immediately apparent that the product in question is pure snake oil.

The product is Harmonized Water by Osmosis Skin Care. In fact, UV protection is just one claim among many for the harmonized water line of products. The website claims:

  • Remarkable technology that imprints frequencies (as standing waves) onto water molecules.
  • Advances in the ability to “stack” thousands of frequencies onto one molecule.
  • Revolutionary formula allows us to reverse engineer the frequencies of substances found in nature and/or the human body.
  • Newly identified frequencies that have beneficial effects on the body.

David Katz on Evidence in Medicine

David Katz is a fellow physician at Yale, and he is also a strong proponent of so-called “integrative medicine.” He has written a recent commentary at the Huff Po, defending the integrative approach. He writes:

Integrative Medicine — a fusion of conventional and “alternative” treatments — provided patients access to a wider array of options. So, for instance, if medication was ineffective for anxiety or produced intolerable side effects, options such as meditation, biofeedback, or yoga might be explored. If analgesics or anti-inflammatories failed to alleviate joint pain or produced side effects, such options as acupuncture or massage could be explored.

His basic argument is this – when we lack strongly evidence-based options, we need to explore not-so-evidence-based options, for the good of our patients. Mainstream medicine is not that evidence-based either. And – mainstream medicine relies on money-driven research, which is biased against integrative approaches.

Ernst on Homeopathy

Edzard Ernst is one of my intellectual heroes. If you are a skeptic, you need to know who he is. He began his career amenable to the claims of alternative medicine. He became the world’s first professor of complementary and alternative medicine, and set about to do the one thing that no other CAM proponent (to my knowledge) has truly ever done – he wanted to use rigorous scientific research to find out if any specific CAM modality worked. Most proponents use research to prove that CAM does work, or simply to describe how it is used or how it can best be implemented.

Throughout the publication of his more than a thousand scientific articles, Edzard became increasingly convinced that most CAM methods simply do not work. Further, he learned what happens to people who point to the scientific truth about CAM, they are vilified by true believers.

I have to admire anyone who changes their world-view significantly in the face of scientific evidence. His intellectual honesty is refreshing.

Why We Need a Skeptical Movement

Published by under Skepticism

Skeptics tend (as they should) to question everything, even the need for a movement of self-identified skeptics. It is an interesting question – what is the net cultural effect of organized scientific skepticism?

Of course, we can’t really ever know the answer to this question. There are too many moving parts. We could point to cultural trends, but this is probably the worst line of evidence. There is no way to control for skepticism as an isolated variable. We have no way of knowing what the world would be like without organized skepticism.

We can point to individuals whose lives have been changed, they believe for the better. I am heartened by every e-mail I receive from a reader or listener who says their life has been changed for the better because of skeptical outreach. Perhaps they were steered away from a career in pseudoscience, learned how to think more critically about everything, or just found a community to which they could connect.

Homeopathic Products Recalled for Containing Actual Drugs

Homeopathy is bunk. It is 100% pure unadulterated pseudoscience. That is – unless it is adulterated with actual working medicine.

The FDA recently put out a safety alert warning the public that certain homeopathic products may contain measurable amount of penicillin, enough to cause an allergic reaction in those who are sensitive:

Terra-Medica, Inc. is voluntarily recalling 56 lots of Pleo-FORT, Pleo-QUENT, Pleo-NOT, Pleo-STOLO, Pleo-NOTA-QUENT, and Pleo-EX homeopathic drug products in liquid, tablet, capsule, ointment, and suppository forms to the consumer level. FDA has determined that these products have the potential to contain penicillin or derivatives of penicillin, which may be produced during the fermentation process. In patients who are allergic to beta-lactam antibiotics, even at low levels, exposure to penicillin can result in a range of allergic reactions from mild rashes to severe and life-threatening anaphylactic reactions. See the press release for a complete listing of products affected by this recall.

One has to wonder if the company was aware that their product contained penicillin.  That’s a pretty good scam. In the US homeopathic products do not require testing or any FDA approval process. They are essentially pre-approved by law. While this is a shameful scam, at least homeopathic remedies are completely inactive – nothing but water placed on sugar pills. However, some specific products have been found to have functional levels of active ingredients, so they are not truly homeopathic. For example, some Zicam products were found to contain active levels of zinc, and was linked to anosmia (a loss of smell) in some cases.

P-Hacking and Other Statistical Sins

Published by under General Science

I love learning new terms that precisely capture important concepts. A recent article in Nature magazine by Regina Nuzzo reviews all the current woes with statistical analysis in scientific papers. I have covered most of the topics here over the years, but the Nature article in an excellent review. It also taught be a new term – P-hacking, which is essentially working the data until you reach the goal of a P-value of 0.05. .

The Problem

In a word, the big problem with the way statistical analysis is often done today is the dreaded P-value. The P-value is just one way to look at scientific data. It first assumes a specific null-hypothesis (such as, there is no correlation between these two variables) and then asks, what is the probability that the data would be at least as extreme as it is if the null-hypothesis were true? A P-value of 0.05 (a typical threshold for being considered “significant”) indicates a 5% probability that the data is due to chance, rather than a real effect.

Except – that’s not actually true. That is how most people interpret the P-value, but that is not what it says. The reason is that P-values do not consider many other important variables, like prior probability, effect size, confidence intervals, and alternative hypotheses. For example, if we ask – what is the probability of a new fresh set of data replicating the results of a study with a P-value of 0.05, we get a very different answer. Nuzzo reports:

Is There a Pseudoscience Event Horizon?

Earlier this week Massimo Pigliucci over at Rationally Speaking wrote an intriguing blog post asking whether or not there is a pseudoscience black hole – a point beyond which a pseudoscience gets sucked in and can never escape? Asked from the other direction – are there any historical examples of a pseudoscience that became legitimate, essentially turned out to be true?

I thought this was an interesting enough question to pick up the ball and explore the question further.

First, the question requires a discussion of what is pseudoscience. This is a common topic of discussion among skeptics. Any definition must contend with the demarcation problem – there is no bright line between legitimate science and pseudoscience. Rather, there is a smooth continuum, although I do think the distribution along that continuum is bimodal.

The differences between science and pseudoscience have to do with process, not subject matter. Pseudoscientists display a number of typical behaviors  (I will quickly list some of them here, but I am overdo for an updated post just on this topic):

CAM Research – Be Careful What You Wish For

Edzard Ernst is the first professor of complementary and alternative medicine (CAM). He began 20 years ago as a CAM enthusiast, and a trained homeopath, and genuinely wanted to point the critical eye of science onto CAM. Many CAM proponents claim this, but Ernst was different in a key respect – he wanted to use rigorous scientific research to find out if CAM worked, not to prove that it does.

He recently wrote about his 20 years of CAM research, and eloquently makes this point. He writes:

Unfortunately, we also had a few co-workers who, despite of our best efforts, proved to be unable of critical thinking, and more than once this created unrest, tension and trouble. When I analyse these cases in retrospect, I realise how quasi-religious belief  must inevitably get in the way of good science. If a person is deeply convinced about the value of his/her particular alternative therapy and thus decides to become a researcher in order to prove his/her point, serious problems are unavoidable.

Problems are indeed unavoidable. There is a problem with researcher bias and publication bias in medical research. Science magazine also reports on a “sting” operation in which an author submitted a hopelessly flawed paper to 304 open access journals, with more than half accepting the paper for publication. There are plenty of places to publish terrible research that proves whatever point you wish to make.
