Quackery: A Neglected Population Health and Societal Menace

Dr. Bill London is a professor of public health at Cal State LA, and editor of Consumer Health Digest. His topic was “Quackery: a neglected public health and societal menace.”
The key concept in defining the quackery he talked about is promotion – of health products, services, or practices of questionable effectiveness or validity for intended purposes. Unproven effectiveness itself does not necessarily denote quackery. Medical practitioners can responsibly try unproven therapies in certain circumstances, where better alternatives are not available. Responsible practitioners are not promoters. But Dr. London also said that true believers can be more dangerous than intentional deceivers.
He presented a hierarchy of scientific evidentiary support for medical treatments. Topped by randomized controlled trials. But he noted that it matters how well such studies are done. And lower down are “pre-clinical” studies that can provide a basis for further testing. London cautioned about the importance of having a plausible hypothesis to support such testing; if you test for something whose underlying theory is implausible, there’s a danger of false positives.
London listed varieties of “quackogenic harm.” There’s direct harm when the treatment is actually bad for the user. Indirect harm, more common, where it interferes with the person getting proper medical care. There’s financial harm – wasting money. Psychological harm of various kinds. And societal harm, eroding our foundation of shared truth.
An audience participation effort identified red flags for quackery and why people fall for it: among them, distrust of the medical/pharmaceutical establishment; fears; confusion about the natural causes and courses of illnesses; and seductive tropes like “natural,” “helping the body heal itself,” “purity,” “mind-body,” et cetera. Religion, spiritualism, mysticism, and ideologies come into play.
London cited a 1984 Congressional Committee report calling quackery a $10 billion scandal. And some other documents of similar vintage – saying that this actually shows this has been a neglected problem. Indeed, he noted that the government itself has muddied the waters, having in 1992 (responding to political pressure from Iowa Senator Tom Harkin) created an “Office of Alternative Medicine” at the National Institutes for Health; later renamed the “National Center for Complementary and Integrative Health.”
London sees this as giving undue legitimacy to what is really still quackery. With “alternative medicine” a euphemism that has achieved some cachet in the public eye. He quoted Richard Dawkins that something can’t be false in the ordinary sense but true in an “alternative” sense (as with “alternative facts.”) London said there’s only medicine.
Now there’s been a move to replace the term “alternative medicine” with “complementary medicine,” with the idea of mainstream practitioners using it together with “conventional” medicine. Which London thinks should better be termed “regular medicine.” And he particularly hates the “integrative” word here, crafted for positive associations. We don’t, he said, “integrate” fantasy with reality.
London got some pushback from attendees who accused him of a black-and-white take, and said they’d benefited from what they took to be non-conventional medicine. In response he acknowledged that regular medicine has a lot of deficiencies, especially in treating “the whole person” which, though it might sound touchy-feely [my term: FSR] is actually important. In this regard he spoke about the placebo effect, a major factor in medicine.
This was particularly relevant when he addressed questions about acupuncture and chiropractic, both raising complex questions, and which have elements that make patients feel better even if what they do may actually be medically nugatory. Regarding acupuncture, he said that in controlled studies, the tighter the controls, the smaller the actual physical impact shown. Suggesting that acupuncture is a “theatrical placebo.”
