Missing Serious Symptoms

Alternative medicine often diagnoses overconfidently while overlooking or underestimating serious symptoms

Paul Ingrahamupdated


Ominous signs and symptoms of serious disease are often overlooked, misinterpreted, and minimized by many overconfident and under-trained “professionals” in complementary and alternative medicine (CAM). Most naturopaths, chiropractors, acupuncturists and massage therapists are blinkered by bad ideas and pet theories to some degree, but some are openly contemptuous of medical knowledge and expertise and will actually challenge the correct diagnosis.1

Meanwhile, the patient’s disease develops while it might be treated — or at least not mis-treated. Missing a serious diagnosis has an extremely high “opportunity cost2distraction from appropriate medical diagnosis and treatment.

Alternative treatment gets the headlines, but alternative diagnosis is the deepeer problem

Controversies about appropriate treatment are conspicuous. There’s a lot of human drama involved in treating deadly diseases, which often involve impossible dilemmas and ethical puzzles with no right answer. The film Dallas Buyers Club is a really excellent example. And it’s always big news when celebrities make tough treatment choices: Steve Jobs initially treating his cancer with diet, or Angelina removing her breasts to prevent cancer.

But their eyes were wide open.

There is almost no drama involved in frank diagnostic failure. Failed CAM diagnosis — wrong or missing — is almost never a story. It’s less newsworthy, because no one’s really all that surprised when CAM blows a diagnosis. And so the problem is constantly overlooked and underestimated. And the only thing worse than ineffective treatment for dire health problems is to be deprived of good diagnosis in the first place. Patients may make poor choices even when they know exactly what they’re dealing with, but they’re doomed to it when the diagnosis is wrong or completely missing. The consequences are the most tragic when minor problems are missed until they become serious.

When all you have is a (plastic) hammer: ignorance and incompetence in CAM

Diagnostic failure in CAM is mostly caused by ignorance and incompetence. But ignorance is never just an absence of knowledge: it usually involves bad ideas drowning out better ones. The biggest major factor in missing diagnoses is the preoccupation with pet theories and pseudoscientific ideas, which run the gamut from weak pet theories to militant ideology and zealotry. If someone actually believes that people can have an “allergy” to electromagnetic radiation,3 then it’s all too easy to favour that diagnosis over legitimate ones. Even mainstream physical therapy is cluttered with amazingly dubious ideas.4

But it gets worse! Haughty disdain for “mainstream” medicine is common in CAM. Many practitioners are much more alternative than they are complementary: not just dismissive but contemptuous of medical knowledge and opinion, extremely uncomplimentary complementary medicine. As a result, many militantly dismiss important precepts of scientific medicine — anti-vaxxers and germ theory denialist are excellent examples of the extremes. Germ theory denialists are as nuts as flat earthers, and just as bizarrely scommon. But it takes much less to seriously warp clinical reasoning skills and sabotage diagnosis.

But medicine is so flawed!

Yes. Good diagnosis is hard. The TV show House, M.D. was unrealistic in many ways — but it effectively dramatized just how hard it can be to figure out what’s wrong with people.

Of course, physicians don’t know everything either and also have bad ideas and make mistakes — nobody’s perfect (see Medical Errors in Perspective). However, the chances of a doctor missing a scary diagnosis are much lower, especially because they have vastly more experience with much sicker people (see Chiropractor, Naturopath Training Way Less Than Doctors).

In any event, the failures of CAM are never excused by the failings of medicine: see the tu quoque fallacy.

  1. These are sweeping statements about alternative medicine, a complex opinion that needs support, but impossible to support with a few simple references. However, there are a great many independent, unrelated sources that converge on my conclusion. I have written dozens of relevant articles that zoom in on sub-topics, like the concept of “subluxation” which the chiropractic profession relies on so heavily. Another good example: there are about a dozen major myths about massage therapy, and collectively they indicate a profession that is “blinkered by bad ideas.” And there are rotten conceptual paradigms like structuralism that permeate all of medicine, mainstream and alternative alike, but which reach hit some of their most absurd extremes in CAM clinics. And so on and on.
  2. “Opportunity cost.” Accessed 2021-01-23. “In microeconomic theory, the opportunity cost, or alternative cost, of making a particular choice is the value of the most valuable choice out of those that were not taken. In other words, opportunity that will require sacrifices.” Opportunity cost is regarded by anti-quackery activists as the main non-obvious reason why alternative medicine is not “harmless.”
  3. Electrosensitivity is an alleged allergy to electromagnetic fields and radiation. It is the basis for irrational paranoia about the health effects of Wi-Fi networks, power lines, and cell phones. There’s little doubt that the afflicted are suffering from something, but it’s either an unrelated medical condition and/or psychosomatic. Electrosensitivity has been thoroughly debunked. No one with an actual energy allergy would last a day anywhere in the modern world: they’d vanish in a poof of oversensitive smoke, moths flying into a bonfire. See Electromagnetic Sensitivity Absurdity: Electrosensitivity is an imaginary, debunked energy allergy.
  4. Not all quackery is obvious — not even to skeptics. “Pseudo-quackery” appears to be mainstream, advanced, technological, “science-y,” or otherwise legit — quackery without any sign of being way out in left field. It has enough superficial plausibility to persist in the absence of evidence against it. This subtler type of snake oil is a more serious problem in musculoskeletal health care, because it hides right in the mainstream. For instance, it’s nearly synonymous with the early history of physical therapy, and remains alarmingly prevalent in that profession. So pseudo-quackery is extremely common, and generates more false hopes and wasted time, energy, money, and harm than more overt quackery, which is relatively marginalized. See Pseudo-Quackery in the Treatment of Pain: The large, dangerous grey zone between evidence-based care and overt quackery in musculoskeletal and pain medicine.
