Quackery Red Flags

Beware the 3 D’s of quackery: Dubious, Dangerous and Distracting treatments for aches and pains (or anything else)

Picture of red flags, symbolizing the red flags that indicate quackery.

I have been studying and weighing the pros and cons of treatments for many years now — every imaginable way of helping all kinds of pain problems and chronic injuries. Always, the most important question to ask is, Does it work? But that can be hard to answer … and there are some other reasonable questions. The choice boils down to the same handful of priorities over and over again: even if it isn’t proven, does it at least make sense? Is it safe? Cheap? Reasonably convenient?

Many unproven treatments get a pass this way: they might not work any miracles, but they are still effective, safe, and/or cheap enough to be “worth a shot.”

And then there’s the ones that probably aren’t …

Treatment trouble illustrated

Many treatments are quite dubious (implausible), or particularly distracting (time consuming, costly), or somewhat dangerous… or even all of the above. This Venn diagram illustrates the intersection of these considerations.

Pain is often a tough problem, and there are no perfect treatments for it. The diagram aims to illustrate the concerns that we should juggle — not just knock everything.

The worst possible treatment would score strongly on all three Ds. Fortunately no common pain treatments are quite that bad, but my examples all have problems — at least two Ds, to some degree — that are often denied or ignored by the people selling and using them. And yet many of them are widely available, popular, packaged and promoted attractively and aggressively.1 And many of them come from giant, greedy industries. Supplements, for instance, are nearly as big an industry as pharmaceuticals, amazingly unregulated,2 and with shockingly few reputable sources of information about them. Make no mistake: selling false hope is big business.

Implausible & disproven, or just really underwhelming

Dubious treatments require your mind to be so open that your brains fall out. Some may be hopelessly at odds with solid science or even logic. Or they may be too good to be true, supposedly good for “all pain” and other delusions of grandeur. Many started out as “a good idea at the time,” but have simply not panned out — either don’t work at all, or not well enough to take seriously.3

Classic examples of implausible treatment

The most implausible therapies are detox scams and homeopathy,4 and the ultimate in disproven therapies are a lot of popular supplements5 and acupuncture (more about needles below).

Risks of harm to body & mind

When people innocently ask “what’s the harm?” there are usually answers they’ve never thought about.6 “Natural” is not always good, and often it isn’t even safe.7 By definition, anything that actually has any effect can also have too much of an effect, and some treatments are just inherently more hazardous. Bizarrely, history is actually packed with examples of popular but extremely dangerous treatments.8 There are also serious underestimated risks in the delicate business of treating chronic pain — pain-wracked nervous systems may respond very poorly to “intense” therapies and fear and worry.9

Classic examples of harmful quackery

A variety of unusually intense manual therapies, such as high velocity spinal adjustments or really strong massage, like old-school Rolfing and other “deep” styles. Many medications involve well-known and significant risks, of course.

Proper care neglected due to time & money spent elsewhere

Distraction is another kind of danger, but I set it apart because it’s the one people tend to forget about, and it encompasses a wide range of non-medical hazards, particularly the hazard to your wallet and your schedule. People will tell me they’ve “tried everything,” but when we break it down it turns out they’ve really only made an investment in, say, five things — three of them were expensive, dangerous and/or dubious, while the fourth actually interfered with the only good choice of the bunch, leaving the patient broke, frustrated, in more pain than ever, and believing that their problem is too difficult to treat. This is a bad situation — and tragically common. “Distraction” can be serious, even lethal.10opportunity cost11 is regarded by anti-quackery activists as the main non-obvious reason why alternative medicine is not “harmless.”

Classic examples of distractions from proper care

Strengthening is common distraction,12 one of the more common forms of the wild goose chase to achieve postural and structural correctness — often taking a great deal of time and money that could have been much better spent.13 Stretching is another time-consuming and mostly useless approach to fixing pain problems.14 Chiropractors are legendary for selling long, expensive treatment plans.15

Vintage “electric bath”

A triple threat: dangerous, distracting & dubious! Source: olden times.

About the (imperfect) examples in the diagram

Each example represents a particularly strong combination of two of the three D’s. It’s not an exact science.

Not all of the examples are condemned as entirely useless — such treatments would belong at the heart of the diagram! I deliberately chose not to include examples that probably do belong there, because the diagram is not the answer, but the importance of the question.

  3. It is common for dubious therapies to claim scientific support based on scientific studies that technically had statistically significant (real) “positive” results — but when you look at the data you find evidence of an effect so trivial that the therapy is damned with faint praise. It fails to impress. See The “Impress Me” Test: Most controversial and alternative therapies are fighting over scraps of “positive” scientific evidence that damn them with faint praise.
  4. Homeopathic (diluted) arnica creams for pain, such as Traumeel, are quite popular. They contain only trace amounts of the best-known ingredient, arnica. They may contain other herbs as well, some of them less extremely diluted. Scientific evidence so far strongly suggests that effects of such creams are minor at best.

  6. What’s the Harm? (

    Alternative health care has an undeserved reputation for being harmless and wholesome. In fact alternative medicines and treatments are just as full of hazards and risks as medical care, yet with virtually no proof of efficacy or regulation. While many other skeptical websites focus on the question of efficacy, is devoted to cataloguing the costs of alternative health care: the many lives ruined and even lost.

  7. Toxic contamination of barely regulated “natural” supplements is a huge problem. Marketplace exposed high levels of fecal contamination in the popular cold remedy, Cold FX: see What FX? Several studies have found outrageous levels of heavy metals in such products. Saper et al (2004) and Saper et al (2008) are good examples. See also Garvey et al and Bogusz et al.
  8. The colorful history of medicine and quackery is overflowing with people who “swore by” treatments that were bizarre and dangerous. Bloodletting was popular almost until the 20th century, despite being relentlessly harmful. Some of the most lethal “cures” in history were inspired by the discovery of radiation. People happily drank metals like mercury and silver. Even drinking urine had near fad status for a while! They tried to purge disease with sulfuric acid, and stimulate their vitality (and virility) with powerful electric shocks. Women were sold Lysol as a douche … and women actually went along with it for a while. Voluntary lobotomy may be the craziest of them all: it was a popular treatment for all kinds of psychiatric disorders, and at least fifty thousand people volunteered to have their brains lanced.

    All of these terrible treatments, and many more obscure examples, had many fans and enthusiastic testimonials. People paid for them, believed in them, loved them, swore by them — that is how misleading testimonials can be. People believe what they want to believe.

  9. Since many dubious therapies are based on trumped up pathologization tactics, all too many pain patients end up believing that they are a “really bad case” — all the more so when hard-sold therapy fails. This can make them heart-breakingly harder to treat.

  10. The classic example of literally lethal distraction is that cancer patients sometimes pursue poor alternative therapies while their cancer continues to grow, as in the much-publicized example of Steve Jobs. It’s unclear whether Jobs’s delay really increased his risk, given that he had an unusual and slow cancer. But certainly other patients have died horribly because they wasted their time on quack cancer cures that never had any promise.

  12. Weakness is rarely the cause of musculoskeletal trouble, but overuse sure is! Well-planned rest is an extremely important recovery strategy that is almost always given short shrift in favour of time-consuming efforts to get stronger, often with a “no pain, no gain” sensibility that does more harm than good. See The Art of Rest: The finer points of resting strategy when recovering from injury and chronic pain (hint: it’s a bit trickier than you might think).
  13. “Structuralism” is the excessive focus on causes of pain like crookedness and biomechanical problems. It’s an old and inadequate view of how pain works, but it persists because it offers comforting, marketable simplicity that is the mainstay of entire styles of therapy.

  14. Stretching is just generally over-rated. It certainly does feel good, but it’s ineffective for pretty much everything it is normally used for. See Quite a Stretch: Stretching science has shown that this extremely popular form of exercise has almost no measurable benefits.

    This experiment tested the effect of ibuprofen on hard-core marathoners. There were 29 ultra-marathoners on high doses of ibuprofen and 25 controls that completed the race without meds. There was no measurable difference in muscle damage or soreness between the two groups. Lead researcher David Niemen: “There is absolutely no reason for runners to be using ibuprofen.”
