For the past 17 years Edge magazine has put an interesting question to a group of people they consider to be smart public intellectuals. This year’s question is: What Scientific Idea is Ready for Retirement? Several of the answers display, in my opinion, a hostility toward science itself. Two in particular aim their sights at science in medicine, the first by Dean Ornish, who takes issue with large randomized controlled clinical trials, and the second by Gary Klein, who has a beef with evidence-based medicine.
These responses do not come out of nowhere. The “alternative medicine” meme that has taken hold in the last few decades (a triumph of slick marketing over reason) is all about creating a double standard. There is regular medicine which needs to justify itself with rigorous science, and then there is alternative medicine, where the rules of evidence bend to the needs of the guru or snake oil salesperson.
We have been hearing arguments from alternative medicine proponents for years now for why the strict rules of science need to be relaxed or expanded. Andrew Weil has advocated for the use of “uncontrolled clinical observations,” (also known as anecdotes). David Katz advocates for a “more fluid concept of evidence.” Dr. Oz went as far as advocating outright medical relativism, saying. “You find the arguments that support your data, and it’s my fact versus your fact.” (more…)
It’s the time of year where if you’re not sick, someone you know probably is. The influenza season in the Northern hemisphere started out slowly, but seems to be accelerating and hasn’t peaked yet. Add that to cold viruses circulating, and you get the peak purchasing period for cough and cold remedies. John Snyder gave a nice summary of the evidence base for the common treatments a few weeks ago. In short, despite all the advertising, there is little evidence to suggest that most of the “tried and true” products we’ve used for decades have any effect on our symptoms. One of the most sensible developments that’s occurred over the past few years has been the discontinuation or relabeling (depending on your country) of cough and cold products for children. The rationale to pull these products is compelling: Cough and cold remedies have a long history of use, and were sold without prescriptions before current regulatory standards were in place. They were effectively grandfathered onto the marketplace. When it comes to their use in children, the data are even more limited. There are few published trials and the results are complicated by different age groups, irregular dosing, lack of placebo control, and very small patient numbers. What’s even harder to believe was that doses were based mainly on expert opinion, not data, and generally didn’t consider that children don’t handle drugs the way adults do. So why withdraw them from pediatric use, but not adult use? Like most regulation, it comes down to risk and benefit. Both are troubling for pediatric use. (more…)
Let’s conduct a little thought experiment. First, for the sake of this thought experiment let’s assume that you have no morals, ethics, or conscience. You are comfortable lying to people, even if they are sick, and even if it will harm their health.
Your task is to get as many people as possible to believe that small bits of plastic can improve their health and treat their symptoms. This is not as difficult as it may at first appear, and the payout can be huge. Small plastic stickers can be mass produced for pennies. The primary investment will be creating and maintaining a website. Then, if you can get people to believe that the plastic stickers are magical, the money will come rolling in.
What claims should we make for the stickers? Let’s stay away from anything that has an objective outcome, so we won’t claim that they can be used as an antibiotic to treat pneumonia, or as a way to treat heart attacks. I also understand that in the US and other countries, they take a close look at claims made to treat specific diseases, but you can make vague “structure function” claims with abandon, so let’s go with those. We can always imply that they are effective for diseases, even serious ones like cancer. (more…)
Here we go again. I once said that, in the wake of study after study that fails to find activity of various “complementary and alternative medicine” (CAM) beyond that of placebo, CAM advocates are now in the midst of a “rebranding” campaign in which CAM is said to work through the “power of placebo.” Personally, I’ve argued that in reality this new focus on placebo effects as the “mechanism” through which CAM “works” is in reality more a manifestation of the common fantasy that wishing makes it so.
None of this, of course, can stop everybody’s favorite apologist for “complementary and alternative medicine” (CAM) and, in particular, using placebo effects therapeutically, from continuing to do what he does with a study that’s been widely reported in the news and even featured on Science Friday last week. Basically, it’s a study in Science Translational Medicine, in which our old friend Ted Kaptchuk teamed up with an investigator interested in migraines, Rami Burstein, to do a study that finds that believing a medicine will work can have a strong effect on its actual activity on migraine. As is the case with most studies in which Kaptchuk is involved, it’s mildly interesting from a scientific standpoint. Unlike most studies in which he is involved, Kaptchuk seems a bit more able to tone down the hyperbole, which is a good thing. Unfortunately, this study, as much as it’s being touted by the press as providing new information on placebo effects, really doesn’t tell us much that is new. (more…)
Those who cannot remember the past are condemned to repeat it.
- George Santayana
Most people don’t have that willingness to break bad habits. They have a lot of excuses and they continue to produce bad clinical studies.

One is a guitar player, one is a philosopher. I get them confused.
I think George was in charge of SCAM research at the NIH. It was Dr. Gorski who first used the term Whac-a-Mole to describe what we do. The same badly-done studies are done over and over and misrepresented over and over, with only very minor variations on a theme. This is especially true of acupuncture, the most extensively studied pseudo-medicine in search of something, anything, for which it might be effective. They are still searching.
I loved going mano-a-mano with my kids when they were younger on the Whac-a-Mole machine in the Seaside arcade followed by root beer and elephant ears. It was the last time I beat either of them at any athletic endeavor. So I enjoy Whac-a-Mole, with mechanical rodents or bad research. (more…)
We are proud to announce a new organization: The Society for Science-Based Medicine.
A Society for a community of like-minded individuals, both in and out of health care, who support the goals of Science-Based Medicine.
People should not suffer, die, go bankrupt, and lose time and hope because of complementary and alternative pseudo-medicine.
One of the most commonly practiced strategies used by parents to alter long term behavior of their children is corporal punishment, commonly referred to as spanking. But use of the term spanking is problematic in that how caregivers interpret it varies widely, and there is frequent overlap with what pediatricians consider to be abuse. Despite a great deal of evidence showing that spanking is ineffective, is a risk factor for greater forms of physical abuse and can negatively impact the behavioral and cognitive development of children in a variety of ways, it remains a controversial issue in the United States. The American Academy of Pediatrics and numerous other professional organizations have come down firmly against the use of physical punishment by parents, but unlike 34 other developed nations there are no federal laws banning spanking.
Laws regarding corporal punishment vary from state to state. 19 states currently allow the striking of a child in any school setting. Of the 31 states and the District of Columbia that ban the practice in public schools, only New Jersey and Iowa also include private schools. Many schools give the misbehaving child a choice between suspension and being beaten with a paddle. It is also common for schools to require a parent to opt out of their child receiving corporal punishment rather than having to sign a consent form before such physical correction is applied. Corporal punishment in schools is more prevalent in the South and in lower socioeconomic school districts, leading to poor black children being by far the most likely to face it.
Currently no state has a law that explicitly bans corporal punishment in the home. In fact, most state laws have specific language in their statutes on abuse, assault, battery, or domestic violence that make exceptions for spanking by a caregiver. In 2012, new child abuse legislation in Delaware made the news because it might possibly be interpreted as making spanking illegal. The law was put into place to serve as a means of improving the ability to protect children from physical abuse, but the language was vague. The lawmakers claim that it is not meant to interfere with parents who choose to use “reasonable force”, whatever that means, and do not cause injury. (more…)
There’s an old joke about the doctor whose son graduates from medical school and joins his practice. After a while the son tells his father, “You know old Mrs. Jones? You’ve been treating her rash for years and she never got better. I prescribed a new steroid cream and her rash is gone!” The father responds, “You idiot! That rash put you through medical school.”
That’s a joke. It doesn’t reflect reality, but it reinforces a common misconception that doctors care more about their own income than about their patient’s outcome. That accusation is demonstrably untrue.
I’m sick and tired of all the doctor-bashing. They accuse us of being shills for Big Pharma. They say “Doctors are only out to make money.” Or “Doctors are greedy bastards only interested in the bottom line.” Or as one of our commenters recently put it: “First do no harm. Second ? Third, profit [sic]” Some have even made the ridiculous accusation that doctors have found the cure for cancer but have suppressed the information so as to keep people sick and increase their business. If profit were really their primary motivation, doctors would have to be astoundingly clueless, because they keep doing things that are guaranteed to reduce their profits. (more…)
We received the following letter:
Your blog, the SBM page, has come up for me several times in my research. I’m an RN trying to research cancer treatment, for myself, I am the patient. I’m also a licensed massage practitioner with a 30 year history using “alternative” or “complementary” medicine successfully to treat myself for various things. When your blog has come up I’ve read into it, picking up some useful information.
My question is, why the sarcasm? Why do you and the responders on your site have such disdain and anger? Why do you feel threatened? Your physician status gives you the top of the totem pole, the extensive training, the authority and the privilege. Very doubtful you are going to be knocked off the top of that totem pole in this or any several more lifetimes to come. (more…)

For those of us dedicated to supporting science-based medicine and fighting the ever-widening reach of sCAM, pseudoscience, and health fraud, finding a new woo-filled claim or a dangerous, evidence-lacking trend to write about is relatively easy. Many of us may not realize, however, that some of the most commonly used and recommended treatments, one of which at least is probably sitting in your medicine cabinet as you read this, is equally devoid of evidence to support its use.
Every drug store has row upon row of medicines designed to treat or prevent an acute upper respiratory tract infection, otherwise known as the common cold. Despite this, very few are able to live up to their promise. In most cases, particularly where children are concerned, the side effects of these medicines can be worse than the symptoms they are intended to treat. Because I am a pediatrician, and because the evidence for cough and cold medicines (I will refer to them here as CCMs) for children is particularly absent and because adverse events due to CCMs are most frequently seen in children, I will focus mainly on this population.
