Labels are a cognitive double-edged sword. We need to categorize the world in order to mentally capture it – labels help us organize our mental maps of the overwhelming complexity of things and to communicate with each other. But labels can also be mental prisons, when they substitute for a thorough, nuanced, or individualized assessment – when categorization becomes pigeon-holing.
We use many labels in our writings here, out of necessity, and we try to be consistent and thoughtful in how we define the labels that we use, recognizing that any sufficiently complex category will be necessarily fuzzy around the edges. We have certainly used a great deal of electrons discussing what exactly is science-based medicine, and that the label of so-called alternative medicine is really a false category, used mainly for marketing and lobbying (hence the caveat of “so-called”).
We get accused of using some labels for propaganda purposes, particularly “antivaccinationist” (often shortened to “antivaxer”). Also “denier” or “denialist”, as in germ-theory denier. Even though we often apply labels to ourselves, no one likes having an unflattering label applied to them, and so we have frequent push-back against our use of the above terms.
As with many such terms, Read more »

The discovery of various vitamins – essential micronutrients that cause disease when deficient – was one of the great advances of modern scientific medicine. This knowledge also led to several highly successful public health campaigns, such as vitamin-D supplementation to prevent rickets.
Today vitamins have a deserved reputation for being an important part of overall health. However, their reputation has gone beyond the science and taken on almost mythical proportions. Perhaps it is due to aggressive marketing from the supplement industry, perhaps recent generations have grown up being told by their parents thousands of times how important it is to take their vitamins, or eat vitamin-rich food. Culture also plays a role – Popeye eating spinach to make himself super strong is an example this pervasive message.
Regardless of the cause, the general feeling is that vitamins Read more »

Here on SBM we have frequently had cause to criticize the media for poor science reporting and for spreading misinformation. Among many other individual offenders, we have criticized Dr. Oz for promoting alternative medicine on his TV show and gullibly promoting guests who pretend to talk to the dead and pretend to heal people with carnival sideshow tricks. We tend to be negative and critical because somebody has to do it, but it’s not pleasant. For once, I have some good things to say.
The September 12 issue of TIME magazine was a Special Nutrition Issue. The cover featured pictures of food and the title “What to Eat Now: Uncovering the Myths about Food by Dr. Oz.” It devotes 7 pages to an article by him entitled “The Oz Diet: No more myths. No more fads. What you should eat — and why.” This is followed by a 5 page article by John Cloud “Nutrition in a Pill? I took 3000 supplements over five months. Here’s what happened.” Both articles have a rational, science-based perspective without any intrusions of woo-woo.
Oz on What to Eat
Oz acknowledges that the science of nutrition is not simple and that much of what we once believed has been discarded in the face of new knowledge. He debunks a number of popular misconceptions about diet. Most of what he says is consistent with scientific evidence and with mainstream diet advice. Read more »

In a comment left on my blog, Jamie Bearse, the chief operating officer of Project Zero – The Project to End Prostate Cancer, showed how quickly and deeply discussions about screening tests can devolve into ugly rhetoric. Bearse wrote:
“Your comments along with Otis Brawley’s vendetta against the PSA sentence men to die from prostate cancer testing. Shame on you. It’s important to know your score to make a proper diagnosis and decision of if and how to treat prostate cancer. Groups that create screening guidelines for cancer such as American Urological Association and National Comprehensive Cancer Network say get tested. In fact, Brawley is at odds with his own organization. ACS supports testing as well. Otis Brawley has killed more men by giving them an excuse to not be tested. Don’t follow that path just because of your own bad experience.”
I responded:
“Jamie,
My comments policy states that I will delete comments that make personal attacks. You certainly did that with your statement that the chief medical officer of the American Cancer Society “has killed” and that he has “sentenced men to die.”
Nonetheless I have posted your comment because I think it’s important for other readers to see how some pro-screening rhetoric so quickly and completely devolves into ugliness.

Several questionable sources are spreading alarms about the possible dangers of prenatal ultrasound exams (sonograms). An example is Christine Anderson’s article on the ExpertClick website. In the heading, it says she “Never Liked Ultrasound Technology.”
[She] has never been sold on the safety using Ultrasounds for checking on the fetuses of pregnant women, and for the last decade her fears have been confirmed with a series of studies pointing to possible brain damage to the babies from this technology.
Should We Believe Her?
Should we avoid ultrasounds because Anderson never liked them? Should we trust her judgment that her fears have been confirmed by studies? Who is she?
“Dr.” Christine Anderson is a pediatric chiropractor in Hollywood who believes a lot of things that are not supported by science or reason. Her website mission statement includes
We acknowledge the devastating effects of the vertebral subluxation on human health and therefore recognize that the spines of all children need to be checked soon after birth, so they may grow up healthy.
It also states that “drugs interfere… and weaken the mind, body, and spirit.” Anderson is Read more »
