NPR and the False Choice of Alternative Medicine

A recent segment on NPR is an excellent representation of some of the mischief that promotion of unscientific medical treatments can create. The title is a good summary of the problem: “To Curb Pain Without Opioids, Oregon Looks To Alternative Treatments.” The entire segment is premised around a false dichotomy, between excess use of opioids and unproven alternative treatments. It is clear...

Seneff Claims GMOs Cause Concussions

You read that headline correctly. Stephanie Seneff first came to skeptical attention when she published a study claiming that vaccines were linked to autism. She trolled through the VAERS database and, as David Gorski noted, “tortured the data until it confessed.” Last year she published a paper in which she claimed glyphosate caused autism, claims which I addressed almost a year ago....

The Alternative Medicine Racket

ReasonTV just put out a new video called, “The Alternative Medicine Racket: How the Feds Fund Quacks,” Produced and edited by Todd Krainin. The video is a documentary about the rise of alternative medicine in the US, and is a must-watch for anyone interested in the issue. The documentary does well what a good history documentary is supposed to do – put...

Helping the Paralyzed Walk

One of our primary goals at SBM is to advocate for high standards of science in medicine. This means that we spend a lot of our time discussing claims and practices that fall short of this standard. This is very useful – exploring exactly why a claim falls short is a great way to understand what the standard should be and why....

An Industry of Worthless Acupuncture Studies

Even more interesting to me than the question of whether or not acupuncture is effective for any particular symptom is the meta-question of how acupuncture proponents have managed to promote a treatment with systematically terrible scientific data. A new study provides a fresh example of this, which I will discuss below. I think the behavior of acupuncturists reflects the fact that there...

Coca-Cola Science

Science functions best when it is free from any bias or conflict of interest. All those engaged in the process should value what is actually true more than anything else. Unfortunately, there are many sources of bias in science. Researchers may want their pet theory to be supported. Journal editors want to publish research that will have a high impact. And of...

We Should Abandon the Concept of “Alternative Medicine”

In a recent editorial for the New York Times, Aaron E. Carroll argues, “Labels Like ‘Alternative Medicine’ Don’t Matter. The Science Does.” I agree with this headline thesis, but the details of his argument ironically show the harm that the so-called CAM (complementary and alternative medicine) movement has done. Carroll starts out well, essentially pointing out that the division between “conventional” and...

About that Cell Phone and Cancer Study

Recently there was another round of scaremongering headlines and articles claiming that cell phones can cause brain cancer. The Daily News wrote: “The scientists were right — your cell phone can give you cancer.” Many online news sites declared: “SHOCK STUDY: CELLPHONES CAN CAUSE CANCER,” in all caps to make sure you understand that you should be alarmed. None of the mainstream...

Placebo by Conditioning

Truly understanding placebo effects (note the plural) is critical to science-based medicine. Misconceptions about placebo effects are perhaps the common problem I encounter among otherwise-scientific professionals and science communicators. The persistence of these misconceptions is due partly to the fact that false beliefs about placebos, namely that “the” placebo effect is mainly an expectation mind-over-matter effect, is deeply embedded in the culture....

Galvanic Skin Response Pseudoscience

Selling snake oil is all about marketing, which means that a good snake oil product needs to have a great angle or a hook. Popular snake oil hooks include being “natural,” the product of ancient wisdom, or “holistic.” Perhaps my favorite snake oil marketing ploy, however, is claiming the product represents the latest cutting-edge technology. This invariably leads to humorous sciencey technobabble....
