Obesity Denial
It seems that for every established science there is an ideological group who is motivated to deny it. Denialism is a thriving pseudoscience and affects any issue with the slightest political or social implications. Sometimes, even easily verifiable facts can be denied, as people seem willing to make up their own facts as needed. Denialists have an easy job – to spread...
Lest We Forget: Influenza Can Be Devastating
One of our readers suggested that I review the book The Great Influenza: The Epic Story of the Deadliest Plague in History, by John M. Barry. It’s not a new book (it was published in 2004) but it is very pertinent to several of the issues that we have been discussing on this blog, especially in regards to the current anti-vaccine movement....
Freeways, autism, and correlation versus causation
I have a love-hate relationship with epidemiology. On the one hand, I love how epidemiology can look for correlations in huge sample sizes, sample sizes far larger than any that we could ever have access to in clinical trials, randomized or other. I love the ability of epidemiology to generate hypotheses that can be tested in the laboratory and then later in...
California Forbids Chinese Bloodletting
In November 2010, the California Department of Consumer Affairs (DCA) finally decided to act responsibly and forbid the prevalent practice of Chinese bloodletting by licensed acupuncturists. The practice became a concern for the DCA when allegations of unsanitary bloodletting at a California (CA) acupuncture school surfaced. The incident allegedly occurred during a “doctoral” course for licensed practitioners. The instructor was reportedly demonstrating...
Cell Phones and Behavior
Cell phones continue to be a focus of epidemiological studies and public concern, despite the fact that so far there is no compelling evidence of any health risk from cell phones. Concerns are likely to be sparked anew with the report of a study linking cell phone use to behavioral problems in children. The study, by Divan, Kheifets, Obel, and Olsen, is...
Be thankful: No anti-vaccine propaganda at the movies this weekend
It’s Thanksgiving Day here in the U.S., and, despite the crappy economy, there are still things to be thankful for. For instance, skeptical activism can still be effective. On Sunday Skepchick Elyse put out the call to Skepchick readers to complain to movie theaters that were reportedly going to be airing a public service announcement from the anti-vaccine group SafeMinds? (Actually, “public...
Vaccine Wars: the NCCAM Drops the Ball
If you go to the website of the National Center for Complementary and Alternative Medicine (NCCAM), you’ll find that one of its self-identified roles is to “provide information about CAM.” NCCAM Director Josephine Briggs is proud to assert that the website fulfills this expectation. As many readers will recall, three of your bloggers visited the NCCAM last April, after having received an...
What does “anti-vaccine” really mean?
We frequently use terms like "antivaccine," "antivax," and "antivaxxers." Critics think it's a "gotcha" to ask how we define "antivax." It's not. There are gray areas, but not so gray that the word is never appropriate.
What’s The Harm?
Any promoter of science-based medicine often faces the question – what’s the harm? What is the harm if people try treatment modalities that are not based upon good science, that are anecdotal, or provide only a placebo benefit? There are generally two premises to this question. The first is that most “alternative” placebo interventions are directly harmless. The second is that direct...
Oprah’s buddy Dr. Christiane Northrup and breast thermography: The opportunistic promotion of quackery
Dr. Christiane Northrup came to fame as Oprah Winfrey's resident women's health expert. Unfortunately, she's using that fame to promote the unproven breast cancer screening modality thermography during Breast Cancer Awareness Month.
