As a surgeon and skeptic, I find neurosurgeon turned presidential candidate Ben Carson to be particularly troubling. I realize that I've said this before, but it's hard for me not to revisit his strange case given that the New York Times just ran a rather revealing profile of him over the weekend, part of which included Dr. Carson answering criticism for the really dumb things he's said about vaccines, evolution, and the like. People like Ben Carson are useful examples of how highly intelligent people who are incredibly competent in one area can also demonstrate unbelievable ignorance in…

One of the key principles of skepticism, particularly in medicine, is that correlation does not necessarily equal causation. I emphasize the word "necessarily" because sometimes skeptics go a bit too far and say that correlation does not equal causation. I myself used to phrase it that way for a long time. However, sometimes correlation does equal causation. However, much, if not most, of the time it does not. So how do we tell the difference between when correlation might well equal causation and when it does not? Science, of course, and critical thinking. Science is the main reason that we…

I didn't think I'd be discussing Dr. David Katz again so soon after the last time. In fact, when blog bud Mark Crislip (who clearly hates me and wants me to pop an aneurysm or have a heart attack, given how often he sends me links to articles as infuriating as this) sent me a link to Dr. Katz's latest article, "Cleaning the House of Medicine", published—where else?—in The Huffington Post, that home for "reputable" quack-friendly bloviation since 2005, when I first read the article, my first reaction was that Katz must surely be trolling supporters of science-based medicine. At first, I wasn't…

Now that's what I'm talking about! Yesterday, the Justice Department announced criminal charges and lawsuits against the sellers of several supplements! This is the ort of thing that is long overdue—incredibly so, in fact. Before I get to this specific case, let's discuss a little background. One of the regular topics I write about, both on this blog and at my not-so-super-secret other group blog, is how supplement manufacturers take advantage of the lax regulation of dietary supplements in this country. It's a problem in our laws that we've had since the supplement industry and its lapdogs…

The other day, I suddenly realized that it's been a long time since I've written about the Polish expat doctor in Houston who treats patients with advanced brain cancer with a concoction that he dubbed antineoplastons (ANPs). I'm referring, of course, to Stanislaw Burzynski who, despite the fact that he has no training in medical oncology, has treated thousands of cancer patients with ANPs beginning back in the late 1970s. Somehow, despite the fact that he's never even come close to showing that ANPs are effective and safe against the cancers for which he uses it, the FDA has, with a brief…

It's no secret that I'm not a big fan of naturopathy. It is, as my good bud Kimball Atwood has said, a prescientific system of medicine rooted in vitalism, the idea that there is a "life energy" and a "healing power of nature." Naturopaths invoke very simplistic concepts to explain the cause of disease, such as "toxins," widespread food allergies, gluten, imbalances in qi (the life force energy), and many other pseudoscientific principles. To give you an idea of the kind of pseudoscientific quackery naturopathy encompasses, consider this: You can't have naturopathy without homeopathy, which…

The question of whether it is worthwhile to debate cranks, quacks, and advocates of pseudoscience has long been a contentious issue in the skeptic community. Those of you who've been reading my posts for a while know that I've always come down on the side that it is not a good idea One thing I've learned in my more than a decade of blogging, both here and at my non-pseudonymous other blog, is that advocates of pseudoscience love public debates. Indeed, whenever you see a skeptic agree to a public debate with an advocate of pseudoscience, it's a damned sure bet that it wasn't the skeptic who…

A typical response to a charge of being antivaccine coming from someone whose rhetoric is definitely antivaccine is to clutch her pearls mightily and retort, "I'm not 'anti-vaccine.' I'm pro-vaccine safety." Similarly, a common retort of antivaccinationists who believe that vaccines cause autism, particularly those who believe that vaccines caused their children's autism, is to declare themselves "autism advocates." Indeed, the bloggers at one of the most wretched hives of scum and antivaccine quackery on the whole Internet, Age of Autism, routinely declare themselves an autism advocacy…

I've used my current pseudonym since at least the late 1990s, first on Usenet and then on the first incarnation of this blog. Not surprisingly in retrospect (although it surprised me at the time), people who didn't like me began trying back in the 1990s to "unmask" me. It began with Holocaust deniers. No, I'm not trying to Godwin this post; it really did begin with Holocaust deniers because, as longtime readers know, my "gateway drug" to skepticism was refuting the lies and misinformation of Holocaust deniers. So, round about the turn of the millennium, a group of Holocaust deniers managed to…

After nearly 11 years (!) at this blogging thing, I thought I had covered pretty much every medical topic a skeptic and supporter of science-based medicine would be interested in covering. However, if there's one thing I've learned over the years, it's that there's always something I've missed, some hole in my blogging oeuvre that needs to be filled. Perhaps when I've been at this for 20 years I'll have filled them all in. Even if that becomes true sometime in the next nine years, I will likely have only filled in the old gaps, while new ones will have formed. Dealing with pseudoscience is…

David Katz doesn't much like skeptics, particularly those of us who question the value of "integrative medicine." In fairness, I can't say that I much blame him. We have been very critical of his writings and talks over the years to my criticism of his statement advocating a "more fluid concept of evidence" more than once, to my pointing out that his arguments frequently boil down to a false dichotomy of either abandoning science or abandoning patients. Last week, my friend Jann Bellamy discussed an unfortunate special supplement of the American Journal of Preventative Medicine (AJPM)…

As a surgeon, I find Ben Carson particularly troubling. By pretty most reports, he was a skilled neurosurgeon who practiced for three decades, rising to the chief of neurosurgery at Johns Hopkins. Yet, when he ventures out of the field of neurosurgery—even out of his own medical specialty—he routinely lays down some of the dumbest howlers I've ever heard. For example, he denies evolution, but, even worse, he's been a shill for a dubious supplement company, Mannatech. Worse still, when called out for his relationship with Mannatech in the last Republican debate, Carson lied through his teeth…

I've been at this blogging thing for more than a decade now. Looking back on those years, I find it incredible that I've lasted this long. For one thing, I still marvel that there are apparently thousands of people out there who still like to read my nearly daily musings (or, as George Carlin would call them, brain droppings) after all these years. More importantly, being a public advocate for science is a rough business, as I've documented over the years. Back when I first started out, I was completely pseudonymous and anonymous. I kept my real name relatively secret. It was less than five…

Naturopathy is a cornucopia packed to the brim with virtually every quackery known to humankind, be it homeopathy, much of traditional Chinese medicine, vitamin C for cancer, or basically any other pseudoscientific or prescientific treatment for disease that you can imagine. I feel obligated to start most of my posts about naturopathy with a statement like this not just because it's true but because I want to remind my readers that it's true. I particularly want to remind my readers when I see naturopaths revealing their true quack selves when they think no one's watching, but I want to…

I hadn't planned on writing about this again today. (How many times have I started a post with that phrase? I forget, but a lot. Sadly, developments frequently make me change my plans about blogging.) Here's what made me change my plans It was a pair of Facebook posts on hip-hop and fashion mogul Russell Simmons' Facebook page. Here's post #1: And here's post #2: This, of course, is the news report regurgitating antivaccine talking points broadcast in Atlanta late last week by Ben Swann, an all-purpose conspiracy theorist and, apparently, now antivaccinationist, who is anchor for the…

Before yesterday, I had never heard of Ben Swann. Apparently he is the new anchor for the early evening news broadcast of the local Atlanta CBS affiliate, having joined the station in June. Apparently he is also prone to antivaccine conspiracy theories, which is a very bad thing to be prone to as a reporter or anyone working in the news media. I came to learn of Swann because of an article that looks on the verge of going viral (given that relatives have e-mailed me asking me about it) entitled CBS Reporter Ben Swann Tells the Truth About CDC Vaccine Cover-Up. Of course, I can't help but…

When I wrote about YouYou Tu, the Chinese scientist who won the Nobel Prize in Physiology or Medicine for her successful identification, isolation, purification, and validation of Artemisinin, an antimalarial medication that was quite effective. It was also derived from an herbal remedy used in traditional Chinese medicine (TCM), which has led a fair number of TCM advocates to portray this Nobel Prize as a "validation" or "vindication" of TCM. It wasn't. Nor was it a validation of naturopathy or herbalism, as has been claimed. It was a validation of the good, old-fashioned science-based…

Unfortunately, this happens to be a day when I didn't really have much time to blog, as I had to go to an evening meeting last night related to my work. Fortunately, this corresponds with a most excellent day, a first in my life. Basically, I'm coauthor on a Perspective article published in today's New England Journal of Medicine on trends in metastatic disease in breast cancer and prostate cancer. Even better, it's not behind a paywall (at least for now); so you—yes, you!—can read it. It's also written at a level that I think a lot of our readers will enjoy it, although the strict word…

No doubt, regular readers are probably somewhat surprised that I didn't discuss the antivaccine rally scheduled to be held in Atlanta last weekend that I wrote about last week. As you might recall, this rally consisted of two crappy tastes that taste crappy together, namely Robert F. Kennedy, Jr. and the antivaccine movement together with the Nation of Islam. Given that the Nation of Islam, besides being a truly crank religion on its own, of late has gotten very cozy with the Church of Scientology, thus amplifying the crank factor by orders of magnitude (at least). Readers not familiar with…

I'm a clinician, but I'm actually also a translational scientist. It's not uncommon for those of us in medicine involved in some combination of basic and clinical research to argue about exactly what that means. The idea is translational science is supposed to be the process of "translating" basic science discoveries into the laboratory into medicine, be it in the form of drugs, treatments, surgical procedures, laboratory tests, diagnostic tests, or anything else that physicians use to diagnose and treat human disease. Trying to straddle the two worlds, to turn discoveries in basic science…
