David Gorski

Orac is the nom de blog of a humble surgeon/scientist who has an ego just big enough to delude himself that someone, somewhere might actually give a rodent's posterior about his copious verbal meanderings, but just barely small enough to admit to himself that few probably will. That surgeon is otherwise known as David Gorski. That Orac has chosen his nom de blog based on a rather cranky and arrogant computer shaped like a clear box of blinking lights that he originally encountered when he became a fan of a 30 year old British SF television show whose special effects were renowned for their BBC/Doctor Who-style low budget look, but whose stories nonetheless resulted in some of the best, most innovative science fiction ever televised, should tell you nearly all that you need to know about Orac. (That, and the length of the preceding sentence.)

DISCLAIMER: The various written meanderings here are the opinions of Orac and Orac alone, written on his own time. They should never be construed as representing the opinions of any other person or entity, especially Orac's cancer center, department of surgery, medical school, or university. Also note that Orac is nonpartisan; he is more than willing to criticize the statements of anyone, regardless of of political leanings, if that anyone advocates pseudoscience or quackery. Finally, medical commentary is not to be construed in any way as medical advice.

The blog post of mine that arguably "put me on the map" in the skeptical blogosphere was my very Insolent, very sarcastic deconstruction of Robert F. Kennedy, Jr.'s deceptive pseudoscience-ridden bit of fear mongering that he called Deadly Immunity. It was originally jointly published both by Salon…

To say that the relationship that antivaccine activists have with science and fact is a tenuous, twisted one is a major understatement. Despite mountains of science that says otherwise, antivaccinationists still cling to the three core tenets of their faith, namely that (1) vaccines are ineffective…

Blog topics seem to come in waves, where I'll be stuck on more deeply examining a topic for days, only to have that topic dry up. Sometimes, you, my readers, make me aware of a topic. This is an example of the latter case. It's something I had been debating about whether to blog about because I…

I originally wasn't going to write about this particular post, but the mass shooting in San Bernardino yesterday led me to change my mind. For those of you who either aren't in the US or were somehow cut off from media for the last 18 hours or so, yesterday a heavily armed man and woman dressed in…

Of all the slick woo peddlers out there, one of the most famous (and most annoying) is Deepak Chopra. Indeed, he first attracted a bit of not-so-Respectful Insolence a mere 10 months after this blog started, when Chopra produced the first of many rants against nasty "skeptics" like me that I've…

When it comes to blogging, sometime's it's feast or famine. Some days there are more topics and stories that I'd like to blog about than I could ever get to, given that I generally only do one post per weekday, while other days I seriously think about skipping a day because there's just nothing out…

I've been blogging for nearly eleven years now—and continuously at that, with only brief breaks for vacations or when the vagaries of life and career (particularly grant deadlines) interfered with the writing impulse. It's true that I've slowed down a bit. I rarely post on weekends any more and not…

Bullying. You keep saying that word. I do not think it means what you think it means. Yes, I do so love to co-opt that famous line from The Princess Bride for my own nefarious purposes, but it's so perfect for this particular topic, which comes up every so often when I'm writing about the…

If there's one thing I've learned about the antivaccine movement over the decade-plus that I've been following and commenting on it, it's that there are many flavors of antivaccine beliefs. These range from the "loud and proud" (and, invariably, incredibly stupid) antivaccine activists who aren't…

It is an article of faith among the antivaccine movement that vaccines are degrading the health of our children, such that vaccines cause autism, asthma, diabetes, and a number of other chronic diseases. You won't have to look far on most antivaccine websites to find claims that today's children…

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,…

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…

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…

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…

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…

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…
November 13, 2015
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…

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,…

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…

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,…

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…

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…

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…

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…

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…

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…

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…

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…

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.…

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…
