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.

I don't know why I'm interested in this, to the point where I'm on my sixth post about it since February. I sometimes even ask myself that very question, because taking an admittedly somewhat perverse interest in the internecine feuds among antivaccinationists. Maybe it's a bit of schadenfreude.…

Since I've been on a bit of a roll with respect to acupuncture over the last week or so, I thought I'd just round out the trilogy with one more post. One myth that acupuncture apologists like to promote relentlessly is that acupuncture is completely harmless, that it almost never causes…

TAM is fast approaching, which means one thing (at least this year). I need to get my Plexiglass blinky posterior in gear in order to have my talks together in time. I spent part of yesterday doing that, but, unfortunately, I have to work today in order to help to make up for the clinic I'll be…

Here we go again. Oh, well. These things come in waves, and sometimes I have theme weeks. Right now, this week appears to be developing into a week of quackademic medicine involving dubious acupuncture studies. Yesterday, it was acupuncture for lymphedema after breast cancer surgery, a study coming…

Lymphedema is a complication of breast cancer surgery that all surgeons who do breast surgery detest. Patients, of course, detest it even more. The limb swelling that is the primary symptom of lymphedema comes about because surgery on the axillary lymph nodes (the lymph nodes under the arm) that is…

There's a general rule that whenever you see two enemies fighting with each other that you should generally just let them. Of course, some might argue, as Gandalf did about Saruman and Sauron, that the winner of the fight would emerge stronger and free of doubt, making him harder to conquer.…

A little more than a week ago, I took note of Dr. Paul Offit's new book, Do You Believe in Magic? The Sense and Nonsense of Alternative Medicine and a story in which he was featured in USA Today about the nonsense that is alternative medicine. The news story coincided with the release of Paul…

Antivaccinationists endanger public health. They deny to high heaven that that is what they do, but they are deluding themselves. Their fear mongering about vaccines, in which vaccines in general or specific ingredients are portrayed as causing autism and a wide variety of chronic diseases, despite…

I write about cancer quackery a lot, and I've been at it for over a decade. I first cut my teeth on Usenet, delving into that cesspit of unreason known as misc.health. alternative, where my eyes were opened to just the sorts of pseudoscientific and unscientific cancer treatments patients are…

Once again, real life, mainly the eternal search (i.e., groveling) for grant money to keep my lab going, interferes with unreal life. Three grant applications due the same week will do that. Hopefully this will be the last time for a while, at least until unreal life might interfere with unreal…

Every so often, real life intrudes on blogging, preventing the creation of fresh Insolence, at least Insolence of the quality that you've come to expect. This is one of those times, thanks to three grant deadlines. So enjoy this bit of Classic Insolence from back in November 2010 and be assured…

We skeptical bloggers try our best to educate our readers about science and critical thinking, in the process explaining why various forms of pseudoscience, quackery, and cranker are, well, pseudoscience, quackery, and crankery. Unfortunately, even the most heavy duty, high traffic skeptical blogs…

Every so often, I like to try to get into the mind of an antivaccine crank, a quack, or crank of another variety, because understanding what makes cranks tick (at least, as much as I can given that I'm not one) can be potentially very useful in my work trying to counter them. On the one hand, it's…

Sometimes, between blogging, a demanding day (and night) job doing surgery and science, and everything else, I embarrass myself. Sure, sometimes I embarrass myself by saying something that, in retrospect, I wish I hadn't. More often, I embarrass myself by letting things slide that I shouldn't. For…

It's been a while since I've written about MMS. You remember MMS, don't you? It's an abbreviation for "miracle mineral solution," a solution first promoted by a man who is inaptly named Jim Humble. Basically, as I've described in multiple blog posts, MMS is bleach, specifically chlorine dioxide (…

I never used to write much about genetically modified organisms (GMOs) before. I still don't do it that often. For whatever reason, it just hasn't been on my radar very much. That seems to be changing, however. It's not because I went seeking this issue out (although I must admit that I first…

I've been trying to lay off the blogging on the weekend for a long time now, and, for the most part, I've been successful, as I'm sure regular readers will have noticed. However, sometimes I just can't help but take a few minutes to note particularly entertaining or important developments. This…
June 13, 2013
Sometimes, in the course of blogging, I come across a story that I don't know what to make of. Sometimes, it's a quack or a crank taking a seemingly science-based position. Sometimes it's something out of the ordinary. Other times, it's a story that's just weird, such that I strongly suspect that…
June 13, 2013
For a long time, going back almost to the beginning of this blog eight and a half years ago, I've referred to the "bait and switch" of alternative medicine. What I mean by that is the manner in which advocates of alternative medicine—or, as they like to call it these days, "complementary and…

What's Keith Kloor got that I haven't got? What's Laura Helmuth got that I haven't got? Why won't Robert F. Kennedy, Jr. call me to complain about all the not-so-Respectful Insolence I've directed his way over the years. I mean, seriously. I spend nearly eight years criticizing his antivaccine…

It's just one more cut on the road to the proverbial death by a thousand cuts. I'm referring, unfortunately, to last week's development in the state of Colorado. Specifically, I'm referring to the Colorado legislature's truly boneheaded decision to license naturopaths, thus giving the imprimatur of…

Every so often, real life intrudes on blogging, preventing the creation of fresh Insolence, at least Insolence of the quality that you've come to expect. This is one of those times. (Yes, it's grant season.) So enjoy this bit of Classic Insolence from 2008 and be assured that I'll be back tomorrow…

[NOTE ADDENDUM.] It's been a (mostly) all Stanislaw Burzynski week. I had been thinking of finishing up with a post about something completely unrelated; that is, until people started sending me a link. Also, because I was out last night with my wife in celebration of our wedding anniversary, I…
June 6, 2013
It was a busy day yesterday, and I had less time than usual to attend to the blog, but that's OK. This random thought popped into my head after spending the last three days writing about Stanislaw Burzynski, first reviewing Eric Merola's hagiography and infomercial about him, then seeing how well…
June 5, 2013
I realize that I've been focusing on Stanislaw Burzynski the last couple of days, but it's just been one of those weeks. Between the release of Eric Merola's latest paean to the Brave Maverick Doctor and BBC Panorama's report on Burzynski and his activities, it's been an eventful week. My review of…
June 3, 2013
After yesterday's epic deconstruction of the latest propaganda-fest from everybody's favorite Leni Riefenstahl without the talent, Eric Merola, on his most admired subject, "brave maverick doctor" Stanislaw Burzynski, I needed something science-based to cleanse the rancid taste of intelligence-…
June 2, 2013
Well, I've finally seen it, and it was even worse than I had feared. One might even say that watching it was like repeatedly smacking my head into a brick wall. It felt so good when it finally stopped. I'm referring, of course, to Eric Merola's latest cinematic "effort. Ever since it was revealed…

Cancer is a bitch. Depending upon what organ is involved and what kind of cancer it is, it can be incredibly hard to cure. All too often, it is incurable, particularly when it involves the brain, pancreas, esophagus, or other organs. People wonder why, after over 40 years of a "war on cancer," we…

Robert F. Kennedy, Jr. is despicable. I just wanted to get that off my chest. (Do clear Plexiglass boxes full of multicolored blinky multicolored lights even have chests?) The reason for my outburst will become painfully apparent all too soon, but I just had to say that. There's also one other…

Not too long ago, a reader asked me about black salve, and then not too long later I saw a commenter mention black salve. It occurs to me that, in all the years I've been doing this blog and my other blog, I don't think I've ever actually written about black salve, except in passing. So I searched…
