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.

Yes, it's that time of year again. Time to get my flu shot. So that's just what I did yesterday. I decided to brave that evil, toxin-laden, mercury-infused nastiness, all in order to protect myself and my patients against influenze. As you might recall, last year, when I was off to get my flu…

I've been harshly critical of the entire concept of "integrative medicine" (IM), which has over the last few years nearly supplanted the former term used for non-science-based medicine or medicine based on prescientific ideas represented as though it were scientific medicine, "complementary and…

I've gotten into quite a few arguments over whether there is more anti-science nonsense on the right or the left lately. Actually, none of these arguments have been on the blog, mainly because I tend not to relish getting into discussions that are far more weighted towards politics than actual…

Yesterday, I came across a concept that I had never considered before (or even heard of before). In fact, it's a concept that took me by surprise. Basically, it's an application of a concept to a problem that I never considered applying the concept to before--probably with very good reason.…

People wonder why scientists involved in controversial areas are reluctant to address the public. Courtesy of our favorite band of anti-vaccine bloggers at the anti-vaccine propaganda blog Age of Autism, we see yet another reason why. Yes, AoA's resident attack poodle Jake Crosby decided to disrupt…

I concluded last week with the dismantling one of the more bizarre stories I've seen spun by the merry band of anti-vaccine propagandists over at Age of Autism. As you might recall, Mark "Not a Doctor, Not a Scientist" Blaxill had teamed with Dan "Where are the Autistic Amish?" Olmsted (or, as I…

For some reason, when it comes to so-called "complementary and alternative medicine" (CAM) therapies, acupuncture gets a pass. Homeopathy, for example, is based on ideas so inherently ridiculous that they quite properly attract the scorn of skeptics and advocates of science-based medicine…

When you've been at this blogging thing as long as I have, it's possible to be shocked at how long you find yourself commenting on the same story. As I approach the end of the seventh year of Insolence, both Respectful and not-so-Respectful, I find these "senior blogging moments" popping up from…

I've been following the anti-vaccine movement for nearly a decade now, first as a regular on the Usenet newsgroup misc.health.alternative and then, beginning almost seven years ago, blogging away. Along the way, somehow I stumbled into the role of countering the pseudoscience, misinformation, and…

Perhaps the biggest bête noire for me is the infiltration of quackademic medicine into academic medical centers; so whenever I see particularly egregious examples, it gets my fingers twitching over the keyboard, ready to lay down some not-so-Respectful Insolence. So it was last Friday when I…

We get hate mail. Or I do. True, I don't get an inordinate amount of hate mail, but I do get some. A lot of the time, it's rather boring and predictable, which is why I don't often respond to it on the blog, although sometimes against my better judgment I respond by e-mail. That happens less and…

Whenever I write about the woo that is reiki, I feel obligated to point out just what reiki is. Sure, it might be repetitive, but I hope my regular readers will indulge me. I never know when new readers will pop in, and it is necessary to do a bit of review. Basically, reiki is faith healing that…

A couple of months ago, right before TAM 9, I took note of a rather disturbing post by one of the regular bloggers on the anti-vaccine crank blog Age of Autism. Basically, the post was worrisome because in it Kent Heckenlively portrayed those who oppose anti-vaccine pseudoscience as "wicked," even…

A few days ago, Michelle Bachmann laid down napalm grade burning stupid about the HPV vaccine. Today, Funny or Die sums it up perfectly. Michele Bachmann chooses STD's - watch more funny videos The not unexpected thing is, instead of retreating under criticism, Bachmann appears to be…

"CHEMOTHERAPY KILLS!!!!" I've lost count of how many times I've come across brain-dead statements like the one above, often in all caps on websites resembling that of the Time Cube guy, quite frequently with more than one exclamation point, on the websites of "natural healers," purveyors of "…

Oh goody. Goody, goody, goody, goody, goody. As I sat down to lay down a bit of the old ultrainsolence on a hapless bit of psuedoscience, I was near despair. For whatever reason, there didn't appear to be anything new out there for me to sink my teeth into. True, when this has happened in the past…

I don't often blog about politics anymore. As I've said on more than one occasion, political bloggers are a dime a dozen. Rare is the one that interests me much. However, sometimes things happen that lead me to make an exception, except that this time it's not really an exception because it has to…

Unfortunately, I don't get to see very many movies these days. My wife and I both lead very busy lives, and with periodic spasms of grant writing, plus several new administrative responsibilities, it's just hard. Last weekend, however, a movie that I'd rather like to see came out. Unfortunately, I…

If there's one thing about anti-vaccine activists that is virtually their sine qua non, it's an utter lack of understanding of science. Actually, a more accurate description would be that it's a highly selective understanding of science. Nowhere do I find this to be the case as much as when I see…

Once again we come to another September 11. It's hard to believe that it's been ten years since that horrible day. It's become my tradition over the last few years to post this video as a reminder of what happened that day. This video was shot by Bob and Bri, who in 2001 lived in a high rise a…

ORAC NOTE: Work kept me out late last night going out to dinner with a visiting professor. Fortunately, it was actually pretty fun. Unfortunately, it kept me from cooking up a heapin' helpin' of the Insolence, either Respectful or not-so-Respectful, that my readers crave. So instead, here's a…

One aspect of "complementary and alternative medicine" (CAM) is the resurgence of practice of what has frequently been called "traditional Chinese medicine" (TCM). I've pointed out before that TCM is a prescientific system of medicine based largely on superstition and vitalism. Indeed, where…

I don't recall how many times I've said lately that I detest the term "integrative medicine." As I've pointed out time and time again, it's the preferred "successor," if you will, to the term "complementary and alternative medicine" (CAM) (at least among the woo-friendly). After all, as I've…

Sigh. Why, oh, why do news organizations do such ridiculously stupid things? In this case, the CBC decided to put up a poll regarding the chickenpox vaccine. Here's the setup: The Canadian Pediatric Society (CPS) says children should receive two doses of the chickenpox vaccine to avoid losing…

Over the weekend, I chilled out a bit, at least as far as the blog was concerned. I won't make too much of a secret of it, but thanks to the new policy of the new owners I have a decision to make. In the meantime, while I'm dithering, you, my readers, were deluging me with requests. Well, it wasn't…

This happens to be a holiday weekend. Believe it or not, sometimes even Orac needs a break from life, the universe, and every blog, particularly this one. I'll be back tomorrow. In the meantime, I realize that I've posted videos like this before (in fact, I'm sure that at some point or another I've…

One of my interests in skepticism and critical thinking has been the similarity in the fallacious arguments, approach to data, and general behavior of those who are--to put it generously--not so skeptical or scientific in their approach to life. I'm talking about believers in the paranormal, quacks…

It's one of those things that can't be repeated too many times, but homeopathy is ridiculous. In fact, so ridiculous is homeopathy that I don't usually write about it all that often. The reason is that, like homeopathic dilutions, a bit of skeptical blogging about homeopathy goes a long, long way (…

Sometimes I feel a little bit guilty when I'm writing a post deconstructing anti-vaccine nonsense, "alternative medicine" quackery, or some other form of pseudoscience. This guilt usually derives when I end up picking a target that's just too easy, a study that's just so mind-numbingly, brain-…

I detest the term "integrative medicine," which is what promoters of "alternative medicine" pivoted to call "complementary and alternative medicine" (CAM) when they decided that they needed to lose the word "alternative" altogether. After all, no longer were CAM practitioners content to have their…
