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've been blogging a lot about California Bill AB 2109. Basically, it's a bill that was proposed as a means of addressing the increasing problem of non-medical exemptions to school vaccine mandates because religious and philosophical exemptions are too easy to obtain. Boiled down to its essence, AB…

From time to time, I tussle with various animal rights activists online. Over the summer, unfortunately the radical animal rights types, those who think that, at the very least, vandalism is perfectly acceptable in the name of their cause, some of whom think that action up to and including murder…

Every so often, I think it's worthwhile to try to use my powers (such as they are) for good. Actually, I like to think that I'm using my powers for good each and every day, but obviously there are some who disagree. In general, these people are cranks. We're talking quacks, pseudoscientists,…

There's an oft-quoted saying that's become a bit of a cliché among skeptics that goes something like this: There are two kinds of medicine: medicine that's been proven scientifically to work, and medicine that hasn't. This is then often followed up with a rhetorical question and its answer: What do…

Every so often there are articles or posts about which I want to blog that, for whatever reason, I don't get around to. I've alluded before to my observation that blogging tends to be a "feast or famine" sort of activity. Sometimes, there isn't a lot going on, and, if there's one thing I've failed…

Ideologically motivated bad science, pseudoscience, misinformation, and lies irritate me. In fact, arguably, they are the very reason I started this blog. True, over time my focus has narrowed. I used to write a lot more about creationism, more general skeptical topics, Holocaust denial, 9/11…

It's feast or famine in the ol' blogging world, and right now it's such a feast that I can't decide what to blog about. For instance, there are at least two studies and a letter that I wouldn't mind blogging about just in the latest issue of the New England Journal of Medicine alone. Then there's…

I was out late last night for a function related to my work. As a result, by the time I got home I was too tired to blog. (I know, I know, how can a Tarial-cell powered megacomputer ever get tired?) However, I did have enough time this morning before work to act on a tip I got from some of my…

As hard as it is for me to believe when I look back at it, I've been writing about the antivaccine movement now for more than seven years here on this blog and combatting it online for at least a decade now. I like to think that over the years my response has evolved somewhat. Back in the beginning…

Homeopathy is what I like to call The One Quackery To Rule Them All. Depending upon my mood, I'll use more or less of J.R.R. Tolkien's famous poem about the One Ring from The Lord of the Rings, but the point is usually made. Homeopathy is major quackery. And it is, too. On the off chance that there…

As part of my ongoing effort to make sure that I never run out of blogging material, I subscribe to a number of quack e-mail newsletters. In fact, sometimes I think I've probably overdone it. Every day, I get several notices and pleas from various wretched hives of scum and quackery, such as…

The Human Genome Project (HGP) was one of the most massive scientific undertakings in recent years and, from a basic science and technology development standpoint, one of the most productive. The data gained formed the basis of the genomic revolution. And "revolution" is the right word. A mere 12…

In common colloquial usage, there is a term known as "gaydar." Basically, it's the ability some people claim to have that allows them to identify people who are gay. Whether gaydar actually exists or not, I don't know, but I claim to have an ability that's similar. That ability is the ability to…

I sense a disturbance in the skeptical blogosphere. It is something that I half-expected, but, even so, it nonetheless somewhat surprised me when it arrived in the form of comments on my blog and e-mails from readers, fellow supporters of science-based medicine, and others asking me what I thought…

One of the overarching issues, if not the overarching issue that makes so-called "complementary and alternative medicine" (CAM)—or, as it's now more commonly called, "integrative medicine"—so problematic is prior plausibility. It's also one of the most difficult to explain to the lay public,…

Although I focus mostly on medical topics, such as vaccines, alternative medicine, and cancer quackery, I don't limit myself to such topics. True, I used to write a lot more about evolution and creationism, the paranormal, and other standard skeptical topics, but over the last couple of years I've…

On the antivaccine front, this year began with antivaccine hero Andrew Wakefield filing suit against investigative reporter Brian Deer, the BMJ, and Fiona Godlee (the editor of BMJ) for libel based on a series that Deer published in the BMJ outlining the evidence for Wakefield's scientific fraud in…

Believe it or not, after nearly eight years blogging and around five years before that cutting my skeptical teeth on that vast and wild (and now mostly deserted and fallow) wilderness that was Usenet, I have occasionally wondered whether what I'm doing is worthwhile. Sometime around 1998, after I…

I must admit, there are times when I see something that someone else has written and, in a fit of intense envy, wish very much that I had written it. This is just such a time, and Tony Ballantyne has written just such a piece. Even better, his piece, entitled If only..., was published in Nature!…

Long, long ago, seemingly in a galaxy far, far away, I first encountered quackery on the Internet. Because I am a cancer surgeon, naturally I gravitated towards cancer quackery at first. Believe it or not, it was quite some time after that before I started to take an interest in what has become a…

About a month ago, I deconstructed a typically dishonest and deceitful attempt by that Overlord of Quackery on the Internet (in my opinion, of course), Joe Mercola, to claim that the acellular pertussis vaccine doesn't work. It was a typical Mercola bit of prestidigitation that, as so much…

Over the long weekend, I came across a bunch of things that in normal times I would have blogged about, but because I was trying to chill, work a little on the yard, and also work a bit on grants, I intentionally took Monday off of blogging. As I get back into the swing of things, work-wise,…

Why is it after a three day weekend, it always feels as though I have to "catch up"? After all, it's only one day more than the average weekend, and I didn't really do anything that different. A little yard work, out to dinner, a bit of grant writing, a bit of chilling, that's it. Maybe it's…

For my international readers, it's a holiday here in the U.S. That means I plan on taking it easy, which means I've decided on doing, in essence, a "rerun." I chose this particular rerun based on my post from last Thursday. I thought that rerunning this particular post is a good reminder of what…

Here we go again. Every so often, criticism of the antivaccine movement builds to the point where it extends beyond the blogosphere to enter the national zeitgeist in a way in which people other than blogging geeks like myself start to take notice. It happened a few years ago, when washed up…

As a cancer surgeon specializing in breast cancer, I have a particular contempt for cancer quacks. In particular, that contempt smolders and occasionally bursts in to flames right here on this very blog and, to a lesser degree, elsewhere, when I see instances of such quackery applied to women with…

If there's one thing that practitioners of pseudoscientific medicine crave more than anything else, it's respectability. Believing that science-based medicine is corrupt and that their woo is as good or better, they delude themselves into thinking that they can function as well or better than…
August 27, 2012
I might as well lay it on the line right at the beginning. It's not as though it will surprise my regular readers given what I've been writing here, most recently about when Rob Schneider played the Nazi card to express his opposition to California Bill AB2109. It's a bill that does something very…
August 26, 2012
If there's one thing I've been railing about for the last few years, it's how scientific and medical studies are reported in the lay press. It seems that hardly a week passes without my having to apply a little Insolence, be it Respectful or not-so-Respectful, to some story or another, usually as a…

When I first started this blog, I had little idea of what I was in for. I thought I had some idea from having read a bunch of blogs and found role models whose blogging style I tried to emulate back in those early days, long before I developed the persona and writing style that most of my readers…
