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 written before about how animal rights cranks have started resorting to terroristic tactics in order to intimidate or frighten researchers into ceasing to do animal research. As you may guess, I have little but contempt for the Animal Liberation Front (is that anything like the People's Front…

If you think Orac's insolence doesn't live up to the name of this blog, at least when it comes to lamenting the infiltration of unscientific, non-evidence-based modalities into academic medicine, such as the use of reiki in a top academic trauma hospital, woo finding its way into the mandatory…

Amazing. I didn't actually expect this, but it appears that some knuckleheads have actually nominated Respectful Insolence again for the Best Medical/Health Issues Blog in the 2007 Weblog Awards, and, even more oddly, I somehow managed to be finalist. It turns out that P.Z. Myers is also a…

Don't forget, once again the time is fast approaching. Soon yet another installment of the Skeptics' Circle will be upon us. In fact, it's less than a week away and due to land at the Holford Watch on Thursday, November 8. Skeptical bloggers, there isn't much time left for you to get your entries…

Arguing with cranks can be an extremely frustrating experience, which is why I don't do it very often anymore except on my terms on this blog. Yes, I did cut my skeptical teeth, so to speak, for several years doing just that in the totally unmoderated and wild free-for-all known as Usenet before I…

In retrospect, I feel a little guilty about last week's edition of Your Friday Dose of Woo. As a couple of commenters pointed out, the guy responsible for the woo seems as though he's a bit disturbed, as evidenced by the ransom note-style literature on his website and the news story that mentioned…

Over the summer, I got into a bit of an argument with a certain Libertarian comic named Tim Slagle who doesn't seem to accept the scientific consensus that anthropogenic global warming is happening or that it is a potentially grave problem. In a perilous bit of criticism, given that comedy often…

Despite the diatribes that appear here on a regular basis bemoaning the unscientific and sometimes dangerous claims made for so-called "alternative medicine" modalities, I'll be among the first to admit that in some cases it's not always clear what is "alternative" about some therapies. Indeed,…

...we need a little something as night approaches. I know just the thing: Brain-eating zombies. Given that this is the blog that conceived of the misbegotten literary (if you can call it that) device known as the Hitler Zombie, how could I not post a clip involving an actual cinematic brain-eating…

Having gotten into the whole idea of blogging about peer-reviewed research yesterday and even using a spiffy new icon to denote that that's what I'm doing, originally I had planned on looking up another interesting article or pulling one from my recent reading list and blogging about it. Then,…

...at least, that was my first reaction when I first read this reaction by the Karen Malec of the Coalition on Abortion/Breast Cancer to posts by Mark Chu-Carroll and myself pointing out the numerous flaws in the latest "study" being circulated to "support" a link between abortion and breast cancer…

Dave Munger and others have been spearheading an effort to promote the acceptance of a specific logo that science bloggers (ScienceBloggers, included) can use to let the reader know that the topic of a blog post is a discussion of real, peer-reviewed research. Use of the logo, which I've used for…

Every so often, as a blogger, I get e-mail. Well, actually, I get a lot of e-mail, much of which I just don't have time to answer (nothing personal when it happens), but every so often an e-mail makes me feel as though Rod Serling should be popping up at the end. I got this one not too long ago:…

I was half-tempted to e-mail this one to P. Z. or Larry Moran, but my inherently merciful nature got the better of me. Because it was so idiotic, I was afraid that, after P. Z. and his regular readers got through with it (or even worse for this poor ID advocate, Larry Moran), there wouldn't be…

These days, pretty much everyone, smokers included, knows that smoking is bad for you. It promotes lung cancer (and several other varieties of cancer as well), heart disease, emphysema, and a number of other health problems. If you ask most smokers, they will tell you that they'd like to quit but…

...I am as appalled as my fellow ScienceBlogger Mark over this horrifically credulous article on ghosts on This Old House at CNN.com. Here's a small taste, which comes after a long discussion of how to choose a "good" ghost inspector: If natural explanations cannot be found, and it's determined…

A couple of weeks ago, I wrote about a favorite topic for amusement among general surgeons, rectal foreign bodies, particularly the strange things people like to stick up their bottoms for whatever reason. I pointed out at the time that sometimes the excuses such patients make when seeking medical…

As usual, Cectic nails it (click on comic for the full-size version): Although I find it odd that the "mark" in the above comic would be calling for his checkbook rather than his credit card, it never ceases to amaze me how skeptical some people can be when dealing with financial matters while…

Some woo is very, very complicated. The reason, of course, is that the often self-contradicting complexity of this sort of woo serves to make it harder for people without specialized training to figure out easily that it makes no sense scientifically. It's more a matter of baffling 'em with…

This has been a bad week at skeptics' school. Apparently, skeptical bloggers have been misbehaving left and right. Apparently we as the skeptical blogosphere have been very, very naughty indeed. Worse, the essays that we've handed in are apparently not pleasing to the teacher. Worst of all, we've…

As a longtime Mac head, I'm always rather amused by just how emotionally invested people become over a mere tool like an operating system for a computer. A reminder of this popped up over at Pharyngula today, when in the course of echoing a call from the Mothership for reminiscences of the…

I approach this topic with a bit of trepidation. I say this not because I'm unsure that I'm correct in my assessment of the article that I'm about to apply some Respectful Insolence⢠to. Rather, it's because the last time I brought up anything having to do with abortion, it got ugly. The topic is…

Wow, after my post about Le Canard Noir's being threatened with legal action for criticizing the Society of Homeopaths, I'm glad to know that I won't be being sued for having reposted his criticism. Whines the Society of Homeopaths: The Society of Homeopaths took the content of the 2006 BBC…

I've always wondered, as I'm sure many of my readers have, whether human beings have it in them to delay their own death, even briefly. Very early in the history of this blog, a mere 11 days after I started it, I discussed a study that strongly suggested that we cannot. In brief, it looked at the…

For those not in academic biomedical research, "PI" stands for "principal investigator"; i.e., the person who wrote the grant that funds the laboratory effort and (usually) the leader of the laboratory. Unlike Revere, I've only been a PI for around 8 years and an NIH-funded PI for only around two…

Ever wonder what would happen if mendacious fake "psychic" Sylvia Browne ever met The Amazing Randi? Now you know. Sylvia just has to watch out for science.
October 23, 2007
Regular readers know that I've long been disturbed by the increasing infiltration of non-evidence-based "alternative" medical therapies into academic medical centers (1, 2, 3, 4, 5, 6, 7, 8). I've come across another example of how much this has occurred. This time around, it's come in the form of…

A couple of weeks ago, I mentioned how Holocaust denier extraordinaire David Irving had gotten into some trouble with his former fellow travelers in the world of Holocaust denial. Apparently they didn't like the fact that he now concedes that the mass slaughter of Jews "may have" occurred. Of…

I was thinking of calling this post Jenny McCarthy and Julie Deardorff: Two crappy tastes that taste crappy together, but I've already used that joke with Jenny McCarthy and Oprah Winfrey. Besides, Julie Deardorff isn't nearly as famous as Oprah, although, as I've discussed before, she's probably…

Maybe this is the one. On the other hand, it may be more appropriate to the victims of Orac's Respectful (and not-so-Respectful) Insolenceâ¢. Maybe I'm beginning to understand this LOL cat thing after all...
