Hostility towards scientific consensus: A red flag identifying a crank or quack
Deniers of well-established science, such as the anthropogenic climate change, the theory of evolution, and vaccine science, frequently attack the scientific consensus. Some go farther and attack the very concept of a scientific consensus. When you see such attacks, you know you're dealing with a crank or, in the case of medicine, a quack.
Risks of CAM Treatments for Cancer
“What’s the harm?” is an insidious idea when used as a justification for unscientific medical treatments. The argument is typically put forward with the assumption that direct physical harm is the only type of harm that can result from such treatments, so as long as they aren’t toxic there is no downside to trying them. Harm comes in many forms, however: delayed...
Outcome Bias in Clinical Decision Making and the Assessment of Our Peers
There are many mental pitfalls and logical stumbling blocks faced by healthcare professionals when attempting to untangle the complex web of patient history and physical exam findings. They can impede our ability to practice high quality medicine at every step in the process, interfering with our ability to establish an accurate diagnosis and to provide comfort or cure. And we are all...
Homeopaths Threaten Public Health Selling Sugar Pills as Vaccine Alternatives
Alternative medicine is ascendant in Canada. From the dubious remedies that are now stocked by nearly every pharmacy, to the questionable “integrative” medicine at universities, there’s a serious move to embrace treatments and practices that are not backed by credible evidence. Canada’s support for alternative medicine, and for its “integration” into conventional health care is arguably is worse than many other countries....
The Central Dogma of Alternative Medicine
Steve still happens to be galavanting about Australia, spreading science, skepticism, and, of course, science-based medicine Down Under. Given that, he has been unable to produce new content for today. Never one to let such an opportunity pass, I decided to take advantage in order to do a little shameless self promotion. A week and a half ago, I gave a talk...
Announcement: The Society for Science-Based Medicine is co-sponsoring NECSS
Steve is off today, so I thought it would be a good idea to use this slot for a little shameless self-promotion (of Science-Based Medicine and the Society for Science-Based Medicine, of course). The Northeast Conference on Science & Skepticism (April 9-12, 2015 in New York City) will be bigger than ever in 2015 with fabulous presenters, exciting panels, and engaging workshops....
Selective pressures on alternative medicine
(Editor’s note: I was away at Skepticon over the weekend, where I gave a talk entitled “The Central Dogma of Alternative Medicine”. (When the talk’s up on YouTube, I’ll provide a link, of course.) Because of all the fun and travel delays I didn’t get a chance to turn my slides and notes into a blog post yet. Also, I’m on vacation...
Energy Drinks are Risky, Especially for Kids
Should children drink energy drinks? No, it's a terrible idea.
Oxygen Myths That Refuse to Die
One of my early forays into the world of pseudoscience was an investigation of “Vitamin O” (the O stands for oxygen). The story is hilarious; please click and read; I guarantee you won’t be able to read it without at least a chuckle. Vitamin O is still for sale; it’s even available on Amazon.com. You can read the manufacturer’s ridiculous rationalizations about...
Naturopathy vs. Science: Fake Diseases
you consult with a naturopath, you could walk out diagnosed with something called Wilson’s Temperature Syndrome. But the naturopath would be wrong, because Wilson’s Temperature Syndrome is a fake disease. One of the hallmarks of alternative medicine is the “fake disease”. Fake diseases don’t actually exist – they are invented without any objective evidence showing that they are real. Fake diseases tend...
