Tylenol May Not Be As Safe and Effective As We Thought

I’ve always thought of Tylenol (AKA acetaminophen in the US and paracetamol in the UK) as one of the safest drugs around, with essentially no side effects when used as directed. But it has been in the limelight lately. Several SBM articles have addressed it here, here, and here. We know there is a risk of liver damage and death with acetaminophen...

The Canadian National Breast Screening Study ignites a new round in the mammography wars

The last couple of weeks, I’ve made allusions to the “Bat Signal” (or, as I called it, the “Cancer Signal,” although that’s a horrible name and I need to think of a better one). Basically, when the Bat Cancer Signal goes up (hey, I like that one better, but do bats get cancer?), it means that a study or story has hit...

The Pollyanna Phenomenon and Non-Inferiority: How Our Experience (and Research) Can Lead to Poor Treatment Choices

Pollyanna, a popular children’s book written in 1913 by Eleanor H. Porter, introduced the world to one of the most optimistic fictional characters ever created. She always saw the good in people and her approach to life frequently involved playing “The Glad Game”, where she attempted to find something to appreciate in every situation no matter how unfortunate. She was glad about...

False “balance” on influenza with an appeal to nature

One of the encouraging shifts I’ve seen in health journalism over the past few years is the growing recognition that antivaccine sentiment is antiscientific at its core, and doesn’t justify false “balance” in the media. There’s no reason to give credibility to the antivaccine argument when their positions are built on a selection of discredited and debunked tropes. This move away from...

HIV Denial and “Just Asking Questions”

The “just asking questions” maneuver is familiar to many skeptics. The idea is to feign neutrality, to insulate oneself from accountability or being held to answer for any specific position, but meanwhile to sow doubt about a scientific claim by raising (dubious) questions. Sometimes the “I’m just asking questions” gambit also tries to disguise itself as sincere journalism. That’s what journalists do,...

How to Think

Robert Todd Carroll, the author of The Skeptic’s Dictionary, has a new book out: The Critical Thinker’s Dictionary: Biases, Fallacies, and Illusion and what you can do about them. Since some of our commenters and most of the CAM advocates we critique are constantly committing logical fallacies, a survey of logical fallacies is a good idea both for us and for them,...

The return of the revenge of high dose vitamin C for cancer

Vitamin C is back in the news as a cancer cure. Is it? No, no it is not.

I Visited a Chickasaw Healer and All I Got Was an Elk Sinew and Buffalo Horn Bracelet

Which headline is real? I Visited a Alchemist. As American alternative chemistry grows in popularity, I decided to experience an even older style of nontraditional transmutation of metals. I Visited an Astrologer. As American alternative astronomy grows in popularity, I decided to experience an even older style of nontraditional stargazing. I Visited a Bloodletter. As American alternative medicine grows in popularity, I...

Twenty days in primary care practice, or “naturopathic residency”

The metastasis of alternative medicine throughout the health care system comes, in no small part, at the hands of the federal and state governments, mostly the latter and most particularly the state legislatures. Under their jurisdiction rests the decision of who can, and cannot, become a licensed health care practitioner, and what they can, and cannot, do. This is the gateway through...

Treating Pain Psychologically

One of the goals of rigorous science is to disentangle various causes so we can establish exactly where the lines of cause and effect are. In medicine this allows us to then optimize the real causes (what aspect of treatments actually work) and eliminate anything unnecessary. Eliminating the unnecessary is more than just about efficiency – every intervention in medicine has a...
