Update on ASEA, Protandim, and dōTERRA

Multilevel marketing distributors of dietary supplements and essential oils point to studies that they think constitute evidence that their products work. They don’t understand why those studies are inadequate. I have written critiques of several dietary supplements sold through multilevel marketing (MLM) schemes, and they keep coming back to haunt me. I get testimonials from

Evidence: “It Worked for My Aunt Tillie” Is Not Enough

Evidence means different things to different people. Even quacks and their victims claim to have evidence that their treatments work. Sometimes that evidence consists only of testimonials from satisfied customers or from personal experience. “I tried X and I got better.” “I know Y works because it cured my Aunt Tillie’s arthritis.” I had a

Defending Science-Based Medicine: 44 Doctor-Bashing Arguments …and Their Rebuttals

Supporters of alternative medicine and purveyors of quack remedies love to criticize conventional medicine and science. They keep repeating the same tired arguments that are easily rebutted.

On Miracles 

Is there such a thing as a miracle? Miracles are defined as unusual events that are not explicable by scientific or natural laws and that are assumed to be the result of supernatural intervention. The very concept is so fuzzy that it borders on the unintelligible. Religious believers refer to many things as miracles: the

Answering Our Critics, Part 1 of 2

Some people don’t like what we have to say on Science-Based Medicine. Some attack specific points while others attack our whole approach. Every mention of complementary and alternative medicine (CAM) elicits protests in the Comments section from “true believer” users and practitioners of CAM. Every mention of a treatment that has been disproven or has not

Bigfoot Skepticism is Alive and Well

The term “Bigfoot Skeptics” was recently coined by special interest groups among feminists, atheists, and libertarians to disparage those who pursue traditional skeptical topics instead of addressing the issues of social injustice, religion, and politics that they would rather focus on. “Bigfoot Skeptics” are seen as wasting their time rehashing trivial subjects. I’ve heard from

Evidence-Based Medicine, Tooth Fairy Science, and Cinderella Medicine

The term evidence-based medicine (EBM) first appeared in the medical literature in 1992. There were two previous EBMs: Expert-Based Medicine and Experience-Based Medicine. In the 4th century BCE, Aristotle said men have more teeth than women. He was the expert, and for many centuries his error was perpetuated because no one dared question his authority
