Galvanic Skin Response Pseudoscience

Selling snake oil is all about marketing, which means that a good snake oil product needs to have a great angle or a hook. Popular snake oil hooks include being “natural,” the product of ancient wisdom, or “holistic.” Perhaps my favorite snake oil marketing ploy, however, is claiming the product represents the latest cutting-edge technology.

Six reasons CAM practitioners should not be licensed

States license “complementary and alternative” (CAM) practitioners (chiropractors, naturopaths, acupuncturists/TCM practitioners and homeopaths) via the magic of “legislative alchemy.” Ironically, licensing statutes are enacted based on the states’ constitutional power to protect the health, safety and welfare of the public.

Electrodermal Testing Part II: Legal and Regulatory Aspects

Last week I described electrodermal testing. I’m sure many readers thought, “There oughta be a law against that.” Well, there are laws.

Electrodermal Testing Part I: Fooling Patients with a Computerized Magic Eight Ball

Remember the Magic Eight Ball toy? You could ask it a question and shake it and a random answer would float up into a window: yes, no, maybe, definitely, etc. There is even a website where you can ask an Eight Ball questions online. I have been meaning to write about bogus electrodiagnostic machines for a long time. These devices supposedly diagnose...
