Not exactly a household name, Marcus Laux is in any case a very typical example of how woo is peddled. He is “a licensed naturopathic physician who earned his doctorate at the National College of Naturopathic Medicine in Portland, Oregon. He has been clinically trained in acupuncture, homeopathy, physical medicine, among other healing modalities.” His biography is here.
It’s all there. He chose the woo route because “[science-based medicine] doctors seemed more interested in money than their patients” and – predictably – because naturopathic medicine “looks beyond the symptoms to the source, treating you as a whole person rather than a bunch of separate, unrelated symptoms”. But of course, Laux initially thought naturopathic medicine was quackery, However, he “knew in [his] heart [i.e. rather than by evidence] that the natural path was the right path” (in short, he found fallacious appeals to nature extremely intuitively compelling). He is also coauthor of “Natural Woman, Natural Menopause” (with Christine Conrad) and “Top Ten Natural Therapies” (with Melissa Block).
His web page is here. Now, Laux is the founder of Qivana, a network marketing company peddling all sorts of wellness products (woo-based, of course – no, you don’t get a link) in what they call the “Qivana Qore” series (it even has “Qi” in the name to give them away).
Diagnosis: This is how great woo is done; while Laux may be a fraud, it's more likely he is completely oblivious to the fishiness of his approach to medicine or business. Not very influential or likely to become very influential, but he is still not unlikely to cause some harm.
