Great article, Bill. Critical thinking is in very short supply. And it will remain so, unfortunately, because the scammers that you exemplify here, know how to play the heuristics game: consumers associate "clinical trials" and lab coats with scientific credentials that need not be questioned or checked out. I'm working and writing in a different health sciences discipline than you, but the scammers and frauds follow the same patterns of deception. On a positive note, it gives us something interesting to write about.
