The first requirement is not telling the patient the theory about which specific bone supposedly causes their illness. Since there is no obvious way for them to know this, that part is pretty secure. Even if they knew the difference between the C-1 and C-2, they wouldn’t know which one is supposedly going to cure their hypertension. The part that sounds tricky, administering the treatment blindly, really isn’t. The person who administers the treatment does not have to be the same as the person who later examines the patients to see which ones have improved. With drug treatments, it is easy to hand someone a pill without knowing what is in it, but the important detail is that the person assessing the patient’s progress not know. So it’s OK if the chiropractor knows if he is doing the “real” treatment or the “sham” treatment, as long as he isn’t the one who decides whether or not it “worked”. We don’t know for sure if they did do the experiment correctly, but they could have. BUT… I ha
