The patients know they're eating a pill - the administrators have to tell them something about this pill, even in a double blind study. Did they tell them "this pill contains gluten" (even though the placebo group did not receive gluten) or did they tell them "this pill contains no gluten" or did they tell them "this pill may or may not contain gluten"? Maybe they told them "this pill contains an experimental drug for combatting gluten intolerance". it does matter what they used.
- inyourtenement 12y agoI have some small experience as a study subject. We were given detailed information ahead of time which included what was under study, and whether there would be a placebo group. I guess the assumption is that since both groups receive the same information any placebo effect would be equalized.
- marcosdumay 12y agoIt's a double blind experiment. That means that the person giving them the pill has no idea if it has gluten or not either.
