Are Placebos Really Sugar Pills?
It would be interesting to do placebo vs. placebo trials (telling patient A he's getting a specific drug and giving him a placebo instead, and telling patient B he's getting another drug which treats the same condition, and also giving him a placebo).<p>i.e. would you subjectively report more pain relief when given ibuprofen (placebo) vs. vicodin (placebo).<p>But, pesky IRBs :(
