I suppose the fact that it's reduced by blinding the patient is a wash (consistent with both theses), but now you need to add two new causes to explain why single and double blinding work, whereas none of the observed phenomena are inconsistent with other well-known research biases.
- true_religion 12y agoSingle blinding spreads the placebo effect to both groups since both groups think they're getting the treatment. Double blinding reduces the placebo effect, since the researcher can't imply to the patient which treatment is actually real and which is placebo since they don't know.
