yes...
i think there is some equivocation going on with respect to 'placebo response'...
that is creating problems...
in the drug trials... we want to minimise the aspect of the response that is due to placebo. yes.
but part of how we do that is to... give the placebo group the best freaking placebo we can find...
if that makes sense...
i mean... i don't just want to know that drug x is better than plain packaged plain white pill placebo y... i want to know that drug x is better than fancy packaged colorful capsule brand name equally advertised placebo y.
otherwise... drug x hasn't been shown to be better than placebo. seems to me...
