So the problem is something like it's pretty obvious when someone has taken a psychedelic and no one has figured out a good placebo that can honestly blind the observer. The counter-argument I've heard is well, should everything in medicine be subject to the double-blind gold standard? Or put another way, is there a class of experiments where the double-blind standard is not applicable to? Is it right to discount a class of experiments just because the proponents of the double-blind standard can't figure out a way to make the double-blind applicable? I'm a hacker not a doctor, but my instinct is "well, if the only tool you'll accept is a hammer, it's kinda up to you to make this thing look like a nail."
