` ::::Not really, other sciences don't really depend on human f/back, which is why EBM has it ``gold standards`` to standarise the non standard f/back.  Of course there are elements of medicine that don't need RCT, broken limbs is one I can think of off the top of my head - no doubt MC will know of others - but ``mechanistic`` type of medical practises probably have a direct corollary with geology, engineering (my b'ground) and the like.  If chemical responses in the manufacture of Vit C gave responses like Humans did (placebo effect and all that) then yes RTC would be a good approach to working out the ``best`` practice of producing Vit C.  But it's a chemical, and we know how to make it, so RTC isn't really needed.  But this is rather by the by.    `
