Your arguments against doing science in this case seem fully general to me. They could be used by anyone promoting their brand of alternative medicine no matter how bizarre their claims would be.

What are your suggestions for how to most reliably evaluate anecdotal data? Would it be possible to do some sort of meta-science on this topic? How would you evaluate placebo effects? (Note that I think utilizing placebo too is important.)

I understand many medical treatments aren't RCT based either but the fact that many are kind of makes me trust the mindset of health care professionals more.
