- I entirely agree. I accept a more relaxed standard of evidence when
- the treatment or effect is harmless. For instance, it can't really
- hurt me to take extra vitamins when I'm feeling sick. So I do. Even if
- it isn't "clinically proven," so what. Even if the only reason I wind
- up feeling better is the placebo effect, so what. I _do_ feel better.
-
- On the other hand, it can be harmful to forego certain treatments that
- are backed up by formal testing protocols. For instance, if I get a
- nasty bacterial infection, I'm going to take antibiotics. I may also
- drink lots of wheat grass juice to restore my body to balance from the
- disease and the side-effects of this conventional treatment, but I
- won't use the juice as a _replacement_ for the antibiotics. That just
- doesn't make sense.
