Things I'm curious about, but probably won't investigate in detail: Does the placebo effect really do significantly worse if you don't "believe" in it, even if you're (for example) told that it's been experimentally shown to work even if you don't believe in it?
It still works (but less).
Or (I assume) we're not smart enough to find and prove the framing that would maximize the effect's strength for any given human, honestly or otherwise.
