As far as we know.
How big do you think the sample group should be for you to be positive that placebo effect happens when people know they're getting fake medicine? I'm completely fine with 80 people.
Btw, you mind telling donnie how you found the study - I think he could use the skill

I probably would have looked at the footnote from the Wikipedia quote I linked

We know it for a fact that
placebo doesn't effect infections. The placebo effect is good, but it has its limitations.
I found the study in my reading list today, I guess someone else found about it before me and posted it on Wikipedia.
Grb said that those patients were told that the pill could heal them. You said they were told that it was inert. L2read.
I think you're confused, the patients were told that the pills they're taking are useless sugar pills, but they told them about the placebo effect and how it works. The whole point of the study was to see if the placebo effect will work when the patients know about it.
