IIRC you were the one carrying on about childbirth being "punishment for Eve's transgression"
I'm sorry if you misunderstood. I was quoting the Genesis, which is one of the books of the Bible. I am not personally of the opinion that all women should suffer in childbirth because of Eve's transgression.
Achnowledging a possible state where homeopathy might not work is different the inflexible POV that it has already happened. Your, "What would it take for you to be convinced that..." attitude suggests inflexibility. There can be no consensus if you prejudge the result.
I think we probably have somewhat different ways to think about things since I frequently fail to understand your paragraphs. You originally said:
"Even if homeopathic medicines turn out to be inert placebos, placebos still have a level of effectiveness that exceeds doing nothing."
And I asked you what events would bring about this "turn-out-to-be" state. What debunking would be sufficient? What test failure would do? Conversely, I can easily outline circumstances in which I would accept homeopathy as valid. I consider it beyond the realm of the probable - but it could theoretically happen. Allow me to quote from Richard Feynman, he puts it better than I ever could.
- - - Example. I'm in Las Vegas, suppose. And I meet a mind reader, or, let's say, a man who claims not to be a mind reader, but more technically speaking to have the ability of telekinesis, which means that he can influece the way things behave by pure thought. This fellow comes to me, and he says, "I will demonstrate this to you. We will stand at the roulette wheel and I will tell you ahead of time whether it is going to be black or red on every shot."
I believe, say, before I begin, it doesn't make any difference what number you choose for this. I happen to be prejudiced against mind readers from experience in nature, in physics. I don't see, if I believe that man is made out of atoms and if I know all of the - most of the - ways atoms interact with each other, any direct way in which the machinations in the mind can affect the ball. So from other experience and general knowledge, I have a strong prejudice against mind readers. Million to one.
Now we begin. The mind reader says it's going to be black. It's black. The mind reader says it's going to be red. It's red. Do I believe in mind readers? No. It could happen. The mind reader says it's going to be black. It's black. The mind reader says it's going to be red. It's red. Sweat. I'm about to learn something. This continues, let us suppose, for ten times. Now it's possible by chance that that happened ten times, but the odds are a thousand to one against it. Therefore, I now have to conclude that the odds that a mind reader is really doing it are a thousand to one that he's not a mind reader still, but it was a million to one before. But if I get ten more, you see, he'll convince me. Not quite. One must always allow for alternative theories. There is another theory that I should have mentioned before. As we went up to the roulette table, I must have thought in my mind of the possibility that there is collusion between the so-called mind reader and the people at the table. That's possible.
...
Now suppose that we go to another club, and it works, and another one and it works. I buy dice and it works. I take him home and I build a roulette wheel; it works. What do I conclude? I conclude he is a mind reader. - - -

Your link redirects me to an nih site on nucleic acids and the word "placebo" does not appear there at all.
Sorry, I had two PubMed links open - that one was something I was using for my M.S. thesis. My bad :) A Google search will reveal the page I intended to send you to.
If the data on the placebo effect is of such poor quality it does not strike me as scientific to novertheless use it as a reference standard.
I think this article probably argues for more research into the placebo effect. If you search PubMed for the words "placebo effect" you will, however, find a reasonable amount of recent articles.
How does the "effect in the placebo arm" differ from the "placebo effect"?
Not having actually read the article I cannot say for sure. My guess is that they want to distinguish the *change* that occurs in the placebo arm of an experiment from the *effect* of the placebo they are given. That is to say a part of the placebo group may get better without it having anything to do with the placebo - they might have gotten better even without it.
