I've already noticed that. How you yourself write the whole of the placebo effect.![]()
Thank you for your comments, but I can't take credit on this placebo effect, and other bias related thing. There are plenty of threads on various forums including our own ASR, and lots of members much more knowledgeable than I have posted on the topic.

I would continue to limit my comments on the need to try and remove bias based on my own belief, that's all.
