The problem with all of these threads remains the same. Every single one of these "hypnosis is a placebo?" has an idea that all things hypnosis are universally the same. But they aren't.
Hypnosis and the entire genre that now falls under it is an extremely diverse culture. For example, the fad of "binaural beats" should never be taken into being the same as the brainwashing hypnosis. For the record, even the harmless for laughs hypnosis of making someone cluck like a chicken briefly counts under this category vaguelly. And even the various brainwashing hypnosis comes in many different branches as I alluded to.
If you want an analogy, think of the many branches of hypnosis like the family tree of lifeforms on earth. All of it is related to one another, but there are thousands of branches. And every one of those branches contains something that is different from the rest in either subtle or vast ways.
But even the definition of what a placebo is can not be universally agreed upon. Some people think it can simply be "all in your head", while others will insist on strict parameters to meet the definition.
Personally I believe the placebo effect to be "If I gave you a glass of dyed water and told you it was medicine that had a specific effect and you then started having that effect."
Now, going with my definition, it means that most of the binaural beats tracks are placebo since they contain 0 words and usually do not even contain a specific mood or emotion inducing music.
However, going by my definition, most of the brainwashing style of hypnosis I would not categorize as a pure placebo. In other words, most binaural beats files if the listener instead listened to 5 minutes of cows mooing with the same "deep thoughts" as they had with the binaural beats file then the results would be exactly the same. Whereas all the cow mooing in the world can not replace the effect some hypnosis tracks can give.
A skilled hypnotist is like a storyteller. They can set a mood. They can take your imagination and run wild with it. They even can make you reconsider your belief system or change how your brain responds to stimuli. The best hypnotists can actually do their work while making the subjects think that it was a failure, even while the changes really have set in,
