In other words, gathering your own anecdote, compounding that with other anecdotes through biased sampling (which kind of person will feel more motivated to share their anecdote on it? And which and anecdotes do you reject because they just didn't try hard enough?) and then projecting that onto every other human being and assuming they must experience the same thing you do.
I never claimed it works for everyone, I am doubting that it is a provable fact that it works for only a minuscule fraction of people- I am not sure exactly what fraction of people this would potentially work for.
You are effectively implying that firsthand experience and expertise are completely worthless, and people can only learn information from large scientific studies, which is nonsense- it would invalidate virtually everything humans know that allows them to effectively navigate the world. I'm a working academic scientist that often designs and executes large studies, and I only ever see these arguments and line of thinking from non-scientists that don't actually understand the limitations of scientific methods, but have turned it into some sort of pseudo-religion.
These are effectively yoga/meditation like techniques that are taught in communities I am part of, and that I have taught to friends and family. I'm not under some delusion that there isn't bias there, I have seen it not work for people, and account for that in my thinking about it. It's been life changing for me, and so I am happy to share info about it in case it might be for others, but I'm not under some delusion that it is the solution to everything.
Correct me if I'm wrong, but I get the impression that your comment isn't really about what I am actually saying, but a general anger towards anything that looks like "pulling yourself up by your own bootstraps"- an anger you can see in other comments in this thread as well. This toxic line of thinking comes from an old fashioned moral argument, that basically derives ones moral standing and worth as a person from the state of being helpless and persecuted, which requires one to actively fight against anything that might be an effective tool to overcome adversity.
I don't agree that using techniques that can help people overcome adversity in any way diminishes the challenges people face, or diminishes things like systematic injustice and addiction that certainly can be due to factors outside of one's control, and hard or impossible to overcome.
Having tools and methods that can, even sometimes, empower people to overcome, survive, and thrive, even if they don't work every time doesn't invalidate those problems, it is just one way to fight them.
