It's not that beliefs affect reality, it's that this reality concept can't be grounded philosophically, especially once you take the notion of a multiverse seriously.

It depends on whether the multiverse includes interactions between universes or not, which most models don't believe, but I've felt similar things to be true at times. They just don't help me tremendously with my schizoaffective symptoms.

Level 1-4 from Tegmark, eternal recurrence from Nietzsche, and modal realism from Lewis all yield the required conclusion. The main thing you need to be true is that for nearly all claims you might want to make about the world, they will be valid in some but not all worlds.

Which under an expansive theory of personal identity, imply that those claims can't be said to be true or false. There's a couple more points you need to make the proof work on a technical level, I think.

I really hope there is not any ability to influence because if there was I would feel obligated to remain in the hell worlds for the sake of trying to make things better or lead people out of them.

Do you consider the world you're in to be a hell world?

Also, as far as I can tell this model doesn't have real implications for what one should do. It makes nearly all the same predictions as one would make otherwise. I've continued thinking about it because it seems underexplored in the literature and I might be missing something.

These sort of thoughts attract cranks, con-artists, and people with mental health issues You try to bring them up with most analytic philosophers or physicists and they direct you to learn the basics of their field and stonewall there, regardless of your credentials or knowledge
