Sure, that's fair.
Peter walked on water out to Jesus because he thought he could; when he looked down and saw the sea, the fell in. As long as he believed Jesus instead of his experience with the sea, he could walk on water.
I don't think the Napoleon story is true, but that's beside the point. He thought he was so tough that an ordinary dose of poison wouldn't kill him, so he took six times the normal dosage. This much gave his system such a shock that the poison was rejected and he lived, thinking to himself, "Damn, I underestimated how incredibly fantastic I am." As long as he (wrongly) believed in his own exceptionalism instead of his experience with poison on other men, he was immune to the poison.
My train of thought was, you have a predictor and a chooser, but that's just getting you to a point where you choose either "trust the proposed worldview" or "trust my experience to date" - do you go for the option that your prior experience tells you shouldn't work (and hope your prior experience was wrong) or do you go with your prior experience (and hope the proposed worldview is wrong)?
I understand that in Newcomb's, that what Omega says is true. But change it up to "is true way more than 99% of the time but less than 100% of the time" and start working your way down that until you get to "is false way more than 99% of the time but less than 100% of the time" and at some point, not that long after you start, you get into situations very close to reality (I think, if I'm understanding it right).
This basically started from trying to think about who, or what, in real life takes on the Predictor role, who takes on the Belief-holder role, who takes on the Chooser role, and who receives the money, and seeing if anything familiar starts falling out if I spread those roles out to more than 2 people or shrink them down to a single person whose instincts implore them to do something against the conclusion to which their logical thought process is leading them.
You seem to be generalizing from fictional evidence, which is frowned upon here, and may explain the downvote (assuming people inferred the longer version from your initial question).
ITT we talk about whatever.
