So you meant something like "counterfactually, it's more likely that Steve Jobs changed his mind about treatment than it is that he didn't get pancreatic cancer." Because the evidence that could support this claim is mostly macroscopic statistical evidence, I feel like phrasing this in terms of quantum mechanics ("the amplitude of outcomes where steve jobs changed his mind etc. etc.) actually makes it more difficult to support.

Indeed, I'm beginning to see that alternatives that are counterfactually likely have perhaps no relationship with nearby Everett branches. For example, 'if I didn't become a chemist I probably would have been a biologist' may be true but nevertheless might have nothing to say about how near the two possibilities are in terms of quantum states.
