It's been a while, so I wanted to reply to at least one comment:
Post: Observer selection effects from scratch
Comment: here
I’m not sure it makes sense to assume that nothing about your observation X favors any of these observers over any other (out of the 101 possible observers distributed among W1 and W2)...
For instance, let’s say... observation B is externally focused (i.e. that apples appear to fall downward). For observation B, it seems that some relevant factors would be how available you think the information is to make that observation (i.e. are there apple trees near others), how likely it is that other people are paying attention, etc. If it seems reasonable that others could be observers too, it seems like that should tilt you more towards believing that you are in W2. I’m not sure, but it seems plausible to me that you should think it’s more than 100 times more likely that you’re in W2 than W1.Thanks for this! I'm not sure that I understand it, though. As far as I can tell, you're saying that some facts about observation B and world W2 could tell us about how likely each observer in W2 is to observe B, right? Like if almost all of the observers in W2 are near apple trees and B is that apples fall downward, it's likely that many observers in W2 will observe B, but if all of W2's observers are in the middle of the ocean, probably few of them will observe B. Is that right?
If so, I totally agree, and I think it's saying the same thing as my post. In my post, I'm not talking about all observers in W1 and W2, but only about those that do actually observe X. In your example, that'd mean there is 1 observer in W1 who sees an apple fall, and 100 in W2 who see the apple fall. That would be in part because of how many observers total there are in each world, but also largely because of where those observers are placed, whether they're paying attention, etc, and it'd be consistent with W1 having millions of observers far from apple trees, asleep, etc -- W2 would still be favored, even with millions of sleeping observers.
Let me know if I've made a mistake, but I think we're on the same page?
