Theories of Everything with Curt Jaimungal · Emily Adlam: Reality Is a Completed Puzzle, Not a Flowing River · 11 Apr 2025 podcast

So it's those kinds of questions pertaining to uh a location within a universe.

Yeah, so we when we talk about um uh self locating uncertainty uh in philosophy or in physics, I think there are two important cl importantly different classes of uh self locating uncertainty that we should distinguish between.

Um so the what I call pure self-locating uncertainty refers to cases where you are uncertain about what location you are out of a possible class of of locations which are all located within the same world.

Uh so for example, uh Adam Elder's case falls into that uh that bracket.

Uh that's a case in which uh Doctor Evil or a person who believes himself to be Doctor Evil receives a credible message telling him that a subjectively identical duplicate has been made of Doctor Evil and placed somewhere.

So in that case, he's now uncertain whether he is in fact the real Doctor Evil or the duplicate, but both of those people exist within one and the same world.

So that is pure self locating uncertainty.

Uh, by contrast, superficially self-locating uncertainty refers to the case where you're uncertain about your location, but the possible locations you could be in belong to different possible worlds.

So for example, uh suppose you wake up and you haven't looked at the clock yet, so you don't know what time it is.

You're uncertain about your location and time.

But of course, in every possible world, there's exactly one time at which you actually wake up.

And so the different possible times

times you could be located in belong to different possible worlds corresponding to those different possible times you could wake up.

So that's I think an importantly different type of self location.

Yes.

Um so the Sleeping Beauty paradox uh in fact involves a mixture of pure and superficially self locating uncertainty.

Um so I think the c the correct way to MRIIS that uh is to uh appeal to your scientific theory to uh determine the superficially self locating credences and then to assign the pure credences any way you want.

So th the the the outcome is that the correct solution is the double half a solution.

Okay, yeah.

So the sleeping beauty paradox refers to a scenario in which uh you'll be an experiment is being performed on you, you're going to be put to sleep, uh, and then you'll be woken up either once or twice in the course of the experiment.
