The concept of indexical uncertainty we’re interested in is… I think… uncertainty about which kind of body or position in the universe your seat of consciousness is in, given that there could be more than one.
I’m not sure I understand yet, but does the following line up with how you’re using the word?
Indexical uncertainty is uncertainty around the exact matter (or temporal location of such matter) that is directly facilitating, and required by, a mind. (this could be your mind or another person’s mind)
Notes:
“exact” might be too strong a word
I added “or temporal location of such matter” to cover the sleeping beauty case (which, btw, I’m apparently a halfer or double halfer according to wikipedia’s classifications, but haven’t thought much about it)
Edit/PS: I think my counter-example with Alice, Alex, and Bob still works with this definition.
