Allow me to use your words directly:
Do you, like Omnes, simply observe that you have predicted probabilities
and so one of them obtains. Or do you go with Evertt and say that all of
them exist with different measures and the apparent randomness is an
illusion due to our consciousness being relative to the different outcomes?
AFAIK, the first possibility could be seen as what a single observer
might perceive and calculate of its world. The latter tries to take
the perceptions of many observers and organize them into a single
structure. I see no necessary conflict between them.
