When I hear the phrase "many worlds interpretation," I cringe. This is not because I know something about the science (I know nothing about the science), it's because of confusing things I've heard in science popularizations. This reaction has kept me from reading Eliezer's sequence thus far, but I pledge to give it a fair shot soon.
Above you gave me a substitute phrase to use when I hear "observation." Is there a similar substitute phrase to use for MWI? Should I, for example, think "probability distribution over a Hilbert space" when I hear "many worlds", or is it something else?
Edit: Generally, can anyone suggest a lexicon that translates QM terminology into probability terminology?
You could go with what Everett wanted to call it in the first place, the relative state interpretation.
To answer your "Edit" question, no, the relative state interpretation does not include probabilities as fundamental.
Thanks! Getting back to original sources has always been good for me. Is that "Relative state" formulation of quantum mechanics?
