I say 'mostly' because pushing the Heisenberg cut all the way to include conscious observers, as in Everett's interpretation of QM, is still a little controversial because we lack a good theory of consciousness.
Isn't that rather like saying "assuming that gravitation applies the same way to conscious observers as to everything else is still a little controversial because we lack a good theory of consciousness"? I mean, there isn't actually any good reason to think that conscious observers are treated specially by the universe; it's just a sad historical accident that early speculation about how QM works happened to treat conscious observers (or at least their "measurements") specially. (No doubt the above is "a little controversial" -- but that's not really the same as saying it's likely to be wrong.) -- g
