Which is not in "that context", of a wavefunction.

Really? Are you saying that the Sh. eq. gives a
measure distribution for "outcomes" of "observables"
even when there are no obserrver-moments? What is
that supposed to mean?
If by "observables" you mean Hermitian operators,
how does the Sh. eq. do the above?
My view, as I have stated repeatedly, is that it
should be possible to derive a measure distribution
for computations implemented by a physical system and
that given a wavefunction & the Sh. eq., it should be
possible to show that the ratios of the measures of
appropriate computations that could be conscious (if
present, e.g if there is a brain in the system) to the
total measure of such are the usual effective

What's a "quantum history"? Any relation to the
"consistent histories interpretation"?
