Right! Nothing "has to obey" the Uncertainty Principle. Remember that
the outcome of any experiment can only be predicted with a probability.
So it's "possible" that we could make consecutive alternate measurements
of an electron's position and momentum, and find that they seem to be
well defined. But that's not usually what is seen. The odds of that
are very small. I think (if I may be so bold) that James was trying
to point out that we are in a universe that has a lot of non-sensical
things going on - just very rarely.
If we assume that this idea of a measure over universes is possible to
define, then there *will* be some mathematically derivable laws of
physics (read, "laws of probability") based on the relative SSA -
that is, what the next conscious observer moment will be, given the
current conscious observer moment. We'd like to show that these laws
are the ones we observe. Regardless, it seems plausible to assume that
the laws connecting observer moments when the observer is, say, 10
years old, are qualitatively the same as those when she's, say, 30
years old. Hence consistency. Hence, no flying rabbits.
