Peter,if we 'free-up' our minds to think wider than our conventional sciences based 'unconventionality' (as applied on this list frequently) and recognize the unlimited Everything in the complexity of the wholeness we end up in (my?) agnosticism:We know only part of the total, visualize WITHIN our mind-restricted imaging and formulate 'models' of the already known world (already: because it widened by newer input historically as we 'learn'). The totality's inter influenceing results in changing relations - partly followable - acknowledged by the part of our 'then' knowledge.In such view "Random" is "I don't know", Chaos is: "I don't know" and stochastic is sort of a random.
What conventional science does is a compromise into the "almost": our technology is "almost perfect", some planes fall off from the sky, some sicknesses/wars break out, some genetic mishaps occur, some theories fail, etc. etc. Compromising means to invent cute factors that enhance a match (at least mathematically) in cases of trouble. Presumptions make assumptions and vice versa, in endless series and at the end it is believed as a fact.Deterministic? there is SOME order that keeps the world churning, applying ALL relational changes in the wholeness including ALL ingredients of the Everything. We don't know whatare such 'ingredients' only the imagined 'model-substitutions' we use in our limited knowledge.

This makes a false constrast between models and out current knowledge.
Our current knowledge, so called, is just embodied in our models which
we rely on, pending further discoveries. To recognize that the
intrinsic randomness of QM is just an element of our current model no
more justifies asserting that real reality must be deterministic than
noting that our current model of the Earth as a bumpy ellipsoid is
subject of refinement, justifies asserting the Earth is flat. It's is
fine, and scientific, to criticize our current knowledge - but it needs
to be supported by more than just the fact that our knowledge is
provisional, because it will *always* be provisional.

I think this bespeaks a common misconception; perhaps related to the
indeterminism=not-determinism Peter points to above. Random doesn't
mean "anything can happen" or "nothing can be predicted". It can be
used to model something that is deterministic, but not worth the effort
to determine, or something that is not determined. But it may be very
constrained. Something may be random, but within a very small range.
And they may be very well described by know distributions - as is the
case for coin tosses and nuclear decays.

OK. (BM = Brent Meeker, here, not me). But I agree with Brent, and a perfect example of such intrinsic randomness is a direct consequence of determinism in the computer science. That is what is illustrated by the iteration of self-multiplication. Most observers, being repeatedly duplicated into W and M, will have not only random history (like WWMMMWMMMWWWWWMWMMWWM ...) but a majority will have incompressible experience, in the sense of Chaitin. Self-duplication gives an example of abrupt indeterminacy (as opposed to other long term determinist chaotic behavior).
In particular, the empiric infered QM indeterminacy confirms one of the most startling feature of digital mechanism: that if we look below our computationalist subtitution level , our computations (our sub-level computations) are random.
This is easily explained by the digital mechanist assumption, through
self-duplication. No need of QM, except for a confirmation of comp.
Note that he non cloning theorem is itself a consequence of digital
mechanism. In fact all the weirdness of quantum mechanics are obvious
in digital mechanism (DM, which does not postulate QM). Indeed DM
entails first person indeterminacy, first person plural indeterminacy
(many worlds), first person non locality, and it is an "easy" exercise
to show that it entials non cloning of matter, and non emulability of
matter (and thus the falsity of digital physics a priori).
It is still an open problem if unitarity follows from comp, as it
should if both DM and QM are correct. But the room for unitarity is
already there, because the logic of arithmetical observability by
machine/numbers is indeed a quantum logic. Comp can be said to already
implies that the bottom physicalness is symmetrical and non clonable.
The arithmetical qubit cannot be cloned nor erased (nor emulated by a
digital machine, and this is perhaps not confirmed by QM!).

This is a consequence of the no-cloning theorem, which in turn is a consequence of unitary evolution of the wf. It is curious that the deterministic process at the wf level implies randomness at the level of conscious experience.

I am sure you write very smart things. I am not so familiar with the letters used as abbreviations (wf, DM and more) so I just listen to the music.One thing though I am sure:all you include is included within our yesterdays knowledge-base what is for sure more than the knowledge base way back before yesterday - and LESS than it will be tomorrow (or say 1000 years from now).
I formulate my 'opinions' (oh, not arguments, for heaven's sake) in my agnosticism about such adages in the future invalidating some "nice and acceptable" TRUTH we pamper in our present thinking.If there is 'random' in your worldview, how is it restricted in a way not to interfere with those "LAWS" conventional sciences formulated before such random changes occurred?
Also: it may be my imperfection in my vocabulary, but erasing 'random' - making every change in relations based on some 'originating' factor - shows a DETERMINISTIC and not some indeterministic view.
We may not clearly identify all those originating factors (e.g. in the so far not detected parts of the totality), but so works my agnosticism.
The PHYSICAL WORLD is a nice figment and we can live with it for now.

Exactly what I am asking. Is this a possibility?
It is a logical possibility. But it is inconsistent with the computationalist hypothesis in the cognitive science, or with the idea that QM is a universal theory.
The collapse of the wave has been defended during almost one century and nobody can explain it. The observer can no more be described by quantum mechanics, nor by digital mechanism.
But it is not a logical contradiction. It is just not plausible, a bit like the idea that God made the creation in six days some millennia ago. We can't contradict such a statement, but it necessitates a very complex theory with many "corrective principles" which will be seen as ad hoc.
(JM): how were the "SIX DAYS" measured before OUR time-frame was 'created???
In science we never know-for-sure the truth. There are no certainties.
(JM): conventional science, that is. We cannot speak for the future.
With computationalism we have a quasi complete explanation of consciousness, capable of justifying completely its own incompleteness, and a complete explanation (although not yet completed, to be sure) of the origin of the appearance of physical reality (both the quanta and the qualia).To allow consciousness to make the other branches, or the other computations disappearing, seems to me a bit like making a problem much more complex for unclear reason.But comp might be false, that is a possibility. Indeed, if comp is true, it has to be a possibility. Comp, like consistency in arithmetic entails the possibility of its refutation, and should never been taken as an axiom, just a meta-axiom, or an act of faith. If not, we become inconsistent.
My point here is just to explain that IF comp (DM) is true, THEN physics is a branch of machine's psychology/theology/biology. I don't pretend this is obvious.I do find comp plausible from the currently available data. Both comp, the hypothesis, but also through its multiverse/multidream consequences.Bruno

In that case we must search for another theory in mind studies, and another theory in physics studies. But today, they work well, especially together, and the more we study them, the more astonishing they look. I like them, because I like to surprises. I like theories which shake my prejudices.

A theory can always be false. The problem of the collapse of the wave function is that it has to violate relativity, or physical realism or logic. Without collapse, an observer is at least as realistic than the objects of his study. The observer does not need a special status, he belongs to the world he is observing.

Note that is exactly contrary to some interpretations of QM, e.g. Bohr's
http://arxiv.org/PS_cache/arxiv/pdf/1009/1009.4072v1.pdf
and more recently Asher Peres
http://arxiv.org/PS_cache/quant-ph/pdf/9711/9711003v1.pdf
The "collapse" of the wave function is easily explained as an epistemic event in one's description of the system.
"Relational connection" is very broad, so I'd say it's certainly
possible for a mental object, a thought, to have a relational connection
to another mental object (one thought follows another) or to a physical
object (I thought of a chair). When we speak of observing and observers
there is usually an implication that others could also observe the
'same' thing (allowing for points of view differences). This is why
Bohr emphasized the logical priority of the classical in empirical science.
