Isolated system?

When we ascribe a probability to a physical configuration, are we not arbitrarily assuming

1. That the system excludes the observer,

2. How isolated the system is,

3. How comprehensive the system actually is,

4. The reproducibility of measurement?

Are you talking about quantum mechanics?

E. g., quantum mechanics, thermodynamics, and general relativity - however you would apply physics ultimately to define an experiment.

1. Or, that we exclude QM's interpretation...:wink:

2. Yes.

3. Always.

4. A violation here can exist either due to point
num. 3 or 3 and 2 combined or - if you do not exclude
QM's interpretation, then - due to 1 too.
