    It is not the case that Postulating that the properties a subsystem has as a separated system are identical to the properties it has as a subsystem of composite systems leads to inconsistency.

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.Bacciagaluppi (1995) and Clifton (1996a) showed that such property assignment is subject to a Kochen-Specker-type contradiction.
      ?

      Think about whether this reason is strong or weak

    • 2.A Kochen-Specker-type contradiction entails logical inconsistency in the property assignment.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    2 perspectives
    Reason against 1 of 2
    ?
    • 1.Kochen-Specker theorems demonstrate that no hidden-variable theory can assign definite values to all quantum observables simultaneously without contradiction.
      ?

      Think about whether this reason is strong or weak

    • 2.If separated subsystem properties must mirror composite-system properties across all observables, this constitutes precisely the kind of global value assignment Kochen-Specker prohibits.
      ?

      Think about whether this reason is strong or weak

    • 3.Therefore the identity postulate for subsystem properties generates the same contradictions Kochen-Specker proofs establish for hidden-variable completeness.
      ?

      Think about whether this reason is strong or weak

    Reason against 2 of 2
    ?
    • 1.Holism about quantum systems, defended by Teller (1986) and Howard (1989), entails that entangled composites possess non-supervenient relational properties irreducible to their parts.
      ?

      Think about whether this reason is strong or weak

    • 2.If subsystem properties in isolation were identical to their properties within entangled composites, quantum holism would be trivially false, contradicting well-established interpretive results.
      ?

      Think about whether this reason is strong or weak

    • 3.The identity postulate thus presupposes a separability condition that quantum mechanics itself, under any serious interpretation, systematically violates.
      ?

      Think about whether this reason is strong or weak
