Wigners Friend as Illicit Scope Transport

This paper reanalyzes the Wigner’s Friend scenario as a case of illicit scope transport rather than as evidence of paradox, observer-dependence, or foundational incompleteness in quantum mechanics. It shows that the apparent contradiction arises when descriptive commitments licensed in one representational scope are improperly exported into another without admissible justification. Within a closed admissibility framework, observer-relative descriptions are not interchangeable by default. Each description is licensed only within a specific scope defined by standing, reference, and expressive constraints. The Wigner’s Friend paradox emerges when a state description valid within the friend’s scope is treated as if it must remain valid under an external observer’s incompatible scope, collapsing representational separation into apparent inconsistency. The analysis is eliminative. It does not introduce new interpretations of quantum mechanics, propose resolution mechanisms, or modify measurement postulates. Instead, it establishes a boundary condition: cross-scope state identification is inadmissible unless standing-preserving transport conditions are satisfied. Where these conditions fail, the resulting contradiction is not physical but representational. By classifying Wigner’s Friend as a scope error rather than a quantum mystery, the paper dissolves a class of arguments for observer-relative reality, branching worlds, or relational ontology. It closes the problem by showing that the paradox is generated by an illicit move between descriptive regimes, not by any failure of quantum theory itself.
