    Supports→A quantum observer can simultaneously be in an entangled superposition of having recorded mutually incompatible results (from an external observer's perspective) and yet have obtained a fully determinate measurement result (from their own perspective), with those determinate results satisfying standard quantum statistics.

    There are no collapses of the quantum-mechanical state.

    In his version of the Wigner’s Friend story, Everett insisted on three things simultaneously: (1) there are no collapses of the quantum-mechanical state, hence \(B\) is correct in attributing to \(A{+}S\) a state where \(A\) is in an entangled superposition of having recorded mutually incompatible results, (2) there is a sense in which \(A\) nevertheless got a fully determinate measurement result, and (3) such determinate results satisfy the standard quantum statistics.
