Abstract

Healey recently argued that a version of the extended Wigner's friend Gedankenexperiment due to Masanes establishes a contradiction between the universal applicability of unitary quantum theory and the assumption of definite outcomes [Found. Phys. 48, 1568 (2018)]. In this Comment, I show that Healey's analysis is problematic and his conclusion is not true.
