Abstract
In a recent paper (Found Phys 54:14, 2024), Carcassi, Oldofredi and Aidala concluded that the psi-ontic models defined by Harrigan and Spekkens cannot be consistent with quantum mechanics, since all pure states of these models must be orthogonal to each other according to their information theoretic analysis, in clear violation of quantum mechanics. In this paper, I argue that this no-go theorem for psi-ontic models is false.
