  We review the Pusey-Barret-Rudolph (PBR) theorem\cite{PBR} and their setup,
and arrive to the conclusion that the reality of a quantum state $\psi$ is
intrinsically attached to the measurement the system described by $\psi$ has
undergone. We show that a state that has not been measured can be regarded as
pure information, while a state that has been measured has to be regarded as a
physical property of a certain system, having a counterpart in reality. This
demonstration implies that the statement of PBR's theorem changes in a
meaningful way.
