Wigner's friend paradox: does objective reality not exist?

It is shown that the lack of objective existence of the results of quantum measurements of the state of collapse of the state vector of a remote localized system cannot be proved by an experiment using the reality of violation of Bell's inequality in the Clauser—Horne—Shimony—Holt form. Arguments of a general nature and a specific calculation example confirming this conclusion are also given.

Keywords: Wigner's friend paradox, quantum nondemolition measurements, Bell's inequality, Clauser—Horne—Shimony—Holt inequality, quantum state vector, von Neumann projection postulate, no-communication theorem
