Bell’s theorem demonstrates locality and realism cannot be true of a quantum system. If one performs measurements of observables, eigenvalues that real, then locality does not apply. Wigner’s friend argument illustrates how we can show reality may be abandoned. The following experiment illustrates this. Two observers may witness nature in ways that are not commensurate with each other. The observer then cannot be completely removed from nature.
https://arxiv.org/abs/1902.05080 This is a Bell type of experiment where locality is imposed, but two observers witness two different version of reality. There is then a loss of objectivity to reality, which is the flip side or dual to the standard Bell inequality violation used to demonstrate nonlocality.
