Relational Quantum Mechanics
(RQM) is the most recent among the interpretations of quantum mechanics that are widely discussed today. It was introduced in 1996, with quantum gravity as a remote motivation (Rovelli 1996); interests has grown since, first very slowly, but steadily, and has peaked during the last years (see Calosi and Riedel 2024, also for a good account of the historical evolution of the interpretation).

This principle plays a crucial role in ensuring the communicability and coherence of events across perspectives, but is incompatible with the orthodox reading of relativity in terms of relationality, and instead requires adoption of a notion of perspectival facts.
