Do Our Observations Depend upon the Quantum State of the Universe?

Abstract

Generically the probabilities of observational results depend upon both the quantum state and the rules for extracting the probabilities from it. It is often argued that inflation may make our observations independent of the quantum state. In a framework in which one considers the state and the rules as logically separate, it is shown how it is possible that the probabilities are indeed independent of the state, but the rules for achieving this seem somewhat implausible.
