 Instead, QBists Fuchs and Schack (2012) have viewed decoherence as a condition on an agent’s present assignment of a quantum state to a system following one contemplated measurement, when making decisions regarding the possible outcomes of a second measurement. As such, it functions as a normative synchronic coherence condition that may be seen as a consequence of van Fraassen’s (1984) Reflection Principle. Instead of taking decoherence to select possible outcomes of a physical measurement process, QBists take these to be just whatever experiences may follow the agent’s action on the world.
