Abstract: | Everett’s relative states interpretation of quantum mechanics has met with problems related to probability, the preferred
basis, and multiplicity. The third theme, I argue, is the most important one. It has led to developments of the original approach
into many-worlds, many-minds, and decoherence-based approaches. The latter especially have been advocated in recent years,
in an effort to understand multiplicity without resorting to what is often perceived as extravagant constructions. Drawing
from and adding to arguments of others, I show that proponents of decoherence-based approaches have not yet succeeded in making
their ontology clear. |
