This is a critical review of the literature on many-worlds interpretations, MWI, with arguments drawn partly from earlier critiques by Bell and Stein. The essential postulates involved in various MWI are extracted, and their consistency with the evident physical world is examined. Arguments are presented against MWI proposed by Everett, Graham and DeWitt. The relevance of frequency operators to MWI is examined; it is argued that frequency operator theorems of Hartle and Farhi-Goldstone-Gutmann… 
Physics versus Semantics: A Puzzling Case of the Missing Quantum Theory
A case for the project of excising of confusion and obfuscation in the contemporary quantum theory initiated and promoted by David Deutsch has been made. It has been argued that at least some
The Many Computations Interpretation (MCI) of Quantum Mechanics
Computationalism provides a framework for understanding how a mathematically describable physical world could give rise to conscious observations without the need for dualism. A criterion is proposed
One world versus many: the inadequacy of Everettian accounts of evolution, probability, and scientific confirmation
There is a compelling intellectual case for exploring whether purely unitary quantum theory defines a sensible and scientifically adequate theory, as Everett originally proposed. Many different and
On the consistent histories approach to quantum mechanics
We review the consistent histories formulations of quantum mechanics developed by Griffiths, Omnès, and Gell-Mann and Hartle, and describe the classification of consistent sets. We illustrate some
The problem of confirmation in the Everett interpretation
On Fundamental Flaws of Everett’s Many Worlds Interpretation of QM, and Plausible Resolution based on Maxwell-Dirac Isomorphism
Everett's MWI is discussed, because it has led to spurious debates on possibility of multiverses, beyond the Universe the authors live in, and two alternatives against MWI proposal are discussed: (a) the so-called scale symmetry theory, (b) the Maxwell-Dirac isomorphism.
The Everett Interpretation
The Everett interpretation of quantum mechanics - better known as the Many-Worlds Theory - has had a rather uneven reception. Mainstream philosophers have scarcely heard of it, save as science
Modal Metaphysics and the Everett Interpretation
Recent work on probability in the Everett interpretation of quantum mechanics yields a decision-theoretic derivation of David Lewis’ Principal Principle, and hence a general metaphysical theory of
Representation Lost: The Case for a Relational Interpretation of Quantum Mechanics
It is argued that unitary evolution has a counterpart in classical probability theory: in both cases (quantum and classical) probabilities relative to a non-participating observer evolve according to an entropy maximizing principle (and can be interpreted as rational opinion updating).


The Measurement Theory of Everett and De Broglie’s Pilot Wave
In 1957 H. Everett published a paper setting out what seemed to be a radically new interpretation of quantum mechanics1. His approach has recently received increasing attention2. He did not refer to
Schrödinger: Are there quantum jumps?
If we have to go on with these damned quantum jumps, then I'm sorry that I ever got involved. E. Schrodinger Introduction I have borrowed the title of a characteristic paper by Schrodinger
Include the Observer in the Wave Function
The classical dynamics of Einstein’s closed universe (idealized for simplicity to be empty except as excited by gravitational waves) is analyzed in no way more economically than by the standard
