Christopher Fuchs and Rudiger Schack have developed a way of understanding science, which, among other things, resolves many of the conceptual puzzles of quantum mechanics that have vexed people for the past nine decades. They call it QBism. I speculate on how John Bell might have reacted to QBism, and I explain the many ways in which QBism differs importantly from the orthodox ways of thinking about quantum mechanics associated with the term “Copenhagen interpretation.”

This paper attempts to lay out Niels Bohr's pragmatic approach to science in general and to quantum physics in particular, and concludes that there are important differences.
On Quantum Bayesianism
The lately developed part of Quantum Bayesianism named QBism has been proclaimed by its authors a powerful interpretation of Quantum Physics. This article presents analysis of some aspects of QBism.
The (Quantum) Measurement Problem in Classical Mechanics
In this work we analyze the deep link between the 20th Century positivist re-foundation of physics and the famous measurement problem of quantum mechanics. We attempt to show why this is not an
On Modern Approaches to the Einsteinian View of Quantum States
Quantum mechanics notoriously faces the measurement problem, the problem that if read thoroughly, it implies the nonexistence of definite outcomes in measurement procedures. A plausible reaction to
On Probabilities in the Many Worlds Interpretation of Quantum Mechanics † U niversity of C ologne
Quantum Mechanics notoriously faces a measurement problem, the problem that the unitary time evolution, encoded in its dynamical equations, together with the kinematical structure of the theory
Is QBism a Possible Solution to the Conceptual Problems of Quantum Mechanics
This work will examine if QBism's claims are robust and will show that a certain number of issues needs to be clarified in order to get a coherent picture.
The Reality of the Wavefunction: Old Arguments and New
The recent philosophy of Quantum Bayesianism, or QBism, represents an attempt to solve the traditional puzzles in the foundations of quantum theory by denying the objective reality of the quantum
Bohr, QBism, and Beyond
QBism may be the most significant contribution to the search for meaning in quantum mechanics since Bohr, even as Bohr's philosophy remains the most significant revision of Kant's theory of science.
Notwithstanding Bohr, the Reasons for QBism
Without Niels Bohr, QBism would be nothing. But QBism is not Bohr. This paper attempts to show that, despite a popular misconception, QBism is no minor tweak to Bohr's interpretation of quantum
QBism, FAPP and the Quantum Omelette. (Or, Unscrambling Ontological Problems from Epistemological Solutions in QM)
In this paper we discuss the so called "quantum omelette" created by Bohr and Heisenberg through the mix of (ontic) objective accounts and (epistemic) subjective ones within the analysis of Quantum
