Abstract: We introduce the method of ``intelligent qubits,'' which replace live observers in Wigner's friend and Frauchiger--Renner thought experiments, in order to expose the source of the paradoxes: tacit substitution of Boolean hidden variables for non-commuting quantum propositions. The fallacy traces back to London and Bauer's attempt (1939) to legitimize a self-referential interpretation of observers' ``introspection,'' and thus intertwines the measurement and mind-body problems. We cut the Gordian knot by abandoning reductionism, and describe an alternative which fits, we argue, equally naturally with both physics and anthropology takes on the problems.

Quantum indistinguishability through exchangeable desirable gambles [69.62715388742298]
Two particles are identical if all their intrinsic properties, such as spin and charge, are the same. Quantum mechanics is seen as a normative and algorithmic theory guiding an agent to assess her subjective beliefs represented as (coherent) sets of gambles. We show how sets of exchangeable observables (gambles) may be updated after a measurement and discuss the issue of defining entanglement for indistinguishable particle systems.

The original Wigner's friend paradox within a realist toy model [0.0]
The original Wigner's friend paradox highlights the tension between unitary evolution and collapse in quantum theory. We present a classical toy model in which the contradicting predictions at the heart of the thought experiment are reproduced. The debate surrounding the original Wigner's friend thought experiment and its resolution have striking similarities with arguments concerning the nature of the second law of thermodynamics.

Quantum erasing the memory of Wigner's friend [0.0]
Wigner's friend paradox concerns one of the most puzzling problems of quantum mechanics. At the core of the paradox lies the description of an observer and the object it measures as a closed system obeying the Schr"odinger equation. We argue that the three apparently incompatible properties used to question the consistency of quantum mechanics correspond to two logically distinct contexts.

In [Found. Phys. 48.12: 1669], the notion of 'epistemic horizon' was introduced as an explanation for many of the puzzling features of quantum mechanics. We give a brief presentation of the framework, and then demonstrate how it naturally yields Bell inequality violations.
