Can the Many-Worlds-Interpretation be probed in Psychology?
arXiv Preprint Archive September 15, 2016 Heinrich Päs
A universally valid quantum formalism, assuming only unitary time evolution, leads to a Many-Worlds or Many-Minds scenario via decoherence. However, decoherence requires incomplete information about the environment with which the system becomes entangled. This paper argues that, drawing on neuroscience models of consciousness, the information available to the observer's consciousness defines the environment. This modernizes the von-Neumann-Wigner interpretation, suggesting the quantum-to-classical transition, though hard to test in physics, may become testable in psychology.
