Quantum measurements with, and yet without an Observer

TL;DR

This paper discusses how Feynman's probability rules and von Neumann's psycho-physical parallelism can resolve inconsistencies in quantum theory by assigning probabilities without wave function collapse and excluding consciousness from measurement processes.

Contribution

It introduces a framework combining Feynman's rules with psycho-physical parallelism to address quantum measurement issues without involving observer consciousness.

Findings

Probabilities can be assigned to entire observer experience sequences.

Wave function collapse is not necessary for consistent probability assignment.

Observer consciousness is excluded from the measurement process.

Abstract

It is argued that Feynman's rules for evaluating probabilities, combined with von Neumann's principle of psycho-physical parallelism, help avoid inconsistencies, often associated with quantum theory. The former allows one to assign probabilities to entire sequences of hypothetical Observers' experiences, without mentioning the problem of wave function collapse.The latter limits the Observer's (e.g., Wigner's friend's) participation in a measurement to the changes produced in material objects,thus leaving his/her consciousness outside the picture.
