Classical versus quantum probability: Comments on the paper "On universality of classical probability with contextually labeled random variables" by E. Dzhafarov and M. Kon

TL;DR

This paper critically examines Dzhafarov and Kon's claim that classical probability coupling techniques can model incompatible quantum observables, discussing the benefits and limitations of this approach.

Contribution

It provides a detailed critique highlighting the advantages and disadvantages of applying classical probability to quantum and psychological models.

Findings

Classical probability coupling can model some quantum phenomena.

There are limitations in modeling incompatible observables with classical probability.

The approach offers both potential benefits and notable drawbacks.

Abstract

Recently Dzhafarov and Kon published the paper advertising the possibility to use the coupling technique of classical probability theory to model incompatible observables in quantum physics and quantum-like models of psychology. Here I present comments on this paper by stressing advantages and disadvantages.
