A simple quantum model linked to a theory of decisions

TL;DR

This paper presents a simplified quantum-inspired model linked to decision-making processes, suggesting quantum mechanics can emerge from a more basic model involving observer choices and conceptual variables.

Contribution

It introduces a new, simpler model connected to decision theory that can derive quantum mechanics under specific conditions.

Findings

Quantum mechanics can follow from a simpler model involving observer decisions.

The model links quantum theory to decision-making processes.

Macroscopic implications of the model are briefly discussed.

Abstract

This article may be seen as a summary and a final discussion of the work that the author has done in recent years on the foundation of quantum theory. It is shown that quantum mechanics as a model follows under certain specific conditions from a quite different, much simpler model. This model is connected to the mind of an observer, or to the joint minds of a group of communicating observers. The model is based upon conceptual variables, and an important aspect is that an observer (a group of observers) must decide on which variable to measure. The model is then linked more generally to a theory of decisions. The results are discussed from several angles. In particular, macroscopic consequences are treated briefly.
