Birds, Frogs, and the Measurement Problem

TL;DR

This paper explores the historical and sociological reasons behind the persistent measurement problem in quantum mechanics, arguing it is more a product of conceptual and social factors than a physical issue.

Contribution

It offers a sociological analysis of the measurement problem's origins and persistence, using Dyson's 'birds and frogs' metaphor to illustrate differing perspectives.

Findings

The measurement problem is largely sociological, not physical.

Dyson's 'birds and frogs' metaphor clarifies different views on quantum measurement.

The problem's persistence is due to conceptual and social factors, not physical inconsistencies.

Abstract

Physicists and philosophers alike have pondered the measurement problem in quantum mechanics since the beginning of the theory nearly a century ago. Marcel Reginatto and I (2013) have made the case as have many others, Niels Bohr among them, that the problem is artificial and needs no resolution. The purpose of my present essay is not to elaborate on this conclusion but rather to shed light on the reasons why the problem arose in the first place and why it persists today, a more sociological than physical reflection. I am indebted to Freeman Dyson for his support of my forays into the foundations of quantum mechanics and, as a tribute to him, make use of his "birds and frogs" metaphor as explained below. I am not suggesting that he would have agreed with my ruminations nor approved of my use of his metaphor. On the other hand, from his writings and my conversations with him, it is clear that Dyson was as dismissive of the measurement problem as Bohr.
