What kind of a friend is Wigner's?

TL;DR

This paper critically examines an experiment related to Wigner's friend paradox, arguing that its relevance to resolving the paradox is limited despite its experimental rigor.

Contribution

It provides a philosophical critique of the experiment's implications for the Wigner's friend paradox rather than presenting new empirical or theoretical results.

Findings

The experiment's design does not fully address the paradox

The relevance of the experimental results to the paradox is limited

The paper offers a philosophical analysis rather than empirical data

Abstract

Proietti et al. (arXiv:1902.05080) reported on an experiment designed to settle, or at least to throw light upon, the paradox of Wigner's friend. Without questioning the rigor or ingenuity of the experimental protocol, I argue that its relevance to the paradox itself is rather limited.
