TL;DR
This paper examines the preferred basis problem in relational quantum mechanics, demonstrating its formal consistency and comparing its practical implications with Bohmian mechanics.
Contribution
It provides a formal analysis of RQM's consistency and offers a FAPP perspective comparing RQM with Bohmian mechanics.
Findings
RQM's formalism is immune to recent consistency critics
Analysis of interaction in RQM supports its practical applicability
Comparison shows RQM and Bohmian mechanics are similar for practical purposes
Abstract
The aim of this article is to discuss the preferred basis problem in relational quantum mechanics (RQM). The issue is at the heart of quantum mechanics and we first show that the mathematical formalism of RQM is immune to recent critics concerning consistency. Moreover, we also analyse the notion of interaction in RQM and provide a For All Practical Purposes (FAPP) reading of RQM comparing it with Bohmian mechanics.
