Here, we present the results of a poll carried out among 33 participants of a conference on the foundations of quantum mechanics. The participants completed a questionnaire containing 16 multiple-choice questions probing opinions on quantum-foundational issues. Participants included physicists, philosophers, and mathematicians. We describe our findings, identify commonly held views, and determine strong, medium, and weak correlations between the answers. Our study provides a unique snapshot of current views in the field of quantum foundations, as well as an analysis of the relationships between these views.
As it’s been queried how many physicists, mathematicians, etc. currently believe what about QM, I thought this paper (no paywall, Yay!) might interest a few of you: A Snapshot of Foundational Attitudes Toward Quantum Mechanics
