On QBism and Assumption (Q)
Blake C. Stacey
TL;DR
This paper clarifies misconceptions in recent quantum physics literature regarding the Wigner's Friend thought-experiment, focusing on accurately representing physicists' beliefs.
Contribution
It corrects two specific misunderstandings—one historical and one conceptual—in the context of quantum extensions of Wigner's Friend.
Findings
Clarifies the historical context of the misconceptions
Provides a conceptual correction to the interpretation of beliefs in quantum physics
Enhances understanding of the philosophical implications of Wigner's Friend
Abstract
I correct two misapprehensions, one historical and one conceptual, in the recent literature on extensions of the Wigner's Friend thought-experiment. Perhaps fittingly, both concern the accurate description of some quantum physicists' beliefs by others.
