Niels Bohr’s Psychological Analogies and Quantum Measurement
Abstract
Abstract In this paper, I suggest that a closer look at Bohr’s analogies to psychology helps us to better understand his interpretation of quantum measurement and how he conceived of the role of the subject in quantum physics. This focus helps us to pinpoint how Bohr’s view on quantum measurement differed from John von Neumann’s and Wolfgang Pauli’s understandings of it. I argue that Bohr’s interpretation of quantum measurement was about ensuring that quantum mechanics is an objective description of quantum phenomena. For Bohr, objective knowledge meant knowledge that can be communicated unambiguously, which requires that there is a sharp division between subject and object. He was adamant that in physics, there is such a sharp division, including in quantum physics. Therefore, he argued, there is no measurement problem in quantum physics.
