Interpretation of Quantum Mechanics

What is it about?

Bohr's interpretation of quantum mechanics emphasizes the use of classical concepts as a necessary requirement for understanding the experimental outcomes in quantum mechanics. This presupposition behind the so-called Copenhagen interpretation can be traced back to the evolution of human experience. Another interpretation, QBism ,seems also to rely on cognitive Darwinism. However, a comparison between Bohr's view and QBism reveals similarities but also some important differences.

Why is it important?

Bohr's philosophy of quantum mechanics has wrongly been accused for being subjective and mind-dependent. A more careful look shows that Bohr's view is far from subjective and that it cannot be compared in this respect to the Bayesian approach to probability one finds in QBism. Rather Bohr's interpretation was based on a pragmatic view on quantum phenomena, where the physical context of the experiments and frequentist interpretation of probabilities are the corner stones of a naturalized understanding of quantum phenomena.
