Scope/Content: Before writing a first draft of the long thesis, Hugh Everett wrote three short papers, often refered to as his minipapers, for John Wheeler to review. This minipaper, called "Objective vs. Subjective Probability," presents an early formulation of the quantum measurement problem in terms of a conflict between subjective and objective probabilities. Everett ultimately provided a much clearer formulation of the measurement problem in terms of a conflict between different state attributions in the long thesis. The structure of the experimental setup, however, is similar. There are two versions of this minipaper. The present document is an early handwritten draft. It was found in a file labeled "Early drafts," among Everett's papers.
Scope/Content: This document was found in the basement of Mark Everett in 2007 by Mark Everett and Peter Byrne, in a file labelled "Early drafts."
