Matthew S. Leifer* I was excited to read this new book by Hans Christian von Baeyer because QBism is the reason I do research in quantum foundations, or, more accurately, Chris Fuchs is. Around the early 2000s, Chris appeared at almost every conference I went to, preaching the gospel of what was then called Quantum Bayesianism, now QBism. As a student who wanted to delve into the meaning of quantum theory, but who had chosen to study quantum information as a more practical option, those were heady times. Here was someone claiming to be able to solve all the mysteries of quantum theory with a simple change in how we understand quantum probabilities as subjective Bayesian probabilities rather than relative frequencies or objective chances. As a natural skeptic, I thought that there must be something wrong with this and resolved to determine what. In the two-month break between my PhD and my first postdoc, I read everything that had then been written TI - Book Reviews JF - Physics in Perspective DO - 10.1007/s00016-017-0196-5 DA - 2017-03-22 UR - https://www.deepdyve.com/lp/springer-journals/book-reviews-V8xml4PRu5 SP - 76 EP - 87 VL - 19 IS - 1 DP - DeepDyve ER -
