 Contemporary QBists (Mermin 2014: 422; Fuchs 2011) have sought precedents among such authorities as Erwin Schrödinger, Niels Bohr, Wolfgang Pauli, J.A. Wheeler, and William James. But what came to be known as quantum-Bayesianism and later QBism began as a collaboration between Caves, Fuchs, and Schack at the turn of the 21st century (Caves, Fuchs, and Schack 2002a,b), although Caves no longer considers himself a QBist. N. David Mermin (2014, 2019) became a convert more recently and has proposed extending the QBist vision of science to resolve at least one long-standing conceptual issue raised by classical physics. Stacey (2019,  Other Internet Resources)  tracks changes from the Quantum-Bayesianism of 2002 to the QBism of 2019.
