 The comparison with Bohmian mechanics makes clear the sense in which the single-mind theory, the many-minds theory, and the many-thread theory are hidden-variable theories. In each case, it is the determinate value of a “hidden” variable (i.e. a variable not determined by the standard quantum-mechanical state alone) that determines our measurement records, and it is the dynamics of this variable together with the prior probabilities that yields the standard quantum statistics. For his part, Everett explicitly considered such hidden-variable theories but held that his relative-state formulation of pure wave mechanics did not need the addition of such a variable to explain the experience of the modeled observers. This is a good reason to take such theories are failing to capture Everett’s preferred formulation of quantum mechanics.
