A Refined Propensity Account for GRW Theory

Abstract Spontaneous collapse theories of quantum mechanics turn the usual Schrödinger equation into a stochastic dynamical law. In particular, in this paper I will focus on GRW theory. Two philosophical issues that can be raised about concern (a) ontology theory, particular nature wave function and its role within (b) interpretation objective probabilities involved dynamics During last years, it has been claimed we take advantage dispositional properties order to develop an for also ground which are postulated by it. However, argue interpretations have discussed literature so far either flawed or—at best—incomplete. If want endorse theory thus need extended account specifies precise those makes clear how they correctly all Thus, after having introduced several different kinds probabilistic dispositions, try fill gap proposing novel complete GRW, based what call spontaneous weighted multi-track propensities. claim such satisfy both our desiderata.
