  Recall (section 5.1.2) that there are several models of state reduction in the literature. One of these models is the so-called non-linear Continuous Stochastic Localization (CSL) models (see Pearle 1989, Ghirardi, Pearle and Rimini 1990, Butterfield et al. 1993, and Ghirardi et al. 1993). Butterfield et al. (1993) argue that in these models there is a probabilistic dependence of the outcome of the R-measurement on the process that leads to the (earlier) outcome of the L-measurement. In these models, the process leading to the L-outcome (either z-spin ‘up’ or z-spin ‘down’) depends on the interaction between the L-particle and the L-apparatus (which results in an entangled state), and the specific realization of the stochastic process that strives to collapse this macroscopic superposition into a product state in which the L-apparatus displays a definite outcome. And the probability of the R-outcome depends on this process. For example, if this process is one that gives rise to a z-spin ‘up’ (or renders that outcome more likely), the probability of R-outcome z-spin ‘up’ is 0 (more likely to be 0); and if this process is one that gives rise to a z-spin ‘down’ (or renders that outcome more likely), the probability of R-outcome z-spin ‘down’ is 0 (more likely to be 0). The question is whether there are controllable factors that influence the probability of realizations of stochastic processes that lead to a specific L-outcome, so that it would be possible to increase or decrease the probability of the R-outcome. If such factors existed, controllable probabilistic dependence would be possible at least in theory. And if this kind of controllable probabilistic dependence existed, λ-distribution would also obtain; for if such dependence existed, the actual distribution of pairs' states (in which the pair always have the same state, the quantum-mechanical state) would cease to be the quantum-equilbrium distribution.
