 It follows that many results from pilot-wave theories can be imported into Nelson’s stochastic mechanics, including those based on decoherence. In particular, the strategies used in pilot-wave theories to recover the appearance of collapse and the emergence of a classical regime can be applied also to the case of stochastic mechanics, even though so far very little has been done along these lines. Doing so will arguably also resolve some conceptual puzzles specific to Nelson’s theory, such as the problem of two-time correlations raised in Nelson  (2006).[38]
