Ballentine claims that " generally speaking, the classical limit of a quantum state is not a single classical trajectory, but an ensemble of trajectories". This matches the result that the classical limit of a Wigner function is a version of classical statistical mechanics https://arxiv.org/pdf/1202.3628.pdf

===========

So, is there a consensus on the issue? Does QM go to classical mechanics or classical statistical mechanics (or perhaps neither)?
