    In environmental decoherence models with coherent preferred states, the resulting trajectories of individual components will be close to Newtonian ones on relevant scales.

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.Preferred coherent states follow the Schrödinger equation more or less undisturbed because they are least entangled with the environment.
      ?

      Think about whether this reason is strong or weak

    • 2.Narrow wave packets that follow the Schrödinger equation approximately follow Newtonian trajectories when external potentials are sufficiently uniform across the packet width.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    2 perspectives
    Reason against 1 of 2
    ?
    • 1.Decoherence selects preferred bases relative to a choice of system-environment partition, which is not determined by the formalism itself.
      ?

      Think about whether this reason is strong or weak

    • 2.Without a principled, non-anthropocentric criterion for the partition, 'Newtonian trajectories emerge' inherits an ineliminable element of observer-relative stipulation.
      ?

      Think about whether this reason is strong or weak

    • 3.A result that depends on a freely chosen partition cannot ground the objective classical world decoherence theorists claim to derive.
      ?

      Think about whether this reason is strong or weak

    Reason against 2 of 2
    ?
    • 1.Decoherence suppresses interference terms in the reduced density matrix but does not eliminate the other branches of the universal wavefunction.
      ?

      Think about whether this reason is strong or weak

    • 2.Newtonian trajectories describe single, determinate histories, whereas the post-decoherence state remains a superposition of approximately classical components.
      ?

      Think about whether this reason is strong or weak

    • 3.Approximating Newtonian behavior within each branch presupposes the very individuation of branches that decoherence alone, without additional interpretive commitments, cannot provide.
      ?

      Think about whether this reason is strong or weak

    In a number of models of environmental decoherence, however, it is obvious what the dynamical behaviour should be even at the level of individual components. Specifically, in models where the preferred states are coherent states, comparison of the master equation for the reduced state of the system with the evolution of a classical Liouville distribution suggests that the trajectories of individual components in fact approximate surprisingly well the corresponding Newtonian trajectories.
