    It is not the case that Preferred coherent states tend to get least entangled with the environment and therefore follow the Schrödinger equation more or less undisturbed.

    ?Set your confidence on the premises below to see your aggregate.

    Reasons For

    2 perspectives
    Reason for 1 of 2
    ?
    • 1.The selection of 'preferred' coherent states presupposes a classical environment, making the argument circular when explaining classicality's emergence.
      ?

      Think about whether this reason is strong or weak

    • 2.Zurek's 'existential interpretation' assumes environmental interaction structures that cannot themselves be derived from the Schrödinger equation alone.
      ?

      Think about whether this reason is strong or weak

    Reason for 2 of 2
    ?
    • 1.Decoherence suppresses interference terms in a preferred basis but leaves a improper mixture, not definite classical outcomes, as Adler and others have argued.
      ?

      Think about whether this reason is strong or weak

    • 2.An improper mixed state cannot ground the claim that preferred states 'follow the Schrödinger equation undisturbed' since no single branch is selected.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    1 perspective
    Reason against
    ?
    • 1.Preferred states are wave packets that are narrow in position and remain narrow because they are also narrow in momentum.
      ?

      Think about whether this reason is strong or weak

    • 2.States that are narrow in both position and momentum tend to get least entangled with the environment.
      ?

      Think about whether this reason is strong or weak
