Observer free choice in quantum mechanics?

    Does quantum mechanics allow an observer free choice of measurement?

    Interactions with the invironment tend to "push" a physical system into an eigenstate of some observable. I guess you can call this a "measurement" without an observer.

    This is what "decoherence" is all about.
