When part of the environment responsible for decoherence is used to extract
information about the decohering system, the preferred pointer states rema
in unchanged. This conclusion-reached for aspecific class of models-is inve
stigated in a general setting of conditional master equations using suitabl
e generalizations of predictability sieve. We also find indications that th
e einselected states are easiest to infer from the measurements carried out
on the environment.
