Before revision:  The linear contraction parameter captures the DM's relative inclination towards ML with respect to FB, hence ML and FBare the two extreme special cases of RML. More importantly, characterization of conditional preferences given by RML updating is provided when the preferences are represented by the Maxmin Expected Utility  .
