Still strict Bayesians display a special fascination for black box interpretations of sets of probability distributions. 2Giirdenfors and Sahlin (1982a) derive the recommendations allowed by the permissibility interpretation of credal states from a decision theory that exploits sets of probability Thus, when belief states are represented as sets of probability distributions under the permissibility interpretation, there are implications ensuing for rational choice which strict Bayesians cannot countenance even Thesis 2: Jeffrey's sets of distributions can be given a black box interpretation; but then the set of probability distributions cannot be "naturally identified" with (i.e., represent) the belief state. ./cache/work_mevw4vudavasnh3e26u6ahv4ke.pdf ./txt/work_mevw4vudavasnh3e26u6ahv4ke.txt
