A reconstruction of Jeffrey's notion of ratifiability in terms of counterfactual beliefs

  • Hyun Song Shin


We formalize Jeffrey's (1983) notion of ratifiability and show that the resulting formal structure can be obtained more directly by means of a theory of counterfactual beliefs. One implication is that, under the appropriate formalizations, together with certain restrictions on beliefs, Bayesian decision theory and causal decision theory coincide.
