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


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.
