Two Paradoxes of Rational Choice Jeffrey Desirability Probability and desirability of counterfactuals Representations Counterfactuals Preference actualism and desirability maximization Modelling Allais's and Diamond’s preferences Counterfactual-Dependent Preferences Independence and additive separability Ethical actualism Expected utility, separability, and ethical actualism Ethical Actualism and Separability Concluding Remarks Appendix The desirability of what actually occurs is often influenced by what could have been. Preferences based on such value dependencies between actual and counterfactual outcomes generate a class of problems for orthodox decision theory, the best-known perhaps being the so-called Allais paradox. In this article we solve these problems by extending Richard Jeffrey’s decision theory to counterfactual prospects, using a multidimensional possible-world semantics for conditionals, and showing that preferences that are sensitive to counterfactual considerations can still be desirability-maximizing. We end the article by investigating the conditions necessary and sufficient for a desirability function to be a standard expected-utility function. It turns out that the additional conditions imply highly implausible epistemic principles.
