 Thus far the focus has been on prominent versions of the standard theory of rational choice: EU theory. This section picks up on some key criticisms of EU theory that have been developed into alternative accounts of rational choice. The proposed innovations to the standard theory are distinct and so are discussed separately, but they are not necessarily mutually exclusive. Note that we do not address all criticisms of EU theory that have inspired alternative accounts of rational choice. Two major omissions of this sort (for want of space and also because they have been thoroughly addressed in alternative entries of this encyclopedia) are i) the problem of causal anomalies and the development of causal decision theory (see the entry on  causal decision theory),  and ii) the problem of infinite state spaces and the development of alternatives like “relative expectation theory” (see the entries on  normative theories of rational choice: expected utility theory  and  the St. Petersburg paradox).
