...Rachael Briggs It is a platitude among decision theorists that agents should choose their actions so as to maximize expected value. But exactly how to define expected value is contentious. Evidential decision theory (henceforth EDT), causal decision theory (henceforth CDT), and a theory proposed...

... unconditional assign- ment of credences to dependency hypotheses in determining the rela- tive values of actions. If the Hs form a partition of the worlds that the agent assigns nonzero credence, the value assigned to an action A by evidential deci- sion theory (henceforth EDT) is given...

... of causation, however, we seem to lack an uncontro- versial analogue of SDT. On the contrary, subjectivist evidential decision theory (EDT), such as that of Jeffrey (1965)—though initially motivated by the desire to extend Savage’s SDT to the case in which outcomes may depend on an agent’s choices...
