The claim that episodic memory is immune to error through misidentification enjoys continuing popularity in philosophy. Psychological research on observer memory—usually defined as occurring when one remembers an event from a point of view other than that that from which he originally experienced it—would seem, on the face of it, to undermine the IEM claim. Relying on a certain view of memory content, Fernández, however, has provided an ingenious argument for the view that it does not. This paper reconstructs Fernández’ argument and shows that there is reason to reject the definition of observer memory and the view of memory content on which it relies. Once these are rejected, it turns out that observer memory does indeed imply that the IEM claim is false.
