The author draws attention to a feature of judgments expressible using indexical terms such as I, here and now and the significance this feature has for discussions of Immunity to Error through Misidentification (IEM). He mainly focuses on spatial indexicals because there are certain kinds of error that occur in perception-based spatial judgments that occur more rarely, if ever, for judgments about times or places. Perception-based demonstrative judgments are often claimed to possess IEM. The author identifies two kinds of immunity to error: the IEM and IEMC, and suggests that indexical judgments typically possess one but not the other, according to whether the nominal term associated with the indexical has the judged or stipulated role. He also suggests that while both kinds of role are possible, at least in principle, for spatial and temporal judgments, for first-person judgments the nominal term always has the stipulated role.
