This study examined the effects of repeated instances of underaccommodation (i.e., insufficiently adjusted communication) on people's perceptions and evaluations of communication and speakers. Participants (N = 179) completed a series of three map‐based tasks that required them to follow directions that contained insufficient information. Consistent with hypotheses, as underaccommodation accumulated across tasks, participants inferred less positive motives for the speaker's communication, and inferences about motive for each task contributed directly and indirectly to overall evaluations of both the speaker and their communication. These results indicate that accumulated underaccommodation is consequential, and underscore the theoretical importance of motive attributions to predicting reactions to underaccommodation.
