Remembering through discourse between witness and inquisitor was discussed from the viewpoint of daily joint-remembering study. Discourse-analysis of remembering revealed dynamics, which is peculiar to joint-remebering. Specifically, the logic of inquisitor (=listener), who did not experienced original event, had an influence on remembering of witness. This logic was based on “general rationality”. It was suggested that such rationality can leads inaccurate remembering. Especially, in the case where the original event has manifold meanings that make it difficult to put into words, such inaccuracy will be great. Furthermore, a dichotomy of input style distinguished by it's intention and aim, “storage-focused input” / “output-focused input”, was proposed. It seems this difference in input style influences their storage and output. The storage by “output-focused input” must be categorized more clearly and solidly than that by “storage-focused input”. Therefore, the storage by “output-focused input” will be put into words more easily than that by “storage-focused input”. This is significant in a joint-remembering situation as stated above. In other words, the difference between “storage-focused input” and “output-focused input” influences the possibility of leading inaccurate remembering in a joint-remembering situation.
