As information technologies, such as artificial intelligence, that influence human values spread throughout society, efforts to align human values with technology-supported values are expanding. While values were traditionally treated as static design goals, user values can shift during interaction. Focusing on web search, we quantified three values considered important—“search accuracy,” “access to diverse opinions,” and “access to safe information”—as the indicators of diversity, fairness, and frequency. We developed a search system that allows users adjust the weights assigned to these indicators and conducted a five-week evaluation. Weekly questionnaires and post-experiment interviews with nine participants examined changes in their preferences for the three indicators. The preferences of three participants clearly changed week by week, and reasons for the change included not only ease of use but also reflection on the meaning of the values themselves. These results suggest that values during the use of information technology are not static but evolve through a multi-stage process, indicating the need for system design that considers user self-reflection.
