This study aims to discuss how curiosity affects consumer demand, using local specialty products as an example. This study introduces nostalgia as a intermediary and uses social curiosity and product personality congruence as moderating variables to explore the impact on changes in consumer demand. A total of 794 questionnaires were returned through an online format, and after data analysis, it was concluded that curiosity makes consumers nostalgic; nostalgia positively influences consumer demand. The moderating relationship of explicit social curiosity between curiosity and nostalgia is established, while the moderating relationship of implicit social curiosity and product personality congruence is not established.
