Why do people not desire to know all their unknowns? Exploring the potential of interest as a factor in arousing curiosity in science
Although previous studies have revealed that knowledge gaps, which refer to differences in what individuals want to know and what they already know, lead to curiosity, students may not experience curiosity for every phenomenon they believe they lack the knowledge of. Herein, we empirically examined the reasons for not feeling curious about the unknown when recognizing science-related knowledge gaps, with a specific focus on interest. Two consecutive studies were conducted. In Study 1, we investigated the association between curiosity arousal and a feeling of interest using the chi-square, Breslow–Day, and Cochran–Mantel–Haenszel tests. In Study 2, we utilized a mixed-method approach to examine whether students’ individual and situational interests could predict curiosity arousal. Twenty-five sixth-grade students participated in Study 1, and six of them participated in Study 2. Based on the results of our study, we observed a robust connection between curiosity and interest, irrespective of students’ level of science curiosity or knowledge gap. Notably, contextualized curiosity, which is aroused when recognizing knowledge gaps within specific contexts, presented a stronger association with situational interest. By contrast, decontextualized curiosity, which is aroused when recognizing knowledge gaps not specific to a particular context, exhibited an association with individual interest. However, interest alone does not account for all instances of curiosity arousal, as indicated by exceptions where it is challenging to attribute the arousal of curiosity solely to interest. We discussed the interpretation and limitations of these results, as well as their implications for education and future research.
