Curiosity is a powerful determinant of behavior. The past decade has seen a surge of scientific research on curiosity, an endeavor recently imbibed with urgency by the WHO, which set managing information-seeking as a public health goal during pandemics. And yet, a fundamental aspect of curiosity has remained unresolved: its relationship to utility. Is curiosity a drive towards information simply for the sake of obtaining that information, or is it a rational drive towards optimal learning? We leveraged people’s curiosity about COVID-19 to study information-seeking and learning in a large sample (n=5376) during the spring of 2020. Our findings reveal that curiosity is goal-rational in that it maximizes the personal utility of learning. Personal utility, unlike normative economic utility, is contingent on a person’s motivational state. On the basis of these findings, we explain information-seeking during the pandemic with a rational theoretical framework for curiosity.

The COVID-19 pandemic has highlighted the importance of understanding and managing information seeking behavior. Information-seeking in humans is often viewed as irrational rather than utility maximizing. Here, we hypothesized that this apparent disconnect between utility and information-seeking is due to a latent third variable, motivation. We quantified information-seeking, learning, and COVID-19-related concern (which we used as a proxy for motivation regarding COVID-19 and the changes in circumstance it caused) in a US-based sample (n = 5376) during spring 2020. We found that self-reported levels of COVID-19 concern were associated with directed seeking of COVID-19-related content and better memory for such information. Interestingly, this specific motivational state was also associated with a general enhancement of information-seeking for content unrelated to COVID-19. These effects were associated with commensurate changes to utility expectations and were dissociable from the influence of non-specific anxiety. Thus, motivation both directs and energizes epistemic behavior, linking together utility and curiosity.
