Institutional quarantine and dishonest behavior

Quarantine has been implemented worldwide to mitigate the spread of infectious diseases such as COVID-19. Although recent literature has outlined the mental and psychological costs of quarantine, its ethical costs are not fully understood. In two online experiments conducted during an institutional quarantine event (481 participants), we find that institutional quarantine leads to more dishonest behavior, including lying about the outcome of a random-draw task and overreporting one’s performance in a real-effort task to gain financial benefits. By directly manipulating individuals’ perceived psychological ownership, we provide suggestive evidence that psychological ownership may be one mechanism underlying the relationship between institutional quarantine and dishonest behavior. A complementary experiment (226 participants) suggests that anxiety and frustration may also serve as explanatory factors for this effect. We then discuss the implications of our findings, which may inspire approaches to mitigate the negative effects of institutional quarantine on honesty.
