Vortrag: „COVID-19 Health Certification Reduces Outgroup Bias: Evidence from a Conjoint Experiment in Japan“ (Yoshiaki Kubo, Isamu Okada)
22. November 2021 @ 11:00 - 12:00
Psychological theorem supposes that serious threats cause negative attitudes by ingroups to outgroups, i.e., outgroup bias. For example, the behavioral immune system theory claims a chain reaction from infectious threats to outgroup bias as the human defense against pathogens. However, what reduces outgroup bias from threats to health caused by a pandemic is unknown. This study deals with this missing argument by focusing on threats to health by COVID-19, which have caused negative attitudes toward racial/ethnic groups, immigrants, or tourists worldwide. In particular, this study provides evidence that health certifications to prove immunity or negativity for COVID-19 contribute to reducing the outgroup bias. Using a discrete choice experiment with a randomized conjoint design in Japan, we investigated public attitudes toward inbound travelers entering the country, including foreigners, immigrants, or tourists. We found that those inbound travelers carrying a health certificate have a higher probability of being admitted entry by host residents: a vaccination certificate by 31 percent and a negative certificate by 27 percent. These effects are the same size as those travelers undergoing self-isolation. Our results demonstrate that health certifications can mitigate outgroup bias among ingroups facing threats to health by COVID-19. We anticipate our study to support the introduction of a vaccine passport, which is often denied in terms of inequality between vaccinated and unvaccinated individuals. At the same time, especially for unvaccinated travelers, this study suggests that a negative certificate can be an alternative to a vaccine passport.
