The Relationship between Infection-Avoidance Tendencies and Exclusionary Attitudes toward Foreigners: A Panel Study of the COVID-19 Outbreak in Japan
Amidst an outbreak of COVID-19 in January 2020, this study, which based on the behavioral immune system, focused on the preventive behaviors related to COVID-19 infection and Japanese people’s exclusionary attitude toward foreigners, examining the time-series changes associated with the spread of the novel coronavirus in Japan, which was one of the first countries to confirm cases outside China. Also, we examined the effects of individual differences in infection-avoidance tendencies and the frequency of people’s daily contact with foreigners. In late January, mid-February, and early March of 2020, this study conducted a panel survey 1,004 Japanese citizens aged 18 years or above living in Japan, and who had registered with the crowdsourcing service. The results indicated that as the spread of COVID-19 increased, tendencies toward infection-preventive behaviors increased, and exclusionary attitudes toward foreigners became stronger. Similarly, the avoidance response against unfamiliar people, including Japanese strangers increased. No relationship between the increased risk of infection and the Japanese respondents’ exclusionary attitudes toward the Chinese but were more negative than that for other groups. However, it is difficult to conclude that all the reported exclusionary behaviors and attitudes were irrational or excessive false-positive errors. People with strong infection-avoidance tendencies engaged in more preventive actions, regardless of whether they were living under normal circumstances or under threat of infection, and they indicated strong exclusionary attitudes toward foreigners in general and the Chinese specifically under threat of infection. We observed a moderating that the higher the frequency of daily contact with foreigners, the weaker the exclusionary attitudes toward them. This study recorded the behavioral and psychological states of people in Japan during the 40 days preceding the WHO’s 11 March 2020 declaration of the COVID-19 pandemic. The data collected in Japan, where the infection spread widely early on, will provide valuable insights for countries anticipating significant social changes.
