Abstract

This paper examines vaccination as a descriptive social norm in the context of the Covid-19 pandemic. Using a large-scale survey experiment in Turkey, we first elicit respondents’ vaccination attitudes and show that political affiliation is a strong predictor of it. We then use economic games to measure the extent of outgroup discrimination induced by respondents’ attitudes towards vaccination. We find that while both pro- and anti-vaxxers discriminate against each other substantially, the pro-vaxxers discriminate more than the anti-vaxxers do. This polarization intensifies when pro- and anti-vaxxers perceive a political difference between them. Using randomized informational treatments, we show that a reminder or priming of external threats, appealing to a broadly shared social identity, might mitigate such outgroup discrimination.
