Fig. 5: Affective polarization between vaccination supporters and opponents by group status.

The left panel of this figure shows the predicted level of affective polarization measured as the absolute difference between the thermometer ratings for supporters and opponents (blue) and measured as the difference between the thermometer rating for opponents and the thermometer rating for supporters (magenta) when using a linear regression model with group status (supporters vs. opponents) as main predictor controlling for age, sex, education, opinion-identity, left–right self-placement, income, and language using standard errors clustered at the cantonal level in 2023. Full models are presented in the supplementary material Table 7. The right panel of this figure shows the predicted level of affective polarization measured as the absolute difference between the thermometer ratings for supporters and opponents (blue) and measured as the difference between the thermometer rating for opponents and the thermometer rating for supporters (magenta) when using a linear regression model with group status (supporters vs. opponents) as main predictor controlling for age, sex, education, left–right self-placement, and income using robust standard errors in 2022. Full models are presented in supplementary material Table 9.
