(Left) Study 1 average relationships within-pair between a one-unit difference in perceptions of vaccination intentions of others (0 = no one in the group will definitely vaccinate to 6 = all people in the group definitely will vaccinate) on own intention (1 = definitely won’t vaccinate to 5 = definitely will vaccinate) for the pair-matched design (n = 824) and the full valid data (n = 1,992). (Right) Point estimates from the paired design plus 95% CIs created with heteroskedasticity-consistent (HC2) SEs. All P values for the null hypothesis of no effects <0.001, two-tailed.
