A little shot of humility: Intellectual humility predicts vaccination attitudes and intention to vaccinate against COVID‐19

Huynh, Ho P.; Senger, Amy R.

Vaccinations remain a critical, albeit surprisingly controversial, health behavior, especially with the promise of widely available COVID‐19 vaccine. Intellectual humility, a virtue characterized by nonjudgmental recognition of one's own intellectual fallibility, may counter rigidity associated with anti‐vaccination attitudes and help promote vaccine‐related behaviors. This study investigated whether intellectual humility is related to anti‐vaccination attitudes and intentions to vaccinate against COVID‐19, and whether intellectual humility can predict unique variance in these outcomes beyond participant demographic and personal factors. Participants (N = 351, 57.23% male, mean age = 37.41 years, SD = 11.51) completed a multidimensional measure for intellectual humility, the anti‐vaccination attitudes (VAX) scale, and a two‐item COVID‐19 vaccination intention scale. Bivariate correlations demonstrated that intellectual humility was negatively related with anti‐vaccination attitudes overall, r(349) = −.46, p < .001, and positively related to intentions to vaccinate against COVID‐19, r(349) = .20, p < .001. Hierarchical multiple regression revealed that intellectual humility predicted all four types anti‐vaccination attitudes, overall anti‐vaccination attitudes, and COVID‐19 vaccination intentions above and beyond demographic and personal factors (i.e., sex, race/ethnicity, age, education, socioeconomic status, and political orientation), ΔR (2) between .08 and .18, ps < .001. These results bolster intellectual humility as a malleable psychological factor to consider in efforts to combat anti‐vaccination attitudes and promote COVID‐19 vaccination uptake.
