Exploring vaccine hesitancy: the twofold role of critical thinking

With the progress of the vaccination campaign against the SARS-COV-2, we are ever closer to reaching that part of the population that refuses or is hesitant about vaccination. This study investigated the association between critical thinking motivation factors (i.e., intrinsic value of critical thinking and expectancy of one’s critical thinking ability), conspiracy mentality, intolerance of uncertainty and hesitancy toward vaccination. A sample of 390 participants completed an online survey during April 2021. Across participants, results indicate that conspiracy mentality and expectancy about personal ability as a critical thinker positively predict vaccine hesitancy. On the contrary, the intrinsic value attributed to critical thinking, intolerance of uncertainty, and education are negatively associated with hesitancy. While the findings confirm existing evidence, particularly on the detrimental role of conspiracy mentality on vaccine acceptance, they also shed light on the double-faced role exercised by critical thinking. Practical implications and future directions are discussed. SUPPLEMENTARY INFORMATION: The online version contains supplementary material available at 10.1007/s12144-022-04165-w.
