This five-decade longitudinal study reveals that vaccine resistance and hesitancy are rooted in deep-seated psychological histories rather than simple misunderstandings. Key predictors include adverse childhood experiences, long-standing mental health struggles, and specific personality traits like nonconformism, fatalism, and high negative emotionality. Furthermore, many resistant individuals faced cognitive challenges in processing complex health data. These findings suggest that vaccine attitudes are established well before adulthood, highlighting the need for early childhood education and tailored messaging that accounts for these lifelong cognitive and emotional frameworks.

Applying a Lewinian interactionist framework, this study examined how both government policy and personality traits influenced sheltering-in-place behavior across 54 countries. Researchers found that while strict government policies effectively increased compliance, individual personality traits remained significant predictors of behavior. Specifically, high levels of Openness, Conscientiousness, Agreeableness, and Neuroticism were linked to staying home, while Extraversion was associated with lower compliance. Notably, the influence of Openness and Neuroticism weakened as government restrictions became more stringent, suggesting that while personality drives behavior in flexible environments, strong external policies can partially override these internal tendencies.
