BACKGROUND The ongoing coronavirus pandemic is an unprecedented global health crisis. Because large-scale behavior change has been critical to slowing the spread of the virus, understanding the mechanisms behind people’s decisions and behaviors to follow (or not) public health recommendations, is essential. OBJECTIVE In order to investigate one possible mechanism, we investigated the presence of the better-than-average effect. METHODS in 3066 individuals across Poland, Iran, and Kazakhstan. RESULTS Participants demonstrated clear the BTAE in all three countries. Furthermore, we found that the level of BTAE was a predictor of COVID-19 vaccination (declarative) claims. CONCLUSIONS These findings contribute to the growing literature on the role of cognitive biases on health behaviors, particularly during global health emergencies. We provide recommendations for public health communicators on how to address this bias to help ensure people adopt the behaviors that are critical to combatting the virus.
