The spread of science misinformation harms efforts to mitigate threats like climate change or coronavirus. Construal-level theory suggests that mediated messages can prime psychological proximity to threats, having consequences for behavior. Via two MTurk experiments, I tested a serial mediation process model predicting misinformation sharing from lexical concreteness, through psychological proximity and perceived threat. In Study 1, concrete misinformation primed psychological proximity which, in turn, increased perceived threat. Perceived threat then increased the likelihood that misinformation would be shared. Source credibility was also shown to positively influence misinformation sharing. Study 2 advanced this by showing this process was moderated by subjective knowledge. Specifically, the effect of perceived threat on misinformation sharing was stronger for those with higher subjective knowledge. Furthermore, the indirect effect of lexical concreteness on misinformation sharing was stronger for those with higher subjective knowledge. Results and limitations are discussed within the lens of construal-level theory and science communication.
