This study, published in PNAS, investigates how references to scientific entities, termed Scientific Authority Cues, influence the spread of misinformation on social media. The researchers demonstrate that when false or misleading posts include mentions of scientific sources, institutions, or terminology, users are more likely to share them without verifying their accuracy. This suggests that the perceived legitimacy conferred by scientific references can be exploited to facilitate the unintentional propagation of misinformation.
