In 2019, a Yale University study found that people would believe a single source of misinformation if it was repeated across many channels—but the University of NSW (UNSW) decided to see if this was true.


This article by Diane Nazaroff, writing for UNSW Newsroom, makes the following points:
  • Yale University researchers found that people would give more credence to advice if that advice were repeated across media and social media sources.
