简要总结
In the Contagious Misinformation Trial the investigators aim to debunk prevalent misinformation about an infectious disease using two evidence-based methods of debunking. The two debunking methods are packaged in two audio dramas of 4 episodes each, which will be sent to the WhatsApp of participants who are randomised to intervention group 1 or 2. The control group will receive audio messages about a different topic. The primary outcome is the reduction in belief in two misinformation statements about the infectious diseases.
