In theory, a randomized controlled study would test the spread of the virus among people wearing masks versus people not wearing masks and possibly scientifically demonstrate the effectiveness of wearing one.
“I would not want to do a randomized controlled study because that would mean having people not wear masks and see if they do better,” he said.
Fauci suggested he would never ask an individual to participate in a study that would involve not wearing a mask.
“I think that to do the study would be kind of difficult to do because then you’d have to tell people not to wear masks, and I’m not about to tell them that,” he said.
