[Medical misinformation on social media: should it be corrected or not?].

A lot of medical misinformation circulates on the Internet - especially social media. During the corona crisis, this became an acute and prominent problem. Countering medical misinformation can be done with debunking (refuting misinformation with fact checks) and prebunking (warning people about misinformation and teaching them to recognize it). Research shows that debunking helps correct misconceptions created by misinformation, although the effect is limited. Although this is sometimes suggested, it is not true that corrections or factchecks actually cause misconceptions to be reinforced. Prebunking is also effective, although it can also cause people to distrust reliable information as well.
