This just in: No good evidence, anywhere, that masks help A recent review looked at 67 randomized trials of mask use and other mitigation measures, coming up with zero statistical significance of effectiveness of masks against viral respiratory infection. -------- The pooled results of randomised trials did not show a clear reduction in respiratory viral infection with the use of medical/surgical masks during seasonal influenza. -------- Interpretation: No good evidence exists, anywhere, that masks help (just like Senator Rand Paul has been saying). We have been asked to believe in a medical mythology (a story where there is no good evidence to back up that it is true). This is not different from tribes who are asked to believe that their rain dancer is the person who brought rain. The tribal leaders always point out that the dancer was dancing a few days before the rains came, and they ask everyone to just "believe" the dancing is "why" the rain came. Experts in the 21st century should be more professional than that, however. As 2020 shows, many if not most of them are not more professional, though. They are no better than tribal witch doctors willing to make pronouncements which potentially harm millions. We should not listen to them about whether to mask up or lock down. Experts who cannot provide evidence to back up their claims should not be listened to. Source Physical interventions to interrupt or reduce the spread of respiratory viruses.
