@i_petersen One problem with this argument is what I will call the fallacy of decomposition. Mask mandate is not the only possible measure, and each individually may reduce transmission incrementally, say 20% (and infections even less). But add them up and the reduction is far larger.
@i_petersen 这个论点的一个问题是我称之为分解的谬误。强制戴口罩并不是唯一可能的措施，每个单独的措施都可以逐步减少传播，比如说 20%（感染甚至更少）。但是把它们加起来，减少的幅度要大得多。
