On my way back from Turkey, and there’s nothing quite like international travel to help put things into perspective. There are much bigger problems in this world right now than the mask debate.
Still, it would be tragic if people left the emergency thinking one of two extremes: “masks don’t work” or “any mask works.” Another pandemic will come, and we will need to be better and smarter. Hell, every winter, we could be smarter.
This post is to provide a sober perspective on the “story arc” of the science around masks—an attempt to communicate important nuances and provide clarity to a story that is not yet done.
The questionEveryone wants a one word answer to this question: Do masks work? But these three words strung together beg several loaded questions: What does “work” mean? What kind of mask? During what period of transmission? During what disease? In what social context?
All these questions and the answers are getting jumbled together for the public. This may be intentional (to make a point) or unintentional because people really want a simple answer to a complicated question.
Science has been moving at a lightning speed, and we’ve been discovering answers as we go.
<snip - there is much more material and data at the linked website>Where are we going? All of the aforementioned studies have limitations. Every single one. No study is perfect. This is normal. Because of that, we have holes in our knowledge and, as we fill them, evidence will continue to evolve.
We now have the time, data, and energy (maybe?) to understand why, where, and how well masks work, so we can be better and smarter next time.
Bottom lineThe scientific “arc” of mask discovery is ongoing. Science is always evolving. Do not let anyone convince you of a one word answer to the question: Do masks work? It depends.
