The article is about pollution: that's a cost. Conformity over something that doesn't work: that's a cost. Fear: that's a cost. Not being able to relate to other human beings using our facial expressions the same way: that's a cost. > Masks are effective at helping an infected wearer reduce spread to others. This is not exotic science There is literally no Science to bake that up. It's literally superstition. BMJ Published research saying they're not effective: https://bmjopen.bmj.com/content/bmjopen/5/4/e006577.full.pdf https://bmjopen.bmj.com/content/bmjopen/5/4/e006577.full.pdf Cambridge says they should only be used as a last resort: https://www.cambridge.org/core/services/aop-cambridge-core/content/view/0921A05A69A9419C862FA2F35F819D55/S1935789313000438a.pdf/testing_the_efficacy_of_homemade_masks_would_they_protect_in_an_influenza_pandemic.pdf https://www.cambridge.org/core/services/aop-cambridge-core/c... and most recent was the 6,000 person study from Denmark which came to the same conclusion: they do not work.

This is from your source: "The findings of the study found that adherence to mask use significantly reduced (95% CI, 0.09-0.77;P5.015)the risk for infection associated with influenza-like illness" https://www.cambridge.org/core/services/aop-cambridge-core/content/view/0921A05A69A9419C862FA2F35F819D55/S1935789313000438a.pdf/testing_the_efficacy_of_homemade_masks_would_they_protect_in_an_influenza_pandemic.pdf https://www.cambridge.org/core/services/aop-cambridge-core/c... "A protective mask may reduce the likelihood of infection, but it will not eliminate the risk, particularly when a disease has more than 1 route of transmission. Thus any mask, no matter how efficient at filtration or how good the seal, will have minimal effect if it is not used in conjunction with other preventative measures, such as isolation..." Cambridge doesn't say masks don't work. You talk as if masks are as effective as dowsing rods and mask-wearers have been duped.
