Strictly speaking we're both in violent agreement that really high quality studies are required for the evidence to be solid.

Please note that I did not say there was scientific evidence for masks, but that wearing masks is good is the mainstream scientific position (which changed only very recently).

I read your article. It's pretty limited in its analysis. I'm going by this popular science article from my alma mater (I have a PhD in biophysics), https://www.ucsf.edu/news/2020/06/417906/still-confused-abou...

The article you cited doesn't include a number of the articles my article mentions (http://files.fast.ai/papers/masks_lit_review.pdf, https://www.healthaffairs.org/doi/10.1377/hlthaff.2020.00818 https://www.researchgate.net/publication/342198360_Associati..., https://www.cmaj.ca/content/192/15/E410, https://www.washingtonpost.com/business/2020/06/17/masks-sal...,

More importantly- this is a situation where we don't have unambiguous data, but the mainstream position is consistent with the current data and reasonable thinking about disease prevention.
