Maybe we’ve been reading very different breadths of science. Saying masks only work in a small number of situations sounds more like rationalization for not wearing one when we know aerosols are a major source of spread, and that masks significantly reduce aerosol transmission.

1) I don't think its consensus that aerosols are a MAJOR source of spread.

2) Masks are much less effective for aerosols than for droplet transmission. I think the consensus is they at least somewhat reduce aerosol transmission. Only n95 w/o exhale vents that are properly worn are believed to be good at reducing aerosol transmission.

The fact that your glasses fog up shows that surgical masks certainly are very leaky.

aerosols are not a significant source of spread. otherwise, we'd have been inundated with specific stories and studies proving it. distancing overwhelms the effects of masks in nearly all common interaction cases.
