No you are incorrect..."a wealth of research" is not a definitive clearing house of facts... there are only findings when it comes to the actual virus within the droplets that the research is akin to...yes you can say the droplets do this or don't do that but you can't say what happens with the covid microbes...
And as far as masks being "effective" there are NO definitive numbers...especially in real life scenarios not laboratory and emulated conditions and settings...
You need to face some facts that just because you want to believe something just because there is "some" evidence that supports it...does not make it so...
And BTW...vetted by whom??
You seem to be expressing that you will only be "convinced" when you put a sick person in the same room as a healthy person, don't let them touch, rather only talk, and then see if the other gets infected. That would actually be a good experiment. The problem is, it would never be approved for ethical reasons. So, you look at data that you do know, and again (like a puzzle) piece everything together to get a clear picture.
It is pretty safe to say that pretty much no research is "definitive". I admitted to as much earlier. That's how science progresses. But claiming "I refuse to believe" when there is overwhelming evidence is naivety at best, or worse, willful ignorance.
Now, as to your argument of a "wealth" of evidence versus "some". Well, just because you aren't familiar with it, doesn't mean hasn't been performed.
So, let's take a look at the mask issue. What do we know?
The virus is shed from the upper respiratory tract (
Virological assessment of hospitalized patients with COVID-2019 | Nature), which is the same location droplets are produced during speaking/coughing/talking (
Modality of human expired aerosol size distributions - ScienceDirect,
https://journals.plos.org/plosone/article/comments?id=10.1371/journal.pone.0227699, etc.). Droplets are in the range of 0.5 micron - 200 micron (
Modality of human expired aerosol size distributions - ScienceDirect,
Effect of voicing and articulation manner on aerosol particle emission during human speech). It has been shown that viruses that are shed in the respiratory and oral tract can be transported in expirated droplets (
https://pubmed.ncbi.nlm.nih.gov/25523206/). Side note: this was first shown in 1897!!!! Expiration droplets are known to be able to stay suspended easily, for hours, and up to days in time (
https://www.sciencedirect.com/science/article/pii/S0021850208002036,
https://www.pnas.org/content/115/5/1081,
https://pubmed.ncbi.nlm.nih.gov/17542834/, etc.). The SARS-CoV-2 virus remains viable (infectious) in an aerosolized form for up to 2 hours (
https://www.nejm.org/doi/10.1056/NEJMc2004973). The virus has been measured directly in hospital locations where infected patients are not present, as well as in social situations (e.g. Skagit choir) where social distancing was maintained, no contact occurred, but transmission did occur (For a review of some of these examples - there are many - see
https://academic.oup.com/cid/advance-article/doi/10.1093/cid/ciaa939/5867798,
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7151430/,
https://www.medrxiv.org/content/10.1101/2020.06.15.20132027v1.full.pdf, etc.). Finally, in addition to the summation of information already presented, it is known that oral expirations can travel much farther than 6 feet in aerosolized form (
https://jamanetwork.com/journals/jama/article-abstract/2763852).
The usefulness of face masks has been proven in the laboratory, and in the community, despite your protestation to the contrary that they haven't. Again, just because you aren't aware of the results doesn't mean they aren't out there. (see below)
Face coverings work, because they stop virus-laden droplets from entering the surroundings by trapping them in the cloth (

https://www.nature.com/articles/s41591-020-0843-2?ContensisTextOnly=true,
https://pubs.acs.org/doi/pdf/10.1021/acsnano.0c03252,
https://aip.scitation.org/doi/full/10.1063/5.0016018,
https://www.sciencedirect.com/science/article/pii/S0021850220301063, etc.) The usefulness of face covering has also been proven by looking at how infection rates vary with state mandates on mask wearing (
https://www.healthaffairs.org/doi/full/10.1377/hlthaff.2020.00818). Retrospective community modeling based on facemask compliance has shown similar results (
https://www.sciencedirect.com/science/article/pii/S2468042720300117). Wearing face masks will save a large number of lives (
https://www.sciencedirect.com/science/article/pii/S2468042720300117). The need for everyone to wear a face masks is because of the prevalence of asymptomatic and presymptomatic spread with COVID-19 (I already posted a bunch of links to articles proving this in an earlier post).
Now, the sad thing here? I have just scratched the surface of what is out there. Yes, the evidence, when taken as a whole, is
overwhelming that: (1) Aymptomatic and presymptomatic individuals can spread the virus in aerosol form. (2) The virus is airborne and infectious. (3) Masks are effective (but not perfect) at stopping the airborne spread of the virus. (4) If everyone wears a mask, it will save lives.
The facts are before you. But hey, sometimes it's easier to just play ostrich, bury your head in the sand, stick to your guns, and continue in ignorance.
