Pretty much every study agrees, cloth masks are not as good as n95 or surgical masks. They don’t however say that cloth does nothing. Also I have not been able to find even 1 study that looked at multilayer cloth masks. Some even state that multilayer would probably do much better than single layer, but they weren’t even going to test them to see. Pretty much every study is focused on how well masks protect the wearer, but very few focus on how well they protect others from you. The only study that I found that does talk about it, says that while less than n95 masks, that even cloth masks have a significant affect on your spreading of the virus.
Just out of curiosity, what is a real scientist?
The one that aligns with and confirms your personal bias; as all real science works.
Someone that takes in data and comes to a data driven conclusion, not an ideological driven solution.
