Here's one quote from one of the articles posted by Casdon.
"Compared to villages that didn't mask, those where masks of any type were worn had about 9% fewer symptomatic cases of COVID-19. The finding was statistically significant and was unlikely to have occurred by chance alone."
So, 9% effective. My mind works the other way, and I choose to say 91% ineffective, i.e. worthless and useless. And I've seen that they don't work with my own eyes - that is perfectly good enough proof for me and I shall continue to not wear masks.
Like I said at the beginning, it is socially irresponsible to perpetuate the myth that these things in any way make people safer - they don't.
In the article which you yourself posted LilacChaser it states:
"Lab studies have shown that surgical masks, such as N95’s, block around 95 per cent of aerosol-sized particles."
So I don't know where you get the idea that masks are 91% ineffective.
A good mask will protect you and those around you in the majority of cases. That's good enough for most right-minded people, who will hopefully carry on wearing them.
