On a fundamental level the recommendation is the wrong way around as a matter of basic physics.
Filters work better under suction than pressure - because they are less likely to leak.
So why have a nonsensical system where everybody has to wear a mask properly all the time and change it regularly in the correct manner just to have any material effect, when an individual that is worried could just wear a better one that filters inbound properly and everybody gets to do what they want.
What's interesting about this is the psychology of why intelligent people have swallowed this. Do they believe the mask is filtering inbound when it isn't? Or is it entirely political - signalling membership of a group to others. Or is it that the perennially worried believe they should have the right to tell others what they can and can't do, when there is a perfectly reasonably 'live and let live' option available.
Why choose a position that divides society when there is one that brings people together?
- FeepingCreature 5y agoI've always heard it as masks being more to protect others during the time where you're infectious but largely asymptomatic. At any rate, you can't prove you're uninfected easily - but masks are trivial to validate.
- neilwilson 5y agoWhy do you need to 'protect others' if their mask works inbound? You have no idea whether you are 'protecting others' or just creating plastic waste for no good reason. Clearly masks are not trivial to validate given that there is no evidence they have any positive effect whatsoever in the real world. No deflection in rates can be seen from NPIs and the process leaks like crazy. It's entirely a backward belief. Believing you are 'protecting others', yet doing nothing to protect yourself against the almost certain risk that other people won't be 'protecting others'. None of it makes any sense in any logical analysis.
- FeepingCreature 5y ago> Why do you need to 'protect others' if their mask works inbound? Huh? You need to protect others because masks (mostly) don't work inbound, that's what I'm saying. (But do work outbound.) > Clearly masks are not trivial to validate given that there is no evidence they have any positive effect Sorry, restate: the presence of masks is trivial to validate.
