It's required to wear a mask 100% of the time in some medical professions. This is usually so you don't get vulnerable people sick, not to protect yourself. Medicine is highly evidence based. If masks didn't work these rules wouldn't exist.
Most of those wearing masks aren't doing it out of "fear and emotion", they're doing it to protect others. We all know that cloth style masks everyone is wearing offer the wearer almost no protection. The value is primarily in the protection they provide to others by blocking aerosols when you breathe and talk.
I get the feeling you follow some news sources that erroneously claim people wear masks to calm their fear and emotions
But you might be surprised to learn that even as recently as 2016 the use of masks in surgical settings wasn't understood to be backed by very strong science: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4480558/
This article is about surgical masks which are basically tissue paper not N95's. In some healthcare settings N95 is required especially when dealing with immunocompromised or extremely infections diseases like active TB or SARS. The evidence for these is much stronger
In Japan: they'd be worried about infecting others so they would wear a mask.
In USA: Even if they cared about other and could buy a mask, they'd be worried about the weird looks, so they don't wear a mask.
Hopefully in 2026, assuming Covid is solved by then, people wearing masks in the US won't be looked weirdly, or even if people like you do, the sick people would think "Why should I give a shit what you think.".
This behavior can be suspended temporarily on a short-term basis when a population perceives an urgent state of pandemic or (as in Japan) when an individual says he has a cold, but it may not be sustainable at a society-wide scale beyond that. Seatbelts faced cultural resistance before adoption, sure, but much less than masks would once the acute COVID risk has passed.
What wearing the mask does show me is that a person is extremely susceptible to propaganda and likely has conformist tendencies. This isn't necessarily true in all cases but I think it will be for the majority of them. This sort of person is dangerous to bring in to your social circle because they can easily be manipulated into being an instrument of the state. I don't want to have to police my own thoughts and opinions in front of my friends and in an increasing totalitarian "cancel culture" environment this risk becomes increasingly more substantial and existential.
And you should tell frontline medical personnel that masks don't protect them, they'll be glad your non-conformist ultra intelligent mind managed to figure it out.
What are you basing this assessment on? Are all masks equal? Does training in mask application matter? For what duration are different types of masks effective?
They do get less effective with time, exposure to moisture. Using alcohol to clean an N95 will significantly reduce its effectiveness.
Early on, Stanford did a study on various methods of sterilizing N95s and the change of effectiveness. Heat (70°C for 30 mins) was best.
