It is hard — re: "when you look out the window or when you’re out in your N95 and see 99% of the population going about things as if there’s no pandemic."
It helps me to remember that what we see outside is factually not 99%, just our own anecdotal sample. Some larger than others: I live in one of the most populated, traveled-to cities in the world and see a royal shit-ton of people every time I go outside — yet another reason I join the few masking.
(I get it that in other, less crowded places things look different; that's a contributor to confusion online. My city problems may not make sense to someone in the suburbs, but we're in the same discussion without any context.)
OTOH, I look at the data and know that outside, I won't see the invisible others. Those who are IC, have LC, etc. Of course they/we group online, since that's the only place to safely be and discuss.
I also know that people, even those who are informed, value social norms. E.g. Dr. Fauci going to some event and removing his mask because others were, then getting covid. And here's a good thread: https://twitter.com/Helenreflects/status/1641003804584972289
So I think a combination of a few factors contribute to those still masking; any single one may not be enough:
being closer to the nonconformist end of the spectrum to begin with (i.e. "I care about people; less so what they think.")
being informed, scientifically-literate
cultural (conforming, but to a different group)
those who've experienced chronic illness (not just the physical aspects but also how others react short and long-term...
and the resulting distrust built up from that: lack of, or lack of trust in the strength of safety nets — social and financial
likewise, those who've experienced gaslighting (this term is overused lately, but having experience with that can lead to personal high valuation of fact-checking and record-keeping, and again a lower regard for what some others are doing or saying)
privilege / circumstances (e.g. it may be harder for someone with kids; they might be more likely to be more fatalistic if it seems insurmountable. or e.g. this person's BF who probably felt high pressure due to this mandatory work event: https://www.reddit.com/r/WitchesVsPatriarchy/comments/11h3ciu/comment/jart4aj/?utm_source=reddit&utm_medium=web2x&context=3)
