I think some of it is believing misinformation, and the rest is just plain stubbornness (excluding those with medical reasons not to, of course).
1) virus is highly contagious 2) unvaxxed run around without care
So how has it not propagated through everyone after months (of delta), at least in those areas with lower vaxxed rates? I'm thinking there is some form of at least social distancing preventing this.
Edit: The only "irrational covid behaviour" is the mass hysteria around it.
