I'm wondering if there's a good term for assuming knowledge, or other things, is more common due to my own experience.
Essentially it's like being out of touch with reality, but a little more specific.
One term comes to mind is confirmation bias, but again I don't think it quite matches.
Essentially it's because I've self selected to receive a certain amount of information, I assume it's common knowledge, only to find it isn't.
My personal example is, I repaired a broken kindle screen by replacing it with a new one, and opening up the old kindle.
I assumed a lot of people knew this was a possibility, turns out it they don't. I was surprised to realize this, until I concluded that because I work with technology it's in my sphere of knowledge.
Something about cultural knowledge? Frequency fallacy (I see it a lot, but that doesn't mean it's really frequent) -- Is frequency fallacy a real phrase?
