I don't ask people for their IQ score before I spend time with them, but this has held true across the entire cross-section of society that I've personally experienced. When I was working as a dishwasher, everyone would bring small Bluetooth speakers to their area if they wanted to listen to music.
Do you think that people with a certain background / IQ score are not enlightened enough to recognize tinniness or poor sound quality?
You're misinterpreting my comment. I was not implying any correlation between IQs and audiophile-ness. I was pulling out a random example of a counter-intuitive property that "most people" have, though it's clear from your response that I picked a bad example.
I can't claim to speak for everybody, but I think that as high-end (relative to previous standards) audio tech has become very mainstream over the last decade or two, most people recognize that the default phone/laptop speaker setup isn't ideal.
Its actually not true, but is that relevant? Can't a simpleton of IQ 60 be the bearer of golden ears?
You seem to equate variable "measurable puzzle-solving skills" with common sense and capacity to act on a specific domain; please don't do it, because it makes the rest of us feel sorry for you.
