Most men don't care about quality audio either, so let's say, most people. They like "music" and so long as it's what they like, they aren't concerned about the sound quality, just the song.
I believe people are generally average in tastes and perception, but much of this is learned behavior by conformity. Everything is "ok" and therefore is sufficient. Some percentage will develop deeper interest in something, food, beer, cars, music, film, books, etc. and become more discriminating in their thing of choice. But societal norms and pressures skew a lot hence cars are a "guy" thing and sewing is a "girl" thing. People end up letting those norms dictate their lives consciously or not, unfortunately. Others follow their hearts regardless, man or woman and pursue happiness.I
Moral of the story, open your mind to everything and enjoy what you like, not what society says or thinks you should.
