Much like how a certain type of person will very strongly defend their musical preferences with various technical reasons, while discounting that it just happens to be what was popular when they were a teenager.
And regarding the music analogy: it's not about the person liking just the music from their formative years, it's that the music they're exposed to during those years has an outsized effect on their preferences going forward. If they pass an intuition check they'll eventually realize the _reason_ why they care so much about the specific technical details they do isn't because that music is inherently and objectively better, and if not then they'll spend the rest of their life complaining about how they just don't make 'em like that anymore.
