I think all design choices are made relative to a prioritized set of values. I think good design process makes these values explicit, consciously deciding which aesthetics supersede others, who to support, who to exclude.
I agree with Ko here regarding how "all design choices are made relative to a prioritized set of values", but my next question is when do you realize you're consciously deciding which aesthetics supersedes others? Like Ko said, making your values explicit is important when it comes to aesthetics since it can be very subjective, so I think that it's difficult to determine which layouts, colors, font choices, frameworks, etc., is "better" than another one. When does one usually come to terms that one design is better than another? I'd like to think this coincides with design justice; I don't think there is going to be a design choice that fulfills the needs of everyone.
