Yeah it’s all perception, but cultivating the right perception is vital to effective, productive communication.
Polished things have a context of "use", not "evaluate", because we use so many polished things every day, but very rarely have any need to evaluate them (mostly only when we're buying them, or when a repair person asks us to describe what's wrong with them.) Whereas unpolished things are mostly "for" evaluating; it's rare that people use unpolished things (outside of, say, disaster-relief infrastructure.)
Does this really imply “humans are broken”? We all have limited resources and I think this could just be a first order prioritization mechanism. Of course one has to be aware of the bias but that’s a different problem.
