Audit what your classification system discards by explicitly
Audit what your classification system discards by explicitly listing the information lost in each category compression, then check whether any discarded dimensions matter for decisions the system supports.
Why This Is a Principle
Derives from Abstraction Necessarily Discards Information (abstraction necessarily discards information) and Goals as Perceptual Filters (goals define relevance). The principle prescribes explicit examination of what's lost in compression to verify it aligns with goal-relevant distinctions.
