Design information systems that actively surface relevance…

Why This Is a Principle

This principle derives from Goals as Perceptual Filters (goals define relevance as signal-detection criteria), Signal detection involves independent dimensions… (signal detection involves independent dimensions), and Every detection system faces a fundamental tradeoff between… (detection systems face a fundamental tradeoff). It prescribes a design approach—build systems that detect signal rather than filter noise—which is actionable and general enough to apply across many information contexts. It's clearly derived from foundational truths about perception and signal detection, not itself foundational.
