Test category systems with boundary cases that resist clean classification, as items at category edges reveal missing dimensions, vague boundaries, and incorrect framing more reliably than central members.
Why This Is a Principle

Boundary cases expose where category boundaries are actually located versus where you think they are, similar to how articulation exposes gaps in understanding.
