C.37.CF:2 - Problem

A new pattern language often adds examples, stops and source returns while changing headings and navigation. Readers then answer better, and the gain is attributed entirely to the language form. Conversely, a terse table can look worse because essential content was removed, not because tables are unsuitable.

The same confusion occurs with a checklist, diagram, executable description or AI-supported presentation. A comparison that changes subject, content, tools and task together can support a useful bundle choice, but it cannot isolate the contribution of one change.
