| Discovery | A useful problem can emerge during inquiry, while retrospective enthusiasm can be mistaken for evidence of need. |
| Receiver relevance | The receiver can explain a missing result, while effects on others and protected conditions may defeat the proposed change. |
| Specificity | A contribution must be inspectable, while premature solution detail narrows the opportunity. |
| Value and feasibility | A problem may be worthwhile before its solution is reachable; neither claim establishes the other. |
| Promise and benefit | An offer can specify a result, while its usefulness, provision, and downstream effects require separate grounds. |
| Plurality | Different receiving problems may remain live without being forced into one same-result comparison. |
