| Consequential choice and incomplete evidence | State what the evidence supports and obtain only the missing contribution that can change the decision. |
| Comparable treatment and attainable demonstration | Comparable opportunity may require a qualified accommodation rather than identical irrelevant conditions. |
| Actual assisted work and independent capability | Test the required configuration; add unaided performance only for a justified work condition. |
| Speed and validity | A fast, inexpensive procedure is useful only for an inference it can support. |
