C.11.DUA:5.2 - A completed choice with conditional inquiry content
A research team chooses among feasible plans A, B and C. Two calibration states, s1 and s2, have equal weight. The team’s rule minimizes expected residual loss; shorter duration breaks equal-loss ties. The following are cardinal comparison inputs.
| Present model T0 | A | B | C |
|---|---|---|---|
| Residual loss in s1 | 6 | 2 | 4 |
| Residual loss in s2 | 8 | 3 | 5 |
| Expected residual loss | 7 | 2.5 | 4.5 |
Completed decision. Retain T0 and: “The research team chooses B now among A, B and C for this experiment. At equal state weights the expected losses are 7, 2.5 and 4.5. We minimize expected residual loss, with duration breaking ties.” B is preferable in either state. The current basis supports this choice; no unresolved inquiry alternative needs a separate account.
A completion form demanding unused probe budget, cost and information/computation fields would add omission accounting to that result. Conditional inquiry content leaves the decision and its basis intact.
Opposed condition. Change the loss model to T1 below. A specified one-day calibration can distinguish the states perfectly, an available technician can perform it, and two days remain. The team accepts that delay for a reduction in expected loss.
| Changed model T1 | A | B | C |
|---|---|---|---|
| Residual loss in s1 | 0 | 3 | 5 |
| Residual loss in s2 | 8 | 3 | 5 |
| Expected residual loss | 4 | 3 | 5 |
Completed first choice. Retain T1 and: “Probe again with the one-day calibration. Choosing B now has expected loss 3; choosing A after s1 or B after s2 has expected loss 1.5. The available day and technician make the probe feasible, and the team accepts the delay for that reduction.” This is a completed C.11 probe-again result. The measurement remains to be performed. An actual s1 result would then select A; s2 would select B.
Transfer requiring a reason. Return to T0, now sent to a colleague considering B for another calibration range. Retain: “B was selected under the two states in T0; distinguishing those states would not alter that choice. This decision establishes no fresh calibration and must be reconsidered for another range.” The explanation changes the colleague’s use: reopen the comparison instead of treating B as generally preferred. It belongs in the same decision result and needs no empty probe block.
