Fable
Before construction of the new bridge began, the city first counted who would be rerouted
Songshan County was preparing to deploy a medicine cart that could choose its own route based on road signs, delivering medicine from the clinic to each village. At first, the county magistrate only asked whether the cart would overturn and whether the horse was fast enough, and the craftsman confidently said it had run ten test trips steadily.
On the third day of the trial run, the medicine cart avoided the muddy road and bypassed the poorest riverside village; when it encountered an out-of-town license plate, it mistook it for a temporary vendor and refused to approach; when delivering medicine to an elderly person living alone, it treated no answer at the door as delivered. The cart was not broken, but harm had already occurred.
The county magistrate first thought of adding a few more road signs—where you may not detour, where you must stop. But the more new signs he wrote, the more people were still missed: villages where the signs could not be seen at night, courtyards with no doorbell, elderly people who could not write an appeal.
The secretary then changed the assessment book into a living book. For each route, first list the people who might be affected, and state what consequences misdelivery, missed delivery and late delivery would each bring; then define manual takeover, appeals, review and suspension conditions. The medicine cart also had to report monthly which villages were bypassed and which people repeatedly appealed.
The county magistrate's first reaction was to have the medicine cart run a few more laps. The craftsman did as told, choosing wide roads, sunny days and villages with people to receive them, and the results still looked good. The muddy road to Hetan Village, the out-of-town license plate, and the silence of the elderly person living alone never entered the trial-run log.
A village doctor reminded him: where the medicine cart passes is only the surface; more important is to ask who will benefit from it, who will be missed because of it, what happens if a packet of medicine is delivered to the wrong place, and who can detect it and stop it. The county office therefore asked the village chief, elders, pharmacies and cart drivers to list the risks together, then set thresholds for appeals, manual delivery and shutdown. Before construction of a new bridge begins, the water conditions must be examined; before a new medicine cart takes to the road, it must first be seen who it might run over.
After the medicine cart was officially on the road, the county office still asked each village to report missed and mistaken deliveries once a month. The assessment ledger was not a paper written for superiors at the start of work, but a way to keep new tools accountable in real populations over time.
Later, the medicine cart still took to the road, but the county no longer asked only whether it was accurate or fast. Before a new instrument enters public affairs, it must first be examined for whom it pushes risk onto, who can call a stop when it errs, and whether those harmed can be seen.
