Fable
Three shelves of books pulled from a single index card in the archive
The national history office received a question: why did that salt tax reform thirty years ago fail? The new clerk first searched by "salt tax reform" and brought back three volumes of edicts. After reading them, he knew only the outcome, not the cause.
The curator told him to continue tracing clues from the volume. The decree mentioned that "shipping in the southeast was blocked," so he went to the shipping cabinet; in the shipping volume appeared "private port commissions," which led him to the coastal defense case; in the coastal defense case there was a memorial from a local official, mentioning that rising grain prices affected salt prices.
The scribe complained it was like digging a well, one layer after another. The curator said the answer to this kind of question was never in the first shovel of soil. The material found the first time should help you generate a more precise question for the next round.
They also set stop-loss rules. Each round of pursuit had to explain why to continue, and any new volume found had to be able to change the answer; if after three rounds only side branches remained, they stopped and organized. Otherwise the archive would be dragged into a bottomless pit by clues.
The final report linked the imperial edict, shipping, private ports, grain prices, and local memorials into one chain. If only the first round were investigated, the conclusion would stop at 'the court's orders were ineffective'; after progressive investigation, it became clear that multiple factors affected one another.
The new scribe thought this was too slow and wanted to pull out all the cabinets at once. The curator stopped him: moving everything would overwhelm, moving too little would break the thread. The real method is to read one thread end, then follow it to the next cabinet; each time a new scroll is found, judge whether it brings a new clue.
Only after several rounds did the pattern of the salt tax failure surface: blocked shipping pushed up private port commissions, private port commissions changed grain prices, and grain prices in turn made the salt price policy fail. The answer was not opened by the first key; behind each door another key appeared. Complex problems often require reading and chasing as you go, until the clues no longer extend. In the end the new clerk compiled a clue map rather than a pile of unrelated files. The curator said that when pursuing a deep problem, each piece of material found should change the next search; if the direction of search is never rewritten by new evidence, that is just repeatedly rummaging through cabinets.
The scribe understood that some searches aren't about grabbing everything at once, but about reading while asking and asking while searching. Each round of material should open the next, more relevant door, until the question is sufficiently explained—not buried under a pile of paper.
