Classic VI: Asking While Knowing the Answer (Testing with Known Facts)
If a ruler asks questions while already possessing the knowledge of the truth, those who are dishonest will be exposed; if a ruler thoroughly understands one specific matter, all hidden treacheries will be transformed. The proof of this lies in Marquis Zhao clutching a fingernail. Therefore, by thoroughly investigating the South Gate, the truth of the three districts was obtained. The Lord of Zhou searching for a curved walking stick caused his ministers to tremble in fear; Bu Pi dispatched a junior attendant to spy; and Ximen Bao meticulously investigated a lost carriage pin.
Note
This excerpt is from “Canon Six: Held‑Knowledge Interrogation” in Han Feizi · Inner Congeries of Sayings I. Han Fei argues rulers should confront ministers with verified facts. Exposing one lie precisely sparks widespread fear of the ruler’s omniscience, restraining all concealed treacherous conduct among officials.
Marquis Zhao Clutching a Fingernail:
Marquis Zhao of Han (韩昭侯) hid a clipped fingernail in his hand and feigned losing it, ordering his attendants to find it urgently. Some attendants cut off their own fingernails to offer as the “lost” one. This is the ultimate ancient lie-detector test: creating a fake demand to see who will fabricate a response to please the boss.
Investigating the South Gate:
Marquis Zhao knew a yellow calf was eating crops outside the South Gate but asked his inspectors what they saw. When they reported vaguely, he ordered a strict census of crop damage and pointed out the South Gate detail when their reports were incomplete. The officials were terrified by his apparent omniscience. This illustrates using a micro-fact to enforce macro-compliance.
The Lord of Zhou’s Curved Stick:
The Lord of Zhou asked his officials to find a curved walking stick. They failed after days of searching. He then had a private servant find it in less than a day. The stark contrast proved the officials’ incompetence or laziness, establishing a lasting psychological deterrent.
Bu Pi’s Spy Mission:
Bu Pi (卜皮), a county magistrate, suspected a censor of corruption. Instead of confronting him directly, he sent a junior attendant to befriend the censor’s favorite concubine to gather intelligence. This shows the use of indirect networks to bypass official information blockades.
Ximen Bao’s Lost Carriage Pin:
Ximen Bao, the famous magistrate of Ye, faked losing a carriage axle pin. When his subordinates failed to find it, he had others search and found it in a local’s home. This allowed him to instantly distinguish between diligent and negligent officials.
Asking While Knowing the Answer / Testing with Known Facts:
This method is essentially a proactive lie-detector test. The ruler uses a known fact as a trap; if the subordinate lies or covers up, they fall into the trap.
Thoroughly understanding one matter transforms all hidden treacheries:
This is the concept of exemplary deterrence. By exposing one specific lie with absolute certainty, the ruler creates a systemic illusion of omniscience. Subordinates assume that if the ruler knows this one small thing, he probably knows everything else, causing them to self-censor.
Cognitive Dissonance in Governance:
As modern management theory notes, this technique forces subordinates into cognitive dissonance. When their fabricated reports clash with the ruler’s undeniable facts, their psychological defenses break down, exposing their true nature.
经六 挟智
挟智而问，则不智者至；深智一物，众隐皆变。其说在昭侯之握一爪也。故必审南门而三乡得。周主索曲杖而群臣惧，卜皮使庶子，西门豹详遗辖。
