Displayed weakness read as concealed strength, so an undefended position deters an attack it could not survive.
In the novel, Zhuge Liang faces a large army with an empty city, opens the gates and sits playing the lute on the wall. The opposing commander, who knows him as cautious, reads the display as a trap and withdraws. The strategy works only against someone who credits you with more prudence than you are showing.
In practice
- A startup publishes its roadmap in full, and a larger rival reads the openness as evidence of something held back.
- A negotiator who lets the other side see an empty diary is believed to have a better offer elsewhere, until they check.
- Possible explanations
- The explanation is inference from reputation: an opponent who believes you are cautious reads an undefended position as evidence of a trap, so the display works only against someone who knows you.
- In its favour
- The logic is sound as a signalling problem, and the episode is among the most studied illustrations of deception in Chinese strategic writing.
- Against it
- The episode comes from a fourteenth-century novel rather than a chronicle, so the case may not have happened, and the stratagem fails badly against an opponent who simply attacks.
- Standing
- The episode comes from a novel rather than a chronicle; whether Zhuge Liang did any such thing is not established.
