“By discovering the enemy's dispositions and remaining invisible ourselves, we can keep our forces concentrated, while the enemy's must be divided.”
Visibility lets you concentrate while forcing the opponent to scatter; information asymmetry is the mechanism.
Chapter 6 formalizes the information asymmetry its tactics require: by discovering the enemy’s dispositions and remaining invisible ourselves, we keep our forces concentrated while the enemy’s must be divided. The mechanism is almost hydraulic — sight lets one side pool its strength; blindness forces the other to sprinkle its defense. Intelligence is not a report; it is a concentration device.
An e-commerce challenger instruments everything public about the incumbent — pricing feeds, hiring posts, warehouse permits — while revealing nothing of its own next category. The incumbent, seeing only a quiet boutique, defends nothing; the challenger sees exactly where the thin spots are. On launch day the entire assault lands on the one subcategory the incumbent had deprioritized that quarter — concentrated against a fraction.
The asymmetry must be honest to hold — knowing them better does not mean assuming them stupider, and the visibility gap closes the moment you act. Sun Tzu’s version is disciplined: continuous discovery on one side, continuous concealment on the other, both maintained. A one-time intelligence coup spent loudly buys one win and a permanent lesson for the enemy.
