CORE DEFINITION

Do not act personally; use the power of a third party (such as public opinion, regulators, or other competitors) to attack the enemy, thereby avoiding taking risks yourself or exposing your strength through counterattack.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Leverage ecosystem forces. If you want to attack a competitor's violations, do not issue your own press release (which can easily be seen as malicious competition), but submit evidence to regulatory agencies or consumer associations (borrowing a knife) to use public power to solve the problem.

anchor

Anchor fast decisions

One of the Thirty-Six Stratagems: do not act directly, but borrow the power of a third party (public opinion, regulators, contradictions among opponents) to strike the target, making yourself avoid suspicion, save effort, and not expose your strength. The essence is to "leverage others' motives" — find a third party that conflicts with the target, provide incentives/evidence to make them act.
