Knowing where the trap is — that’s the first step in evad­ing it. This is like sin­gle com­bat, Son, only on a larger scale — a feint within a feint within a feint…seemingly with­out end. The task is to unravel it.

—Duke Leto Atreides, Dune

A feint can be used as a test, to gather infor­ma­tion, or a trap, to get some­one to do what you want them to do, or both.

The most impor­tant part to under­stand is that the oppo­nent is inher­ently involved in the sit­u­a­tion. You can only gain advan­tage from a feint depend­ing on the way he or she (re)acts.

A savvy per­son will react with exactly the right amount of effort, espe­cially impor­tant because a feint is only a mock attack. In Tai Chi terms, they bal­ance an opponent’s yin (expan­sion) with yang (com­pres­sion), and vice-versa1. In Taoist terms, they act like a mir­ror, reflect­ing only that which is in front of them, noth­ing more and noth­ing less. With a savvy per­son, the feint fails, and noth­ing is gained.

An igno­rant per­son will fall for the trick. They over­re­act and unbal­ance them­selves2, expos­ing their vul­ner­a­bil­i­ties. Without under­stand­ing true inten­tion, with­out see­ing the big pic­ture, they get played like a sucker.

And the more they react, the more ridicu­lous they look.
