Never start moving your own lips and teeth before the subordinates do. The longer I keep quiet, the sooner others move their lips and teeth. As they move their lips and teeth, I can thereby understand their real intentions. . . . If the sovereign is not mysterious, the ministers will find opportunity to take and take.
—Han Fei-tzu
Power is in many ways a game of appearances, and when you say less than necessary, you inevitably appear greater and more powerful than you are. Your silence will make other people uncomfortable. Humans are machines of interpretation and explanation; they have to know what you are thinking. When you carefully control what you reveal, they cannot pierce your intentions or your meaning. Your short answers will put them on the defensive, and they will jump in, nervously filling the silence with all kinds of comments that will reveal valuable information about them and their weaknesses. They will leave a meeting with you feeling as if they had been robbed, and they will go home and ponder your every word. This extra attention to your brief comments will only add to your power.
