When what a character doesn't say reveals more about them than any monologue could.
Silence as characterization uses the deliberate absence of dialogue to define who a character is. A character who doesn't answer a direct question is telling you something. A long pause before responding communicates internal conflict. A character who never discusses their past is defined by that avoidance. Games can implement this mechanically: dialogue options that include silence as a choice, characters who shut down when certain topics arise, or moments where the expected dialogue simply doesn't happen. This technique requires confidence from the writers -- trusting the player to read the absence rather than spelling everything out. It works because players are naturally curious about gaps, and silence creates a void that imagination fills.
Example
In Shadow of the Colossus, Wander barely speaks, and his silence during increasingly questionable actions becomes a characterization of obsessive single-mindedness. In Red Dead Redemption 2, Arthur sometimes doesn't respond to provocations, and those moments of swallowed words tell you more about his restraint and inner conflict than his actual dialogue does.
Why it matters
Silence as characterization treats players as perceptive readers of human behavior. It creates depth through restraint and generates speculation that makes characters feel more real than exposition ever could. The most memorable characters in gaming are often defined as much by what they withhold as what they share.
