The principle that meaning lies in change from a normal state rather than in fixed signs.

Example

A calm person who suddenly stills and quietens has just told you something important. It is the departure from their usual manner, not the stillness itself, that carries the message.

How to Read It

Learn the baseline, then read the deviations from it as the true signals. What matters is how a person differs from their own normal manner, not how they compare with anyone else.

A Word of Caution

Without a baseline almost any reading is a guess, so observe before you judge. You cannot know what a change means until you know what the person is like unchanged.
