What we say represents just a small portion of what we communicate. Humans leak information about what’s going on in their heads through a number of channels, usually without any awareness that they’re doing it. We share information through our tone of voice, body language, microexpressions, and external identity cues.
With practice, it’s possible to learn how to read these nonverbal indicators. When you “listen” to everything a person is communicating, and not just what the words they’re speaking, you get a much more complete picture of what they’re saying. And when you understand what’s going on in someone’s head, you can choose your words more effectively.
