Why is body language seen as more true than what you say?

Here's a question - when a person's body language contradicts their verbal messages which do you attend to? You answered body language right? Why is that? Research has shown that:
- Verbal behaviour is easier to fake,
- Non verbal behaviour is often unconscious and tends to let slip how we really feel about other people,
- When we pick up on someone's body language we tend to interpret it as “getting a feeling from that person” and because we can not isolate the cause, that feeling may be trusted as correct.
