Remember:

Knowing that someone is lying doesn’t tell you why they’re lying.  Motive trumps action (think of murder as self-defense).

This leads you down a rabbit hole, sometimes to self-exclusion because when you know someone is lying to you, its hard to let it go.

Don’t believe me?  Take it from Paul Ekman; he developed FACS, or the Facial Action Coding System.

“In general we have a choice about which stance we take in life,” says Paul Ekman. “If we take a suspicious stance life is not going to be too pleasant, but we won’t get misled very often. If we take a trusting stance, life is going to be a lot more pleasant but sometimes we are going to be taken in. As a parent or a friend, you’re much better off being trusting rather than looking for lies all the time.”
