It takes a lot of effort to lie with a straight face, much less a neutral body language and an inconspicuous tone. As such, it isn’t all that difficult to tell when someone is lying most of the time. The trick is to see past the words and pay keener attention to their nonverbal communication.
Are there people who can pass off a lie for a truth even against keen observation? Chances are, yes. Heck, you see well-rehearsed politicans and public speakers do it all the time, especially once they get drilled and trained in acting out earnest body language. They do come few and far between, though, especially when it comes to people in your life. A lot of the time, you’ll be able to catch folks on a fib by simply watching for specific cues.
