Darwin discussed that for humans, there are few muscles that are impossible to activate voluntarily, meaning that they are hard to fake intentionally. A study of these micro-expressions can help people in detecting lies and identifying the truthful message behind someone’s words.
4 facial expressions that show a person is lying
Many people claim that they can tell if someone is lying by listening to their “guts” and experts think that “gut reactions” are uncanny accurate judgments based on nonverbal cues we can see.
Our bodies don’t often listen to our words and it’s possible to tell if someone is lying by studying their noticeable asymmetry. For instance, when someone smiles to express their joy or happiness but they are sad, their eyes can tell the opposite. If the eyes look like they are about to cry despite a wide smile, then that person is definitely lying.
