00:00Scientists have been debating for years how many different facial expressions humans have.
00:05The numbers range from 21 to 250,000.
00:09All this to say, reading someone's body language is not an exact science.
00:13So whether you're trying to understand your partner better or trying to become a more convincing liar,
00:19listen to what experts think you should be noticing when analyzing body language.
00:23In the book Rethinking Body Language, Professor Beattie argues that to read body language, you need to know where to
00:31look.
00:31Facial expressions can be controlled.
00:34So how can you tell when a smile is fake?
00:37A genuine one involves the muscles around the eyes and fades slowly from the face.
00:42A fake masking smile leaves the face abruptly.
00:46So in order to decode a fake smile, you need to focus on what happens immediately after it disappears.
00:52And although it's not breaking news that crossing your arms over your chest tells that you feel defensive
00:57or if you're fiddling with your hair while talking, you feel nervous,
01:01Science Alert reports there's more complexity to reading body language than these static poses.
01:07Gesture and speech can reveal a lot about the true emotions of a person.
01:11The unconscious gesture is often the more reliable indicator of the underlying thought.
01:16So either practice that fake smile on a mirror or find a way to stay true to your emotions.
