I do not mean to get off topic, but I must ask: How can you tell someone is lying from micro expressions?
Often because the micro expressions contradict what is being said. It's not an easy call to make and is rarely just because of micro expressions, it also has to do with language used and knowing the person helps to, also being really logical any flaws in peoples stories really stick out, that others may not read into.
There are seven universal micro expressions: disgust, anger, fear, sadness, happiness, surprise, and contempt and when these do not match up with the story or body language, it is often an indicator of deception.
It can also be used by asking a question that should cause a specific response (if they are being truthful) both with body language and micro expressions, when this doesn't, it can also be an indicator.
But as with anything this is not clear cut, one example may be someone who has had a story told to them that they believe is the truth as they will then display the correct micro expressions / language even though what that are saying is incorrect in reality.
