Some psychologists call these defensive lies , because the goal, in the end, is to preserve our relationship with the other person. He lies for fear to be deprived of the other's love. People who tend to say everything they think are very sure of themselves and are not afraid to lose that love.
British scientists have developed a system that lets you know if someone is telling the truth thanks to a sophisticatedfacial scanner . And it is that a simple gesture of our physiognomy reveals everything we want or not say. The face shows a lot of emotions in the form of changes in the expression or the Blood flow , and it is something that escapes our control when we are lying.
