words can lie, faces don’t
When people try to hide their emotions, even when they repress them unconsciously, a very quick facial expression occurs, almost invisible for the naked eye. Being able to see these micro-expressions allows us to detect deception and lies, to calm a person or even say the appropriate words in the right moment.
Despite the effort made to hide any sign of emotion that is experienced, it is possible to detect small fragments of expression that can be easily recognized. These small changes can also occur when a certain emotion is beginning.
It is important to note that due to the visual differences of human beings, not all people reach the same level of ability to detect these facial expressions.
This knowledge has numerous applications.
