text: Dr. Paul Eckman, the creator of FACS, is able to detect someones emotions without his new system. If Dr. Eckman could teach people how to detect someone's emotions then it would spread across the world then nobody would need the new system. When Dr. Eckman told us to look in the mirror and do the three steps he provided he was teaching us how to detect if someone is happy. Dr. Eckman created something that could be easily taught to people around the world. If people are able to be taught what FACS could do then therefor you do not need FACS.
