The reason why is because your facial expressions can make other people tell if you are not being truthful and not telling the truth. The author states this in paragragh 8 saying " To an expert, faces don't lie: these muscle clues are somtimes used to spot when a "smiling" polaticion or celebrity isn't being truthful."
