A Genuine Smile Is Not Primarily About the Mouth
Särnblad argues that joy is easiest to see in cheek movement rather than lip shape. Genuine joy raises and rounds the cheeks, causing the skin beneath the lower eyelids to bulge into what she calls smile bags; the useful signal is the change from that person's neutral face.
- Lip shape alone does not establish genuine joy
- Joy raises and rounds the cheeks
- The under-eye skin becomes visibly fuller
- The observer should compare the change with the person's baseline
“the smile has nothing to do with the mouth nothing at all”
“when we experience Joy our cheeks pop up they lose gravity”
