> The key to faking a real smile is in wrinkling the eyes. The wrinkling is not a very reliable indicator of fake smiles [1]. A real smile does indeed involve muscles around the eyes, but wrinkling could be caused by the cheek muscles pushing upward too. Some more indicators of a real smile are, IIRC
- curling corners of the mouth
- corners of the eye pushing inward
- short duration
- it starts and ends smoothly
- symmetry [1] Source: Having recently read "Telling Lies" by Paul Ekman (and that was a HN recommendation too) |
