Genuine (Duchenne) Smile Signs:
- Crow's feet: Wrinkles appear at the outer corners of the eyes
- Narrowed eyes: The eyes squint slightly, with raised lower eyelids
- Raised cheeks: Cheeks push up toward the eyes
- Eye-mouth connection: The whole face participates in the expression
Fake (Social) Smile Signs:
- Eyes stay neutral: No crow's feet, eyes remain wide open
- Smooth eye area: Skin around eyes stays flat and unwrinkled
- Mouth-only smile: Only the mouth moves while eyes stay disconnected
- Symmetry issues: Sometimes appears more asymmetric or held too long
Why this matters:
- Reading genuine vs fake smiles is a core social cognition skill
- Helps detect deception, build trust, and improve relationships
- Most people score 50-70% on smile detection tests
- This skill can be improved with practice and feedback
