How to differentiate between a genuine smile and a non-genuine smile


    How to differentiate between a genuine smile and a non-genuine smile

  • 1 The muscles around the eye don't move

    When a smile is genuine, the muscles around the eyes are engaged, and so a noticeable change happens in those muscles. A fake smile usually doesn't cause that change in those muscles. See also why people touch their nose while speaking.

  • 2 The whole face smiles

    When a smile is genuine, the whole face appears to be smiling. When a smile is fake, the mouth usually smiles on its own, leaving the rest of the face intact.

  • 3 Genuine smiles usually last for some time

    While it's not a rule, genuine smiles usually last for a few seconds on the face even when a person looks away. The more emotionally charged the smile is, the more likely it is to last on the face.

  • 4 The bottom teeth in the mouth don't appear

    When a person fakes a smile, his bottom teeth can usually be seen through his mouth. If a smile is genuine then the bottom teeth might not appear. It's important to note that the appearing of the lower teeth doesn't always indicate that the smile is fake.

  • 5 Lines appear around the eyes when the smile is genuine

    Not only are the eyes involved when a smile is genuine, but also lines around the eyes -called crow's feet- are usually formed.

  • 6 Genuine smiles are late coming

    Some people suggest that genuine smiles don't appear instantly, but they take their time to form. See why people touch their faces while speaking.

  • 7 More facial muscles are involved in genuine smiles

    Generally, a genuine smile triggers more facial muscles than a fake smile.

  • 8 Eyes close in genuine smiles

    When a genuine smile is emotionally intense, the eyes might close a bit. See also why people touch their brows while speaking.
