Real Smiles

Real smiles are believed to be Duchenne smiles because 80% of people aren't able to control the muscles around their eyes naturally, meaning they're more genuine. People are more trusted when they show a real smile because they're showing genuine emotion.

Testing the 80%

Krumhuber and manstead (2009) researched if the 80% idea was true When photos were taken 83% of the fake smiles were believed to be true. But in video they found harder to show a fake smile because it was easier to read the other contributing factors (i.e. impatience, how long it was held, other emotions showing through, etc.).
