- Read about the 'Pan Am smile'. Then look at the photos again. Can you find the fake smiles more easily?
The 'Pan Am smile' is named after the flight attendants with this old American airline. They were famous for their friendly customer service and for always smiling at the passengers. Everyone knew that these smiles weren't genuine but they were an expression of friendliness and had a positive effect on the passengers.
We all use Pan Am smiles because there are many situations where showing unhappiness would be rude. Smiling has the important social function of keeping people happy.
But how can you tell the difference between a genuine smile and a fake smile? In the nineteenth century, French scientist Guillaume Duchenne noticed that we use two sets of facial muscles to smile: around the mouth and eyes. Pan Am smiles only use the mouth, so the secret is to look at the eyes.
