This image is an example of Donald Trump's most common variation of a Social Smile. It is NOT a sincere one. Mr. Trump displays a sincere smile of joy-happiness (Duchenne Smile) on exceedingly rare occasions. To thin-slice this particular expression (which Trump projects in place of a smile) a bit further - the primary emotion being felt (and thus transmitted) here is Disgust.
Some people may say, "That's just the way Trump smiles." Wrong. This is a ruse - and anything but sincere. It's also important to note that there are many - and more palatable types of social smiles.
What is your "go-to" social smile? Can you smile sincerely "on-demand"? Are you able to readily differentiate sincere smiles from the many variants of insincere smiles?
