In the middle of a phone call four years ago, Paula Niedenthal began to wonder what it really means to smile. The call came from a Russian reporter, who was interviewing Dr. Niedenthal about her research on facial expressions.
“At the end he said, ‘So you are American?’ ” Dr. Niedenthal recalled.
Indeed, she is, although she was then living in France, where she had taken a post at Blaise Pascal University.
“So you know,” the Russian reporter informed her, “that American smiles are all false, and French smiles are all true.”
