Facial expressions may be an unreliable way to read emotions

We use our faces to communicate, but our facial expressions may not always come across the way we think they do. And we may be just as wrong when reading the faces of others, a study says.

“Many people think they know what other people’s faces should look like when they are happy, sad, angry or afraid,” said Nicola Binetti, the Marie Skłodowska-Curie Fellow at the International School for Advanced Studies in Trieste, Italy, and a co-author of the study. “We found this is not always the case.”
