ARISTOTLE RECKONED the face was a window onto a person’s mind. Cicero agreed. Two millennia on, facial expressions are still commonly thought to be a universally valid way to gauge other people’s feelings, irrespective of age, sex and culture. A raised eyebrow suggests confusion. A smile denotes happiness. A frown indicates sadness.Or do they? An analysis of hundreds of research papers that examined the relationship between facial expressions and underlying emotions has uncovered a surprising conclusion: there is no good scientific evidence to suggest that there are such things as recognisable facial expressions for basic emotions which are universal across cultures. Just because a person is not smiling, the researchers found, does not mean that person is unhappy.
