"Yale psychology professor Marianne LaFrance draws on the latest research—in fields from biology to anthropology to computer science—in an effort to shed some light on the happy face."
O, The Oprah Magazine "LaFrance’s extensive research, clear and sometimes humorous writing, and interdisciplinary approach make this a very fine book for anyone who smiles (or doesn’t)."
Publishers Weekly "LaFrance ... Read moreshows that there is much more to a pair of upturned lips than meets the eye."
Scientific American "A masterly example of social sciences at its best—a look at how researchers do their work, what questions they ask, how answers lead to new questions, and why all of this matters in our everyday lives. . . . LaFrance’s true subject is not simply the smile but its uniquely human double purpose: to convey our feelings—and disguise them."
