Paul Ekman, the professor of psychology who has become the world's most famous face reader, is much in demand these days. The Dalai Lama and Dr. Ekman, who have met twice, found such synergy in their understanding of human emotions that the Dalai Lama gave Dr. Ekman for help learning to read subtle emotional cues from the faces, voices and body language of potential assassins, terrorists and questionable visa applicants. Around the world, more than people -- including neurologists, psychiatrists and psychologists -- have learned Dr. Ekman's research tool called FACS, or Facial Action Coding System, for deciphering which of the 43 muscles in the face are working at any given moment, even when an emotion is so fleeting that the person experiencing it may not be conscious of it.

But an author of the original report—published nearly three decades ago—says that the new analysis has shortcomings, and may not represent a direct replication of his work. The paper has been cited more than a thousand times, and has been followed by other research into facial feedback. In , for example, researchers reported that injections of Botox, which affects the muscles of facial expression, dampen emotional responses. Overall, the experiments found no difference in the way people with pen-induced smiles or frowns rated the cartoons. And 16 of the experiments tested enough people for there to be statistical confidence that even if the studies had been repeated many more times, the researchers would have found the same null result, says Eric-Jan Wagenmakers, a psychologist at the University of Amsterdam who led the analysis. But Strack disagrees.
