Tests conducted at the university of Pennsylvania's Psychological Laboratory showed that anger is one of the most difficult emotion to detect from facial expression. Professor Dallas E. Buzby confronted 716 students with pictures of extremely angry persons and asked them to identify the emotion from facial expression. Only 2 percent made correct judgments. Anger was most frequently judged as "pleased." And a typical reaction of a student with the picture of a man who was hopping mad was to classify his expression as either "bewildered", "quizzical", or simply "amazed". Other students showed that it is extremely difficult to tell whether a man is angry or not just by looking at his face. The investigators found further that women are better at detecting anger from facial expression than men are. Paradoxically, they found that psychological training does not sharpen one's ability to judge a man's emotions by his expressions but appears actually to hinder it. For in the university tests, the more courses the subjects had taken in psychology, the poorer judgment scores he turned in.
