The Mystery of the European Smile: A Comparison Based on Individual Photographs Provided by Internet Users

摘要

The aim of the study was to analyze cross-cultural differences in preference for smiling among the users of one of the most popular instant messaging sites called Windows Live Messenger in terms of facial expression (smiling vs. non-smiling) on the photographs accompanying their profiles. 2,000 photos from 10 countries were rated by two independent judges. Despite the fact that 20 years have passed since the fall of the Berlin Wall, Internet users from a former Soviet bloc appear to smile less often than those from Western Europe. Also, replicating past research, women irrespective of their nationality smiled more than men.
