The next time your face turns red after tripping  over your own feet in public, don't try to hide it--a new study finds that showing your embarrassment actually makes other people view you as more reliable. Researchers at the University of California have carried out the study and found that embarrassment is a good signature of a person to whom you can entrust valuable resources. Not only are the findings useful for people seeking cooperative and reliable team members and business partners, but they also make for helpful dating advice."Moderate  levels of embarrassment are signs of virtue. Our data suggests embarrassment is a good thing, not something you should fight."said Matthew Feinberg, who led the study. While the most typical gesture of embarrassment is a downward gaze to one side while partly covering the face, a person who feels shame, as distinguished  from embarrassment, will typically cover the whole face, Feinberg said. The results were got from a series of experiments. In the first experiment, 60 college students were videotaped describing embarrassing moments, such as making incorrect assumptions  based on appearances. The college students also participated in the "Dictator Game" which is used in economics research to measure altruism . For example, each was given 10 raffle tickets  and asked to keep a share of the tickets and give the reminder  to a partner. The findings, published in the Journal of Personality and Social Psychology, showed that those who showed greater levels of embarrassment tended to give away more of their raffle tickets, indicating(=showing) greater generosity.
