If tripping in public or mistaking an overweight woman for a mother-to-be leaves you red-faced, don’t feel bad. A new study from the University of California, Berkeley, suggests that people who are easily embarrassed are also more trustworthy, and more generous.

In short, embarrassment can be a good thing.

“Embarrassment is one emotional signature of a person to whom you can entrust valuable resources. It’s part of the social glue that fosters trust and cooperation in everyday life,” said UC Berkeley social psychologist Robb Willer, a coauthor of the study published in this month’s online issue of the Journal of Personality and Social Psychology.
