David Rand: The more friends you have that are content with their lives, the more likely you are to become content. And the more friends you have that are discontent, the more likely you are to become discontent.
David Rand of Harvard is one of the study’s authors. He said this study was designed to understand how changes in long-term emotional states – meaning, whether you consider yourself a happy or sad person overall – are affected by the people you know. 外语￥教育网www.for68.com
David Rand: We found that sadness is twice as infectious as happiness.
Rand and his co-authors compared emotional states of groups of friends, families, and coworkers to models of how infectious diseases – like the flu – spread. Then they looked at the probability that a person would become happy or become sad, based on the number of happy or sad people around them.
David Rand: One aspect that’s new is that we showed in a formal sense that these long-term emotional states really are contagious. Which is interesting, and it’s important for trying to understand why people feel the way they do about their life.
