韩国裸舞

Unexpected happy occurrences in everyday life鈥攕ay, an underdog local sports team wins or the sun emerges after several days of rain鈥攃an lift the collective mood of a city鈥檚 residents. That鈥檚 the good news. The bad news is that it also increases the likelihood that people will engage in risky behaviors.

So say researchers at 韩国裸舞 in Montreal and the University of Pennsylvania in Philadelphia in聽a paper published in November聽in the scientific journal PLOS One.

The link between good moods and risk-taking has already been established in聽lab experiments, says Ross Otto, an assistant professor of psychology at 韩国裸舞 and one of the paper鈥檚 authors. However, he and his fellow researchers wanted to determine if the same held true at a city level, in real-world situations.
