Check out this study from James Fowler and Nicholas Christakis, called Dynamic spread of happiness in a large social network: longitudinal analysis over 20 years in the Framingham Heart Study.
Here are a couple of quotes from the abstract to whet your interest:
"the relationship between people’s happiness extends up to three degrees of separation (for example, to the friends of one’s friends’ friends). People who are surrounded by many happy people and those who are central in the network are more likely to become happy in the future. Longitudinal statistical models suggest that clusters of happiness result from the spread of happiness and not just a tendency for people to associate with similar individuals."
"People’s happiness depends on the happiness of others with whom they are connected."
Makes you think about your network and with whom you spend time. It should also make us all think about how we are impacting others - positively and negatively.
I talk to a lot of folks from many organizations. The complaint I often hear is that people are dissatisfied with their jobs because the place/department/team is a ball of negativity and no fun to work within.
As organizational leaders, how ought the results of this longitudinal study (which likely backs up what we believed to be true) change how we manage, select, promote, measure, and relate? How ought these results change our talent management systems and practices?
