Emotional quiet riot

The NY Times reports:

How happy you are may depend on how happy your friends’ friends’ friends are, even if you don’t know them at all.

And a cheery next-door neighbor has more effect on your happiness than your spouse’s mood.

So says a new study that followed a large group of people for 20 years — happiness is more contagious than previously thought. . . .

In fact, said his co-author, James H. Fowler, an associate professor of political science at University of California, San Diego, their research found that “if your friend’s friend’s friend becomes happy, that has a bigger impact on you being happy than putting an extra $5,000 in your pocket.”

The researchers analyzed information on the happiness of 4,739 people and their connections with several thousand others — spouses, relatives, close friends, neighbors and co-workers — from 1983 to 2003.
