Article 2: The Contagion of Happiness
A trained hypnotist can, if permitted by the subject, make a direct intervention into another's mind... and mood. But minds touch hypnotically, naively, even without mastery of the hypnotic arts.
A major study by James H Fowler, associate professor at UC San Diego and Nicholas A Christakis, professor Department of Health Care POlicy, Harvard Medical School and Department of Sociology, Harvard University, published in the December 4, 2008 issue of BMJ, entitled Dynamic spread of happiness in a large social network: longitudinal analysis over 20 years in the Framingham Heart Study, teaches that a person's social network has a profound effect on his or her happiness:
While there are many determinants of happiness, whether an individual is happy also depends on whether others in the individual’s social network are happy. Happy people tend to be located in the centre of their local social networks and in large clusters of other happy people. The happiness of an individual is associated with the happiness of people up to three degrees removed in the social network. Happiness, in other words, is not merely a function of individual experience or individual choice but is also a property of groups of people. Indeed, changes in individual happiness can ripple through social networks and generate large scale structure in the network, giving rise to clusters of happy and unhappy individuals. These results are even more remarkable considering that happiness requires close physical proximity to spread and that the effect decays over time.***
Our data do not allow us to identify the actual causal mechanisms of the spread of happiness, but various mechanisms are possible. Happy people might share their good fortune (for example, by being pragmatically helpful or financially generous to others), or change their behaviour towards others (for example, by being nicer or less hostile), or merely exude an emotion that is genuinely contagious (albeit over a longer time frame than previous psychological work has indicated).
