Psychology Alone in the crowd

The Economist:

ON THE surface, Framingham, Massachusetts looks like any other American town. Unbeknown to most who pass through this serene place, however, it is a gold mine for medical research. Since 1948 three generations of residents in Framingham have participated in regular medical examinations originally intended to study the spread of heart disease. In the years since, researchers have also used Framingham to track obesity, smoking and even happiness over long periods of time. Now a new study that uses Framingham to analyse loneliness has found that it spreads very much like a communicable disease.

Feeling lonely is more than just unpleasant for those who yearn to be surrounded by warm relationships--it is a health hazard. Numerous studies show that loneliness reduces fruit-fly lifespans, increases the chances of mice developing diabetes, and causes a host of adverse effects in people, including cardiovascular disease, obesity and weakening of the immune system. Simply being surrounded by others is no cure. In people, the mere perception of being isolated is more than enough to create the bad health effects. However, in spite of its significant impact, precious little is known about how loneliness moves through communities.
