...article was a collaborative effort with Fowler as well as University of Chicago professor John T. Cacioppo that was published Monday in the December issue of The Journal of Personality and Social Psychology. Christakis, Fowler, and Cacioppo used a decade’s worth of data collected by the Framingham Heart Study, which began in 1971 and asked its subjects about their emotional state at regular intervals...
...showing that emotional states and behaviors - including happiness, obesity and quitting smoking - can propagate like a wave throughout a network of people. To examine whether the contagion effect existed with loneliness, the researchers used the same data set that Christakis and Fowler had mined for their earlier studies - the Framingham Heart Study, an ongoing trial originally begun in 1948 to identify risk factors for cardiovascular disease. Thanks to the meticulous way the trial was initially set up, with investigators noting the close family members and friends of each participant to ensure follow-up over the years, Cacioppo, Christakis and Fowler...
Cacioppo and his team focused on the children of the original Framingham cohort, which included more than 5,200 middle-aged men and women. Starting in 1983, more than 4,500 volunteers were asked to fill out three questionnaires, spaced two years apart, about how many days in the previous week they had felt lonely.

Steve Jones, an evolutionary biologist at University College London who has previously held that human evolution was nearing its end, says the Framingham study is indeed an important example of how natural selection still operates through inherited differences in reproductive ability. But Jones argues that variation in female fertility - as measured in the Framingham study - is a much less important factor in human evolution than differences in male fertility. Sperm hold a much higher chance of carrying an error or mutation than an egg, especially among older men. "While it used to be that men had many children in older...
