Facebook Provides Valuable Safety Net for the Bereaved, Study Finds
Neuroscientists have long noted that if certain brain cells are destroyed by, say, a stroke, new circuits may be laid in another location to compensate, essentially rewiring the brain.
One expert in computational social science, wanted to know if social networks responded similarly after the death of a close mutual friend.
In new research published on Monday, Northeastern’s William R. Hobbs found that friends on Facebook did provide new avenues of communication, pointing to a strength of social networks—providing resilience.
Hobbs, who led the study, collaborated with Facebook data scientist Moira Burke. The researchers found that close friends of the deceased immediately increased their interactions with one another by 30 percent, peaking in volume.
The interactions faded a bit in the following months and ultimately stabilized at the same volume of interaction as before, but this insight into how social networks adapt to significant losses could lead to new ways to help people with the grieving process.
“Most people don’t have very many friends, so when we lose one, that leaves a hole in our networks as well as in our lives,” says Hobbs, a Professor of Political Science and Computer and Information Science.
He then wondered: Would a social network unravel with a central member gone? If it recovered, how might it heal?
“We expected to see a spike in interactions among close friends immediately after the loss, corresponding with the acute grieving period,” says Hobbs. “What surprised us was that the stronger ties continued for years. People made up for the loss of interacting with the friend who had died by increasing interactions with one another.”
Hobbs came to the study from a crisis of his own. After college, he lived and worked in China studying local governments. But when he entered graduate school at the University of California, San Diego, his father was dying. “So I switched to American politics, then to studying chronic illnesses, and then moving into the effect of deaths on others,” he says.
That switch led to this first large-scale investigation of recovery and resilience after a death in social networks.
