The Risks We Dread: A Social Circle Account 

From the summary at Full Text Reports

What makes some risks dreadful? We propose that people are particularly sensitive to threats that could kill the number of people that is similar to the size of a typical human social circle. Although there is some variability in reported sizes of social circles, active contact rarely seems to be maintained with more than about 100 people. The loss of this immediate social group may have had survival consequences in the past and still causes great distress to people today. Therefore we hypothesize that risks that threaten a much larger number of people (e.g., 1000) will not be dreaded more than those that threaten to kill “only” the number of people typical for social circles. We found support for this hypothesis in 9 experiments using different risk scenarios, measurements of fear, and samples from different countries. Fear of risks killing 100 people was higher than fear of risks killing 10 people, but there was no difference in fear of risks killing 100 or 1000 people (Experiments 1–4, 7–9). Also in support of the hypothesis, the median number of deaths that would cause maximum level of fear was 100 (Experiments 5 and 6). These results are not a consequence of lack of differentiation between the numbers 100 and 1000 (Experiments 7 and 8), and are different from the phenomenon of “psychophysical numbing” that occurs in the context of altruistic behavior towards members of other communities rather than in the context of threat to one’s own community (Experiment 9). We discuss several possible explanations of these findings. Our results stress the importance of considering social environments when studying people’s understanding of and reactions to risks.

Private chats become the new suicide hotline on Facebook — VentureBeat

 

 

Author’s comment….

A few years back I was in a Yahoo chat room conversing with someone who suddenly started talking about his suicidal thoughts.
Very quickly I was able to get ahold of a suicide hotline number and pass it on to him. He thanked me and left the room.
To this day I think about him, wondering if he called, and if he is OK……

 

Private chats become the new suicide hotline on Facebook 

From the 15 December 2011 Forbes article

Facebook unveiled a suicide prevention tool to give users a direct link to online counselors, illustrating the social network’s efforts to expand its role in responding to crises.

With the feature, friends can report suspected suicidal behavior by clicking a button next to any piece of content on Facebook. Users select “suicidal content” under the harmful behavior menu, prompting Facebook to email a direct link to the distressed user for a private online chat with a crisis representative from the National Suicide Prevention Lifeline.

The tool provides help to those who may not be comfortable picking up the phone or seeking other direct avenues for assistance.

The concerned friends, whose reporting of the behavior will be anonymous, will also receive a message that the issue is being addressed, according to Facebook, which will offer the tool for users in the U.S. and Canada.

The tool formalizes Facebook’s past assistance to users in times of distress. This summer, a Florida woman reportedly used Facebook to call for help after breaking her leg, and Facebook helped a Tennessee woman without a phone contact police after a robbery, illustrating the growing role social networks play in public safety.

In addition to these anecdotal uses, Facebook has been pursuing official ways the social network can help those in natural disasters and other crises….

The role Facebook played likely prompted the Department of Health and Human Services, or HHS, to explore how social media can help in federal efforts to help prepare and deal with such emergencies.

The HHS is developing a text message service that local authorities can broadcast to inform people during emergencies.

From the 16 November 2011 Medical News Today article

It turns out nice guys can finish first, and David Rand has the evidence to prove it.

Rand, a post-doctoral fellow in Harvard’s Department of Psychology and a Lecturer in Human Evolutionary Biology, is the lead author of a new paper, which found that dynamic, complex social networks encourage their members to be friendlier and more cooperative, with the possible payoff coming in an expanded social sphere, while selfish behavior can lead to an individual being shunned from the group and left – literally on their own.

As described this week in the Proceedings of the National Academy of Sciences (PNAS), the research is among the first such studies to examine social interaction as a fluid, ever-changing process. Previous studies of complex social networks largely used static snapshots of the groups to examine how members were or were not connected. This new approach, Rand said, is the closest scientists have yet come to describing the way the planet’s 6 billion inhabitants interact on a daily basis.

“What we are showing is the importance of the dynamic, flexible nature of real-world social networks,” Rand said. “Social networks are always shifting, and they’re not shifting in random ways. …..

New Study Shows Online Dependency Increasing, Tips on Reducing Online Dependency

From the 26 July 2011 Medical News Today article

If you are reading this right now, you’re online. It is estimated that there were 2.1 billion Internet users worldwide, but what would happen if suddenly we were all unplugged and offline, back to basics if you will?

In a new survey of 1,000 people, 53% said they felt upset when they were denied access to the Internet, and 40% said they felt lonely when they were unable to log on to the World Wide Web. Participants were questioned about their attitudes towards the Internet, and were asked to go without technology for 24 hours. That meant no Facebook, Twitter, emails and text messages.

After the 24 hours were up, some volunteers compared the experience to quitting smoking or drinking, and one even described it as “having my hand chopped off.”

Read the rest of the article, including suggestions on how to reduce your dependency on the Web.
