 ビリー・ジョエルは1973年のヒット曲「ピアノ・マン」で、寂しさlonelinessを紛らすには1人で飲まない方がよいと歌っている。
 しかし、その逆も起こりうるとの新たな研究が発表された。寂しさlonelinessは文字通り、うつや自殺、アル中、薬物中毒などの問題と関連しているが、悪い風邪をひいたように伝染するという。シカゴ大の認知社会神経科学センター長John Cacioppoによれば、寂しさは、以前考えられてきたよりも重大であり、常に孤立isolationの結果と誤認されてきたが、寂しさがさらに孤立に追い詰めるという。
 Framingham Heart Studyのデータから数千人の人々について研究した。どの程度自分が寂しいだと感じた人が社会生活の中でどう影響を及ぼすかを見た。すると、寂しさlonelinessを共有してしまう傾向にあり、その集団が悪い傾向へと向かってしまう可能性がでてくる。
 ネガティブな関係性は累積するだけでなく伝染し、最終的に社会の中のポジションに深い影響を及ぼす可能性がある。(ABC)

 シカゴ大、カリフォルニア大サンディエゴ校、ハーバード大による新たな研究によれば、集団の1人が寂しいと感じ始めるとネガティブな感情が他の人にも広がり寂しいという感情が感じる危険が増してしまうという。
 5,100人の人々とその関係者を10年間にわたり週に何日寂しさの感情feelings of lonelinessを感じるかをフォローしたところ、寂しさの感情は伝染し社会的関係をとおして伝わってゆくとわかった。
 平均的な人で年に平均約48日寂しさを経験するが、寂しい友人を持つと年に17日寂しい日が増加する。友人が1人増えると5%、2.5日寂しい日が減る。
 感情は個人的な経験だが表出され、他の人がそれを読みとりコピーし内在化する。個人の寂しさが社会ネットワークを不安定にするカスケードを形成する。(NYT)

Is Loneliness Contagious?
Your Lonely Feelings Can Drag Others Into a Cycle of Solitude, Researchers Say

画像Did singer Billy Joel have it right in his 1973 hit "Piano Man," when he said that sharing the drink we call loneliness is better than drinking alone?

One new piece of research suggests that the opposite, in fact, may be true.

Adding to what we already suspect about loneliness -- namely, that it is linked to such problems as depression, suicide, alcoholism, drug abuse and other health issues -- researchers now suspect that loneliness, like a bad cold, can spread.

"We have been looking at this topic for well over a decade," said John Cacioppo, director of the University of Chicago's Center for Cognitive and Social Neuroscience and one of the study's authors. "Loneliness is a lot more serious in terms of consequences than people have thought."

He said another misperception is that loneliness is always the result of isolation; in fact, it may be the other way around.

"Loneliness begets you becoming more isolated," Cacioppo said.

Cacioppo was part of a team of researchers from the University of Chicago, the University of California San Diego and Harvard University who looked at the phenomenon. The researchers referred to data gathered from the mammoth Framingham Heart Study, which looked at thousands of people with the original aim of teasing apart the factors involved in heart disease.

But in this case, the team took a different angle on the data -- they wanted to find out how those who frequently reported themselves to be lonely affected those within their social circles.

What they discovered was that those who are lonely tend to share their loneliness with others. Worse, these groups of lonely people can eventually slide to the very edge of the social networks of which they are a part.

The findings were published in the December issue of the Journal of Personality and Social Psychology.

The current research is not the first look Cacioppo and his colleagues have taken at loneliness. A couple of years ago, they published research suggesting that lonely people have, on the whole, more negative social interactions with others than those who are not lonely. So these lonely people, Cacioppo suggests, will be more likely to interpret their social interactions pessimistically.

Loneliness is Actually a Bad Cycle

"If I'm treating you badly, you can tell me to go take a hike," he said. "After time, as this happens more and more, I will be moved to the edge of the social network."

But negative interactions, Cacioppo said, can be contagious as well as cumulative -- and ultimately they can have profound effects on our position in society. The principle behind this contagious aspect of certain behaviors is known as the induction hypothesis. And Cacioppo said that judging from the results of the research; it applies to loneliness as well.

"When people feel lonely, they tend to be shyer, more anxious, more hostile, more socially awkward and lower in self-esteem," he said. "That, in turn, induces other individuals to act in negative ways. ... Emotional contagion could therefore contribute to the spread of loneliness to those with whom they interact."

Chris Segrin, head of the communication department at the University of Arizona, said these circles of friends on the periphery of social networks may also attract each other in a negative feedback loop of loneliness.

"You might think back to when you were in middle school and there might have been a group of social outcasts who hung out," Segrin said. "They're not brought together for some sort of affinity of each other; they're brought together because they're forced out by others."

In that same way, Segrin said this new study shows lonely people tend to drift together in adulthood, too. However, rather than provide solace, Segrin said loneliness may beget loneliness.

"It's called emotional contingent, where I catch your emotional state," Segrin said. "If I'm hanging out with you and you're bringing me down, maybe what I need to do is think about a new circle of friends."

Segrin admitted that it's easier said than done, but in light of the new study he thinks it's only more evidence that lonely people need to take a chance with new faces.

"The lonely people might be trapped in this state of loneliness in part because of their social situation," Segrin said. "It's a matter of finding the wherewithal to take chances with people."

Mark Leary, a member of the American Psychological Association, agreed that loneliness may beget loneliness, but said he doesn't think that lonely people are aware of the slippery slope.

Falling into Loneliness: Accident or Not?

"I don't think it's conscious at all. I don't think people say, 'I'm lonely, people don't accept me, to the heck with it all,'" said Leary, a professor of psychology at Duke University in Durham, N.C.

"What's more true is that when people become lonely, they become somewhat more standoffish and distant," he said.

According to Leary, laboratory studies have clearly shown that lonely people have more problems making conversation. They are often self-absorbed, speak only about themselves or limit their conversation to a narrow range of topics only they find interesting.

"They just don't engage other people as much, they don't inquire other people, they don't follow up on what people have said," Leary said. "Not only is loneliness contagious it's also self perpetuating."

In turn, the people in a conversation with a lonely person start to feel cold and turned off.

"I always hate to use that word contagious, but in principal, yeah it can spread," Leary said.

So if loneliness does indeed spread, what can we do to keep it at bay?

Cacioppo said the answer to this may lie in changing the way we think about loneliness; specifically, he said we should view loneliness as a biological signal akin to hunger and thirst.

"We rely on others to survive and prosper," Cacioppo said. "Loneliness infects you in a way to make you want to connect with others, but also to become socially very wary."

Why Loneliness Can Be Contagious
By TARA PARKER-POPE

When one person in a group begins to feel lonely, the negative emotion can spread to others, increasing everybody’s risk for feelings of loneliness, a new study shows.

In a 10-year study of 5,100 people and their social contacts, researchers tracked feelings of loneliness over time by asking participants how many days a week they felt lonely. What they discovered was that loneliness could be contagious and followed a distinct path as it spread through social networks.

Over time, each additional day of loneliness per week that people experience leads to a little more than one extra day of loneliness per month among those in their social network, according to the article, “Alone in the Crowd: The Structure and Spread of Loneliness in a Large Social Network,” published in the December issue of The Journal of Personality and Social Psychology. The study was conducted by researchers at the University of Chicago; the University of California, San Diego; and Harvard University.

The average person experiences loneliness about 48 days a year, but having a lonely friend can add 17 days of loneliness annually. By comparison, every additional friend can decrease loneliness by about 5 percent, which translates to about two and a half fewer lonely days a year, the study showed.

The idea that loneliness can be contagious is counterintuitive because we tend to believe that, by definition, lonely people keep to themselves. But the study focused on subjective feelings of loneliness, rather than people who were already socially isolated. The research showed that when feelings of loneliness began to emerge, those feelings were transmitted to others before the person began to sever ties and move away from a social network.

“People can feel lonely even when they’re surrounded by other people,” said Dr. Nicholas A. Christakis, a physician and social scientist at Harvard Medical School and co-author of the book “Connected: The Surprising Power of Our Social Networks and How They Shape Our Lives.” “The traditional perspective on human emotion is that emotions are an individual experience. But we don’t just have these emotions, we show them. Other people can read them, copy them and internalize them.”

Dr. Christakis said that much like pulling a single thread could unravel a sweater, a lonely person could destabilize an entire social network, spreading loneliness to others before moving to the periphery of the group.

“If you’re lonely, you transmit loneliness, and then you cut the tie or the other person cuts the tie,” he said. “But now that person has been affected, and they proceed to behave the same way. There is this cascade of loneliness that causes a disintegration of the social network.”

The lesson, Dr. Christakis said, is that it is in everyone’s self-interest to pay attention to those on the fringe of a group.

“When we pay attention to the experiences of those at the periphery, when we make an effort to prevent this sad experience of loneliness, then we can stabilize the whole social network by preventing this kind of unraveling,” he said. “We all benefit when we attend to the needs of those at the margins.”
