...research from experts in neuroscience and social science may give us a clue as to why. Although we tend to think of it as a self-contained emotional state - a condition that affects people individually, either by circumstance or by dint of an antisocial personality - researchers now say that loneliness is more far-reaching than that. John Cacioppo, a psychologist at the University of Chicago, believes it is a social phenomenon that exists within a society and can spread through it, from person to person, like a disease. And while everyone feels lonely once in a while, for some...
...volunteers were asked to fill out three questionnaires, spaced two years apart, about how many days in the previous week they had felt lonely. Because most of the participants' friends and family members were also part of the Framingham study, the scientists could track, over time, whether one person's report of loneliness had any impact on the feelings of isolation in other members in his or her social network. Researchers were thus able to rule out the possibility that lonely people simply congregated with other lonely people, or that a shared environmental event, such as a fatal fire...
...results were illuminating: If one person reported feeling lonely at one evaluation, his closest connections (either family or close friends) were 52% more likely to also report feeling lonely two years later. The effect was strongest among those in close relationships, waning as the connections became more distant, but remained significant up to three degrees of separation - in other words, one lonely person could influence whether his friend's friend's friend felt lonely. "Loneliness has been conceived in the past as depression, introversion, shyness or poor social skills," says Cacioppo. "Those turn out not to be right. Research...
...other words, loneliness is not so much a symptom of being companionless as it is a driving force behind social isolation. Rather than simply reflecting the emotional state of one person, Cacioppo says, loneliness is more like an indicator of the social health of our species on the whole - a temperature reading, if you will, of how well- or not so well-integrated we are as a population...
...third person involved, Rudy Guede, left a mountain of physical evidence including fingerprints, footprints and DNA on Kercher's body, but the material evidence against Knox and boyfriend Raffaele Sollecito consists of just two elements: a microscopic speck of Sollecito's DNA on a bra clasp that was apparently sliced off Kercher's back during the attack and another speck of biological substance compatible with Kercher on a kitchen knife picked by police at random from Sollecito's drawers after his arrest, with Knox's DNA on the handle. Prosecutors say the two college students spent a sleepless night...
