You know the parlor game. Pick a famous person and figure out how you would contact him through the people you know. Guess what? It really works. The Associated Press reports that researchers at Columbia University set up a "Small World" experiment in which volunteers tried to get an e-mail message to a stranger somewhere else in the world. They were only given the person's name, location, profession, and educational background. The first e-mail was sent to someone the volunteer knew who was as close to the target as possible. That person was urged to send a message to a contact he or she knew. And so on. While many of the e-mail message chains died from lack of interest, the ones that worked took on average six e-mail messages to reach their destination.
More than 61,000 individuals from 166 countries participated, creating 24,163 message chains; however, only 384 actually reached their targets. Lead researcher Duncan J. Watts attributed the low success rate to fading interest. When a message was not forwarded, the chain died prematurely. But those that worked proved the "6 degrees of separation" parlor game to be right. "That estimate is five to seven, with an average of six," Watts told AP. "That is the true answer and that is what the world actually looks like from the point of view of how the network is connected."
The most successful chains had several elements in common.
Messages sent to a professional contact, rather than a friend, or to a remote acquaintance proved most effective. Why? Watts told AP that close friends tend to know the same people and have the same contacts, while more distant acquaintances are more likely to bring in new contacts that were unknown to the original sender. For example, if you were told to get a message to someone in Novosibirsk, Siberia, you should first send it to someone who has traveled in Russia or works with someone who is Russian.
The experiment is being repeated. If you would like to participate, go to this URL: http://smallworld.columbia.edu.
What's the value in all this?
"Networks can contain a lot of resources, and if you learn how to navigate through them that can be a powerful tool for self advancement," Watts told AP. "The mechanisms people use to navigate networks are universal and this is a clean way to study that process and to find good strategies."
