Facebook Knocks "Six Degrees of Separation" Down a Few Notches (i-programmer.info)

mikejuk writes: Six degrees of separation is the, already well established, idea that any individual is connected to any other via six network nodes. New research has discovered that the average between Facebook users is just three and a half: "We know that people are more connected today than ever before. Over the past five years, the global Facebook community has more than doubled in size. Today we're announcing that during that same time period, the degrees of separation between a typical pair of Facebook users has continued to decrease to 3.57 degrees, down from 3.74 degrees in 2011. This is a significant reflection of how closely connected the world has become." This may all be true and Facebook makes us better connected, but it leaves the question of the quality of the connections open. Are Facebook friends anything like real friends?

    I you have my back! ZERO-DEGREES of!

    I like back bacon.

    As far as facebook goes, the point of 6 degrees is a hypothetical favor network. A friend is someone you can aska fvor from. maybe a small favor like an introduction. that's why the concept of degrees of separation makes sense. Facebook freinds are not freinds. In some case facbook can be useful for tracing the spread of social disease however.

  28. Not Entirely Bullshit by whodunit · · Score: 1

    While it is quite true that many people have friends lists in the hundreds, simply because they can, I have personally seen how Facebook can kind of act as a "network map" of social relationships. For instance, just starting with my friends from high school, I can see which friends of mine independently knew one another. I can also see who they know that I don't; and investigating them leads me to discover a whole new "circle" of mutual friends; people who's names and faces I knew, but who's social dealings I was unaware of.

    The above observations came about by recognizing patterns in usernames posting on each other's feeds; in other words people whom actually interact with each other. Facebook is an incredibly powerful tool for studying social relationships (within the bounds of its demographic capture, of course,) if it's utilized in a proper manner. That certianly does not apply to some pap written by a Facebook PR staffer, (though it was nicely written, at least,) but don't let that obscure the real scientific value that can be gleaned from more intensive, focused observations. Facebook must be sociologist catnip; all those social interactions - many of them tied into "real life" via phone/geotagging integration - laid out on a table for easy perusal and analysis.

    Probably massively distorted by stars who accept all friend requests and serve as hubs.

    Basically, when you make such a rule, you should have some kind of minimum standard for what qualifies as a "connection". If you bring it down to FB standards, which basically is "I once saw you from afar on the street", the distance is minimal. In real-world terms, if you actually would use "once saw you on the street", I'm fairly sure even for large cities the average would be something like 1.8

  31. First of all I am a nobody who is 3 from the Queen by EmperorOfCanada · · Score: 1

    I am a nobody in Canada and know someone who knows someone who regularly dines with the Queen. I am willing to bet though, that I could dig up a bushman who is 8 or more degrees from me. Also I suspect that Facebook is a bit distorted in that many of the people on Facebook are social vs most people not being terribly social. So being quickly connected to the queen is no huge surprise as she is the center of a vast social network. Her footman's kid is then 5 away from me. Her footman's kid's neighbour is probably the classic 6.

    So where facebook statement is probably over generalized to the population is to forget that like the queen, many people on facebook are probably important nodes in the social fabric of western society. Thus many people know someone on facebook who is nearly 4 degrees from someone who that person knows who doesn't use facebook. Otherwise known as 6 degrees.

    So a facebook made up of Clintons would be all two degrees, a facebook made up of Unibombers would all be 40 degrees.

  32. Uh . . . missing a bit of data are we? by rhyous · · Score: 1

    There are some problems with their data and their assumptions:

    Problem 1:
    Facebook has 1.5 billion users. Of those, 1/3 are considered fake or duplicate accounts or have died. So 1 billion real/valid users. The world has 7 billion people. So Facebook has shown that of people who join facebook, the degree of separation is lowering to 3.57. What does this mean for those not on Facebook.

    Problem 2:
    A friend isn't a friend on Facebook. Guess what. Just because two people agree to "friend" each other, doesn't make them "Friends". Most people have far fewer people they could contact directly than they have friends. For example, a lot of my friends are my friends. But really we are separated by my wife, even though Facebook has us marked as not separated.
