Six Degrees of Separation down to 3.5


If data released by Facebook is to be believed, the famous “Six degrees of Separation" theory is set to change. Facebook has just upended this theory that every person on this planet is connected to everyone else by six other people, meaning that the world is more closely connected than we have ever thought.

After the results of a massive study went public, it has been established that there is actually "three and a half degrees of separation" where each person in the world is connected to every other person by an average of three-and-a-half other people.

Mark Zuckerberg has released this finding after his company concluded a study of 1.59 billion people active on the social networking website.

The stuff can be explained as follows:
Imagine a person with 100 friends. If each of his friends also has 100 friends, then the number of friends-of-friends will be 10,000.

If each of those friends-of-friends also has 100 friends then the number of friends-of-friends-of-friends will be 1,000,000.

Some of those friends may certainly overlap, so to filter down to unique connections, statistical algorithms are used to estimate distances with great accuracy, basically finding the approximate number of people within 1, 2, 3 (and so on) hopping away from a source.


For the theory now stands modified, due credit stands for Hungarian playwright Frigyes Karinthy in 1929 who coined "Six degrees of Separation".
